Future Radio Access LTE is rapidly emerging as the dominating 4G standard throughout the world, taking mobile broadband to unprecedented performance levels.? The latest version of the LTE standard, known as Rel-10 or LTE-Advanced, by a wide margin fulfills the IMT-Advanced requirements and is one of two technologies approved by ITU as IMT-Advanced compliant.? Currently, 3GPP is focusing on Rel-11, taking LTE further beyond the IMT-Advanced requirements.
This talk will provide an overview of the main technology components of LTE-Advanced â?? enhanced multi-antenna transmission, relaying and carrier aggregation â?? as well as components such as CoMP and dynamic TDD considered for future LTE releases.? In addition to these techniques, meeting future demands for even higher data rates requires a denser infrastructure, for example in the form of a heterogeneous deployment where low-power nodes complement the basic coverage provided by a macro cell.
Such deployments are expected to become increasingly important in the future and may call for enhancements in, for example, inter-cell interference management, as well as further stress the importance of energy efficiency given the large number of nodes.? The increasing usage of machine-type communications, where the challenge often is the enormous amount of devices connected rather than the data rates themselves, is another focus area for future radio access.? The presentation will discuss these challenges, as well as others, and some technologies for addressing them.
