摘要： A method for negotiations between various entities of a wireless local area network (WLAN) including negotiations between controlling nodes (CNs) and wireless access points (WAPs) and negotiations between WAPs is disclosed. These negotiations are used for the purpose of establishing the capabilities of the various entities, determining how such capabilities may be optimally divided among the negotiating entities and then dividing the capabilities among the entities based on this determination. The capabilities include those required for the operation, control and management of the WLAN entities and the encompassing WLAN. The disclosed method introduces means for flexibly accommodating the varying degrees of differences in capabilities among the WLAN entities between the WLAN entities including dynamic changes in WLAN topologies.

摘要： A method and system are disclosed that can be applied to achieve high-throughput in a WLAN. Central to the present invention is the use of an SDMA compatible multi-beam antenna system by a WLAN access point. A system based on two types of antennas-dynamic beam forming and fixed beam antennas—is described. A mechanism and protocol are described that implement simultaneous transmissions with respect to an SDMA compatible access point and thereby improve spectral efficiency, and by extension achieve higher throughput. Based on the recognition that current WLAN MAC has major limitations in throughput, certain MAC extensions (that can be applied independently of SDMA) are described. Also disclosed are power-saving and power control techniques that improve battery performance and contribute to a reduction in station size, and a means of reducing channel interference. The present invention also deals with the problem of backward compatibility with conventional devices that implement the protocol that is a subset covered by the present invention.

摘要： Disclosed is a technique to provide a QoS resource reservation method and the like, which will not generate a delay in establishing a QoS reservation and can avoid the waste of QoS resources. According to the technique, the method includes: a step of causing a mobile node 110 to send, toward a corresponding node 100, a first message to collect information for making a QoS resource reservation; and a step in which, when the mobile node detects a handover thereof during QoS resource reservation processing, the mobile node sends a second message to a path from the mobile node before the handover to the corresponding node to remove the QoS resource reservation.

摘要： A technique is disclosed to decrease unnecessary routing during communication between a mobile node and a correspondent node in case a home agent of the mobile node is a mobile home agent. According to this technique, HA 112 positioned in a home network 102 and HA 114 of MN 130 are included. In a communication system, where HA 114 is a mobile home agent, and a mobile network 104 of HA 114 is hierarchized under the home network 102, HA 114, which is a home agent, discovers HA 112 positioned in the home network 102 when it is detected that it is away from the home network 102 and delegates binding cache entry of MN 130 under its own management to HA 112 so that HA 112 acts as a home agent for MN 130.

摘要： The present invention provides a method and system for efficiently scheduling wireless LAN traffic, giving the network the ability to serve both real-time and non-real time applications concurrently, while maintaining a requested level of quality of service for the real time application. It describes a method for scheduling quality of service traffic and a method to optimize this schedule thereby reducing the overall amount of time that is required for serving quality of service traffic (which is coordinated by a centralized network coordinator entity) and increasing the bandwidth available for non-real-time traffic. One application of such a scheduler would be WLANs that carry AV streams, such as may be found in a home based WLAN. Furthermore, a method is provided for announcing the schedule to all nodes in a wireless network to, for example, implement a power savings feature, thereby optimizing battery life and reducing the size and weight of portable network access terminals.

摘要： The invention includes methods for achieving efficient channel access in a wireless communications system. The invention is embodied in a wireless network adapter that is present in all stations belonging to the network. The invention describes methods by which access overheads may be reduced by introducing the concept of context sensitive frame timing—using which stations redefine and interpret frame timing depending on context and signaling. The result of realizing the invention is an improvement in medium utilization efficiency and consequently, an overall improvement in network throughput.

摘要： A wireless transmission apparatus that improves throughput in a wireless communication network system. In this apparatus, MT units of transmission/reception sections (122-1 to 122-MT) respectively correspond to MT units of antennas (121-1 to 121-MT) and transmit a preamble signal and a data signal via corresponding antennas (121-1 to 121-MT). MT units of transmission/reception sections (122-1 to 122-MT) use subcarriers allocated per antennas (121-1 to 121-MT) out of subcarriers (141, 142, 143 and 144) in preamble signal transmission. Furthermore, MT units of transmission/reception section (122-1 to 122-MT) use a subcarrier (140) having a frequency different from subcarriers (141, 142, 143 and 144) in data signal transmission.

摘要： A carrier sense multiple access method capable of improving throughput in a wireless network is disclosed. This method is implemented in a wireless network—for example, a wireless LAN (100)—having an AP (110) that is equipped with a multi-beam antenna (111) that forms a directional beam and that is capable of SDMA, and a STA (120, 130, 140) that communicate with the AP (110). With this method, the AP (110) allots the STA (120 to 140) to a beam group defined by a coverage area of the directional beam, according to the location of the STA (120 to 140). Then, the allocated STA (120 to 140) is assigned a signature signal for group identification, the signature signal being unique to the group.

摘要： A method for performing selective updating procedure of service advertisements. In this method, a Master personal gateway (10a) chooses a Slave personal gateway (10c) to update from its service list (step 40). The Master personal gateway (10a) uses the service description stored in its service list to determine if the Slave personal gateway (10c) of PAN (21c) has the capabilities to use the service advertised (step 41). The Master personal gateway (10a) then forwards the service advertisement to the Slave personal gateway (10c) (step 42). The Slave personal gateway (10c) updates its service list and advertises the service within its PAN (21c) (step 43).
