1. A user equipment (UE), comprising:
a transceiver configured to wirelessly communicate with a base station; and
a processor communicatively coupled to the transceiver and configured to:
receive, using the transceiver and from the base station, a downlink message including a channel state information (CSI) reporting configuration;
perform, based at least in part on the CSI reporting configuration, CSI measurements during a current reference time period;
generate one or more CSI reports, wherein a CSI report of the one or more CSI reports includes at least a first part and a second part, the first part being a Type I standard-resolution report and the second part being a Type II high resolution report, the first part generated based at least in part on the CSI measurements performed during the current reference time period, and the second part including at least a stale CSI report generated based at least in part on CSI measurements performed prior to the current reference time period;
generate an uplink message including the one or more CSI reports; and
transmit, using the transceiver, under a reporting setting determined by the CSI reporting configuration, the uplink message to the base station.
