Power controlled outage-aware optimal protocol for NOMA-assisted underlay D2D networks

Popis výsledku v původním jazyce

Underlay device-to-device (D2D) and non-orthogonal multiple access (NOMA) are two promising technologies that have potential to enhance the spectral efficiency for future wireless communication systems. This paper studies an underlay D2D-NOMA system in an uplink cellular network. Different from the previous works, we minimize the outage probability (OP) while allocating optimal power to the D2D group receivers. Specifically, a D2D power allocation (DPA) problem is formulated and a globally-optimal solution is obtained. As a special case, closed-form expressions are also derived for asymptotic OP-based DPA. Results are numerically validated, and an overall average performance improvement of at least 24% is observed over existing conventional power control schemes. © 2022 Elsevier GmbH
