Description

Transmission method, device and system for uplink transmit diversity

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method, an apparatus, and a system for uplink transmit diversity.

Background

The uplink transmit diversity technology can reduce the terminal transmit power, improve the edge coverage, improve the cell capacity, and simultaneously improve the service transmission rate of cell edge users, thereby improving the user experience. Therefore, applying uplink transmit diversity techniques such as MIMO (Multiple-input Multiple-output) to uplink transmission of UMTS (universal mobile telecommunications system) can meet the requirements of UMTS uplink transmission for improving spectrum efficiency, uplink transmission coverage and further user peak rate.

In the prior art, in a scenario where an uplink transmit diversity technique is applied to UMTS uplink transmission, when a service is established, as shown in fig. 1, an RNC (radio network controller) may determine that a UE and a NodeB may transmit data using uplink transmit diversity and determine whether to activate uplink transmit diversity of the UE according to an uplink transmit diversity capability of the UE carried in an RRC (radio resource control protocol) connection establishment request sent by the UE (user equipment) and an uplink transmit diversity capability of a cell in an AUDIT sent by the NodeB (base station). When the RNC determines to activate the uplink transmit diversity of the UE, the RNC notifies the NodeB and the UE of activating the uplink transmit diversity of the UE through an RLSetupRequest (radio link setup request) and an RBSetupRequest (radio bearer setup request), respectively.

However, since it is determined whether to activate the uplink transmit diversity of the UE only at the time of service establishment, it is not possible to dynamically adjust the activation/deactivation of the uplink transmit diversity of the UE according to the current reference measurement correlation quantity such as the power and channel quality of the UE after the service establishment. Therefore, the prior art also proposes that after the service is established, the RNC dynamically adjusts the activation/deactivation of the uplink transmit diversity of the UE through the RB reconfiguration process and the RL reconfiguration process. The specific flow is shown in fig. 2.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art: after receiving the reference measurement related quantity reported by the UE or NodeB, the RNC determines whether to activate the uplink transmit diversity of the UE according to the reported reference measurement related quantity, and the real-time property reported by the UE or NodeB is determined by the measurement report period, which causes a problem of a large time delay, thereby resulting in poor timeliness and validity of the decision of whether to activate the uplink transmit diversity, and affecting uplink transmission.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The various techniques described herein may be used in various wireless communication systems, such as current 2G, 3G communication systems and next generation communication systems, such as global system for mobile communications (GSM), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Wideband Code Division Multiple Access (WCDMA), Frequency Division Multiple Access (FDMA), frequency division multiple access (OFDMA), Orthogonal Frequency Division Multiple Access (OFDMA), access (SC-FDMA), general packet radio service (GPRS, general packet radio access (GPRS), Long Term Evolution (LTE), and other such communication systems.

Various aspects are described herein in connection with a terminal and/or a base station controller.

A terminal, which may be wireless or wireline, may be a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a radio access network (e.g., RAN). Such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless terminal may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a Mobile station (MobileStation), a Mobile station (Mobile), a remote station (RemoteStation), an access point (AccessPoint), a remote terminal (remoterterminal), an access terminal (AccessTerminal), a user terminal (UserTerminal), a user agent (useeragent), a user equipment (UserDevice), or a user equipment (userreequipment).

The base station may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the base station may be a base station in GSM or CDMA (BTS), a base station in WCDMA (NodeB), or an evolved node b in LTE (NodeB or eNB or e-NodeB), and the present invention is not limited thereto.

The base station controller may be a Base Station Controller (BSC) in GSM or CDMA, or may be a Radio Network Controller (RNC) in WCDMA, and the present invention is not limited thereto.

Additionally, the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In order to effectively decide to activate or deactivate uplink transmit diversity in time and improve the quality of uplink transmission, the embodiment of the invention provides a transmission method of uplink transmit diversity.

When determining to activate the uplink transmit diversity of User Equipment (UE) according to the reference measurement related quantity of the UE, the base station sends an activation request instruction to an RNC (radio network controller); and the RNC informs the base station and the UE of activating the uplink transmit diversity according to the activation request indication.

Or the base station sends a deactivation request instruction to the RNC when determining to deactivate the uplink transmit diversity of the UE according to the reference measurement related quantity of the UE; and the RNC informs the base station and the UE of deactivating uplink transmit diversity according to the deactivation request indication.

