Title:
METHOD AND DEVICE FOR USE IN USER DEVICE AND BASE STATION FOR CHANNEL ENCODING
Document Type and Number:
WIPO Patent Application WO/2018/127161
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and a device for use in a user device and a base station for channel encoding. A first node determines a first bit block, executes channel encoding, and sends a first wireless signal. The bits in the first bit block are used for generating the bits in a second bit block. The bits in the first bit block and the bits in the second bit block are used for channel encoding input, and the channel encoding output is used for generating the first wireless signal. The channel encoding is based on a polar code. The number of sub-channels occupied by a target first bit type is related to the number of bits in the second bit block related to the target first bit type. The target first bit type belongs to the first bit block. The present invention can improve polar code decoding performance and reduce decoding complexity.
