A METHOD, DEVICE AND SYSTEM FOR HYBRID AUTOMATIC REPEAT

摘要

A method, device and system for hybrid automatic repeat are disclosed. The transmitter side transmits a number of data units to the receiver side in the same time transmission internal; the receiver side demodulates, decodes and checks every data unit and transmits the response information corresponding to whether every data unit is right or not to the transmitter side; the transmitter side retransmits the data unit which is not transmitted successfully within the HARQ maximum transmission time according to the response information; after receiving the retransmitted data unit, the physics layer of the receiver side combines, demodulates, decodes, checks, orders and stores, and transmits the response information corresponding to whether the corresponding every data unit is right or not to the transmitter side. The invention can effectively save the physics resource, reduce the processing time for the data block and increase the efficiency of data transmission.