It should be noted that, in the embodiment of the present invention, it is described by taking an example that the UE has two antennas, if the UE activates the uplink transmit diversity, that is, when the UE is in an activated state of the uplink transmit diversity, both the two antennas of the UE have data channel transmission, and when the UE deactivates the uplink transmit diversity, that is, when the UE is in a deactivated state of the uplink transmit diversity, only one of the two antennas of the UE transmits the data channel, and the other antenna does not transmit data or only transmits a supplemental pilot channel.

The present invention will be described in detail below with reference to specific examples.

As shown in fig. 3, the present embodiment may specifically implement the activation/deactivation of uplink transmit diversity of the UE according to the following steps.

101. The base station acquires a reference measurement related quantity of the UE.

In the embodiment of the present invention, the reference measurement related quantity of the UE includes information such as power and CQI (channel quality indication) of the UE.

For example, the NodeB may receive a measurement report of the UE periodically reported by the UE, and obtain a reference measurement related quantity of the UE from the measurement report.

102. And the base station determines to activate or deactivate the uplink transmit diversity of the UE according to the reference measurement related quantity of the UE.

In the embodiment of the present invention, the uplink transmit diversity may adopt several diversity modes, such as TSTD (time-division transmit diversity), OLTD (open loop transmit diversity), CLTD (closed loop transmit diversity), and MIMO (Multi-input Multi-Output).

In addition, the transmission modes of the uplink transmit diversity can be divided into two modes, namely antenna switching (antenna switching) and beam forming (Beamforming). The antenna switching transmission principle is that the UE measures the transmission power of 2 transmit antennas alternately, and then selects an antenna with low transmission power to transmit data according to a TPC (transmit power control) command word. The beam forming emission principle is that the UE traverses a plurality of beam forming factors, the forming factor with the maximum signal-to-noise ratio is presumed according to the power control command word, and the factor is used for weighting and sending data.

For example, the NodeB may decide to activate or deactivate uplink transmit diversity of the UE according to a preset activation condition, a reference measurement related quantity of the UE. Or, the NodeB may also detect a reference measurement related quantity of the NodeB itself, and determine to activate or deactivate uplink transmit diversity of the UE according to a preset activation condition, the reference measurement related quantity of the UE and the reference measurement related quantity of the NodeB. The reference measurement related quantity of the NodeB includes information of resource usage in the NodeB, receiver performance, and the like. The uplink transmit diversity of the activated UE may be uplink transmit diversity of the configured and started UE, and the uplink transmit diversity of the deactivated UE may be uplink transmit diversity of the de-configured and stopped UE.

103. The base station sends an activation request instruction to an RNC (radio network controller) when determining to activate the uplink transmit diversity of the UE, or sends a deactivation request instruction to the RNC when determining to deactivate the uplink transmit diversity of the UE;

for example, the NodeB may send an activation request indication/deactivation request indication of the uplink transmit diversity of the UE to the RNC according to the decision result in step 102. That is, when deciding to activate the uplink transmit diversity of the UE, the NodeB sends an activation request instruction to the RNC to activate the UE, and when determining to deactivate the uplink transmit diversity of the UE, the NodeB sends a deactivation request instruction to the RNC to deactivate the UE.

104. And the RNC informs the UE of activating the uplink transmit diversity according to the activation request indication or informs the UE of deactivating the uplink transmit diversity according to the deactivation request indication.

For example, the RNC may notify the UE to activate/deactivate uplink transmit diversity according to the activation request indication/deactivation request indication. Optionally, the RNC may also send a corresponding acknowledgement response to the NodeB when notifying the UE to activate/deactivate uplink transmit diversity. Or, the RNC may also send a corresponding activation/deactivation completion notification to the base station when it is known that the UE completes activation/deactivation of the uplink transmit diversity. For example, the RNC may notify the UE of the activation or deactivation of the uplink transmit diversity through an L3 signaling message. The L3 signaling message is an air interface RRC message, and may be, for example, a radio bearer reconfiguration. Or, the UE may also directly send a corresponding activation/deactivation completion notification to the base station through a physical channel when the activation/deactivation of the uplink transmit diversity is completed.

In addition, before the decision of activating/deactivating the uplink transmit diversity of the UE is made, the UE and the NodeB may respectively send the uplink transmit diversity capability to the RNC, so that the RNC knows that the UE and the NodeB have the capability of sending data using the uplink transmit diversity. The RNC may send configuration parameter information to the UE and the NodeB, respectively, after knowing that the UE and the NodeB have the capability of sending data using uplink transmit diversity, and the UE and the NodeB perform some configuration operations related to uplink transmit diversity according to the configuration parameter information.

