Modified Fractional Frequency Reuse Scheme for Non-orthogonal Multiple Access Networks

Device to Device Hybridization in 5G and Beyond: A Literature Review

“…To ensure effective mode selection and successful communication in D2D pair in either microwave or mmWave, it is vital that the interference caused by and suffered by the D2D equipment is mitigated efficiently. Some of the research focused on hybrid D2D interference management have put forward mechanisms such as Fractional Frequency Reuse (FFR) technique (Eslami, Mirjalily, & Davidson, 2020;Kim et al, 2018;Ningombam, et al, 2017) or a variant of FFR (Tabassum et al, 2020). Future network will have to coexist with microWave and mmWave band infrastructure side-by-side thereby necessitating the need for developing mechanisms that can accommodate seamless transitioning between both bands.…”

“…The authors report that the proposed strategy solves admission, power control problems optimally, including matching subproblems, by using heuristic suboptimal algorithm (Stern, Dreiman, & Valenzano, 2019) to allocate free sub-channels. The solution for interference is based entirely on a Modified Fractional Frequency Reuse scheme (Tabassum, Islam, & Kaiser, 2020) proffered by the authors, which is subject to minimum sum rate and transmission power constraints.
