Abstract: A user equipment (UE) monitors at least one resource subset in a set of resource subsets configured for random selection of a SL transmission resource. The UE selects, based on the monitoring of the at least one resource subset, a resource subset in the set of resource subsets configured for the random selection of the sidelink transmission resource. The UE transmits a sidelink message in a randomly selected transmission resource within the selected resource subset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via sidelink communication, an inter-UE coordination request message requesting coordination information associated with selecting a first resource for transmitting data. The UE may transmit, based at least in part on receiving a negative acknowledgement associated with the inter-UE coordination request message or based at least in part on not receiving feedback associated with the inter-UE coordination request message within a time period, the data via a second resource that is selected based at least in part on sensing information obtained by the UE. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit data associated with a first radio access technology (RAT) on a set of consecutive slots, associated with the first RAT, that map to a time period associated with a second RAT. The UE may determine a set of transmit powers associated with the set of consecutive slots. The UE may transmit the data associated with the first RAT using the set of transmit powers and in accordance with a first numerology. The first numerology may be associated with the first RAT and may be different than a second numerology that is associated with the second RAT. Numerous other aspects are described.

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 communications are described. A user equipment (UE) may receive an indication of a first set of resources that are available for communications associated with a first radio access technology (RAT) and communications associated with a second RAT. The UE may initialize, for at least transmitting one or more sidelink messages using the first RAT, a second set of resources. The second set of resources may include a subset of the first set of resources. The second set of resources may be based on usage information for the second RAT. The UE may select, for transmitting the one or more sidelink messages using the first RAT, one or more resources from the second set of resources and transmit the one or more sidelink messages using the first RAT and the one or more resources from the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive signaling indicating one or more resource reservation rules associated with transmitting a sidelink message that includes reservation information associated with one or more sidelink resources. The first UE may determine, based on the one or more resource reservation rules, to include the sidelink message in a physical layer control signal, or a medium access control layer control signal, or both. The first UE may then transmit, to a second UE, the sidelink message in the physical layer control signal, or the medium access control layer control signal, or both based on the determining.

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: To provide more power efficient SPS transmission for sidelink UEs, methods, apparatuses, and computer-readable medium are provided. An example method may include selecting a first sidelink transmission resource for SPS based on a sidelink sensing procedure for UE-to-UE communication, the first sidelink transmission resource being associated with one or more subchannels within one or more slots. The example method may further include initiating a timer based on a timer range, the timer range being based on one or more of a battery level or a mobility associated with the UE. The example method may further include reselecting a second sidelink transmission resource or maintain the first sidelink transmission resource for the UE-to-UE communication upon an expiration of the timer.
