    Abstract: Methods, systems, and devices for wireless communications are described that provide for dynamic resource avoidance and slot aggregation. The described techniques enable a user equipment (UE) in a vehicle-to-everything (V2X) system to select resources for varying transmission of a data packet (e.g., over multiple slots). The UE may determine a set of candidate transmission time intervals (TTIs) for transmission of the data packet based on a resource map, which may involve selecting resources that are unoccupied by other UEs as indicated by the resource map or preempting other UEs based on traffic priority or latency. The UE may transmit a reservation indication indicating resources to be reserved for subsequent transmissions (e.g., retransmission) and a UE receiving the reservation indication may update its resource map.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a first UE determines a set of resources for transmission of one or more sidelink PRSs. The first UE transmits a sidelink control message to reserve the set of resources for the transmission of the one or more sidelink PRSs. In another aspect, the second UE may receive the sidelink control message, and may (e.g., transmit and/or receive/measure) the one or more PRSs in accordance with the sidelink control message. In another aspect, a third UE may receive the sidelink control message, and may determine whether a transmission by the third UE on some or all of the set of resources is permitted based on the sidelink control message.

    Abstract: A positioning method includes: establishing a positioning session between a plurality of positioning devices including a first positioning device and a second positioning device; obtaining line-of-sight/non-line-of-sight status (LOS/NLOS status) for a plurality of positioning device pairs, each being a pair of the plurality of positioning devices; and transmitting a disable message to the first positioning device based on the LOS/NLOS status of at least one of the first positioning device or the second positioning device being non-line-of-sight relative to at least a subset of the plurality of positioning devices, the disable message indicating to disable at least one of transmission of one or more first positioning reference signals from the first positioning device or measurement of one or more second positioning reference signals from the second positioning device by the first positioning device.

    Abstract: A responder user equipment (UE) in separate ranging sessions may determine whether there is a collision between the ranging signals assigned to broadcast in the separate ranging sessions. A collision in the ranging signals is detected when the ranging signals have the same frequencies and broadcast times, e.g., the broadcast time of one ranging signal is within a predetermined amount of time for the other ranging signal. When a collision in the ranging signals is detected, the responder UE sends a message to the initiator UE indicating the possibility of a collision. Available times for broadcasting the ranging signals may be determined, e.g., by the responder UE or the initiator UE. The initiator UE may initiate a new ranging session based on the available times for broadcasting the ranging signal or may proceed with the ranging session with the possibility that the responder UE will not participate.

    Abstract: A user equipment (UE) may sense a first transmission by a first sidelink UE and a second transmission by a second sidelink UE and send a conflict indication to at least one of the first or second sidelink UEs in response to identifying a collision between the first and second transmissions, or identifying a prospective collision based on a prospective use of respective first and second resources identified in the respective first and second transmissions. A collision or prospective collision may be detected by detecting a complete or partial overlap of the first and second transmissions or of the prospective first and second resources identified in the transmissions, or by determining that any portions of the first resource and the second resource prospectively occupy a slot common to the first and second resources, and the first sidelink UE and the second sidelink UE prospectively operate in a half-duplex mode.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive a first set of ranging measurements based at least in part on a first one or more positioning reference signals communicated over a sidelink between a pedestrian user equipment (P-UE) and a vehicle UE (V-UE). The network node may receive a second set of ranging measurements based at least in part on a second one or more positioning reference signals communicated over an access link between the P-UE and one or more base stations. The network node may transmit, to the P-UE, an estimated position of the P-UE. For example, in some aspects, the estimated position of the P-UE may be based at least in part on the first set of ranging measurements and the second set of ranging measurements. Numerous other aspects are provided.
