A method for a user equipment (UE) to monitor paging messages is provided. The method monitors, while the UE is in an Idle mode, a physical paging channel (PPCH) for receiving paging messages associated with the UE from a serving radio access network (RAN). The method receives one or more paging messages associated with the UE while monitoring the PPCH. The method then determines, whether the one or more paging messages are received during a small data transmission (SDT) procedure. The method further determines whether to terminate the SDT procedure or not after determining that the one or more paging messages are received during the SDT procedure.

Monitoring paging messages and small data transmission

A method for a user equipment (UE) performing a small data transmission (SDT) is provided. The method includes receiving, from a base station (BS), a radio resource control (RRC) release message that includes an SDT configuration when the UE is in an RRC_CONNECTED state; transitioning from the RRC_CONNECTED state to an RRC_INACTIVE state when the UE receives the RRC release message; initiating an SDT procedure based on the SDT configuration when the UE is in the RRC_INACTIVE state; obtaining a default configuration that is preconfigured for the UE and includes a Power Headroom Report (PHR) configuration; and applying the default configuration when the UE initiates the SDT procedure.

A method for a user equipment (UE) of determining a tracking reference signal (TRS) resource set availability is provided. The method includes receiving, from a base station (BS), a TRS configuration that indicates one or more TRS resource sets for the UE to monitor reference signals; determining whether a Layer 1 (L1)-based availability indication for the one or more TRS resource sets is received from the BS; and determining the one or more TRS resource sets are unavailable when the UE determines that the L1-based availability indication has not been received from the BS.
