Anyone implemented TD-LTE subframe other than 2?
Yes. We did that. Whats ur need??
theoritically shifting from 5ms (subframe config 2) to 10ms (subframe config 4 or 5) will make less opportunity for ul feedback such as HARQ, BSR etc. and uplink resources will limit
currently we have 10:1 DL:UL traffic ratio and we are using config 2 which is 3:1 (DL:UL). So I was thinking why not move to config. 4 or 5
i was looking for any report or case study when moving from config 2 to 4 or 5
what will be the impact on KPIs and unforseen issue?
perhaps some UEs don’t support config 5. The provider/vendor is Huawei.
Note that Huawei doesn’t support config 4
Which release note??
and for massive MIMO only config 2 is supported
So u have to be sure rhat software is supporting conf 4 and 5
Be sure also about ue capability
For massive MIMO i remenber that u need to upgrade to ran12.10
yes it is in our roadmap
Massive MIMO u have to use 65t/64r
yes I know
Also in ur road map?? Good
Soft split is ur road map also??
do u have any practical experience?
Yes. 5 years LTE leader FDD and TDD
so did u face any issue when changing config
Now i’m managing 8T/8R solution…with eran12.1.
I am talking about experience regarding my query
Yes. I faced problems. The network support only one conf
