Abstract: A transmitting user equipment (UE) may perform resource hopping for a periodic sidelink resource reservation by scheduling a plurality of periodic sidelink resources with a first periodicity, the plurality of periodic sidelink resources being shifted at a first offset in a frequency domain. The transmitting UE may reduce persistent collisions of periodic or semi-persistent scheduling (SPS) reservation of the sidelink resources with another UE. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) indicating the first offset and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI. The receiving UE may receive, from the transmitting UE, the SCI and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a buffer status report associated with a one-to-many sidelink communication. The UE may receive, from the base station, one or more downlink control information (DCI) messages scheduling one or more sidelink communications, associated with one or more spatial transmission directions, for the one-to-many sidelink communication, wherein the one or more DCI messages allocate resources for each of the one or more spatial transmission directions. The UE may transmit, using the resources and in the one or more spatial transmission directions, the one or more sidelink communications for the one-to-many sidelink communication. 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 receive, from a second UE, a first message that indicates a sidelink bandwidth part (BWP) switch, for the second UE, to a first sidelink BWP, where the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The first UE may transmit, to the second UE, a second message that confirms the sidelink BWP switch for the second UE. The first UE may receive, from the second UE, a third message that activates the sidelink BWP switch, for the second UE, to the first sidelink BWP. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to sidelink communication between user equipments (UEs). A first UE transmits, to a second UE using a first transmit beam, sidelink control information (SCI) identifying a scheduled resource for a second message and a physical sidelink shared channel (PSSCH) message. The first UE receives, from the second UE using a first receive beam associated with the first transmit beam, an indication of a resource collision associated with the first UE, the second UE, and a third UE. The first UE and performing an action in response to the indication, wherein the action includes at least one of dropping the second message, or re-transmitting, to the second UE, the PSSCH message with the scheduled resource for the second message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.
