为了便于理解，下文介绍本申请实施例涉及的通信过程。
无线资源控制(radio resource control，RRC)状态及移动性管理
目前，协议中定义了终端设备的三种RRC状态：RRC连接(RRC_connected)态、RRC空闲(RRC-idle)态和RRC非激活(RRC-inactive)态。
RRC连接态可以指终端设备完成随机接入过程之后，未进行RRC释放时所处的状态。终端设备和网络设备(例如接入网络设备)之间存在RRC连接。在RRC连接态下，终端设备可以和网络设备进行数据传输，如进行下行数据传输和/或上行数据传输。或者，终端设备也可以和网络设备进行终端设备特定的数据信道和/或控制信道的传输，以传输该终端设备的特定信息或单播信息。
在RRC连接态下，网络设备可以确定终端设备小区级别的位置信息，也就是说，网络设备可以确定终端设备所属的小区。在RRC连接态下，终端设备发生位置移动后，如从一个小区移动到另一个小区后，网络设备可以控制终端设备进行小区切换(handover)。由此可见，终端设备在RRC连接态下的移动性管理可以包括小区切换。另外，终端设备在RRC连接态下的移动性管理可以由网络设备控制，相应地，终端设备可以按照网络设备下发的指令切换到指定的小区。
RRC空闲态是指终端设备在小区中驻留，但是未进行随机接入时终端设备所处的状态。终端设备通常在开机之后，或者在RRC释放之后进入RRC空闲态。在RRC空闲态下，终端设备和网络设备(例如驻留网络设备)之间没有RRC连接，网络设备没有存储终端设备的上下文，网络设备与核心网之间没有建立针对该终端设备的连接。如果终端设备需要从RRC空闲态进入RRC连接态，则需要发起RRC连接建立过程。
在RRC空闲态下，核心网(core network，CN)可以向终端设备发送寻呼消息，也就 是说，寻呼过程可以由CN触发。可选地，寻呼区域也可以由CN配置。在一些情况下，对于处在RRC空闲态下的终端设备而言，当终端设备发生位置移动(例如，从一个小区移动到另一个小区)后，终端设备可以发起小区重选(cell reselection)过程。在另一些情况下，对于处在RRC空闲态下的终端设备而言，当终端设备需要接入小区时，终端设备可以发起小区选择(cell selection)过程。也就是说，终端设备在RRC空闲态的移动性管理可以包括小区重选和/或小区选择。
RRC非激活态是为了降低空口信令、快速恢复无线连接和快速恢复数据业务，定义的状态。RRC非激活态是处于连接态和空闲态之间的一个状态。终端设备之前已经进入了RRC连接态，然后释放了与网络设备的RRC连接，但是网络设备保存了该终端设备的上下文。另外，网络设备与核心网建立的针对该终端设备的连接没有被释放，也就是说，RAN与CN之间的用户面承载和控制面承载仍被维护，即存在CN-NR的连接。
在RRC非激活态下，RAN可以向终端设备发送寻呼消息，也就是说，寻呼过程可以由RAN触发。基于RAN的寻呼区域由RAN管理，网络设备能够知道终端设备的位置是基于RAN的寻呼区域级别的。
在一些情况下，对于处在RRC非激活态下的终端设备而言，当终端设备发生位置移动(例如，从一个小区移动到另一个小区)后，终端设备可以发起小区重选过程。在另一些情况下，对于处在RRC非激活态下的终端设备而言，当终端设备需要接入小区时，终端设备可以发起小区选择过程。也就是说，终端设备在RRC非激活态的移动性管理可以包括小区重选和/或小区选择。
无论是小区选择、小区切换还是小区重选都可以基于RRM测量的RRM测量结果进行，例如，当RRM测量结果大于RRM测量门限之后，终端设备可以执行小区选择、小区切换或者小区重选。下文介绍小区选择和小区重选的过程。
小区选择
小区选择一般发生在PLMN选择之后，旨在使得终端设备可以在选定的PLMN下尽快选择一个信号质量满足条件的小区(又称“目标小区”)进行驻留。在本申请实施例中，小区选择的对象可以称为“候选小区”。目前，小区选择可以分为初始小区选择和存储信息小区选择。
针对初始小区选择，终端设备通常没有任何先验信息可以帮助其标识具体的***频率，因此，终端设备需要根据其自身能力扫描所有的频带，以便找到一个合适的小区进行驻留。在每一个频率上，终端设备只需要搜索信号质量最好的小区，一旦发现一个合适的小区，终端设备可以选择它并进行驻留。
针对存储信息小区选择，终端设备已经在之前的接入过程中存储了载波频率相关的信息，同时也可能包括一些小区参数信息，例如，从先前收到的测量控制信息或者先前驻留/检测的小区中得到。终端设备会优先选择有相关信息的小区进行测量，一旦合适的小区出现，终端设备可以选择该小区并进行驻留。如果存储了相关信息的小区都不合适，终端设备还可以发起初始小区选择过程。
