AN OPTIMIZATION APPROACH OF BLOCK LENGTH FOR URLLC-5G

Abstract

Fifth Generation wireless networks (5G) have been one of the priority areas
studied by scientists in recent years because of their benefits in many fields of life. The
requirements in modern communication systems are to increase performance in the
process of transmitting and receiving information. Extremely reliable low-latency
communication (URLLC) is one of the three main tasks in 5G. According to 3GPP, URLLC
has 99.999% transmission accuracy with a latency of less than 1ms which is the goal
of many current studies. In this article, we analyze and evaluate some of the factors
that affect the latency and probability of errors that can be achieved in the uplink and
downlink of Massive MIMO in the finite block in URLLC. In addition, this study presents
a solution that offers a suitable length in the packet design of large MIMO systems that
support the high-reliability targets required in URLLC.
