为便于更好的理解本申请实施例，对本申请相关的NR寻呼过程进行说明。
NR的寻呼消息是周期性向终端发送的，监听寻呼消息的位置为寻呼时机(paging occasion，PO)。用户的PO位置与用户标识(Identity，ID)相关，不同的用户的PO离散分散在寻呼周期之内，如图2所示。
为便于更好的理解本申请实施例，对本申请相关的非连续接收(Discontinuous Reception，DRX)进行说明。
出于终端节电的考虑，LTE中引入DRX传输机制。在没有数据传输的时候，可以通过停止接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)(此时会停止PDCCH盲检)来降低功耗，从而提升电池使用时间。DRX的基本机制是为处于RRC连接态的终端设备配置一个DRX周期(cycle)。如图3所示，DRX cycle由“激活期(On Duration)”和“休眠期(Opportunity for DRX)”组成：在“On Duration”时间内，终端设备监听并接收PDCCH(激活期)；在“Opportunity for DRX”时间内，终端设备不接收PDCCH以减少功耗(休眠期)。另外寻呼消息的传输也是一种RRC空闲态的DRX机制，此时DRX周期为寻呼消息的周期。从图3可以看出，在时域上，时间被划分成一个个连续的DRX Cycle。
为便于更好的理解本申请实施例，对本申请相关的终端节能机制进行说明。
由于终端处于连接态的能耗占NR终端能耗的绝大部分，因此NR版本16(release16，Rel-16)节能信号也是用于终端处于RRC连接状态时的节能。
传统的终端节能机制主要为DRX。当配置DRX时，终端在DRX ON Duration监听PDCCH，若ON Duration期间收到数据调度，则终端基于DRX定时器的控制持续监听PDCCH直至数据传输完毕；否则若终端在DRX ON Duration未收到数据调度，则终端进入DRX(非连续接收)以实现节能。可见，DRX是一种以DRX周期为时间颗粒度的节能控制机制，因此不能实现最优化功耗控制。比如即使终端没有数据调度，终端在周期性启动DRX ON Duration定时器运行期间也要监听PDCCH，因此依然存在功率浪费的情况。
为了实现终端进一步的节能，NR节能增强引入了节能信号。节能信号与DRX机制结合使用。其具体的技术原理是，终端在DRX ON Duration之前接收节能信号的指示。如图4所示，当终端在一个DRX周期有数据传输时，节能信号“唤醒”终端，以在DRX ON Duration期间监听PDCCH；否则，当终端在一个DRX周期没有数据传输时，节能信号不“唤醒”终端，终端在DRX ON Duration期间不需要监听PDCCH。相比现有DRX机制，在终端没有数据传输时，终端可省略DRX ON Duration期间PDCCH监听，从而实现节能。终端在DRX ON Duration之前的时间被称为非激活时间。终端在DRX ON Duration的时间被称为非激活时间。
Rel-16的节能技术主要针对处于RRC连接状态的终端，且针对DRX机制进行了节能优化。
然而，当终端处于RRC空闲(idle)或RRC去激活(inactive)状态时，终端需要根据寻呼消息的周期持续的监听寻呼消息，但终端只是偶然才有业务从而被寻呼到，因此终端大部分时间对寻呼消息的监听并没有对应的寻呼消息，这客观上存在功耗优化的空间，即如何在终端没有寻呼消息时避免节能寻呼消息，从而实现节能。
基于上述问题，本申请提出了一种寻呼指示方案，能够实现接收寻呼消息时的节能。
以下通过具体实施例详述本申请的技术方案。
图5是根据本申请实施例的无线通信的方法200的示意性流程图，如图5所示，该方法200可以包括如下内容中的至少部分内容：
S210，网络设备发送指示信息，其中，该指示信息用于指示是否监听寻呼消息，和/或，该指示信息用于指示可用的参考信号；
S220，终端设备接收该指示信息。
在本申请实施例中，该终端设备可以根据该指示信息，确定是否监听寻呼消息，和/或，获取该可用的参考信号。
可选地，该终端设备处于空闲态或者去激活态。或者，该终端设备处于RRC空闲(idle)或RRC去激活(inactive)状态。
