Claim 15:
16. A method for receiving a frame by a wireless device, the method comprising:
receiving, using a receiver of the wireless device, a plurality of Resource Units (RUs) of the frame;
extracting, by the wireless device, a first plurality of pilots from one or more RUs of the plurality RU at a first set of positions, respectively; and
processing, by the wireless device, the frame using the first plurality of pilots,
wherein the frame is an Orthogonal Frequency Division Multiple Access (OFDMA) frame and the plurality of RUs include respective pluralities of subcarriers,
wherein the first set of positions are uniformly spaced,
wherein a first RU is a 26-subcarrier RU and a second RU of the frame is a 52-subcarrier RU,
wherein the first set of positions correspond to non-null positions of a Long Training field (LTF) of the frame, and
wherein when the frame includes a 4× High Efficiency (HE) Long Training Field (HE-LTF), the first RU carries two pilots, and the second RU carries four pilots.
