Abstract: A multi-channel audio signal coding method includes obtaining a to-be-encoded first audio frame, pairing at least five channel signals according to a first pairing manner to obtain a first channel pair set, obtaining a first sum of correlation values of the first channel pair set, where one channel pair has one correlation value, pairing the at least five channel signals according to a second pairing manner to obtain a second channel pair set, obtaining a second sum of correlation values of the second channel pair set, determining a target pairing manner of the at least five channel signals based on the first sum of correlation values and the second sum of correlation values, and encoding the at least five channel signals based on a channel pair set corresponding to the target pairing manner, where the target pairing manner is the first pairing manner or the second pairing manner.

Abstract: In a power adjustment method for reducing energy consumption of a network system, a network management server collects a network indicator of a cell in the network system. The network management server uses the network indicator to establish a prediction model, and uses the prediction model to predict energy consumption and quality of service of the network system based on transmit power of the cell. The network management server then adjusts the transmit power of the cell based on the prediction model to meet a constraint condition of the quality of service and an energy consumption optimization objective of the network system.