In the uplink transmit diversity transmission method provided in this embodiment, the base station determines to activate/deactivate uplink transmit diversity of the UE according to the reference measurement correlation quantity of the UE and instructs the RNC to notify the UE of activating/deactivating the uplink transmit diversity. And the base station can more timely and effectively acquire the reference measurement related quantity of the UE, so that the judgment of the activation or deactivation of the uplink transmit diversity can be more timely and effectively carried out. And then can adjust the up run transmission mode suitable for the present transmission situation in time, effectively, thus has improved the quality of the up run transmission.

In the above embodiment, after receiving the activation request indication/deactivation request indication sent by the base station according to the decision result, the RNC may send an acknowledgement response to the base station while notifying the UE to activate/deactivate the uplink transmit diversity, or may send a completion notification to the base station when knowing that the UE completes activating/deactivating the uplink transmit diversity. The following takes the uplink transmit diversity scheme using OLTD diversity as an example, and further details the previous embodiment with reference to the above different situations.

As shown in fig. 4, the transmission method of uplink transmit diversity in this embodiment includes:

201. and the UE reports the reference measurement related quantity of the UE to the NodeB through a physical channel.

202. And the NodeB judges whether to activate/deactivate the uplink OLTD according to the reference measurement related quantity reported by the UE and the detected reference measurement related quantity of the base station.

For example, the NodeB may determine to activate/deactivate the uplink OLTD of the UE according to the power reported by the UE, the CQI, the resource usage (or related measurement volume) in the NodeB, and a preset activation/deactivation condition. The activation condition or the deactivation condition may be flexibly set according to the transmission requirement of the uplink data.

For example, suppose that the NodeB determines that the UE is currently in an out-of-synchronization state according to a received frame sent by the UE, and at this time, TPC is inaccurate, which may result in unreliable performance of uplink transmit diversity. Therefore, if the current UE is in the uplink OLTD activated state, the NodeB may determine to deactivate the uplink OLTD of the UE.

Or, assuming that the NodeB determines that the UE is always in a power limited state according to a UPH (UE power head from, transmission power space) reported by the UE, at this time, the power of a DPCCH (dedicated physical control channel) is also compressed, and a TPC command word fed back by the NodeB cannot reflect the actual condition of the channel, because the TPC command word is always a value of a raised power, which may cause the uplink transmit diversity performance to be degraded. Therefore, if the current UE is in the uplink OLTD activated state, the NodeB may determine to deactivate the uplink OLTD of the UE.

Or, assuming that the NodeB determines that the UE is moving at a high speed according to the action of the UE, for example, the UE frequently performs a handover operation in a short time, at this time, negative gain may be brought by using uplink transmit diversity. Therefore, if the current UE is in the uplink OLTD activated state, the NodeB may determine to deactivate the uplink OLTD of the UE.

Alternatively, it is assumed that the NodeB determines the receiver performance degradation from the detected reference measurement related quantity of the base station itself, which may affect the uplink transmit diversity performance. Therefore, if the current UE is in the uplink OLTD activated state, the NodeB may determine to deactivate the uplink OLTD of the UE.

Or, assuming that the NodeB determines, according to the CQI reported by the UE, that the CQI value is lower than a certain configured threshold for a certain duration, it may be determined that the channel quality between the NodeB and the UE is poor, which may affect the uplink transmit diversity performance. Therefore, if the current UE is in the uplink OLTD activated state, the NodeB may determine to deactivate the uplink OLTD of the UE.

If it is preset that the NodeB determines to deactivate the uplink OLTD of the UE only when the reference measurement related quantity of the UE and the reference measurement related quantity of the NodeB satisfy the above condition, the NodeB may determine to activate the uplink OLTD of the UE when neither the reference measurement related quantity of the UE nor the reference measurement related quantity of the NodeB satisfies the above condition.

203. And after the NodeB determines to activate/deactivate the uplink OLTD, the NodeB sends an activation/deactivation request instruction to the RNC.

For example, the NodeB may send an activation/deactivation request indication to the RNC through an Iub port, for example, the NodeB may send the activation/deactivation request indication to the RNC through an IubFP. And, the NodeB may send the activation/deactivation request indication through the existing signaling, for example, add a certain number of bits in the digital measurement request sent to the RNC, where the bits are used to indicate the activation/deactivation of the uplink OLTD of the UE, for example, when the NodeB decides to activate/deactivate the uplink OLTD of a certain UE, add the identity of the UE and a bit in the digital measurement request sent to the RNC, take the bit as an indication bit, indicate to deactivate the uplink OLTD of the UE when the indication bit is 0, and indicate to activate the uplink OLTD of the UE when the indication bit is 1. Alternatively, the NodeB may also send an activation request indication/deactivation request indication through an additional signaling.

