    • 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。

    • A method for transmitting a subchannel availability for an uplink (UL) multi-user (MU) transmission is described. An availability of one or more subchannels of an orthogonal frequency division multiplex (OFDM) channel are determined by a first communication device for the UL MU transmission. A High Throughput (HT) Control field of a media access control (MAC) header that includes an indication of the determined availability of the one or more subchannels is generated by the first communication device. A MAC protocol data unit (MPDU) that includes the HT Control field is generated by the first communication device. The MPDU is transmitted by the first communication device to a second communication device via the OFDM channel for a subsequent allocation of radio resources for the UL MU transmission by the second communication device.
    • 描述了用于发送上行链路(UL)多用户(MU)传输的子信道可用性的方法。 正交频分复用(OFDM)信道的一个或多个子信道的可用性由用于UL MU传输的第一通信设备确定。 包括所确定的一个或多个子信道的可用性的指示的媒体访问控制(MAC)报头的高吞吐量(HT)控制字段由第一通信设备生成。 包括HT控制字段的MAC协议数据单元(MPDU)由第一通信设备生成。 MPDU由第一通信设备经由OFDM信道发送给第二通信设备,用于第二通信设备用于UL MU传输的无线电资源的后续分配。
