Abstract:
1. A signal transmission method in a TDD system, comprising: within a time length of a half-frame of a radio frame, a base station transmitting signals in a downlink special time slot, thereafter not transmitting signals in a guard period (GP), and then receiving signals in an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signals being equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot being integer times of the time length of one uplink or downlink normal time slot; and wherein the number of the uplink and downlink normal time slots in the half-frame is 4, 5, 6, 8, 10, 11, 12, 13 or and within the time length of the half-frame base station transmits signals in order in the first downlink normal time slot, in the second downlink normal time slot and in the downlink special time slot, thereafter does not transmit any signal in the GP, and then, receives signals in the uplink special time slot, and receives or transmits signals in the remaining 6 time slots according to uplink and downlink setting and the total time length of the downlink special time slot, the GP and the uplink special time slot is 2 times of the time length of one normal time slot.
