摘要

由于具备免许可、强方向性、高系统容量和吉比特的高传输速率等优势，60 GHz频段被列为5G新空口（new radio，NR）的候选频段之一。在5G超密集组网场景中，网络节点之间距离的降低引起的节点开关转换的随机性会导致严重的多址干扰、资源失配问题。对此，基于跨层协同设计的思想，提出了一种基于公平性的资源调度策略，在基于TH-PAM（time hopping pulse amplitude modulation）的60 GHz脉冲无线通信系统中对该策略的多址接入性能进行仿真分析。仿真结果表明，相比采用纯物理层优化算法的系统，采用该策略的多址接入系统表现出更强的公平性、更低的系统误码率，但需要额外增加发射功率来满足同等通信系统覆盖范围的要求，即在系统的能量与公平性之间存在一定的折中，可用于指导实际通信系统的构架与布设。

Abstract

Due to the advantages of license-free

strong directionality

high system capacity

and high transmission rate of Gbit/s

60 GHz band is listed as one of the candidate bands for new radios (new radio).In 5G ultra-dense networking scenario

the randomness of node switching caused by the decrease of the distance between network nodes may cause severe multiple access interference and resource mismatch problems.In this regard

based on the concept of cross-layer collaborative design

a resource scheduling strategy based on fairness was proposed.The multiple access performance of the strategy was simulated in a 60 GHz pulsed wireless communication system based on TH-PAM (time hopping pulse amplitude modulation).Simulation results show that compared with the system with pure physical layer optimization algorithm

the multiple access system which adopts this strategy shows stronger fairness and lower system error rate

but it needs increase the transmission power to meet the requirements of the coverage of the equivalent communication system.That is

there is a certain trade-off between the energy and fairness of the system

which can be used to guide the structure and deployment of the actual communication system.
