This paper provides a high-level overview of LTE Rel-10, sometimes referred to as LTE-Advanced. First, a brief overview of the first release of LTE and some of its technology components are given, followed by a discussion on the IMTAdvanced requirements. The technology enhancements introduced to LTE in Rel-10, carrier aggregation, improved multiantenna support, relaying and improved support for heterogeneous deployments, are described. The paper is concluded with simulation results, showing that LTE Rel-10 fulfills and even surpasses the requirements for IMT-Advanced.
