Method for channel coding in wireless communication system and apparatus therefor

A method for a transmitting end device to transmit a first type signal for a first type wireless communication system and a second type signal for a second type wireless communication system, the method comprising:

• receiving, from a receiving end device, a configuration indicating a first type channel encoding and a second type channel encoding based on system requirements;
• performing the first type channel encoding for the first type signal to be transmitted via the first type wireless communication system;
• performing the second type channel encoding for both of the first type channel encoded-first type signal and the second type signal to be transmitted via the second type wireless communication system;
• transmitting the first type signal to the first type wireless communication system and the second type wireless communication system;
• and
• transmitting the second type signal to the second type wireless communication system,
• wherein the method further comprises:
• reconfiguring the second type channel encoding when the system requirements of at least one of the transmitting end device and the receiving end device are changed;
• and
• transmitting, to the receiving end device, information about the reconfigured second type channel encoding via a default channel to which only the first type channel encoding is applied.
