摘要： In a communication system that includes a control station and dependent stations, the control station broadcasts data intended for the dependent stations on a per-superframe basis. The dependent stations relay the data received from the control station among themselves. If a dependent station has received the data transmitted from the control station, the dependent station transmits an acknowledgement response. If a dependent station does not receive an acknowledgement response from another dependent station, then the dependent station relays the data intended for the other dependent station.

摘要： A multiple control station transits a first broadcast frame including a first identifier for identifying a first host and a second broadcast frame including a second identifier for identifying a second host to a terminal station over a wireless channel using time division. The multiple control station then receives a connection request frame that requests connection with the first host or the second host from the terminal station. Arbitration is then performed so that the terminal station is connected to the first host or the second host in accordance with the first identifier or the second identifier included in the received connection request frame.

摘要： There is provided a communication control technique in which it is possible to avoid interference with another wireless communication system. This invention is characterized by a control station which controls wireless communication of dependent stations. When a dependent station newly starts, the control station determines whether a beacon transmitted by the dependent station is received by another wireless communication network. When determining that the beacon is received by the other wireless communication network, the control station instructs the dependent station to lower the transmission power until the beacon is not received.

摘要： A communication system makes throughput preferable by reducing wireless frame collision which occurs when a plurality of control stations cannot recognize one another. When a wireless communication device that is operating as a dependent station of a first control station detects a second control station, DEVice operates as a dependent control station. Accordingly, the second control station is changed to a dependent station or a dependent control station.

摘要： To adjust reception sensitivity suitable for avoiding cross-interference with another wireless communication system with an easy method. In order to achieve the above object, a control station that controls wireless communication of a dependent station determines whether or not a beacon received by the dependent station includes a beacon transmitted by a wireless terminal that is operated in asynchronization with the control station, and continues to transmit an instruction to lower the reception sensitivity of the dependent station to the dependent station until the beacon received by the dependent station does not include a beacon transmitted by the asynchronous wireless terminal.

摘要： In a radio communication system including terminals that access a control apparatus by a random access method, the number of collisions between data transmitted from the terminals is reduced. A control method for the control apparatus capable of communicating with at least one terminal located within a communicable range includes transmitting information designating a communication period in which the terminal transmits data to the control apparatus, changing a transmission range over which the information is transmitted, and transmitting, after transmitting first information designating a first communication period over a first transmission range, second information designating a second communication period which differs from the first communication period over a changed second transmission range.

摘要： A receiving apparatus includes a base-band conversion circuit, a synchronizing circuit/code generator and a demodulator. The base-band conversion circuit converts a received signal into a base-band signal. The synchronizing circuit/code generator detects a spread code included in the received signal to generate a plurality of spread codes in synchronization with the spread code included in the received signal. The demodulator uses the plurality of spread codes supplied by the synchronizing circuit/code generator to demodulate the base-band signal.
