Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a single layer reference signal. The UE may perform single layer measurements associated with the single layer reference signal for a plurality of UE beam pairs. The UE may determine, based at least in part on the single layer measurements for the plurality of UE beam pairs, multiple layer measurements associated with one or more UE beam pairs of the plurality of UE beam pairs. The UE may select, from the one or more UE beam pairs, a UE beam pair based at least in part on the multiple layer measurements associated with the one or more UE beam pairs. Numerous other aspects are described.

Abstract: Techniques are provided for passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first station at a first time, receiving a second positioning reference signal from a second station at a second time, receiving a turnaround time value associated with the first positioning reference signal and the second positioning reference signal, and a distance value based on a location of the first station and a location of the second station, and determining a time difference of arrival based at least in part on the turnaround time value, the distance value, the first time, and the second time.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration indicating a pattern of PRS resources transmitted by at least one network node, and transmits a proposed measurement gap pattern to a serving network node, the proposed measurement gap pattern enabling the UE to measure at least a subset of PRS resources transmitted by each of the at least one network node, the proposed measurement gap pattern determined based on the pattern of PRS resources.

Abstract: Techniques for position estimation using uplink (UL) and downlink (DL) signals via a fully or partially reciprocal wireless channel between a User Equipment (UE) and terrestrial transceiver can be enhanced by leveraging information obtained from UL or DL signals having the stronger Signal-to-Noise Ratio (SNR). This information can include the number of paths and/or complex sinusoids, and can be shared with the base station or location server to parameterize the model of the wireless channel. In some embodiments, the UE can further determine a quality metric for the model and send it to the location server or terrestrial transceiver.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may perform a clear channel assessment on a medium to determine if the medium is available for communications with a second wireless device. Based on a successful clear channel assessment, the first wireless device may transmit a medium reservation message to the second wireless device. The second wireless device may then transmit a reservation response message to the first wireless device, where the reservation response message includes synchronization information for the first device to synchronize with the second wireless device. The synchronization information may include a duration of a channel occupancy time, a duration of a synchronous contention window, and/or a duration in which the first wireless device is to maintain synchronization with the second wireless device. Accordingly, the first wireless device and the second wireless device may communicate based on the synchronization information via the medium.

Abstract: A signal measuring method includes: receiving, at a user equipment, first positioning assistance data having a first area of applicability and a first positioning assistance data profile; storing the first positioning assistance data at the user equipment; determining, at the user equipment, that second positioning assistance data correspond to the first positioning assistance data based on the first area of applicability including a second area of applicability, of the second positioning assistance data, and based on a second positioning assistance data profile of the second positioning assistance data corresponding to the first positioning assistance data profile; and measuring, at the user equipment, a positioning signal corresponding to the second area of applicability using the first positioning assistance data in response to determining that the second positioning assistance data correspond to the first positioning assistance data.

Abstract: Disclosed are systems, methods, and non-transitory media for providing signaling consideration for wireless positioning with disjoint bandwidth segments. For instance, one or more indications of a preferred bandwidth configuration can be transmitted by a user equipment. Based on the one or more indications, the user equipment can receive a positioning configuration that indicates disjoint bandwidth segments containing a positioning reference signal based on the preferred bandwidth configuration. In response, the user equipment can then determine one or more positioning measurements based on the positioning reference signal in the disjoint bandwidth segments.
