e*** pmPrbUtilDl
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
