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: 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: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi Gigabit (EDMG) support indication. For example, a wireless station may be configured to generate a frame having a structure compatible with a Directional Multi Gigabit (DMG) frame structure, the frame including an EDMG supported field to indicate that the wireless station supports one or more EDMG features; and to transmit the frame over a DMG channel.
