Embodiments of the present invention provide a reference signal configuration method, a reference signal sending method, a user equipment, and a base station. According to solutions in the embodiments of the present invention, reference signal resource configuration is determined, where the reference signal resource configuration includes reference signal port configuration, reference signal subframe configuration, and reference signal configuration, and a quantity of ports configured in the reference signal port configuration is N; a reference signal is received according to the reference signal resource configuration; and measurement is performed based on the received reference signal, so as to obtain channel state information and/or signal quality information. In the embodiments of the present invention, determined network-side reference signal resource configuration includes reference signal port configuration, where a quantity of ports configured in the reference signal port configuration is N; and a quantity of supported ports may vary with different values of N. This can improve flexibility of the reference signal port configuration and help to support more antenna ports. |
