22775 针对密集组网场景中业务不确定性引起的基站休眠周期难以确定的问题，该文提出一种基于部分可测马尔可夫决策过程(Partially Observed Markov Decision Process, POMDP)业务感知的微基站休眠时长确定策略。 In order to solve the problem that the sleeping cycles are difficult to be determined duo to the traffic uncertainty in dense network scenarios, this paper proposes a Micro base station sleeping cycle determination strategy which based on the Partially Observed Markov Decision Process (POMDP) traffic-aware.
22776 该策略将周期分为长周期和短周期，每个周期由轻度和深度两个阶段构成。 In this strategy, the sleeping cycle is divided into long cycle and short cycle, and each cycle consists of deep and light stage.
22777 通过 POMDP 感知到达基站的业务状态，动态调整周期时长，进而选取适合当前周期的时长。 Based on the POMDP traffic-aware, it can dynamically adjusting the cycle and determine the proper length of cycle.
22778 仿真结果表明，该策略可以根据业务感知提前确定微基站关断时长，与基于业务门限值的基站关断机制相比节能效果更好。 Both the analytical and simulation results show that compare with sleeping strategy based on the traffic threshold, the base station sleeping strategy based on traffic awareness can effectively reduce the energy consumption of the micro base stations in the dense network by adjusting the sleeping time of the micro base stations in real time.
22779 绕射非局部边界条件是基于有限差分法求解抛物方程时使用的一种透明边界条件。 Diffraction nonlocal boundary condition is one kind of the transparent boundary condition which is used in the Finite Difference (FD) Parabolic Equation (PE).
22780 它的最大优点是只用一层网格就能很好完成波地吸收，而缺点是由于涉及到卷积积分的计算，因此计算速度低。 The biggest advantage of the diffraction nonlocal boundary condition is that it can absorb the wave completely by using of one layer of grid. However, the computation speed is low because of the time consuming spatial convolution integrals.
22781 针对此问题，该文首先引入可以加快其计算速度的递归卷积法和矢量拟合法。 To solve this problem, the recursive convolution and vector fitting method are introduced to accelerate the computational speed.
22782 这里把结合了这两种数值计算方法的绕射非局部边界条件称为改进型绕射非局部边界条件。 The diffraction nonlocal boundary combined with these two kinds of methods is called as improved diffraction nonlocal boundary condition.
22783 在此基础之上，提出将这种改进型的绕射非局部边界条件应用到 3 维抛物方程(3DPE)分解模型中。 Based on the improved nonlocal boundary condition, it is applied to Three-Dimensional Parabolic Equation (3DPE) decomposed model.
22784 最后通过数值计算，证明了改性型绕射非局部边界条件 3DPE 分解模型在计算精度和计算速度方面的优势。 Numeric computation results demonstrate the computational accuracy and the speed of this three-dimensional parabolic equation decomposed model combined with the improved diffraction nonlocal boundary condition.
