Original Abstract Submitted
A wireless device receives one or more radio resource control (RRC) messages indicating: two control resource set (coreset) group indexes; one or more sounding reference signal (SRS) resource sets; and a respective parameter, for each SRS resource set, for determining a transmission configuration indication (TCI) state among TCI states associated with the two coreset group indexes. The wireless device receives one or more control commands indicating: a first TCI state for a first coreset group index; and a second TCI state for a second coreset group index. The wireless device determines, based on a parameter associated with an SRS resource set, a TCI state among the first TCI state and the second TCI state. The wireless device transmits, via an SRS resource in the SRS resource set, an SRS using a spatial transmission filter determined based on a reference signal of the TCI state.
