Abstract: Apparatuses and methods for separately scheduling and grouping multiple wireless local area network (WLAN) users are disclosed. The apparatuses and methods include scheduling, at an access point (AP), multiple wireless stations (STAs) associated with the AP; identifying based at least in part on the ranking, a group of STAs from the STAs for transmission of data over a single orthogonal frequency-division multiple access (OFDMA) frame in a WLAN; and providing information resulting from scheduling the STAs and identifying the group of STAs to at least one of the STAs. In others aspects, the apparatuses and methods include receiving at an STA from an AP, scheduling information for a group of STAs including the STA; and transmitting based on the scheduling information, data over an OFDMA frame in an unlicensed or shared spectrum, the STA having a traffic load different from the traffic load of the at least one additional STA.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to receive information indicating a wake time period from a STA and use the received wake time period to schedule communication with the STA. The apparatus may use the received wake time period to determine a target transmission time for transmitting a trigger frame to the STA. The apparatus may transmit a beacon to the STA and then transmit the trigger frame to the STA at the target transmission time following the beacon. The apparatus may also indicate an offset from the beacon that the apparatus will use for communication with the STA based on the wake time period of the STA.