在小区选择过程中，终端设备需要对候选小区进行测量，以便进行信号质量评估，判断其是否符合驻留标准。在一些实现方式中，小区选择的测量标准可以称为S准则，当某个候选小区的信号质量满足S准则之后，便可以被选择为驻留小区。
小区重选
如上文介绍，当终端设备处于空闲态或非激活态时，可以持续地进行小区重选，以便驻留在优先级更高或信号质量更好的小区(又称“目标小区”)。在一些实现方式中，网络设备可以通过设置不同频点的优先级，来控制终端设备驻留的频点。相应地，终端设备基于频点对应的优先级选择了合适的频点之后，可以选择该频点上信号质量较好的小区，以便更好地提供服务。
在本申请实施例中，小区重选的对象可以称为“候选小区”。在一些实现方式中，候选小区可以包括邻小区列表中的小区。在另一些实现方式中，候选小区也可以包括重选过程中检测到的小区。当然，在本申请实施例中，候选小区还可以包括同频小区、异频小区、以及不同RAT的频点上的小区等等。
通常，小区重选可以分为同频小区重选和异频小区重选，同频小区重选可以解决无线覆盖的问题，而异频小区重选既可以用于解决无线覆盖的问题，也可以用于负载均衡。下文分别对针对同频小区重选和异频小区重选进行介绍。
对于同频小区重选而言，同频小区重选可以包括以下三个步骤。
步骤1，通过对比服务小区的参数与***广播中的参数确定是否启动同频测量。
在一些实现方式中，服务小区参数可以包括小区选择接收值S rxlev、小区选择质量值S qual。其中，S rxlev与S qual的确定方式可以参照S准则。
在一些实现方式中，***广播中的参数包括S intrasearchP和S intrasearchQ。
如果S rxlev＞S intrasearchP并且S qual＞S intrasearchQ，则终端设备可以选择不执行同频测量；否则，终端设备需要执行同频测量。
步骤2，对候选小区根据质量高低进行R准则排序，选择最优小区。
在一些实现方式中，R准则可以表示为：R s＝Q meas,s+Q hyst–Qoffset temp；以及R n＝Q meas,n-Qoffset–Qoffset temp。其中，R s表示服务小区的R值；R n表示邻小区的R值；Q hyst表示排序标准的滞后值；Q meas用于小区重选的RSRP值；Qoffset表示偏移值；Qoffset temp表示临时偏移值。
需要说明的是，对于同频重选而言，当***广播中存在有效的小区间Qoffset,n时，Qoffset等于小区间的Qoffset,n。当***广播中不存在有效的小区间Qoffset,n时，Qoffset等于0。对于异频重选而言，当***广播中存在有效的小区间Qoffset,n时，Qoffset等于频率间Qoffsetfrequency与小区间的Qoffset,n之和。当***广播中不存在有效的小区间Qoffset,n时，Qoffset等于频率间Qoffsetfrequency。
另外，上述R准则中“下标s”表示服务小区对应的参数，“下标n”表示邻小区对应的参数。
在一些场景中，通信***(例如，NR***)可以支持多波束操作。在进行多波束操作中的小区重选时，为判定最优小区，网络设备可以通过***消息配置等效范围(用“rangToBestCell”表示)。相应地，如果网络设备没有配置该参数，则终端设备可以重选到R排序最高的小区。相反地，终端设备将重选到R属于[R best-rangToBestCell,R best]范围且波束质量高于门限(用“absThreshSS-Consolidation”表示)数量最多的小区，其中，R best表示测量的小区中R值最高的小区。如果多个小区满足这个条件，则终端设备将重选到其中排序最高的小区。被重选的小区被认为是排序最高的小区。
在支持多波束操作的场景中，终端设备需要对波束进行测量，例如，可以通过对同步信号和物理广播信道块(synchronization signal and physical broadcast channel block，SSB)SSB或信道状态信息参考信号(channel state information-reference signal，CSI-RS)进行测量从而完成对应波束的测量。而测量过程对于终端设备而言是一个消耗能量的过程，为了降低终端设备的功耗，引入了基于SSB的测量定时配置，也称为测量定时配置(measurement timing configuration，SMTC)。SMTC定义了可用于限制终端设备对特定资源的测量的持续时间和周期。也即是说，在SMTC期间内，终端设备可以在配置的SSB或CSI-RS上进行无线资源管理测量。
