Example Embodiment
[0034] In the embodiment of the present invention, considering that the ACK / NACK repetition mechanism is used in the TDD system, the eNB makes a judgment after receiving the last ACK / NACK to decide whether to retransmit the failed data or to send new data. Since the mobile communication terminal starts the HARQ RTT Timer when receiving the downlink data transmission instruction, and then according to whether the downlink data is correctly received, the number of consecutive uplink subframes after the downlink data is reached, and according to the configured number of retransmissions, the base station reports whether there are multiple To correctly receive the indication information ACK or NACK of the downlink data, the eNB will make a decision after receiving the last ACK or NACK. If the decision result is NACK, the downlink data will be retransmitted. Therefore, the best timing duration T1 of the HARQ RTT Timer is three parts The sum of time is calculated according to the follo...
