US 2023/0171025 A1 · DATA DECODING METHOD AND DEVICE IN COMMUNICATION AND BROADCAST SYSTEM

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Further, the present disclosure relates to decoding of a turbo code in a communication system including long term evolution (LTE), and to efficiently implement a method, procedure, and device for receiving and decoding a signal transmitted in a mobile communication system.

Claims14

Dependent claims

A method performed by a receiving device of a communication system comprising:

determining whether decoding on an estimated bit sequence has failed;
determining, based on the decoding being determined to be unsuccessful, whether to perform a post-processing based on whether a code parameter satisfies a specified condition;
identifying, based on the post-processing performance determined to be performed, one bit index corresponding to the specified condition;
and
performing decoding of an external concatenated code based on a modified bit sequence in which the bit corresponding to the identified one bit index in the estimated bit sequence is inverted.
