Abstract:
Methods, systems, and devices for wireless communications are described. A first device, which may be a user equipment (UE), may transmit a sidelink control information SCI) message (e.g., an SCI-1 message) on a physical sidelink control channel (PSCCH) to a group of devices. The SCI may message may reserve a set of sidelink resources for a sidelink communication between the first device and a second device of the group of devices. The first device may receive an acknowledgment (ACK) message on a physical sidelink feedback channel (PSFCH) from the second device. Based on receiving the ACK message, the first device may release the set of sidelink resources and may transmit a release message (e.g., a physical sidelink release channel (PSRCH) message) on a PSRCH that includes an indication of the released set of sidelink resources.
