In this paper, we study the outage probability of device-to-device (D2D)-communication-
enabled cellular networks from a general threshold-based perspective. Specifically, a
mobile user equipment (TIE) transmits in D2D mode if the received signal strength (RSS)
from the nearest base station (BS) is less than a specified threshold β≥ 0; otherwise, it
connects to the nearest BS and transmits in cellular mode. The RSS-threshold-based setting
is general in the sense that by varying β from β= 0 to β=∞, the network accordingly evolves …

In this paper, the outage possibility of device-to-device (D2D)-communication with non-
orthogonal multiple access (NOMA) enabled cellular networks from a common threshold-
based perspective is studied. Particularly, this work propose NOMA signal processing
scheme of D2D transmission mode with or without help of the base station help a portable
user equipment (UE) forwarding superimposed signals in relay and direct mode. A united
framework is supplied to inspect the link outage possibility in each pair of D2D users over …