需要说明的是，SMTC可以是以频带为粒度配置的。SMTC可以应用于同频小区重选和/或异频小区重选的场景中。
在一些实现方式中，小区排序及重选过程中可以满足以下的约束条件：
约束条件1，选择的小区(例如，新小区)对应的信号质量在排序中要优于当前小区， 并持续一段时间。例如，持续的时间长度大于T reseleectionNR。
约束条件2，如果终端设备处于非普通移动状态，需要考虑对参数T reseleectionNR与Q hyst进行缩放。
约束条件3，终端设备驻留源小区时间超过1s。
步骤3，根据合适小区准则确定最优小区是否为合适的小区。
在异频小区重选过程中，网络设备可以通过设置合理的优先级参数来实现不同频点的负载均衡。异频小区重选主要包括以下三个操作。
操作1，测量。
对于***信息指出的优先级高于当前频点的其他频点，终端设备需要执行对它们的测量。对于***信息指出的优先级等于或低于当前频点的其他频点，终端设备执行的测量准则如下：
如果服务小区的S rxlev>S intraSearchP且S qual>S intraSearchQ，终端设备可以选择不执行同频测量；相反地，终端设备需要启动同频测量。
如果服务小区的S rxlev>S nonintraSearchP且S qual>S nonintraSearchQ，终端设备可以选择不执行异频测量或异RAT测量；相反地，终端设备需要启动异频测量或异RAT测量。
操作2，优先级处理。
终端设备可以通过网络设备的广播消息(例如，***信息)获取频点的优先级信息(例如，公共优先级)，或者通过专用信令(例如，RRC释放消息)获取频点优先级信息(例如，专用优先级)，或者在执行inter-RAT小区(重)选择时从其他RAT继承。
在一些实现方式中，如果提供了专用优先级，终端设备可以忽略所有的公共优先级。如果***信息中没有提供终端设备当前的驻留小区的优先级信息，终端设备可以把该小区所在的频点的优先级设置为最低。
在一些实现方式中，终端设备可以只在***信息中出现的并提供了优先级的频点之间，按照优先级策略进行小区重选(尽量选择优先级高的频点)。
操作3，小区重选准则。
小区重选准则按照频点的优先级可以分为以下三种：高优先级频点的小区重选、同等优先级频点的小区重选以及低优先级的小区重选，下文针对这三种情况进行介绍。
情况1，高优先级频点的小区重选。
终端设备在当前小区驻留时间已经超过1s，小区重选到高优先级频点上的小区可以满足该小区的信号质量高于门限，并持续时间长度超过指定时间长度，此时，终端设备才可以进行小区重选。
情况2，同等优先级频点的小区重选。
对于同等优先级频点的小区重选，终端设备可以基于上文介绍的R准则对同等优先级频点上的小区进行R排序，再选择合适的小区进行驻留。详细可以参见上文介绍。
情况3，低优先级频点的小区重选。
在一些实现方式中，终端设备在当前小区驻留超过1s后，在没有高优先级频点或同等优先级频点上的小区符合要求，且当前小区的信号质量低于阈值的情况下，若低优先级频点上的小区的信号质量高于门限，且持续一定的时间，则终端设备可以进行小区重选。
需要说明的是，在上文介绍的小区重选过程中，本申请实施例对小区信号质量的计算方式不作限定。在一些实现方式中，如果***消息广播了参数N以及门限，小区信号质量可以基于满足门限的N个最优的波束对应的信号质量确定，例如，可以是N个最优的波束对应的信号质量的线形平均值。在另一些实现方式中，如果***消息未广播参数N以及门限，小区信号质量还可以是小区中波束对应的最好的信号质量，其中，N为正整数。
唤醒接收机(wake-up receiver，WUR)
为了满足终端设备的节能需求，在R18标准中计划引入WUR(又称超低功耗WUR “ultra-low power WUR，LP-WUR”)来接收节能信号(又称“唤醒信号(wake-up signal，WUS)”，“超低功耗唤醒信号(ultra-low power WUS，LP-WUS)”，低功耗唤醒信号等)。WUR具有极低成本、极低复杂度和极低功耗的特点，其主要基于包络检测的方式来接收节能信号。因此，WUR接收的节能信号与现有R16、R17标准定义的基于PDCCH承载的信号的调制方式、波形等不同。节能信号主要通过对载波信号进行ASK调制的包络信号。在一些实现方式中，包络信号的解调可基于无线射频信号提供的能量驱动低功耗电路来完成，终端设备无需供电，因此WUR可以是无源的。在另一些实现方式中，WUR也可以通过终端设备进行供电。无论哪种供电方式，WUR相比终端设备的传统接收机极大的降低了功耗。例如WUR可以实现小于1毫瓦(mw)的功耗，远低于传统接收机几十至几百mw的功耗。
