Abstract: Methods, systems, and devices for wireless communications are described. A vehicle user equipment (VUE) may transmit an iterative wake-up signal (WUS) to a first roadside unit (RSU). The iterative WUS may include location information associated with an expected path of the VUE and may instruct the first RSU to transmit one or more other WUSs to at least a second RSU that supports communication along a portion of the expected path of the VUE. In some cases, the first RSU may transmit an iterative WUS to the second RSU, the second RSU may transmit an iterative WUS to a third RSU, and so on until the final RSU along the expected path is woken up with a normative (e.g., non-iterative) WUS. An RSU may provide safety information to the VUE, and after the VUE leaves a service area associated with an RSU, the RSU may activate a low power mode.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may receive an indication of a session key from an initiator UE in a sidelink communications system, from a network entity (e.g., a base station), or the like. In some cases, the target UE may also receive an indication of a nonce in a message of a PRS procedure. The target UE may select a positioning reference signal (PRS) sequence for the PRS procedure using the session key and optionally the nonce, such as by using a defined function at the target UE with the session key and the nonce as an input. Once the target UE selects the PRS sequence, the target UE may encode the PRS sequence and may transmit the PRS sequence to the initiator UE.

Abstract: Certain aspects of the present disclosure provide techniques for sub-band full-duplex resource management for sidelink. A method that may be performed by a user equipment first (UE) includes transmitting, to a second UE, information indicating one or more resource assignments for one or more transmissions to the second UE and communicating with the second UE in a full-duplex manner based on the one or more resource assignments.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to select a synchronization signal from multiple synchronization signals received at transceiver nodes of the UE based on configured selection rules. The UE may receive control signaling from another UE, a base station, or some other device indicating a rule for selecting between multiple synchronization signals received across transceiver nodes of the UE. The selection rule may indicate signal quality comparison metrics for selecting the synchronization signal, such as reference signal received power (RSRP) metrics, timing metrics, priority metrics, or a combination thereof. The UE may select a synchronization signal for deriving a timing at the UE based on the selection rule. The UE may forward the selected synchronization signal to one or more other UEs by transmitting the selected synchronization signal via each transceiver node at the UE.

Abstract: Methods, systems, and devices for wireless communications are described in which multiuser superposition transmission (MUST) is used to provide multiple concurrent sidelink transmissions using a same set of time and frequency resources. A transmitting user equipment (UE) may provide an indication of concurrent MUST transmissions in sidelink control information (SCI), and a receiving UE may decode one or both of a MUST base layer communication and a MUST enhancement layer communication. The base layer communication may include broadcast or groupcast transmissions to multiple UEs, and the enhancement layer communication may include a unicast transmission between the transmitting UE and a single receiving UE. The indication of concurrent transmissions may be provided in a first stage SCI, and parameters for decoding the base layer and enhancement layer transmissions may be provided in one or multiple second stage SCI transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A server may request sensed location information from a first device to verify location information reported by the first device or one or more additional devices. For example, a first user equipment (UE) may receive a message requesting sensed location information for verification of the location information associated with and reported by the first UE. Based on a sensing procedure performed by the first UE, the first UE may transmit a report indicating the sensed location information and a sensing time. In another example, a first device may receive a message requesting sensed location information for verification of the location information associated with and reported by one or more additional devices. Based on a sensing procedure performed by the first UE, the first UE may transmit a report indicating the sensed location information and the sensing time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via reflection by one or more passive devices, a first reference signal (RS) that is based at least in part on a shared first key that corresponds to a configuration of the one or more passive devices. The first UE may receive, from the second UE via reflection, a second RS that is based at least in part on the first key. The first UE may generate a second key based at least in part on a measurement of the second RS. The first UE may transmit a positioning reference signal that is based at least in part on the second key and that is associated with a measurement of a range between the first UE and the second UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for using situational information to aid in beam-based communications between a first user equipment (UE) and a network entity. The first UE may collect data at one or more sensors and may generate the situational information using the collected data. The first UE may then use the situational information in a beam selection procedure to identify suitable candidate beams for communicating with the network entity. The first UE may also transmit the situational information to the network entity in a beam management report, and the network entity may use the situational information to identify suitable candidate beams for communicating with the first UE. In some cases, the network entity may also use the situational information to identify suitable candidate beams for communicating with a second UE associated with the first UE.