可选地，该可用的参考信号用于该终端设备在接收寻呼消息时的时频同步和/或无线资源管理(Radio Resource Management，RRM)测量。也即，该终端设备在获取该可用的参考信号之后，可以基于该可用的参考信号，在接收寻呼消息时进行时频同步和/或RRM测量。从而提升接收寻呼消息的效率。
可选地，该可用的参考信号包括但不限于以下至少一种：
跟踪参考信号(Tracking reference signal，TRS)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)。
例如，该可用的参考信号为网络设备为处于RRC连接态终端配置的用于时频同步的参考信号，处于RRC空闲(idle)或RRC去激活(inactive)状态的终端设备基于该指示信息获取该可用的参考信号(CSI-RS/TRS)，终端设备在接收寻呼消息之前除了采用同步信号/物理广播信道块 (synchronization signal/physical broadcast channel block，SS/PBCH block)进行时频同步，也可以同时采用可用的参考信号，如CSI-RS/TRS来实现时频同步。由此，终端设备有望在较短的时间内利用足够的参考信号(CSI-RS和/或SSB)来实施时频同步，因此可以实现终端节能。
可选地，该可用的参考信号包括多个参考信号中可用的参考信号，该多个参考信号的配置信息(如参考信号的时域位置)为网络设备通过系统信息或RRC信令配置的。
例如，网络设备通过系统信息或RRC信令配置参考信号1、参考信号2、参考信号3、参考信号4、参考信号5和参考信号6。以及网络设备通过指示信息所对应的信息域中的6比特指示可用的参考信号，其中，6比特中的每一比特对应一个参考信号，6比特中比特取值为1则指示对应的参考信号可用，比特取值为0则指示对应的参考信号不可用，或反之。
也即，该网络设备可以通过该指示信息从该多个参考信号中指示该可用的参考信号。避免直接指示该可用的参考信号所带来的信令开销。
可选地，该指示信息可以是寻呼提前指示(paging early indication，PEI)信息。当然，该指示信息也可以是其他类型的信息，本申请对此并不限定。
PEI信息可以在终端设备接收寻呼消息的PO位置之前发送，当终端设备没有寻呼消息时，PEI信息指示终端设备没有寻呼消息，或指示终端设备不接收寻呼消息，即不接收调度寻呼消息的PDCCH。而反之，在终端设备有寻呼消息需要接收时，PEI信息指示终端设备有寻呼消息，或指示终端设备接收寻呼消息，即接收调度寻呼消息的PDCCH。
需要说明的是，当终端设备处于RRC空闲(idle)或RRC去激活(inactive)状态时，终端设备仅需要在PO之内监听寻呼消息，PO通常对应一个时隙或数个符号，因此PO时间相对很短。因此，直接在PO之前发送节能信号，相当于是用节能信号代替PO内的寻呼的接收，因此未必能带来终端的节能增益。然而，当终端设备在接收寻呼消息之前还需要基于同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)进行时频同步，因此，终端设备在PO之前，一般需要提前数个同步信号块(Synchronization Signal Block，SSB)周期开始进行时频同步操作，如上述图2所示，假设终端设备的寻呼接收的位置为图2中的PO 5位置，为执行同步操作，终端设备可能需要接收PO5之前的SSB1、SSB2以及SSB3。
因此，若终端设备实际上在PO没有寻呼消息，网络设备若可以提前数个SSB周期发送PEI，则可以使得终端设备避免执行同步操作，如下图6所示为例，若网络设备指示终端设备没有寻呼消息，假设终端设备的寻呼接收的位置为图6中PO 5的位置，则终端设备可节省对SSB1、SSB2、SSB3的接收和处理。这样，终端可以实现较为可观的节能。
