Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority on the basis of China Patent Application No. 201811629002.1 filed December 28, 2018 and incorporated herein by reference in its entirety.

FIELD OF TECHNOLOGY

[0002] This invention relates to telecommunication technologies, namely to a method for switching the reception mode and to a terminal device.

BACKGROUND OF THE INVENTION

[0003] In fifth generation mobile communication technologies (Fifth-generation, 5G), terminal devices operating in certain bands (for example, 2.6 GHz, 3.5 GHz or 4.8 GHz) must support four receiving antennas. However, in some cases, two receiving antennas may be sufficient to fulfill all requirements. For example, if the downlink information is small data packets, then requirements such as Quality of Service (QoS) can be met in the dual antenna receive mode. If the terminal device continues to use four antennas to receive information on the downlink, then excess power consumption occurs, degrading the consumer properties of the terminal device. In addition, for a terminal device that supports operation in the high frequency band (6 GHz or higher), you can install multiple antenna panels (Panel) so that the terminal device independently selects which antenna panels to use for downlink signal reception.

[0004] In the prior art, a base station may use Radio Resource Control (RRC), Media Access Control (MAC), or physical layer signaling to configure a terminal to operate with four receive antennas ( hereinafter for brevity - 4 antennas, or 4Rx) or two receiving antennas (hereinafter for brevity - 2 antennas, or 2Rx). However, if the base station performs the tuning, the base station sends more signaling data, which increases the load on the communication channel.

SUMMARY OF THE INVENTION

[0005] It is an object of the embodiments of the present invention to provide a reception mode switching method and a terminal that solves the problem of increasing the amount of signal data from the base station due to the base station performing tuning of the receiving antenna of the terminal.

[0006] The first embodiment of the present invention implements a receive mode switching method applied to a terminal, including:

switching the terminal from the first receive mode to the second receive mode if a receive mode switch event occurs.

[0007] A second embodiment of the present invention further provides a terminal device, including:

a processing module configured to switch the terminal from the first receive mode to the second receive mode if a receive mode switch event occurs.

[0008] A third embodiment of the present invention further provides a terminal device including a processor, a memory, and a program that is stored in the memory and can run on the processor. During program execution on the processor, the steps of the reception mode switching method according to the first embodiment of the present invention are implemented.

[0009] A fourth embodiment of the present invention further provides a computer-readable storage medium. This computer-readable storage medium stores a computer program that, during its execution on the processor, implements the steps of the reception mode switching method according to the first embodiment of the present invention.

[0010] In embodiments of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changed . Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0033] Embodiments of the present invention are described below with reference to the accompanying drawings. The reception mode switching method and terminal device that are implemented in the embodiments of the present invention can be applied to a wireless communication system. In FIG. 1 is a schematic diagram of the architecture of a wireless communication system in accordance with an embodiment of the present invention. As shown in FIG. 1, a wireless communication system may include a network device 10 and a terminal device. The terminal device is referred to as the user equipment (User Equipment, UE) 11 and may interact (transmit signals or data) with the network device 10. In real-world applications, the connection between the above devices may be wireless. In FIG. 1, for a convenient and visual representation of the connection between devices, a solid line is used. It should be noted that the communication system may include a plurality of UEs 11 and the network device 10 may communicate with a plurality of UEs 11.

[0034] The terminal device provided in the embodiments of this invention may be a mobile phone, tablet computer, laptop, ultra-mobile personal computer (Ultra-Mobile Personal Computer, UMPC), netbook, personal digital assistant (Personal Digital Assistant, PDA), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device), on-board device or their equivalents.

[0035] The network device 10 provided in the embodiments of the present invention may be a base station, including a conventional base station or an evolved node base station (eNB), as well as a network device in a 5G system, such as a device ( next generation node base station (gNB) or transmission and reception point (TRP)).

[0036] As shown in FIG. 2, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0037] Act 201: Switch the tag from the first receive mode to the second receive mode if a receive mode switch event occurs.

