Abstract: Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE obtains measurement data associated with at least one PRS. The UE transmits, to a BS in a first L1 or L2 PSI report opportunity, a first PSI report indicative of a first set of measurement values associated with the at least one PRS based on the measurement data. The UE further transmits, to the BS in a second L1 or L2 PSI report opportunity that is subsequent to the first L1 or L2 PSI report opportunity, a second PSI report that is indicative of a second set of measurement values associated with the at least one PRS based on the measurement data, the second set of measurement values being refined from the first set of measurement values.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an assisting user equipment (UE) receives a request to perform a positioning procedure from a target UE over a sidelink between the assisting UE and the target UE, wherein the assisting UE and the target UE are both out of network coverage, determines, based at least on the request, a set of time and/or frequency resources on which to transmit one or more positioning reference signals for the positioning procedure, and transmits the one or more positioning reference signals to the target UE via the set of time and/or frequency resources.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: A method, at a transmission/reception point (TRP), of producing a positioning reference signal muting pattern includes: obtaining, at the TRP, one or more positioning reference signal criteria, the one or more positioning reference signal criteria regarding at least one of positioning reference signal transmission or positioning reference signal reception; and producing, at the TRP, the positioning reference signal muting pattern such that the positioning reference signal muting pattern meets the one or more positioning reference signal criteria

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engaged in a positioning session with a plurality of transmission-reception points (TRPs) receives a downlink positioning reference signal (DL-PRS) configuration specifying one or more DL-PRS resource sets of a DL-PRS instance, wherein all DL-PRS resources of the one or more DL-PRS resource sets of the DL-PRS instance are scheduled within a time window, and receives an uplink PRS (UL-PRS) configuration specifying one or more UL-PRS resource sets, wherein all of the one or more UL-PRS resources are scheduled within the time window. The UE may perform, during the time window, measurements of DL-PRS transmissions on one or more DL-PRS resources of the one or more DL-PRS resource sets, and transmit, during the time window, at least one UL-PRS on the one or more UL-PRS resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits capability information indicating a maximum number of downlink resources for both positioning reference signal (PRS) resources and downlink resources for one or more second downlink channels or signals that the UE is capable of processing per unit of time, receives, from a serving transmission-reception point (TRP), a configuration of one or more downlink resources for the one or more second downlink channels or signals, wherein a number of the one or more downlink resources is less than the maximum number, and receives, from a location server, a configuration of one or more PRS resources for the serving TRP, one or more neighboring TRPs, or both, wherein a number of the one or more PRS resources is less than the maximum number.

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.