对于处于RRC idle或RRC inactive状态的NR终端设备，在接收系统消息或者寻呼消息之前，只能采用SS/PBCH block实现时频同步，但由于SS/PBCH block的周期较大，至少在5ms，典型值为10ms或者20ms，这样，终端设备在接收系统消息或寻呼消息之前，需要提前几十甚至上百毫秒(ms)进行SS/PBCH block的接收以进行时频同步操作，因此终端设备在接收系统消息或者寻呼消息之前需要提前几十甚至上百毫秒(ms)醒来做时频同步操作，这样终端设备在接收系统消息或者寻呼消息时的功耗较大。例如如图7所示，终端设备在接收寻呼消息之前，需要接收3个SSB周期的SSB，以进行时频同步，假设SS/PBCH block的周期为20ms，即终端设备需要提前60毫秒(ms)进行SS/PBCH block的接收以进行时频同步操作。
而另一方面，网络设备对于处于RRC连接态(connected state)的终端设备可发送CSI-RS或TRS，对于不同的终端设备可以发送不同的CSI-RS信号，若这些CSI-RS可以为处于RRC idle或RRC inactive状态的NR终端设备所用，则可以增加处于RRC idle或RRC inactive状态的NR终端设备的可用的参考信号，从而潜在地可以减少终端实现时频同步所需的时间，进而实现终端节能。例如，如图8所示，若终端设备在接收寻呼消息之前除了采用SSB进行时频同步，也可以同时采用参考信号，如CSI-RS/TRS来实现时频同步。由此，终端设备有望在较短的时间内利用足够的参考信号(CSI-RS和/或SSB)来实施时频同步，因此可以实现终端节能。
再一方面，网络设备中可能存在大量处于RRC idle或RRC inactive的终端，不同终端的PO分布在不同的时间位置，因此要满足不同终端需求，需要在对应不同终端的PO的时间位置上发送PEI信息。因此，发送PEI信息不可避免带来了网络开销问题。针对NR系统，由于需要指示多波束的波速扫描，因此，还需要支持PEI信息的波束扫描发送，这更加剧了PEI信息发送带来的开销问题。
需要说明的是，版本15(release15，Rel-15)和版本16(release16，Rel-16)在用于调度系统信息的下行控制信息(Downlink Control Information，DCI)格式1_0中有15比特的预留比特(Reserved bits)。可见，DCI格式1_0用于调度系统信息时，DCI还依然有15个比特为预留比特，这些预留比 特不承载调度信息。此外，调度系统信息的PDCCH也是周期性发送的。以调度剩余系统信息(Remaining System Information，RMSI)(SIB1)的PDCCH为例。当SSB与控制资源集(Control Resource Set，CORESET)0的复用图样为图样1(即SSB与CORESET0为时分复用)时，调度系统信息块(System Information Block，SIB)的PDCCH的搜索空间的周期为2个无线帧，即20ms。当SSB与CORESET0的复用图样为图样2或3(即SSB与CORESET0为频分复用)时，调度SIB的PDCCH的搜索空间的周期等于SSB的周期，而SSB的周期为5ms、10ms、20ms……160ms，而通常用于初始接入的小区的SSB的周期为20ms。再者，调度系统信息的PDCCH为了能覆盖完整的NR小区，也支持波束扫描的方式发送。且发送系统信息的波束数量和波束宽度通常与发送寻呼消息的波束数量和波束宽度均一致。
可见，综合上述因素，周期性发送的调度系统信息的PDCCH提供了承载PEI信息的绝佳选择。本申请实施例可以复用用于调度系统信息的DCI格式1_0中的预留比特来承载PEI信息，也即，赋予了用于调度系统信息的DCI格式1_0中的预留比特新的含义或用途，以承载PEI信息。
可选地，在一些实施例中，该指示信息(如PEI信息)可以承载于用于调度系统信息的DCI中。例如，该指示信息占用该用于调度系统信息的DCI的预留比特的部分比特或者全部比特。其中，该预留比特不用于调度系统信息。
其中，该用于调度系统信息的DCI为DCI格式1_0，DCI格式1_0的循环冗余码校验(Cyclical Redundancy Check，CRC)由系统信息无线网络临时标识符(System Information Radio Network Temporary Identity，SI-RNTI)加扰。
