Livenetwork cqi report. This example demonstrates how to measure the Channel Quality Indicator (CQI) reporting performance using the LTE Toolbox™ under conformance test conditions as defined in TS36. 1. CQI Measurement in Livenetwork. CSI report is triggered by DCI, so a certain DCI format can influence CSI Report as described in CQI Report and SR section. . The tool has capability of RRC / NAS message capturing and decoding This example shows how to compute downlink CSI parameters such as the CQI and PMI from type I single-panel codebooks and RI for a MIMO scenario with a TDL channel. Following is an example configuration from a live network captured by a drive test tool from Azenqos. 101 Section 9. CQI Measurement in Livenetwork. 3. The table above shows the CQI value mapped in MCS and coding efficiency. g, CQI request, CSI request field) or some fields which influence CSI measurement process (e. Channel Quality Indicator (CQI) is a crucial metric in Long-Term Evolution (LTE) networks, providing information about the quality of the communication channel between the User Equipment (UE) and the eNodeB (base station). 2. Depending which value UE reports, network transmit data with different transport block size. The example also supports the computation of CSI parameters using type I multi-panel, type II, and enhanced type II codebooks. In many cases, DCI carries some special field that is requesting specific CSI report (e. 30 indicates the best channel quality and 0,1 indicates the poorest channel quality. Example 1 : Live Network Example - CQI, RI, PMI . g, Precoding Matrix info). A low CQI value means that a more robust modulation is required and the code rate will be low, while a higher CQI value indicates that higher code rate can be supported by the channel. What would happen if UE send inaccurate CQI ? In HSDPA, the CQI value ranges from 0 ~ 30. krfknlaxsxaqvmdzrzbhblsaiojttshexrceowzdquxphbkhatr
