摘要:
Wireless devices, methods, and computer-readable media for transmitting and receiving high-efficiency signal fields. An access point (AP) may include circuitry configured to determine a high-efficiency signal (HE-SIG) field for each of a plurality of sub-channels, wherein each HE-SIG field includes a common part and a sub-channel specific part. The circuitry may be further configured to transmit, in accordance with orthogonal frequency division multiple access (OFDMA), on each of the plurality of sub-channels, a corresponding HE-SIG field as a preamble to a physical layer convergence protocol (PLCP) protocol data unit (PPDU), wherein the sub-channel specific part of the corresponding HE-SIG field includes a resource map field that enables a HEW device to determine which portion of the PPDU to demodulate, and wherein the common portion includes information of a format of the PPDU. A HEW device may include circuitry configured to demodulate a PPDU based on a HE-SIG field.
