Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a differential beamforming based random access method, base station, and user equipment, wherein the differential beamforming based random access method comprises, by a base station: receiving a preamble sequence from a first terminal in a differential beamforming receiving mode; determining a base station beam direction angular deviation based on the preamble sequence; and adjusting a base station beam according to the base station beam direction angular deviation, and transmitting a random access response signal to the first terminal through the adjusted base station beam. In the present disclosure, by detecting a base station beam direction angular deviation in a differential beamforming receiving mode, a base station receiving beam can be adjusted to an optimal beam faster than a beam polling way of the prior art, thereby improving the performance of a random access procedure.
