论文摘要
在本文中，我们开发了一个框架，以优化联合用户基础站〜（BS）关联，〜子通道分配和电源控制，考虑一个启用内部元素（IBFD）的小型小细胞网络，可以最大化网络能效率（EE）。我们最大化EE（网络聚集吞吐量和功耗的比率），同时保证上行链路和下行链路的最低数据速率要求。被认为的问题属于混合成员非线性编程问题（MINLP），{\ color {black {black}的类别，因此是np-hard}。为了应对这种复杂性并在系统吞吐量和能源利用率之间取消权衡取舍，我们首先将被认为的问题重新考虑为一个多目标优化问题（MOOP），旨在同时使系统的吞吐量最大化并最大程度地减少系统的能源消耗。然后，使用$ε$ -constraint方法来解决此摩托车。为此，我们首先将二进制亚渠道和BS分配变量转换为连续的变量，而无需改变问题的可行区域，然后通过大量最小化（MM）方法近似非convex速率函数。给出了模拟结果，以证明我们提出的算法在改善网络EE方面的有效性。
In this paper, we develop a framework to maximize the network energy efficiency (EE) by optimizing joint user-base station~(BS) association,~subchannel assignment, and power control considering an in-band full-duplex (IBFD)-enabled small-cell network. We maximize EE (ratio of network aggregate throughput and power consumption) while guaranteeing a minimum data rate requirement in both the uplink and downlink. The considered problem belongs to the category of mixed-integer non-linear programming problem (MINLP), {\color{black} and thus is NP-hard}. To cope up with this complexity and to derive a trade-off between system throughput and energy utilization, we first restate the considered problem as a multi-objective optimization problem (MOOP) aiming at maximizing system's throughput and minimizing system's energy consumption, simultaneously. This MOOP is then tackled by using $ε$-constraint method. To do so, we first transform the binary subchannel and BS assignment variables into continuous ones without altering the feasible region of the problem and then approximate the non-convex rate functions through majorization-minimization (MM) approach. Simulation results are presented to demonstrate the effectiveness of our proposed algorithm in improving network's EE compared to the existing literature.~Furthermore, simulation results unveil that by employing the IBFD capability in OFDMA networks, our proposed resource allocation algorithm achieves a $69\%$ improvement in the EE as compared to the half-duplex system for practical values of residual self-interference.
