Improvement of throughput in high utilization apart from mlb or coverage traffic shifting or idle mode balancing.

First of all need to know the reason for high PRB utilisation. Is it genuine due to high demand from more attached users and generated traffic. else we can see the TA and bad coverage samples along with RSRP distribution along with supporting KPIs like modulation and CQI.Users more at cell edge can be limited by power parameters like pzeronominalpusch and pzeronominalpucch If all is well then we need caapcity build up which can be done either by optimization physically or using IFLB with other bands in idle or connected mode if available. Check for the possibility of bandwidth upgradation of license is present. If Volte is present then SPS can be tried to further freeing PRBs… There’s many optimization techniques further to it all depends upon the present situation

You can increase thruput by adding another LTE carrier if the reason is high traffic (user) , this can be
1-adding new sector
2-apply sectorization (splitting the current cell to two beam (Huawei)
3-finally adding capacity site in that hotspot zone

Hello.
Is there a way to improve DL Throughput in 4G FDD with DL PRB utilization of 70 %?
Allocated band is 15 MHz ( which obviously can not be increased).
Is there any parameter to improve the Throughput?
Vendor is Huawei.
EPF capacity factor, RB priority.
Also you can tune RS Power, Pa Pb.

you can use
- Carrier aggregation
- 4X4 MIMO
3.phyical action like Tilt or CELL SPLIT

Yes agree.
Parameter will not much help.
- CA.
- MIMO or Massive MIMO.
- Split Cell, Add Sector, & Multisector.
Kindly help me understand Pa Pb.
Also what are the steps/distances of LTE TA, like 3G = 234.
I have seen with Huawei they are from 0-11 index
