Abstract: A METHOD AND APPARATUS FOR EFFICIENTLY PROCESSING PACKETS FROM NEIGHBORING BASIC SERVICE SETS, (BSSS) TO CHARACTERIZE THE TAFFIC WITHIN A WIRELESS LOCAL AREA NETWORK (WLAN), MESH NETWORK, OR SIMILAR WIRELESS COMMUNICATION SYSTEM IS DISCLOSED. THE APPARATUS MAY BE AN ACCESS POINT (AP) IN A BSS WHICH INCLUDES A MEASUREMENT PERIOD (MP) INTERVAL TIMER, A PROMISCUOS MEASUREMENT PERIOD (PMP) TIMER AND A RECEIVER FILTER. AN INTERVAL OF THE MP INTERVAL TIMER IS SET WHILE THE RECEIVER FILTER IS ENABLED. DURING THE INTERVAL, THE AP ONLY PROCESSES PACKETS WHICH ORIGINATED FROM THE AP'S OWN BSS. WWHEN THE MP INTREVAL TIMER EXPIRES,AVALUE OF THE PMP TIMER IS SET TO A PREDETERMINED TIME DURATION AND THE RECEIVER FILTER IS DISABLED. DURING THE PREDETERMINED TIME DURATION, THE AP PROCESSES ALL RECEIVED PACKETS IRESPECTIVE OF WHICH BSS THE PACKETS ORIGINATED FROM. THE RECEIVER FILTER IS AGAIN ENABLED WHEN THE PMP TIMEJ- EXPIRES.

Abstract: Un metodo (100) para acelerar el descubrimiento de puntos de acceso (APs) en una red inalambrica de area local comienza mediante la transmision de un paquete de anuncio por parte de un AP a traves de al menos un canal distinto del canal sobre el cual el AP transmite senales de baliza. El paquete de anuncio es recibido por una estacion (STA), que luego determina si se asocia al AP de transmision. El paquete de anuncio puede incluir informacion de re-asociacion, de forma que la STA pueda asociarse al AP en base a la informacion en el paquete de anuncio, o informacion de sincronizador, de forma que la STA pueda sintonizarse al AP y recibir la baliza del AP sin fijarse sobre el AP durante un periodo de tiempo extendido.

Abstract: Se incluye una lista de conjuntos de servicio básico (BSSs) o puntos de acceso (APs) candidatos en un mensaje de control de acceso al medio (MAC) recibido en una unidad inalámbrica de transmision/recepcion (WTRU). La lista incluye una identidad de cada BSS o AP candidato y un indicador de preferencia que indica el grado de preferencia del BSS o AP candidato para la seleccion y si el BSS o AP candidato no debe considerarse para la seleccion. La WTRU selecciona un BSS o AP utilizando la lista.

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: A wireless communication method and system for optimizing channel selection for an AP. The channel selection optimization process includes four sub-processes: (1) a measurement process; (2) a candidate channel determining process; (3) a channel selection process; and (4) a channel update process. Candidate channels used for supporting communication performed by the AP are determined. The candidate channels are chosen from an allowable channel set (ACS) if a detected interference of each candidate channel is less than an established maximum allowed interference.

Abstract: A method for use in an access point includes receiving a request for a reselection message from a wireless transmit/receive unit (WTRU). The reselection message is generated in response to the request and includes: at least one first identifier of one or more candidate basic service sets (BSSs) that may be considered for reselection; a preference indicator associated with each candidate BSS, to indicate the BSS selection preference; an expiration time indicator associated with each candidate BSS, to indicate a time period that the BSS may be considered for reselection; an indication of a measurement to be taken on a BSS and used in a target BSS reselection determination; and a margin by which the measurement must exceed a corresponding value for a currently selected BSS. The reselection message is transmitted to the WTRU. A reselection response message is received from the WTRU, indicating the target BSS reselection determination.

Abstract: Methods for sharing radio resource allocation information between access points (APs) in a wireless local area network include: sending resource allocation information from a first AP to at least one other AP; directly requesting resource allocation information from a first AP by a second AP; or requesting resource allocation information for a first AP by a second AP through a centralized entity. A similar method may also be used to allocate radio resources among APs.
