Ultra-Reliable Low-Latency Control Signaling in a Factory Environment

The recently released 3GPP Fifth Generation New Radio (5G NR), does not always meet ultra-reliable low-latency communication (URLLC) requirements that are becoming more necessary as massive machine-type communications (mMTC) evolve. Sixth Generation communications (6G) will implement URLLC solutions capable of satisfying a large spectrum of latency and reliability requirements. Currently, control channels implemented in 5G NR suffer from low spectral efficiency, hence, in a high traffic network may fail to satisfy the URLLC requirements. Cyclic prefixed direct sequence spread spectrum (CP-DSSS) is an LTE compatible waveform that has recently been proposed as a more efficient signaling that better satisfies the needs of URLLC. In this article, CP-DSSS is further developed and its usefulness to a 3GPP-proposed factory floor is presented through a system-level simulation.
