The present application discloses a method for merging a plurality of different data blocks. The method comprises the steps of: assuming sending serial number n of an ith data block in a current period, based on the current assumption serial number of the ith data block, setting serial numbers for all the received data blocks in order to form a sequence relation; according to the difference sequence between data blocks corresponding to the sequence relation, performing partial inversion of the data blocks in the current period; according to the sequence relation, merging each inverted data block and each non-inverted data block; and performing decoding and verification of the merged data blocks. The possible serial numbers of the data block I is traversed to try merging and decoding and verification. The merging of the different data blocks in the 5G communication technology is solved to allow the receiving terminal to obtain the gain of the retransmission.
