Abstract:
Embodiments of the present invention provide several long training sequences that are in a wireless local area network and that comply with 802.11ax.

Claim (Index 4):
A method for receiving a data packet in a wireless local area network, comprising:\n receiving, by a receiving end, the receiving end is a station or an access point (AP), a data packet that complies with the 802.11lax standard ( 201 , 401 ); obtaining, by the receiving end, according to a transmission bandwidth, a high efficiency long training field (HE-LTF) sequence corresponding to the transmission bandwidth ( 202 , 401 ); and determining, by the receiving end, according to a size and a location of a resource block RU allocated to a station, in the data packet, a corresponding HE-LTF sequence segment as a reference sequence that corresponds to the RU for channel estimation ( 203 ,  402 ); wherein a 2\u00d7 HE-LTF sequence in an 80 MHz bandwidth transmission substantially corresponds to: HE-LTF 2x (\u2212500:2:500)=[+1, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, +1, +1, +1, \u22121, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, +1, +1, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, \u22121, +1, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, +1, +1, 0, 0, 0, +1, \u22121, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, +1, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, \u22121, +1, \u22121, \u22121, +1, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, \u22121, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, +1, \u22121, \u22121, +1, +1, +1, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, +1, +1, +1, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, \u22121, +1, +1, \u22121, +1, +1, \u22121, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, \u22121, \u22121, \u22121, +1, \u22121, \u22121, +1, \u22121, +1, +1, +1, \u22121, +1, +1, +1, +1, \u22121, \u22121, \u22121, \u22121, +1, +1, +1, \u22121, +1, +1, \u22121, \u22121, +1, \u22121, \u22121, \u22121, +1, +1, +1, +1, \u22121, +1, +1, +1, \u22121, +1, +1], wherein the 2\u00d7 HE-LTF sequence in the 80 MHz bandwidth transmission includes values on subcarriers with even indexes in indexes \u2212500\u02dc500, the values on subcarriers with other locations are 0.
