Abstract
Methods and apparatuses for Subchannel Selective Transmission (SST) in a Wireless Local Area Network (WLAN) are provided herein. A station (STA) may receive a trigger frame from an access point (AP). The trigger frame may indicate a range of association identifiers (AIDs) and/or subchannel information. The subchannel information may identify one or more secondary subchannels for an SST. The STA may determine that the AID of the STA is within the range of AIDs indicted in the trigger frame. The STA may send feedback to the AP that indicates that the STA will monitor one or more of the secondary subchannels. The STA may receive the SST from the AP on a secondary subchannel of the one or more secondary subchannels. The STA may send an acknowledgment (ACK) to the AP on the secondary subchannel in response to receipt of the SST.
