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 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 and apparatus for exchanging messages via a wireless distribution system (WDS) between groups operating on different frequencies are disclosed. A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) and a plurality of basic service sets (BSSs). At least one WTRU belongs to each BSS. A source WTRU desiring to send a WDS packet to a destination WTRU in another BSS sends an availability notification (AN) message to WTRUs which the source WTRU is associated with to indicate that the source WTRU will not be available to receive data. The source WTRU then accesses a channel on which the destination WTRU camps and sends a packet to the destination WTRU. After transmission of the packet, or receiving an acknowledgement from the destination WTRU, the source WTRU reverts back to the original channel.

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： In a wireless communication system, (e.g., a wireless local area network (WLAN)), including a plurality of wireless transmit/receive units (WTRUs) and a coordinating node, (e.g., an access point (AP)), path loss is estimated by transmitting a loud packet from a first one of the WTRUs to a second one of the WTRUs. The coordinating node transmits a loud packet generation request message. A first one of the WTRUs receives the loud packet generation request message and transmits at least one loud packet at a transmission power specified by the loud packet generation request message. Optionally, the first WTRU transmits a loud packet generation response message. A second one of the WTRUs receives the loud packet and determines a path loss between the first WTRU and the second WTRU by subtracting the signal strength of the loud packet from the determined transmission power of the loud packet.

摘要： A method and system for performing peer-to-peer wireless communication between stations (STAs) within a basic service set (BSS) while maintaining connectivity with an access point (AP) in the BSS are disclosed. A source STA, an AP and a destination STA negotiate a direct link setup (DLS) channel for performing peer-to-peer communication between the source STA and the destination STA. The DLS channel may be different from a BSS channel used for communication between the AP and each of the STAs. The source STA and the destination STA then perform peer-to-peer communication on the negotiated DLS channel.

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.
