Abstract: Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.

Abstract: A UE determines a group identifier based at least in part on a timing advance (TA) associated with the UE, the group identifier associated with at least the UE and a second UE and receives a sidelink resource allocation associated with the group identifier. The UE transmits sidelink communication using the sidelink resource allocation. A network node associates a UE with a group identifier based on a timing advance (TA) associated with the UE and transmits a sidelink resource allocation associated with the group identifier, the group identifier associated with at least the UE and a second UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a first signal for positioning (RS-P) (e.g., SRS, etc.) on a first link from the UE to a wireless network node (e.g., BS, UE, etc.). The UE receives, from the wireless network node, location assistance data that comprises information that indicates a line of sight (LOS) condition associated with the first link. The UE measures a second RS-P on a second link from the wireless network node to the UE that is reciprocal to the first link. The UE performs one or more positioning measurements, determines a location estimate of the UE, or both, based in part on the reception of the second RS-P on the second link and the indicated LOS condition, the indicated LOS condition associated with the second link based on link reciprocity between the first and second links.

Abstract: In an aspect, a network component (e.g., BS, LMF, etc.) determines a capability of the UE perform receive frequency hopping to measure a downlink positioning reference signal (DL-PRS) across a plurality of frequency hops, the DL-PRS transmitted over a plurality of orthogonal frequency division multiplex (OFDM) symbols on a same transmission bandwidth (e.g., without frequency hopping), and each of the plurality of frequency hops associated with a sub-band of the transmission bandwidth of the DL-PRS, and configures one or more parameters associated with positioning of the UE based at least in part on the capability. In some designs, the UE may send an indication of the capability to the network component to facilitate the determination, while in other designs the network component may determine the capability via another mechanism.

Abstract: Methods of reducing the interferences of radar signals with uplink or downlink data communication signals in a wireless system for both data communication and radar sensing may include configuring the transmitters of the radar signals and the data communication signals such that the data communication signals and the radar signals are transmitted using different radio frequency resources, and/or configuring the receivers of the data communication signals to receive the data communication signals using a receive beam that does not collide with radar beams. The methods may also include using a reference signal for both downlink data communication and radar sensing and/or determining a Quasi-Colocation (QCL) configuration for downlink data reception based on information regarding a radar beam.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may identify at least one communication resource from a plurality of communication resources for transmitting a positioning report, wherein the plurality of communication resources for transmitting the positioning report have different priorities. The UE may transmit the positioning report via the at least one communication resource, wherein the at least one communication resource comprises at least one of a medium access control (MAC) control element (MAC-CE) logical channel ID or a signaling radio bearer (SRB).

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from one or more transmission-reception points (TRPs), one or more on-demand downlink positioning reference signals (DL-PRS), the one or more on-demand DL-PRS having one or more downlink transmission parameters, and transmits, to the one or more TRPs, one or more uplink positioning reference signals (UL-PRS), the one or more UL-PRS having one or more uplink transmission parameters, wherein values of the one or more uplink transmission parameters are the same as or within a threshold of values of the one or more downlink transmission parameters.

Abstract: Sounding reference signals (SRS) transmitted by a UE, e.g., for positioning or channel estimation, may be configured for one or both of frequency tone level cyclic shift and symbol level code, which, for example, enables multiplexing a greater number of UEs. The frequency tone level cyclic shift is produced by jointly processing a number of symbols with an extended cyclic shift structure. The SRS may be configured using a symbol group level that indicates the number of symbols associated with a cyclic shift structure, and an outer code that indicates a multiplier applied to the SRS at the symbol level, which increases the multiplexing opportunities. The symbol level code may further indicate an extended cyclic shift indicating a linear increase in phase rotation across tones in symbols associated with the symbol group level.

Abstract: In at least one embodiment, a user equipment (e.g., a mobile device) may receive a location request message from a server (e.g., a Location Management Function), wherein the location request message identifies a plurality of Quality of Service parameters for the LTE Positioning Protocol (LPP) positioning session. In at least one embodiment, the user equipment may receive a selection of one or more Quality of Service parameters for the LPP positioning session. In at least one embodiment, the user equipment may configure the user equipment according to the one or more selected Quality of Service parameters. In at least one embodiment, the user equipment may generate a location response message according to the selected QoS parameters. The user equipment may send the location response message to the server. A UE can select the QoS parameters during communication with a server and/or with a second UE via sidelink communications.
