Abstract
mMTC (massive Machine Type Communications) is one of the key components in beyond 5G networks for smart manufacturing and the Fourth Industrial Revolution. Due to the massive connectivity in mMTC, it is vital to have an efficient random access (RA) 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 while surpassing the SUCRe protocol 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.
mMTC(大规模机器类型通信)是智能制造和第四次工业革命的超5G网络的关键组成部分之一。由于mMTC中存在大量的连接,因此高效的随机访问(RA)协议至关重要。在本文中,我们提出了一种新的随机存取技术,称为自适应ACB (a -ACB),以减少碰撞。结果表明,当每个前导的碰撞次数较大时,所提出的A-ACB在成功解析概率方面始终优于ACBPC协议,并优于SUCRe协议。此外,该协议的公平性优于SUCRe协议,但低于ACBPC协议。最后给出了数值结果,验证了所提随机接入协议的有效性。
