Abstract: A wireless communication method and apparatus for providing network advice to wireless transmit/receive units (WTRUs) are disclosed. Once start-up of a WTRU is initiated, the WTRU scans a network advice channel in a particular band, (e.g., 5.180 GHz - 5.320 GHz). If a network advice frame is detected, the WTRU tunes to a channel indicated by the network advice frame and associates with a basic service set (BSS) operating on the channel indicated by the network advice frame. Otherwise, the WTRU scans another available network advice channel in the band.

Abstract: The present invention is related to a method and system for deriving an encryption key(800) using joint randomness not shared by others(JKNSO). Communicating entities generate JRNSO bits(816) from a channel impulse response(CIR) estimate and the JRNSO bits are used in generation of an encryption key. The authentication type may be IEEE 802.1 x or a pre-shared key system. In an IEEE 802. Ix system, a master key, a pairwise master key or a pairwise transient key may be generated using the JRNSO bits. The encryption key key(828) may be generated by using a Diffie-Hellman key derivation algorithm.

Abstract: In a wireless communication system, (e.g., a wireless local area network (WLAN)), including a plurality of wireless transmit/receive units (WTRUs) and a coordinating node, (e.g., an access point (AP)), path loss is estimated by transmitting a loud packet from a first one of the WTRUs to a second one of the WTRUs. The coordinating node transmits a loud packet generation request message. A first one of the WTRUs receives the loud packet generation request message and transmits at least one loud packet at a transmission power specified by the loud packet generation request message. Optionally, the first WTRU transmits a loud packet generation response message. A second one of the WTRUs receives the loud packet and determines a path loss between the first WTRU and the second WTRU by subtracting the signal strength of the loud packet from the determined transmission power of the loud packet.

Abstract: A wireless local area network (WLAN) includes a station (706), an access point (AP 702), and a network management entity (NME 704). A method for remote radio resource management in the WLAN begins by configuring a trigger condition at the AP(702). A determination is made whether the trigger condition has been met, and a notification message is sent from the AP (702) to the NME (704) if the trigger condition has been met.

Abstract: A method for creating sub-networks in a wireless mesh network begins by determining whether a trigger condition for creating a sub-network exists. Nodes in the mesh network are selected to create the sub-network if the trigger condition exists. The sub-network is then created with the selected nodes. A node for use in a wireless mesh network includes a state device for maintaining a state of the node, the state of the node relating to activity occurring at the node; an attachment list communicating with the state device; a trigger device communicating with the state device; and an attachment device communicating with the attachment list and the trigger device
