“…The proposed solution provides significantly higher throughput gains; declines with the increase in the number of BSs due to the higher interference levels, but the fairness index remains nearly constant. The authors of [ 21 ] study RA for an OFDMA small-cell network with prioritization of the users’ data streams. The considered system model includes a varying number of indoor small cells and users served by them, on a variable number of channels.…”

“…To better apply to UDN, [26] proposes an interference-separation clustering-based scheme to divide the massive small cells into smaller groups with different priorities, which reduces the network scale. A graphbased QoS-aware resource allocation(RA) scheme [27], [28] and a similarity UE clustering-based interference alignment scheme [29] are proposed to maximize the number of UEs while guaranteeing the QoS requirement of UEs. Moreover, the authors in [30] propose a non-cooperative game based joint base station (BS) association and power allocation (PA) scheme to optimize system throughput with satisfying the signal-to-interference-plus-noise ratio (SINR) requirements of all UEs.…”

“…Specifically, the authors in [206] study the load management problem in a multi-cell OFDMA-based network, aiming at minimizing the total load of the base stations on the shared resource blocks and determining the number of users whose demands can be concurrently satisfied. A similar problem has been studied in [207] considering OFDMA two-tier femtocell networks via proposing a joint admission control and resource management approach. The problem is formulated via the integer nonlinear programming and its solution is determined by a graph-based algorithm with polynomial computational complexity.…”
