In which type of CQI feedback mode the UE reports the subband CQI for each band in a single feedback report?

Higher layer configured subbandreporting: UE reports the subbandCQI for each band in a single feedback report.

Which channel carries CQI information to Enodeb?

CQI is carried by PUCCH or PUSCH depending on the situation as follows. Regarding CQI report period and configuration, refer to CQI, PMI, RI Reporting Configuration part.

How is CQI measured in LTE?

CQI (Channel Quality Indication) – Instead of expressing the CQI as a received signal quality, the CQI expressed as a data rate that terminal (UE) can support under the actual radio conditions. SINR is used for calculating CQI. In LTE, CQI has only 15 codes. MCS parameter is assigned based on the CQI value.

What is a good CQI value in LTE?

1) Current Communication Channel Quality is this-and-that.. In HSDPA, the CQI value ranges from 0 ~ 30. 30 indicates the best channel quality and 0,1 indicates the poorest channel quality.

What is CQI PMI RI in LTE?

CQI is Channel Quality Indicator. PMI stands for Pre-coding Matrix Indicator, and RI is Rank Indicator. These three values are computed on the fly in LTE systems and used to try to optimize resource allocation among the various user end devices (UEs) that are requesting service.

What is CQI range in LTE?

between 0 and 15
In the LTE system, the CQI is used by the mobile to indicate the channel quality to the eNB. The CQI reported value is between 0 and 15. This indicates the level of modulation and coding the UE could operate.

What is good CQI in LTE?

In HSDPA, the CQI value ranges from 0 ~ 30. 30 indicates the best channel quality and 0,1 indicates the poorest channel quality. Depending which value UE reports, network transmit data with different transport block size.

How many CQI indices are defined in LTE?

15 codes
In LTE, CQI has only 15 codes. MCS parameter is assigned based on the CQI value.
