The disclosure proposes a dynamic beamforming method and related apparatuses using the same method. According one of the exemplary embodiments, the proposed dynamic beamforming method is applicable to a base station and includes not limited to transmitting a first reference signal; transmitting a first configuration message comprising a first oversampling rate of a first dimension and a first oversampling rate of a second dimension; receiving a first information feedback of the first reference signal based on the first oversampling rate of the first dimension and the first oversampling rate of the second dimension in response to transmitting the first configuration message; and transmitting a second configuration message comprising a second oversampling rate of the first dimension and a second oversampling rate of the second dimension after receiving the first information feedback of the first reference signal.
