Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a weighted number of UEs that is based at least in part on respective resource utilizations by the UEs, a resource utilization limit for the UE. The UE may selectively transmit a communication based at least in part on the resource utilization limit for the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for requesting inter-UE coordination messages for sidelink communications. In some cases, a method for wireless communications by a first user equipment (UE), include sending a first sidelink transmission to at least one second UE to trigger the second UE to transmit a report regarding sidelink resource availability and monitoring for a second sidelink transmission from the second UE after sending the first sidelink transmission.

Abstract: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may identify a configuration for discontinuous reception (DRX) for direct link communications with a second UE. The first UE may determine a channel busy ratio (CBR) based on a plurality of CBR measurement occasions within a time window prior to a direct link transmission based on the configuration for DRX. The first UE may determine whether to perform a congestion control on the direct link transmission based on the CBR. The first UE may perform a direct link transmission subject to a channel occupancy ratio limit.

Abstract: Aspects of the disclosure relate to transmitting, from a first user equipment (UE) to a second UE, a resource report indicative of an availability of a set of resources among a sidelink resource pool based on a measurement of interference in the set of resources. The resource report includes resource availability information indicating that a reserved set of resources reserved for a third UE is available based on an interference parameter associated at least in part with the second UE or the third UE. Other aspects, and features are also claimed and described.

Abstract: Examples of the disclosure relate to generating a packet for transmission over a sidelink resource pool and transmitting the packet to a second UE on a set of sidelink resources of the sidelink resource pool. The set may be selected based on a resource selection procedure of a plurality of resource selection procedures. The resource selection procedure may be selected based at least in part on one or more utilization parameters corresponding to one or more resources of the sidelink resource pool. Other examples, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) user equipment (UE) may receive, from a plurality of receiving (Rx) UEs, indications of channel busy ratios (CBRs) associated with the plurality of Rx UEs, respectively. The Tx UE may combine the CBRs to obtain a combined CBR associated with the Tx UE. The Tx UE may adjust a resource utilization based at least in part on the combined CBR associated with the Tx UE. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select one or more candidate sidelink resources, from within a resource selection window after sensing a sidelink channel, that are available for a second UE to use for transmission to the first UE. The UE may schedule, from among the candidate sidelink resources based at least in part on signal-to-interference ratios for the candidate sidelink resources, one or more scheduled sidelink resources that are preferred for transmission to the first UE. The UE may transmit, to the second UE, an indication of the candidate sidelink resources and the one or more scheduled sidelink resources. Numerous other aspects are described.
