Claim 8:
9. A method comprising:
determining, by a station, a number of symbols utilized for a long training field (LTF) based on a number of space-time streams associated with a wireless local area network (WLAN) communication, wherein the number of symbols utilized for the LTF comprises 1, 2, 4, 6, or 8 symbols, wherein, on condition that the number of space-time streams is equal to 3, 5, or 7, the number of symbols is a next higher number than the number of space-time streams; and
transmitting, by the station, in an uplink multiple input multiple output (UL transmission, the determined number of symbols utilized for the HE LTF using a set of subcarriers associated with a subchannel including subcarrier indices, wherein the subcarrier indices are associated with the number of space-time streams.
