Reasons for increased DL BLER on site

What can be reasons for increase of DL BLER on site considering there is no overlapping, no parameter ambiguity?
Any other reasons?

Low RSRP that gets close to noise level could be one reason.
Did aggregation level for PDCCH increased more for aggregation level 8?
Try to compare.
Or if you modified bler target for PDSCH (should be 10%).

Ok, let me check aggregation level, but it’s less traffic site only 3 to 4 users.
New site. I’m suspecting hardware issue.
Or old remedy: reset on site. :slight_smile:
