为了描述方便,下面简单介绍本申请涉及到的术语。For the convenience of description, the following briefly introduces the terms involved in this application.
1、寻呼(paging)1. Paging
寻呼是指网络可以通过寻呼消息联系处于无线资源控制(radio resource control,RRC)空闲状态(idle state)或RRC非激活状态(inactive state)下的终端设备以及可以通过短消息接收系统消息变更、地震和海啸预警系统指示信息。寻呼消息和短消息通过寻呼无线网络临时标识(paging-radio network temporary identity,P-RNTI)加扰并且承载在物理下行控制信道(physical downlink control channel,PDCCH)或物理下行共享信道(physical downlink shared channel,PDSCH)上发送。Paging means that the network can contact terminal devices in radio resource control (radio resource control, RRC) idle state or RRC inactive state (inactive state) through paging messages, and can receive system message changes through short messages. , Earthquake and tsunami warning system instruction information. Paging messages and short messages are scrambled by the paging-radio network temporary identity (P-RNTI) and carried on the physical downlink control channel (PDCCH) or physical downlink shared channel (physical downlink). shared channel, PDSCH).
2、非连续接收(discontinuous reception,DRX)2. Discontinuous reception (DRX)
处于空闲状态的终端设备监听核心网(core network,CN)发起的paging,处于非激活状态的终端设备监听无线接入网(radio access network,RAN)发起的paging时,终端设备不需要连续的监听承载寻呼消息的信道,即终端设备使用非连续接收(DRX)机制来监听寻呼消息。在使用DRX时,处于RRC idle state或RRC inactive state的终端设备在一个DRX周期内只在一个Paging机会监听寻呼消息。其中,DRX周期是由网络设备为终端设备配置的。When the terminal equipment in the idle state listens to the paging initiated by the core network (CN), and the terminal equipment in the inactive state listens to the paging initiated by the radio access network (RAN), the terminal equipment does not need to continuously monitor The channel that carries the paging message, that is, the terminal device uses the discontinuous reception (DRX) mechanism to monitor the paging message. When using DRX, a terminal device in the RRC idle state or RRC inactive state only monitors paging messages at one Paging opportunity in a DRX cycle. Among them, the DRX cycle is configured by the network device for the terminal device.
3、信道状态测量的测量放松状态3. Measurement relaxation state of channel state measurement
终端设备在未进入测量放松状态时,需要测量服务小区的信道状态且每M个DRX周期评估至少一次服务小区的小区选择S准则,该小区选择S准则用于判断选择小区的条件是否满足,其中,M为大于0的整数。例如,终端设备通过测量服务小区发送的同步信号或参考信号得到信道状态的测量值,并且每M个DRX周期对至少两个测量值进行滤波得到服务小区的信道状态的评估值,其中,该至少两个测量值至少间隔DRX周期的一半。终端设备再根据该信道状态的评估值确定小区选择S准则是否满足。该测量值和该评估值都可以反映该服务小区的信道状态,或者,该信道状态包括该测量值和/或评估值。When the terminal device does not enter the measurement relaxed state, it needs to measure the channel state of the serving cell and evaluate the cell selection S criterion of the serving cell at least once every M DRX cycle. The cell selection S criterion is used to determine whether the conditions for selecting a cell are met, where , M is an integer greater than 0. For example, the terminal device obtains the measurement value of the channel state by measuring the synchronization signal or the reference signal sent by the serving cell, and filters at least two measurement values every M DRX cycles to obtain the evaluation value of the channel state of the serving cell, where the at least The two measured values are separated by at least half of the DRX cycle. The terminal equipment then determines whether the cell selection S criterion is satisfied according to the estimated value of the channel state. Both the measurement value and the evaluation value may reflect the channel state of the serving cell, or the channel state includes the measurement value and/or the evaluation value.
