Abstract: Aspects relate to sidelink positioning using second stage sidelink control information (SCI-2). A first wireless communication device (e.g., first UE) may transmit SCI-2 including a sidelink positioning establishment message to establish a sidelink positioning session with at least a second wireless communication device (e.g., a second UE). Each of the first UE and second UE may then transmit positioning reference signals (PRSs) and generate and transmit sidelink positioning information based on the PRSs during the sidelink positioning session. The sidelink positioning information may further be transmitted via SCI-2.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a configuration message including at least one information element indicating whether the UE is permitted to initiate sidelink-based positioning sessions, and transmits a positioning reference signal (PRS) request to at least one UE based on the at least one information element indicating that the UE is permitted to initiate sidelink-based positioning sessions.

Abstract: A first user equipment (UE) receives inter-UE coordination information from a second UE. The first UE transmits a sidelink transmission using resources selected based on at least one of the inter-UE coordination information or sensing at the first UE, wherein selection of the resources uses the at least one of the inter-UE coordination information or the sensing based on one or more of a criteria observed at the first UE or an indication from the second UE. The second UE transmits the inter-UE coordination information for sidelink communication. The second UE may transmit information indicating whether to use at least one of the inter-UE coordination information or sensing for sidelink resource selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of resources that are designated for sidelink inter-UE coordination information based at least in part on a sidelink resource pool configuration. The UE may transmit or monitor for a communication that includes inter-UE coordination information in a resource of the set of resources. Numerous other aspects are described.

Abstract: A first user equipment (UE) receives, via first sidelink resources from a second UE, a reservation message that includes an indication of second sidelink resources via which the first UE will subsequently receive a data packet. The first UE may at least one of: determine if the first UE is an intended recipient of the data packet, or compare a reference signal received power (RSRP) value of the reservation message to a threshold value. The first UE may transmit a first reservation forwarding message, via one or more third sidelink resources, including at least the indication of the second sidelink resources to at least a third UE in response to at least one of: determining that the first UE is the intended recipient of the data packet, or determining that the RSRP value is less than the threshold value. The first UE subsequently receives the data packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first sounding reference signal (SRS) transmission that occurred most recently in time, relative to a second SRS transmission, prior to transmission of one or more physical uplink shared channel (PUSCH) communications. The one or more PUSCH communications may correspond to a configured grant. The UE may transmit the one or more PUSCH communications using one or more SRS resources associated with the first SRS transmission. Numerous other aspects are provided.

Abstract: Aspects presented herein relate to methods and devices for wireless communication of an apparatus, e.g., a UE. In one aspect, the apparatus may detect at least one conflict in a set of reserved resources between two or more sidelink (SL) resource reservations, each of the two or more SL resource reservations being associated with each of two or more UEs. The apparatus may also configure at least one of an indication of the at least one conflict or at least one resource reservation forwarding message. The apparatus may also transmit, after detecting the at least one conflict in the set of reserved resources, one or more of at least one resource reservation forwarding message or an indication of the at least one conflict.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adaptively choose a resource selection scheme between a sensed selection scheme and a random selection scheme to determine a sidelink resource. The UE may transmit a sidelink communication utilizing the sidelink resource based at least in part on adaptively choosing the resource selection scheme. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure to techniques for sidelink re-discovery without repeating beamforming in millimeter wave (e.g., Frequency Range 2) bands. For example, a Tx UE may complete a first beam training with a Rx UE. The Tx UE may generate a discovery message that includes at least one of: an indication of a beam training reference signal (BT-RS) sequence index of the first beam training; an indication of a timer for changing the BT-RS sequence; or an indication of a second BT-RS sequence to be used by the Tx UE before an expiration of the timer. The second BT-RS sequence may be indicated as an index to a set of BT-RS sequences including the BT-RS sequence associated with the first beam training. The Tx may transmit the generated discovery message to the Rx UE.

Abstract: User equipments (UEs) may be configured to perform channel occupancy information multi-access reporting. In some aspects, a user equipment may receive a sidelink configuration message identifying the first UE and one or more other UEs as members of a multicast group and a resource to be used for sidelink communications amongst the multicast group, and receive channel occupancy information (COI) from at least one of the one or more UEs within the multicast group, the COI indicating an occupied condition of the resource determined by the at least one of the one or more UEs during a sensing operation performed with respect to the resource. Further, the UE may select a period of time to transmit a sidelink communication based at least in part on the COI.
