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: 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: 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 mejorado de manejo de red, particularmente en el contexto de normas IEEE802.11 y IEEE802.11k, a traves de dos nuevas medidas MAC, con ventajas acompanantes. Las dos nuevas medidas incluyen medida de carga de trafico de enlace ascendente WTRU y una medida de carga de servicio AP, y generalmente es aplicable al menos las capas 1 y 2 como se aplican en al menos 802.11K en le contexto de los sistemas OFDM y CDMA 2000, aunque tambien es aplicable a otros escenarios. Un metodo para determinar y anunciar la congestion que tambien se provee para un sistema de Red de area Local Inalambrica (WLAN). La presente invencion tambien introduce un metodo para manejar la congestion cuando se detecta la congestion. Este aspecto de la presente invencion se aplica principalmente a sistemas inalambricos que usan el mecanismo de Acceso Multiple de Percepcion Portadora/Evasion por Colision (CSMA-CA). Los metodos se implementan ventajosamente en WTRUs selectivamente configurada de varias formas.

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.
