PURPOSE:To reduce collisions of control signals right after the end of a control signal transmission inhibition time zone by transmitting a newly generated control signal right after the inhibition time zone and a resent control signal an irregular time interval after the end of the control signal transmission inhibition zone. CONSTITUTION:Mobile stations (a) and (b) have timing points of resending at points 8 and 14 of time which are TD+TR1 and TD+TR2 later respectively unless a response to a control signal is obtained from a radio ground station even a certain time later. The points 8 and 14 of time, however, are in the control signal inhibition time zone Fa, so mobile stations (a) and 32-b wait until Fa end time t1 and then resend control signals TR3 and TR4 later respectively since they are in resending operation. A mobile station (c), however, is to transmit a newly generated control signal at the point 18 of time, but the point of time is in the control signal inhibition time zone Fa, so the station waits until t1 and then starts sending the signal. |
