1. A radio communication node communicating with an Integrated Access and Backhaul (IAB) donor operating as a parent node relative to the radio communication node, communicating with a child node relative to the radio communication node, and communicating with a terminal, comprising:
a receiver that receives a first downlink signal from the IAB donor; and
a transmitter that transmits, to the IAB donor, a first Medium Access Control-Control Element (MAC CE) including a first value for controlling transmission power of the first downlink signal,
wherein the transmitter transmits, to the child node, a second MAC CE including a second value for controlling transmission power of a second downlink signal transmitted to the child node.
