Provided is a communication method executed by a relay apparatus including a relay device that performs relay transmission of relaying a radio signal transmitted between a network node and a user equipment, and a control terminal used to control the relay device, the communication method including: receiving, by the control terminal, power control information for controlling a transmission power of the relay transmission from the network node; and performing, by the relay device, the relay transmission at the transmission power based on the power control information. The power control information includes at least one selected from the group consisting of first information indicating a maximum transmission power and/or a maximum gain to be set in the relay device, second information indicating a transmission power and/or a gain in periodic relay transmission, and third information indicating a transmission power and/or a gain in aperiodic relay transmission.
