Abstract: A wireless LAN (WLAN) system for communications among a plurality of users within a basic service system or cell comprising a switching access point (SAP) for transmitting and receiving point-to-multipoint communications to and from the users and a plurality of user terminals, each of which is assigned to a part available in the switching access point and defining a unique combination of a carrier frequency and a spatial beam for isolating communications among the users to prevent collisions; wherein said assignment of frequencies is not permanent and instead use is made of a dynamic or pseudo-random carrier assignment in which received request-to-send signals from the users in a shared carrier is replied to with clear to send signals from the SAP indicating the carrier that can be used for transmission.

Abstract: At a first user equipment (UE), an uplink signal of at least one second UE is received and time marked (401). At the first UE, a downlink signal from at least one base station is received and time marked (402). Observed time differences of arrival are determined using the time markings (403). A position of the first UE is determined based on the determined time differences of arrival (404).

Abstract: In a wireless communication system comprising a plurality of mesh points (MPs), a method and apparatus for transmitting management information includes a first MP transmitting a management frame to a second MP, wherein the management frame includes the medium access control (MAC) address of a destination MP. The second MP receives the management frame from the first MP and determines if it is the destination MP. The second MP updates the management frame if the second MP determines it is not the destination MP, and transmits the management frame to a third MP. The transmissions terminate when the data reaches the destination MP.

Abstract: A wireless communication system including at least one IEEE 802 multi-stack wireless transmt/receive unit (WTRU) and a plurality of technologically diversified acess networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed. Both the multi-stack WTRU and the technologically diversified networks includ a media indipendent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and atuhorization procedures based on the MIH information, obtain a local Internet Protocol (IP) address, establish a tunnel to a packet data gateway (PDG) un a 3GPP core network, constructed a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.

Abstract: A wireless LAN (WLAN) system for communications among a plurality of users within a basic service system or cell comprising a switching access point (SAP) for transmitting and receiving point-to-multipoint communications to and from the users. A plurality of ports are available at the SAP, each of which assigned to a unique carrier frequency for isolating communications among the users to prevent collisions, with the ability of frequency assignment to be non-permanent, and a capability of dynamic or pseudo-random carrier assignment. An alternative embodiment of the SAP uses beamforming to provide spatial ports for assignments to the plurality of users.

Abstract: A DEVICE FOR IDENTIFYING AN EMERGENCY CALL IN A WIRELESS LOCAL AREA NETWORK INCLUDES AN INDICATOR TO IDENTIFY A CALL AS AN EMERGENCY CALL. THE INDICATOR CAN BE A BIT FLAG OR AN INFORMATION ELEMENT. THE INFORMATION ELEMENT CAN INCLUDE LOCATION INFORMATION REGARDING THE LOCATION OF THE STATION THAT PLACED THE EMERGENCY CALL. THIS INFORMATION CAN BE USED TO LOCATED THE CALLER. THE LOCATION INFORMATION CAN BE TRANSMITTED FROM THE STATION TO AN ACCESS POINT SEPARATELY FROM AN EMERGENCY CALL.
