Abstract

A method for transmitting information, includes: sending a shared tracking reference signal (TRS)/channel state information-reference signal (CSI-RS), in which the shared TRS/CSI-RS is at least configured for at least one of a user equipment (UE) in an idle state and a UE in an inactive state to complete downlink synchronization and receive a paging early indication (PEI), and the PEI is carried in downlink control information (DCI). The method may also include sending first indication information, wherein the first indication information is configured for the UE to determine whether to complete the downlink synchronization and receive the PEI via the shared TRS/CSI-RS.
