  • Publication number: 20190268725
    Abstract: Techniques are discussed herein for efficiently supporting broadcast of location assistance data (AD) in a wireless network to assist in locating a user equipment (UE). A location server (LS) may send some location AD, which may be optionally ciphered, to base stations for broadcast in cells supported by the base stations. Capability information provided by a UE to the LS indicating a level of support by the UE for receiving broadcast AD and supporting ciphering may enable the LS to determine whether, and what type of, additional AD needs to be sent to the UE by point to point means. An LS may use capability information received from a large number of UEs to assist in determining the types of location assistance data to be broadcast and usage of ciphering.

  • Publication number: 20190261368
    Abstract: A reference signal may provide for enhanced bandwidth utilization to enable highly accurate position determination with relatively low bandwidth. For a given allocated bandwidth, a reference signal may use of only a portion of the allocated bandwidth by using plurality of sub-bands. In some cases, the sub-bands may be near the edges of the allocated band to maximize Gabor bandwidth.

  • Publication number: 20190230475
    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.

  • Publication number: 20190190806
    Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.

  • Publication number: 20190166453
    Abstract: Angle of arrival (AOA) and differential AOA (DAOA) positioning for a user equipment (UE) is enhanced by using the UE's inertial sensors to track UE motion and change in angular UE orientation. UE location may be computed, by the UE or a location server, using triangulation for AOA measurements relative to a global reference frame or using multilateration for DAOA measurements. The computed UE location may remain accurate even when the UE is moving while obtaining measurements. The UE can also use AOA and DAOA measurements using 3D angles to increase accuracy when the UE and measured base stations are not in the same horizontal plane. 3D angles can also be used to identify whether the UE is close to a serving base station to improve accuracy further. Various non-AOA measurements may also be used to supplement AOA and DAOA measurements.

  • Publication number: 20190110271
    Abstract: Techniques described herein provide ways in which a quantity of signaling may be limited between a user equipment (UE) and a location server (LS) for a location session and a positioning protocol such as LPP or LPP/LPPe. The positioning protocol may be enhanced to allow the LS to indicate to the UE a limit on the overall size of assistance data (AD) that the UE can request and/or a limit on the overall amount of location information (LI) that the UE can return. A recipient UE can then prioritize any request for AD such that more important AD should fit within the size limit. The recipient UE can also prioritize returned location measurements such that more useful measurements are included in a message to the LS that is compliant to the limit indicated by the LS.

  • Publication number: 20190110225
    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.

  • Publication number: 20190053280
    Abstract: A user equipment (UE) may determine that a channel, such as a downlink channel or an uplink channel, and a positioning reference signal (PRS) occasion are scheduled for a common set of resources, such as a common frequency, a common time, and/or the like. This may result in the UE being unable to receive the PRS and/or process the PRS as a result of receiving the channel. In some aspects, the UE may determine that a PRS collides with a channel, and may perform a collision response action, such as dropping at least a portion of the channel, based at least in part on determining that the PRS occasion collides with the channel.
