Abstract: Methods, apparatuses, and computer readable media are shown for multi-user scheduling in wireless local-area networks (WLANs). A wireless communication device is shown including circuitry to determine a plurality of schedules for each of a plurality of channels for an orthogonal frequency division multiple access (OFDMA) communication in a wireless local-area network (WLAN). Each of the plurality of schedules may include a frequency allocation for one or more communication devices. The circuitry may be further configured to transmit the corresponding schedule of the one or more schedules on each of the one or more channels. Each of the plurality of schedules may include a schedule type and a user association identification (AID) list. A number of user AIDs in the user AID list may be based on the schedule type.

Abstract: Embodiments of a system and method for acknowledging frames in a wireless network are generally described herein. In some embodiments, a wireless communication device may include a transmit/receive unit configured to receive data from a sender. In some embodiments, the transmit/receive unit may be configured to receive a schedule. The transmit/receive unit may be further configured to acknowledge (ACK) the data in a first scheduled transmission to the sender. The first scheduled transmission to the sender may be determined based on the schedule. In some embodiments, the acknowledgement may be an acknowledgement frame or a block acknowledgment frame. The scheduled transmission to the sender may be determined based on the schedule.

Abstract: Wireless devices, methods, and computer-readable media for transmitting and receiving beacon frames are disclosed. A master station is disclosed. The master station may include circuitry configured to operate in accordance with orthogonal frequency division multiple access (OFDMA) on a plurality of sub-channels and a primary channel. The circuitry may be further configured to assign a high-efficiency wireless local-area network (HEW) station to a sub-channel and transmit a legacy beacon on the primary channel with a first period. The circuitry may be further configured to transmit a HEW beacon on the sub-channel with a second period, wherein the second period is greater than the first period. The circuitry may be further configured to determine that the HEW station has data at the master station, and to transmit the HEW beacon on the sub-channel with an indication that the HEW station has the data. A HEW station is disclosed for receiving HEW beacons.

Abstract: Embodiments of a system and method for communicating acknowledgments in a wireless network are generally described herein. In some embodiments, a method of wirelessly communicating acknowledgements includes receiving a first signal on a first subchannel from a second wireless device. The method may include transmitting a block acknowledgement of the first signal on a subchannel. The first wireless communication device may not receive a block acknowledgement request to transmit the block acknowledgement. In some embodiments, a method of communicating block acknowledgements includes transmitting a first transmission to a first wireless device on a first subchannel and a second transmission to a second wireless device on a second subchannel. The method may include receiving a first block acknowledgement from the first wireless device and a second block acknowledgement from second wireless device. The first and second block acknowledgement may be received on one of the first and second subchannels.

Abstract: Embodiments of master station and method for high-efficiency WLAN (HEW) communication are generally described herein. In some embodiments, the master station is configured for HEW communication in accordance with an IEEE 802.11ax technique. The master station may transmit an indication to one or more of a plurality of HEW stations to indicate which one of a plurality of 20 MHz channels to monitor for a HEW signal field. The master station may configure the HEW signal field to indicate which of a plurality of subchannels of the indicated 20 MHz channel is allocated to the HEW stations for communication. The master station may transmit the configured HEW signal field in the indicated one of the 20 MHz channels and may communicate with the HEW stations on the indicated subchannels in accordance with an orthogonal-frequency divisional multiple access (OFDMA) technique.
