TECHNIQUES FOR SIDELINK RESOURCE CANCELLATION USING TIME RESOURCE INDICATOR VALUE

Abstract:

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a first sidelink control information (SCI) message associated with a sidelink transmission from the first UE, the first SCI message including a first indication of a set of resources reserved for retransmissions of the sidelink transmission at one or more retransmission occasions. The first UE may identify a second SCI message associated with the first SCI message, the second SCI message including one or more time domain resource allocation (TDRA) field values indicative of at least a first subset of the set of resources and a release of the at least first subset of the set of resources reserved for the retransmissions of the sidelink transmission, the release pertaining to at least one retransmission occasion of the one or more retransmission occasions. The first UE may then transmit fewer retransmissions of the sidelink transmission in accordance with the release.
