Good RSRP, CINR but bad RSRQ ?

Dear experts
We do driving test scanner - data thoughput LTE 4G-Mimo 2x2 in a small area within 5 sites. The % samples of RSRP > -100dBM is good, over 95%, CINR ok with 100% > 0, Download and upload speed are high , over 35Mbps. However, the % samples of RSRQ > -14dB is just 60%, too low. Please give me your advice about this problem
Tks a lot

Hi,

RSRQ depends on on load in serving cell. In your case the testplan (i.e. downloading) is pushing RSRQ downwards. Do the same DT with low DL load, e.g. small ping packets

You mean doing data thoughput at the same time with scanner make RSRQ low ? I don't think so because I tested with many different areas, just only 01 cluster have this problem
