Abstract
According to a resource configuration method, user equipment, and a base station that are provided in embodiments of the present invention and relate to the communications field, reference signals used for measurement and overheads of corresponding measurement and feedback are reduced. A specific solution is as follows: A base station sends M reference signals to UE in N time units in a time unit set, where the reference signal is used by the UE to perform channel quality measurement, and each reference signal in the M reference signals is corresponding to one piece of precoding matrix information; receives channel quality indication information sent by the UE.
