Abstract: Un método para descubrir puntos de acceso (APs) 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, método que comprende: recibir un pedido de informacion de temporizacion desde la estacion; recibir informacion de temporizacion en el primer AP para una senal de bauza enviada por el segundo AP; informar la informacion de temporizacion a la estacion, en donde la informacion de temporizacion incluye una referencia de tiempo absoluta para transmision de la senal de baliza; y programar un tiempo en el cual la estacion puede escuchar la senal de baliza transmitida por el segundo AP, estando la programacion basada en la informacion de temporizacion. También se divulgan estaciones y puntos de acceso que emplean al método.

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 I and 2 as applied to a 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 of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms. (Fig. 3)

Abstract: This invention relates to wireless local area networks, and particularly to the IEEE 802.11 family of standards. It consists of a method and apparatus that can be implemented in access points (APs) and subscriber wireless transmit/receive units (WTRUs), in order to allow an 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 balancing, congestion control, and roaming, without compromising the user experience.

Abstract: Un método para el modelado de un sistema radioeléctrico de comunicaciones de acceso múltiple por división de código, cuyo método comprende: proporcionar (24) una pluralidad de instantáneas en el tiempo, en donde cada instantánea tiene una pluralidad de equipos de usuario (UE, 22), y estaciones base (20), variando las posiciones de los UE en cada instantánea en el tiempo entre las mismas; para cada instantánea: asignación (26) de los UE a las estaciones base; asignar secuencialmente (28) cada uno de los recursos de los UE y después de la asignación secuencial a los UE, determinando (30) un nivel de la potencia de transmisión del UE; para cada asignación secuencial, determinar (30) un nivel de potencia de transmisión para cualquiera de los UE (equipo de usuario) a los que previamente se les haya asignado recursos; determinar (32) un numero de UE retirados y UE no admitidos que hubieran tenido la asignación de recursos en la instantánea en el tiempo; y concentrar (34) las estadísticas del rendimiento del sistema utilizando el numero determinado de los UE retirados y UE no admitidos de la pluralidad de UE.

Abstract: A model for a wireless code division multiple access communication system is generated. A plurality of first snapshots is provided. Each first snapshot has a plurality of user equipments (UEs) and base stations. Locations of the UEs in each first snapshot vary between the first snapshots. For each first snapshot, that first snapshot is divided into an uplink and downlink snapshot. For the uplink snapshot, uplink resources are assigned to each UE and an uplink transmission power level is determined of that UE. Dropped and not admitted UEs are determined in the uplink snapshot. For the downlink snapshot, downlink resources are assigned to each UE. Dropped and not admitted UEs are determined in the downlink snapshot based on the assigned downlink resources. Statistics are gathered on a performance of the system using the determined dropped and not admitted UEs.

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.
