4G：LTE⁄LTE-Advanced for Mobile Broadband(2nd Edition)

This book describes LTE, developed in 3GPP (Third Generation Partnership Project) and providing true 4G broadband mobile access, starting from the first version in release 8 and through the continuing evolution to release 11, the latest version of LTE. Releases 10 and 11, also known as LTE-Advanced, is of particular interest as it is the major technology approved by the ITU as fulfilling the IMT-Advanced requirements. The description in this book is based on LTE release 11 and thus provides a complete description of the LTE-Advanced radio access from the bottom up.
