[Ask] Power congestion in Huawei WCDMA

[lamagica]

hi guys,

in the network i supervised, there are some cells experienced power congestion. in huawei system, how is the best solution to solved this problem. many thanks for your response.

maybe overlaping coverage.

Hi,

If the cell in a real ower congestion ,power upgrade is necessary but there are some ideas to reduce the power congestion:
1- Check the SHO ratio, try to minimize the SHO overheads
2- Push PS users to be mapped over HSDPA
3- Check the coverage, CPICH foot print, reducing the CPICH or downtilting the antenna may reduce the coverage and save some power from boarder users
4- Ensure that VSWR is normal
5- Try to use Micro NodeBs with Fiber connectivity to decrease the feeder losses
good luck.

please add rep if this is useful

you can also enable LDR feature for the power congestion, there are many actions like InterRAT handover and Rate reduction.

Hi all,
All the said above is good approach.
Just to share some of my thoughts -
check if this is UL or DL power congestion.
In case it is UL Call admission control can be modified by increasing "Uplink total equivalent user number" if it is set to low levels (e.g the default one -feel free to try higher values 100, 100+). If it is DL check the HW type - maybe MAXTXPWR is not set to the maximum allowed by the HW (e.g MTRU supports 46 dBm but Max TXPOWER is set to 43 dBM).

I thin this can be the last solution.
it is better to follow the steps described by Sala70..
start by checking SHO rate

HI all,

If there are UL power congestion,maybe the SSCCH power is lower to the baseline value.

questions not spesifik, what's power congestion happend?

1. HSUPA.Power.Cong
2. R99.Power.Cong
3. HSDPA.Power.Cong

Hi,

for the HSPA, beside the R99 service power,Nodeb will assaign all power to HSPA service when HSPA need more power.And the power of R99 is a constant value,but the power of HSPA is not fix.
