摘要： Embodiments of a very-high throughput communication station and method for communicating on a primary channel and up to three or more secondary channels are generally described herein. Short-preamble detection may be performed during a contention window to detect packet transmissions on any one of the secondary channels starting within the contention window. Guard-interval detection is also performed during the contention window to detect a guard interval of a packet transmission on any one of the secondary channels. The short-preamble detection and the guard-interval detection may be performed concurrently during the contention window to determine if any of the secondary channels are busy.

摘要： Embodiments may comprise logic such as hardware and/or code to mitigate or attenuate collisions of communications between wireless communications devices and access points by defining time slots for stations to communicate with the access point. Some embodiments may define time slots for stations to respond to an indication that the access point is buffering data for the station. Further embodiments may define time slots for stations to communicate with the access point whether there is data buffered for the station or not. And many embodiments may determine stations associated with communications collisions or likely to be associated with communications collisions and defines different time slots for the stations to communicate with the access point.

摘要： A System and method for creation and transport of flows. The method includes transmitting an ADDFLOW request to a receiver to add the flow to the wireless network. The method also includes receiving a response message indicating that the flow will be added to the wireless network and delivering the flow to the wireless network. A given flow may be uniquely identified by the concatenation of a flow ID and a flow address. The flow address will always be either the transmitter's or receiver's MAC address. This method could be extended to compress any bit sequences that take on only a limited set of values.

摘要： Logic may implement an orthogonal frequency division multiplexing (OFDM) system operating in the one gigahertz and lower frequency bands. Logic may detect new long training sequences that are differentially orthogonal to each other for a first bandwidth mode of operation such as a one megahertz mode as well as differentially orthogonal to half of the long training sequence for a second bandwidth mode of operation such as a two megahertz or greater mode. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. Logic may implement a new acknowledgement packet comprising a short training sequence and a long training sequence without a signal field and without a payload. And logic may implement bandwidth detection logic to classify a transmission based upon orthogonal properties of the long training sequences.
