Abstract

Ultra-reliable and low latency communications (URLLC) is one of the major scenarios in IMT-2020. The increase of network traffic significantly downgrades the transmission quality of the licensed spectrum and makes the strict requirements of URLLC hard to be satisfied. Thus, offloading traffic from the licensed spectrum to the unlicensed spectrum is a promising solution to cope with this challenge. This paper proposes a beam-based channel reservation mechanism to occupy the channel in the unlicensed spectrum. We also investigate the influence of hidden node problem on system performance. Numerical results validated that the proposed scheme can achieve the requirement of URLLC.
