Abstract: Methods and apparatuses for scheduling and indicating scheduling information in a wireless local area network (WLAN). A station (STA) includes a transceiver configured to receive a header for a protocol data unit and a controller configured to identify common information for a plurality of STAs that are scheduled in the WLAN from a common field in the header and to identify user-specific information for the STA from a user-specific field in the header that follows the common field. An access point (AP) includes a controller configured to include common information for a plurality STAs that are scheduled in the WLAN in a common field in a header of a protocol data unit, and to include user-specific information for the STAs in a user-specific field in the header that follows the common field. The AP also includes a transceiver configured to transmit the protocol data unit including the header.

Abstract: A method, station, and access point for transmitting in a wireless local area network. A method for operating the station includes receiving a beacon signal from an access point in the wireless local area network. The method also includes identifying from the beacon signal a target transmission time of a trigger frame to be transmitted by the access point for an uplink multi-user transmission. A method for operating the access point includes transmitting, to one or more stations in the wireless local area network, a beacon signal that indicates a target transmission time of a trigger frame to be transmitted by the access point for an uplink multi-user transmission.

Abstract: 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.

Abstract: A method for operating a station (STA) in a wireless local area network (WLAN). The method comprises receiving a resource status request from an access point (AP) communicating with the STA, transmitting a resource status response including an access category (AC) information of UL data that is identified using a traffic identifier. The AC information corresponds to a set of DL queues and a set of UL queues configured at the AP to schedule the STA. The method further comprises receiving a trigger frame from the AP, wherein the trigger frame includes scheduling information of the UL data based on the AC information included in the transmitted resource status response to the AP and processing the scheduling information included in the trigger frame to transmit the UL data to the AP.
