Abstract

A receiver, which is located in a spatial region of interest served by a transmitter of a wireless communication network, receives a radio signal from at least one transmitter of the wireless communication network, and the radio signal has a plurality of position reference signal (PRS) sequences. Each PRS sequence has associated therewith a different PRS sequence identifier, and each PRS sequence is send using a different beam cone of the transmitter. The beam cones of the transmitter for sending the plurality of PRS sequences are directed to the spatial region of interest. The receiver processes the radio signal to estimate a time of arrival of each PRS sequence and to obtain for each PRS sequence the associated PRS sequence identifier. A position of the receiver is estimated using the times of arrival and the obtained PRS sequence identifiers.