In addition, the NodeB may also send the reason for activating/deactivating the uplink OLTD of the UE to the RNC at the same time when sending the activation/deactivation request indication to the RNC, for example, assuming that the NodeB sends the activation/deactivation request indication through the default message delivery report, a certain number of bits may be added to the default message delivery report, and different values of the bits are preset to indicate different activation/deactivation reasons. For example, the NodeB determines to deactivate the uplink OLTD of a certain UE because the UE is in a power-limited state, the NodeB may add the UE's identity and an indication bit and a reason representation bit in the default message, set the indication bit to 0 to indicate that the uplink OLTD of the UE is deactivated, and set the reason representation bit to 010 to indicate that the reason for deactivation is that the UE is in the power-limited state.

204. And after receiving the activation/deactivation request indication sent by the NodeB, the RNC returns a confirmation response to the NodeB.

For example, after receiving the activation/deactivation request indication sent by the NodeB, the RNC sends an activation/deactivation confirmation response of the uplink OLTD of the UE to the NodeB, and the NodeB performs corresponding adjustment according to the confirmation response, thereby ensuring that the NodeB and the UE are synchronized. For the adjustment processing method of the NodeB, reference may be made to the prior art, and details are not described here.

205. And the RNC sends a notice of activating/deactivating the uplink OLTD to the UE according to the activating/deactivating request indication while returning a confirmation response to the NodeB.

For example, when the RNC returns an acknowledgement response to the NodeB, the RNC may notify the UE of activating/deactivating the uplink OLTD through the RB reconfiguration request.

206. And the RNC receives a completion notice of activating/deactivating the uplink OLTD sent by the UE.

For example, the UE knows that it needs to activate/deactivate its uplink OLTD through the RB reconfiguration request, and after activating/deactivating the uplink OLTD is completed, the UE may send a completion notification of activating/deactivating the uplink OLTD to the RNC through the RB reconfiguration response, that is, notify the RNC that the UE has completed the operation of activating/deactivating the uplink OLTD. And after the UE completes activation of the uplink OLTD, the uplink OLTD is adopted to send uplink data.

As shown in fig. 5, the transmission method of uplink transmit diversity in this embodiment includes:

301. and the UE reports the reference measurement related quantity of the UE to the NodeB through a physical channel.

302. And the NodeB judges whether to activate/deactivate the uplink OLTD according to the reference measurement related quantity reported by the UE and the detected reference measurement related quantity of the base station.

The specific operation of this step can be referred to as step 202, and is not described herein again.

303. And after the NodeB determines to activate/deactivate the uplink OLTD, the NodeB sends an activation/deactivation request instruction to the RNC.

The specific operation in this step can be referred to as step 203, and is not described herein again.

304. And the RNC sends a notice of activating/deactivating the uplink OLTD to the UE according to the activating/deactivating request indication.

The specific operation in this step can be referred to as step 205, which is not described herein again.

305. And the RNC receives a completion notice of activating/deactivating the uplink OLTD sent by the UE.

The specific operation of this step can be referred to as step 206, which is not described herein again.

306. After receiving the activation/deactivation completion notification sent by the UE, the RNC sends an activation/deactivation completion notification to the NodeB.

Corresponding to the above embodiments, the present invention further provides a transmission method for uplink transmit diversity, including: the method comprises the steps that an RNC receives an activation request indication sent by a base station when the base station determines to activate the uplink transmit diversity of UE according to the reference measurement related quantity of the UE, and informs the UE to activate the uplink transmit diversity according to the activation request indication; or, the RNC receives a deactivation request indication sent by the base station when the base station determines to deactivate the uplink transmit diversity of the UE according to the reference measurement related quantity of the UE, and informs the UE to deactivate the uplink transmit diversity according to the deactivation request indication.

In addition, an embodiment of the present invention further provides a transmission method for uplink transmit diversity, including:

when the UE determines to activate the uplink transmit diversity according to the reference measurement related quantity of the UE, the UE sends a notice for activating the uplink transmit diversity of the UE to a base station;

or the UE sends a notice for deactivating the uplink transmit diversity of the UE to the base station when determining to deactivate the uplink transmit diversity according to the reference measurement related quantity of the UE.

As shown in fig. 6, the present embodiment may specifically implement the activation/deactivation of uplink transmit diversity of the UE according to the following steps.

401. The UE acquires a reference measurement related quantity of the UE;

for example, the UE may detect its own reference measurement related quantity.

