Disclosed is an HARQ combination method, including: receiving a relevant parameter of HARQ combination configured externally, calculating an identifier ddr2switch of DDR2 switch, and acquiring addresses before and after HARQ combination; judging whether HARQ combination is required according to the relevant parameter and the addresses before and after HARQ combination, if it is required, then reading the data in DDR2 and storing the data in a first data cache RAMA; and performing HARQ combination calculation and storing the calculation result in a second data cache RAMB. Also provided is an HARQ combination device. The technical solution in the present invention greatly improves successful coding probability based on the latest interference cancellation algorithm, saves storage space of DDR2, and improves the read-write efficiency. |
