Abstract
This disclosure describes methods, apparatus, and systems related to early indication system. A device may identify a high efficiency frame in accordance with a high efficiency communication standard, received from a first device, the high efficiency frame including, at least in part, one or more legacy signal fields and one or more high efficiency signal fields. The device may determine a length field included in one of the one or more legacy signal fields, wherein the length field includes an indication bit. The device may determine a position of a high efficiency short training field within the high efficiency frame based at least in part on the indication bit.
