The positioning processing method includes: receiving a first positioning reference signal from a first terminal device; receiving a second positioning reference signal from a second terminal device bound to the first terminal device; determining position information of the first terminal device based on the first positioning reference signal and the second positioning reference signal; and sending the position information to at least one of the first terminal device or he second terminal device.

A method of transmitting a sounding reference signal (SRS) for positioning includes: obtaining, at a user equipment (UE), a plurality of SRS transmission parameters; and transmitting SRS for positioning from the UE in accordance with the plurality of SRS transmission parameters while the UE is in an unconnected state, relative to a communication network, or an inactive state.

Disclosed herein are methods, devices, and systems for determining geographic location and time. In one embodiment, a radio and a processor configured for deriving a first signal tone originating from a first remote antenna located at a first location; deriving a second signal tone originating from a second remote antenna located at a second location; deriving a third signal tone originating from a third remote antenna located at a third location; determining a first frequency and a first phase at a first time of the first signal tone; determining a second frequency and a second phase at a second time of the second signal tone; and determining a third frequency and a third phase at a third time of the third signal tone. The method further includes determining a geographic location based on the first, second, and third frequencies; the first, second, and third phases; and the first, second, and third locations.

A positioning operation for a user equipment (UE) involves a two-step process having a coarse positioning followed by a refined positioning. The coarse positioning can be based on periodic reference signals from a first set of network nodes. A refined positioning specific to the UE is configured based on the coarse positioning. The refined positioning can include targeted transmissions of reference signals to the UE by a second set of network nodes.

A method and a system for ultra high frequency communication with and location of a portable device for “hands-free” access to a motor vehicle, the motor vehicle having an on-board communication device comprising an ultra high frequency transceiver, an electrical power supply source and at least one antenna, the motor vehicle including a first arrangement, in which the transceiver is connected to the antenna, and a second arrangement, in which the transceiver is disconnected from the antenna. The transceiver is connected to an attenuation module located at a predetermined distance from the transceiver. The attenuation module includes an impedance of predetermined value connected to ground. The predetermined distance between the transceiver and the attenuation module, as well as the predetermined value of the impedance, defining a locating area of the portable device in and around the motor vehicle.

The present disclosure provides cell reselection method, including: a terminal device receivers network slice information supported by a neighboring cell, the network slice information comprising single network slice selection assistance information (S-NSSAI) or an S-NSSAI set; and the terminal device perform cell reselection based on the network slice information. The present disclosure also provides another cell reselection method, an electronic device and a storage medium.

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.

Device, method and computer program to make better use of measurements of received signals for determining location are provided. A client device is configured to receive a signal that contains a reference symbol modulated onto a plurality of subcarriers. The client device determines a plurality of weights based on the reference symbol and line-of-sight channel frequency responses for the subcarriers, so that each of the plurality of weights is associated with one of the subcarriers. The client device determines a gain associated with the received signal using the plurality of weights. A network device may receive from the client device information indicative of gains, wherein a gain indicates a signal strength at which the client device was able to receive a respective signal. The location of the client device may be determined by using information about network device locations, transmission directions, and the gains.
