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 begins by generating timing information regarding a beacon signal sent by the second AP. The timing information is reported from the first AP to the station. The station schedules a time, based on the timing information, to listen for the beacon signal transmitted by the second AP.

Abstract: Se revelan unidades de transmision y recepcion inalámbricas (WTRUs) que reciben una transmision de enlace descendente de un nodo B y decodifican la transmision de enlace descendente. Si no tiene éxito la decodificacion, la WTRU envía una ráfaga de senales predefinida indicando un aviso de recepcion negativa (NACK) al Nodo B por un canal de retroalimentacion compartido en situacion de contencion. La ráfaga de senales predefinida puede enviarse unicamente una vez sin necesidad de confirmacion de recepcion. El nodo B calibra la energía de transmision de enlace descendente de modo que la transmision de enlace descendente es transmitida con alta probabilidad de recepcion a las WTRUs. El nodo B puede enviar la transmision de enlace descendente, incluyendo varias corrientes de datos procesadas utilizando esquemas de codificacion y modulacion diferentes de modo que la WTRU que tenga una calidad de senal alta decodifique todas las corrientes de datos, asimismo la WTRU que tenga calidad de senal baja no decodifica todas las corrientes de datos. El nodo B envía un umbral de indicador de calidad de canal (CQI) de modo que cada WTRU determine una corriente de datos para enviar la retroalimentacion en funcion del umbral de CQI y el CQI medido.

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 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 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.
