1. A method for wireless communication by a transmitter user equipment (TX UE), comprising:
determining, according to a sidelink resource allocation mode, a set of resources, in a resource pool of one or more resource pools associated with the sidelink resource allocation mode, to use for transmitting information to a group of receiver UEs (RX UEs);
transmitting to the group of RX UEs an indication that the TX UE will transmit the information to the group of RX UEs using rate splitting multiple access (RSMA); and
transmitting the information to the group of RX UEs in the set of resources using RSMA, wherein transmitting the information to the group using RSMA comprises:
combining control information for different RX UEs in the group of RX UEs into a common message;
transmitting, in the set of resources, the common message including the combined control information to the group of RX UEs using a first precoder; and
transmitting, in the set of resources, individual private data messages to each RX UE in the group of RX UEs using separate respective precoders different from the first precoder.
