Abstract

The embodiment of invention discloses a millimeter wave phased-array wave beam aligning method and communication equipment. The millimeter wave phased-array wave beam aligning method comprises the following steps that: first equipment and second equipment communicate through a low-frequency stage communication link to determine a search angle; the first equipment transmits a first millimeter wave signal in the indicated direction of the search angle to search the second equipment; the first millimeter wave signal is taken as a high-frequency millimeter wave signal; the first equipment receives the feedback information transmitted by the second equipment, and the second equipment transmits the feedback information after receiving the first millimeter wave signal in the indicated direction of the search angle; and the first equipment determines to realize millimeter wave phased-array wave beam alignment in the indicated direction of the search angle with the second equipment after receiving the feedback information. The millimeter wave phased-array wave beam aligning method disclosed by the embodiment of the invention reduces the blindness of wave beam search, greatly decreases the wave beam scanning times and improves the phased-array wave beam aligning efficiency.

Description

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