Patent ID: 7123924

Claim:
A method for determining a position, speed and direction of movement of a wireless transmit/receive unit (WTRU), the method comprising: transmitting wireless communication signals from a network station in directional beams from a known location such that beams are from time to time transmitted to each area serviced by the network station, each beam including beam identifying information; a WTRU receiving a plurality of the transmitted directional beams, including beam identifying information for each of the received beams; for each of the plurality of received beams, the WTRU measuring the respective received signal strength and storing respective beam identifying information data with respective measured received signal strength data; the WTRU transmitting to the network station stored beam identifying information data and received signal strength data for the plurality of received beams; and the WTRU receiving, measuring, storing and transmitting steps being performed with respect to a selected number of no less than three directional beams successively transmitted from the network station; and estimating the position, speed and direction of movement of the WTRU using beam identifying information data and received signal strength data for the plurality of received beams received from the WTRU, the WTRU receiving, measuring, storing and transmitting steps being performed with respect to a selected number of no less than three directional beams successively transmitted from the network station.
