    摘要： The present invention relates to a method of reducing beacon collision probability in a communication network supporting control channels comprising beacon periods divided into beacon slots, each beacon period being followed by a contention period. In the method a communication device (101) operating in the communication network first chooses (503) an available beacon slot for transmission of a first type of beacon for exchanging network topology information with other communication devices operating in the communication network. Then the communication device transmits (515) a beacon of a second type comprising an identifier of the communication device and the chosen beacon slot for the transmission of the beacon of the first type, the beacon of the second type being transmitted in the contention period.

    摘要： The present invention is directed to an apparatus and method for connecting a mesh type network via an access device to another network, wherein a proxy mechanism is provided in the mesh type network, that allows for interconnection and range extension of legacy access point based mesh type networks. Thereby, interconnection and range extension of e.g. legacy AP-based WLANs or similar types of networks can be achieved. Moreover, the proposed proxy mechanism does not require any changes or modifications to the access device(s) (e.g. AP) and works with any type of access device.

    摘要： A congestion control method for a communication system supporting layered radio channel structure for communication between at least a first communication device and a second communication device that offers a first and second types of service with corresponding first and second priority orders. The messages between devices include a preamble and a payload with each message being separated by at least a minimum allowable period. The first communication device generates a physical layer message pertaining to the first type of service, senses the radio channel idle for at least a period corresponding to the minimum allowable period between two messages, and transmits the physical layer message including a preamble indicative of the type of service the message pertains. The content of the preamble is detected by the second communication device within a communication range irrespective of the decoding state of the payload of the transmitted message.

    摘要： A method for the operation of wireless base stations for packet transfer radio systems having guaranteed service quality. The method includes increasing the supply ranges of packet oriented transferring radio stations, which are located outside the range of the central base stations and are supplied by wireless base stations (relay stations). In contrast to conventional wireless transfer systems, a communications service quality is guaranteed. A common time interconnected capacity assignment method is used. The capacity assignment is generated for an access point (AP) by mobile and forward terminals (MT, FMT) which can be reached directly. Individual MTs are present in the form of wireless base stations and serve as relay stations (FMTs) for the MTs outside the range of an AP. For an AP, FMTs appear as MTs. The FMT forms a partial frame structure in a part of the AP distribution capacity transfer system, which is embedded in the time frame structure dictated by the commanding central station. Adherence to a required service quality guarantee is achieved by capacity assignment algorithms.