[0038] After act 201, the terminal may optionally transmit to the network side (eg, base station) information related to the second receive mode.

[0039] This embodiment of the present invention imposes no restrictions on the contents of the receive mode switch event. The receive mode switch event may be an event associated with a reduction in power consumption of a terminal device or an improvement in the performance of a terminal device. When a receive mode switch event occurs, the terminal may switch from the first receive mode to the second receive mode in order to reduce the power consumption of the terminal or improve the performance of the terminal. In the absence of a receive mode switch event, the terminal continues to operate in the current receive mode.

[0040] In this embodiment of the present invention, the receiving mode of the terminal is an operating mode in which the terminal receives signals using a certain number of receiver elements. The receiving elements may be: a receiving antenna, a receiving antenna port, a receiving port, a receiving channel, an RF receiving channel, or a receiving antenna panel.

[0041] The number of receive modes at the tag may be greater than or equal to 2. For example, the receive mode at the tag may include a first receive mode and a second receive mode, or a first receive mode, a second receive mode, and a third receive mode. Obviously, the reception mode switching method for the case when the number of reception modes in the terminal device is greater than 2 is similar to the reception mode switching method for the case when the number of reception modes in the terminal device is 2. A detailed description will not be given here.

[0042] In this embodiment of the present invention, the terminal device automatically performs a receive mode switch when a receive mode switch event occurs, which solves the problem of increasing the amount of signaling data from the base station due to the fact that such a setting is usually performed by the base station, and also reduces power consumption. terminal device, thereby improving the performance of the terminal device.

[0043] As shown in FIG. 3, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0044] Act 301. Determine if a receive mode switch event occurs, and if a receive mode switch event occurs, perform act 302, otherwise perform act 303.

[0045] Act 302: Switch the terminal from the first receive mode to the second receive mode.

[0046] In this way, the terminal device automatically performs a receive mode switch when a receive mode switch event occurs, which solves the problem of increasing the amount of signal data from the base station due to the fact that such adjustment is usually performed by the base station, and also reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0047] After act 302, the terminal may optionally transmit to the network side (eg, base station) information related to the second receive mode. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[0048] Act 303: Continue the terminal in the current receive mode.

[0049] For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[0050] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. For example, the first quantity may be 2 and the second quantity may be 4, or the first quantity may be 4 and the second quantity may be 2. Obviously, this embodiment of the present invention does not impose restrictions on the values of the first quantity and the second quantity. .

[0051] For example, the receive mode at the terminal may include a first receive mode and a second receive mode, where the first receive mode corresponds to two receive elements and the second receive mode corresponds to four receive elements. The current receive mode on the terminal device is the first receive mode. Determining whether a receive mode switch event occurs is performed using the procedure shown in FIG. 3. If a receive mode switch event occurs, then the terminal device switches from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode on the terminal device does not change and the terminal device continues to operate in the first receive mode. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[0052] It should be noted that alternatively, in the above example, the first receive mode may correspond to four receive elements, and the second receive mode may correspond to two receive elements.

[0053] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0054] As shown in FIG. 4, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0055] Act 401: Determine if the Wake Up Signal (WUS) indicates to the terminal to monitor the Physical Downlink Control Channel (PDCCH) during the CDRX enable timer, and if the WUS signal indicates to the terminal for the device to monitor the PDCCH during the wake-up timer, take action 402, and otherwise take action 403.

[0056] If necessary, the terminal may receive the WUS signal in the first receive mode. In this case, the WUS signal must arrive before or during the activation of the onduration timer when connected (Connected Discontinuous Reception, CDRX). The WUS is associated with the PDCCH via an on timer and indicates to the terminal whether to monitor the PDCCH.

[0057] Act 402: Determine that a receive mode switch event has occurred and perform act 404.

[0058] Act 403: Determine that a receive mode switch event has not occurred and perform act 405.

