Anyone implemented TD-LTE subframe other than 2?

2

Yes. We did that. Whats ur need??

3

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

4

what will be the impact on KPIs and unforseen issue?

5

Which provider?

6

perhaps some UEs don’t support config 5. The provider/vendor is Huawei.

Note that Huawei doesn’t support config 4

7

Which release note??

8

and for massive MIMO only config 2 is supported

eRAN8.1

Ok bro
So u have to be sure rhat software is supporting conf 4 and 5
Be sure also about ue capability

10

For massive MIMO i remenber that u need to upgrade to ran12.10

11

yes it is in our roadmap

12

Massive MIMO u have to use 65t/64r

13

yes I know

14

Also in ur road map?? Good

Soft split is ur road map also??

15

do u have any practical experience?

16

Yes. 5 years LTE leader FDD and TDD

17

so did u face any issue when changing config

18

Now i’m managing 8T/8R solution…with eran12.1.

Yes

19

I am talking about experience regarding my query

20

Yes. I faced problems. The network support only one conf
