Abstract
Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives first signaling triggering the UE to transmit a base channel state information (CSI) report to a network entity. The UE transmits the base CSI report to the network entity in response to the first signaling. The UE takes action to reduce or avoid error propagation when transmitting one or more differential CSI reports that include at least some CSI values reported relative to CSI values in the base CSI report.

A method for wireless communications by a user equipment (UE), comprising:
- receiving first signaling triggering the UE to transmit a base channel state information (CSI) report to a network entity;
- transmitting the base CSI report to the network entity in response to the first signaling;
- taking action to reduce or avoid error propagation when transmitting one or more differential CSI reports that include at least some CSI values reported relative to CSI values in the base CSI report;
- transmitting, to the network entity, a predefined format via uplink control information (UCI) to report a performance loss caused due to the one or more differential CSI reports;
- and
- receiving signaling, from the network entity, indicating a reset of a differential CSI report procedure.
An apparatus for wireless communications by a user equipment (UE), comprising:
- a memory comprising instructions;
- and
- one or more processors configured, individually or in any combination, to execute the instructions to cause the UE to:
- receive first signaling triggering the UE to transmit a base channel state information (CSI) report to a network entity;
- transmit the base CSI report to the network entity in response to the first signaling;
- take action to reduce or avoid error propagation when transmitting one or more differential CSI reports that include at least some CSI values reported relative to CSI values in the base CSI report;
- transmit, to the network entity, a predefined format via uplink control information (UCI) to report a performance loss caused due to the one or more differential CSI reports;
- and
- receive signaling, from the network entity, indicating a reset of a differential CSI report procedure.
