Title:
COMMUNICATION DEVICE AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/107452
Kind Code:
A1
Abstract:
This communication device comprises: an encoding unit that generates a second encoded bit string by encoding, via a second encoding method, a frozen bit string and a second bit string, the second bit string being constituted by a first bit string and a first encoded bit string generated by encoding, via a first encoding method, the first bit string; and a transmission unit that transmits a transmission signal generated from the second encoded bit string; wherein the second encoded bit string is determined on the basis of the length of the second bit string.
