Hi, you should check:

  1. CCE capacity such as no of pdcch symbols, fixed or dynamic.
  2. CCE usage percentage of UL, DL or common channels.
  3. Power offset of dci with rs, one cause of cce failure is due to not enough power for pdcch channel

Hi @Manoj_deka, As you mentioned low utilized cells which indicates obviously capacity and congestion is not an issue.

You may try PDCCH power enhanced feature, this also helps in PDCCH coverage boost poor coverage and quality
You may try feature related to PDCCH link adaptation.
