Numerous wearable technology companies have recently developed several head‐mounted display (HMD) products for virtual reality (VR) services. 5G wireless networks aim at providing high‐quality 3D multimedia services such as VR, augmented reality, and mixed reality. In this study, we examine the application of millimeter‐wave (mmWave) technology to realize low‐latency wireless communication between an HMD and its content server. However, the propagation characteristics of mmWave present several challenges such as the deafness, blockage, and beam alignment problems, and interference among content servers. In this study, we focus on an environment that provides VR services in the mmWave band and introduce existing techniques for addressing such challenges. In addition, we employ a commercialized IEEE 802.11ad VR dongle to measure the actual data rate of an mmWave VR application and identify the degree to which the performance deteriorates when the above problems occur. Finally, we verify the feasibility of the proposed solutions through a simulation of several VR scenarios in the mmWave band.

仿真和测量：用于mmWave虚拟现实的触觉Internet应用程序的可行性研究

许多可穿戴技术公司最近都开发了几种用于虚拟现实（VR）服务的头戴式显示器（HMD）产品。5G无线网络旨在提供高质量的3D多媒体服务，例如VR，增强现实和混合现实。在本研究中，我们研究了毫米波（mmWave）技术在实现HMD及其内容服务器之间的低延迟无线通信中的应用。但是，mmWave的传播特性带来了一些挑战，例如耳聋，阻塞和光束对准问题，以及内容服务器之间的干扰。在这项研究中，我们专注于在mmWave频段提供VR服务的环境，并介绍了应对此类挑战的现有技术。此外，我们采用了商业化的IEEE 802。11ad VR加密狗可测量mmWave VR应用程序的实际数据速率，并确定出现上述问题时性能下降的程度。最后，我们通过在mmWave波段中对几种VR场景进行仿真，验证了所提出解决方案的可行性。