402. And the UE determines to activate or deactivate the uplink transmit diversity of the UE according to the reference measurement related quantity of the UE.

For example, the UE may determine to activate/deactivate the uplink OLTD of the UE according to the detected reference measurement related quantity such as the power and the channel quality of the UE itself and a preset activation/deactivation condition. Alternatively, the UE may also receive the reference measurement related quantity of the NodeB, and determine to activate/deactivate the uplink OLTD of the UE according to the detected power and channel quality of the UE itself, the received reference measurement related quantity of the NodeB, and a preset activation/deactivation condition. The activation condition or the deactivation condition may be flexibly set according to the transmission requirement of the uplink data.

For example, assuming that the UE is in a CELL _ DCH (CELL dedicated channel) state, when the UE allocates a dedicated physical channel in uplink and downlink, the UTRAN (terrestrial radio access network-UMTS) may know the CELL level position of the UE according to the active set of the current UE, and the UE may use a dedicated transport channel, a downlink HS-DSCH (high speed downlink shared channel) channel, and a combination of these transport channels. In this state, if the current UE is in the uplink OLTD deactivation state, the UE may determine to activate the uplink OLTD. In addition, when the UE is in a cell forward access channel (cell facch) state, the UE may also activate uplink OLTD.

Assuming that the NodeB has activated a CPC (continuous connectivity), the CPC adopts a mode of reserving a minimum bandwidth, which can avoid a reconstruction delay caused by completely releasing a dedicated channel when a user has no service activity, and reduce control channel overhead, thereby increasing the number of users. In this state, if the current UE is in the uplink OLTD deactivation state, the UE may determine to activate the uplink OLTD.

Optionally, assuming that the UE receives RLCACK (radio link control acknowledged) of the reconfiguration response message, the UE determines that the uplink of the NodeB is synchronized according to the RLCACK, and when the UE is in the CELL _ DCH state and the NodeB has activated the CPC, if the current UE is in the state of deactivating the uplink OLTD, the UE may determine to activate the uplink OLTD.

Alternatively, assuming that the UE detects that the UE is not currently in the high-speed moving state, when the UE is in the CELL _ DCH state and the NodeB has activated the CPC, the UE may determine to activate the uplink OLTD if the UE is currently in the uplink OLTD deactivation state.

Optionally, assuming that the current UE power is not limited, neither DPCCH nor E-DPCCH may be power compressed, and uplink transmit diversity performance is not affected. Then, when the UE is in the CELL _ DCH state and the NodeB has activated the CPC, the UE may determine to activate the uplink OLTD if the current UE is in the state of deactivating the uplink OLTD.

Alternatively, assume that the UE determines that the channel quality of the serving cell exceeds some configured threshold for a sustained period of time, thereby determining that the current channel quality of the serving cell is good. Wherein, the duration (timenterval) and the threshold (threshold) may be configured by the RNC or may be set by the UE itself. When the UE is in the CELL _ DCH state and the NodeB has activated the CPC, the UE may determine to activate the uplink OLTD if the current UE is in the state of deactivating the uplink OLTD.

403. And the UE sends a notice for activating the uplink transmit diversity of the UE to the base station when determining to activate the uplink transmit diversity, or sends a notice for deactivating the uplink transmit diversity of the UE to the base station when determining to deactivate the uplink transmit diversity.

For example, when the UE determines to activate the uplink transmit diversity of the UE, the UE sends a notification to the NodeB to activate the uplink transmit diversity of the UE, and the NodeB performs corresponding adjustment according to the notification to receive data subsequently sent by the UE in the uplink transmit diversity mode. Or, when the UE determines to deactivate the uplink transmit diversity of the UE, the UE sends a notification to the NodeB to deactivate the uplink transmit diversity of the UE, and the NodeB performs corresponding adjustment according to the notification to receive data subsequently sent by the UE in a non-uplink transmit diversity manner.

The uplink transmit diversity transmission method provided by this embodiment activates/deactivates the uplink transmit diversity of the UE by the UE according to the reference measurement correlation quantity of the UE. And the UE can more timely and effectively acquire the reference measurement related quantity of the UE, so that the judgment of the activation or deactivation of the uplink transmit diversity can be more timely and effectively carried out. And then can adjust the up run transmission mode suitable for the present transmission situation in time, effectively, thus has improved the quality of the up run transmission.