为了进一步降低终端设备因测量带来的功耗,一种放松测量方法被提出,终端设备在使用该放松测量方法时,可以称为处于放松测量状态或测量放松状态。进入测量放松状态的终端设备在N*M个DRX周期(或者说整数倍个DRX周期)内进行一次服务小区信道状态的测量或评估,或者,进行至少两次测量且进行一次评估,以达到节省终端设备功耗的目的,其中,N为大于1的整数。测量放松状态的时间长度可以由网络设备预先配置,例如,N*M个DRX周期。在一种实现方法中,终端设备在进入测量放松状态时启动计时 器,该计时器的时长为N*M个DRX周期,且计时器运行期间终端设备不测量服务小区的信道状态。当计时器超时时,终端设备测量服务小区的信道状态,若满足测量放松的条件,则保持或进入测量放松状态,否则,退出测量放松状态。In order to further reduce the power consumption of the terminal device due to measurement, a relaxation measurement method is proposed. When the terminal device uses the relaxation measurement method, it can be said to be in a relaxation measurement state or a measurement relaxation state. The terminal equipment that enters the measurement relaxed state performs a measurement or evaluation of the channel state of the serving cell within N*M DRX cycles (or integer multiples of DRX cycles), or performs at least two measurements and performs an evaluation to achieve savings The purpose of terminal equipment power consumption, where N is an integer greater than 1. The length of time for measuring the relaxed state may be pre-configured by the network device, for example, N*M DRX cycles. In one implementation method, the terminal device starts a timer when it enters the measurement relaxed state, the duration of the timer is N*M DRX cycles, and the terminal device does not measure the channel state of the serving cell during the running of the timer. When the timer expires, the terminal device measures the channel state of the serving cell, and if the measurement relaxation condition is met, it maintains or enters the measurement relaxation state, otherwise, it exits the measurement relaxation state.
由于终端设备移动的不确定性,例如,终端设备在一段时间内处于位移较小的状态或静止状态,此时终端设备进入服务小区的测量放松状态。若终端设备突然开始移动,却仍然保持测量放松状态,则可能会导致终端设备因无法及时进行服务小区测量而延迟终端设备进行小区选择或重选,进而影响终端设备通信质量。本申请提出处于测量放松状态的终端设备,通过检测用于接收寻呼消息或系统消息的第一信号,确定第一信号的第一值,再根据该第一值确定是否退出测量放松状态,以实现及时退出测量放松状态,及时进行服务小区信道状态测量,保证终端设备正常进行小区选择或重选,提高终端设备通信可靠性的目的。Due to the uncertainty of the movement of the terminal device, for example, the terminal device is in a state of small displacement or a static state for a period of time, and at this time the terminal device enters the measurement relaxed state of the serving cell. If the terminal device suddenly starts to move but still maintains a measurement relaxed state, it may cause the terminal device to delay cell selection or reselection due to the inability of the terminal device to perform the serving cell measurement in time, thereby affecting the communication quality of the terminal device. This application proposes that a terminal device in the measurement relaxation state determines the first value of the first signal by detecting the first signal used to receive paging messages or system messages, and then determines whether to exit the measurement relaxation state according to the first value, to Realize the purpose of exiting the measurement relaxed state in time, and measuring the channel state of the serving cell in time, ensuring that the terminal equipment normally performs cell selection or reselection, and improving the communication reliability of the terminal equipment.

S210,终端设备进入服务小区信道状态测量的测量放松状态。S210: The terminal device enters the measurement relaxed state of the channel state measurement of the serving cell.
终端设备在未进入测量放松状态时,需要测量服务小区的信道状态且每M个DRX周期评估至少一次服务小区的小区选择S准则,该小区选择S准则用于判断选择小区的条件是否满足。终端设备需要对至少两个信道状态的测量值进行滤波得到评估值,该至少两个测量值至少间隔DRX周期的一半。When the terminal device does not enter the measurement relaxed state, it needs to measure the channel state of the serving cell and evaluate the cell selection S criterion of the serving cell at least once every M DRX cycles. The cell selection S criterion is used to determine whether the conditions for selecting a cell are met. The terminal device needs to filter at least two channel state measurement values to obtain an evaluation value, and the at least two measurement values are separated by at least half of the DRX cycle.
终端设备测量服务小区信道状态,终端设备根据信道状态的测量值确定进入服务小区信道状态测量的测量放松状态。The terminal device measures the channel state of the serving cell, and the terminal device determines to enter the measurement relaxed state of the channel state measurement of the serving cell according to the measured value of the channel state.
例如图3所示,终端设备在未进入测量放松状态时,其正常测量服务小区的信道状态,即在每个DRX周期T内测量一次网络设备发送的同步信号或参考信号得到测量值。也就是说,终端设备以T为周期进行信道状态测量。终端设备根据信道状态测量的结果进入测量放松状态,在第一时间间隔内不测量信道状态,即延长信道状态测量的周期。例如,图3中该第一时间间隔是近4个DRX周期,即终端设备在T测量后至5T间不进行信道状态测量,也即终端设备在T、5T、9T(图中未示出)等进行信道状态测量,测量周期由测量放松前的T变更为4T。For example, as shown in Figure 3, when the terminal device does not enter the measurement relaxed state, it normally measures the channel state of the serving cell, that is, measures the synchronization signal or reference signal sent by the network device once in each DRX cycle T to obtain the measurement value. In other words, the terminal equipment performs channel state measurement with a period of T. The terminal device enters the measurement relaxed state according to the result of the channel state measurement, and does not measure the channel state in the first time interval, that is, extends the period of the channel state measurement. For example, the first time interval in Figure 3 is nearly 4 DRX cycles, that is, the terminal device does not perform channel state measurement after T measurement to 5T, that is, the terminal device is at T, 5T, 9T (not shown in the figure) Wait for the channel state measurement, the measurement period is changed from T before the measurement relaxation to 4T.
