Abstract: A method of wireless communications by a user equipment (UE) includes decoding information received from a base station via a physical downlink shared channel (PDSCH). The UE determines whether to update channel state feedback based on the decoded information. The channel state feedback is updated based on the determination to generate updated channel state feedback. The updated channel state feedback is transmitted to the base station. The UE is configured to update the channel state feedback without an additional measurement of a channel state information reference signal (CSI-RS).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of reference signals from a base station and may determine a first set of channel state parameters. The UE may determine one or more preprocessed decoder parameters based on a downlink channel decoder of the UE and may perform one or more signal processing operations to determine one or more adjustment values for the first set of channel state parameters. The UE may transmit an indication of a the one or more adjustment values to the base station. In some implementations, the UE may transmit an indication of the one or more preprocessed decoder parameters to the base station and the base station may perform the one or more signal processing operations to determine the one or more adjustment values.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal. The UE may measure the signal to explore one or more inactive ranks or inactive precoders. The UE may transmit, based at least in part on the measuring, a report that includes channel state information for at least one of the one or more inactive ranks or inactive precoders. Numerous other aspects are described.