Correspondingly to the previous embodiment, the embodiment of the present invention further provides a transmission method for uplink transmit diversity, including: a base station receives a notice which is sent by UE and activates the uplink transmit diversity of the UE when the UE determines to activate the uplink transmit diversity according to the reference measurement related quantity of the UE; or the base station receives a notice which is sent by the UE and used for deactivating the uplink transmit diversity of the UE when the UE determines to deactivate the uplink transmit diversity according to the reference measurement related quantity of the UE.

In an embodiment of the present invention, the transmission method for uplink transmit diversity includes:

the NodeB sends an activation request instruction to an RNC (radio network controller), so that the RNC informs the UE to activate uplink transmit diversity according to the activation request instruction; the RNC receives an activation request instruction sent by a NodeB, and informs the UE and the NodeB of activating uplink transmit diversity according to the activation request instruction; the UE receives an activation notification of activating the uplink transmit diversity of the RNC, and activates the uplink transmit diversity according to the activation notification;

and the NodeB sends a deactivation request instruction to the RNC so that the RNC informs the UE to deactivate the uplink transmit diversity according to the deactivation request instruction. The RNC receives a deactivation request instruction sent by a NodeB, informs the UE and the NodeB to deactivate the uplink transmit diversity according to the deactivation request instruction, receives a deactivation notification of the RNC for deactivating the uplink transmit diversity, and deactivates the uplink transmit diversity according to the deactivation notification.

Optionally, the NodeB sends an activation request instruction to the RNC when determining that the uplink transmit diversity of the UE needs to be activated, and sends a deactivation request instruction to the RNC when determining that the uplink transmit diversity of the UE needs to be deactivated.

Optionally, the NodeB may determine whether to activate uplink transmit diversity of the UE according to the reference measurement related quantity of the UE.

For example, the NodeB may decide to activate or deactivate uplink transmit diversity of the UE according to a preset activation condition and a reference measurement related quantity of the UE, as in the foregoing embodiments. Or, the NodeB may also detect a reference measurement related quantity of the NodeB itself, and determine to activate or deactivate uplink transmit diversity of the UE according to a preset activation condition, the reference measurement related quantity of the UE, and the reference measurement related quantity of the NodeB. The reference measurement related quantity of the NodeB includes information of resource usage in the NodeB, receiver performance, and the like.

Optionally, in this embodiment, in a deactivation request indication sent by a NodeB to an RNC, at least one of antenna information and secondary pilot information suggested by the NodeB for the RNC may be carried, where the antenna information is used to indicate that the UE suggested by the NodeB deactivates an antenna that sends a data channel after uplink transmit diversity, and specifically, the antenna information is located in a field in the deactivation indication, and the field shows a number of the antenna that sends the data channel after the UE deactivates the uplink transmit diversity or a number of an antenna that does not send the data channel after the UE deactivates the uplink transmit diversity. Assuming that two antennas of the UE are antenna 1 and antenna 2, respectively, the antenna information indicates whether to use antenna 1 to transmit a data channel or antenna 2 to transmit a data channel after the UE deactivates the transmit diversity, and in a field corresponding to the antenna information of the deactivation indication, a number 1 or 2 may be recorded to indicate that an antenna that transmits a data channel after the UE deactivates the uplink transmit diversity is antenna 1 or antenna 2, or that an antenna that does not transmit a data channel after the UE deactivates the uplink transmit diversity is antenna 1 or antenna 2.

The NodeB can determine which antenna of the UE has better channel quality according to the measurement of the secondary pilot channel, and therefore, the NodeB can propose to the RNC, through the antenna information, which antenna the UE adopts or does not adopt to transmit the data channel after deactivation in the deactivation request indication.

And the auxiliary pilot information is used for indicating the sending period of the auxiliary pilot signal after the UE suggested by the NodeB deactivates the uplink transmit diversity. The NodeB may suggest, in the deactivation request indication, the UE to deactivate the uplink transmit diversity and then to assist the transmission period of the pilot signal to the RNC.

It can be understood that, regardless of whether the NodeB suggests antenna information and secondary pilot information in the deactivation request indication, after the RNC receives the deactivation request indication, the RNC may determine the antenna information and/or the secondary pilot information for the UE, and if the NodeB suggests, the RNC may determine the antenna information and/or the secondary pilot information according to the suggestion of the NodeB and carry the antenna information and/or the secondary pilot information in the deactivation notification sent to the UE and the NodeB.