S220,网络设备向终端设备发送第一信号。S220: The network device sends the first signal to the terminal device.
该终端设备从该网络设备接收该第一信号,作为示例而非限定,第一信号可以为以下一种或多种:The terminal device receives the first signal from the network device. As an example and not limitation, the first signal may be one or more of the following:

其中,该PDCCH可以用于承载调度寻呼消息的DCI,或者,该PDCCH可以用于承载调度系统消息的DCI。该PDSCH可以用于承载寻呼消息,或者,该PDSCH可以用于承载系统消息,但本申请不限于此。Wherein, the PDCCH may be used to carry the DCI of the scheduling paging message, or the PDCCH may be used to carry the DCI of the scheduling system message. The PDSCH can be used to carry paging messages, or the PDSCH can be used to carry system messages, but the application is not limited thereto.
根据本申请的方案,进入测量放松状态的终端设备放松测量能够反映信道状态的信号(例如,同步信号或参考信号),但可以通过接收到的上述与寻呼消息和/或系统消息有关的第一信号来估计服务小区的信道状态,确定是否退出测量放松状态,在通过第一信号估计信道状态变差的情况下退出测量放松状态,能够及时地测量服务小区的信道状态,以提高通信的可靠性。According to the solution of the present application, a terminal device that enters a relaxed state for measurement relaxes a signal that can reflect the channel state (for example, a synchronization signal or a reference signal), but can pass the received first paging message and/or system message. Use one signal to estimate the channel state of the serving cell, determine whether to exit the measurement relaxation state, and exit the measurement relaxation state when the channel state is estimated to be worse through the first signal, so that the channel state of the serving cell can be measured in time to improve the reliability of communication sex.
S230,终端设备确定第一信号的第一值。S230: The terminal device determines the first value of the first signal.
该第一值可以是终端设备测量第一信号得到的测量值,也可以是根据第一信号的测量值计算得到的第一信号的评估值,或是通过其他方法确定的、能够反映第一信号强弱或能够反映信道状态的评估值,本申请对第一值的确定方法及手段不作限定,例如,第一信号的测量值通过滤波运算得到第一信号的评估值。The first value can be a measurement value obtained by the terminal device measuring the first signal, or an evaluation value of the first signal calculated based on the measurement value of the first signal, or it can be determined by other methods and can reflect the first signal. The strength or the evaluation value that can reflect the channel state, this application does not limit the method and means for determining the first value, for example, the evaluation value of the first signal is obtained by the measurement value of the first signal through filtering operation.
作为示例非限定,该第一值为以下参数值中的一种或多种:该第一信号的重复接收次数、参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal receiving quality,RSRQ)、接收信号强度指示(received signal strength indication,RSSI)、信号与干扰加噪声比(signal to interference plus noise ratio,SINR)、信噪比(signal noise ratio,SNR)、成功检测重复次数、覆盖增强等级、下行无线链路误块率、以特定误块率可靠接收假设的PDCCH的链路水平。As an example and non-limiting, the first value is one or more of the following parameter values: the number of repeated receptions of the first signal, reference signal receiving power (RSRP), reference signal receiving quality (reference signal) receiving quality, RSRQ), received signal strength indication (RSSI), signal to interference plus noise ratio (SINR), signal noise ratio (SNR), successful detection repetition The number of times, coverage enhancement level, downlink radio link block error rate, and the link level at which the hypothetical PDCCH can be reliably received with a specific block error rate.
该第一值可以称为第一信号的测量值、第一信号的评估值、信道状态估计值、状态值或参数值,本申请对此不作限定。The first value may be referred to as a measurement value of the first signal, an evaluation value of the first signal, a channel state estimation value, a state value, or a parameter value, which is not limited in this application.
S240,终端设备根据该第一值确定将检测服务小区的信道状态的周期由第一周期变更为第二周期,其中,所述第二周期小于所述第一周期。S240: The terminal device determines according to the first value to change the period of detecting the channel state of the serving cell from the first period to the second period, where the second period is smaller than the first period.
