WebCQI (Channel Qulity Information) PMI (Precoding Matrix Indicator) CRI (CSI-RS Resource Indicator) SSBRI (SS/PBCH Resource Block Indicator) LI (Layer Indicator) RI (Rank Indicator) an/or L1-RSRP Higher Layer Framework of CSI Report CSI Report framework is made up of two large parts. Webframework, the BS chooses the MCS based on the channel quality indicator (CQI) reported by the user equipment (UE). A transmission is made with the chosen MCS and the results of this transmission are converted by the BS into rewards that the BS uses to learn the suitable mapping from CQI to MCS.

WebCQI (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. WebOct 19, 2024 · For the Data Scheduling, there are two algorithms that work together. The first one is based on CSI reports where the UE receives CSI-RS/CSI-IM and estimate CSI feedback (CQI,RI,PMI) and then sends this CSI feedback to the gNB. The gNB uses this CSI feedback to assign MCS and MIMO layers to the UE. The second part of the algorithm …

WebSep 6, 2016 · Overall sequence of CQI report and eNB reaction to the report is as follows : i) UE sends a CQI report with a certain value (e.g, 15) ii) eNB sends PDSCH with the highest MCS (i.e, the highest code rate and the largest transport block) iii) If UE can successfully decode it (meaning BLER lower than a certain limit), it sends the same or higher CQI.
