    • A communication device maps a plurality of bits to a first set of transmission symbols corresponding to a first set of subcarriers within a component communication channel. Transmission symbols among the first set of transmission symbols correspond to respective subsets of one or more bits, and transmission symbols among the first set of transmission symbols are single carrier transmission symbols. The communication device maps the plurality of bits to a second set of transmission symbols corresponding to a second set of subcarriers within the component communication channel. At least a subset of multiple transmission symbols in the second set of transmission symbols correspond to phase adjusted versions of transmission symbols in a corresponding at least a subset of multiple transmission symbols in the first set of transmission symbols. The communication device generates a transmission signal using the first set of transmission symbols and the second set of transmission symbols.
    • 通信设备将多个比特映射到对应于分量通信信道内的第一组子载波的第一组传输符号。 第一组传输符号中的传输符号对应于一个或多个比特的各个子集,并且第一组传输符号中的传输符号是单载波传输符号。 通信设备将多个比特映射到对应于分量通信信道内的第二子载波集合的第二组传输符号。 第二组传输符号中的多个传输符号的至少一个子集对应于第一组传输符号中的多个传输符号的对应至少一个子集中的传输符号的相位调整版本。 通信设备使用第一组传输符号和第二组传输符号来产生传输信号。

    • Techniques are provided for transmitting and receiving a mother code in an incremental redundancy hybrid automatic repeat request protocol. A set of information bits corresponding to a message may be encoded and interleaved to produce the mother code. Each bit position of the mother code may be mapped to an output symbol, and each output symbol may be mapped to an antenna for transmission. One or more transmissions of symbols contained in the output symbols may be performed, where each transmission may include puncturing the mother code by selecting one or more symbols from the of output symbols, and transmitting each symbol in the one or more symbols on an antenna corresponding to that symbol. The mother code may be decoded, in part, by determining combinable bits contained within a set of received symbols, and computing one or more log likelihood ratio values corresponding to each symbol in the set of received symbols.
    • 提供了用于以增量冗余混合自动重复请求协议发送和接收母码的技术。 对应于消息的一组信息位可以被编码和交织以产生母码。 母码的每个比特位置可以被映射到输出符号,并且每个输出符号可以被映射到天线以进行传输。 可以执行输出符号中包含的符号的一个或多个传输,其中每个传输可以包括通过从输出符号中选择一个或多个符号来对母码进行穿刺,并且在天线上的一个或多个符号中发送每个符号 到那个符号。 可以部分地通过确定包含在一组接收符号内的可组合比特,以及计算与所接收符号集合中的每个符号相对应的一个或多个对数似然比值来对母码进行解码。
