NG-RAN and 5G-NR describes the deployment of 5G NSA (non standalone 5G) and 5G-SA (standalone 5G). 5G-NSA deals with radio access entities. For the 5G-NSA mode, dual MR DC connectivity is based on radio measurements, allowing the master 4G base station MeNB to add or remove a secondary 5G node SgNB.This book describes the architecture of the NG radio access network and the 5G-NR radio interface according to the 3GPP (3rd Generation Partnership Project) specifications. The overall a...

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 ...

This publication characterizes the environmental burden of disease in the United Arab Emirates (UAE), measured by the excess number of deaths and illnesses in the population due to exposure to environmental hazards. The robust methods used in this risk analysis can be applied to any country or region. This publication documents the systematic, multi-step process used to identify environmental priorities and the detailed methods used to quantify the disease burden attributable to each risk....
