摘要

移动技术和计算系统的发展使用户设备(UE)能够管理大量的数据传输。由于目前的5G技术,毫米波频段的几种类型的无线流量可以以高数据速率传输,并且具有超可靠和小延迟的通信。5G网络依靠定向波束形成和毫米波来克服渗透过程中的传播和损耗。为了对齐最佳波束对并实现高数据速率,在5G中使用了波束搜索操作。这与多波束接收和高阶调制技术相结合,会降低终端的电池功率。在以前的4G无线移动系统中,成功地使用了不连续接收(DRX)技术来节省能源。为了降低5G多波束通信的能耗和时延,本文提出DRX波束测量技术(DRX- bm)。基于节能因素分析和延迟响应,我们将DRX-BM建模为半马尔可夫过程,以减少跟踪时间。在MATLAB中进行了仿真,以评估该模型的有效性,并避免了不必要的波束搜索时间。此外,仿真结果表明,我们提出的技术在最小延迟的情况下节省了14%的能量。

Power Saving Techniques in 5G Technology for Multiple-Beam Communications
—The evolution of mobile technology and computation systems enables User Equipment (UE) to manage tremendous amounts of data transmission. As a result of current 5G technology, several types of wireless traffic in millimeter wave bands can be transmitted at high data rates with ultra-reliable and small latency communications. The 5G networks rely on directional beamforming and mmWave uses to overcome propagation and losses during penetration. To align the best beam pairs and achieve high data rates, beam-search operations are used in 5G. This combined with multibeam reception and high-order modulation techniques deteriorates the battery power of the UE. In the previous 4G radio mobile system, Discontinuous Reception (DRX) techniques were successfully used to save energy. To reduce the energy consumption and latency of multiple-beam 5G radio communications, we will propose in this paper the DRX Beam Measurement technique (DRX-BM). Based on the power-saving factor analysis and the delayed response, we will model DRX-BM into a semi-Markov process to reduce the tracking time. Simulations in MATLAB are used to assess the effectiveness of the proposed model and avoid unnecessary time spent on beam search. Furthermore, the simulation indicates that our proposed technique makes an improvement and saves 14% on energy with a minimum delay.