也就是说,终端设备根据第一值确定以更小的周期进行信道状态测量。具体的,终端设备进入服务小区信道状态测量的测量放松状态前,按第二周期进行信道状态测量。终端设备进入服务小区信道状态测量的测量放松状态后,按第一周期进行信道状态测量,由于第一周期大于第二周期,能够减少终端设备进行测量的次数,进而降低终端设备的功耗。例如,第二周期为M个DRX周期,第一周期为N*M个DRX周期,其中M为大于0的整数,N为大于1的整数。终端设备在测量放松状态减少了测量的次数,但终端设备不能及时确定信道状态,为了终端设备能够估计信道状态,本申请中,终端设备可以通过检测与寻呼消息系统消息有关的信号来估计服务小区的信道状态,进而确定是否退出测量放松状态。根据本申请的方案,进入测量放松状态的终端设备放松测量能够反映信道状态的信号(例如,同步信号或参考信号),但可以通过与寻呼消息或系统消息有关的第一信号(例如,承载DCI的PDCCH、承载寻呼消息或系统消息的PDSCH、第一DMRS或第二DMRS)的第一值来估计服务小区的信道状态,确定是否退出测量放松状态,在通过第一信号估计信道状态变差的情况下,及时退出测量放松状态,减小测量服务小区的信道状态的周期,及时获取信道状态信息,以提高通信的可靠性。例如,通过用于承载调度寻呼消息或系统消息的DCI的PDCCH、用于承载寻呼消息或系统消息的PDSCH、用于接收上述PDCCH的DMRS或用于接收上述PDSCH的DMRS中的一种或多种信号的第一值来估计服务小区的信道状态,以便终端设备能够及时退出测量放松状态,进而及时进行服务小区的信道状态测量,以保证终端设备通信的可靠性。In other words, the terminal device determines to perform channel state measurement in a smaller cycle according to the first value. Specifically, before the terminal device enters the measurement relaxed state of the channel state measurement of the serving cell, the channel state measurement is performed in the second cycle. After the terminal device enters the measurement relaxed state of the channel state measurement of the serving cell, the channel state measurement is performed according to the first period. Since the first period is greater than the second period, the number of measurements performed by the terminal device can be reduced, thereby reducing the power consumption of the terminal device. For example, the second cycle is M DRX cycles, and the first cycle is N*M DRX cycles, where M is an integer greater than 0, and N is an integer greater than 1. The terminal device reduces the number of measurements in the relaxed state of measurement, but the terminal device cannot determine the channel state in time. In order for the terminal device to estimate the channel state, in this application, the terminal device can estimate the service by detecting the signal related to the paging message system message The channel state of the cell, and then determine whether to exit the measurement relaxed state. According to the solution of the present application, the terminal device that enters the measurement relaxed state relaxes the signal (for example, synchronization signal or reference signal) that can reflect the channel state, but can pass the first signal related to the paging message or system message (for example, bearer The first value of the PDCCH of the DCI, the PDSCH that carries the paging message or the system message, the first DMRS or the second DMRS) is used to estimate the channel state of the serving cell, determine whether to exit the measurement relaxation state, and use the first signal to estimate the channel state change. In the case of bad conditions, exit the measurement relaxed state in time, reduce the period of measuring the channel state of the serving cell, and obtain channel state information in time to improve the reliability of communication. For example, through one of the PDCCH used to carry DCI for scheduling paging messages or system messages, the PDSCH used to carry paging messages or system messages, the DMRS used to receive the above-mentioned PDCCH, or the DMRS used to receive the above-mentioned PDSCH, or The first values of various signals are used to estimate the channel state of the serving cell, so that the terminal device can exit the measurement relaxed state in time, and then perform the channel state measurement of the serving cell in time to ensure the reliability of the communication of the terminal device.
终端设备确定第一值后,比较第一值与第一门限值的大小,和/或,比较第一值与参考值的差值和第二门限值大小,根据比较的结果确定是否退出测量放松状态,或者说根据比较的结果确定是否将测量信道状态的周期由第一周期变更为第二周期。其中,参考值可以是终端设备上一次测量第一信号得到的第一值,也就是说,终端设备上一次接收第一信号得到的第一值。或者该参考值可以是网络设备发送给终端设备的或终端设备中预配置的,但本申请不限于此。After determining the first value, the terminal device compares the first value with the first threshold value, and/or compares the difference between the first value and the reference value with the second threshold value, and determines whether to exit according to the comparison result Measure the relaxed state, or determine whether to change the period of measuring the channel state from the first period to the second period according to the result of the comparison. The reference value may be the first value obtained by the terminal device last time measuring the first signal, that is, the first value obtained by the terminal device last time receiving the first signal. Or the reference value may be sent by the network device to the terminal device or pre-configured in the terminal device, but the present application is not limited to this.
