Channel state information report aggregation and uplink control information multiplexing for sidelink communications

A method for wireless communication at a first user equipment (UE), comprising:

• receiving one or more sidelink channel state information reports from one or more second UEs;
• identifying at least one channel state information report pertaining to channel quality between the first UE and a network entity and generated by the first UE to be transmitted to the network entity;
• prioritizing wideband sidelink channel state information reports of the one or more sidelink channel state information reports over wideband channel state information reports or subband channel state information reports of the at least one channel state information report;
• determining, based at least in part on the prioritizing, at least a subset of the at least one channel state information report to transmit in a same channel with the one or more sidelink channel state information reports;
• and
• transmitting, in the same channel, the one or more sidelink channel state information reports received from the one or more second UEs and at least a subset of the at least one channel state information report generated by the first UE.

An apparatus for wireless communication at a first user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a network entity, an indication of a priority associated with each of a plurality of second UEs in sidelink communications with the first UE;
• receive a plurality of sidelink channel state information reports from the plurality of second UEs;
• prioritize each sidelink channel state information report of the plurality of sidelink channel state information reports based at least in part on the priority of a corresponding second UE from which the sidelink channel state information report is received;
• and
• transmit at least a subset of the plurality of sidelink channel state information reports to the network entity based at least in part on the prioritizing.
