Abstract
Measurements for handoff are made by a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The WTRU measures signals from a plurality of cells with the omni-directional beam and/or one or more of the directional beams. The WTRU evaluates and reports to the network measurement of the omni-directional beam or the strongest beam for adding cells to an active set of cells. For removing cells from an active set of cells, the WTRU evaluates and reports to the network measurements of the antenna beam selected for communication with the active set cells.
