The invention relates to a mobile communication technology, and provides a control method for downlink data reception in a TDD system and a mobile communication terminal, wherein the control method is used for reducing the electric power consumption of the mobile communication terminal. In the embodiment of the invention, when a technology of repeatedly sending ACK or NACK is adopted in the TDD system, the timing duration of a HARQ RTT Timer is set as the length which is smaller than or equal to T1 and larger than or equal to T2 and is multiples of the endurance time of any single subframe, and under the condition of ensuring the reception of retransmission data which is possible to reach within the shortest time, compared with a mode of directly adopting the set timing duration of the HARQ RTT Timer when the ACK or the NACK is not repeatedly sent, the electric loss of the mobile communication terminal is saved.