作为示例非限定,该第二周期可以是DRX周期,也可以是网络设备发送给终端设备 的在非测量放松状态测量信道状态的周期。As an example and not limitation, the second period may be a DRX period, or a period for measuring the channel state in a non-measurement relaxed state sent by the network device to the terminal device.
一种实施方式中,该第一值为终端设备成功检测到该第一信号所需要的重复次数(记作成功检测重复次数)。网络设备通过重复发送的方式来发送该第一信号,即网络设备连续重复发送该第一信号,终端设备可以根据成功检测到该第一信号所需要的重复次数来确定是否退出测量放松状态。In one embodiment, the first value is the number of repetitions required for the terminal device to successfully detect the first signal (denoted as the number of repetitions of successful detection). The network device sends the first signal in a repeated sending manner, that is, the network device continuously sends the first signal repeatedly, and the terminal device can determine whether to exit the measurement relaxation state according to the number of repetitions required to successfully detect the first signal.
本申请中,退出测量放松状态可以理解为测量信道状态的周期由第一周期变更为第二周期。In this application, exiting the measurement relaxed state can be understood as changing the period of measuring the channel state from the first period to the second period.
例如,网络设备重复发送第一信号,终端设备在该DRX周期内检测一次就成功检测到第一信号,则该第一值为1,也就是说,终端设备成功检测到该第一信号所需要的重复次数为1;若终端设备检测两次才成功检测到第一信号,则该第一值为2;若终端设备检测三次才成功检测到第一信号,则该第一值为3。若终端设备检测第一信号的次数达到网络设备重复发送第一信号的最大次数时仍未成功检测到第一信号,则终端设备确定检测第一信号失败,终端设备确定未获取有效的第一值,进而不进行是否退出测量放松状态的判断。For example, if the network device repeatedly sends the first signal, and the terminal device successfully detects the first signal once in the DRX cycle, the first value is 1, that is, the terminal device successfully detects the first signal. The number of repetitions is 1; if the terminal device detects the first signal after two detections, the first value is 2; if the terminal device detects the first signal after three detections, the first value is 3. If the terminal device detects the first signal for the maximum number of times that the network device repeatedly sends the first signal and fails to detect the first signal, the terminal device determines that the detection of the first signal fails, and the terminal device determines that it has not acquired a valid first value , And then do not judge whether to exit the measurement relaxed state.
终端设备检测到第一信号并确定成功检测重复次数后,可以通过以下三种方式确定是否退出测量放松状态,或者说通过以下三种方式确定是否将测量信道状态的周期由第一周期变更为第二周期,其中,第一周期大于第二周期。需要说明的是,以下三种方式仅为举例,在具体实现中终端设备可以根据第一值和第一门限值来确定是否退出测量放松状态,或者确定是否变更测量信道状态的周期。After the terminal device detects the first signal and determines the number of successful detection repetitions, it can determine whether to exit the measurement relaxation state by the following three methods, or determine whether to change the period of measuring the channel state from the first period to the first period by the following three methods: Two cycles, where the first cycle is greater than the second cycle. It should be noted that the following three methods are only examples. In specific implementation, the terminal device may determine whether to exit the measurement relaxed state or determine whether to change the period of measuring the channel state according to the first value and the first threshold value.
方式一method one
如果成功检测重复次数大于或等于第一门限值,则终端设备确定退出测量放松状态,将测量信道状态的周期由第一周期变更为第二周期。终端设备进入测量放松状态后,在第一周期内测量一次服务小区的信道状态,检测至少两次第一信号,若检测到第一信号且确定出成功检测重复次数,如果成功检测重复次数大于或等于第一门限值,则确定退出测量放松状态,将测量服务小区的信道状态的周期由第一周期变更为第二周期,其中,第一周期大于第二周期。If the number of successful detection repetitions is greater than or equal to the first threshold, the terminal device determines to exit the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period. After the terminal device enters the measurement relaxed state, it measures the channel state of the serving cell once in the first cycle, and detects the first signal at least twice. If the first signal is detected and the number of successful detection repetitions is determined, if the number of successful detection repetitions is greater than or If it is equal to the first threshold value, it is determined to exit the measurement relaxed state, and the period for measuring the channel state of the serving cell is changed from the first period to the second period, where the first period is greater than the second period.
根据本申请的方案,当成功检测重复次数大于或等于第一门限值时,终端设备退出测量放松状态,开始以较小的周期对服务小区进行信道状态测量,能够降低终端设备因信道状态突发变化而没有及时进行小区重选的概率,进而提高终端设备通信的可靠性。According to the solution of the present application, when the number of successful detection repetitions is greater than or equal to the first threshold, the terminal device exits the measurement relaxed state and starts to measure the channel state of the serving cell in a smaller period, which can reduce the sudden change of the terminal device due to the channel state. The probability of changing without timely cell reselection, thereby improving the reliability of terminal equipment communication.
