Abstract: Aspects are provided which allow a network entity to receive an uplink transmission from a UE in UE DTX or cell DRX based on dynamic activation or deactivation of a DTX configuration or an associated uplink transmission configuration with respect to DTX. In some examples, the UE receives a DTX configuration associated with a UE transmission configuration and indicating an active time duration for a UE transmission associated with the UE transmission configuration. The UE also receives the uplink transmission configuration, such as an SR configuration, and a semi-static or dynamic indication of an active status of the DTX configuration or the uplink transmission configuration with respect to the DTX configuration. Afterwards, the UE transmits the UE transmission during the active time duration indicated in the DTX configuration based on the active status. As a result, less uplink transmission monitoring may result at the base station, providing network energy savings.
