METHOD AND APPARATUS FOR CONFIGURING CELL-SPECIFIC REFERENCE SIGNAL

摘要

Disclosed are a method and apparatus for configuring a cell-specific reference signal (CRS). The method comprises: dividing a cell into a central area and a marginal area; dividing the CRS into a central CRS, a marginal CRS and a public CRS; raising a fixed first power value on the basis of a preset reference energy per resource element (EPRE), and configuring the first power value as the EPRE value of the marginal CRS; reducing a fixed second power value on the basis of the preset reference EPRE, and configuring the second power value as the EPRE value of the central CRS; and configuring the reference EPRE as the EPRE value of the public CRS. The present invention can improve the SINR of the marginal area of the cell and enhance the downlink performance of the UE in the marginal area of the cell without affecting the downlink performance of a UE in the central area of the cell.
