时延中断约束下机器类通信中的节能自适应传输

Energy-Efficient Adaptive Transmission in Machine Type Communications with Delay-Outage Constraints

Linlin Zou, Yanzhao Hou, Xiaofeng Tao, Qimei Cui, Xueqing Huang

摘要:

在本文中,我们提出了一种新的自适应传输策略,以提高无线点对点传输系统中具有服务质量(QoS)要求的能量效率,延迟中断概率考虑。发射机被调度使用具有更好的系数的信道,并且当信道遭受深衰落时被强制进入静默状态。所提出的策略可以很容易地实现,通过应用双模式电路,并适用于大规模机器类型通信(MTC)的情况。为了提高EE,我们制定了一个EE最大化问题,它有一个单一的最优条件下的宽松的QoS约束。我们还表明,最大化问题可以有效地解决二分搜索算法。仿真结果表明,我们提出的策略可以获得显着的EE收益,从而证实了我们的理论分析。

英文摘要:

In this paper, we propose a novel Adaptive Transmission Strategy to improve energy efficiency~(EE) in a wireless point-to-point transmission system with Quality of Service~(QoS) requirement, i.e., delay-outage probability considered. The transmitter is scheduled to use the channel that has better coefficients, and is forced into silent state when the channel suffers deep fading. The proposed strategy can be easily implemented by applying two-mode circuitry and is suitable for massive machine type communications (MTC) scenarios. In order to enhance EE, we formulate an EE maximization problem, which has a single optimum under a loose QoS constraint. We also show that the maximization problem can be solved efficiently by a binary search algorithm. Simulations demonstrate that our proposed strategy can obtain significant EE gains, hence confirming our theoretical analysis.
