MULTIPLE DESCRIPTION CODING (MDC) FOR CHANNEL STATE INFORMATION REFERENCE SIGNALS (CSI-RS)

摘要

Aspects of the present disclosure include a wireless system to reduce quantization error due to codebook-based PMI reporting by precoding channel state information reference signals (CSI-RSs) via a base station. The eNodeB varies the properties for a CSI-RS transmission in a known pattern and receives varying reports from the UE. The eNodeB can reconstruct the PMI with improved accuracy by combining multiple consecutive reports.
