摘要： 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.

摘要： 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 a 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 of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.

摘要： 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.

摘要： An access point includes a transmitter configured to transmit signals, a receiver configured to receive signals, and a timing information device. The timing information device is configured to receive a timing information request from a station associated to the access point, receive timing information for a beacon signal sent by a second access point, and report the timing information to the station, The timing information includes a time difference relative to a known reference time for transmission of the beacon signal and the time difference is an offset in timing units.

摘要： 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.
