摘要

针对LTE-A上行蜂窝链路与终端直通链路间的同频干扰问题，提出一种联合资源分配方案来最大化D2D链路总能效。上述问题可分解为功率控制和信道分配2个子问题。其中，功率控制子问题可借助Dinkelbach法和拉格朗日对偶得到最优解；信道分配子问题等价于集装箱问题，属于NP难问题，因此，提出一种启发式算法，实现算法性能与复杂度之间的折中。仿真结果表明所提联合资源分配方案优于单一资源优化方案，此外，其具有多项式复杂度且其性能接近理论最优解。

Abstract

To cope with the co-channel interference between cellular links and device-to-device (D2D) links concurrently transmitting with the long term evolution-advanced (LTE-A) uplink spectrum

a joint resource allocation scheme was pro-posed to maximize the global energy efficiency of D2D links.The above problem can be decomposed into the power control subproblem and the channel assignment subproblem.Specifically

the power control subproblem can be optimally solved with the help of Dinkelbach method and Lagrange duality.Based on the above results

the channel assignment subproblem turns out to be the set packing problem which was generally NP-hard problem

Therefore

a heuristic algo-rithm was further devised to achieve a tradeoff between performance and complexity.Simulations show that the proposed joint resource allocation scheme outperforms the ones where only single resource variable is optimized

and it achieves the polynomial-time complexity at only minor performance loss when compared to the global optimum.