在一种可能实施方式中,第一信号为第一PDCCH,该第一PDCCH用于承载调度寻呼消息的DCI。终端设备通过成功接收或解码该第一PDCCH的重复次数确定是否退出信道状态测量的测量放松状态。以图4为例,终端设备在0时刻测量服务小区的信道状态,并确定进入测量放松状态。之后,终端设备按7T为周期进行服务小区的信道状态测量,即从0时刻测量后开始到7T测量前的第一时间间隔内的六次测量机会不测量服务小区的信道状态。终端设备在每个DRX周期内监听一次寻呼消息,若网络设备发送寻呼消息或P-RNTI加扰的PDCCH,该寻呼消息或该PDCCH可能不是针对该终端设备发送的,该终端设备可能会检测到用于解码该PDCCH的DMRS,并且可能解调出该PDCCH,若该PDCCH调度了寻呼消息,该终端设备可以解码出寻呼消息。这时,终端设备可以根据以下(1)至(4)中的一种或多种信号的成功检测重复次数确定是否退出测量放松状态:In a possible implementation manner, the first signal is a first PDCCH, and the first PDCCH is used to carry DCI for scheduling paging messages. The terminal device determines whether to exit the measurement relaxation state of the channel state measurement by successfully receiving or decoding the number of repetitions of the first PDCCH. Taking Figure 4 as an example, the terminal device measures the channel state of the serving cell at time 0 and determines to enter the measurement relaxed state. After that, the terminal device performs the channel state measurement of the serving cell on a 7T cycle, that is, the channel state of the serving cell is not measured for six measurement opportunities in the first time interval from the measurement at time 0 to the first time before the 7T measurement. The terminal device monitors a paging message once in each DRX cycle. If the network device sends a paging message or PDCCH scrambled by P-RNTI, the paging message or the PDCCH may not be sent for the terminal device, and the terminal device may The DMRS used to decode the PDCCH is detected, and the PDCCH may be demodulated. If the PDCCH schedules a paging message, the terminal device can decode the paging message. At this time, the terminal device can determine whether to exit the measurement relaxation state according to the number of successful detection repetitions of one or more of the following signals (1) to (4):
(1)成功解析出用于解码该PDCCH的第一DMRS所需要的重复次数,或者(1) Successfully parse out the number of repetitions required to decode the first DMRS of the PDCCH, or
(2)成功解码出该PDCCH所需要的重复次数,或者(2) The number of repetitions required to successfully decode the PDCCH, or
(3)成功解析出用于解码承载寻呼消息的PDSCH的第二DMRS所需要的重复次数,或者(3) Successfully parse out the number of repetitions required to decode the second DMRS of the PDSCH carrying the paging message, or
(4)成功解码出承载寻呼消息的PDSCH所需要的重复次数。(4) The number of repetitions required to successfully decode the PDSCH carrying the paging message.
如图4所示,终端设备在T与2T之间、5T与6T之间检测到网络设备发送的P-RNTI加扰的PDCCH或寻呼消息。例如,网络设备发送第一信号的重复次数为3,终端设备在T与2T之间成功检测第一信号所需要的重复次数(即第一值)小于第一门限值,如第一门限值为2,终端设备成功检测第一信号所需要的重复次数(即第一值)为1,则终端设备保持测量放松状态。网络设备在2T与3T、3T与4T、4T与5T之间没有发送寻呼消息或P-RNTI加扰的PDCCH,或终端设备在上述时间内没有检测到寻呼消息或P-RNTI加扰的PDCCH,则终端设备不进行测量或不需要确定成功检测重复次数(即第一值),终端设备可以认为此时没有有效的成功检测重复次数,即没有有效的第一值,终端设备不将该第一值与第一门限值进行比较,终端设备保持测量放松状态。在5T与6T之间,网络设备发送第一信号,且终端设备检测到第一信号,并确定第一信号的第一值,例如,第一值为成功检测重复次数,若第一值大于或等于第一门限值,如第一门限值为2,终端设备在5T与6T之间成功检测第一信号所需要的重复次数为3,即第一值为3,则第一值大于第一门限值,此时终端设备退出测量放松状态,开始进行信道状态测量。例如,终端设备在6T之后开始按DRX周期进行信道状态测量,即终端设备将测量信道状态的周期由7T变更为T。测量信道状态的时间间隔为第二周期,该第二周期可以是T,也可以是由网络设备为终端设备预配置的退出测量放松状态后测量信道状态的时间间隔。终端设备在退出测量放松状态后以第二周期周期性地测量服务小区信道状态,可选地,该周期可以是终端设备进入测量放松状态前测量信道状态的周期。需要说明的是,图4以第一信号在时间资源上被重复多次发送作为示例进行说明,第一信号还可以是在频率资源上被重复多次发送,或者时频资源或空域资源上重复发送多次,本申请对此不作限定。As shown in FIG. 4, the terminal device detects the PDCCH or paging message scrambled by the P-RNTI sent by the network device between T and 2T, and between 5T and 6T. For example, the number of repetitions of the first signal sent by the network device is 3, and the number of repetitions (ie, the first value) required for the terminal device to successfully detect the first signal between T and 2T is less than the first threshold, such as the first threshold The value is 2, and the number of repetitions (ie, the first value) required for the terminal device to successfully detect the first signal is 1, and the terminal device maintains the measurement relaxed state. The network equipment does not send paging messages or P-RNTI scrambled PDCCH between 2T and 3T, 3T and 4T, 4T and 5T, or the terminal equipment does not detect a paging message or P-RNTI scrambled within the above time