Abstract:
Systems and methods for wireless communication include a user equipment (UE) and a base station, wherein the UE transmits additional channel state information (A-CSI), along with ACK/NACK (or “A/N”) reporting to the base station in a soft A/N payload. The A/N reporting is responsive to downlink control information (DCI) grants in a downlink transmission from the base station. The A-CSI reporting is responsive one or more DCIs which include a CSI trigger. Even if one or more DCIs with CSI triggers are missed in the downlink transmission, the UE is designed to detect whether there may be any missing DCIs with CSI triggers and provide A-CSI reporting in the soft A/N payload based on this detection.
