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: 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.

Abstract: Disclosed are techniques related to wireless communication system in which a network node (e.g., a base station, gNB, etc.) may be allowed to puncture a reference signal (RS) to deliver high priority data (e.g., URLLC data) to a user equipment (UE) that is not currently being served by the network node. The RS may comprise a puncturable subset and an unpuncturable subset. The puncturable subset may comprise resources of the RS that are allowed to be punctured, and the unpuncturable subset may comprise resources of the RS that are prohibited from being punctured. The network node may transmit the RS such that unpuncturable subset indicates whether or not the puncturable subset of the RS has or has not been punctured. In this way, the network node can quickly inform whether or not the RS has been punctured to carry high priority data.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

Abstract: A user equipment (UE) periodically obtains its location using UE based Observed Time Difference of Arrival (OTDOA). The location is based on Reference Signal Time Differences (RSTDs) measured by the UE for downlink (DL) signals transmitted by each of a plurality of base stations, and the most current Real Time Differences (RTDs) for pairs of base stations. The RTDs may be determined by the UE using the RSTD measurements and Round Trip Time (RTT) measurements determined by a network entity or by the UE. The RTDs may be determined less frequently than the UE location to reduce network and UE load. Location of the UE may be improved based on testing a rate of change for each of the RTDs. The RTD determination may be improved using measurements from a plurality of UEs.

Abstract: Disclosed are methods and apparatuses for providing configurable reference signal timing difference (RSTD) search windows for positioning. In an aspect, an RSTD search window is configured based on a positioning reference signal (PRS) configuration. The RSTD search window is provided to the UE. A plurality of PRS is transmitted from a network entity to a user equipment (UE), each PRS having the PRS configuration. The plurality of PRS are transmitted in a subset that is less than all subcarriers over a given bandwidth.

Abstract: A method of processing a satellite signal includes: receiving a satellite positioning system (SPS) signal, including an SPS data signal of unknown data content, from a satellite at a wireless communication device; receiving symbol indications, of determined symbol values, from a terrestrial wireless communication system at the wireless communication device; correlating the SPS data signal with a pseudo-random noise code to obtain first correlation results; and using the symbol indications and the first correlation results to determine a measurement of the SPS signal.

Abstract: Disclosed are techniques for performing positioning operations. In an aspect, a user equipment (UE) receives a downlink physical channel from a base station, the downlink physical channel received via one or more slots of one or more subframes of one or more radio frames, the downlink physical channel carrying user data and/or control information from the base station to the UE, receives, from the base station, an indication that the base station will transmit reference signals for positioning on the downlink physical channel, and performs a positioning measurement of a reference signal received on the downlink physical channel.
