Embodiment 1
[0028] Such as figure 1 and figure 2 As shown, the signal transmission method of this embodiment includes the following steps:
[0029] 1) The burst frame is used as the basic unit for transmission, and each burst frame occupies a carrier frequency, which includes a time slot Slot1 and a time slot Slot2.
[0030] 2) The transmitting terminal MS1 transmits signals to the relay station BS and the receiving terminal MS2 in the time slot Slot1 of the carrier frequency, and at the same time the receiving terminals MS2, MS3, and MS4 receive the signals directly transmitted by the transmitting terminal MS1;
[0031] 3) The relay station BS receives the signal in the time slot Slot2 of the carrier frequency, and after the receiving state is switched to the forwarding state, it forwards the signal in the time slot Slot1 of the carrier frequency;
[0032] 4) The receiving terminals MS2, MS3 and MS4 receive the signal forwarded by the relay station BS in the time slot Slot2 of the car...
