A transmitting method and system for short physical random access channel based on time division duplex system are provided, in the said method, the short physical random access channel is transmitted in uplink particular time slot, and the persisting time of the short physical random access channel is same at the condition of short cyclic prefix or long cyclic prefix being adopted in the uplink particular time slot. The reliability of Short-PRACH is enhanced, the complexity of random access is reduced and the cost is saved by the present invention. |
