摘要:

未来几代的移动网络预计将包含越来越多的天线,其复杂性和参数越来越多。为了保证网络的良好性能,必须优化这些参数。移动网络的规模使得使用人工干预或手工设计策略来优化天线参数具有挑战性。强化学习是解决这一挑战的一种有前途的技术,但现有方法通常使用局部优化来扩展到大型网络部署。我们提出了一种新的多智能体强化学习算法来全局优化移动网络配置。通过使用值分解方法,我们的算法可以从全局奖励函数中进行训练,而不是依赖于跨不同小区的网络性能的ad-hoc分解。该算法采用图神经网络架构,它可以推广到不同的网络拓扑结构,并学习协调行为。我们经验证明的天线倾斜调谐问题和联合倾斜和功率控制问题在模拟环境中的算法的性能。

英文摘要:

Future generations of mobile networks are expected to contain more and more antennas with growing complexity and more parameters. Optimizing these parameters is necessary for ensuring the good performance of the network. The scale of mobile networks makes it challenging to optimize antenna parameters using manual intervention or hand-engineered strategies. Reinforcement learning is a promising technique to address this challenge but existing methods often use local optimizations to scale to large network deployments. We propose a new multi-agent reinforcement learning algorithm to optimize mobile network configurations globally. By using a value decomposition approach, our algorithm can be trained from a global reward function instead of relying on an ad-hoc decomposition of the network performance across the different cells. The algorithm uses a graph neural network architecture which generalizes to different network topologies and learns coordination behaviors. We empirically demonstrate the performance of the algorithm on an antenna tilt tuning problem and a joint tilt and power control problem in a simulated environment.
