Abstract
The disclosure provides a method and an apparatus for configuring a Cell-Specific Reference Signal (CRS). The method includes: a cell is divided into a central area and a marginal area; a CRS is divided into a central CRS, a marginal CRS and a common CRS; a value that is obtained by adding a fixed first power value to a preset reference Energy Per Resource Element (EPRE) is configured as an EPRE value of the marginal CRS; a value that is obtained by subtracting a fixed second power value from the preset reference EPRE is configured as an EPRE value of the central CRS; and the reference EPRE is configured as the EPRE value of the common CRS. The disclosure can improve an SINR of a marginal area of a cell and enhance downlink performance of a UE in the marginal area of the cell, without affecting downlink performance of a UE in a central area of the cell.
