1. A method for controlling data retransmission, comprising:
transmitting data to a network device and starting a timer; and
retransmitting the data after the timer expires, if a HARQ-ACK feedback corresponding to the data is not received before the timer expires;
retransmitting the data if a HARQ-NACK feedback corresponding to the data is received from the network device before the timer expires; wherein retransmitting the data comprising:
obtaining a time resource for retransmission according to the timer;
obtaining a frequency resource for retransmission according to previous transmission; and
retransmitting the data with the time resource and the frequency resource; wherein a location of the time resource is determined by: T+N, wherein T is the time when the timer expires, and N is a predetermined parameter; wherein a location of the frequency resource is determined by: RB +offset, wherein RB is a location of a frequency resource for transmitting the data before the retransmission, and offset is a predetermined parameter.
