Abstract: Se divulgan un método y sistema para proveer acceso remoto inteligente a unidades inalámbricas de transmisión/recepción (WTRUs). Un traductor es provisto en estaciones base de forma que los controladores de sistema pueden emitir mensajes de protocolo de gestión de red de nivel de aplicación a estaciones base. Los mensajes son transmitidos por el traductor a un protocolo de mensaje de control de acceso al medio (MAC) y reenviados a WTRUs. La información provista por WTRUs a estaciones base es traducida de un protocolo MAC a un protocolo de gestión de red de nivel de aplicación de forma que puede accederse a la información por medio de controladores de sistema utilizando protocolos de gestión de red de nivel de aplicación.

Abstract: The present invention integrates resource allocation between time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems. A radio network controller (RNC) receives a radio access bearer (RAB) request from a core network or a wireless receive/transmit unit. The RNC utilizes a TDD-FDD selector to assign radio resources in response to the request. The TDD-FDD selector evaluates various parameters regarding the received RAB request and determines whether it is preferable to assign TDD resources or FDD resources and whether such resources are currently available. Once resources are assigned, system conditions are evaluated to determine whether optimizations may be made to a current resource allocation.

Abstract: Method and apparatus employed by wireless network components such as access points (APs) for controlling transmitting power level of individual wireless transmitter/receiver units (WTRUs) by establishing a power transmit level based on prior transmit and receiving transmission and reception statistics such as signal to noise ratio (SNR), bit error rate (BER), frame error rate (FER) and/or the like. Power transmit level information is preferably communicated through any one of a clear to send (CTS), request to send (RTS), data and acknowledge (ACK) frame. Alternatively the power control information may be inserted into a beacon frame or an individual control frame specifically designated for power control. The WTRUs preferably have battery level sensors and adjust power control level responsive to a sensed battery level. Alternatively, the APs and WTRUs may reverse roles and the WTRUs may provide power transmit level information to an AP to facilitate transmissions by the AP.

Abstract: A method and system is disclosed for providing assistance data to wireless transmit/receive units (WTRUs). The assistance data includes information regarding the access point's neighboring access points. The assistance data is transmitted to WTRUs using multicast and/or broadcast type signaling and facilitates ring and handover of WTRUs from one access point to another.

Abstract: A wireless LAN (WLAN) system for communications among a plurality of users (101-105) within a basic service system or cell comprising a switching acces s point (SAP) (106) for transmitting (116) and receiving (118) 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 f or 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 th e SAP uses beamforming to provide spatial ports for assignments to the plurali ty of users.

Abstract: Methods and apparatus for a radio access network Internet Protocol (RAN IP) gateway. The methods include receiving data in a third generation partnership project (3GPP) wireless format from at least one user equipment (UE). The methods include transmitting the data in internet protocol, IP, formatted packets for routing so as to bypass a core network. The methods further include transmitting authentication, authorization, and accounting, AAA, information related to the at least one UE to the core network using a tunnel.
