2 Overview
2.1 Feature Introduction
2.1.1 Load Adaptive Power Control
There are high load cells in the real network system the load difference of these cells
between busy hour and idle hour is very large. The fixed power control parameters
cannot satisfy simultaneously the requirements of service quality and system capacity
when the load of the cell is changed with time. So the load adaptive power control is
introduced to improve system capacity when the load of the cell is high in busy hour and
protect the service quality when the load of the cell is low during idle hour. At the same

time, the users with higher priority hope to be served better service quality. In order to
embody the Qos difference among the users with different priority, so the power control
parameters can be configured according to the priority.
2.2 License Control

3 Technical Description
3.1 Load Adaptive Power Control
This algorithm can provide better service quality when the cell load is low and decrease
the service quality when the cell load is high, in this way, more online users can be
supported when the load is very high. At the same time, the users with different priorities
can get different service quality.
Firstly, the three cell load levels are defined. They are low Load, medium load and high
load. The three user types based on allocation priority are defined. They are golden-level
user, silver-level user and bronze-level user.
Some power control parameters are designed as 9-element arrays, each element is
relative to cell load and user priority as the following:
Element 1: low load, golden-level user;
Element 2: low load, silver-level user;
Element 3: low load, bronze-level user;
Element 4: medium load, golden-level user;
Element 5: medium load, silver-level user;
Element 6: medium load, bronze-level user;
Element 7: high load, golden-level user;
Element 8: high load, silver-level user;
Element 9: high load, bronze-level user.

About the details of power control parameters above mentioned, please refer to ZTE
UMTS Power Control Feature Guide, ZTE UMTS HSUPA Introduction Feature Guide,
and ZTE UMTS Power Control Algorithm Enhancement Feature Guide .
When the service is accessed or reconfigured, the power control parameters are
obtained according to the following principle.
1. When the switch UCelInfoFDD.blerLoadSwitch is on, the uplink and downlink
power control parameters are determined from the 9-element parameters based on
the uplink real cell load and downlink real cell load respectively. Otherwise, the
power control parameters are determined based on the default cell load level
indicated by UCelInfoFDD.defaultLoadLevel.
2. When the switch URncInfo.blerArpSwitchis on, the power control parameters are
determined based on the user priority indicated by ARP (Allocation/Retention
priority) .If the switch is off or the ARP information cannot be obtained, the
parameters are determined based on user priority indicated by the default ARP
configured by URncInfo.defaultArpSeg.

Load Level Estimate
User Priority Identification
The uplink load level, the downlink load level of the cell, and the ARP segment of the
user are determined as the following:
1. The uplink load level of the cell
The uplink load level of the cell is obtained based on RoT and equivalent AMR user
number. And ZTE RNC chooses the lower level between the RoT level and uplink
equivalent AMR user number level as uplink load level.
Where,
i. RoT level is determined as following method:
ZTE RNC will record the common measurement result of RTWP, and filter the
RoT according to the following formula:
RoT(t)= * RoTreport + (1-)*RoT(t-1) (3.1-1)
Where,
-
7/26/2019 ZTE UMTS Load Adaptive Power Control Feature Guide

Load Adaptive Power Control
ZTE Confidential Proprietary 11
is the filter factor, and obtained from URncInfo.loadFilterCoeff.
RoTreport is the report of the current RTWP common measurement. The
formula is: RoT(dB) = RTWP (dBm) - Background noise (dBm).
RoT(t-1) is the filter result last time.
RoT(t) is the filter result this time.
The RoT level is determined through making a comparison between the filter
result RoT(t) and the related threshold as following table:
Table 3-1 RoT Level
RoT Level RoT
Level 1: Low RoT level
RoT < UCelInfoFDD.lowRotThreshold
Level 2: Medium RoT level
UCelInfoFDD.lowRotThreshold = UCelInfoFDD.highRotThreshold
ii. Uplink equivalent AMR user number level is determined as following method:
The load factor of single service is calculated as:
(3.1-2)
Firstly, RNC will calculate the load factor of the NB-AMR service (LAmr) and the
load factor of service (i) (Li) according to the formula (3.1-2), and then
calculate the equivalent AMR user number of the service (i) according to the
formula (3.1-3):
(3.1-3)
Where,
a) is load factor of the service (i), and is the load factor of the
NB-AMR service.

