  1. 6. A Graph Attention plus Reinforcement Learning Method for Antenna Tilt Optimization

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tengfei Ma; [2021]
    Keywords : Graph Attention; Reinforcement Learning; Antenna Tilt Optimization; 5G; Attention Mechanism; Graph; DQN; Back- Propagation; Gradient Descent;

    Abstract : Remote Electrical Tilt optimization is an effective method to obtain the optimal Key Performance Indicators (KPIs) by remotely controlling the base station antenna’s vertical tilt. To improve the KPIs aims to improve antennas’ cooperation effect since KPIs measure the quality of cooperation between the antenna to be optimized and its neighbor antennas. READ MORE

    Abstract : In telecom networks adjusting the tilt of antennas in an optimal manner, the so called remote electrical tilt (RET) optimization, is a method to ensure quality of service (QoS) for network users. Tilt adjustments made during operations in real-world networks are usually executed through a suboptimal policy, and a significant amount of data is collected during the execution of such policy.

  5. 10. Self-optimization of Antenna Tilt in Mobile Networks

    University essay from KTH/Kommunikationssystem, CoS; KTH/KTH Center för Trådlösa System, Wireless@kth

    Author : Vlad-Ioan Bratu; [2012]
    Keywords : ;

    Abstract : The increased complexity of mobile networks, the need to deliver high data rate services and the variation of mobile traffic put a high burden on operation and maintenance in terms of extra workload and additional costs . New approaches to network optimization and management should be taken into account to increase network performance and reduce operational costs. READ MORE
