Title:
CODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029205
Kind Code:
A1
Abstract:
Provided in the application are a coding method and a device. The method comprises the following steps: performing CRC (Cyclic Redundancy Check) coding on a number A of to-be-coded information bits to obtain a first bit sequence, wherein the first bit sequence comprises L number of CRC bits and A number of information bits; performing an interleaving operation on the first bit sequence to obtain a second bit sequence, wherein a first interleaving sequence used in the interleaving operation is obtained according to the longest interleaving sequence supported by the system and a preset rule. The length of the first interleaving sequence is equal to A+L, or a second interleaving sequence used in the interleaving operation is the longest interleaving sequence. the length of the second interleaving sequence is equal to K max+L, K max being the maximum number of information bits corresponding to the longest interleaving sequence; and performing polar coding on the second bit sequence. Therefore, in the distributed CRC encoding, when the number of information bits is less than the maximum number of information bits, the interleaving sequence required to complete the interleaving process is obtained according to the longest interleaving sequence supported by the system.
