    • A method of transmitting at least one data stream using superposition coding (SPC) in a wireless communication system is disclosed. More specifically, a method includes receiving feedback information from at least two access terminals (ATs), assigning the at least two ATs as a first AT or a second AT based on the feedback information, wherein the first AT has a smaller path loss than that of the second AT, and the second AT has a larger path loss than that of the first AT, channel coding the at least one inputted data stream by a channel coding scheme, modulating the at least one data stream using layered modulation scheme, allocating wireless resources to symbols of the first AT and the second AT, and transmitting the symbols to at least one of the first AT and the second AT according to the allocated wireless resources.
    • 公开了一种在无线通信系统中使用重叠编码(SPC)发送至少一个数据流的方法。 更具体地说,一种方法包括从至少两个接入终端(AT)接收反馈信息,基于反馈信息将至少两个AT分配为第一AT或第二AT,其中第一AT具有比那个更小的路径损耗 并且第二AT具有比第一AT更大的路径损耗,通过信道编码方案对至少一个输入数据流进行信道编码,使用分层调制方案调制至少一个数据流,分配无线 资源到第一AT和第二AT的符号,并且根据分配的无线资源将符号发送到第一AT和第二AT中的至少一个。

    • A method for providing an assignment acknowledgement includes receiving a forward link overhead channel message at an access terminal (AT), the overhead channel message including parameters used to indicate which shared control channel (SCCH) message data blocks are to be acknowledged by the AT and the timing for transmitting the assignment acknowledgment. The method further includes receiving a forward link SCCH signal having SCCH data blocks, decoding the SCCH data blocks according to parameters provided by the overhead channel message, detecting a change in access terminal assignment for the AT based upon the SCCH signal, and receiving forward link packet data, or transmitting reverse link data packet at the AT via the assigned data channel. Additional operations include identifying an offset which defines that a certain number of subpackets of the packet data have been transmitted before an assignment acknowledgement is to be transmitted, and transmitting the assignment acknowledgement according to the offset to indicate successful decoding of one of the SCCH data blocks only if the packet data has not been acknowledged
    • 一种用于提供分配确认的方法,包括在接入终端(AT)处接收前向链路开销信道消息,所述开销信道消息包括用于指示哪个共享控制信道(SCCH)消息数据块要被AT确认的参数,以及 发送分配确认的时间。 该方法还包括接收具有SCCH数据块的前向链路SCCH信号,根据由开销信道消息提供的参数对SCCH数据块进行解码,基于SCCH信号检测AT的接入终端分配变化,以及接收前向链路 分组数据或经由分配的数据信道在AT发送反向链路数据分组。 附加操作包括识别限定在要发送分配确认之前已经发送了分组数据的一定数量的子分组的偏移量,并且根据偏移量发送分配确认以指示SCCH数据块之一的成功解码 只有分组数据尚未被确认
