Abstract: An operation method of a relay base station in a communication network including a central base station, the relay base station, and a terminal may comprise receiving a request message for requesting a low latency service from the terminal; in response to the request message, measuring a signal quality of a radio link between the central base station and the relay station and a signal quality of a radio link between the relay base station and the terminal; determining whether to support the low latency service based on the signal qualities; and when the low latency service is determined to be supported, transmitting downlink data received from the central base station to the terminal without performing modulation and demodulation operations, or transmitting uplink data received from the terminal to the central base station without performing modulation and demodulation operations.
