摘要： 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.