[0059] Act 404: Switch the terminal from the first receive mode to the second receive mode.

[0060] After act 404, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[0061] Act 405: Continue the terminal in the current receive mode.

[0062] If the terminal has not received a WUS that the terminal should monitor the PDCCH during the CDRX on timer, or if the terminal has received a WUS that the terminal should not monitor the PDCCH during the on timer CDRX, then the receive mode switch event is considered not to have occurred and the receive mode on the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[0063] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[0064] The method shown in FIG. 4 may apply to the following scenario: the terminal receives a WUS signal before or during the CDRX on timer, which indicates to the terminal whether to monitor the PDCCH during the CDRX on timer. Based on the received WUS signal, the terminal monitors or does not monitor the PDCCH during the wake-up timer.

[0065] For example, in CDRX, the terminal receives the WUS signal via 2Rx (two receivers, or two receive antennas). If the WUS signal received by the terminal instructs the terminal to monitor the PDCCH during the CDRX enable timer, then adaptive antenna switching is performed (for example, switching to 4RX is performed), otherwise, no switching is performed (for example, switching to 4Rx is not performed). ). After switching to 4Rx (4 receivers, or 4 receiving antennas), the terminal can optionally report 4Rx-related information to the next generation NodeB (gNB).

[0066] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0067] As shown in FIG. 5, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0068] Act 501: Determining whether the intermittent receive/inactivity timer on connection (CDRX-Inactivity timer) is running on the terminal when the terminal is operating in the first receive mode, and if the CDRX idle timer is running, taking action 502, otherwise perform action 503.

[0069] Act 502: Determine that a receive mode switch event has occurred and perform act 504.

[0070] Act 503: Determine that a receive mode switch event has not occurred and perform act 505.

[0071] Act 504: Switch the tag from the first receive mode to the second receive mode.

[0072] After act 504, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[0073] Act 505: Continue the terminal in the current receive mode.

[0074] If the CDRX sleep timer on the terminal is not running, then the receive mode switch event is considered not to have occurred and the receive mode on the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[0075] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[0076] The method shown in FIG. 5 may apply to the following scenario: while the CDRX enable timer expires, the terminal monitors the PDCCH. When scheduling information is received on the PDCCH, the CDRX sleep timer is started and PDCCH tracking continues, and if no scheduling information is received on the PDCCH, the terminal switches to Discontinuous Reception (DRX) switched off (OFF) at the end of the on timer.

[0077] For example, if the CDRX idle timer is not running when the wake-up timer expires, then the terminal can operate on 2Rx and receive information on the PDCCH over 2Rx. If the CDRX idle timer is running, then adaptive antenna switching is performed (eg, switching to 4RX is performed), otherwise, no switching is performed (eg, switching to 4Rx is not performed). After switching to 4Rx, the terminal may optionally report 4Rx-related information to the gNB node.

[0078] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0079] As shown in FIG. 6, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0080] Act 601: Determining whether the tag received the scheduling information sent on the target PDCCH at a predetermined time when the tag was operating in the first receive mode, and if the scheduling information sent on the PDCCH was not received for a predetermined time, performing action 602, otherwise performing action 603.

[0081] If necessary, the cyclic redundancy check (CRC) of the target PDCCH channel can be scrambled with a Cell Radio Network Temporary Identifier (C-RNTI) or a temporary Radio Network Configuration Scheduling Identifier (Configured Scheduling RNTI, CS-RNTI) .

[0082] It should be noted that this embodiment of the present invention imposes no restrictions on the value of the predetermined time. If necessary, the value of the preset time can be configured by the network or protocol.

[0083] Act 602: Determine that a receive mode switch event has occurred and perform act 604.

[0084] Act 603: Determine that a receive mode switch event has not occurred and perform act 605.

[0085] Act 604: Switch the terminal from the first receive mode to the second receive mode.

[0086] After act 604, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[0087] Act 605: Continue the terminal in the current receive mode.

