摘要：

针对高速数据传输及计算所带来时延和终端设备能耗问题,提出了一种在上行链路采用等功率分配的传输方案。首先,依据增强现实(AR)业务的协作属性建立了针对AR特性的系统模型;其次,详细分析了系统帧结构,建立以最小化系统消耗总能量为优化目标的约束条件;最后,在保障延迟和功耗满足约束的条件下,建立了基于凸优化的移动边缘计算(MEC)资源优化求解数学模型,从而获得最优的通信和计算资源分配方案。与独立传输相比,该方案在最大延迟时间分别为0. 1 s和0. 15 s时的总能耗降幅均为14. 6%。仿真结果表明,在相同条件下,与基于用户独立传输的优化方案相比,考虑用户间协作传输的等功率MEC优化方案能显著减少系统消耗的总能量。
