Abstract:
1. A method for performing measurements by a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a CDMA wireless communication system comprising a plurality of cells, the switched beam antenna for generating antenna beams including a plurality of directional beams and an omni beam, the method comprising: operating in an active state for exchanging data with at least one cell using a selected antenna beam; waiting to be placed in a control hold state; maintaining an assigned dedicated control channel with the at least one cell using the selected antenna beam when placed in the control hold state; switching to antenna beams other than the selected antenna beam for receiving signals from the at least one cell when the dedicated control channel is assigned; measuring the received signals from the at least one cell for each switched antenna beam; and the switching and measuring being performed when a reverse pilot channel is gated off.