[0088] If the tag does not receive scheduling information transmitted on the target PDCCH within a predetermined time, then the receive mode switch event is considered not to have occurred and the receive mode at the tag does not change. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[0089] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be greater than the second quantity. For example, the first number may be 4 and the second number may be 2. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[0090] The method shown in FIG. 6 may apply to the following scenario: if in the active Radio Resource Control (RRC) mode, the terminal device does not receive within a certain time (timer) in the active (active) part of the bandwidth (Bandwidth Part, BWP) scheduling information transmitted on the PDCCH, the terminal switches to a portion of the default downlink bandwidth.

[0091] For example, if the terminal is operating in RRC active mode on 4Rx and does not receive scheduling information on the active part of the bandwidth (BWP) on the PDCCH within a predetermined time, then the terminal switches to part of the bandwidth (BWP) downlink by default. In addition, adaptive antenna switching is triggered and the terminal switches to a mode with fewer antennas (for example, if the terminal operates in Active Bandwidth (BWP) on 4Rx, then the terminal switches to 2Rx), otherwise it continues to operate on 4Rx.

[0092] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[0093] As shown in FIG. 7, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[0094] Act 701. Determine if the terminal device received a paging message when the terminal device was operating in the first receive mode, and if the paging message is received and related to this terminal device, perform action 702, otherwise, perform the action 703.

[0095] Act 702: Determine that a receive mode switch event has occurred and perform act 704.

[0096] Act 703: Determine that a receive mode switch event has not occurred and perform act 705.

[0097] Act 704: Switch the terminal from the first receive mode to the second receive mode.

[0098] After act 704, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[0099] Act 705: Continue the terminal in the current receive mode.

[00100] For example, if the terminal has not received a paging message, or if the terminal has received a paging message that is not related to the terminal, then the receive mode switch event is considered not to have occurred and the receive mode on the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00101] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00102] In this embodiment of the present invention, a tag related paging message may include at least one of the following information blocks:

information carried on the PDCCH or on the Physical Downlink Shared Channel (PDSCH) information for the paging message, including information related to terminal ID, system information update, warning system earthquakes and tsunamis (Earthquake Tsunami Warning System, ETWS) or the Commercial Mobile Alert System (CMAS).

[00103] In this embodiment of the present invention, the non-terminal paging message excludes any of the following information blocks:

information carried on the PDCCH or PDSCH for the paging message, including information related to terminal ID, system information update, ETWS earthquake and tsunami warning system, or CMAS commercial mobile emergency alert system.

[00104] The method shown in FIG. 7 can be applied to the following scenario: in RRC idle mode or RRC active mode (RRC idle/active mode), the terminal device monitors the paging message at a specified interval, and the paging message indicates an update of the System Information (SI) or the presence of downlink data for the terminal.

[00105] For example, if the terminal received a paging message over 2Rx and the system is paging the terminal, then adaptive antenna switching is performed (e.g., switched to 4Rx) to receive subsequent information, otherwise the terminal continues to operate on 2Rx .

[00106] For example, if a terminal has received a paging message over 2Rx and the system is paging the terminal but the cause of the paging is not a system information update, then adaptive antenna switching is performed (e.g., switching to 4Rx is performed), otherwise the terminal the device continues to operate on 2Rx.

[00107] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00108] As shown in FIG. 8, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00109] Act 801. Determine if the WUS signal instructs the terminal to monitor the corresponding paging message, and if the WUS signal received by the terminal instructs the terminal to monitor the corresponding paging message, proceed to act 802, otherwise, perform act 803.

[00110] Optionally, the WUS signal may be received in the first receive mode prior to the Paging Occasion (PO) and may be associated with this paging event and also indicate to the terminal whether to monitor the PDCCH.

[00111] Act 802: Determine that a receive mode switch event has occurred and perform act 804.

[00112] Act 803: Determine that a receive mode switch event has not occurred and perform act 805.

