APPARATUS, SYSTEM AND METHOD OF TRIGGER-BASED (TB) MULTI-USER (MU) UPLINK (UL) ORTHOGONAL-FREQUENCY-DIVISION-MULTIPLE-ACCESS (OFDMA) CONTROL FRAME TRANSMISSION

摘要

For example, a wireless communication device may be configured to, based on a grouping criterion, select from a plurality of STAs a group of two or more STAs for a Trigger-Based (TB) Multi-User (MU) UL OFDMA control frame transmission to be communicated from the group of two or more STAs to the wireless communication device, the grouping criterion based on two or more RSSI values corresponding to the two or more STAs, respectively; to transmit a trigger frame to trigger the TB MU UL OFDMA control frame transmission, the trigger frame including two or more STA Identifiers to identify the two or more STAs, respectively; and to process the TB MU UL OFDMA control frame transmission from the group of two or more STAs, the TB MU UL OFDMA control frame transmission including two or more control frames from the two or more STAs, respectively.
