Abstract: A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.

Abstract: Un sistema de comunicaciones de LAN inalámbrica (WLAN) entre una pluralidad de usuarios dentro de un sistema básico de servicio o celda, que comprende: un punto de acceso de conmutación, SAP (106, 206), para transmitir y recibir comunicaciones punto-amultipunto a y desde los usuarios; y una pluralidad de terminales de usuario, cada uno de los cuales está asignado a un puerto disponible en el punto de acceso de conmutación y que definen una única combinación de una frecuencia portadora y un haz espacial para aislar comunicaciones entre usuarios para evitar colisiones; donde dicha asignación de frecuencias no es permanente, y en su lugar se hace uso de una asignación dinámica o pseudoaleatoria de portador en la cual las señales recibidas de solicitud-de-envío desde los usuarios en un portador compartido es respondida con señales de permiso de envío desde el SAP que indican el portador que puede ser utilizado para transmisión (106, 206)

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.

Abstract: A method for controlling behavior of lower layer links related to media i ndependent handover (MIH) of a mobile user comprises sending a MIH link acti ons request primitive (e.g. MIH SWITCH, MIH SCAN) from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set (a grou p, multiple, several) of lower layer links to heterogeneous radio access tec hnology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are s ent back the MIH User entity to convey the results of the execution attempts on the requested actions, IEEE 802.21 standard. (Comprising a result code).

Abstract: A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay.

Abstract: A measurement report request message (350) is sent to a measurement terminal (314) in the wireless local area network (WLAN). A measurement report response message sent from the measurement terminal is evaluated by the media access control (MAC) function (334) to determine whether a handover condition exists. A media independent handover (MIH) trigger is generated by the MAC function if the handover condition exists. The MIH trigger is sent to MIH function (340). The MIH and MAC functions are located in the same network node. Independent claims are included for the following: (1) apparatus for generating MIH trigger; and (2) communication frame for providing MIH information.

Abstract: The method involves transmitting a management frame by a mesh point (MP) to another MP, where the frame includes a medium access control (MAC) address of a destination MP. The management frame is received from the former MP, and a determination is made if it is the destination MP, by the latter MP. The management frame is updated if the latter MP determines it is not the destination MP. The management frame is transmitted to a third MP, where the management frame identifies the destination MP. Independent claims are also included for the following: (1) a mesh point (MP) in a wireless communication system, comprising a receiver (2) an integrated circuit (IC) of a mesh point.

Abstract: A method and apparatus for routing a packet implemented in a mesh point (MP) of a wireless network are described. According to the method, a plurality of intra-mesh and extra-mesh routes are compared. One of the plurality of intra-mesh and extra-mesh routes is selected for transmission of the packet based on at least one criterion. The packet is transmitted over the selected one of the plurality of intra-mesh and extra-mesh routes.

Abstract: Methods and apparatus are disclosed. A method implemented in a wireless transmit/receive unit (WTRU) includes receiving a packet from a first other WTRU during a transmission opportunity (TxOP) associated with the first other WTRU and forwarding the packet to a second other WTRU during a remaining portion of the TxOP.