[00113] Act 804: Switch the terminal from the first receive mode to the second receive mode.

[00114] After act 804, the corresponding information about the second receive mode may be transmitted to the network side, if necessary. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00115] Act 805: Continue the terminal in the current receive mode.

[00116] If the tag has not received a WUS signal that the tag should monitor the corresponding paging message, or if the tag has received a WUS signal that the tag should not monitor the corresponding paging message, then the receive mode switch event is considered to be has not occurred and the receive mode on the terminal device does not change. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00117] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00118] The method shown in FIG. 8 can be applied to the following scenario: In RRC idle mode or RRC active mode, the terminal monitors a paging message at a specified interval (e.g., every paging cycle) and the WUS signal arrives before the paging event (Paging Occasion, PO ) and indicates to the end device whether to monitor the corresponding paging message.

[00119] For example, the terminal may receive the WUS signal over 2Rx prior to the PO paging event. If the WUS signal received by the terminal instructs the terminal to monitor the corresponding paging message, then adaptive antenna switching is performed to switch the terminal to 4Rx to receive the paging message, otherwise, no switching to 4Rx is performed.

[00120] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00121] As shown in FIG. 9, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00122] Act 901: Receipt of the WUS signal that was received by the terminal in the first receive mode prior to the paging event is associated with that paging event and indicates to the terminal whether or not to monitor the PDCCH.

[00123] Act 902. Determining whether the WUS signal instructs the terminal to monitor the corresponding paging message, and if the WUS signal instructs the terminal to monitor the corresponding paging message and the paging message received by the terminal in the first receive mode is for the terminal, performing action 903, otherwise performing action 904.

[00124] Act 903: Determine that a receive mode switch event has occurred and perform act 905.

[00125] Act 904: Determine that a receive mode switch event has not occurred and perform act 906.

[00126] Act 905: Switch the terminal from the first receive mode to the second receive mode.

[00127] After act 905, the terminal may optionally transmit to the network side information related to the second receive mode. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00128] Act 906: Continue the terminal in the current receive mode.

[00129] For example, if the terminal received a WUS signal that the terminal should not monitor the corresponding paging message, or if the terminal received a WUS signal that the terminal should monitor the corresponding paging message, but the received paging message does not apply to given terminal, then the receive mode switch event is considered not to have occurred and the receive mode on the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00130] It should be noted that if the terminal has not received a WUS signal instructing the terminal to monitor the corresponding paging message, then the receive mode switch event is considered not to have occurred and the receive mode at the terminal is not changed.

[00131] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00132] In this embodiment of the present invention, a tag related paging message may include at least one of the following information blocks:

information carried on the PDCCH or PDSCH for the paging message, including information related to terminal ID, system information update, ETWS earthquake and tsunami warning system, or CMAS commercial mobile emergency alert system.

[00133] In this embodiment of the present invention, the non-terminal paging message excludes any of the following information blocks:

information carried on the PDCCH or PDSCH for the paging message, including information related to terminal ID, system information update, ETWS earthquake and tsunami warning system, or CMAS commercial mobile emergency alert system.

[00134] The method shown in FIG. 9 may apply to the following scenario: In RRC idle mode or RRC active mode, the terminal monitors the paging message at a specified interval (e.g., every paging cycle), and the WUS signal arrives before the paging event (Paging Occasion, PO ) and indicates to the end device whether to monitor the corresponding paging message.

[00135] For example, a terminal may receive a WUS signal over 2Rx prior to the PO paging event. If the WUS signal instructs the terminal to monitor the corresponding paging message, then the terminal receives the paging message via 2Rx. If the paging message indicates that the system is paging the terminal, then adaptive antenna switching is performed on 4Rx to receive further information, otherwise the terminal continues to operate on 2Rx.

