Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

Abstract: Computer readable media, methods, and apparatuses for centralized channel access for primary and secondary channels are disclosed. An apparatus is disclosed comprising memory and processing circuitry. The processing circuitry is configured to encode a schedule of one or more resource allocations, wherein each resource allocation comprises a type of allocation, a bandwidth, an indication of a channel, a source association identification (AID), a destination AID, an allocation start, and a duration. The type of allocation may be a service period (SP) or a contention-based access period (CBAP). The channel may be an indication of a basic service set (BSS) or a personal BSS (PBSS) primary channel, BSS or PBSS secondary channel, or BSS or PBSS tertiary channel. The processing circuitry may be configured to transmit the schedule to one or more stations identified by the source AID and the destination AID of the one or more resource allocations.

Abstract: Some embodiments relate to methods, computer readable media, and apparatus for resolving acknowledgements between associated and unassociated stations. An apparatus is disclosed including processing circuitry configured to decode responses to a random-access trigger frame, wherein one of the responses is a response from an unassociated station. The processing circuitry may be further configured to: encode an acknowledgement to acknowledge receipt of the response from the unassociated station, where the acknowledgement comprises an indication that the acknowledgement is for the unassociated station, and where the acknowledgement further comprises a media access control (MAC) address of the unassociated station in a field of the acknowledgement other than a field in a MAC header portion of the acknowledgement. The processing circuitry may configure the HE access point to transmit the acknowledgement.

Abstract: Embodiments of an access point (AP) may comprise memory and processing circuitry coupled to the memory, and transceiver circuitry coupled to the processing circuitry. The processing circuitry of the AP may be configured to generate a trigger frame to allocate a center 26 tone RU for an HE-trigger-based PPDU, the center 26 tone RU having an adjacent upper 20 MHz subchannel and an adjacent lower 20 MHz subchannel. In an embodiment, the center 26 tone RU is for a station (STA) and wherein the trigger frame indicates to the STA to transmit a pre-HE-STF preamble on one of the adjacent upper 20 MHz subchannel, the adjacent lower 20 MHz subchannel, or both the adjacent upper and lower 20 MHz subchannels, and configure the wireless device to transmit the trigger frame to the station.

Abstract: New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.
