Abstract:
1. A method for operating a wireless transmit/receive unit (WTRU) in a wireless communication system comprising a plurality 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 antenna beam for exchanging data with one or more cells in an active set of cells; receiving signals from cells in an active set of cells and from cells in a candidate set of cells using the omni-directional beam; measuring the received signals from each cell for the omni-directional beam; comparing the measured signals; and sending a measurement report to the network when the measured signals for a cell in the candidate set of cells exceeds a reporting threshold criteria when compared to the measured signals for a cell in the active set of cells.