可选地，在一些实施例中，携带该指示信息(如PEI信息)的PDCCH也可以是调度寻呼消息的PDCCH，即承载的DCI的CRC校验比特由P-RNTI加扰的PDCCH。此种情况下，该指示信息(如PEI信息)可以承载于用于调度寻呼消息的DCI中。例如，该指示信息占用该用于调度寻呼消息的DCI的预留比特的部分比特或者全部比特。其中，该预留比特不用于调度寻呼消息。
作为是一个示例，可以使用位置在前的PO上调度寻呼的PDCCH来承载位置在后的PO所对应的PEI信息，PO以及PEI信息之间的位置关系可以是预设的或配置的。如图9所示，PO1上调度寻呼消息的PDCCH携带PEI 1，该PEI 1用于指示PO4上是否监听寻呼消息；PO2上调度寻呼消息的PDCCH携带PEI 2，该PEI 2用于指示PO5上是否监听寻呼消息；PO3上调度寻呼消息的PDCCH携带PEI 3，该PEI 3用于指示PO6上是否监听寻呼消息。
可选地，在一些实施例中，携带该指示信息(如PEI信息)的PDCCH也可以专门配置的专用于携带该指示信息的PDCCH。该专用于携带该指示信息的PDCCH的搜索空间、CORESET可由网络设备通过系统信息或RRC信令配置。
可选地，该指示信息(如PEI信息)所占用的比特位置和/或比特数量为预配置或协议约定的，或者，该指示信息(如PEI信息)所占用的比特位置和/或比特数量为网络设备配置的。
可选地，该系统信息包括但不限于以下中的至少一种：

例如图10所示，该指示信息(如PEI信息)承载于用于调度SIB1的DCI中，该DCI由PDCCH携带，PEI信息共计占用8个比特，其中8个比特的前4个比特对应PO3，用于指示PO3上终端或终端组中的终端是否监听寻呼消息；后4个比特对应PO4，用于指示PO4上终端或终端组中的终端是否监听寻呼消息。而前/后4比特中的每一个比特分别对应所对应PO上的4个终端组，分别记为：终端组1、终端组2、终端组3、终端组4。
可选地，该指示信息所占用的比特所满足的对应关系为预配置或协议约定的，或者，该指示信息所占用的比特所满足的对应关系为网络设备通过RRC信令或广播信令配置的。该对应关系例如可以是指示信息所占用的比特与终端之间的对应关系，也可以是指示信息所占用的比特与终端组之间的对应关系，也可以是指示信息所占用的比特与寻呼帧之间的对应关系，也可以是指示信息所占用的比特与寻呼时机之间的对应关系，还可以是指示信息所占用的比特与寻呼时机和终端或终端组之间的对应关系。
在一些实施例中，该终端组通过以下方式进行划分：
基于终端标识确定终端分组的索引；或者，
基于终端的接入等级确定终端分组的索引。
例如，采用终端标识(UE ID)对X取模，X为分组的总数目，取模所得的结果为终端分组的索引。
又例如，采用终端标识(UE ID)经过第一处理后所得结果确定终端分组的索引；或者，采用终端标识(UE ID)经过第一处理后所得结果再对X取模，X为分组的总数目，取模所得的结果为终端分组的索引；其中，该第一处理为终端标识(UE ID)除以Y，或者，该第一处理为终端标识(UE ID)除以Y所得结果向下取整，Y为一个寻呼周期内的PO数量。
再例如，基于终端的接入等级(access class)进行分组，如接入等级与终端分组的索引一一对应。
可选地，在一些实施例中，携带该DCI(承载有该指示信息)的PDCCH与该指示信息所指示的寻呼时机之间的对应关系为预配置或协议约定的，或者，携带该DCI(承载有该指示信息)的PDCCH与该指示信息所指示的寻呼时机之间的对应关系为网络设备配置的。例如，如图11所示，携带该指示信息(如PEI信息)的PDCCH 1对应PO3和PO4，携带该指示信息(如PEI信息)的PDCCH 2对应PO5和PO6。
可选地，携带该DCI(承载有该指示信息)的PDCCH与该指示信息所指示的寻呼时机之间的对应关系包括以下至少一种：
该PDCCH的监听时机(PDCCH monitoring occasion)与该指示信息所指示的寻呼时机之间的时间间隔或最小时间间隔；
该PDCCH所对应的寻呼时机的数量。
可选地，该PDCCH的监听时机与该指示信息所指示的寻呼时机之间的时间间隔或最小时间间隔，包括以下之一：
该PDCCH的监听时机与该指示信息所指示的寻呼时机之间的时间间隔或最小时间间隔；
该PDCCH的监听时机与该指示信息所指示的第一个寻呼时机之间的时间间隔或最小时间间隔；
