Reference signal configuration method, base station, user equipment, and system

Abstract

An embodiment of the present invention provides a reference signal configuration method. The method includes: obtaining, by the base station, a first time-domain location of a reference signal of a first cell, and mapping the reference signal of the first cell to one or more resource elements based on the first time-domain location, where there is an offset between the first time-domain location and a second time-domain location of a reference signal of a second cell, the first cell is a cell in which the base station is located, and a service area of the second cell is different from that of the first cell; and sending, by the base station, the reference signal of the first cell. According to the embodiment, mutual interference of reference signal transmission in cells can be avoided, and signal transmission efficiency and signal transmission quality can be improved.
