Abstract
The disclosure relates to a method performed in a 5G or 6G communication system for supporting a higher data transmission rate than that of a 4G communication system such as LTE and, for example, to a low density parity check (LDPC) encoding method and apparatus capable of variably performing a method for maximizing an encoding gain or minimizing decoding latency by variably applying puncturing of data bits when determining encoding bits.
Claims15
A method performed by a transmitting apparatus in a communication system, the method comprising:
