5G Slot Format Configuration: Impact on Performance

[@farshadesmaeli755]

thank you, have you ever tried to change the UL/DL ratio in flexible slot? if yes, is there any great improvement ?

I did it by myself only for 4G TDD through changing ssp from ssp5 to 7 which brought a good gain in dl throughout at that time but interference increased due to GP symbol reduction

So as i understand we have to be careful while configuring the slot and taking into account the different control channel specially for RACH procedure . Also i have to mentionne that if we increase the number of UL slot , maybe the number of UE can increase . But my question in case we have multiple UE is how the gNB did the allocation is it in term of slot or mini slot or symbols .

Hi Khaled; regarding your question; actually the current used and supported configuration in both 4G and 5G TDD is the static allocations means that there is no option that different UE can have different slot allocation however 5G support a dynamic TDD allocation(didnt try before) where the gnb can assign a dedicated and different configuration for the available flexible slot but this might also cause something called cross link interference; you may watch the pervious video which may give you some clarity
