Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit a first sidelink message via a sidelink channel using a first set of communication parameters, the first sidelink message including data and a reservation for a retransmission resource for retransmission of the first sidelink message. The first UE may receive, from a second UE, a feedback message including a feedback sequence that indicates a negative acknowledgement (NACK) for the first sidelink message and channel state information (CSI) associated with the sidelink channel. The UE may transmit a second sidelink message including the data of the first sidelink message based on the feedback message, where the second sidelink message is transmitted using a second set of communication parameters, or via at least a second resource different from the retransmission resource, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for selecting a resource for a transmission of a self-contained inter-UE coordination message, wherein the configuration indicates an initial time interval, a step size for incrementing the initial time interval, and an available resource ratio associated with a resource selection window, and wherein the initial time interval is incremented by the step size until a quantity of available resources within the resource selection window satisfies the available resource ratio. The UE may select, based at least in part on the configuration, the resource for the transmission of the self-contained inter-UE coordination message from the quantity of available resources within the resource selection window. The UE may transmit the self-contained inter-UE coordination message via the selected resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a sidelink user equipment (UE) may be configured with one or more prioritization rules for sidelink resource reservation forwarding. The UE monitor for one or more sidelink messages that indicate a set of sidelink resource reservations associated with one or more other UEs. In some examples, the UE may receive a sidelink message and one or more other sidelink messages that indicate reservations of other sidelink resources associated with other UEs. The UE may select one or more sets of sidelink resources for indicating in a coordination message in accordance with the one or more prioritization rules for sidelink resource reservation and based on the sidelink messages. The UE may transmit the coordination message including an indication of the one or more sets of sidelink resources based on the selecting.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select, based at least in part on channel sensing, one or more subchannels for transmitting information for coordinating sidelink resources with one or more other UEs. The first UE may transmit, to at least a second UE, sidelink control information (SCI) that indicates the one or more subchannels and one or more data transmission occasions in which the information is to be transmitted. Numerous other aspects are described.