b) Eb/No is the uplink service quality factor. It is obtained from the
parameter USubSrv.ulEbN0Pc for the DCH and non-schedule E-DCH
service, and it is obtained from the parameter USubSrv.sEdchEbN0Pc for
the schedule E-DCH service. The unit of USubSrv.ulEbN0Pc and
USubSrv.sEdchEbN0Pc is dB, so they will be transferred through the
formula 10^(USubSrv.ulEbN0Pc/10) and
10^(USubSrv.sEdchEbN0Pc/10) in the calculation.
c) R: it is the target rate for DCH and non-schedule E-DCH services, it is
GBR for the schedule E-DCH services, it is NBR indicated by
UCelInfoFDD.rsrvdBitRate for the interactive or background E-DCH
services.
d) W is 3.84Mbps.
The single signaling will also be calculated the equivalent AMR user number
according to the rules above-mentioned.
And for avoiding the influence to the power control parameters caused by the
fluctuating of equivalent AMR user number, the equivalent AMR user number
will be filtered as the following formula:
UserNum(n) = * UserNumSample + (1-)*UserNum(n-1) (3.1-4)
Where,
a) is the filter factor , and is obtained form URncInfo.userNumFilterCoeff.
b) UserNumSample is the current equivalent AMR number.
c) UserNum(n-1) is the filter result last time.
d) UserNum(n) is the filter result this time.
The equivalent AMR user number level is determined through making a
comparison between the filter result UserNum(n) and the related threshold as
following table:

6.5 Network Impact
1. Impact of Equipment Performance
After the feature is activated, the cell load level will be calculated all the time, it
contains RoT, uplink equivalent AMR user number and downlink load, so the CPU
load of the RNC will be increased. The CPU load of CMP board will be increased
about 0.5%, and the CPU load of DMP board will be increased about 1%.
2. Impact of Network KPI
i. Load adaptive power control
Activating this feature, the advantage is:
The feature is suit for the network that the load is changed with time severelyor some cell load is high. The different values for power control parameters are
configured for different load level, the power control parameters with low
requirement are used by the high load cell, and it will improve the system
capacity and the basic KPI performance of the network, such as increasing the
ratio of successful call setup, decreasing the call drop ratio. And the power
control parameters with high requirement are used by the low load cell, and it
will improve the user experience.
In the test scene, when the feature the load adaptive power controland the
feature power control algorithm enhancementare activated simultaneously,
the KPI performance is following. About the feature power control algorithm
enhancement, please refer to the ZTE UMTS Power Control Algorithm
Enhancement Feature Guide.
UL load per UL throughput is reduced by 6%~17%.
HSUPA throughput in high load condition is increased about 7%~11%.
-
7/26/2019 ZTE UMTS Load Adaptive Power Control Feature Guide
51/53
Load Adaptive Power Control
ZTE Confidential Proprietary 50
Call drop ratio of the PS service is reduced by 7%~20%.
Other KPIs have no affection.
The disadvantage is:
When the cell load is high load level, the service quality is decreased
comparing with the service quality when the cell load is low load level.
ii. ARP adaptive power control
Activating this feature, the advantage is:
The function is suit for the network that has the subscribers with different
priorities, the subscribers with high priority use the power control parameters
for good service quality, and the subscribers with low priority use the power
control parameters for poor service quality. The service quality of the
subscriber with high priority can be improved.
The disadvantage is:
The service quality of the subscriber with low priority will be decreased.
iii. The load adaptive power control and the ARP adaptive power control are
activated at the same time.
The advantage is:
If there are users with different priority in the network, and the service quality of
the subscribers has been decreased after the load adaptive power control
function has been used. Activating the ARP adaptive power control functioncan make the different priority users with different service quality, and the
service quality of the user with higher priority still can be good.
The disadvantage is:
None.
