Abstract: Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including an example method to facilitate position determination operations that includes producing, by a location transmission unit (LTU) configured for downlink-only communication, one or more subframes comprising one or more LTU broadcast positioning reference signals. The LTU is detectable by at least one mobile wireless device based on LTU broadcast control signals, with at least some of the LTU broadcast control signals being transmittable by a different wireless node than the LTU. The method also includes transmitting, by the LTU, the one or more LTU broadcast positioning reference signals usable for determination of a position of at least one mobile wireless device, with the one or more LTU broadcast positioning reference signals being detectable by the at least one mobile wireless device.

Abstract: Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning for a target device includes exchanging positioning messages that support a plurality of positioning methods between the target device and a location server. The positioning message may include common parameters applicable for all positioning methods. One of the positioning messages may be a Request Assistance Data message to request assistance data for a first positioning method, wherein the common parameters for the Request Assistance Data message includes an approximate location of the target device determined using a different positioning method. Another positioning message may be a Provide Assistance Data message to provide assistance data that is not in response to a request for assistance data, wherein the common parameters for the Provide Assistance Data message may include an approximate location of the target device or a current time.

Abstract: Disclosed embodiments pertain to a method of generating a Positioning Reference Signal (PRS) sequence for a system comprising a plurality of physical transmitting antenna elements serving a single cell. In some embodiments, the method may comprise: assigning a distinct Physical Antenna Port (PAP) identifier (ID) to a subset of the plurality of physical transmitting antenna elements; and generating PRS sequences for the subset of the plurality of physical transmitting antenna elements, wherein each PRS sequence corresponds to a physical transmitting antenna element in the subset of the plurality of physical transmitting antenna elements, and each PRS sequence has a corresponding frequency shift based, at least in part, on the PAP ID (h) of the corresponding physical transmitting antenna element.

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: Methods and techniques are described for economically supporting a cluster of transmission points (TPs) that serve as positioning only beacons in a wireless network. A TP may broadcast a positioning reference signal (PRS) for positioning of a user equipment (UE) using the 3GPP OTDOA method for LTE wireless access. TPs are controlled by a TP Controller (TPC) that may function as an evolved NodeB (eNB) or Home eNB. A TPC may configure (or retrieve) PRS parameters in (or from) a controlled TP, may provide an accurate time reference to the TP and may be connected to the TP using a LAN or WLAN. A location server such as an E-SMLC may retrieve information for TPs, such as PRS parameters, TP location, and TP identity, from a controlling TPC, e.g. using the LPPa protocol. An E-SMLC may access a TPC via an MME to which the TPC may be connected.

Abstract: Methods, apparatuses and/or articles of manufacture, which may be employed in a mobile device and/or in a location server, enable acquisition assistance at the mobile device. In at least one implementation, which is not intended to limit claimed subject matter, acquisition assistance may include expected Doppler frequency shift and expected code phase in the case of a particular Global Navigation Satellite System (GNSS) satellite vehicle, as well as a search window for each of these, and a confidence value. The confidence value may indicate the likelihood of detecting signals from the satellite vehicle at the current expected location of the mobile device and within the given search windows and may enable one or more of faster location estimation, reduced battery consumption, and detection of weaker satellite signals.

Abstract: Techniques are discussed for supporting positioning with ambiguous wireless cells. An ambiguous cell may employ a Distributed Antenna System (DAS), one or more Remote Radio Heads (RRHs), repeaters or relays, or may broadcast the same Positioning Reference Signal (PRS) as another nearby cell. In example techniques, measurements of a radio source in an ambiguous cell (e.g. a DAS antenna element or RRH) may be used to identify the measured radio source. The measurements may be for the Observed Time Difference of Arrival (OTDOA) position method or the Enhanced Cell ID (ECID) position method. The determination of the measured radio source for an ambiguous cell may be used to improve a location estimate for a user equipment (UE).

Abstract: A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.
Abstract translation: 与无线电接入网络（RAN）通信的用户设备（UE）向网络实体（例如，MSC / SGSN）发送用于向客户端实体定期报告UE位置的请求。 在请求被批准之后，MSC / SGSN向RAN发送信令以发起针对UE的周期性位置报告。 RAN可以请求定位中心（例如，SAS）向UE发送辅助数据。 RAN可以协调和控制周期性位置报告，或者可以将控制传递给定位中心。 对于每个位置报告，UE向RAN发送位置信息（例如由UE进行的测量或由UE计算的位置估计）。 如果UE发送测量，则SAS计算位置估计。 RAN然后将UE的位置估计发送给MSC / SGSN，MSC / SGSN将位置估计转发给客户实体。

Abstract: Disclosed embodiments pertain to the obtaining and utilization of Observed Time Difference of Arrival (OTDOA) assistance data. Cell timing information obtained based on measurements by a Mobile Station (MS) of neighbor cells may comprise cell timing offsets of the neighbor cells relative to a serving cell for the MS. OTDOA assistance data may be generated, where the OTDOA assistance data may comprise an OTDOA assistance data reference cell and a cell timing offset between the serving cell and an OTDOA assistance data reference cell, the reference cell being selected based on the received neighbor cell measurements. Embodiments disclosed also pertain to methods on an MS for performing measurements of neighbor cells comprising cell timing information for neighbor cells by requesting idle periods with a desired length from a base station to perform the measurements, and performing the requested measurements upon receiving confirmation that the idle periods have been configured.

Abstract: A large volume of location related information, e.g., assistance data or location information, is transferred in separate messages between a server and a target by segmenting the location related information into a plurality of messages. If the connection between the server and target is released prior to completion of the transfer of the location related information, the transfer is resumed by sending the remaining messages after connection is reestablished. Each message is sent after receiving an acknowledgement of receipt. Thus, both the server and target can control the flow of the transfer by delaying the sending of one or more messages or delaying the sending of the acknowledgements of receipt.