It should be noted that, after receiving the activation/deactivation indication of the NodeB, the RNC may notify the UE to activate/deactivate the uplink transmit diversity through the L3 signaling, as described in the foregoing embodiment, and when notifying the UE to activate/deactivate the uplink transmit diversity, send a corresponding acknowledgement response to the NodeB to notify the NodeB to activate/deactivate the uplink transmit diversity, or when knowing that the UE completes activating/deactivating the uplink transmit diversity, send a corresponding activation/deactivation completion notification to the NodeB to notify the NodeB to activate/deactivate the uplink transmit diversity. Of course, it is understood that the RNC may use many different messages to inform the UE and the NodeB to activate/deactivate uplink transmit diversity.

As shown in fig. 11, the embodiment may specifically implement activating or deactivating uplink transmit diversity of a UE according to the following steps, including:

501. and the RNC configures the operating parameters of the NodeB and the UE working in the uplink transmit diversity and respectively sends the uplink transmit diversity configuration parameters to the NodeB and the UE.

The uplink transmit diversity configuration parameters at least comprise a precoding feedback channel. And the NodeB and the UE receive the uplink transmit diversity configuration parameters and carry out uplink transmit diversity operation according to the configuration parameters.

502. And the NodeB determines to activate or deactivate the uplink transmit diversity of the UE.

The activating of the uplink transmit diversity of the UE may be configuring and starting the uplink transmit diversity of the UE, specifically, a state where two antennas of the UE have data channel transmission, and the deactivating of the uplink transmit diversity of the UE may be de-configuring and stopping the uplink transmit diversity of the UE, specifically, it may be understood that only one of the two antennas of the UE has a data channel transmission, the other antenna does not transmit a signal or only transmits a control channel, and the deactivated state may be a sub-state where the data channel is transmitted on the antenna 1 or the data channel is transmitted on the antenna 2.

503. The NodeB sends an activation request instruction to an RNC when determining to activate the uplink transmit diversity of the UE, or sends a deactivation request instruction to the RNC when determining to deactivate the uplink transmit diversity of the UE;

for example, the NodeB may send an activation request indication or a deactivation request indication of the uplink transmit diversity of the UE to the RNC according to the determination result in step 102. That is, the NodeB sends an activation request instruction to the RNC to activate the UE when deciding to activate the uplink transmit diversity of the UE, or the NodeB sends a deactivation request instruction to the RNC to deactivate the UE when deciding to deactivate the uplink transmit diversity of the UE.

Optionally, when the NodeB sends the deactivation instruction to the RNC, it may suggest to the RNC which antenna the UE adopts or does not adopt to send the data channel and/or the supplemental pilot signal transmission period after the deactivation. Specifically, the base station may carry, in the deactivation request indication, at least one of antenna information and auxiliary pilot information that are suggested by the base station for the RNC, where the antenna information is used to indicate an antenna that transmits a data channel after the user equipment suggested by the NodeB deactivates uplink transmit diversity, and the auxiliary pilot information is used to indicate a transmission period of an auxiliary pilot signal after the user equipment suggested by the NodeB deactivates uplink transmit diversity.

For example, the NodeB may determine which antenna has the better channel quality according to the measurement of the secondary pilot channel, and may suggest to the RNC which antenna is used or not used by the UE to transmit the data channel after the deactivation.

504. And the RNC informs the UE and the NodeB of activating the uplink transmit diversity according to the activation request indication, or informs the UE and the NodeB of deactivating the uplink transmit diversity according to the deactivation request indication.

For example, the RNC may notify the UE to activate/deactivate uplink transmit diversity through L3 signaling, where the L3 signaling message is an air-interface RRC message, such as a radio bearer reconfiguration. The RNC may notify the NodeB of activating/deactivating uplink transmit diversity by sending a corresponding acknowledgement response to the NodeB when notifying the UE of activating/deactivating uplink transmit diversity, or may notify the NodeB of activating/deactivating uplink transmit diversity by sending a corresponding activation/deactivation completion notification to the NodeB when it is known that the UE completes activating/deactivating uplink transmit diversity. Of course, it is understood that the RNC may inform the UE and the NodeB to activate/deactivate uplink transmit diversity using a variety of different messages, such as custom signaling.

For example, if the NodeB carries the antenna information of the antenna that is proposed to transmit the data channel in the deactivation indication, the RNC may notify the UE of deactivation and specify the antenna information used to transmit the data channel after deactivation in the deactivation notification according to the proposal. For example, assuming that the UE includes two antennas, antenna 1 and antenna 2, the antenna information may include at least two antenna options, such as transmitting a data channel on antenna 1 or transmitting a data channel on antenna 2. Of course, if the NodeB does not carry the antenna information of the antenna that is proposed to transmit the data channel in the deactivation indication, the RNC may also determine itself and notify the UE of deactivation in the deactivation notification and specify the antenna information used by the data channel to be transmitted after deactivation.

