摘要： A communication apparatus improves the throughput of a whole communication system while performing contention distributed control which provides equality of a transmission chance by observing a medium occupation state. The communication apparatus includes a back-off process section for performing, using a contention window, a regular back-off process which is performed at transmission of a transmission frame and a pseudo back-off process which is performed in a pseudo manner when the transmission frame is not transmitted. The communication apparatus also includes a medium information obtaining section for obtaining, by the pseudo back-off process, medium information indicative of a state of the transmission line medium when the transmission frame is not transmitted, and a medium state determination section for determining the state of the transmission line medium using the medium information to obtain determination information.

摘要： A communication band is divided into: a beacon period in which every master station transmits a beacon packet in competition with one another; a guaranteed-band period (e.g., a TDMA period or an FDMA period) in which only a specific permitted station is allowed access; and a CSMA period in which every station is allowed access in competition with one another. Plural master stations exchange information of a communication band used in the guaranteed-band period with each other, and based on the respective information, a communication band available to the master station's own communications system in the guaranteed-band period is calculated.

摘要： Terminal devices F and G store statistical information related to interference from an external communication system, and notify the stored statistical information to a master station E. The master station E determines the terminal device G as a candidate station for a master station capability handover destination based on collected statistical information. The master station E requests to hand over a master station capability to the terminal device G. If it is determined that the terminal device G accepts handover of the master station capability, the terminal device G starts to act as the master station.

摘要： A communication bandwidth is divided into a beacon period in which all master stations compete for transmission of a beacon packet, a first carrier sense multiple access (CSMA) period in which only authorized specific stations are allowed to compete for access, and a second CSMA period in which all stations are allowed to compete for access. The master stations exchange information with each other about a communication bandwidth being used in the first CSMA period, thereby calculating a communication bandwidth which can be used by each communication system in the first CSMA period, based on the information.

摘要： A medium access control method is provided in which a control station transmits one specific frame to terminal stations, thereby arranging a schedule of a data transmission time of the control station and each of the terminal stations and allowing a time zone unused by a station for data transmission to be allocated to another station. The control station transmits a schedule frame having defined therein a time occupied by each of the terminal stations, thereby reducing overhead. Also, the completion of the preceding communication performed by another station is detected, thereby effectively using an idle time of a medium and improving transmission efficiency.
