    • A method of sending feedback information in a fast physical layer hybrid automatic repeat request (HARQ) for frequency division duplex communications that form an overall wireless communication system is described in which the received packets are acknowledged by transmitting feedback data to the sender, wherein the acknowledgement comprises the reservation of obtaining a plurality of slots in the uplink/downlink dedicated channel radio frame for the feedback data alone. It is also directed to the transmission of feedback data used in specified slots within each radio frame, wherein the first slot used is based upon the time offset between uplink and downlink channels, as well as based upon the time required for de-interleaving, de-ratematching, decoding and error checking. In an alternative embodiment, the method uses dedicated physical control channel (DPCCH) bits in at least some of the slots for transmitting such feedback data to the sender.
    • 描述了在形成整体无线通信系统的用于频分双工通信的快速物理层混合自动重传请求(HARQ)中发送反馈信息的方法,其中通过向发送方发送反馈数据来确认所接收的分组,其中确认 包括仅在反馈数据的上行链路/下行链路专用信道无线电帧中获得多个时隙的预留。 它还针对在每个无线电帧内在指定时隙中使用的反馈数据的传输,其中所使用的第一时隙基于上行链路和下行链路信道之间的时间偏移,以及基于去交织所需的时间,de - 匹配,解码和错误检查。 在替代实施例中,该方法使用至少一些时隙中的专用物理控制信道(DPCCH)比特来将这种反馈数据发送到发送方。
