1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, information configuring a limited buffer rate matching (LBRM);
encoding data bits using a low-density parity check (LDPC) code;
identifying a value based on at least one parameter included in the information, the value including one of a maximum value or a minimum value of a maximum number of layers;
determining a limited range of parity bits for the LBRM, based on the value;
performing the LBRM based on the encoded data bits and the limited range of the parity bits; and
transmitting, to the base station, at least one data bit of the encoded data bits, based on the LBRM.
