1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a base station, an uplink precoding matrix indicator for uplink transmissions of the UE, wherein one or more of the uplink transmissions are to be transmitted concurrently with one or more downlink transmissions that are to be received at the UE on frequency resources that at least partially overlap with frequency resources for the uplink transmissions;
determining, based at least in part on the uplink precoding matrix indicator and measurements of a downlink reference signal received from the base station, a channel state information report that is based at least in part on a self-interference estimate of concurrent uplink and downlink transmissions according to the uplink precoding matrix indicator and on the measurements of the downlink reference signal; and
transmitting the channel state information report to the base station.
