Claim of US Patent No. 10,342,030

1. A network optimization method for a large-scale MIMO network, comprising the following step:after obtaining a user minimum SINR threshold in a preset cell, a base station selects a specific user, and estimates a SINR estimate of the specific user; the SINR estimate of the specific user is calculated according to the following formula:

wherein T is a total transmitting power of the base station, N is a noise power, P is second-stage precoding, I is inter-cell interference and intra-cell interference, and a rank of PPH is a quantity K of scheduled users:
the base station schedules the users according to the user minimum SINR threshold, to have a cell-system spectral efficiency of the preset cell at a specific moment to approximate or reach a maximum value.
