LTE UE capabilities Interpretation of Bandwidth Combination Set values shown in CMW Callbox

Question

When obtaining the UE capabilities and select Band combinations vs Parameter option the BW Combination Set column provides information related to binary numbers in various band combinations (images as reference can be found below).

The question is how to interpret those numbers to the Bandwidth Combination Set for each CA specified in 3GPP TS 36.101.

Answer

The table "Band combinations vs Parameter" contains one row per shown band combination.

The columns indicate the bands. Column "BW Comb. Set" indicates which bandwidth combination sets are supported for a band combination. The leftmost bit corresponds to set 0, the next bit to set 1, and so on. "0" means that the set is not supported. "1" means that the set is supported. The sets are specified in 3GPP TS 36.101, chapter 5.6A.1.

So for example in your case the band combination Band 66 + Band 12 has six posible BW Comb. Sets:
