    • A method and apparatus for controlling transmission of a channel quality indicator (CQI) in a wireless communication system are disclosed. A wireless transmit/receive unit (WTRU) determines, at each transmission time interval (TTI), whether a CQI timer has expired. The CQI timer is reset each time a CQI is sent out by the WTRU. If the CQI timer has expired, the WTRU determines whether a CQI reporting opportunity exists in a current TTI. The WTRU sends a CQI if a CQI reporting opportunity exists in the current TTI. Otherwise, the WTRU waits for a next TTI. The CQI reporting opportunity exists when there is uplink data to be transmitted in the current TTI, when the WTRU needs to send a positive acknowledgement (ACK) or a negative acknowledgement (NACK) in the current TTI, or when a dedicated physical control channel (DPCCH) burst is scheduled to be transmitted in the current TTI.
    • 公开了一种用于控制无线通信系统中的信道质量指示符(CQI)的传输的方法和装置。 无线发射/接收单元(WTRU)在每个传输时间间隔(TTI)下确定CQI定时器是否已经过期。 每当CQI由WTRU发出时,CQI定时器被复位。 如果CQI定时器已经到期,则WTRU确定在当前TTI中是否存在CQI报告机会。 如果CQI报告机会存在于当前TTI中,则WTRU发送CQI。 否则,WTRU等待下一个TTI。 当WTRU需要在当前TTI中发送肯定确认(ACK)或否定确认(NACK)时,或当专用物理控制信道(...)的情况下,当存在要在当前TTI中发送的上行链路数据时存在CQI报告机会 DPCCH)突发被调度为在当前TTI中发送。

    • Components and method are provided to efficiently process wireless communications data where prior knowledge of a specific format of the communication data is not available. A wireless transmit receive unit (WTRU) is configured for use in a wireless communication system where communication data for selected channels is transmitted in system time frames in formats selected from among a set of predefined formats. The WTRU has a receiver, a memory, a received chip rate processor (RCRP) and a format detector. The RCRP is preferably configured to despread each wireless signal of spread data received in each time frame using a minimum spreading code or other appropriate key sequence and to store resultant despread data for each respective time frame in the memory. The format detector is preferably configured to determine the number of physical channels and the respective spreading factor for each physical channel for the wireless signal of spread data.
    • 提供组件和方法以有效地处理无线通信数据,其中通信数据的特定格式的先前知识不可用。 无线发射接收单元(WTRU)被配置为在无线通信系统中使用,其中所选信道的通信数据以系统时间帧的形式从一组预定格式中选出。 WTRU具有接收机,存储器,接收的码片速率处理器(RCRP)和格式检测器。 优选地,RCRP被配置为使用最小扩展码或其他适当的密钥序列来解扩每个时间帧中接收的扩展数据的每个无线信号,并且将每个相应时间帧的合成解扩数据存储在存储器中。 格式检测器优选地被配置为确定用于扩展数据的无线信号的每个物理信道的物理信道的数量和相应的扩展因子。