[00136] For example, the terminal may receive the WUS signal over 2Rx prior to the PO paging event. If the WUS signal instructs the terminal to monitor the corresponding paging message, then the terminal receives the paging message via 2Rx. If the paging message indicates that the system is paging the terminal, but the cause of the paging is not an update of system information, then adaptive antenna switching is performed on 4Rx to receive further information, otherwise the terminal continues to operate on 2Rx.

[00137] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00138] As shown in FIG. 10, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00139] Act 1001. Determining whether a portion of the default downlink bandwidth (default Downlink BWP) has timed out when the terminal is in the first receive mode and is in RRC connected mode, and if timed out, perform action 1002, otherwise perform action 1003.

[00140] Act 1002. Determine that a receive mode switch event has occurred and perform act 1004.

[00141] Act 1003. Determine that a receive mode switch event has not occurred and perform act 1005.

[00142] Act 1004: Switch the terminal from the first receive mode to the second receive mode.

[00143] After act 1004, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00144] Act 1005: Continue the terminal in the current receive mode.

[00145] If the default downlink portion of the bandwidth (BWP) has not timed out, then the receive mode switch event is considered not to have occurred and the receive mode at the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00146] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be greater than the second quantity. For example, the first number may be 4 and the second number may be 2. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00147] For example, the terminal device can be in the RRC connected mode (RRC connected) and work through 4Rx, and if the scheduling information transmitted on the PDCCH channel has not been received within a predetermined time (timer), then adaptive antenna switching is performed on 2Rx, otherwise the end device continues to operate on 4Rx.

[00148] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00149] As shown in FIG. 11, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00150] Act 1101. Determining whether the terminal device enters the sleep mode or the sleep mode from the RRC connection mode, where the first receive mode is configured for the terminal device that is in the RRC connection mode, and if the terminal device enters the idle mode or idle mode from the RRC connected mode, performing act 1102, otherwise performing act 1103.

[00151] Act 1102. Determine that a receive mode switch event has occurred and perform act 1104.

[00152] Act 1103. Determine that a receive mode switch event has not occurred and perform act 1105.

[00153] Act 1104: Switch the tag from the first receive mode to the second receive mode.

[00154] After act 1104, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00155] Act 1105: Continue the terminal in the current receive mode.

[00156] For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00157] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be greater than the second quantity. For example, the first number may be 4 and the second number may be 2. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00158] For example, the terminal device may be in RRC connected mode and operate via 4Rx, and if the terminal device enters idle mode (idle) or inactive mode (inactive), then adaptive antenna switching to 2Rx is performed.

[00159] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal device is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal device is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00160] As shown in FIG. 12, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00161] Act 1201. Determining whether the terminal enters the RRC connection mode from the idle or idle mode, where the first receive mode is configured for the terminal device while in the idle or idle mode, and if the terminal enters the RRC mode -connections from idle or idle mode, perform action 1202, otherwise perform action 1203.

[00162] Act 1202. Determine that a receive mode switch event has occurred and perform act 1204.

[00163] Act 1203. Determine that a receive mode switch event has not occurred and perform act 1205.

[00164] Act 1204: Switch the terminal from the first receive mode to the second receive mode.

[00165] After act 1204, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00166] Act 1205: Continue the terminal in the current receive mode.

[00167] For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00168] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00169] For example, a terminal in idle or idle mode operates on 2Rx and transitions to an RRC connection mode, and then adaptive antenna switching to 4Rx is performed.

[00170] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00171] As shown in FIG. 13, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00172] Act 1301. Determining whether the measured value of the target signal at the terminal is less than a predetermined threshold when the terminal is operating in the first receive mode or configured to the first receive mode, and if the measured value is less than the predetermined threshold values, performing action 1302, otherwise performing action 1303.

[00173] In this embodiment of the invention, the target signal may be a Synchronization Signal and PBCH block (SSB), a CSI Reference Signal (CSI-RS), or equivalent.

