Patent ID: 7079843

Claim:
In a wireless communication system including a plurality of cells and at least one wireless transmit/receive unit (WTRU) having at least one beam antenna which is configured to transition between a switch beam mode and an omni-directional beam mode, a method comprising: (a) the WTRU communicating with a serving cell while the beam antenna is in the switch beam mode; (b) the WTRU performing at least one measurement on signals received from cells neighboring the serving cell to determine measurement results associated with the cells; (c) the WTRU determining whether each of the measurement results exceeds at least one predetermined threshold; (d) establishing a set of cells associated with the measurement results that exceed the at least one predetermined threshold; and (e) if the WTRU determines that the number of cells in the set reaches a predetermined number set by an operator of the system, transitioning the beam antenna in the WTRU from the switch beam mode to the omni-directional beam mode.
