1. An apparatus for wireless communication at a first user equipment (UE), comprising:
a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the apparatus to:
transmit, during a first transmission time interval, a first sidelink control information message associated with a first sidelink transmission from the first UE, wherein the first sidelink control information message comprises a first indication of a set of resources reserved for retransmissions of the first sidelink transmission at one or more retransmission occasions, wherein the first sidelink control information message further comprises a first identifier that associates the first sidelink control information message with the first UE, a second UE to which the first sidelink transmission was directed, or both;
identify, during a second transmission time interval that is after the first transmission time interval, that a second sidelink control information message provides a release of at least a first subset of the set of resources reserved by the first sidelink control information message based at least in part on the second sidelink control information message comprising a second identifier that associates the second sidelink control information message with a same UE identified by the first identifier; and
transmit the retransmissions of the first sidelink transmission on only a second subset of the set of resources in accordance with the release of the first subset of the set of resources.
