    摘要: According to some embodiments, a technique is provided that coordinates transmission of frames to reduce collisions. Frames are coordinated according to, for example, operation type, frame length, and solicited response. A base station gains access to a wireless medium and transmits multiple coordinated frames to multiple communication units. The transmissions to the multiple communication units may be substantially simultaneous in that at least a portion of the different frames are transmitted at the same time. The different frames may be substantially back-end aligned where the maximum difference between the termination time instances of the frame transmissions is controlled to reduce collisions.

    摘要: A frame format provides for wideband wireless local area network communications and informs narrower-band communication units when the channels are occupied by wider-band communication units. In some embodiments, the frame format includes a channelization field identifying channels that are used for communicating subsequent wideband fields of a packet, and a wideband-header field communicated on the identified channels. The wideband-header field may identify sub-fields that may be present in the wideband-header field, and may identify the presence of a wideband-data field. A long-compatibility field may be present that provides protection at the MAC level. The long-compatibility field may transport MAC frames that may include medium-reservation information compatible with narrower-band communication units.

    摘要: A wireless local area network (WLAN) device transmits multiple data packets within a data burst. In various embodiments, after the first packet is transmitted, subsequent packets are transmitted before expiration of an Interframe Space (IFS). The subsequent packets may have a full-length preamble, a partial preamble or no preamble at all.

    摘要: An approach is provided for managing a probe response related to wireless medium access control. The approach involves causing, at least in part, an active scan process that includes transmitting one or more probe request messages to indicate one or more scheduling windows within which receiving one or more probe response messages is permitted in reply to the one or more probe request messages.
