Power Resource Analysis
Power congestion occurs if RTWP and TCP values
are larger than pre-set thresholds.
If downlink power congestion occurs, we can enable
the LDR and OLC function.
If uplink power is restricted, we can check whether
any interference exists.
Page48
Copyright © 2013 Huawei Technologies Co., Ltd. All rights reserved.
Uplink Load
In a WCDMA system, the RTWP value minus the cell
background noise is the noise increase that results
from a service increase. The noise increase (%)
represents the uplink service increase. For example,
a 3 dB noise increase corresponds to 50% uplink
load and a 6 dB noise increase corresponds to 75%
uplink load.

Downlink Load
The downlink capacity of a cell is limited by its total
available transmit power, which is determined by the
base station amplifier and by software settings.
When the downlink power is exhausted, the following
may occur:
The cell coverage decreases.
The data throughput decreases.
The service quality declines.
New call requests are rejected.
Page52

Downlink Load
In a WCDMA system, TCP is defined to measure the
downlink total transmit power. For Huawei RNCs, four
TCP-associated counters are defined:
VS.MeanTCP: mean carrier transmit power in a cell
VS.MaxTCP: maximum carrier transmit power in a
cell
VS.MinTCP: minimum carrier transmit power in a
cell
VS.MeanTCP.NonHS: mean downlink carrier
transmit power for non-HSDPA in a cell Page53

CE Resource Consumption Analysis Cells under one NodeB share CEs. Common channels
have reserved CE resources and signaling is carried
on a channel accompanying the DCH. Therefore,
CCHs and signaling are considered not to consume
CEs.

Cell Channel Element Load
According to Huawei definition, the Cell Channel
Element Load is calculate by the following formula: UL CE Utility Ratio (NodeB) = UL mean used CE
number in BH / configured UL CE number
DL CE Utility Ratio (NodeB) = DL mean used CE
number in BH / configured DL CE number where
UL mean used CE number = VS.LC.ULCreditUsed.Mean / 2
DL mean used CE number = VS.LC.DLCreditUsed.Mean

Cell DL OVSF Code Load According to Huawei definition, the Cell DL OVSF
Code Load is calculate by the following formula: R99 Code Utility Ratio = R99 mean used code in BH /
max R99 Available code
Related counter: VS.RAB.SFOccupy (ID: 67203416)
Note: The code number is normalized to SF = 256 The occupied codes are the codes occupied by the common
channel, R99 user, and HS-DSCH

Cell DL OVSF Code Load Related counter:
VS. SingleRAB.SF* (* stand for different spreading factor)
Number of Single-RAB UEs Occupy the Codes with Different Spreading Factors of 4/8/16/32/64/128/256 in a cell
VS.MultRAB.SF* (* stand for different spreading factor)
Number of Multi-RAB UEs Occupy the Codes with Different Spreading Factors of 4/8/16/32/64/128/256 in a cell
VS.RAB.SFOccupy
Mean Number of SFs that Have Been Occupied (Let the SFs that Have Been Occupied a Unitary SF of 256) for Cell

Cell DL OVSF Code Load
R99 Code Utilization = [(VS.SingleRAB.SF4+VS.MultRAB.SF4) x 64+
(VS.SingleRAB.SF8+VS.MultRAB.SF8) x 32 +
(VS.SingleRAB.SF16+VS.MultRAB.SF16) x 16 +
(VS.SingleRAB.SF32+VS.MultRAB.SF32) x 8+
(VS.SingleRAB.SF64+VS.MultRAB.SF64) x 4 +
(VS.SingleRAB.SF128+VS.MultRAB.SF128) x 2 +
(VS.SingleRAB.SF256+VS.MultRAB.SF256)]/256 x 100%
Total Code utilization for a cell:
VS.RAB.SFOccupy /256
The value would be greater than the real usage as the
code for HSDPA was reserved initially.
