Hello Experts,

I am looking at E**** pmPrbUtilDl OSS counters data and see the following matrix (below). How to caluclate the PRB utilization ?

I am using the formula:
(pmPrbUtilDl_1 (59) * average_util (4.5%) + pmPrbUtilDl_2 (1) * average_util (14.5%) + ..... ) / 60 = 4.6%

but I could also use the maximum
(pmPrbUtilDl_1 (59) * average_util (9%) + pmPrbUtilDl_2 (1) * average_util (19%) + ..... ) / 60 = 9.2%

So the utilization can really be anything between 4.6% to 9.2% .... what is the consensus on the value to use?

Maybe I shall use the maximum to be on the most restrictive side.

As I understand correct, you talr about prb utilization average and by busy hour.
You can use average for kpis, but maximum for analyzing problems on network such congested cells

yes you are correct, I am talking about prb utilization average and by busy hour.
Many thanks for your response !!!
