    Abstract: Methods, systems, computer-readable media, and apparatuses for using a small cell as a reliable crowd-sourcing agent are presented. In some embodiments, a small cell installed at a known location may observe one or more wireless signals at the known location, wherein the small cell comprises a built-in network listen receiver for observing cellular downlink signals. Subsequently, the small cell may provide, to at least one crowdsourcing server, information that identifies the location and describes one or more detected properties of the one or more observed wireless signals. In at least one arrangement, the information provided to at least one crowdsourcing server is a Positioning Reference Signal (PRS) configuration based on an observed LTE downlink signals. In at least one arrangement, the information provided to at least one crowdsourcing server is configured to be used by the at least one crowdsourcing server in providing position assistance information.

    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: Techniques are discussed for conveying frequency error characteristics for a plurality of cell transceivers from a server to a mobile device to enable the mobile device to determine an optimum or near optimum period of coherent integration of a downlink signal from one or more of the plurality of cell transceivers based on the frequency error characteristics. The coherent integration of the downlink signal may be to support a downlink terrestrial positioning method such as the Observed Time Difference of Arrival (OTDOA) method for Long Term Evolution (LTE) and the downlink signal may be a Positioning Reference Signal (PRS). A mobile device may perform downlink signal integration for longer periods than the optimum period for coherent integration by combining coherent integration results using non-coherent integration. The optimum period may achieve maximum or near maximum signal to noise ratio.

    Abstract: Systems and methods are presented for discovering a local location server associated with a local provider based on a relationship between the local provider and another regional/global provider. A mobile device discovers the local provider and queries a home location server which returns the address of a regional/global location server associated with the regional/global provider. A mobile device then queries the regional/global location server to discover the local location server and may then access the local location server to obtain location services. The method may be employed with the OMA SUPL location solution wherein the home location server may be an H-SLP and the local and regional/global location servers may be D-SLPs.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, an integrated access and backhaul (IAB) node sets a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters, receives, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters, and transmits, to a positioning entity, a report indicating a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing.

    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.
