The invention discloses a millimeter wave integrated communication system beam alignment method compatible with a C waveband. The method mainly solves the problem that adaptive beam alignment cannot be carried out in the prior art, and adopts the scheme that a base station determines an initial range of a user position by utilizing a C waveband, generates a beam scanning detection signal to carryout time-frequency resource allocation, and obtains a detection frame for millimeter wave beam scanning; the base station scans the millimeter wave beams in the initial range of the user position, andthe user measures the received signal power; the user selects an optimal sending beam and an optimal receiving beam according to the received signal power; the user feeds back the optimal sending beam to the base station; the base station adjusts the current sending beam into the optimal sending beam according to the optimal sending beam; and the user adjusts the current receiving wave beam intothe optimal receiving wave
