本公开实施例涉及的执行主体包括但不限于：支持蜂窝移动通信的手机终端等UE，以及基站等。
本公开实施例的一个应用场景为，相关技术中，空闲态UE和非激活态UE可以共享连接态UE使用TRS/CSI-RS配置，即空闲态UE和非激活态UE可以使用空想的TRS/CSI-RS。
连接态UE使用TRS/CSI-RS实际面向小区或者一组UE，因此TRS/CSI-RS配置不会考虑和PO之间的关系。
相关技术中，UE在非小区中心是，可以通过接收3个周期的SSB来进 行精同步；
如果UE知道有配置的TRS/CSI RS，那么可以通过一个周期的SSB来同步。
PEI会引入，PEI可能基于DCI，其位置由基站配置，位于PO前面1-3个SSB可以配。
如图2所示，本示例性实施例提供一种信息传输方法，信息传输方法可以应用于蜂窝移动通信系统的基站中，包括：
步骤201：发送共享TRS/CSI-RS，其中，所述共享TRS/CSI-RS至少被配置为供空闲态的用户设备UE和/或非激活态的UE完成下行同步并接收PEI，其中，所述PEI携带于DCI中。
这里，UE可以是采用蜂窝移动通信技术进行无线通信的手机终端等。基站可以是在蜂窝移动通信系统中，向UE提供接入网接口的通信设备。
TRS/CSI-RS可以用于供UE获取信道的状态、波束管理、移动性管理和速率匹配等。
基站和UE物理晶振的频率是会有小小的偏差的，不可能做到完全一致，这使得UE接收到的射频载波信号会有相位上的偏差，在接收子载波的解调符号星座图上，表现为相位上的旋转，即接收的调制符号偏离了一定的相位角度，这是由于频偏在时间上的积累造成的。这个时候，需要跟踪参考信号(tracking reference signal，TRS)来追踪其它数据信号的旋转相位。TRS是一种多周期的TRS/CSI-RS，确切的说是一个4-1端口，3个TRS/CSI-RS密度，位于连续两个时隙的NZP-TRS/CSI-RS，在一个时隙内时间上两个TRS最小间隔是4个OFDM符号，频域上间隔4个子载波。可以根据TRS来估算频率和时间上的误差。接收数据补偿这些误差，即可旋回原始发送的调制坐标位置。

共享的TRS/CSI-RS通常位于一个SSB周期内。UE可以在一个SSB周期内完成下行同步。
PEI和共享的TRS/CSI-RS的时域位置可以灵活配置，可以将PEI配置到与共享的TRS/CSI-RS较近的位置，如此，可以缩短UE的苏醒时间，在完成基于共享的TRS/CSI-RS的下行同步后，在较短时间内就可以接收PEI。进而减小由于UE苏醒时间较长带来的功耗增加。
如此，通过共享的TRS/CSI-RS完成下行同步并接收基站发送的PEI。一方面，UE在可以利用TRS/CSI-RS完成下行同步并接收PEI，不再需要三个SSB周期进行下行同步，减小同步功耗。另一方面，基站可以灵活配置PEI和共享的TRS/CSI-RS的时域位置，缩短UE从进行下行同步到接收PEI的苏醒时间，进而减小UE功耗，提高待机时长。

第一指示信息指示第一值时，UE采用共享的TRS/CSI-RS做同步，并基于该同步并接收PEI。
第一指示信息指示第二值时，UE可以采用相关技术中的方法，采用SSB进行同步，并基于SSB完成的同步并接收PEI。
在一个实施例中，所述方法还包括：
在所述共享TRS/CSI-RS关联的同步信号块SSB周期内，发送所述PEI。
基站在配置PEI时，可以将PEI配置到时域上与共享的TRS/CSI-RS接近的位置。例如，可以将PEI配置到时域上与共享的TRS/CSI-RS接近的 SSB周期内。
如此，UE在通过共享的TRS/CSI-RS完成同步后，可以在较短的时间内接收PEI，从而减少UE的苏醒时间，降低UE功耗。
