This book presents LTE evolution towards 5G mobile communication and the
emergence of new requirements for MBB, MTC and LLC services.
As LTE technologies evolve, LTE Advanced Pro dramatically increases cell
capacity and user data rates for the MBB unicast service. Such
requirements are obtained using full-dimension MIMO, carrier aggregation
(on either licensed or unlicensed frequency bands) and dual
connectivity.
To improve the efficiency of same-content delivery to multiple users,
3GPP proposes a group communications service over LTE and defines
mission critical push-to-talk (MCPTT) for dedicated public safety
services.
Complementary low-cost and low-power modems with enhanced coverage and
massive connectivity are emerging. Thus, this book also discusses the
need for LTE to support low-rate transmission and high-latency
communication for MTC services.
