Title:
ENCODING METHOD AND DEVICE, DECODING METHOD AND DEVICE, AND APPARATUSES
Document Type and Number:
WIPO Patent Application WO/2018/196683
Kind Code:
A1
Abstract:
The present application provides an encoding method and device, a decoding method and device, and apparatuses. The encoding method comprises: a transmitting apparatus determines information bit positions, fixed bit positions, and auxiliary bit positions, and configures information bits, fixed bits, and auxiliary bits in a sequence to be encoded according to the determined positions; acquire a scrambling sequence, determine a set of bits to be scrambled in the fixed bits and/or the auxiliary bits, and scramble bits in the set of bits to be scrambled according to the scrambling sequence to obtain a scrambled sequence; then perform polarization encoding to obtain an encoded sequence for transmission. A receiving apparatus performs decoding verification after receiving a sequence to be decoded, performs verification when decoding is performed to the position of a scrambled bit, and if the verification fails, ends the decoding process. The invention can exclude a signal which does not belong to the transmitting apparatus in advance, reduce decoding delay, and speeds up testing.
