High PRB Usage Solutions

[Lotengan_Kelvin]

Discussion of High PRB Utilization is a function to User Throughput and Avg connected users.
Optimization is ofloading users to 3G Layers or addition of another LTE Layer

What do you mean? Im asking about the functionality of thr switch

Much thanks!!

[Ryan]

@Ghazy_Mohammed any help please?

@Elmoustapha

PdcchPowerEnhancedSwitch: Indicates whether to enable enhanced PDCCH power control. If this switch is turned on, the eNodeB selects appropriate PDCCH transmit power based on channel quality to increase PDCCH capacity. This parameter is valid only for FDD, not for TDD.

If this switch is turned on, the eNodeB selects a lower aggregation level and increases the transmit power to ensure the PDCCH demodulation performance, allow the PDCCH to support more UEs, and increase the uplink and downlink throughput.

If this switch is turned off, the eNodeB selects a higher aggregation level and the operator needs to configure the transmit power manually.

could you please elaborate more about that parameter and how it works?

if you can’t add new carrier and then add new sites
anyway many way to improve your capacity with improve your RF quality, then your Spectral more efficient . back to basic theory Shannon–Hartley theorem

@Cesar_Nunes

I am using:

• PDCCHCAPACITYIMPROVESWITCH ON
• PDCCHPOWERENHANCEDSWITCH ON
• PDCCHINITIALCCEADJUSTVALUE -10
• PDCCHPOWERBOOSTUPPERLIMIT 3dB

The question is between using -5 or -10 in PDCCHINITIALCCEADJUSTVALUE.
Which one is better to Throughput Optimization?

what is mml command for changing these parameters?

@Cesar_Nunes what is the mml commands for these parameters

[RFGirl]

These parameters are in CELLPDCCHALGO MO.

So, create your MML accordingly.

[Mohammad_Din_Ashna]

You can conversion this cell to 4x4 MIMO

Hi Experts.

In ZTE 4G I’ve a lot of cells (1 carrier only) which the PRB Usage is >85% and at these hours the RRC connect user is high and make DL Throughput is slow.
Do you have any optimizatiion suggestion to try to improve the Throughput?
