This disclosure describes methods, apparatus, and systems related to a high efficiency signal field encoding structure. A device may determine a communications channel having a bandwidth of a frequency band. The device may determine a first group of subchannels of the bandwidth and a second group of subchannels of the bandwidth. The device may determine a high efficiency signal field to be transmitted on the communications channel to a first device. The device may encode the high efficiency signal field using the first group of subchannels and the second group of subchannels. The device may cause to send the high efficiency signal field to the first device.
