redundancy version design solution in communications system

摘要

this order discloses an information processing method, an apparatus, a communications device, and a communications system. the communications device is configured to determine a redundancy version transmission sequence, wherein the redundancy version transmission sequence is used to indicate a sequence of sending a plurality of redundancy versions; determine a transmission number; and obtaining a redundancy version from a buffer sequence based on the redundancy version transmission sequence and the transmission number and sending the redundancy version. the communications device can be applied to a communications system supporting a plurality of redundancy version transmission streams, for example, a 5th generation (5g) communications system. as the redundancy version transmission sequence is determined before data transmission, communication efficiency is improved, and harq performance is improved.
