CHANNEL STATE INFORMATION (CSI) REPORTING
Various aspects of the present disclosure relate to channel state information (CSI) reporting. An apparatus, such as a user equipment (UE), receives a configuration message for CSI reporting, the configuration message indicating one or more configuration parameter sets for different sets of slots in a bandwidth part (BWP); and transmits, based at least in part on the configuration message and the one or more configuration parameter sets, at least one CSI report indicating a first CSI report quantity including a first value for a first set of slots associated with sub-band full duplex (SBFD) symbols and a second value for a second set of slots associated with non-SBFD symbols corresponding to downlink (DL) transmission.
1 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a configuration message for channel state information (CSI) reporting, the configuration message indicating one or more configuration parameter sets for different sets of slots in a bandwidth part (BWP); and
transmit, based at least in part on the configuration message and the one or more configuration parameter sets, at least one CSI report indicating a first CSI report quantity comprising a first value for a first set of slots associated with sub-band full duplex (SBFD) symbols and a second value for a second set of slots associated with non-SBFD symbols corresponding to downlink (DL) transmission.

3 . The UE of claim 2 , wherein the at least one CSI report indicates a second CSI report quantity comprising a first value for the at least one sub-band group and a second value for the at least one other sub-band group.
4 . The UE of claim 3 , wherein the second CSI report quantity corresponds to a channel quality indicator (CQI), the at least one CSI report indicating a first CQI value associated with the at least one sub-band group and a second CQI value associated with the at least one other sub-band group.
5 . The UE of claim 3 , wherein the second CSI report quantity corresponds to a precoding matrix indicator (PMI), the at least one CSI report indicating a first PMI value associated with the at least one sub-band group and a second PMI value associated with the at least one other sub-band group.
6 . The UE of claim 5 , wherein the SBFD symbols are associated with three sub-band groups corresponding to two non-contiguous DL sub-bands and one UL sub-band, the at least one CSI report indicating a distinct PMI value for each of the three sub-band groups.
7 . The UE of claim 2 , wherein the configuration message includes two CSI reporting sub-configurations corresponding to two of: the SBFD symbols, the non-SBFD symbols, the at least one sub-band group, or the at least one other sub-band group.
8 . The UE of claim 7 , wherein each of the CSI reporting sub-configurations is associated with at least one of a CSI sub-report or a CSI report.
9 . The UE of claim 1 , wherein the first CSI report quantity corresponds to a channel quality indicator (CQI), the at least one CSI report indicating a first CQI value for the first set of slots and a second CQI value for the second set of slots.
10 . The UE of claim 1 , wherein the SBFD symbols are associated with two sub-band groups corresponding to one downlink (DL) sub-band and one uplink (UL) sub-band, the at least one CSI report indicating a distinct precoding matrix indicator (PMI) value for each of the two sub-band groups.
11 . The UE of claim 10 , wherein the at least one CSI report indicates a common channel quality indicator (CQI) value for the SBFD symbols and the non-SBFD symbols.
12 . The UE of claim 1 , wherein the at least one CSI report indicates a common precoding matrix indicator (PMI) value for the SBFD symbols and the non-SBFD symbols.
13 . The UE of claim 1 , wherein the at least one CSI report indicates a common rank indicator (RI) value for the SBFD symbols and the non-SBFD symbols.
14 . The UE of claim 1 , wherein the at least one CSI report includes a first part and a second part, each part associated with one or more CSI parameters, and the second part including one or more groups.
15 . The UE of claim 14 , wherein a first group of the one or more groups includes a first set of precoding matrix indicator (PMI) parameters associated with the SBFD symbols, and a second group of the one or more groups includes a second set of PMI parameters associated with the non-SBFD symbols.
16 . The UE of claim 1 , wherein the configuration message includes an identification of a configuration message associated with an SBFD symbols-related configuration.
17 . A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
receive a configuration message for channel state information (CSI) reporting, the configuration message indicating one or more configuration parameter sets for different sets of slots in a bandwidth part (BWP); and
transmit, based at least in part on the configuration message and the one or more configuration parameter sets, at least one CSI report indicating a first CSI report quantity comprising a first value for a first set of slots associated with sub-band full duplex (SBFD) symbols and a second value for a second set of slots associated with non-SBFD symbols corresponding to downlink (DL) transmission.
18 . The processor of claim 17 , wherein the first set of slots includes at least one sub-band group associated with uplink (UL) transmission and at least one other sub-band group associated with DL transmission.

receiving a configuration message for channel state information (CSI) reporting, the configuration message indicating one or more configuration parameter sets for different sets of slots in a bandwidth part (BWP); and
transmitting, based at least in part on the configuration message and the one or more configuration parameter sets, at least one CSI report indicating a first CSI report quantity comprising a first value for a first set of slots associated with sub-band full duplex (SBFD) symbols and a second value for a second set of slots associated with non-SBFD symbols corresponding to downlink (DL) transmission.
20 . A network equipment (NE) for wireless communication, comprising:
