Embodiments of the present invention disclose a measurement method, user equipment, a base station, and a wireless communications system, where the method includes: determining, according to transmit bandwidth and transmit time of a new carrier type cell-specific reference signal in a cell of the first base station and the transmit bandwidth and the transmit time of the new carrier type cell-specific reference signal in the cell of the second base station, measurement bandwidth and measurement time corresponding to a cell in which user equipment is located; and transmitting measurement configuration information including the measurement bandwidth and the measurement time to the user equipment. The first base station may acquire the transmit bandwidth and the transmit time, and deliver, to UE, measurement configuration information including two pieces of information, namely, measurement bandwidth and measurement time. Therefore, a solution for performing effective measurement in a new carrier type is provided.
