摘要： A method is implemented by a measuring node in a wireless communication system. The method includes performing positioning measurements at the measuring node on positioning signals that the measuring node receives from geographically separated transmission points, TPs, (20) of a shared cell during different respective positioning occasions offset in time. The positioning signals are based on the same cell identifier. The method also includes, at the measuring node, associating (220) a result of each measurement with the cell identifier as well as information indicating the timing of each positioning occasion during which the measuring node received a respective positioning signal used for that measurement. Finally, the method includes determining (230) at the measuring node, or assisting another node in determining, a target device's position based on the results of the measurements and the association.

摘要： Examples disclosed herein relate to the scheduling and transmission of timing measurements between mobile computing devices in an area to determine the devices' locations. A bulk fine timing measurement (BFTM) allocation message is generated by a scheduling mobile computing device that identifies other mobile computing devices in the area. The BFTM allocation message generated by the scheduling mobile computing device indicates a time of delivery (TOD), a scheduling order for the identified mobile computing devices, and a contention-free period for the mobile computing devices to transmit the timing measurement messages.

摘要： A method of determining a position of at least one transceiver node comprises, anchor node by anchor node, transmitting respective positioning frames suitable for reception by a transceiver node and by the other anchor nodes. The transceiver node receives the positioning frames transmitted by the anchor nodes and ascertains respective times of reception for each. A solver stage determines the coordinates (x s , y s , z s ) of the respective transceiver node and the time t s of transmission of the first positioning frame by an anchor node of first rank in the positioning sequence by numerically solving a non-linear system of at least five equations.

摘要： A system for estimating the location of a mobile device is discussed herein. In one embodiment, the system can include a mobile device having a processor and a receiver, and a network of transceiver devices. The transceiver devices can be paired into multiple transceiver pairs of transceiver devices within communication range. The mobile device and transceivers can transmit a range request (REQ) packet by one transceiver in a pair; receive the REQ packet by another transceiver in the pair; transmit a range response (RSP) packet by the another transceiver; receive REQ packets by the mobile device; and receive RSP packets by the mobile device. The system is configured to estimate the differences of distances from the mobile node to the first and the second transceiver node in pairs; and to determine a location of the mobile device based on the estimated distance differences of devices.
