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.

Abstract: Certain aspects of the present disclosure provide techniques for coordinating vehicle platooning with V2X assistance. The techniques generally include: a first vehicle associated with a source UE transmitting a request to a base station to join a vehicle platoon. The request indicates at least one of: an occupancy parameter of a first vehicle associated with the source UE; an autonomy level of the first vehicle; or a travel preference parameter. The occupancy parameter may include a number of passengers, seating positions of passengers, and other occupancy information pertaining safety and prioritization. The autonomy level enables vehicles of similar autonomy to form a platoon that optimizes headways, thus minimizing fuel consumption due to air resistance. The travel preference parameter may include a preferred speed of the source UE. The source UE may receive a response message indicating confirmation that the first vehicle is allowed to join the vehicle platoon.

Abstract: Disclosed are techniques for performing positioning measurements at a mobile device during a positioning session with a serving cell. In an aspect, the mobile device determines to trigger a coverage-enhanced (CE) mode before a positioning session timeout for the positioning session expires, continues performance of the positioning measurements during the positioning session with the serving cell while the mobile device remains connected to the serving cell due to the triggered CE mode, determines whether the positioning measurements have been completed or the positioning session timeout has expired, and responsive to the determination that the positioning measurements have been completed or that the positioning session timeout has expired, reports, to a network entity in the wireless communications network, actual handover measurements to enable the network entity to make a handover determination.

Abstract: In an aspect, to perform inter-frequency measurements by a user equipment (UE) in a carrier aggregation mode, the UE receives assistance data identifying one or more reference signal occasions for one or more neighbor cells, receives information identifying one or more subframes during which the one or more neighbor cells do not carry data transmissions, identifies, for a first reference signal occasion of the one or more reference signal occasions, a first subframe of the one or more subframes that overlaps the first reference signal occasion, tunes, during the first subframe, a first active carrier receiver of a plurality of active carrier receivers away from a first frequency on which the first subframe is transmitted to a second frequency on which the first reference signal occasion is transmitted, and measures, by the first active carrier receiver, the first reference signal occasion on the second frequency during the first subframe.

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.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Abstract: In various implementations, methods, apparatuses, and computer-readable media are described for optimizing tune away carrier selection in a wireless communications system for position determination. The selection of a tune away carrier can be based on, for example, timing information related to pre-scheduled periods for receiving wireless position measurement signals, timing information related to pre-scheduled downlink data reception, timing information related to pre-scheduled uplink data transmission, etc.
