Title:
METHOD, COMMUNICATION DEVICE, PROCESSING DEVICE, AND STORAGE MEDIUM FOR PERFORMING CHANNEL ENCODING, AND METHOD AND COMMUNICATION DEVICE FOR PERFORMING CHANNEL DECODING
Document Type and Number:
WIPO Patent Application WO/2022/260469
Kind Code:
A1
Abstract:
A communication device: performs LBRM for storing, in a circular buffer having the length N_IR, N_IR coded bits from among coded bits obtained by performing encoding on the basis of a polar code; performs rate matching on coded bits stored in the circular buffer; and transmits the rate-matched coded bits to another communication device. The communication device stores, in the circular buffer, last N_IR bits from among the coded bits if a code rate is less than or equal to a predetermined value, and, if not, stores first N_IR bits in the circular buffer.
