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: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first demodulation reference signal (DMRS) pattern for a first slot allocated for transmission over a sidelink between the transmitter UE and a receiver UE, wherein the first DMRS pattern is determined based at least on the first slot having a first slot format of two or more slot formats, and transmits, to the receiver UE, DMRS in the first slot according to the first DMRS pattern. In an aspect, the receiver UE determines the first DMRS pattern for the first slot based at least on the first slot having the first slot format, and receives, from the transmitter UE, DMRS in the first slot according to the first DMRS pattern.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first quantity of physical sidelink feedback channel (PSFCH) transmissions to be transmitted in a slot fails to satisfy a condition that is based at least in part on a maximum quantity of PSFCH transmissions the UE can concurrently detect. The UE may identify, among the PSFCH transmissions to be transmitted in the slot, a subset of the PSFCH transmissions to be detected. For example, the subset of the PSFCH transmissions to be detected may include a second quantity of the PSFCH transmissions that satisfies the condition. Accordingly, the UE may monitor, during the slot, a PSFCH for the subset of the PSFCH transmissions. Numerous other aspects are provided.
