摘要： A wireless communication method and system for optimizing channel selection for an AP. The channel selection optimization process includes four sub-processes: 1) a measurement process; 2) a candidate channel determining process; 3) a channel selection process; and 4) a channel update process. Candidate channels used for supporting communication performed by the AP are determined. The candidate channels are chosen from an allowable channel set (ACS) if a detected interference of each candidate channel is less than an established maximum allowed interference.

摘要： A primary station for a wireless communication system transmits and receives communications within a sectorized cell with at least one secondary station. The primary station transmits and receives signals within a beam; and directs the signal transmission and reception as a shaped beam. The shaped beam is directed at a plurality of predetermined directions; either continuously or discretely.

摘要： The present invention is a method and system for managing frequencies allocated to a cell within a cellular network to assign certain ones of those allocated frequencies for use by channel equipment within that cell. The method measures at least one quality metric for each of the allocated frequencies. At least one measured quality metric for the unassigned frequencies are compared against at least one quality metric for the assigned frequencies. An unassigned frequency is swapped for an assigned frequency based upon the comparison step. Additionally, a voting step is used to indicate that either the unassigned frequency or the assigned frequency has a higher signal quality for communication.

摘要： Malfunctioning or misbehaving mobile stations, that are capable nonetheless of continuing to communicate with a wireless communication system, are detected for the purposes of either shutting down misbehaving mobile stations or reporting misbehaving mobile stations so that corrective action can be taken. An error detector and interpreter detects in wireless communication signals received from a mobile station any breach of protocol errors indicative of faulty operation of the mobile station. A misbehavior analyzer analyzes the errors over time to determine whether the mobile station is misbehaving. Normal access of the mobile station to the wireless communication system is shut down or a message is sent to the subscriber in the event the mobile station is determined to be misbehaving. The mobile station also has a shutdown mode of operation, controllable by a message sent from the network, in which the mobile station remains idle and non-functional until repaired. The quality of service to subscribers using the wireless communication system is thus improved.

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.

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 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 and apparatus for admission control and resource tracking in a wireless communication system are disclosed. A wireless transmit/receive unit (WTRU) and a base station maintain parameters for admission control including parameters for the amount of time available for admission of traffic of each access category and for the amount of time available for admission of all access categories and parameters for admitted time and used time for the WTRU. Upon receipt of an admission request for a traffic stream from the WTRU, the base station determines whether to accept or deny the request based on the medium time for the requested traffic stream and the available time for the access category and total available time. The base station tracks the actually transmitted time by the WTRU, reclaims the unused time and returns the reclaimed time to either a common pool or to the WTRU as needed.

摘要： A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.
