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?

#15
