Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location is represented as a hierarchy of two or more levels of description, wherein a highest level of description is relative to a fixed reference point, receives, from each of at least a subset of the plurality of transmission points, at least one positioning reference signal, and estimates the location of the UE based on characteristics of reception of the at least one positioning reference signal from each of the subset of the plurality of transmission points and the two or more levels of description and the fixed reference point for each of the subset of the plurality of transmission points.

Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

Abstract: A method of coordinating positioning signaling includes: sending, from a user equipment (UE), a request wirelessly for positioning service; receiving, at the UE, an indication of UE positioning signal times for sending UE positioning signals; and sending, from the UE, the UE positioning signals at the UE positioning signal times.

Abstract: Disclosed are techniques for using sounding reference signal (SRS) for positioning. In an aspect, a UE receives an SRS configuration, the SRS configuration defining one or more SRS resource sets, each SRS resource set comprising one or more SRS resources, and each SRS resource comprising one or more SRS ports, wherein at least one SRS port of at least one SRS resource of at least one SRS resource set defined in the SRS configuration is usable by the UE at least for positioning. The UE transmits a positioning SRS utilizing one or more positioning SRS ports, wherein the positioning SRS is transmitted in a positioning SRS pattern such that across N consecutive symbols, where N is greater than or equal to two, SRS resource elements (REs) to which the one or more positioning SRS ports are mapped are staggered in frequency and use each of the N consecutive symbols.

IPC: H04W64/00

Abstract: A user equipment (UE) configured for position determination receives positioning assistance data from a location server that is positioning method specific and provides information related to the prioritization of one or more of frequency layers, transmission points (TRPs), Positioning Reference Signal (PRS) resource sets, and PRS resources or a combination thereof. The positioning assistance data may be generated by the location server in response to the UE measurement capabilities. The UE determines a prioritization for PRS measurements based at least on one or more orderings of the information for the frequency layers, the TRPs, the PRS resource sets, or the PRS resources in the positioning assistance data, or a combination thereof and the positioning method. Downlink PRS are measured by the UE based on the prioritization.

Abstract: A method of coordinating positioning signaling includes: identifying a first user equipment (UE) served by a base station and a second UE served by the base station, the base station being configured to send a base station positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for sending first UE positioning signals, and second times to the second UE, for sending second UE positioning signals, at least one of the first times being different from at least one of the second times; sending a first communication to cause the first UE to send at least a respective one of the first UE positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE positioning signals at each of the second times.

Abstract: Disclosed are techniques for wireless communications. In an aspect, a network entity obtains a user equipment (UE) capability report, the UE capability report including first and second UE capabilities, the first UE capability indicating a capability of the UE to measure positioning signals in a first band, the second UE capability indicating a capability of the UE to measure positioning signals in a second band, and configures the UE with an indication of one or more downlink positioning signal resources for measurement by the UE based on a function of the first and second UE capabilities, the one or more downlink positioning signal resources being for transmission by one or more transmission/reception points (TRPs), each downlink positioning signal resource occupying a frequency region that is at least part of the first or second band.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a mobile device receives a timing synchronization offset parameter for a first cell of a set of cells, wherein the timing synchronization offset parameter represents a difference between a system frame number (SFN) initialization time of the first cell and an SFN initialization time of a reference cell, and processes the timing synchronization offset parameter for the first cell based on the SFN initialization time of the reference cell having changed.

Abstract: An entity, such as the base station, user equipment (UE) or location server may determine that the UE should be configured with a measurement gap for intra-frequency positioning measurements outside the downlink (DL) bandwidth part (BWP) of the UE. The determination may be based several factors including whether the DL BWP is less than the available bandwidth for the positioning signals transmitted by the base station, with the same or differing numerologies, if a number of resource blocks for the DL BWP is less than a minimum number of resource blocks required by the UE, or if the DL BWP is less than a minimum fraction of a total available bandwidth of the DL PRS signals, or based on a desired positioning accuracy of the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives a DRX configuration, receives a reference signal resource configuration, determines, at least based on the DRX configuration and the reference signal resource configuration, whether an overlap exists between a reference signal occasion of a plurality of reference signal occasions of the reference signal resource configuration and an active time of the DRX configuration, receives or transmits at least based on a determined overlap, at least a first reference signal in the reference signal occasion, and receives or transmits, while remaining in an active state of the DRX configuration, at least based on the determined overlap, at least a second reference signal in remaining reference signal occasions of the plurality of reference signal occasions after expiration of the active time.
