Disclosed is a method for performing positioning by a user equipment (UE) in a wireless communication system including: receiving first assistance data including first reference cell information and first neighbor cell information from a first base station (BS) through a first frequency; receiving second assistance data including second reference cell information and second neighbor cell information from a second base station through a second frequency; receiving a positioning reference signal (PRS) on the basis of the first assistance data and receiving a discovery reference signal (DRS) on the basis of the second assistance data; performing measurement using the received PRS and the DRS; and reporting a measurement result to a serving BS.

Disclosed is a location information determining method and system for providing a variety of services based on a location. The location information determining method includes receiving cell information; and determining location information that matches the cell information as location information of a mobile terminal from a location information database that stores location information that matches a plurality of pieces of cell information, respectively.

A user equipment (UE) provides to a location server a recommendation or request for positioning technologies and methods that may be appropriate for the environment in which the UE is located. The UE may provide the recommendation or request may be a priority list of one or more specific positioning technologies, one or more specific methods of a positioning technology, a combination thereof. The UE based prioritization for positioning may be provided unsolicited or requested by the location server. The UE based prioritization for positioning may be provided as part of a message used in current positioning protocols, such as Long Term Evolution (LTE) Positioning Protocol (LPP), e.g., by ranking information elements (IEs) associated with each positioning technology and method in the body of the message or as part of a common IE.

The proposed solution includes the use of four reference bases on the ground at known positions, with a coded time signal transmitted by one of them which is retransmitted by the repeater station and received by each of the reference bases. Using two distinct sets of three reference bases it is possible to calculate the differences between two positions for the repeater station, assigning to the later changes in time, phase or frequency as well as temporal changes due to the signal propagation in the medium, for the respective elevation angles found for the repeater. It can be then identified which values attributed to the temporal changes produces a minimum difference between the two respective positions of the repeater station. The identified temporal change can be used for the correct determination of the repeater station and its use on pertinent applications.

A method includes obtaining signal information based on wireless signals communicated between an electronic device and a target device. The method also includes obtaining motion information based on movement of the electronic device. The method further includes identifying first location information based on the signal information, the first location information indicating whether the target device is within a field of view (FoV) of the electronic device. Additionally, the method includes identifying second location information based on the motion information and the signal information, the second location information indicating whether the target device is within the FoV of the electronic device. The method also includes determining that the target device is within the FoV or outside the FoV of the electronic device based on at least one of the first location information or the second location information.

A method of detecting location includes receiving, on a mobile device, a plurality of previously stored WiFi hotspots; detecting, on the mobile device, a plurality of surrounding WiFi hotspots; comparing the plurality of surrounding WiFi hotspots to determine one or more differences between the plurality of previously stored WiFi hotspots; determining the differences satisfy a difference threshold; sending the plurality of surrounding WiFi hotspots to a location lookup system; and receiving a response from the location lookup system.

A system and method for locating radio-frequency identification tags within a predetermined area. The method can incorporate sub-threshold superposition response mapping techniques, alone, or in combination with other methods for locating radio-frequency identification tags such as but not limited to time differential on arrival (TDOA), frequency domain phase difference on arrival (FD-PDOA), and radio signal strength indication (RSSI). The system can include a plurality of antennas dispersed in a predefined area; one or more radio-frequency identification tags; a radio-frequency transceiver in communication with said antennas; a phase modulator coupled to the ra-dio-frequency transceiver; and a system controller in communication with said transceiver and said phase modulator. Calibration techniques can be employed to map con-structive interference zones for improved accuracy.

Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method, at a processor-based mobile device, that includes determining a first set of candidate positions of the mobile device corresponding to a first time instance based, at least in part, on position data including a first set of identifiers decoded from signals including respective first one or more light-based communications received by the mobile device from a first one or more light devices, with the mobile device being located at a first location at the first time instance. The method further includes selecting at least one candidate position from the first set of candidate positions, in response to a determination that the first set of candidate positions includes more than one candidate position, in order to resolve positional ambiguity, based, at least partly, on further position data from further signals from one or more devices.

A method of measuring a location of a user equipment (UE) located indoors in a wireless network includes receiving signals from a plurality of access points (APs), performing training for machine learning using the received signals or information acquired from the received signals, setting a weight vector to be applied to a relevance vector machine (RVM) method using data subjected to the training for machine learning, and applying RVM regression to the set weight vector and measured strengths of the received signals and determining whether the signals received from the plurality of APs are line of sight (LOS) signals or non line of sight (NLOS) signals.