[00174] In this embodiment of the present invention, the measured value can be the power of the received pilot signals (Reference Signal Receiving Power, RSRP), the quality of the received pilot signals (Reference Signal Receiving Quality, RSRQ), the signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) or equivalent.

[00175] This embodiment of the present invention imposes no restrictions on the predetermined threshold value. If necessary, the threshold value can be configured by the network or protocol.

[00176] Act 1302. Determine that a receive mode switch event has occurred and perform act 1304.

[00177] Act 1303. Determine that a receive mode switch event has not occurred and perform act 1305.

[00178] Act 1304: Switch the terminal from the first receive mode to the second receive mode.

[00179] After act 1304, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00180] Act 1305: Continue the terminal in the current receive mode.

[00181] If the measured value of the target signal at the terminal exceeds a predetermined threshold value, then the receive mode switch event is considered not to have occurred and the receive mode at the terminal does not change. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00182] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00183] For example, the base station may be configured to operate over 2Rx, or the terminal may operate over 2Rx. If the measured value (for example, RSRP, RSRQ, or SINR) of the target signal (for example, SSB or CSI-RS) at the terminal meets a predetermined condition, for example, if the value of RSRP, RSRQ, or SINR is less than a predefined threshold, then adaptive switching antennas (for example, switching to 4Rx), and if the value of RSRP, RSRQ or SINR is greater than a predefined threshold, then the terminal continues to operate on 2Rx. After switching to 4Rx, the terminal may optionally report 4Rx-related information to the gNB node.

[00184] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00185] As shown in FIG. 14, an embodiment of the present invention provides a reception mode switching method implemented by a terminal. The sequence of actions should be as follows:

[00186] Act 1401. Determining whether the terminal has detected the initial signal (initial signal) of a new radio communication system without a license (NR unlicensed, NRU), where the terminal device is operating in the first receive mode or configured to the first receive mode, and if the initial signal detected, perform action 1402, otherwise perform action 1403.

[00187] Act 1402. Determine that a receive mode switch event has occurred and perform act 1404.

[00188] Act 1403. Determine that a receive mode switch event has not occurred and perform act 1405.

[00189] After act 1404, the terminal may optionally transmit information related to the second receive mode to the network side. For example, the terminal may notify the network side (such as the base station) that the terminal has switched to the second receive mode.

[00190] Act 1405: Continue the terminal in the current receive mode.

[00191] If the original NRU system signal is not detected by the terminal, then the receive mode switch event is considered not to have occurred and the receive mode at the terminal is not changed. For example, the terminal may continue to operate in the first receive mode and not switch to the second receive mode.

[00192] The first receive mode corresponds to the first number of receive elements on the tag, and the second receive mode corresponds to the second number of receive elements on the tag. In this case, the first quantity must be less than the second quantity. For example, the first number may be 2 and the second number may be 4. No restrictions are placed on this aspect. Alternatively, the receiver elements on the terminal device in the first mode may be the same in number as the receiver elements on the terminal device in the second mode, but differ only in composition. For example, the first mode may correspond to the first antenna array and the second mode may correspond to the second antenna array.

[00193] For example, in a new radio system without a license (NR unlicensed, NRU), the base station is configured to operate via 2Rx or the terminal device operates with 2Rx, and if the terminal device detects the original signal, then adaptive antenna switching to 4Rx is performed. If the end device does not detect the original signal, then the end device continues to operate on 2Rx. After switching to 4Rx, the terminal may optionally report 4Rx-related information to the gNB node.

[00194] In this embodiment of the present invention, if a receive mode switch event occurs, then the receive mode on the terminal is changed by switching from the first receive mode to the second receive mode, and if the receive mode switch event does not occur, then the receive mode of the terminal is not changes. Thus, the reception mode at the terminal device is automatically switched when a reception mode switching event occurs, which reduces the amount of signaling data from the base station and at the same time reduces the power consumption of the terminal device, thereby improving the performance of the terminal device.

