Wireless communication method and wireless communication apparatus

An electronic equipment for a first communication apparatus of a wireless communication system, comprising:

• a number of antenna sub-arrays, each sub-array being a planar antenna array, each column or row in the sub-array corresponding to one input terminal;
• a plurality of sets of first direction phase shifters, wherein the first direction phase shifters in each set are disposed between input terminals of the corresponding sub-arrays and a radio frequency chain,
• wherein each set of the plurality of sets of first direction phase shifters is configured to adjust a first direction angle of an antenna beam for transmitting a corresponding radio frequency chain signal in a first direction in accordance with a first control signal,
• wherein each sub-array is configured to transmit antenna beams in a second direction with a different second direction angle, the first direction and the second direction being orthogonal to each other, and
• wherein each antenna in the sub-array is connected to a second direction phase shifter, and the second direction phase shifter is configured to adjust the second direction angle of the antenna beam in the second direction according to a second control signal wherein the second direction phase shifter has a lower precision than the first direction phase shifter.
