Deep learning-based power control method for user-centric network
ActiveCN110401964AImprove performanceImprove service qualityPower managementRadio transmissionActivation functionPower control algorithm
The invention provides a deep residual error network named as UcnNet, and a weighted minimum mean square error (WMMSE) algorithm of a real number domain under a network (UCN) taking a user as a centeris fitted. Specifically, in order to effectively manage the coupling interference in the UCN, deriving and using a WMMSE-based real number domain power control algorithm under multi-cell cooperationfor generating a training label close to the optimal total capacity of the system; and then inputting a multistage residual structure, training a network of a batch normalization layer, giving input channel information by outputting an activation function meeting power constraints, and predicting the transmitting power of each base station. After UcnNet training is completed, under the condition that global channel information is input, output similar to WMMSE can be generated through few calculations. An experiment simulation result shows that the high fitting capability of UcnNet is shown, the fitting efficiency can reach 97.68%, and meanwhile, the efficiency is improved by more than 100 times than that of a WMMSE iterative algorithm.
