[0023] The content of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] Such as figure 1 As shown, an LTE system multi-input multi-output mode switching method includes the following steps:
[0025] S1 receives the CQI parameter value and the RI parameter value reported by the user equipment;
[0026] S2 Counts the number of times the CQI parameter value continuously reported by the user equipment is continuously greater than the channel quality indicator threshold value, the number of times continuously less than or equal to the channel quality indicator threshold value, and the RI parameter value continuously reported by the user equipment in the preset period The number of times greater than 1, and the number of consecutive times equal to 1;
[0027] S3 switches the MIMO mode between the LTE base station and the user equipment according to the statistical result.
[0028] After the user equipment accesses the LTE system, th...