该PDCCH的监听时机与该指示信息所指示的寻呼时机所在的无线帧之间的时间间隔或最小时间间隔；
该PDCCH所在的无线帧与该指示信息所指示的寻呼时机所在的无线帧之间的时间间隔或最小时间间隔。
需要说明的是，该PDCCH的监听时机与该指示信息所指示的寻呼时机之间的时间间隔或最小时间间隔，具体可以是：该PDCCH的监听时机的起始符号或结束符号与该指示信息所指示的寻呼时机 的起始时间或者起始位置之间的时间间隔或最小时间间隔。该PDCCH的监听时机与该指示信息所指示的第一个寻呼时机之间的时间间隔或最小时间间隔，具体可以是：该PDCCH的监听时机的起始符号或结束符号与该指示信息所指示的第一个寻呼时机的起始时间或者起始位置之间的时间间隔或最小时间间隔。该PDCCH的监听时机与该指示信息所指示的寻呼时机所在的无线帧之间的时间间隔或最小时间间隔，具体可以是：该PDCCH的监听时机的起始符号或结束符号与该指示信息所指示的寻呼时机所在的无线帧之间的时间间隔或最小时间间隔。
例如，该指示信息指示一个寻呼时机，此种情况下，该PDCCH的监听时机与该指示信息所指示的寻呼时机之间的时间间隔，具体指：该PDCCH的监听时机与该指示信息所指示的一个寻呼时机之间的时间间隔。具体的，终端设备可以基于寻呼时机(PO)的起始时间位置，再往前推算该时间间隔得到时间点t，承载终端设备的PEI信息的PDCCH的监听时机应为时间点t之前最近的PDCCH监听时机。
再例如，该指示信息指示多个寻呼时机，此种情况下，该PDCCH的监听时机与该指示信息所指示的寻呼时机之间的时间间隔，具体指：该PDCCH的监听时机与该指示信息所指示的第一个寻呼时机之间的时间间隔，此时，可以根据携带该指示信息的PDCCH对应的寻呼时机的数量确定其他对应的寻呼时机。如图11所示，携带PEI信息的PDCCH1与其指示的第一个PO间隔20ms，若对应的PO数量为2，则其指示的20ms之后PO3和PO4。具体的，终端设备可以基于第一个PO的起始时间位置，再往前推算该时间间隔得到时间点t，承载终端设备的PEI信息的PDCCH的监听时机应为时间点t之前最近的PDCCH监听时机。
再例如，在某些配置情况下，该PDCCH的监听时机与该指示信息所指示的寻呼时机之间时间间隔，或该PDCCH所在的无线帧与该指示信息所指示的寻呼时机之间时间间隔，或该PDCCH的监听时机与该指示信息所指示的第一个寻呼时机之间的时间间隔，或该PDCCH所在的无线帧与该指示信息所指示的寻呼时机所在的无线帧之间时间间隔，可能不是一个固定的数值，而随着该PDCCH所在的监听时机变化而变化，例如由于时分双工(Time Division Duplex，TDD)系统中上下行配置导致的不同的时间段内PO的分布可能是不均匀的。在这种情况下，可以采用最小时间间隔进行约束，即该PDCCH的监听时机与该指示信息所指示的寻呼时机之间时间间隔，或该PDCCH所在的无线帧与该指示信息所指示的寻呼时机之间时间间隔，或该PDCCH的监听时机与该指示信息所指示的第一个寻呼时机之间的时间间隔，或该PDCCH所在的无线帧与该指示信息所指示的寻呼时机所在的无线帧之间时间间隔，不小于该最小时间间隔。该最小时间间隔可以是网络设备配置的，也可以是预定义的。在这种情况下，终端设备基于接收寻呼消息的PO时间位置以及该最小时间间隔确认该PDCCH的监听时机。一般是基于PO的起始时间位置，再往前推算最小时间间隔得到时间点t，承载终端的PEI信息的该PDCCH的监听时机应为时间点t之前最近的PDCCH监听时机。需要说明的是，由于NR系统中，调度系统信息的PDCCH监听时机位于类型0(type0)PDCCH搜索空间中，而出于波束扫描的需求，在每一个type0PDCCH搜索空间周期中可能会包括多个PDCCH监听时机，这种情况下，终端设备基于下述准则之一确定PDCCH监听时机：1)所确定的PDCCH监听时机是位于时间点t之前的最近的监听时间(有可能仅包含一个type0PDCCH搜索空间周期中的部分PDCCH监听时机)；2)所确定的PDCCH监听时机是位于时间点t之前最近且包含一个type0PDCCH搜索空间周期中所有的PDCCH监听时机的type0PDCCH搜索空间周期中的PDCCH监听时机。
