    • A method and apparatus for measuring a channel quality in wireless transmit/receive units (WTRUs) which are equipped with a subscriber based smart antenna. The WTRUs are equipped with a smart antenna so that the WTRU generates a plurality of directional beams and, optionally, an omni-directional beam. A dwell time is provided in a measurement period to switch a beam from an active beam to a non-active beam. The active beam is one of the plurality of directional beams or, optionally, the omni-directional beam, for communication with one or more serving base station(s). A beam is switched to a non-active beam at the initiation of the dwell time. Signals are received through the switched non-active beam, and samples of the received signals are generated. The samples are stored in a memory. Channel quality is measured using the samples, whereby the dwell time to measure the channel quality is minimized.
    • 一种用于测量配备有基于用户的智能天线的无线发射/接收单元(WTRU)中的信道质量的方法和装置。 WTRU配备有智能天线,使得WTRU生成多个定向波束,并且可选地,生成全向波束。 在测量周期中提供停留时间,以将波束从有源波束切换到非有源波束。 有源波束是多个定向波束之一,或者可选地,全向波束,用于与一个或多个服务基站通信。 在停留时间开始时,光束切换到非有源光束。 通过切换的非有源波束接收信号,并且生成接收到的信号的采样。 样品存储在存储器中。 使用样本测量信道质量,从而最小化测量信道质量的驻留时间。
