SUB-BAND CHANNEL STATE INFORMATION REPORTING FOR ULTRA-RELIABLE LOW LATENCY COMMUNICATIONS

Abstract:

Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.
