Abstract: A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.

Abstract: Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the first bandwidth.

Abstract: A user equipment (UE) and a Secure User Plane Location (SUPL) Location Platform (SLP) support a SUPL positioning session for at least one uplink or uplink-downlink position method, such as uplink Angle of Arrival or multi-Round Trip Time. To support SUPL positioning for uplink or uplink-downlink position methods, the UE provides an identifier for a serving Access and Mobility Management Function (AMF) and an identifier for the UE to the SLP in a SUPL message. The SLP may exchange positioning messages with a serving base station for the UE using the identifier for the serving AMF and the identifier for the UE. The exchange of positioning messages may enable the SLP to request the serving base station to instigate transmission of uplink positioning reference signals by the UE which may be a key enabler for an uplink or uplink-downlink position method.

Abstract: An entity in a wireless network is configured to increase transmission of a positioning reference signal (PRS) at each of a plurality of transmitters, where the increase in transmission of PRS at each of the plurality of transmitters is coordinated to avoid interference to or from non-PRS transmission in the wireless network. The increase in the transmission of PRS may be performed by a server, such as a location management function (LMF) or location management component (LMC), a base station, such as a gNB, ng-eNB, or eNB, or by a combination of the server and base station. The entity may determine the increase in transmission of the PRS in response to location requests for a plurality of user equipments (UEs), notification reports from a plurality of base stations, or requests for increased PRS from a plurality of UEs.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report measurements of a signal transmitted by a base station via a waveform. Based on the waveform, the base station may determine a position of the UE. The UE may measure the signal in a frequency band, where additional signaling in an adjacent frequency band causes interference on the signal. The UE may determine characteristics for measuring the signal based on the interference and may generate samples of the signal based on the measurement characteristics. Additionally, the UE may identify one or more antennas for measuring the signal and generate the samples based on the identified antennas. The UE may transmit the waveform report to the base station based on the samples. In some cases, the waveform may be based on a fractional symbol reporting scheme or a time mask with an offset and sampling rate.

Abstract: Methods and techniques are described for limiting a size of LTE Positioning Protocol (LPP) messages in a location session between a user equipment and location server. In one embodiment, a first device sends a first LPP message to a second device, indicating that the first device is capable of receiving segmented LPP messages. Subsequently, the first device receives a plurality of LPP message segments from the second device comprising one or more non-final LPP message segments and a final LPP message segment, where each LPP message segment includes a “non-final” or “final” indication. The first device stores the non-final LPP message segments and processes the LPP message segments after receiving the final LPP message segment. Prior to sending the first LPP message, the first device may receive an LPP message from the second device indicating the second device is capable of sending segmented LPP messages.

Abstract: Disclosed are methods for aiding a mobile device in the acquisition of positioning reference signals (PRSs) transmitted in a cellular network in support of OTDOA positioning. In one implementation, a mobile device receives an offset parameter from a location server indicative of a difference in timing between transmission of a first PRS positioning occasion for a reference cell and transmission of a second PRS positioning occasion for a neighboring cell that supports multiple PRS configurations, where the second PRS positioning occasion is for a PRS configuration with a longest periodicity. The mobile device may determine an expected timing of PRS positioning occasions for other PRS configurations for the neighboring cell based on the offset parameter and may measure a Reference Signal Time Difference for the neighboring cell using the expected timing.

Abstract: An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.

Abstract: Techniques are disclosed in which generic position methods in a wireless network allow positioning of a target user equipment (UE) that is served by any one (or more) of a number of different Radio Access Technologies (RATs) and that allow measurements by the UE of access nodes belonging to different RATs and/or measurements of the UE by access nodes for different RATs. With a generic position method, a common set of procedures, messages, and parameters may be defined that are applicable to multiple RATs and that do not require a location server to know in advance the serving RAT for a target UE.
