[0025] The implementation process of the application of the present invention in the LTE-R system frequency planning method based on distributed base stations will be described in detail in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.
[0026] The present invention is a frequency planning method applied to an LTE-R system based on a distributed base station. The method is suitable for a railway-specific broadband mobile communication system deployed along a railway line. The method selects a key area point along the railway line as a cell center. The method comprises the steps of:
[0027] Step 1: Select multiple key regional points along the railway line as first-level hotspots;
[0028] Step 2: The first-level hotspot is used as the center point of each cell, and the coverage of the first-level hotspot cell is determined according...
