Abstract
A method and apparatus may be used for network management via MAC measurements. The measurements may include WTRU uplink traffic loading measurement, and an AP service loading measurement. The measurements may be applicable to at least to layers 1 and 2 as applied to, for example, 802.11k in the context of OFDM and CDMA 2000 systems, but may be applicable to other scenarios as well. A method for determining and transmitting congestion information may be provided for a Wireless Local Area Network (WLAN) system. The method and apparatus may be used for managing congestion when congestion is detected. The method and apparatus may be used in wireless systems that use a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods may be implemented in wireless transmit/receive units (WTRU)s and access points (AP)s of various forms.
