摘要： The present invention relates to 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, the layered structure comprising at least a physical layer and a medium access layer. The communication system is arranged to offer a first type of service with a first priority order and a second type of service with a second priority order, in the communication system messages comprising a preamble and a payload can be transmitted between devices, each message being separated by at least a period corresponding to a minimum allowable period between two messages. In the method the first communication device first (a) generates (301) a physical layer message pertaining to the first type of service; (b) senses (303) the radio channel idle for at least a period corresponding to the minimum allowable period between two messages; and (c) transmits (305) the physical layer message comprising a special preamble indicative of the type of service the message pertains, wherein the content of the preamble is arranged to be detected by the second communication device within a communication range irrespective of the decoding state of the payload of the transmitted message.

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： A wireless network (1) comprises basic service sets (6, 7) and a distribution system (8). Each of the basic service sets (6, 7) comprises stations (2, 3) and stations (4, 5), respectively. Thereby, data is moved between their basic service sets (6, 7) and said distribution system (8) via access points (10, 11), which are also stations (3, 4). A medium access control architecture incorporating a distributed coordination function as an access method is provided. Thereby, a normal mode and a mesh mode are provided. Thereby, normal mode is used to transmit data between stations (2, 3; 4, 5) within each of the basic service sets (6; 7). In mesh mode, data is transmitted between the access points (10, 11). To priorize transmission within the distribution system (8) the stations (2, 5), which are not mesh devices, are silence during mesh mode. Therefor, one of the access points (10, 11) sends a request to send in which the address of the access point (10, 11) is used as both the transmitter address and the receiver address of this request to send.
