dci format1 not decoded
The problem is : we are sometimes missing the DCI format 0 when in the same subframe we have a DCI format0 and format1. This is coded in the following order : dci decoding format0 with aggregation level 4 then aggregation level 3 then 2 then 1. The problem is that here if the format0 is decoded with aggregation level 4, it apply a Mask to CCEmap that doesn't allow the UE to decode the format1 after.
The correction is to start the decoding with Aggregation level 1 and follow with 2,3 and 4.
