12. A first user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors operatively coupled to the one or more memories, the one or more memories and the one or more processors configured to:
transmit, to a second UE, a plurality of sidelink transmissions associated with a spatial division multiplexing (SDM) configuration indicating how the plurality of sidelink transmissions are to be spatially multiplexed;
receive feedback indicating a failure to decode at least one sidelink transmission of the plurality of sidelink transmissions, wherein the feedback includes an indication of at least one layer of the SDM configuration associated with the at least one sidelink transmission; and
selectively retransmit the at least one sidelink transmission based at least in part on the feedback.
