Abstract
The present invention discloses a network optimization method for a large-scale MIMO network and a base station thereof. The base station enables, according to a user minimum SINR threshold of each user in a preset cell, instantaneous spectral efficiency of the cell at a specific moment to approximate or reach a maximum value. In the present invention, a newly added user minimum SINR threshold parameter is configured, and a characteristic of a concave function is used, so that average spectral efficiency and edge spectral efficiency of each cell are simply and effectively controlled, so as to achieve an objective of coordination adjustment of network capacity and network coverage.
