One question, in E// vendor, appart of Carrier aggregation feature, do we need any other feature to activate?
In this case we have WCDMA 2 carriers, LTE MBB B3 band, B3 5mhz FWA, and the added and new carrier is B8 3MHz FWA.
All the baseline and configuration for the CA is “ok” until we tried to test on field if the feature is working and nothing happens, we cannot get information with the counters and with the devices on field (CPE outdoor and indoor, no cellphones in this case) carrier aggregation is not working properly.
check Scellcandidate value in EUtranCellRelation MO, it should be set to 1: 1 active
2 auto
0 deactive
I also suggest to verify CPE capability first, there are many Cat 4 CPEs without CA support in the market. if you want to really make sure, try to capture UE capability message throughS1 Trace and see the Category and band combinations. even for UEs with CA capability all band combinations and CA classes are not supported.
Scell candidate should set 1 between carrier 1 and 2 and between carrier 2 and 1. Also check partially swap issue in site it can highly impacted CA performance
