    Abstract: A User Equipment (UE) may receive a coverace mode transition request at a first time and upon determining that the coverage mode transition request includes a request to transition to an Enhanced Coverage (EC) mode, the UE may determine, based on parameters in the coverage mode transition request, an expected communication delay for transmission of a Reference Signal Time Difference (RSTD) measurement report The UE may initiate transmission of the RSTD measurement report for the positioning measurement session at a second time not exceeding a specified RSTD measurement time. The second time may precede an RSTD measurement timeout time for the positioning measurement session by at least the expected communication delay. Disclosed embodiments also pertain to communication of the expected communication delay between a Location Server (e.g. Evolved Serving Mobile Location Center) and a Base Station (e.g. evolved NodeB) using Long Term Evolution Positioning Protocol Annex (LPPa) messages.

    Abstract: Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including a method, performed at a first processor-based wireless device, that includes transmitting at a first time instance, from the first wireless device to a second wireless device, a wireless message including message content, and dynamically determining an adjustable timeout interval based, at least in part, on one or more network characteristics associated with a network comprising the first and/or second wireless devices. The method further includes transmitting at least one subsequent wireless message including at least some of the message content of the wireless message upon a determination that an acknowledgement message responsive to the wireless message transmitted at the first time instance was not received at the first wireless device within a time period, subsequent to the first time instance, greater or equal to the determined adjustable timeout interval.

    Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in which the UE evaluate available positioning methods based on one or more criteria to determine a prioritized positioning method and provides an indication of the prioritized positioning method to a location server. The UE may additionally provide an indication of the criteria upon which the prioritized positioning method was determined. The UE may send the indication of the prioritized positioning method before the UE performs the positioning measurements and the location server may accept or reject the prioritized positioning method. The UE may alternatively send the indication of the prioritized positioning method and the criteria used in the priority determination after the UE performs the positioning measurements. The location server may use the prioritized positioning method and the criteria used in the priority determination, e.g., in subsequent positioning requests for the UE.

    Abstract: Certain aspects of the present disclosure provide techniques for enhancing vehicle operations safety using coordinating vehicle platooning or enhancing platooning safety against location spoofing attacks. In one example, a source user equipment (UE) detects a potential spoofing event associated with location information being altered in an unauthorized manner, the source UE may transmit a request to a platoon control system (PCS) to join a vehicle platoon. In another example, a first UE associated with a lead vehicle in an existing platoon may detect a potential spoofing event associated with location information being altered in an unauthorized manner. The lead vehicle may transmit to a second UE of another vehicle in the platoon an indication of the detection and a request to exchange the respective roles in the platoon. The PCS may also monitor the conditions of the first and the second UEs, and arrange for the platoon reorganization.

    Abstract: Methods and systems for wireless communication are provided. In one example, a mobile device is configured to: obtain beam support information of a plurality of cells; perform measurements of one or more signals at the mobile device based on the beam support information of the plurality of cells to support a location determination operation for the mobile device; and transmit results of the measurements of the one or more signals to at least one of a location server or to a base station to support the location determination operation. The beam support information may include: a number of beams supported at each cell of the plurality of cells, information to identify each beam of the number of beams supported at the each cell, beam width information of the each beam, and/or Positioning reference Signals (PRS) codebook information which encapsulates the beams which are enabled along various elevation and azimuth angles.
