Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeBs measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.

Abstract: Methods and systems for wireless communication are provided. In one example, a method comprises: receiving, by a mobile device, a radio beam, the radio beam being a directional beam that propagates along an angle of departure with respect to an antenna that transmits the radio beam; identifying, by the mobile device, at least one of: the radio beam or a base station that operates the antenna; determining, by the mobile device, a position of the mobile device based on identifying at least one of the radio beam or the antenna of the base station; and outputting, by the mobile device, the position of the mobile device.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE receives a positioning configuration, the positioning configuration including at least an identifier of a first downlink reference signal from a neighboring cell to be used for estimating a downlink path loss or determining an uplink spatial transmit beam, determines that a first downlink reference signal received from the neighboring cell cannot be used for estimating the downlink path loss or determining the uplink spatial transmit beam, in response to the determination, estimating the downlink path loss or determining the uplink spatial transmit beam based on a second downlink reference signal received from the neighboring cell or a serving cell, and transmits an uplink reference signal for positioning based on the estimated downlink path loss, the determined uplink spatial transmit beam, or a combination thereof.

Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques for implementing positioning schemes based on a waveform report are described. A wireless device may receive a waveform reporting request instructing the wireless device to measure a waveform. The wireless device may identify a set of reporting parameters for sampling the waveform, receive the waveform, and generate samples of the waveform based on the set of reporting parameters. The wireless device may transmit a waveform report that is generated based on the samples.

Abstract: Techniques are provided for determining a path loss for semi-persistent SRS-for-positioning if the path loss resource set is not updatable through a MAC CE. An example method according to the disclosure includes receiving, from a serving base station, a medium access control control element, determining a spatial relation reference of a first sounding reference signal resource, setting a path loss reference for a sounding reference signal for positioning resource set to the spatial relation reference if the spatial relation reference is not an uplink reference signal, setting the path loss reference equal to a reference system resource from a synchronization signal block the user equipment utilizes to obtain a master information block if the spatial relation reference is an uplink reference signal, and transmitting the resources of the sounding reference signal for positioning resource set based at least in part on the path loss reference.

Abstract: Disclosed are techniques for transmitting and receiving an extended narrowband positioning reference signal (NPRS) sequence. In an aspect, a base station generates the extended NPRS sequence and transmits, to at least one user equipment (UE) over a wireless narrowband channel, the extended NPRS sequence. In an aspect, a UE receives, over the wireless narrowband channel, an NPRS of a first subset of the extended NPRS sequence and measures the NPRS of the first subset of the extended PRS sequence. In an aspect, the extended NPRS sequence may be a function of a plurality of slot numbers of a plurality of slots of a plurality of sequential radio frames and a plurality of symbol indexes of a plurality of symbols of a single physical resource block.

Abstract: Positioning of a UE is supported in a Radio Resource Control (RRC) Inactive state. The UE receives a request for periodic or triggered location and enters the RRC Inactive state. When an event is detected, the UE sends an RRC Resume Request to a gNB that includes an indication of the event. The indication may be an event report that may include downlink positioning measurements. The gNB forwards the event report to a location server, and may later receive and return an event report acknowledgement to the UE in an RRC Release. The indication may instead trigger uplink positioning, with the base station sending an uplink Sounding Reference Signal (SRS) configuration to the UE in an RRC Release, causing the UE to transmit uplink SRS signals to be measured by gNBs. For uplink related position methods like RTT, the gNB can receive both types of indication.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for on-demand positioning. For example a method may include transmitting a request to participate in a UE positioning procedure, wherein the request indicates one or more parameters to be used by a location server in coordinating one or more base stations (BSs) to participate in the UE positioning procedure, and receiving signaling from the location server configuring the UE to participate in the UE positioning procedure.

Abstract: Latency in location of a user equipment (UE) is reduced by requesting and scheduling the location of the UE in advance of the time of when it is needed. A positioning request from an external client or the UE may indicate the time that the location is to be determined or measured. A location management function (LMF) may manage and coordinate location measurements for the UE prior to the location determination time. The LMF may schedule downlink and/or uplink measurements to be performed at the desired time. Either the LMF or a location server associated with a serving base station for the UE may be assigned to receive positioning measurements and obtain the location of the UE. The location server or LMF may send the location to the UE or the external client. User plane transport may be used to further reduce latency.
