Abstract: A method for terminal measurement and configuration, a terminal and a base station are provided. The method for terminal measurement and configuration applied to the terminal includes: detecting a state parameter of the terminal; and obtaining measurement configuration information configured based on the state parameter. The method for terminal measurement and configuration applied to the base station includes: obtaining a state parameter of a terminal; and feeding back measurement configuration information to the terminal based on the state parameter. Therefore, the measurement configuration information configured based on the state parameter of the terminal is obtained, and more control optimization on the behavior of the terminal can be performed according to the measurement configuration information. Thus, power consumption of the terminal is saved in a communication system.