Optionally, the RNC may notify the NodeB and the UE of the transmission period of the secondary pilot signal in the deactivated state in the deactivation notification, so that the NodeB monitors the secondary pilot signal, and determines whether to perform uplink transmit diversity activation according to a monitoring result. Specifically, the base station determines a time point for detecting the secondary pilot signal of the user equipment according to the secondary pilot information carried by the deactivation notification message; and the base station detects the quality of the auxiliary pilot frequency of the user equipment according to the determined time point so as to determine whether to send an activation request instruction to a wireless network controller so as to activate the uplink transmit diversity of the user equipment.

In addition, before the decision of activating/deactivating the uplink transmit diversity of the UE is made, the UE and the NodeB may send the uplink transmit diversity capability, that is, the uplink transmit diversity is supported or not supported, to the RNC, so that the RNC knows that the UE and the NodeB have the capability of sending data using the uplink transmit diversity. The RNC may send uplink diversity configuration parameter information to the UE and the NodeB, respectively, after knowing that the UE and the NodeB have the capability of sending data using uplink transmit diversity, and the UE and the NodeB perform some configuration operations related to uplink transmit diversity according to the configuration parameter information.

505. And after receiving the activation or deactivation notification, the NodeB determines the resource occupation condition of a PCI (Pre-coding indication) feedback channel according to the corresponding message.

And after receiving the activation/deactivation notification, the NodeB activates or deactivates the uplink transmit diversity operation aiming at the UE according to the corresponding indication.

Optionally, if the deactivation notification is received, the NodeB should release the corresponding precoding feedback channel resource for the UE. Or, after receiving the deactivation notification, and when the RNC distributes the precoding feedback channel resource to other UEs for use, the NodeB should release the corresponding precoding feedback channel resource to the UE. Specifically, after receiving the deactivation notification, the NodeB receives a radio link management message sent by the RNC, and when the radio link management message indicates that the RNC distributes the precoding feedback channel corresponding to the UE, the NodeB releases the precoding feedback channel corresponding to the UE. And after the NodeB receives the activation notification, if the corresponding activation notification message carries the precoding feedback channel resource, using the newly allocated resource, otherwise, using the resource before deactivation, namely the resource during the previous activation. Specifically, if the activation notification message carries a precoding feedback channel, the NodeB determines the precoding feedback channel in the activation notification message as the precoding feedback channel after the UE activates uplink transmit diversity, and uses the newly allocated resource; if the activation notification message does not carry the precoding feedback channel of the UE, the NodeB determines the precoding channel configured in the previous activation as the precoding feedback channel after the UE activates the uplink transmit diversity, namely the resource before deactivation.

Optionally, if the received deactivation notification carries the related parameter sent by the secondary pilot, the NodeB detects the secondary pilot and determines activation according to the secondary pilot sending time point specified in the parameter. Specifically, the NodeB determines a time point for detecting the secondary pilot signal of the UE according to the secondary pilot information carried in the deactivation notification message; and the NodeB detects the quality of the auxiliary pilot frequency of the UE according to the determined time point so as to determine whether to send an activation request instruction to a wireless network controller to activate the uplink transmit diversity of the UE.

506. And after receiving the activation or deactivation notice, the UE determines the antenna transmitting state according to the corresponding message.

The deactivation notification is sent to the UE, and may be operated by deleting CLTD or reconfigured to a corresponding single antenna state. If the deactivation notice specifies which antenna is used for transmitting the data channel, the UE decides the antenna used for transmitting the data channel after deactivation according to the specified information.

Optionally, if the received deactivation notification carries parameters related to secondary pilot transmission, the UE transmits the secondary pilot according to the secondary pilot transmission time point specified in the parameters.

In the uplink transmit diversity transmission method provided in this embodiment, the NodeB determines to activate/deactivate uplink transmit diversity of the UE according to the reference measurement correlation quantity of the UE and instructs the RNC to notify the UE of activating/deactivating uplink transmit diversity. And the UE can be recommended to send the sending period of the antenna and/or the auxiliary pilot frequency signal used by the data channel after being deactivated, and the NodeB can more timely and effectively acquire the reference measurement related quantity of the UE, so that the judgment of the activation or deactivation of the uplink transmit diversity can be more timely and effectively carried out. And then can adjust the up run transmission mode suitable for the present transmission situation effectively in time, thus has improved the quality of the up run transmission effectively, and NodeB can release the code resource of the corresponding precoding feedback (PCI) signal channel after deactivating the up run transmit diversity, has improved the use efficiency of the code resource.
