摘要： 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.

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.

摘要： Embodiments of an access point (AP), station (STA) and method for channel access are generally described herein. The AP may contend for access to a channel. The contention may be performed in accordance with an omni-directional enhanced distributed channel access function (EDCAF) for transmission within an omni-directional pattern. The contention may be further performed in accordance with a directional EDCAF for transmission to a station (STA) in a directional pattern. The AP may determine whether to transmit within the omni-directional pattern based at least partly on an omni-directional backoff parameter. The AP may further determine whether to transmit in the directional pattern based at least partly on a directional backoff parameter.

摘要： Embodiments of a millimeter-wave communication station and method for multiple-access beamforming in a millimeter-wave network are generally described herein. In some embodiments, an initiating station performs multiple-access beamforming with one or more responding stations by announcing a number of sector-sweep (SS) slots of a beamforming training (BFT) period and a number of SS frames of each SS slot. One or more SS frames are received from one or more of the responding stations within one of the SS slots of the BFT period. The initiating station transmits one or more SS feedback frames to the responding stations within the one SS slot to indicate an antenna configuration to the responding stations for communication with the initiating station. The responding stations transmit a limited number of SS frames per SS slot based on the number of SS frames announced by the initiating station and transmit any additional SS frames in a next SS slot of the beamforming training period. Each SS frame contains an indication to the initiating station of an antenna configuration for communication with the responding station.

摘要： Methods and apparatuses enable selective operation in an extended bandwidth channel of a wireless communication band. For example, a client station can be selectively authorized to operate on a 40 MHz channel in a 2.4 GHz band. The client station or an access point or both can determine whether interference exists in the wireless communication band. If potential interference exists, the client station may operate on a non-extended bandwidth channel. If potential interference does not exist, the client station may operate on an extended bandwidth channel. Operation between the two channels can be dynamic based on continued monitoring of the wireless communication band for potential interference.