PDCCH, the terminal device does not perform measurement or does not need to determine the number of successful detection repetitions (ie the first value). The terminal device can consider that there is no valid number of successful detection repetitions at this time, that is, there is no valid first value. The first value is compared with the first threshold value, and the terminal device keeps the measurement relaxed state. Between 5T and 6T, the network device sends the first signal, and the terminal device detects the first signal and determines the first value of the first signal. For example, the first value is the number of successful detection repetitions. If the first value is greater than or Equal to the first threshold value. If the first threshold value is 2, the number of repetitions required for the terminal device to successfully detect the first signal between 5T and 6T is 3, that is, the first value is 3, and the first value is greater than the first value. A threshold value. At this time, the terminal device exits the measurement relaxation state and starts to perform channel state measurement. For example, the terminal device starts to perform channel state measurement according to the DRX cycle after 6T, that is, the terminal device changes the period of measuring the channel state from 7T to T. The time interval for measuring the channel state is the second period, and the second period may be T, or the time interval for measuring the channel state after exiting the measurement relaxed state pre-configured by the network device for the terminal device. The terminal device periodically measures the channel state of the serving cell in a second period after exiting the measurement relaxed state. Optionally, the period may be a period for the terminal device to measure the channel state before entering the measurement relaxed state. It should be noted that FIG. 4 takes as an example the first signal being repeatedly sent multiple times on time resources. The first signal may also be repeatedly sent multiple times on frequency resources, or repeated on time-frequency resources or spatial resources. Send multiple times, this application is not limited.
在另一种可能的实施方式中,该第一信号为承载系统消息的第二PDSCH,该系统消息可以是在寻呼消息指示系统消息变更的情况下终端设备接收到的系统消息,本申请不限于此。终端设备进入测量放松状态后以较长的周期测量信道状态,根据成功接收到第二PDSCH所需要的重复次数(记作成功检测重复次数)确定是否退出测量放松状态,在成功检测重复次数大于或等于第一门限值的情况下,终端设备退出测量放松状态,将测量信道状态的周期由第一周期变更为第二周期。In another possible implementation manner, the first signal is a second PDSCH carrying system messages, and the system messages may be system messages received by the terminal device when the paging message indicates the system message change. This application does not Limited to this. After the terminal device enters the measurement relaxation state, it measures the channel state in a longer period, and determines whether to exit the measurement relaxation state according to the number of repetitions required to successfully receive the second PDSCH (recorded as the number of successful detection repetitions). When it is equal to the first threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period.
方式二Way two
在成功检测该第一信号所需要的重复次数(记作成功检测重复次数)与成功检测重复次数的参考值的差值大于或等于第二门限值的情况下,终端设备确定退出测量放松状态,将测量信道状态的周期由第一周期变更为第二周期。该参考值可以是终端设备上一次确定的成功检测第一信号所需要的重复次数,或者,该参考值可以由网络设备发送给终端设备或终端设备预配置的值。In the case that the difference between the number of repetitions required to successfully detect the first signal (denoted as the number of repetitions of successful detection) and the reference value of the number of repetitions of successful detection is greater than or equal to the second threshold value, the terminal device determines to exit the measurement relaxation state , Change the period of measuring the channel state from the first period to the second period. The reference value may be the number of repetitions required for successfully detecting the first signal determined last time by the terminal device, or the reference value may be sent by the network device to the terminal device or a pre-configured value of the terminal device.
