For determining a temporal reference and/or at least one spatial reference, in a communication system comprising a plurality of gathering gateways configured to transmit beacons, a device performs for each beacon: obtaining (502) therefrom information on current geolocation of the gathering gateway that transmitted said beacon; obtaining (503) therefrom information representing a communication technology used for determining said current geolocation; and obtaining (504) therefrom information indicating whether said current geolocation was determined by internal means or by external means. The device then uses (509) the information thus obtained for determining the temporal reference for synchronizing in time and frequency said device and/or the spatial reference or references for determining the geolocation of said device.

Proposed are an apparatus and a method for estimating the position of a target terminal within a mobile communication system. In general, a mobile communication system is composed of a base station and terminals. In the present invention, one or more positioning devices are placed around a target terminal required to be positioned to measure a transmission signal of the target terminal, and accurately measures the position of the target terminal on the basis of the transmission signal. In the above process, the base station should connect a communication channel with the terminal for positioning of the terminal, and a method therefor is proposed. In particular, the present invention relates to a method for setting a terminal in a standby state to transmit an uplink signal. In addition, an operation and a protocol for positioning the target terminal are proposed.

The method further includes performing positioning or assisting performance of positioning based on the obtained high accuracy positioning information.

The assistance data (20) may be based on device-specific information. The device-specific information may for example include a subscription associated with the wireless device (12). The wireless device (12) may perform the RAT-dependent positioning based on assistance from the assistance data (20).

A method is disclosed. In various examples, the method may include receiving an instruction for generating a signal that comprises a ranging signal and a data signal, and transmitting the signal at least partially responsive to the instruction. In various examples the signal may be transmitted via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing. In various examples, the signal may include a pulse group comprising a first pulse having a first start time; and a second pulse having a second start time. The second start time may be an integer number of inter-pulse intervals plus an encoding delay after the first start time. The encoding delay may encode data.

The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Data may be encoded using the either positive-going phases or negative-going phases of the data pulses. The device may include a processor to decode the data at least partially responsive to the phases of the respective ones of the number of data pulses.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may transmit, to a network entity comprising a location server and/or base station, a positioning capability report that includes a set of positioning capability parameters for a radio resource control (RRC) connected state. The UE may enter an RRC unconnected state, the RRC unconnected state comprising an RRC inactive state or an RRC idle state. The UE may perform positioning reference signal (PRS) processing during the RRC unconnected state according to one or more positioning capability parameters from the set of positioning capability parameters for the RRC connected state.
