Abstract

The invention discloses an antenna adjustment method based on reinforcement learning. The method comprises the following steps: acquiring MDT data reported by a user, and rasterizing a user cell; adjusting an antenna to align the antenna azimuth beam with the user clustering direction; calculating main cell signal coverage parameters based on the rasterized MDT data, and judging whether the antenna needs to be adjusted or not according to the main cell signal coverage parameters; on the basis of determining an antenna adjustment optimization target, constructing a state set and an action set which are respectively composed of main cell performance parameters and antenna adjustment actions, and realizing optimized adjustment of the antenna through reinforcement learning. According to the invention, the reinforcement machine learning based on the antenna adjustment optimization target is used to replace the manual calculation to realize the optimized adjustment of the antenna, the adjustment speed, efficiency and accuracy of 4G 3D-MIMO and 5G Massive MIMO antennas can be significantly improved, the 4G and 5G network performance indexes are improved, and the network experience of users is improved.