根据本申请的方案,终端设备根据第一信号的第一值与参考值的差值确定是否退出测量放松状态,即该差值大于或等于第二门限值的情况下,退出测量放松状态,能够降低终端设备因信道状态突发变化而没有及时进行小区重选的概率,能够提高终端设备通信的可 靠性。According to the solution of the present application, the terminal device determines whether to exit the measurement relaxation state according to the difference between the first value of the first signal and the reference value, that is, when the difference is greater than or equal to the second threshold value, exit the measurement relaxation state, It can reduce the probability that the terminal device does not perform cell reselection in time due to sudden changes in the channel state, and can improve the reliability of the communication of the terminal device.
例如,第一信号为第一PDSCH,即第一信号为承载寻呼消息的PDSCH。终端设备确定成功检测(或接收)该第一PDSCH所需要的重复次数(记作成功检测重复次数),并确定该成功检测重复次数与参考值的差值,在该差值大于或等于第二门限值的情况下,终端设备退出测量放松状态,将测量信道状态的周期由第一周期变更为第二周期。以图4为例,图4中的第一信号为承载寻呼消息的第一PDSCH,终端设备在0时刻根据测量的信道状态确定进入测量放松状态。终端设备在T与2T之间成功接收到第一PDSCH,并且确定成功接收该第一PDSCH所需要的重复次数(记作成功检测重复次数)为X。终端设备确定该成功检测重复次数X与参考值Y的差值|X-Y|小于第二门限值,终端设备保持测量放松状态。而在5T与6T之间终端设备再次成功接收到第一PDSCH,且确定成功检测重复次数Z与参数值Y的差值|Z-Y|大于或等于第二门限值,终端设备退出测量放松状态,将测量信道状态的周期由第一周期变更为第二周期。也就是说,终端设备在退出测量放松状态后开始以T为周期测量服务小区的信道状态,即该第二周期为T,第二周期也可以由网络设备发送给终端设备。可选地,该周期可以是终端设备进入测量放松状态前测量信道状态的周期。在本示例中,该参考值可以为终端设备进入测量放松状态后第一次确定的第一信号的第一值,该参考值还可以是网络设备发送给终端设备的值或终端设备预配置的值。或者,该参考值为上一次确定的第一信号的第一值。For example, the first signal is the first PDSCH, that is, the first signal is the PDSCH that carries the paging message. The terminal device determines the number of repetitions required to successfully detect (or receive) the first PDSCH (denoted as the number of repetitions of successful detection), and determines the difference between the number of repetitions of successful detection and the reference value, where the difference is greater than or equal to the second In the case of the threshold value, the terminal device exits the measurement relaxed state, and changes the period of measuring the channel state from the first period to the second period. Taking FIG. 4 as an example, the first signal in FIG. 4 is the first PDSCH carrying the paging message, and the terminal device determines to enter the measurement relaxed state according to the measured channel state at time 0. The terminal device successfully receives the first PDSCH between T and 2T, and determines that the number of repetitions required to successfully receive the first PDSCH (denoted as the number of repetitions for successful detection) is X. The terminal device determines that the difference |X-Y| between the number of successful detection repetitions X and the reference value Y is less than the second threshold value, and the terminal device maintains the measurement relaxed state. However, between 5T and 6T, the terminal device successfully receives the first PDSCH again, and determines that the difference between the number of successful detection repetitions Z and the parameter value Y |ZY| is greater than or equal to the second threshold, and the terminal device exits the measurement relaxed state, The period for measuring the channel state is changed from the first period to the second period. That is, the terminal device starts to measure the channel state of the serving cell with a period T after exiting the measurement relaxed state, that is, the second period is T, and the second period may also be sent by the network device to the terminal device. Optionally, the period may be the period for measuring the channel state before the terminal device enters the measurement relaxed state. In this example, the reference value may be the first value of the first signal determined for the first time after the terminal device enters the measurement relaxed state, and the reference value may also be a value sent by the network device to the terminal device or a value pre-configured by the terminal device. value. Or, the reference value is the first value of the first signal determined last time.

例如图5所示,该第一信号为用于解调第一PDCCH的DMRS(即第一DMRS的一例),终端设备在0时刻根据信道状态测量确定进入测量放松状态,在7T时刻之前不测量服务小区的信道状态。终端设备在每个DRX周期监听寻呼消息,终端设备根据接收到的第一信号确定第一信号的第一值,并根据第一值确定是否退出测量放松状态,例如该第一值为RSRP值。For example, as shown in Figure 5, the first signal is a DMRS used to demodulate the first PDCCH (that is, an example of the first DMRS). The terminal device determines to enter the measurement relaxed state according to the channel state measurement at time 0, and does not measure before time 7T.
