LTE has only max of 8 HARQ process either for DL or UL or regardless of TM.

I’ve seen for the Uplink, LTE Advance Carrier Aggregation it is 8 per serving cell (transmission mode 1) and 16 per serving cell (transmission mode 2).

Thanks for sharing, I will check UE logs to see.

As per my knowledge, LTE has 8 HARQ process for DL or UL.

I never seen process ID >8 in logs .

Could you please share the log snippet where you have seen HARQ process till 16 w.r.t TM mode as well.

Thanks !!!
