Abstract: A measurement period in which a User Equipment (UE) can be configured to take Positioning Reference Signal (PRS) measurements may include receiving PRS resources of a plurality of Positioning Frequency Layers (PFLs). To do so, the UE may tune (RF) circuitry of the UE from an active Bandwidth Part (BWP) to a frequency band of the at least one PFL, receive a plurality of PRS resources of a plurality of PFLs from one or more network nodes, and subsequent to receiving the plurality of PRS resources, re-tune the RF circuitry of the UE to the active BWP. The UE can then determine PRS measurements based on the plurality of PRS resources.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, first information identifying positioning reference signal (PRS) resources. The UE may receive, from a base station, second information identifying sounding reference signal (SRS) resources. The UE may select, from PRS resources identified by the first information, PRS resources that satisfy a PRS-SRS proximity requirement with regard to at least one SRS resource identified by the second information. The UE may use the selected PRS resources at least for performing UE Rx-Tx measurements. In another aspect, a network entity may transmit, to a UE, first information identifying PRS resources. The network entity may transmit, to the UE, second information specifying a number of PRS resources to be used by the UE at least for performing UE Rx-Tx measurements.

Abstract: In an aspect, a UE detects a collision between at least one symbol among first and second sets of symbols of respective SRS-M and SRS-P configurations. The UE selects one of the SRS-M configuration and the SRS-P configuration for transmission on the at least one detected collision symbol, and transmits an SRS transmission in accordance with the selected SRS configuration on the at least one detected collision symbol. In another aspect, a BS transmits configuration of a SRS-M-P, and receives an SRS-M-P transmission from a UE in accordance with the SRS-M-P configuration on at least one symbol.

Abstract: A method of requesting a reference signal includes sending, from a user equipment, a first on-demand reference signal (RS) request for an RS in response to a first positioning request; obtaining, at the user equipment, a first timer value indicative of a first threshold amount of time; sending, from the user equipment, a second on-demand RS request in response to either: the first threshold amount of time passing after sending the first on-demand RS request without at least one of receiving the RS at the user equipment or decoding an RS configuration message at the user equipment or receiving, at the user equipment, a second positioning request, having a higher priority than the first positioning request, before passage of the first threshold amount of time after sending the first on-demand RS request.

Abstract: Methods, systems, computer-readable media, and apparatuses for UE positioning are described. In some embodiments, a UE is configured to perform positioning measurements according to capabilities of the UE. Over time, the capabilities may change. Based on a change, the UE reports, to a location server, an indication that the capabilities have changed. This indication can include updated capabilities information or an error related to previously reported capabilities information and/or availability of the updated capabilities information. In turn, the location server may indicate, to the UE, updated assistance data and/or a request for updated location information, such that next position measurements performed by the UE may be based on the updated assistance data and/or the request.

Abstract: A UE receives a first configuration for at least one RRM measurement gap. The UE receives one or more PRSs prior to the at least one RRM measurement gap. The UE identifies whether a processing availability of the UE during the at least one RRM measurement gap is sufficient to process the one or more PRSs. The UE processes the one or more PRSs, where in response to the processing availability of the UE during the at least one RRM measurement gap, the one or more PRSs are processed during the at least one RRM measurement gap; and in response to lack of the processing availability of the UE sufficient to process the one or more PRSs during the at least one RRM measurement gap, the one or more PRSs are processed, at least in part, outside of the at least one RRM measurement gap.

Abstract: Techniques are provided for combining positioning reference signal (PRS) measurements coherently or non-coherently. An example method for combining positioning reference signal resources includes receiving a plurality of positioning reference signals associated with a positioning reference signal resource set or a transmission/reception point, coherently combining resource elements for two or more of the plurality of positioning reference signals received within a period of time, and non-coherently combining resource elements for two or more of the plurality of positioning reference signals received outside of the period of time.

Abstract: In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving, at an apparatus (e.g., a user equipment (UE) or component of the UE), a plurality of resource blocks associated with a positioning reference signal (PRS). A comb structure of the PRS is repeated in less than all resource blocks of the plurality of resource blocks. The process includes transmitting a phase measurement report to a first network entity. The phase measurement report includes information associated with a measured phase difference between at least one subcarrier set pair of the plurality of resource blocks. As described herein, a subcarrier set includes at least one subcarrier.
