摘要： In a communication system having a base station for controlling a transmission right and a plurality of substations, a substation having data to be transmitted transmits the number of necessary fragments and its address to a request field of a communication frame. The base station uses a plurality pair of fragment slots and reply slots following the request field in the communication frame to transmit an address of a substation permitted to transmit data, to each fragment slot. The substation permitted to transmit data transmits the address of a destination substation and the data to a predetermined field following the address in one fragment slot. The destination station transmits a reply signal indicating the reception state of the data to the reply slot paired with the fragment slot. If the base station detects from the reply signal that the destination station failed in receiving the data, the base station instead of the substation first transmitted the data transmits the destination address and data received at the fragment slot to the next fragment slot.

摘要： In a wireless communication system having a plurality of base stations connected through a control line and a plurality of mobile terminals, one of base stations (a master base station) informs a carrier frequency hop timing to the other base stations (slave base stations) through the control line. Each slave base station generates a wireless communication frame used inside of each cell and switches the carrier frequency of the wireless communication frame in synchronous to the timing indicated by the master base station. Each movable terminal receives an identifier of a frequency hopping sequence from a control information field of the wireless communication frame, hops to one carrier frequency selected among a frequency hopping sequence corresponding to this identifier, and transmit or receive the data through the field following the control information field of the wireless communication frame.
