Disclosed are a beam processing method, an initial beam discovery method, a base station, and a terminal. At a base station side, different beams of different transceiver links are processed to obtain a beam cell ID; and a synchronizing signal and a reference signal are generated by utilizing the beam cell ID, synchronizing signals or reference signals of different beams being staggered in position over a time frequency resource. The reference signals and synchronizing signals of different beams are staggered over a time frequency domain resource, thus avoiding mutual interference between beam scanning or multi-beam simultaneous transmitting. At a terminal side, the terminal measures the synchronizing signals and reference signals of different beams respectively, and compares the synchronizing signals and the reference signals with preset corresponding thresholds, and if the signals meet all threshold requirements, it is regarded that a physical cell ID and a beam ID can be identified by the terminal.
