Measurement method, base station and terminal

Abstract

Embodiments of the present invention disclose a measurement method, a base station and a terminal. The method includes: a base station sends a switch message for a narrow bandwidth reception mode to a terminal to instruct the terminal to switch to a designated narrow bandwidth to receive information, wherein a width of the narrow bandwidth is less than a width of a system bandwidth; the base station schedules the terminal to switch to the system bandwidth to measure a downlink reference signal when channel state information of a downlink channel needs to be measured. By adopting the embodiments of the present invention, the terminal may flexibly switch between the narrow bandwidth and the system bandwidth, and a measurement for CSI of a downlink channel is realized and a power consumption of the terminal is reduced.
