Power control at the maximum power limit for E-DCH
Samsung
AI 8.3
Discussion

1 Introduction
In previous Cannes meeting, it was agreed that the CCTrCH of E-DCH type and the CCTrCH of DCH type are mapped
to different physical channels. Introduction of the additional physical channel could affect on operation in a UE side.
One of the possible impacts may be power control at the maximum power limit where the total transmission power may
exceed the maximum allowed power.
In this contribution, we analyze the deficiency of the transmission power and investigate the possible options to perform
the power control at maximum power limit considering E-DCH.

2 Deficiency of the transmission power
There seems to be a couple of cases when the total transmission power would exceed the maximum allowed power after
applying DPCCH power adjustments and gain factors. [1]
Closed loop power control: consecutive power up commands might cause power limitation to the LIE even though
there is no problem in TF selection for DCH and E-DCH.
The TF for the retransmission would be the same as the initial transmission: the LIE would select the TF for
the initial transmission considering the remaining transmission power by TF selection in MAC layer but it may not
be true for the retransmission case. At retransmission timing, the LIE could not have the sufficient power for the
same TF as the initial transmission due to channel variation or DCH existence.
Minimum set of TFs for E-DCH: if the LIE supports the minimum set of TFs for E-DCH, the LIE may transmit a
minimum set TF even if the LIE doesn’t have a sufficient power to transmit.

3 Possible options for power control at the maximum power limit
3.1 Equally scaling method
The UE performs additional scaling to the total transmit power so that it is equal to the maximum allowed power in case
that the total LIE transmit power exceeds the maximum allowed value. The additional scaling to the total transmit power
should maintain the original gain factor ratio configured by higher layer. It may be simple to the LIE because the LIE
doesn’t have to distinguish newly included channels, E-DPDCH or E-DPCCH. However, this method could raise some
concerns as follows.
Impact on DCH performance: in this method, DPDCH and E-DPDCH power would be reduced equally at the
maximum power limit. But if there is no E-DPDCH, the LIE may not meet the power limit situation and hence
will not experience the power scaling for DPDCH. It means that DCH performance could be degraded due to EDCH even though DCH has a higher priority than E-DCH. In case of retransmission, this problem could be worse
since MAC layer could not select the E-TF for retransmission considering power margin at retransmission timing.
Shortage of the required power at the next TTI: the LIE sets the required power of DCH or E-DCH with respect to
DPCCH power. If the DPCCH power was scaled down due to E-DCH at previous timing, the UE cannot obtain
the power required to guarantee E-DCH performance even though the required power margin is available. This
kind of problem would be severe if data rate changes very abruptly.

3.2 E-DPDCH only scaling method
The UE reduces only the E-DPDCH power among uplink channels if the total transmission power is larger than the
maximum allowed power. If the reduced gain factor is not a reasonable value, e.g., too small, the UE could decide if it
will transmit the E-DPDCH. If after E-DPDCH scaling, the total transmission power is still larger than the maximum
allowed power, the UE will apply the equal scaling for remain channel like as Rel-99 power control. It is noted that even
though the E-DPDCH power is reduced, E-DPCCH would be better to maintain the given power ratio in order to enable
for the Node-B to decode the E-DPDCH correctly. This method can guarantee for the UE to transmit the DPDCH and
DPCCH with the required power. It would be a natural way to solve the deficiency of transmission power while keeping
the principle that DCH is always prioritized over E-DCH.
There seems to be two possible options for E-DPDCH only scaling method depending on the operation boundary.
E-DPDCH only scaling per TTI: the power scaling could happen at every TTI boundary. It is applicable to solve
the power deficiency problem due to retransmission or minimum set TF transmission. In this method, the UE
would scale E-DPDCH power by expecting the total transmission power per TTI. It is noted that if the amount of
power reduction is very large so that the actual E-DPDCH power offset is smaller than a certain threshold value, it
may be beneficial that the UE doesn’t transmit E-DCH since the UE could try retransmission at next
retransmission timing.
E-DPDCH only scaling per slot: power scaling could happen at every slot. Impact of the slow-wise E-DPDCH
only scaling on the UE implementation is FFS.

4 Conclusion
We discussed some issues about power control operation at the maximum power limit. We can see the E-DPDCH only
scaling method at the maximum power limit would be a better method than the equally scaling method since this kind of
prioritization between data channels could guarantee the performance of DCH, which has a higher priority than E-DCH
as agreed in Cannes..
Regarding the power control at the maximum power limit, we propose to adopt the following as the working assumption.
If the UE expects that the total transmit power would exceed the power limit during a TTI interval, the UE reduces
only the E-DPDCH power offset per TTI.
Feasibility of reducing only the E-DPDCH power offset per slot upon occurrence of the power shortage problem is FF S.
Based on the discussions, we propose to agree on the following text proposal for RAN1 TR 25.808 and to capture them.
