Description

通信方法及装置
本申请要求于2020年06月28日提交国家知识产权局、申请号为202010600135.7、申请名称为“通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
目前，处于空闲(RRC_IDLE)态或非激活(RRC_INACTIVE)态的终端设备可以周期性地监听特定的寻呼时机(paging occasion，PO)，以确定网络设备是否对自身进行寻呼。具体地，终端设备在监听PO前，利用多个同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SSB)进行测量，并根据测量结果完成时频跟踪、定时同步等操作，以保证能够进入唤醒状态正常监听PO。由于SSB的周期较长，如20ms、40ms、160ms等，使得终端设备在监听PO前利用SSB进行测量的时间较长，从而导致终端设备的功耗较高。
现有技术中，终端设备通过系统信息(system information，SI)或寻呼消息(paging message)接收参考信号的配置信息，然后利用SSB和参考信号，或只利用参考信号完成上述测量。如此，终端设备在监听PO之前，进行测量的时间，可以由原来的多个SSB周期缩短为更少的SSB周期，如一个SSB周期，以节省终端设备的功耗。
然而，上述参考信号是当网络设备的覆盖范围内有终端设备处于连接态(RRC_CONNECTED)时，网络设备通过专用信令的方式发送给连接态的终端设备使用的。因此，若处于连接态的终端设备离开当前服务小区、或退出连接态，或其它终端设备进入当前小区、或进入连接态，参考信号可能会发生变化，则网络设备会发送新的参考信号的配置信息。当参考信号频繁变化时，处于空闲态或非激活态的终端设备会频繁接收参考信号的配置信息，从而导致终端设备功耗仍然居高不下。

又例如，二进制“00”，可以表示参考信号组1的配置信息发生变化，二进制“01”，可以表示参考信号组2的配置信息发生变化，二进制“0001”或“0100”可以表示参考信号组1和参考信号组2的配置信息均发生变化。也就是说，可以将“00”作为参考信号组1的标识，“01”作为参考信号组2的标识，参考信号组1和参考信号组2均占用2比特，不对参考信号组1和参考信号组2占用的比特位置进行限定。
当存在参考信号组3和参考信号组4时，二进制“10”，可以表示参考信号组3的配置信息发生变化，二进制“11”，可以表示参考信号组4的配置信息发生变化，则第一指示信息为二进制“0010”或“1000”时，可以表示参考信号组1和参考信号组3的配置信息发生变化，参考信号组2和参考信号组4的配置信息未发生变化；若第一指示信息为二进制“11”，可以表示参考信号组4的配置信息发生变化，参考信号组1、参考信号组2以及参考信号组3的配置信息均未发生变化。也就是说，第一指示信息可以不包括未发生变化的参考信号组的标识，第一指示信息占用的比特数可以不是固定的，与发生改变的参考信号组的个数有关。

当终端设备为第二终端设备时，支持但不使用参考信号机制的第二终端设备可以根据第二指示信息得出寻呼消息只包括参考信号的配置信息，且不包括寻呼信息，从而可以根据该第二指示信息确定不接收寻呼消息，避免该第二终端设备接收不需要的参考信号的配置信息，从而可以降低终端设备的功耗；不支持参考信号机制的第二终端设备可以不解读占用上述表1中的“00”值的第二指示信息，从而该终端设备不被指示接收只包括参考信号的配置信息的寻呼消息，可以降低终端设备的功耗。
在一种可能的设计方案中，终端设备根据指示信息确定是否接收第一消息，可以包括：终端设备根据第一指示信息和第三指示信息确定是否接收第一消息。

当终端设备为第二终端设备时，若第二指示信息占用的1比特为二进制“1”，第二终端设备可以获知寻呼消息只包括参考信号的配置信息，且不包括寻呼信息，从而可以根据该第二指示信息确定不接收寻呼消息，避免接收包括参考信号的配置信息的寻呼消息，可以降低终端设备的功耗。
或者，若第二指示信息占用的1比特为二进制“0”，第二终端设备可以获知寻呼消息包括寻呼信息，或寻呼消息包括寻呼信息和参考信号的配置信息，从而可以根据该第二指示信息确定接收寻呼消息，避免错过寻呼。
