Chapter 1. Candidate Technologies and Evaluation Challenges for 5G
Abstract
With several decades of booming development, mobile communications technology has penetrated into many related fields of our daily life. Led by various emerging applications, users have increasing higher requirements for wireless services, posing almost stringent requirements for the technical indicators of network. Therefore, the Fifth Generation mobile communications system (5G) emerges at a historic moment, devotes itself to open curtain of comprehensive informational era and provide excellent user experience. Recently, researches on key technologies for 5G are springing up in the industry, and the corresponding testing, evaluation and verification system need to be established and improved. This chapter will briefly introduce the features of candidate technologies for 5G, and then analyze the challenges faced by 5G evaluation system.

Chapter 2. Evolution of Testing Technology
Abstract
Testing and evaluation are indispensable links of technology and product inspection. The final birth of every new technology or product must go through strict testing and evaluating process. In the 5G era, the testing tools and evaluation methods are faced with new challenges along with the continuous development of the new 5G technologies. In the section of testing technology evolution of this chapter, we will give a brief review of the history of testing technologies, and make analysis on the development trend of the testing technology ecosystem according to the existing technologies. In the section of testing technology challenges, based on the characteristics of wireless communications technology and 5G technology, we will sort out and analyze the challenges of wireless communications testing technologies in terms of overall performance, the number of RF channels, and high throughput, etc.

Chapter 3. Channel Measurement and Modeling
Abstract
The wireless channel model is a deterministric or stochastic numerical description of physical propagation enviroments based on channel measurement or analysis and simulation on the basis of propagation theories. It provides an effective and simple means to approximately express the channel characteristics of the wireless transmission. Channel models can be used for link and system-level performance evaluation, optimization, and comparative studies on wireless communications technologies, algorithms, products and system. Channel model is of great importance to all wireless communications (including 5G mobile communication) research. This chapter focuses on the progress in 5G channel measurement and channel modeling. Section 3.1 introduces the requirements for 5G wireless channel model. Section 3.2 introduces and compares five commonly used channel modeling methods. Section 3.3 introduces the knowledge on channel measurement, channel measurement system and the currently ongoing 5G wireless channel measurement activities. Section 3.4 describes several channel parameter extraction algorithms and statistical analysis of channel parameters. Section 3.5 introduces several existing channel models. Section 3.6 gives an example to show the generating process of stochastic channel models. And the last section is the summary of this chapter.

Chapter 4. Software Simulation
Abstract
Starting from the requirements and technical indicators of 5G network system, this chapter analyzes the technical challenges in designing and realizing 5G software simulation system, and introduces the link level simulation and system simulation techniques with the focus on test evaluation methods, key technologies and applications, which provides technical reference for the design and realization of 5G network system software testing.

Chapter 5. Evaluation Test of Software and Hardware Co-simulation
Abstract
Software simulation has high scalability and flexibility. However, its authenticity and efficiency have a certain gap to the hardware simulation. This chapter will introduce the technique of co-simulation evaluation on software and hardware, so as to make up for weakness of software simulation in authenticity and efficiency. As a systematic statement, firstly, we will introduce the requirements, forms and applications of the co-simulation evaluation test with software and hardware. Hardware-In-the-Loop (HIL) simulation evaluation is an important and effective method forthenew technology test evaluation of wireless communications. Next, we will elaborate the co-simulefation evaluation test of software and hardware forthelink-level and system-level simulations, and present the real implementations of system test cases. Finally, we summarize the co-simulation test evaluation of software and hardware.

Chapter 6. 5G Hardware Test Evaluation Platform
Abstract
Co-simulation of software and hardware provides a more realistic testing and evaluation environment to some extent, improving the efficiency of test and evaluation. But it is still different from the real test environment. Therefore, a real hardware test platform and the environment are essential to the process of developing new technology. On July 15, 2016, the US government announced that 400 million US dollars will be invested to the Advanced Wireless Research Initiative (AWRI) led by National Science Foundation (NSF), which will build four city-scale experimental test platforms and deploy advanced future wireless research projects. The program will use two models: (1) 85 million US dollars will be invested through public-private partnership to deploy and establish an advanced wireless experimental test platform. Each platform will deploy software defined wireless networks in the urban area, allowing academics, entrepreneurs and wireless companies to test, evaluate and improve their technology and software algorithms in real-world environment. (2) The NSF will invest US$ 350 million to support advanced wireless communications theory and technology research. These wireless experimental test platforms and fundamental researches will support academic and business to develop and test advanced wireless communication technologies.

Chapter 7. Field Trial Network
Abstract
The ultimate goal of mobile communications technology research and development and evaluation is application. The field trial is the last and also the most important part of the technology from research to the application. During the R&D process of 5G key technology, the technological feasibility must also be verified by the field trial, providing experimental basis for standardization.
