Abstract: WIRELESS COMMUNICATION METHODS AND COMPONENTS THAT IMPLEMENT HANDOFF IN WIRELESS LOCAL AREA NETWORKS THIS INVENTION RELATES TO WIRELESS LOCAL AREA NETWORKS, AND 5 PARTICULARLY TO THE IEEE 802.11 FAMILY OF STANDARDS. IT CONSISTS OF A METHOD I AND APPARATUS THAT CAN BE IMPLEMENTED IN ACCESS POINTS (APS) AND SUBSCRIBER WIRELESS TRANSMIT/RECEIVE UNITS (WTRUS), IN ORDER TO ALLOW IN AP TO INITIATE RE-ASSOCIATION OF A WTRU TO ITSELF OR A DIFFERENT AP. THE INVENTION IMPROVES THE ROBUSTNESS OF THE NETWORK BY ENABLING MORE EFFICIENT LOAD 10 BALANCING, CONGESTION CONTROL, AND ROAMING, WITHOUT COMPROMISING THE USER EXPERIENCE. FIG,URE 3

Abstract: An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to at least 802.11k in the context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect for the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision advantageously implemented in selectively configured WTRUs of various forms.

Abstract: A method for neighbor scanning in a wireless local area network having a station, a first access point, AP, to which the station is associated, and a second AP, comprising the steps of generating timing information regarding a beacon signal sent by the second AP, reporting the timing information from the first AP to the station and scheduling at the station a time, based on the timing information, to listen for the beacon signal transmitted by the second AP. The timing information includes an indication of a time difference between a second beacon signal sent by the access point and the first beacon signal sent by the second AP and the time difference is an offset in timing units.

Abstract: Un metodo para comunicar una lista de candidatos para transferencia en una red de area local inalambrica desde una estacion a un punto de acceso de servicio (AP) empieza con la determinacion de una lista de AP candidatos para transferencia en la estacion. La lista de candidatos, se selecciona en la estacion y se envia al AP servidor. El paso de envio puede incluir el envio de la lista de candidatos al AP servidor al terminar un periodo predeterminado o al recibirse en la estacion un accionador de evento. El metodo tambien puede incluir el paso de solicitar al AP servidor una lista de candidatos de la estacion.

Abstract: Un método para escaneado de vecinos en una red inalámbrica de área local con una estacion, un primer punto de acceso (AP) con el que está asociada la estacion, y un segundo AP, comienza por medio de la generacion de informacion de timing relacionada con una senal de baliza enviada por el segundo AP. La informacion de timing es informada del primer AP a la estacion. La estacion programa un tiempo, en base a la informacion de timing, para escuchar la senal de baliza transmitida por el segundo AP.