目前，可以将WUR与终端设备结合在一起，作为终端设备的接收机的一个附加模块。当然，WUR也可以单独作为一个终端设备的模块，例如，实现唤醒功能。
图2是携带WUR的终端设备的示意图。参见图2，终端设备200可以包括主接收机210和WUR220。为了节约终端设备200的功耗，可以配置终端设备200处于休眠状态(例如，当终端设备处于DRX休眠期时)，或者说，终端设备的主接收机210可以处于休眠状态(参见图2(a))，此时，终端设备200可以利用WUR 220接收节能信号。在一些情况下，如果需要终端设备200唤醒主接收机210，网络设备可以通过发送唤醒信号，相应地，终端设备可以通过WUR220来监听WUS。当WUR220监听到WUS后，可以唤醒主接收机210(参见图2(b))。否则，终端设备的主接收机210可以处于休眠状态。
在一些实现方式中，上述WUR监听到WUS，可以包括：WUR监听到一个WUS，或者，WUR监听到多个WUS。
在另一些实现方式中，上述WUR唤醒主接收机，可以包括：WUR向主接收机发送WUS，WUS用于唤醒主接收机，或者，WUR向主接收机发送唤醒指示信息，唤醒指示信息用于唤醒主接收机。
为了便于区分，下文从调制方式、调制波形、传输速率、支持的带宽范围、码率等方面，介绍WUR与主接收机之间的差异。
从二者支持的调制方式来看，WUR支持的调制方式的复杂程度低于主接收机支持的调制方式的复杂程度。在一些实现方式中，WUR支持的调制方式可以包括以下调制方式中的一种或多种：幅移键控(amplitude shift keying，ASK)、相移键控(phase shift keying，PSK)、频移键控(frequency shift keying，FSK)等。相应地，主接收机支持的调制方式可以包括以下调制方式中的一种或多种：正交相移键控(quadrature phase shift keying，QPSK)、正交振幅调制(quadrature amplitude modulation，QAM)、正交频分复用(orthogonal frequency division multiplexing，OFDM)等。当然，在另一些实现方式中，主接收机也可以支持ASK、PSK、FSK中的至少之一的调制方式。本申请实施例对此不作具体限定。
从二者支持的调制波形来看，WUR支持的调制波形的复杂度低于主接收机支持的调制波形的复杂度，或者说，WUR支持的调制波形比主接收机支持的调制波形简单。例如，WUR支持的调制波形可以包括以下调制波形中的一种或多种：ASK信号对应的波形、PSK信号对应的波形、FSK信号对应的波形。相应地，主接收机支持的调制波形可以包括以下调制波形中的一种或多种：QPSK信号对应的波形、QAM信号对应的波形、OFDM信号对应的波形。当然，在一些实施例中，主接收机支持的调制波形还可以包括ASK、PSK、FSK中的一种或多种信号对应的波形。
从二者支持的传输速率来看，WUR支持的传输速率低于主接收机支持的传输速率。例如，WUR支持的传输速率小于第一速率阈值，第一速率阈值的取值可以为1Kbps至1Mbps的范围，其中，第一速率阈值的取值可以为1Kbps、128Kbps、515Kbps或1Mbps等。相应地，主接收机支持的传输速率可以大于第一速率阈。例如，主接收机支持的传输 速率可以大于10Kbps、100Kbps、1000Kbps、1Gbps等。
从二者支持的带宽范围来看，WUR支持的带宽范围小于主接收机支持的带宽范围，或者说，WUR支持的带宽比主接收机支持的带宽窄。例如，WUR支持的带宽可以小于或等于第一带宽阈值，第一带宽阈值的取值可以为1KB至1MB的范围，其中，第一带宽阈值的取值可以为1KB、128KB、515KB或1MB等。相应地，主接收机支持的带宽可以大于第一带宽阈值，例如，主接收机支持的带宽可以大于10KB、100KB、1000KB、1GB等。
从二者支持的码率来看，WUR支持的码率低于主接收机支持的码率。例如，WUR支持的码率小于或等于第一码率阈值，第一码率阈值可以在0.3至0.6之间，例如，第一码率阈值可以为0.3、0.5或0.6。相应地，主接收机支持的码率可以大于第一码率阈值。例如，主接收机支持的码率可以大于0.7、0.8、0.9或者接近于1。
基于上文的介绍可知，为了降低终端设备的功耗，引入了WUR来接收LP-WUS，如此，终端设备便可以关闭主接收机。然而，按照已有的小区选择或小区重选策略，进行小区选择或小区重选后，终端设备驻留的小区可能并不支持LP-WUS。此时，终端设备在驻留的小区无法中使用WUR，并关闭主接收机，导致终端设备的功耗依然较大。
