Abstract
A transmission method of a time division duplex mobile communication system according to the present invention is characterized in that a minimum unit of transmission time interval and a system frame structure are provided and each radio subframe includes one downlink pilot time slot, one switching guard time slot, And a transmission time interval is a unit of a length of a time slot. The user acquires downlink synchronization by receiving downlink pilot information of a downlink pilot time slot, and obtains cell broadcasting information The arrangement information includes the transmission time interval and the system frame structure information. The user then completes the random access procedure by transmitting the uplink synchronization information in the synchronization time slot, Side / user transmits call information to the other party, And the network side includes allocating channel resources to the user, and the network side and the user communicating through the allocated channel. The present invention reduces data transmission delay during communication and improves call throughput.
