LTE ADVANCED REL 10

Wider bandwidth transmission using carrier aggregation• Entire system bandwidth up to, e.g., 100 MHz, comprises multiple basic

frequency blocks called component carriers (CCs) 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

TECNICAS LTE ADVANCED: AGREGACION CANALES

Extension up to 8-stream transmission• Rel. 8 LTE supports up to 4-stream transmission, LTE-Advanced supports up to 8-

stream transmission Satisfy the requirement for peak spectrum efficiency, i.e., 30 bps/Hz

Specify additional reference signals (RS)• Two RSs are specified in addition to Rel. 8 common RS (CRS)

- Channel state information RS (CSI-RS)- UE-specific demodulation RS (DM-RS)

UE-specific DM-RS, which is precoded, makes it possible to apply non-codebook-based precoding

UE-specific DM-RS will enable application of enhanced multi-user beamforming such as zero forcing (ZF) for, e.g., 4-by-2 MIMO