[00195] An embodiment of the present invention further provides a tag. Since the problem solving principle for a terminal device is similar to the problem solving principle described in the receive mode switching method in the embodiments of the present invention, the implementation of the method should be based on the implementation of the terminal device. The detailed description is no longer provided in this document.

[00196] As shown in FIG. 15, an embodiment of the present invention further provides a tag 1500 including:

[00199] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to do the following: if the WUS wake-up signal received by the terminal instructs the terminal not to monitor the PDCCH during the CDRX enable timer, or if the terminal has not received a WUS signal instructing the terminal to monitor the PDCCH during the CDRX enable timer, no receive mode switch event occurs and the receive mode on the terminal does not change.

[00200] The WUS signal must be received in the first receive mode and be associated with the PDCCH through an on timer.

[00201] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the intermittent reception/idle connection timer (CDRX idle timer) on the terminal device is started, then a receive mode switch event occurs and the terminal device switches from the first reception mode to the second reception mode.

[00204] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the terminal device has not received scheduling information transmitted on the target PDCCH in a predetermined time, then the receive mode switch event does not occur and the receive mode on the terminal is not changed.

[00205] In this embodiment of the present invention, the CRC of the target PDCCH may be further scrambled with C-RNTI or CS-RNTI.

[00206] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if a terminal device has received a paging message that relates to this terminal device, then a receive mode switch event occurs and the terminal device switches from the first receive mode to second receiving mode.

[00208] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following: if the WUS signal received by the terminal instructs the terminal to monitor the corresponding paging message, then a receive mode switch event occurs.

[00209] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the WUS signal received by the terminal device instructs the terminal device not to monitor the corresponding paging message, or if the terminal device has not received a WUS signal indicating terminal to monitor the corresponding paging message, no receive mode switch event occurs and the receive mode at the terminal does not change.

[00210] The WUS signal must be received before the paging event and be associated with this paging event.

[00212] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to do the following: if the terminal has not received a WUS that the terminal should monitor the corresponding paging message, or if the terminal has received the WUS that the end device should not monitor the corresponding paging message, or if the end device received a WUS signal that the end device should monitor the corresponding paging message, but the received paging message does not apply to this end device, then the receive mode switch event does not occur and the receive mode on the terminal is not changed.

[00213] The WUS signal must be received before the paging event and be associated with this paging event.

[00214] In this embodiment of the present invention, a tag related paging message may include at least one of the following information blocks:

information carried on the PDCCH or PDSCH for the paging message, including information related to terminal ID, system information update, ETWS earthquake and tsunami warning system, or CMAS commercial mobile emergency alert system.

[00215] A non-terminal paging message excludes any of the following information blocks:

information carried on the PDCCH or PDSCH for the paging message, including information related to terminal ID, system information update, ETWS earthquake and tsunami warning system, or CMAS commercial mobile emergency alert system.

[00216] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the default downlink portion of bandwidth (BWP) timeout has elapsed, then a receive mode switch event occurs and the terminal switches from the first reception mode to the second reception mode.

[00217] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to perform the following: if the default downlink portion of bandwidth (BWP) has not timed out, then the receive mode switch event does not occur, and the receive mode on the terminal device does not change.

[00218] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the terminal device enters idle or sleep mode from the RRC connection mode, then a receive mode switch event occurs and the terminal device switches from the first mode receiving in the second receiving mode;

or

if the terminal device enters the RRC connection mode from the sleep mode or the idle mode, then a receive mode switch event occurs and the terminal device switches from the first receive mode to the second receive mode.

[00219] In this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the measured value of the target signal at the terminal is less than a predetermined threshold, then a receive mode switch event occurs and the terminal switches from the first mode reception in the second reception mode.

[00220] Alternatively, in this embodiment of the present invention, the processing module 1501 can be further configured to perform the following action: if the measured value of the target signal at the terminal is greater than a predetermined threshold value, then the receive mode switch event does not occur and the receive mode on the end device does not change.
