CA or UL CoMP vendors comparison

Hello Experts.

In Nokia, if single baseband doesn’t support FDD and TDD.
In Ericsson everything on same baseband.

Do we see any issue in CA or UL CoMP in Nokia case compare to Ericsson?

Ericsson no issue - CA and ULCOMP works fine.
Nokia I think the updated ABIA+ASIA+AZHA have some version (update) for the same, but not sure… need to check.

Will there be any performance difference between single baseband vs X2 based CA between different baseband?
Any delay in SCC activation compare to single baseband?

As performance, we have not compared much, but definitely, power consumption criteria have a good difference.
