摘要： Apparatuses, methods, and computer readable media are disclosed for fragmentation of media access control service data units (MSDU) in a high-efficiency wireless local-area network. An apparatus of a access point or station comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry is configured to fragment a media access control (MAC) service data unit (MSDU) into two or more MSDU fragments, and encapsulate the two or more MSDU fragments into two or more aggregated MSDUs (A-MSDUs); one or more A-MSDUs and one or more MAC protocol data units (MPDUs); or, two or more MPDUs. The processing circuitry may be further configured to encode a delimiter in front of a first fragment of the two or more MSDU fragments, where the delimiter indicates a length of the two or more MSDU fragments, and to encode each MPDU to comprise a sequence number.

摘要： Embodiments of a virtual access point (VAP) and method for channel selection in a wireless network are generally described herein. The VAP may determine, from a group of channels available for VAP usage, a primary channel for the VAP based at least partly on a determination of whether the channels of the group are used as primary channels by one or more other VAPs. The VAP may transmit a downlink signal to a station (STA) in VAP channel resources that include the determined primary channel and one or more secondary channels. The VAP may use a first encryption type and a first media access control (MAC) identifier while a second VAP may use a second encryption type and a second media access control (MAC) identifier. In some embodiments, multiple VAPs may be supported by a single access point (AP).
