**The evolution of wireless*networks from 4G to 5G has to face several fundamental challenges, including*higher data rates, excellent end-to-end performance and user-coverage in*hot-spots and crowded areas with lower latency, energy consumption and cost per*information transfer. To address these challenges, 5G system prefers a*multi-tier architecture consisting of macrocells, different types of licensed*small cells, relays, and device-to-device (D2D) networks to serve users with*different quality-of-service (QoS) requirements in a spectrum and*energy-efficient manner.***** *****Radio resource management (RRM)*will play a key role in multi-tier or heterogeneous 5G networks. The*traditional 4G RRM schemes, such as channel allocation, power control, cell*association and load balancing, may not be efficient in 5G environment, due to*the emerging cutting edge technologies, e.g., millimeter waves (mmWave),*massive MIMO, etc.***** *****The deployment and operation of*5G HetNets will be an extremely complicated task because of the growing scale*and complexity of information systems. Self-organizing and optimization,*therefore, have been recognized as a critical part of 5G ensembles, as human*based network configuration is proven to be labor-intensive, costly, and*error-prone. This project considers the next generation HetNets, which consist*of a mixture of network tiers, transmit powers and backhaul connections. We*will develop a novel scheme of adaptive self organization network (SON) by*integrating cognitive radio (CR) with inter-cell interference coordination*(ICIC). Our proposed adaptive SON system will also take into account the*spatial relationship of different network element, so that mmWave and massive*MIMO technology can well achieve the spectrum efficiency that 5G system requires.****

** 无线 * 网络从4G向5G的演进必须面对几个基本挑战，包括 * 更高的数据速率、出色的端到端性能、* 热点和拥挤区域的用户覆盖以及更低的延迟、能耗和每 * 信息传输成本。为了应对这些挑战，5G系统更倾向于采用由宏小区、不同类型的授权小小区、中继和设备到设备（D2D）网络组成的多层架构，以频谱和节能方式为具有不同服务质量（QoS）要求的用户提供服务。* 无线电资源管理（RRM）* 将在多层或异构5G网络中发挥关键作用。传统的4G RRM方案，例如信道分配、功率控制、小区关联和负载平衡，在5G环境中可能不是有效的，这是由于新兴的尖端技术，例如，毫米波（mmWave）、* 大规模MIMO等 * * 由于信息系统的规模 * 和复杂性不断增长，*5G HetNet的部署和运营将是一项极其复杂的任务。因此，自组织和优化已被认为是5G集成的关键部分，因为基于人工的网络配置已被证明是劳动密集型的，成本高昂且容易出错。该项目考虑了下一代HetNet，它由网络层，发射功率和回程连接的混合物组成。我们将开发一种新的方案，自适应自组织网络（SON）的认知无线电（CR）与小区间干扰协调（ICIC）。我们提出的自适应SON系统还将考虑不同网络元素的空间关系，因此mmWave和大规模MIMO技术可以很好地实现5G系统所需的频谱效率。
