Patent ID: 7295811

Claim:
A method for operating a wireless transmit/receive unit (WTRU) in a wireless communication system comprising a plurality of cells, the WTRU comprising a switched beam antenna for generating antenna beams including a plurality of directional beams and an omni-directional beam, the method comprising: using a selected beam for exchanging data with a cell in an active set of cells; selecting a respective subset of antenna beams for each cell in the active set of cells and for each cell in a candidate set of cells; receiving signals from cells in the active set of cells and from cells in the candidate set of cells using the respective subset of antenna beams; measuring the received signals from each cell for each respective subset of antenna beams; selecting the measured signal having the highest value from each cell in the active set of cells and in the candidate set of cells; comparing the selected measured signals; and sending a measurement report to the network when the selected measured signals for a cell in the candidate set of cells exceeds a reporting threshold criteria when compared to the selected measured signals for a cell in the active set of cells.