因此，本申请实施例提供了一种无线通信的方法，在该方法中，终端设备可以接收与LP-WUS关联的第一信息，用于在小区选择或小区重选过程中选择驻留小区，有助于提高终端设备选择到支持LP-WUS的小区进行驻留的可能性，以降低终端设备的功耗。下文结合图3介绍本申请实施例的无线通信方法。
图3是本申请实施例的无线通信方法的流程图。图3所示的方法包括步骤S310。
在步骤S310中，网络设备向终端设备发送第一信息。
在一些实现方式中，第一信息用于小区重选或小区选择。或者说，终端设备可以基于第一信息执行小区选择或小区重选。
在一些实现方式中，上述第一信息可以与LP-WUS关联，或者说，第一信息可以与LP-WUS相关。例如，第一信息可以用于指示是否支持LP-WUS，其中，是否支持LP-WUS例如可以包括是否支持发送LP-WUS。或者说，上述第一信息可以与LP-WUS功能关联。例如，第一信息可以用于指示是否支持LP-WUS功能，其中，是否支持LP-WUS功能例如可以包括是否支持发送LP-WUS的功能。
在一些实现方式中，上述第一信息可以承载于***消息中，例如，第一信息可以承载于SIB1中。又例如，第一信息可以承载于SIB3中，又例如，第一信息可以承载于SIB4中。当然，在本申请实施例中，上述第一信息还可以是专用信息。本申请实施例对此不作限定。
在一些实现方式中，上述终端设备可以支持LP-WUS的终端设备，例如，可以是图2所示的终端设备。当然，在本申请实施例中，上述终端设备还可以是不支持LP-WUS的终端设备，本申请实施例对此不作限定。
如上文介绍，对于处于空闲态或非激活态的终端设备，可以通过小区选择和/或小区重选来选择合适的小区进行驻留。因此，在本申请实施例中，上述终端设备可以是处于空闲态或非激活态的终端设备。
在本申请实施例中，对第一信息针对的对象不作限定。在一些实现方式中，第一信息可以包括针对小区的信息，或者说，第一信息可以包括小区级的信息，又或者说，第一信息可以包括小区(例如，第一小区)对应的信息。其中，小区可以包括同频小区和/或异频小区。其中，同频小区可以理解为是服务小区的同频小区。异频小区可以理解为是服务小区的异频小区。
在另一些实现方式中，第一信息可以包括针对频点的信息，或者说，第一信息可以包括频点级的信息，又或者说，第一信息可以包括频点(例如，第一频点)对应的信息，其中，频点可以包括同频频点和/或异频频点。其中，同频频点可以理解为是服务小区所在频 点的同频频点。异频频点可以理解为是服务小区所在频点的异频频点。
下文以第一信息包括小区级的信息或者频点级的信息为例进行介绍。
第一信息包括小区级的信息
在一些实现方式中，第一小区对应的信息可以用于指示第一小区是否支持LP-WUS，或者，第一小区对应的信息可以用于指示第一小区是否支持LP-WUS功能。
在本申请实施例中，在小区选择或小区重选过程中引入第一小区对应的信息，有助于终端设备基于第一小区对应的信息选择到支持LP-WUS的小区作为目标小区，如此，终端设备便可以在目标小区中以低功耗接收机接收寻呼信号，以降低终端设备的功耗。
在一些实现方式中，第一小区对应的信息可以以列表的形式呈现。在一些实现方式中，若第一小区为支持LP-WUS的小区，那么列表中可以包括第一小区。也即是说，该列表中包括的小区为支持LP-WUS的小区。因此，该列表又可以称为“白名单(white list)”。如上文所述，第一小区可以为同频小区，或者说，列表中的小区为同频小区，相应地，白名单又可以称为“同频小区白名单列表”，可以用“intraFreqWhiteCellListLP-WUS”表示。当然，第一小区也可以为异频小区，或者说，列表中的小区为异频小区，相应地，白名单又可以称为“异频小区白名单列表”，可以用“inerFreqWhiteCellListLP-WUS”表示。
在另一些实现方式中，若第一小区为不支持LP-WUS的小区，那么列表中可以包括第一小区，也即是说，该列表中的小区为不支持LP-WUS的小区。因此，该列表又可以称为“黑名单(black list)”。如上文所述，第一小区可以为同频小区，或者说，列表中的小区为同频小区，相应地，黑名单又可以称为“同频小区黑名单列表”，可以用“intraFreqBlackCellListLP-WUS”表示。当然，第一小区也可以为异频小区，或者说，列表中的小区为异频小区，相应地，黑名单又可以称为“异频小区黑名单列表”，可以用“inerFreqBlackCellListLP-WUS”表示。
通常，***消息的SIB3可以用于同频小区重选，可以包括同频小区(例如，同频邻小区)信息。因此，在本申请实施例中，可以将对应同频小区的信息(例如，同频小区白名单列表和/或同频小区黑名单列表)承载于SIB3中。
