论文摘要
在本文中，我们提出了用于多用户多重输入和多重输出〜（MU-MIMO）蜂窝通信系统的自适应技术，以解决与异构延迟感知流量的能源有效通信问题。为了最大程度地减少MU-MIMO的总传输功率，我们研究了传输功率与M-ary正交幅度幅度调节〜（MQAM）星座大小（MQAM）恒定的尺寸，并根据最小平均正方形误差〜（MMSE）接收器获得每个传输流的能源有效调节。我们提出了一种自适应传输策略，这是MU-MIMO和MU-SIMO之间的切换，我们提出了一种自适应传输策略，我们提出了一种自适应传输策略，这是整个功耗模型和异质延迟感知服务之间的内在关系。模拟表明，为了最大程度地提高能源效率并同时考虑用户的延迟质量（QoS），用户应适应每个流以及传输模式的星座大小。
In this paper, we propose adaptive techniques for multi-user multiple input and multiple output~(MU-MIMO) cellular communication systems, to solve the problem of energy efficient communications with heterogeneous delay-aware traffic. In order to minimize the total transmission power of the MU-MIMO, we investigate the relationship between the transmission power and the M-ary quadrature amplitude modulation~(MQAM) constellation size and get the energy efficient modulation for each transmission stream based on the minimum mean square error~(MMSE) receiver.Since the total power consumption is different for MU-MIMO and multi-user single input and multiple output~(MU-SIMO), by exploiting the intrinsic relationship among the total power consumption model, and heterogeneous delay-aware services, we propose an adaptive transmission strategy, which is a switching between MU-MIMO and MU-SIMO. Simulations show that in order to maximize the energy efficiency and consider different Quality of Service (QoS) of delay for the users simultaneously, the users should adaptively choose the constellation size for each stream as well as the transmission mode.
