The invention discloses beamforming equipment and a beamforming method. The beamforming equipment comprises a radio frequency module and a main control module, wherein the radio frequency module is connected with M vibration sources and N target terminals of a base station; the control end of the main control module is connected with the controlled end of the radio frequency module; the radio frequency module comprises a first phase shifting units, b second phase shifting units and a radio frequency cable; each first phase shifting unit is provided with M / a input ports and b output ports; each second phase shifting unit is provided with a input ports and N / b output ports; each output port of each first phase shifting unit is connected with one input port of each second phase shifting unit; the first phase shifting units and the second phase shifting units are connected with the main control module; and the main control module is used for determining a horizontal adjustment phase and a vertical adjustment phase according to the received target beam angle, sending the horizontal adjustment phase to the first phase shifting units and sending the vertical adjustment phase to the second phase shifting units. According to the invention, the problems of complex construction and high cost of a base station test environment can be solved.
Description
technical field [0001] The invention relates to the technical field of wireless communication base station and terminal testing, in particular to a beam forming device and a beam forming method. Background technique [0002] The wireless communication base station has developed from 2 antennas to 8 antennas, and then to the current 64 antennas, or even 128 antennas. Wireless communication base station Massive MIMO (ultra-large-scale multiple-input multiple-output) is the core technology of 5G. In order to simulate and verify the performance of beamforming technology, a test solution that can realize ultra-large-scale multiple-input multiple-output, beamforming and beam tracking is required. [0003] With the widespread deployment of LTE+ (Long Term Evolution, long-term evolution) and the gradual promotion of 5G, the industry has gradually solidified the test cases for base station equipment and terminal equipment, and the test volume has gradually increased. It is particular...