下文以同频小区白名单列表，同频小区黑名单列表为例，示出了本申请实施例中SIB3实现方式。参见下文所示的SIB3的代码可以看出，在SIB3中可以携带的参数包括以下一项或多项：同频邻区列表(用“intraFreqNeighCellList”以及“intraFreqNeighCellList-v1610”表示)；同频黑名单邻区列表(用“intraFreqBlackCellList”表示)；延迟非关键扩展(用“lateNonCriticalExtension”表示)；同频白名单邻区列表(用“intraFreqWhiteCellList-r16”表示)；同频相邻CAG小区列表(用“intraFreqCAG-CellList-r16”表示)；同频小区黑名单列表(intraFreqBlackCellListLP-WUS)以及同频小区白名单列表(intraFreqWhiteCellListLP-WUS)。也即是说，可以在SIB3中携带同频小区黑名单列表(intraFreqBlackCellListLP-WUS)，以及同频小区白名单列表(intraFreqWhiteCellListLP-WUS)。

需要说明的是，在SIB3中携带小区对应的信息的实现方式有很多种，例如，上文中直接在SIB3中添加白名单列表和/或黑名单列表。当然，由于SIB3中会携带同频小区的信息，因此，在本申请实施例中还可以直接在SIB3中已包含的同频小区的信息中新增小区对应的信息，以指示该小区是否支持LP-WUS。
另外，本申请实施例中的SIB3还可以携带除上述参数之外的其他参数，本申请实施例对此不作限定。
通常，***消息的SIB4可以用于异频小区重选，可以包括异频小区(例如，异频邻小区)信息。因此，在本申请实施例中，可以将对应异频小区的信息(例如，异频小区白名单列表和/或异频小区黑名单列表)承载于SIB4中。
下文以异频小区白名单列表，异频小区黑名单列表为例，示出了本申请实施例中SIB4的实现方式。参见下文所示的SIB4的代码可以看出，在SIB4中可以携带的参数包括以下一项或多项：异频载波频率列表(用“interFreqCarrierFreqList”以及“interFreqCarrierFreqList-v1610”表示)；延迟非关键扩展(用“lateNonCriticalExtension”表示)。异频载波频率信息(用“InterFreqCarrierFreqInfo”表示)。小区重选优先级(用“cellReselectionPriority”表示)；SUL小区重选优先级(用“cellReselectionSubPriority”表示)；小区重选偏置-Q(用“q-OffsetFreq”表示)；异频邻区列表(用“interFreqNeighCellList”表示)；异频黑名单邻区列表(用“interFreqBlackCellList”表示)；异频小区黑名单列表(interFreqBlackCellListLP-WUS)，以及异频小区白名单列表(interFreqWhiteCellListLP-WUS)
上述异频载波频率信息可以包括以下中的一项或多项：下行载波频率(用“dl-CarrierFreq”表示)；频段列表(用“frequencyBandList”表示)；补充的上行链路(supplementary uplink，SUL)频段列表(用“frequencyBandListSUL”表示)；SSB数量(用“nrofSS-BlocksToAverage”表示)；门限(用“absThreshSS-BlocksConsolidation”表示)；SMTC配置(用“smtc”表示)；SSB子载波间隔(用“ssbSubcarrierSpacing”表示)；SSB测量(用“ssb-ToMeasure”表示)；用于指示SSB索引计算方式的参数(用“deriveSSB-IndexFromCell”表示)；SS的接收信号的强度指示(received signal strength Indicator，RSSI)测量(用“ss-RSSI-Measurement”表示)；小区最小接入电平(用“q-RxLevMin”表示)；SUL小区最小接入电平(用“q-RxLevMinSUL”表示)；小区最小接入质量(用“q-QualMin”表示)；终端最大发射功率(用“p-Max”表示)；小区重选时间延迟(用“t-ReselectionNR”表示)；小区重选速度因子(用“threshX-LowP”表示)；小区重选-信号质量门限(用“threshX-Q”表示)；低优先级重选门限(用“t-ReselectionNR-SF”表示)；小区重选速度因子(用“t-ReselectionNR-SF”表示)。
