Embodiment Construction
[0080] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0081] In communication scenarios with large-scale antennas, beamforming design is crucial. The present invention considers that in a large-scale Multiple-Input and Multiple-Output (MIMO) heterogeneous network, under the constraints of the user's Quality of Service (QoS), a new system is proposed with the goal of maximizing system energy efficiency. A low-latency, energy-efficient cooperative beamforming algorithm.
[0082] Although the existing beamforming algorithms widely used in massive MIMO systems can achieve better system performance, the calculation delay increases significantly with the increase of the number of antennas, which is not suitable for massive MIMO systems. At the same time, in order to improve the practicability, although the...
