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： An access point in a wireless local area network may receive an information request from a station associated with the access point. The information request is requesting information about a second beacon transmission associated with a service set identifier (SSID) different from an SSID of the access point. The access point includes a timing information device configured to generate an information response for a beacon signal associated with the SSID different from the SSID of the access point. The information response may include a time difference, relative to a beacon signal sent by the access point, for transmission of the beacon signal associated with the SSID different from the SSID of the access point. The time difference may be an offset in timing units. The access point also includes a transmitter configured to transmit the information response to the station in response to receiving the information request.

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： 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.
