Abstract

The embodiment of the invention discloses a millimeter wave phased array beam alignment method and communication equipment. The method includes: the first device communicates with the second device through a low-frequency communication link to determine a search angle; the first device transmits a first millimeter wave signal to the second device in a direction indicated by the search angle performing a search; the first millimeter-wave signal is a high-frequency millimeter-wave signal; the first device receives feedback information sent by the second device, wherein the second device receives the feedback information in the direction indicated by the search angle sending the feedback information after receiving the first millimeter wave signal; after receiving the feedback information, the first device determines to implement millimeter wave phase control with the second device in the direction indicated by the search angle array beam alignment. This method reduces the blindness of beam search, greatly reduces the number of beam scans, and improves the efficiency of phased array beam alignment.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a millimeter wave phased array beam alignment method and communication equipment. Background technique [0002] At present, the large-scale short-range wireless communication standards mainly work in the 2.4GHz and 5GHz frequency bands, and the 60GHz millimeter wave communication technology is becoming increasingly active. Compared with the existing frequency band, 60GHz millimeter wave communication technology can realize ultra-high-speed digital wireless transmission of several gigabits per second (Gbps) between electronic devices. In the future, wireless communication equipment will be able to work in the three frequency bands of 2.4GHz / 5GHz / 60GHz. The 2.4GHz / 5GHz frequency band is used to realize lower-speed data transmission, and the 60GHz frequency band is used to realize high-speed data transmission. [0003] The 60GHz millimeter wave is one of the attenuation pea...
