Title:
RETRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/042214
Kind Code:
A1
Abstract:
Disclosed in the present application are a retransmission method and device for a Polar code. The method comprises: a transmitting device performing new encoding on bits to be encoded in each segment to obtain an encoded first bit sequence, the length of the first bit sequence being N0, and determining an initial transmission version RV0; determining a length E1 of a retransmission version RV1; determining the retransmission version RV1 according to an initial transmission code rate R0; and determining retransmitted data according to the RV0 and /or the RV1. The method implements retransmission in a simple and convenient manner on the basis of meeting existing standards.
