EXECUTIVE SUMMARY 3GPP Release 11: Understanding the Standards for HSPA+ and LTE-Advanced Enhancements Third Generation Partnership Project (3GPP) standards have successfully driven the mobile marketplace to more than 6 billion connections worldwide. That number continues to grow as the number of devices and the expanse of connectivity into Machine to Machine (M2M) and many vertical industries magnifies. This is further exemplified by the growth in data traffic as smartphones, tablets and rich services like video have reached peaks never imagined in past years. There is a continuing story for 3GPP evolution in the coming years with further enhancements to High Speed Packet Access (HSPA/HSPA+) and to Long Term Evolution (LTE/LTE-Advanced) to enable advanced services and support the growing exabytes of mobile data traffic. Progress on 3GPP standards is measured by the milestones achieved in particular Releases. New features are ‘functionality frozen’ and are ready for implementation when a Release is co mpleted. 3GPP works on a number of Releases in parallel, starting future work well in advance of the completion of the current Release (Rel). Although this adds some complexity to the work of the groups, progress is continuous and stable. 3GPP standards development falls into three principal areas: radio interfaces, core networks and services. 3GPP Rel-11 standards for HSPA+ and LTE-Advanced were frozen in December 2012 with the core network protocols stable in December 2012 and radio access network (RAN) protocols stable in March 2013. For HSPA, Rel- 11 introduces new capabilities such as 8-carrier downlink operation (HSDPA), Downlink (DL) 4-branch Multiple Input Multiple Output (MIMO) antennas (either one
