1. A method of wireless communication performed by a user equipment (UE), the method comprising:
obtaining, by the UE, an uplink control information (UCI) message resource allocation;
receiving, by the UE, at least one sidelink channel state information (CSI) report from one or more sidelink UEs in communication with the UE;
determining, by the UE, the UCI message resource allocation includes insufficient resources to transmit all of the at least one sidelink CSI report;
determining, by the UE, that each sidelink UE of the one or more sidelink UEs has a same priority level;
determining, by the UE, a report priority level of each sidelink CSI report of the at least one sidelink CSI report;
identifying one or more sidelink CSI reports of the at least one sidelink CSI report by:
sequentially allocating the one or more sidelink CSI reports to the UCI message resource allocation according to a descending report priority level beginning with a first sidelink CSI report of the one or more sidelink CSI reports having a highest report priority, wherein the sequentially allocating continues until one of:
each resource block (RB) of the UCI message resource allocation for CSI reporting is allocated, or
a code rate of the one or more sidelink CSI reports is less than or equal to a configured code rate configured for the one or more sidelink CSI reports; and
transmitting, by the UE, a UCI message via the UCI message resource allocation, wherein the UCI message includes the one or more sidelink CSI reports of the at least one sidelink CSI report.
