  • the time width of one slot is set to 625 ⁇ s
  • the time lengths of the upstream frame 200U and the downstream frame 200D are 2.5 ms, respectively
  • the time length of the unit TDMA / TDD frame Is 5 ms.
  • the communication terminal 30A After receiving each control information transmitted from a plurality of base stations, the communication terminal 30A specifies a base station to be connected based on each control information. Then, the communication terminal 30A synchronizes the frame timing with the connection target base station (connection base station), and transmits a channel request to the connection base station. The transmission of the channel request is performed at a timing at which the common channel is allocated in the connected base station. For example, when the base station 10A is selected as the connection base station, the channel request is transmitted in an uplink time slot in a frame synchronized with the timing of intermittent transmission of control information by the base station 10A.
  • the communication terminal 30A specifies a base station to be connected based on a plurality of received control information, and then transmits a channel request to the connected base station.
  • the transmission of the channel request is controlled so as to be executed at a timing at which the common channel is allocated in the connected base station.
  • the base station 10A is selected as the connection base station
  • the channel request is transmitted in the uplink time slot in the frame synchronized with the intermittent transmission frame. That is, the communication terminal 30A performs control so that the channel request is transmitted in a frame synchronized with the TDMA / TDD frame 200E including the time slots BU12 and BD12 to which the common channel is allocated in the base station 10A.
  • initial communication using the common channel is first performed between the base station 10B and the communication terminal 30A, and unique communication is performed between the base station 10B and the communication terminal 30A. Established. Then, after the establishment of the unique communication, individual communication using an individual channel is performed between the base station 10B and the communication terminal 30A.
  • a first timing and a second timing are defined between the base station 10B and the communication terminal 30A.
  • the first timing and the second timing are based on a frame in which the allocation of the dedicated channel is notified from the base station 10B to the communication terminal 30A.
  • FIG. 8 is a diagram for explaining a first timing defined between the base station 10B and the communication terminal 30A
  • FIG. 9 illustrates a second timing defined between the base station 10B and the communication terminal 30A. It is a figure for demonstrating timing.
  • the communication terminal 30A since the transmission / reception timing is determined as the first timing, the communication terminal 30A includes the transmission process based on the received allocation information in the frame 200HM next to the frame 200GM that has received the allocation information. Transmission time slot MU22.
  • the allocation information from the base station 10B to the communication terminal 30A passes through the relay device 50 once, there is 0.5 frame worth between the first timing of the base station 10B and the first timing of the communication terminal 30A. A shift has occurred. Furthermore, since the information transmitted at the first timing in the communication terminal 30A passes through the relay device 50, the information is delayed by 0.5 frame. Therefore, in a series of communications in which downlink and uplink are combined, there is a total delay of one frame when the base station 10B receives the information transmitted at the first timing of the communication terminal 30A. .
  • the relay device 50 delays the signal from the relay source by 0.5 frame and relays it to the relay destination.
  • the present invention is not limited to this, and the delay amount in the relay device 50 is changed. can do.
