A user equipment (UE) and a method for small data transmission (SDT) are provided. The method includes receiving a Radio Resource Control (RRC) release message from a Base Station (BS), the RRC release message indicating an SDT configuration including a Configured Grant (CG) configuration and a timer; initiating a transmission on an Uplink (UL) resource while the UE is in an RRC_INACTIVE state, the UL resource being either configured by the CG configuration or scheduled by a UL grant from the BS; starting or restarting the timer after initiating the transmission; and monitoring a Physical Downlink Control Channel (PDCCH) addressed to a specific Radio Network Temporary Identifier (RNTI) on a specific search space while the timer is running.

Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may be configured to receive a downlink control message (e.g., an uplink grant) that schedules resources for transmitting repetitions of an uplink channel transmission, where each of the repetitions of the uplink channel transmission may correspond to a single transport block. The UE may determine a plurality of sounding reference signal (SRS) resources based on the downlink control message, and transmit different instances of the uplink channel transmission repetitions according to different SRS resources. The described examples for uplink repetitions may support various techniques for uplink coverage enhancement and diversity gains.
