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: Techniques for determining a location of a mobile device are provided. An example of a method according to the disclosure includes determining, on the mobile device, beam identification information for one or more radio beams, transmitting, with the mobile device, the beam identification information to a network node, receiving, at the mobile device, positioning reference signal beam information for one or more positioning reference signals, generating, with the mobile device, one or more receive beams based on the positioning reference signal beam information, obtaining, with the mobile device, at least one measurement from at least one of the one or more positioning reference signals, and facilitating location determination of the mobile device at a location-capable device based at least in part on the at least one measurement.

Abstract: In a wireless network in which beams are transmitted by base stations, a beam relation database may be produced by crowdsourcing known positions of UEs and associated information related to beams received by the UEs at these positions. The beam information, for example, may include a beam identifier and cell identifier, and may further include measured signal parameters, such as Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ). The beam relation database may be used by a network or the UE to determine a position of a UE based on beams that are detected by the UE. The position fix may be an initial position fix that may be used to generate assistance data for the UE. Additionally, the beam relation database may be used to identify relevant measurement objects in the assistance data based on beams that are detected by the UE.

Abstract: A user equipment (UE) includes a processor configured to: send a first signal but not a second signal in response to the first and second signals being scheduled for concurrent transmission and available power for transmission of the first signal for the concurrent transmission being insufficient for detection of the first signal, the first signal being a first radio access technology (RAT) positioning reference signal; set a power sharing mode of the UE to a static power sharing mode; indicate that the UE is in a single-uplink operating mode with respect to the first RAT and the second RAT; and/or select a second-RAT TRP, for receiving the second signal, that has a maximum UE transmission power no greater than a threshold power in response to the initiation of the positioning session.

Abstract: Methods and systems are disclosed for concurrent transmission or resource blocks allocated to a mobile device for transmission in uplink communication channels. In particular implementations, a mobile device may tune local oscillators and/or apply filtering of radio frequency transmission to reduce or mitigate intermodulation distortion potentially affecting one or more radio frequency receiving functions.

Abstract: A User Equipment (UE) may receive a coverage 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: Methods and apparatuses are described relating to changes in an antenna configuration of a multi-antenna radio frequency (RF) transceiver between reference signal occasions. In one set of examples, a first antenna configuration at a first reference signal occasion of a first RF transmitter is stored, and if the antenna configuration has changed by the time a second reference signal occasion of the first (same) RF transmitter begins, the antenna configuration is switched back to the first antenna configuration. In another set of examples, compensation data to enable compensation between the first antenna configuration used to measure a first reference signal of a reference RF transmitter and a second antenna configuration used to measure a second reference signal of a neighboring (different) RF transmitter is retrieved and used when computing a time difference between the first and second reference signals.

Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.
