LTE Advanced – Introduction
• • LTE FDD and TDD have a clear evaluation towards LTE-Advanced. LTE Advanced requirement
 Downlink transmission scheme.  Data rate 100Mbps high mobility, 1Gbps low mobility  Improvements to LTE by using 8x8MIMO  Uplink transmission scheme. Up to 500Mbps  Relay functionality  Backward compatibility with LTE
•
LTE Advanced Spec
 3GPP published R10 standard in March 2011 and froze LTE-A features.  R11 spec is expected to be finished in H2 2012.
Slide 17


Carrier Aggregation – Technical Information
• • Wider bandwidth transmission using carrier aggregation. Entire system bandwidth up to, e.g., 100 MHz, comprises multiple basic frequency blocks called component carriers (cc). – Satisfy requirements for peak data rate. • Each CC is backward compatible with Rel. 8 LTE. – Maintain backward compatibility with Rel. 8 LTE. • Carrier aggregation supports both contiguous and non-contiguous spectrums, and asymmetric bandwidth for FDD. – Achieve flexible spectrum usage.
