Is there any relevance of TTI bundling in 5G?

Guys, I have a question.
Is there any relevance of TTI bundling in 5G?

It is commonly used in Voice Service.
May be if you have VoNR.

Not a single operator yet launched VoNR I guess.
Ericsson said in Q4 2021 VoNR will be launched.

Yes. It is known as slot aggregation. Not limited to VoNR. It is more applicable to URLLC than eMBB that’s why it has not been implemented yet by vendors