也即是说，在本申请实施例中，可以直接在SIB4中添加异频小区黑名单列表(interFreqBlackCellListLP-WUS)，以及异频小区白名单列表(interFreqWhiteCellListLP-WUS)。

本申请实施例还提供了一种SIB4的实现方式，需要说明的是，SIB4中包含的参数与上文介绍的SIB4中包含的参数类似，为了简洁，下文主要介绍异频小区黑名单列表以及异频小区白名单列表的携带方式。
参见下文所示的SIB4的代码可以看出，SIB4中包括异频载波频率列表(用“interFreqCarrierFreqList-v17xy”表示)。相应地，在异频载波频率列表中可以携带异频小区黑名单列表(interFreqBlackCellListLP-WUS)，以及异频小区白名单列表(interFreqWhiteCellListLP-WUS)。也即是说，在本申请实施例中，可以在SIB4中新增参数，来携带异频小区黑名单列表(interFreqBlackCellListLP-WUS)，以及异频小区白名单列表(interFreqWhiteCellListLP-WUS)。
Figure PCTCN2022129637-appb-000006
需要说明的是，在本申请实施例中，SIB4还可以携带除上述参数之外的其他参数，本申请实施例对此不作限定。
上文介绍了本申请实施例中第一小区对应的信息，下文介绍本申请实施例中第一小区对应的信息的使用方式。
在一些实现方式中，如果第一小区不支持低功耗唤醒信号，则第一小区不属于小区选择/小区重选中的候选小区，或者说，终端设备不考虑将第一小区作为候选小区。
上述第一小区不属于候选小区可以理解为在小区重选或小区选择的过程中排除第一小区，或者说，终端设备不对第一小区进行测量。当然，在本申请实施例中，终端设备也可以对第一小区进行测量，但是不将第一小区作为候选小区。
当然，在本申请实施例中，如果第一小区不支持低功耗唤醒信号，则第一小区也可以为候选小区，但是，第一小区的优先级可以低于候选小区中的支持低功耗唤醒信号的其他小区，以提高终端设备选择到支持低功耗唤醒信号的其他小区的概率。
在另一些实现方式中，如果第一小区支持低功耗唤醒信号，则第一小区属于小区选择/小区重选中的候选小区，且第一小区的优先级高于候选小区中的不支持低功耗唤醒信号的其他小区。
上述第一小区属于候选小区可以理解为在小区重选或小区选择的过程中将第一小区，作为候选小区，或者说，终端设备对第一小区进行测量。
在一些实现方式中，为了提高终端设备经过小区选择或小区重选过程后，选择到支持LP-WUS的小区作为目标小区的概率，终端设备可以在小区选择或小区重选的过程中，优先选择支持LP-WUS的小区作为目标小区。
例如，在上文介绍的小区重选过程中，终端设备可以通过R准则对候选小区进行排序，相应地，终端设备在选择目标小区时，可以将排序位置最高(例如，对应的R最大)且支持LP-WUS的小区作为目标小区。
又例如，在上文介绍的小区重选过程中，终端设备可以通过R准则对白名单中的小区进行排序，相应地，终端设备可以在选择目标小区时，可以将白名单中排序位置最高(例如，对应的R最大)的小区作为目标小区。
第一信息包括频点级的信息
在一些实现方式中，第一频点对应的信息可以用于指示第一频点是否支持LP-WUS，或者，第一频点对应的信息可以用于指示第一频点是否支持LP-WUS功能。
在本申请实施例中，通过第一频点对应的信息来指示第一频点是否支持LP-WUS，也即是说，以频点为粒度指示是否支持LP-WUS，相比于以小区为粒度指示是否支持LP-WUS的方案而言，有助于降低第一信息的传输开销。
在一些实现方式中，通信协议中规定SIB3可以用于携带同频小区的信息，因此，为了减少对通信协议的改动，若第一频点为同频频点，那么第一频点对应的信息可以承载于SIB3中。例如，可以在SIB3中新增参数，以携带第一频点对应的信息。
在另一些实现方式中，通信协议中规定SIB4可以用于携带异频小区的信息，因此，为了减少对通信协议的改动，若第一频点为异频频点，那么第一频点对应的信息可以承载于SIB4中。
例如，参见上文的SIB4对应的代码中，可以在异频频点列表(用“interFreqCarrierFreqList”表示)中，携带每个异频频点对应的信息，以指示异频频点是否支持LP-WUS。当然，在本申请实施例中，也可以直接在SIB4中新增专用的信息来指示异频频点对应的信息。本申请实施例对第一频点对应的信息在SIB4中的携带方式不作具体限定。
上文介绍了本申请实施例中第一频点对应的信息，下文介绍本申请实施例中第一频点对应的信息的使用方式。在本申请实施例中，第一频点对应的信息可以以第一频点中小区为粒度影响小区重选或小区选择过程，也可以以频点为粒度影响小区重选或小区选择过程，下文结合上述两种情况分别介绍。
