Abstract

The present invention discloses a measurement configuration and reporting method for multi-carrier system and device thereof, and the method comprises the following steps: eNB sends RRC signaling carrying multi-carrier measurement configuration information to the terminal; said terminal measures according to said multi-carrier measurement configuration information and carries multi-carrier measurement results in measurement report message.
