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 data communication frame is formed by a preamble portion (PREAMBLE) for demodulation and synchronization, a frame information portion (FC) containing a data type of the frame, a frame length portion (FL), and a data body portion (DATABODY) composed of more than one data packet combined together. If a request to transmit a packet is made from an upper layer, a communication apparatus 10 concurrently performs a process of calculating a frame length the frame would have if combining of the packet is performed and a process of transmitting the preamble portion and the frame information portion. The frame length depends on packets, while the preamble portion and the frame information portion do not depend on packets.
