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 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 method and system for improving interoperability of a radio network controller and a base station in cellular systems with downlink congestion control is disclosed. A message is sent from a base station to a radio network controller after the base station has discarded at least one transport block. The message sent to the radio network controller may be forwarded by the radio network controller to additional radio network controllers serving users affected by the discard of the at least one transport block.

Abstract: A method for changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.

Abstract: During a contention-free period, or silent measurement period, of a first wireless communications channel, signals received on a second wireless communications channel are analyzed. The results of the analysis are used to perform advanced radio resource management functions, such as frequency selection, load balancing, or power management. Each of a plurality of wireless channels may be measured in order to perform the advanced radio resource management functions. During the analysis, an energy detect threshold may be lowered to a minimal value.

Abstract: A method for accelerating discovery of access points (APs) in a wireless local area network begins by transmitting an advertisement packet by an AP via at least one channel other than a channel on which the AP transmits beacon signals. The advertisement packet is received by a station (STA), which then determines whether to associate to the transmitting AP. The advertisement packet can include reassociation information, such that the STA can associate to the AP based on the information in the advertisement packet, or timing information, such that the STA can tune to the AP and receive the AP's beacon without dwelling on the AP for an extended period of time.
