Small data transmission method and related equipment

Abstract

A method and user equipment (UE) for small data transmission (SDT) are provided. In the method, an SDT process is initiated. During the SDT process, a synchronization signal / physical broadcast channel block (SSB) is selected. During the SDT process, a transmission is performed based on the selected SSB. A timer is started or restarted in response to performing the transmission. While the timer is running, a downlink control channel (PDCCH) is monitored by assuming that the PDCCH has the same demodulation reference signal (DM-RS) antenna port quasi-co-location characteristics as the selected SSB associated with the transmission.
