Uplink feedback for supporting MIMO operation in the LTE downlink |
摘要 |
A quantization method of transmission of channel quality information (CQI) includes measuring two measurements SINRs and calculating a difference (i.e., Delta SINR) between the two measurements of the SINRs; determining a CQIbase (base channel quality information) based on one of the two measurements SINRs and a known quantization table for the CQIbase, and simultaneously receiving cell-specific or UE-specific parameters transmitted from a base station and configuring a quantization table defining a mapping method of CQIdelta (delta channel quality information) and the Delta SINR and determining the CQIdelta based on the obtained Delta SINR and the configured quantization table; and transmitting the resulting CQIdelta and CQIbase.
