1. An operation method of a receiving node in a communication system, the operation method comprising:
receiving, from a transmitting node, mapping information between transmission parameters and aggregation factors (AFs);
receiving a message including information indicating whether to use the mapping information from the transmitting node;
receiving, from the transmitting node, control information including a first transmission parameter used for transmission of data among the transmission parameters;
determining a first AF mapped to the first transmission parameter from among the AFs based on the mapping information when the message indicates use of the mapping information, or determining a first AF based on other information instead of the mapping information when the message does not indicate use of the mapping information;
performing a first repetitive reception operation on the data transmitted from the transmitting node based on the first AF;
generating a reception response of the data when a number of receptions of the data is equal to the first AF;
informing the transmitting node of the reception response;
informing the transmitting node of information used for changing the first AF to a second AF; and
performing a second repetitive reception operation based on the second AF,
wherein the reception response means a reception failure when all results of all receptions of the data are failures, or the reception response means reception success when a result of at least one reception among all receptions of the data is successful, and
the second AF is determined by the transmitting node based on the information used for changing the first AF to the second AF.
