Abstract: Methods, apparatus, and computer readable medium manage the utilization of a wireless medium capable of transmitting multiple channels of data simultaneously. A plurality of messages are stored in a queue for transmission on the wireless medium. A wireless medium utilization for transmitting a first message over the multi-channel medium is determined. Each of the messages stored in the queue is delayed based at least in part on the determined wireless medium utilization. In some embodiments, a message may be delayed based at least in part on a state of a connection used by the message. For example, if the connection is in a ramp-up or slow start phase, the message may not be delayed. Messages may also be delayed based on a type of the message. For example, messages generated by interactive applications, such as web browsers or instant messaging applications may not be delayed.

Abstract: A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.

Abstract: Techniques for proving enterprise mode security for relays are disclosed. For example, enterprise mode security based on IEEE 802.1x is provided for relays or other similar devices to extend the coverage of access point hotspots or other similar access point use cases. According to one aspect, a relay incorporates an authentication client associated with an authentication server. According to another aspect, a four address format is employed for tunneling messages via a relay between a station and an access point. According to another aspect, a cryptographic master key associated with an access point and a station is provided to a relay to enable the relay to be an authenticator for the station.
