Wireless data consumption is increasing faster now than ever before,” said Adrian Scrase, 3GPP Head of Mobile Competence Center. “Smartphone usage is experiencing higher volumes and the superior user experience offered by such devices is resulting in quickly rising demand and escalating use of wireless data applications. This is consequently driving the need for continued innovations that are supported by the efficient and successful 3GPP technology path.”
3GPP Mobile Broadband Innovation Path to 4G: Release 9, Release 10 and Beyond: HSPA+, SAE/LTE and LTE-Advanced, is a comprehensive resource intended to assist members of the wireless industry as well as interested members of the general public in understanding details of the work in 3GPP on Release 9 and Release 10. In addition, the report further describes the features of Release 8 that were closed in March 2009.
Release 9, which is targeted for completion by March 2010, will provide increased feature functionality and performance enhancements to both HSPA and LTE. The report reviews additional multi-carrier and MIMO options for HSPA and features and enhancements to support emergency services, location services and broadcast services for LTE. Other Release 9 enhancements include those to support Home NodeB/eNodeB (i.e. femtocells), Self-Organizing/Self-Optimizing Networks (SON) and the evolution of the IP Multimedia Subsystem (IMS) architecture.
While work for Release 9 is nearing completion, significant progress has already been made in 3GPP on work for Release 10, which includes LTE-Advanced. In fact, 3GPP already submitted a proposal in October 2009 based on LTE-Advanced for the IMT-Advanced evaluation and certification process led by the International Telecommunication Union (ITU). The ITU has defined requirements that will officially define and certify technologies as IMT-Advanced, or 4G, and is expected to evaluate submitted proposals by standards organizations for potential certification in the 2010 timeframe; certified 4G/IMT-Advanced technology specifications are projected to be published by early 2011.
As part of Release 10, some of the key LTE-Advanced technology enhancements include carrier aggregation, multi-antenna enhancements and relays. Assuming LTE-Advanced is certified to be IMT-Advanced compliant, 3GPP targets completion of the Release 10 specification by year-end 2010.
“The white paper by 3G Americas provides an excellent overview of the work by 3GPP in determining the standards on the path to 4G,” Scrase said.
The popular white paper, 3GPP Mobile Broadband Innovation Path to 4G: Release 9, Release 10 and Beyond: HSPA+, SAE/LTE and LTE-Advanced, was written collaboratively by members of 3G Americas and is available for free downloadon the 3G Americas website at www.3gamericas.org.
