Signaling design for joint uplink data and channel state information feedback

Abstract:

A user equipment (UE) may be configured with a first set of indexed timing offsets for determining offsets between uplink grants and uplink data transmissions and a second set of indexed timing offsets for determining offsets between an aperiodic channel state information (CSI) trigger and transmission of an aperiodic CSI report. A UE may receive both an uplink grant for an uplink data transmission and an aperiodic CSI report trigger. The UE may determine a timing offset for transmission of both the uplink data transmission and the aperiodic CSI report. The timing offset may be based at least in part on the first set of indexed timing offsets, the second set of indexed timing offsets, or a third set of indexed timing offsets for joint transmission of uplink data and aperiodic CSI. The UE may transmit the uplink data transmission and the aperiodic CSI report according to the timing offset.
