Query: Deep Reinforcement Learning for Multi-Agent Power Control in
  Heterogeneous Networks   We consider a typical heterogeneous network (HetNet), in which multiple
access points (APs) are deployed to serve users by reusing the same spectrum
band. Since different APs and users may cause severe interference to each
other, advanced power control techniques are needed to manage the interference
and enhance the sum-rate of the whole network. Conventional power control
techniques first collect instantaneous global channel state information (CSI)
and then calculate sub-optimal solutions. Nevertheless, it is challenging to
collect instantaneous global CSI in the HetNet, in which global CSI typically
changes fast. In this paper, we exploit deep reinforcement learning (DRL) to
design a multi-agent power control algorithm in the HetNet. To be specific, by
treating each AP as an agent with a local deep neural network (DNN), we propose
a multiple-actor-shared-critic (MASC) method to train the local DNNs separately
in an online trial-and-error manner. With the proposed algorithm, each AP can
independently use the local DNN to control the transmit power with only local
observations. Simulations results show that the proposed algorithm outperforms
the conventional power control algorithms in terms of both the converged
average sum-rate and the computational complexity.
