5G System Design An End to End Perspective

This book presents a detailed pedagogical description of the 5G commercial wireless communication system design, from an end to end perspective, by those that were intimate with its development. The exposition only assumes that the reader is passingly familiar with LTE and builds upon that knowledge. By comparing and contrasting NR with LTE, it allows for quick mastering of 5G. As such it gives concise and highly accessible description of the key technologies in the 5G physical layer, radio access network layer protocols and procedures, how the 5G core and EPC is integrated into the radio access network, how virtualization, slicing and edge computer will fundamentally change the way we interact with the network, as well as 5G spectrum issues.

The 2nd edition of this book significantly enhances and updates the first edition by adding 5G security and Release-16 developments. Loosely speaking, 5G Release-15 can be characterized as being optimized for the cellular carrier eMBB service while 5G Release-16 is the beginning of the optimization of 5G for the vertical industries. It mainly focused on the support of the vehicular vertical and Industrial Internet of Things. As such, we have significantly altered the first edition to cover the key features standardized in Release-16 including: URLLC, V2X, IIoT, enhanced MIMO, unlicensed access, positioning, power savings and IAB. On the network side, detailed discussion covers NR security as well as the newly standardized access traffic steering, non 3GPP access switching and splitting features, non 3GPP access network support and private networks.

Engineers, computer scientists and professionals from those with a passing knowledge of 4G LTE to experts in the field will find this book to be a valuable asset. They will gain a comprehensive understanding of the end to end 5G commercial wireless system. Advanced-level students and researchers studying and working in communication engineering, who want to gain an understanding of the 5G system (as well as methodologies to evaluate features and technologies intended to supplement 5G) will also find this book to be a valuable resource.

Wan Lei is a Huawei fellow and currently head of Wireless Standard, Huawei Tech. Co. Ltd. She led the next generation wireless research and 3GPP 4G&5G standardization work in Huawei since 2008. Before then she was a principle engineer in Ericsson Research since 2001. Her main focus areas are network topology and air-interface evolution. She is known as the expert on network topology, system-level evaluation methodology and FDD/TDD convergence in the industry. She is the initiator of 4.5G and 5G DL/UL decoupling with LTE coexistence and one of the main contributors to 3GPP 5G standardization. In the past, she led TDD/FDD frame structure merging, CoMP, LTE-Hi (3GPP R12 small cell enhancement), LTE-V2X and U-LTE (unlicensed LTE) research and standardization. She is also the inventor of the physical layer MI quality model that is widely used in the system level simulation of telecommunication systems, such a model was adopted by 3GPP, 3GPP2, WiMAX as the link to system interface for system evaluation. She has a long experience in the wireless communication industry, with the background of WCDMA, TD-SCDMA, WiMAX, LTE and LTE-Advanced. Her research interest covers spectrum and regulation, duplex evolution, network topology evolution, air interface design specifically for traffic adaptive and interference coordination solution, evaluation methodology and autonomous driving.
