Abstract: A user equipment (UE) is preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations. The UE receives a base station almanac including position information and identifies of local base stations. Using the PRS configurations and information from the base station almanac, the UE receives PRS signals from a first set of base stations. The UE may also receive cell-specific reference signals (CRS) from a second set of base stations. The UE performs location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.

Abstract: The present disclosure relates to pseudo-randomization of unused resources at a medium access control layer (MAC) of a user equipment (UE). For example, the disclosure presents a method and an apparatus for determining that an uplink (UL) resource grant, associated with a first radio access technology (RAT), for the UE results in unused resources where there are a greater number of resources than available data for transmission at the UE, wherein the UE is configured to receive information associated with a second RAT, and wherein the first RAT is different from the second RAT, populating the unused resources, at a medium access control (MAC) layer, with pseudo-randomized bits, and transmitting at least a portion of the available data and the populated unused resources using the UL resource grant associated with the first RAT. As such, pseudo-randomization of unused resources at a medium access control layer (MAC) of a UE may be achieved.

Abstract translation: 本公开涉及在用户设备（UE）的媒体接入控制层（MAC）处对未使用资源的伪随机化。 例如，本公开提供了一种用于确定与用于UE的第一无线电接入技术（RAT）相关联的上行链路（UL）资源许可的方法和装置，其导致未使用的资源，其中存在比可用资源更多的资源数量 用于在UE处传输的数据，其中所述UE被配置为接收与第二RAT相关联的信息，并且其中所述第一RAT与所述第二RAT不同，在介质访问控制（MAC）层处填充所述未使用的资源， 并且使用与第一RAT相关联的UL资源许可来发送可用数据和填充未使用资源的至少一部分。 因此，可以实现在UE的介质访问控制层（MAC）处的未使用资源的伪随机化。

Abstract: Disclosed embodiments pertain to combining Reference Signal Time Difference (RSTD) measurements from partial measurement sessions that result when a single measurement session is interrupted by one or more interruption events including Out of Service (OOS) or Inter-Frequency Handover (IFH) events. In some embodiments, first Time Of Arrival (TOA) measurements of cellular signals during a plurality of discontiguous partial measurement sessions separated by one or more interruption events may be obtained. Second TOA measurements based on a reference time source may be obtained for a plurality of the first TOA measurements from at least two partial measurement sessions. A cell associated with a second TOA measurement may be selected as a reference cell and for each non-reference cell associated with a second TOA measurement, a corresponding RSTD measurement may be obtained relative to the selected reference cell.

Abstract: A mobile station that is wirelessly linked to a wearable device, receives a request to initiate a location session from the wearable device, e.g., which may be in the form of an emergency call. The mobile station determines whether the location of the mobile station may be used as a location of the wearable device, e.g., by determining if the wearable device is proximate to the mobile station. For example, the mobile station may check to see if the mobile station is wirelessly linked to a wearable device through a wireless personal area network (WPAN). The mobile station initiates the location session for the wearable device with a location server. If the location of the mobile station may not be used as a location of the wearable device, the location session for the wearable device does not use position information obtained from the mobile station.
