Realizing Intelligence in 6G Communications: A Review

6G and beyond wireless communication are considered revolutionary generation of networks, which is able to fulfil the requirements of fully connected world. Structure of 6G communication networks is tended to be densely deployed, dynamic, extremely heterogenous with tight quality of service and because of this architecture untenability of network operation. Due to this reason, artificial intelligence (AI), machine learning (ML) and deep learning (DL) have emerged as a solution to deploy a fully intelligent 6G network. In this paper, key aspects of 6G communication networks and a review about implementation of AI, ML and DL in 6G communications is discussed. Furthermore, some future research directions in this domain are also given that will help researchers.
