Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station via an uplink control channel, a negative acknowledgement (NACK) when a downlink shared channel transmission is not successfully received at the UE. The UE may receive, from the base station and based at least in part on the NACK, one or more channel state information reference signals (CSI-RSs) at one or more semi-persistent CSI measurement occasions. The UE may transmit, to the base station, one or more CSI reports at one or more semi-persistent CSI reporting occasions corresponding to the one or more semi-persistent CSI measurement occasions, wherein the one or more CSI reports include one or more channel measurements based at least in part on the one or more CSI-RSs. Numerous other aspects are provided.
