<p>A method for improving synchro precision of data transmission and system thereof are disclosed. The method includes the following steps: RRU receives a data frame and buffers; frame-parses to a wireless frame impulse signal and a carrier wave data signal of the data frame, setting the maximum time-lapse compensating time; a time-lapse is redeemed to the wireless frame impulse signal after parsing, according to the time of transmission and buffering, and the maximum time-lapse compensating time, and then sends to the communication port of RRU to transmit; a time-lapse is redeemed to the carrier wave data signal after parsing, according to the time of transmission and buffering, the maximum time-lapse compensating time, and transmission time of processing data, the carrier wave data is processed, and then is sent to the communication port of RRU to transmit; the wireless frame impulse signal and the carrier wave data signal are sent to the communication port of RRU simultaneously. The solution redeems the carry time-lapse for transmission data, so that the redeeming precision can reach multiple seconds, thus improving synchro precision of the data in an effective manner.</p> |
