%T A Random Access Protocol for Massive MIMO:   The Adaptive ACB based Collision Resolution
%U https://eprints.uet.vnu.edu.vn/eprints/id/eprint/4695/
%X mMTC (massive Machine Type   Communications) is one of the key components in beyond 5G   networks for smart manufactures and the fourth industrial   revolution. Due to the massive connectivity in mMTC, it is vital   to have an efficient random access protocol. In the paper, we   propose a new random access technique called the Adaptive   ACB (A-ACB) to minimize collisions. We show that, in terms of   successfully resolved probability, the proposed A-ACB always   outperforms the ACBPC protocol [1] and surpasses the SUCRe   protocol [2] when the number of collisions per preamble is large.   In addition, the proposed protocol achieves better fairness than   the SUCRe but less than the ACBPC. Finally, numerical results   are provided to demonstrate the effectiveness of the proposed   random access protocol.
