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 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.

Abstract: The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multi cast service (MBMS) data over a high speed down link packet access (HSDPA) channel. A Node B may pre-allocate a time frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.

Abstract: WIRELESS COMMUNICATION METHODS AND COMPONENTS THAT IMPLEMENT HANDOFF IN WIRELESS LOCAL AREA NETWORKS THIS INVENTION RELATES TO WIRELESS LOCAL AREA NETWORKS, AND 5 PARTICULARLY TO THE IEEE 802.11 FAMILY OF STANDARDS. IT CONSISTS OF A METHOD I AND APPARATUS THAT CAN BE IMPLEMENTED IN ACCESS POINTS (APS) AND SUBSCRIBER WIRELESS TRANSMIT/RECEIVE UNITS (WTRUS), IN ORDER TO ALLOW IN 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 10 BALANCING, CONGESTION CONTROL, AND ROAMING, WITHOUT COMPROMISING THE USER EXPERIENCE. FIG,URE 3

Abstract: A method for changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.

Abstract: A METHOD AND APPARATUS FOR EFFICIENTLY PROCESSING PACKETS FROM NEIGHBORING BASIC SERVICE SETS, (BSSS) TO CHARACTERIZE THE TAFFIC WITHIN A WIRELESS LOCAL AREA NETWORK (WLAN), MESH NETWORK, OR SIMILAR WIRELESS COMMUNICATION SYSTEM IS DISCLOSED. THE APPARATUS MAY BE AN ACCESS POINT (AP) IN A BSS WHICH INCLUDES A MEASUREMENT PERIOD (MP) INTERVAL TIMER, A PROMISCUOS MEASUREMENT PERIOD (PMP) TIMER AND A RECEIVER FILTER. AN INTERVAL OF THE MP INTERVAL TIMER IS SET WHILE THE RECEIVER FILTER IS ENABLED. DURING THE INTERVAL, THE AP ONLY PROCESSES PACKETS WHICH ORIGINATED FROM THE AP'S OWN BSS. WWHEN THE MP INTREVAL TIMER EXPIRES,AVALUE OF THE PMP TIMER IS SET TO A PREDETERMINED TIME DURATION AND THE RECEIVER FILTER IS DISABLED. DURING THE PREDETERMINED TIME DURATION, THE AP PROCESSES ALL RECEIVED PACKETS IRESPECTIVE OF WHICH BSS THE PACKETS ORIGINATED FROM. THE RECEIVER FILTER IS AGAIN ENABLED WHEN THE PMP TIMEJ- EXPIRES.