例如，如图12所示，PDCCH(携带承载有PEI信息的DCI)的监听时机与PEI信息所指示的寻呼时机(PO)之间需满足最小时间间隔。因此对于PO5，其所对应的PDCCH监听时机位于图12中的PDCCH1；而对于PO6，其所对应的PDCCH监听时机位于图12中的PDCCH 2。
又例如，如图13所示，PDCCH(携带承载有PEI信息的DCI)的监听时机与PEI信息所指示的寻呼时机(PO)之间需满足最小时间间隔。因此对于PO5，其所对应的PDCCH监听时机位于图13中的PDCCH1；而对于PO6，其所对应的PDCCH监听时机位于图13中的PDCCH 2。
而当每一个type0PDCCH搜索空间周期中会包括多个PDCCH监听时机时，如图14所示，每一个type0PDCCH搜索空间周期中会包括2个PDCCH监听时机，对于PO5，当采用上述第一种准则时，PO5的起始时间位置，再往前推算最小时间间隔得到时间点t，承载终端的PEI信息的该PDCCH的监听时机应为时间点t之前最近的PDCCH监听时机，即所确定的PDCCH监听时机为对应的PDCCH2中的PDCCH 2-1；而当采用第二种准则时，PO5的起始时间位置，再往前推算最小时间间隔得到时间点t，承载终端的PEI信息的该PDCCH的监听时机应为时间点t之前最近且包括2个PDCCH监听时机的一个type0PDCCH搜索空间周期的PDCCH监听时机，即所确定的PDCCH监听时机为对应的PDCCH 1中的PDCCH 1-1和PDCCH 1-2。
因此，所确定的承载PEI信息的PDCCH监听时机与寻呼时机(PO)之间满足一定的时间间隔或 最小时间间隔，使得终端设备在有寻呼消息需要接收时，可以在所述一定的时间间隔或最小时间间隔内接收到足够数量的SSB，从而取得时频同步。
可选地，该PDCCH所对应的寻呼时机的数量是根据该PDCCH的周期确定的。
例如，如图11所示，一个携带PEI信息的PDCCH对应2个PO；该数目也可以基于PDCCH的周期确定。例如调度SIB1的PDCCH的周期为20ms，则一个调度SIB1且携带PEI的PDCCH可以对应20ms之内所包含的PO数目。
这里需要说明的是，当SSB与CORESET 0的复用图样为图样1(即SSB与CORESET0为时分复用)时，调度系统信息块(System Information Block，SIB)的PDCCH的搜索空间的周期为2个无线帧，即20ms。当SSB与CORESET0的复用图样为图样2或3(即SSB与CORESET0为频分复用)时，调度SIB的PDCCH的搜索空间的周期等于SSB的周期，而SSB的周期为5ms、10ms、20ms……160ms，而通常用于初始接入的小区的SSB的周期为20ms。因此，基于SSB与CORESET0的复用图样，调度系统信息的PDCCH的搜索空间的周期可能不同。另一方面，一个调度系统信息的PDCCH所对应的寻呼时机的数量也会因为寻呼时机的配置而变化，例如若调度寻呼消息的PDCCCH搜索空间所配置的PDCCH监听时刻在时间域上分布密集，则一个PDCCH所对应的寻呼时机的数量会较多；反之，若调度寻呼消息的PDCCCH搜索空间所配置的PDCCH监听时刻在时间域上分布稀疏，则一个PDCCH所对应的寻呼时机的数量会较少。进一步地，NR TDD系统中，不同的调度系统信息的PDCCH周期的PDCCH所对应的寻呼时机的数量也可能不同，这是由于不同的调度系统信息的PDCCH周期内由于TDD上下行配置在不同的调度系统信息的PDCCH周期内可能不同，导致不同的调度系统信息的PDCCH周期内实际分布的PO数量不同。
因此，在本申请实施例中，可以借助于用于调度系统信息的DCI中的预留比特来携带指示信息(如PEI信息)，用于指示是否监听寻呼消息，从而在终端不需要接收寻呼消息时避免在PO位置上监听寻呼进而实现节能。和/或，当终端设备处于RRC idle态或RRC inactive态时，网络设备可以向终端设备指示可用的参考信号，辅助终端用于在接收寻呼消息前的时频同步，从而也实现终端节能，亦提升通信性能。
进一步地，本申请实施例的技术方案复用现有的DCI中的预留比特，还不增加网络的发送指示信息(如PEI信息)的资源开销和网络功耗。从而提升网络效率。
