Abstract
Embodiments of a transmission signaling structure for HEW are defined to carry packet information to configure OFDMA receivers for demodulation of a specific portion of the packet and/or to configure receivers for transmission using specific OFDMA and MU-MIMO resources. In some embodiments, the specific portion of the packet comprises one or more minimum bandwidth units of one or more 20 MHz channels. Each 20 MHz bandwidth structure may comprise several minimum bandwidth units to allow each 20 MHz channel to have a have smaller granularity than 20 MHz.
