A method for determining a location of a vehicle. The method includes obtaining, by a marker reader of the vehicle, a marker location from a signal emitted by a marker located in a vicinity of the vehicle. The marker location is provided relative to a known reference point. The method further includes obtaining vehicle location information relative to the first marker using at least one sensor disposed in the vehicle, and obtaining an estimate of the vehicle location relative to the known reference point, using the marker location and the vehicle location information.

Aspects of the disclosure provide a method for observed time difference of arrival (OTDOA) positioning. The method can include receiving from a serving cell of a first network assistance data for measuring time difference of arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network, receiving from the serving cell a gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, or a system frame number (SFN) offset of the first neighboring cell, and determining an SFN timing of the first neighboring cell based on the gap pattern for decoding the MIB of the first neighboring cell or the SFN offset of the first neighboring cell.

Provided is a method for sending an in-band positioning signal and in-band positioning system in a communication network. The system includes: a Position Management Station (PMS), arranged to manage one or more Position Service Stations (PSSs) and provide a synchronization reference clock for the one or more PSSs; a positioning center network element, arranged to provide position estimation information for a terminal based on position information of the one or more PSSs and send the position estimation information to the terminal; and the one or more PSSs, of which each PSS uses a same frequency band used by the communication network and is arranged to generate an in-band positioning signal for measuring a distance, regulate a sending clock of the in-band positioning signal according to a difference value between a local sending clock and the synchronization reference clock and send the in-band positioning signal to the terminal.

Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes transmitting a Request Assistance Data message to a location server, the Request Assistance Data message indicating at least one positioning method from a plurality of supported positioning methods. The Request Assistance Data message comprises common parameters that are applicable to all positioning methods indicated in the Request Assistance Data message. The common parameters comprise a serving cell identifier. Positioning for the target device further includes receiving assistance data sent in response to the Request Assistance Data message, and performing positioning based on the received assistance data.

Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes receiving a Request Location Information message that indicates at least one positioning method from a plurality of supported positioning methods. The Request Location Information message comprises common parameters that are applicable to all positioning methods indicated in the Request Location Information message. The common parameters comprise a quality-of-service (QoS), an indication of whether periodic location information is requested, an indication of whether triggered location information is requested, or any combination thereof. Positioning is performed in response to the Request Location Information message and can include determining a location estimate for a location of the target device.

A tag having a fixed physical location comprising a processor, a memory storing a first identifier, and a wireless communication interface configured to broadcast a first transmission including the first identifier. The processor is configured to receive, from the wireless communication interface, second identifiers of neighboring tags. The processor then configured to store the second identifiers of the neighboring tags in the memory and then modify the first transmission of the first identifier to include the second identifiers of the neighboring tags.

A station (STA) receives a schedule from a reference device in a wireless network. The schedule provides a measurement time for each of one or more wireless channels. The STA tunes to a first channel of the one or more wireless channels in accordance with the schedule. While tuned to the first channel in accordance with the schedule, the STA receives a first message from a first access point (AP). The first message, which includes a time-of-departure timestamp from the reference device, is time-stamped with a time-of-arrival timestamp. The STA receives an indication of a time at which the reference device received the first message from the first AP. The STA determines its position based in part on the time-of-departure timestamp, the time-of-arrival timestamp, and the time at which the reference device received the first message.

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.
