<p>Disclosed are a method and device for data retransmission and merging based on a hybrid automatic repeat request (HARQ). The method includes: when receiving the data of the Nth transmission of a data packet, merging the data of the Nth transmission of the data packet, and performing the following operations on each coding block of the data packet: determining a weighted merging weight value of the coding blocks to be merged when merging data in the data of each transmission according to the signal-to-interference and noise ratio of the coding blocks to be merged in the data of the Nth transmission; performing data merging on the coding blocks to be merged in the data of the Nth transmission according to the determined weighted merging weight value; and obtaining the merged data of the data packet until the data of all coding blocks in the data packet has finished merging. The influence of channel state is considered when merging data, and the data merging is performed according to the weight, increasing the correct rate of merging data, and improving system performance.</p> |
