    Abstract: There are provided a method and apparatus for decoding an LDPC code. In this specification, a first result is calculated by performing the calculation of a check node having two inputs forward and recursively, a second result is calculated by performing the calculation of the check node having the two inputs backward and recursively, and the check node is calculated using the first result and the second result as the inputs.

    Abstract: Disclosed are a method and an apparatus for transmitting or receiving feedback information in a communication system. An operation method of a terminal comprises the steps of: receiving, from a base station, DCI #1 including scheduling information of PDSCH #1 and transmission resource information of HARQ response #1 with respect to PDSCH #1; receiving, from the base station, DCI #2 including scheduling information of PDSCH #2 and transmission resource information of HARQ response #2 with respect to PDSCH #2; and when the transmission resource information of HARQ response #1 is configured as undefined, transmitting, to the base station, HARQ response #1 and HARQ response #2 by using a resource indicated by the transmission resource information of HARQ response #2. Therefore, the performance of the communication system can be improved.
