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 1 and 2 as applied to at 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 for the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision advantageously implemented in selectively configured WTRUs of various forms.

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: Un método para escaneado de 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, comienza por medio de la generacion de informacion de timing relacionada con una senal de baliza enviada por el segundo AP. La informacion de timing es informada del primer AP a la estacion. La estacion programa un tiempo, en base a la informacion de timing, para escuchar la senal de baliza transmitida por el segundo AP.

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 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.

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 for the present invention applies primarily to wireless systems that use the 15 Carrier Sense Multiple Access/ Collision advantageously implemented in selectively configured WTRUs of various forms.
