Abstract
Measurement opportunities are provided to a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a CDMA wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The bursty nature of packet data transmission generates periods of inactivity or low traffic during a call. The WTRU switches to antenna beams other than the selected antenna beam for receiving and measuring signals during these periods of inactivity or low traffic. Moreover, if the network has knowledge of the fact the WTRU is operating using a switched beam antenna, the network can use this information when making decisions on channel allocations, thus providing frequent measurement opportunities to the WTRU in order to support the switched beam antenna operation.
