There has been a growing interest in developing data-driven, and particular deep neural network (DNN) based methods for modern communication tasks. For few popular tasks such as power control, beamforming, MIMO detection, these achieve state-of-the-art performance while requiring less computational efforts, resources acquiring channel state information (CSI), etc. However, it is often challenging approaches to learn dynamic environment.
