摘要
A method for operating an access point (AP) in a wireless local area network (WLAN). The method comprises identifying a bandwidth of an orthogonal frequency division multiple access physical protocol data unit (OFDMA PPDU) by at least one of a primary channel or at least one secondary channel, and nulling a plurality of tones of OFDMA PPDU for the at least one secondary channel sensed busy. The method further comprises transmitting, to a station (STA), a bandwidth signaling sub-field in high efficiency signal-A (HE-SIG-A) field included in a high efficiency multi-user PPDU (HE MU PPDU) indicating availability of at least one content channel, wherein the at least one content channel of high efficiency signal-B (HE-SIG-B) field on the downlink signal including a primary channel and one or more secondary channels that comprise a plurality of OFDMA PPDUs.
