Procedure for combining HD/FD CSI in one report on PUSCH/PUCCH transmissions

A method of wireless communication at a UE, comprising:

• receiving uplink control information (UCI) configuration information from a base station, the UCI configuration information including one or more parameters for multiplexing half-duplex (HD) channel state information (CSI) and full-duplex (FD) CSI as a combined CSI report;
• receiving, from the base station, a first reference signal associated with a HD mode;
• receiving, from the base station, a second reference signal associated with a FD mode;
• determining base information based on measuring the first reference signal;
• determining differential information based on the base information and measuring the second reference signal;
• and
• transmitting, to the base station, the combined CSI report based on the one or more parameters, the first reference signal, and the second reference signal,
• wherein the differential information is included in an excludable part of the combined CSI report.

A base station for wireless communication, comprising:

• a memory storing computer-executable instructions;
• and
• at least one processor coupled with the memory and configured to execute the computer-executable instructions to:
• generate uplink control information (UCI) configuration information for a user equipment, the UCI configuration information including one or more parameters for configuring a UE to multiplex half-duplex (HD) channel state information (CSI) and full-duplex (FD) CSI as a combined CSI report;
• transmit the UCI configuration information to the UE;
• transmit, to the UE, a first reference signal associated with a HD mode and a second reference signal associated with a FD mode;
• and
• receive, from the UE, the combined CSI report based on the one or more parameters, the first reference signal, and the second reference signal,
• wherein the one or more parameters configure the UE to generate the combined CSI report to include base information based on UE measurement of the first reference signal, differential information based on the base information and UE measurement of the second reference signal, and wherein the differential information is included in an excludable part of the combined CSI report.
