Title:
HYBRID AUTOMATIC REPEAT REQUEST (HARQ)-BASED COMMUNICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/135068
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of communications, and provide an HARQ-based communication method. The method comprises: acquiring a plurality of information bits in a first transmission; dividing the plurality of information bits into m groups of first information bit sequences K1, ..., Km; encoding the m groups of first information bit sequences to obtain a first target encoded code word; sending the first target encoded code word to a receiving end; if the first transmission fails, interleaving, in a t-th retransmission, n groups of first information bit sequences among the m groups of first information bit sequences to obtain m groups of first bit sequences X1, ..., Xm; encoding the m groups of first bit sequences to obtain a second target encoded code word; and sending the second target encoded code word to the receiving end. In this way, in the HARQ-based implementation mode, some information bit sequences are interleaved in the retransmission process, and the interleaving processing can improve the code redistribution in the transmission, and thus a better coding gain is obtained.
