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.

Abstract: A near-infrared-absorption white material, a method of manufacturing the same, and uses thereof. The near-infrared-absorption material includes copper pyrophosphate compound. The copper pyrophosphate compound has a brightness (CIE L*) value of 90 or more in a visible-ray region and is excellent in particle manufacturing properties, and a crystalline structure of the copper pyrophosphate compound is made chemically stable using a heat treatment at a high temperature. The copper pyrophosphate compound is represented by the following chemical formula: Cu2P2O7 or Cu2P2O7.XH2O (x=1-3).
