Abstract Aiming for ultra-reliable low-latency wireless communications required
in industrial internet of things (IIoT) applications, this paper studies a simple cognitive radio non-orthogonal multiple access (CR-NOMA) downlink system. This
system consists of two secondary users (SUs) dynamically interfered by the primary user (PU), and its performance is characterized by the outage probability of
the SU communications. This outage probability is calculated under two conditions where, a) the transmission of PU starts after the channel state information
(CSI) is acquired, so the base station (BS) is oblivious of the interference, and
b) when the BS is aware… More >