在一些实现方式中，如果第一频点不支持低功耗唤醒信号，则第一频点不属于小区选择/小区重选中的候选小区，或者说，终端设备不考虑将第一频点中的小区作为候选小区。
上述第一频点中的小区不属于候选小区可以理解为在小区重选或小区选择的过程中排除第一频点，或者说，终端设备不对第一频点中的小区进行测量。当然，在本申请实施例中，终端设备也可以对第一频点中的小区进行测量，但是不将第一频点中的小区作为候选小区。
当然，在本申请实施例中，如果第一频点不支持低功耗唤醒信号，则第一频点中的小区也可以为候选小区，但是，第一频点中的小区的优先级可以低于候选小区中的支持低功耗唤醒信号的其他小区，以提高终端设备选择到支持低功耗唤醒信号的其他小区的概率。
在另一些实现方式中，如果第一频点支持低功耗唤醒信号，则第一频点中的小区属于小区选择/小区重选中的候选小区，且第一频点中的小区的优先级高于候选小区中的不支持低功耗唤醒信号的其他小区。
上述第一频点中的小区属于候选小区可以理解为在小区重选或小区选择的过程中将第一频点中的小区作为候选小区，或者说，终端设备对第一频点中的小区进行测量。
上文介绍了第一频点对应的信息以第一频点中小区为粒度影响小区重选或小区选择 过程，下文介绍第一频点的对应的信息以频点为粒度影响小区重选或小区选择过程。
在一些场景中，如上文介绍的小区重选过程中，网络设备可以通过***消息向终端设备指示频点对应的优先级(即上文涉及的“小区重选优先级”)，以便终端设备可以基于小区重选优先级选择合适的频点。因此，为了提高终端设备选择到支持LP-WUS的频点的概率，可以基于第一信息确定小区重选优先级。
在一些实现方式中，如果第一信息用于指示第一频点支持低功耗唤醒信号，则第一频点对应的小区重选优先级为最高优先级。
在本申请实施例中，将第一频点对应的小区重选优先级设置为最高优先级，有助于提高终端设备驻留在第一频点的概率，以增加LP-WUS信号的使用机会，有助于降低终端设备的功耗。
在另一些实现方式中，如果第一信息用于指示第一频点不支持低功耗唤醒信号，则第一频点对应的小区重选优先级为最低优先级。
在本申请实施例中，将第一频点对应的小区重选优先级设置为最低优先级，有助于减少终端测量或发现支持LP-WUS的小区的时间，提升终端设备重选到支持LP-WUS的小区的机会，以降低终端设备的功耗。
在一些实现方式中，可以由终端设备确定小区重选优先级，也即是说，第一频点对应的小区重选优先级可以由终端设备确定。例如，在网络设备配置了第一频点对应的重选优先级后，终端设备可以在网络设备配置的小区重选优先级的基础上，根据第一信息对第一频点的小区重选优先级进行调整，其中，调整包括提升优先级和/或降低优先级。
例如，若第一信息指示第一频点支持LP-WUS点，终端设备可以将第一频点的小区重选优先级配置为最高优先级。例如，如果服务小区所在的频点(即第一频点)支持LP-WUS，则终端设备可以将服务小区所在的频点对应的小区重选优先级调整为最高优先级。
又例如，若第一信息指示第一频点不支持LP-WUS，终端设备可以将第一频点的小区重选优先级配置为最低优先级。例如，如果服务小区所在的频点(即第一频点)不支持LP-WUS，则终端设备可以将服务小区所在的频点对应的小区重选优先级调整为最低优先级。
当然，在本申请实施例中，可以由网络设备确定小区重选优先级，也即是说，第一频点对应的小区重选优先级可以由网络设备确定，然后，网络设备将确定后的小区重选优先级指示给终端设备。例如，如果第一信息指示第一频点支持LP-WUS，则网络设备可以将第一频点对应的小区重选优先级调整为最高优先级，之后网络设备可以向终端设备指示第一频点对应的小区重选优先级为最高优先级。又例如，如果第一信息指示第一频点不支持LP-WUS，则网络设备可以将第一频点对应的小区重选优先级调整为最低优先级，之后网络设备可以向终端设备指示第一频点对应的小区重选优先级为最低优先级。
需要说明的是，上文分别以小区级的信息和频点级的第一信息为例进行了介绍。在本申请实施例中，小区级的信息与频点级的第一信息可以单独使用，也可以结合使用。例如，第一信息可以指示第一频点支持LP-WUS的情况下，指示第一频点中的那个小区支持LP-WUS。又例如，第一信息可以指示第一频点不支持LP-WUS的情况下，指示第一频点中的那个小区不支持LP-WUS。又例如，第一信息可以指示第一频点支持LP-WUS的情况下，指示第一频点中的那个小区不支持LP-WUS。又例如，第一信息可以指示第一频点不支持LP-WUS的情况下，指示第一频点中的那个小区支持LP-WUS。
