<p>Disclosed in an embodiment of the present invention are a millimeter wave phased-array wave beam alignment method and communication device, the method comprising: a first device communicates with a second device via a low frequency range communication link to determine a search angle; the first device transmits a first millimeter wave signal in the direction indicated by the search angle to search the second device, the first millimeter wave signal being a high frequency millimeter wave signal; the first device receives feedback information transmitted by the second device, the feedback information being transmitted by the second device after receiving the first millimeter wave signal in the direction indicated by the search angle; and after receiving the feedback information, the first device determines to realize millimeter wave phased-array wave beam alignment with the second device in the direction indicated by the search angle. The method reduces wave beam search blindness, and greatly reduces wave beam scan times, thus improving phased-array wave beam alignment efficiency.</p> |
