Abstract: A method for power allocation in a dAP may comprise: when a change cycle of a transmit power determination vector arrives, generating an uplink message including long-term CSI, the uplink message being normalized such that the long-term local CSI becomes a value within a preconfigured limit range; transmitting the uplink message to a central processing unit through a fronthaul; receiving a downlink message vector for power allocation from the central processing unit through the fronthaul; generating decentralized determination information using the downlink message vector; and extracting a transmit power determination vector based on the decentralized determination information.
