The unsuitable lifting of DPCCHSIR level of Gu Zuo communityThe identical level of the current DPCCHSIR in Dao Yuyou community, only needs to ensure that RL (Radio does not appear in uplink receiving signal interference ratio Di Zuo communityLink, Radio Link) step-out can achieve the goal, and the target compensation level of Ze Zuo community DPCCH statistic SINR can be left littleMinimum DPCCHSIR level when RL step-out does not appear in district, the highlyest can compensate to the required DPCCHSIR of normal data solution timingLevel, therefore, minimum when the target compensation level of left community DPCCH statistic SINR can Zuo community occur RL step-outBetween the required DPCCHSIR level of DPCCHSIR level and normal data solution timing, the present embodiment Bu Duizuo community DPCCH receivesThe objectives compensation level of signal interference ratio limits. No matter the target compensation level of left community DPCCH statistic SINR is specially manyFew, between the current DPCCH statistic SINR level in the target compensation level Yu Gaizuo community of Gai Zuo community DPCCH statistic SINRDifference can be confirmed as the power bias difference of data channel.
In addition, data channel comprises the up DPDCH of R99 and/or the up E-DPDCH of HSUPA, this step specifically can be divided into asLower three kinds of situations:
The first situation: if data channel is up DPDCH, what this step need to be according to left community DPCCH statistic SINRTarget compensation level is determined the power bias difference of up DPDCH, by the target compensation level of left community DPCCH statistic SINRDifference between the current DPCCH statistic SINR level in Yu Zuo community is defined as the power bias difference of up DPDCH;
The second situation: if data channel is up E-DPDCH, this step need to be according to left community DPCCH statistic SINRTarget compensation level determine the power bias difference of up E-DPDCH, by the target compensation of left community DPCCH statistic SINRDifference between the current DPCCH statistic SINR level in horizontal Yu Zuo community is defined as the power bias difference of up E-DPDCH;
The third situation: if data channel is up DPDCH and up E-DPDCH, this step need to be according to left community DPCCHThe target compensation level of statistic SINR is determined the power bias difference of up DPDCH and the power bias difference of up E-DPDCH,Poor by between the current DPCCH statistic SINR level in the target compensation level Yu Zuo community of left community DPCCH statistic SINRValue is defined as the power bias difference of up DPDCH and the power bias difference of up E-DPDCH. In this kind of situation, left communityDifference between the current DPCCH statistic SINR level in the target compensation level Yu Zuo community of DPCCH statistic SINR is upThe summation of the power bias difference of DPDCH and the power bias difference of up E-DPDCH, and the power bias difference of up DPDCH withConcrete allocation proportion between the power bias difference of up E-DPDCH, the present embodiment is not specifically limited.
For above-mentioned the second situation and the third situation, when data channel is up E-DPDCH, the power bias of this E-DPDCHValue can represent by reference to PO value, and which is specially with reference to reference PO value corresponding to PO in order to distinguish, and also needs by correspondenceReference E-TFCI identify. Therefore, the second situation and the third situation are according to the target of left community DPCCH statistic SINRWhen compensation level is determined the power bias difference of E-DPDCH, can be true according to the target compensation level of left community DPCCH statistic SINRFixed with reference to PO difference, and corresponding reference E-TFCI, the power bias difference with reference to PO difference as E-DPDCH.
403: reduce data letter according to the power bias difference of data channel and for the former power bias value of the data channel of UE configurationThe power bias value in road;
Particularly, this step is according to the power bias difference of data channel and be the former power bias value of the data channel of UE configurationWhile reducing the power bias value of data channel, because above-mentioned steps has been determined the power bias difference of data channel, by willData after can being reduced after the former power bias difference of the power bias difference of this data channel and this data channel mergesThe power bias value of channel.
Dissimilar in conjunction with data channel, this step specifically also can be divided into following three kinds of situations:
The first situation: if data channel is up DPDCH, above-mentioned steps 402 has been determined the power bias of up DPDCHAfter difference, reduce on this according to the power bias difference of up DPDCH and for the former power bias value of the up DPDCH of UE configurationThe power bias value of row DPDCH, by the power bias difference of up DPDCH and the former power bias difference of this up DPDCHThe power bias value of the data channel after the reduction obtaining as this step after merging;
The second situation: if data channel is up E-DPDCH, above-mentioned steps 402 has been determined the power of up E-DPDCHAfter biasing difference, the former power bias value of up E-DPDCH configuring according to the power bias difference of up E-DPDCH and for UEReduce the power bias value of this up E-DPDCH, by the power bias difference of up E-DPDCH and this up E-DPDCHThe power bias value of the data channel after the reduction that former power bias difference obtains as this step after merging;
The third situation: if data channel is up DPDCH and up E-DPDCH, above-mentioned steps 402 has been determined up DPDCHPower bias difference and the power bias difference of up E-DPDCH after, by up to the power bias difference of up DPDCH and thisThe power bias value of up DPDCH after being reduced after the former power bias difference of DPDCH merges, by up E-DPDCHPower bias difference and the former power bias difference of this up E-DPDCH up E-DPDCH after being reduced after mergingPower bias value, the afterwards power bias of the up E-DPDCH by the power bias value of the up DPDCH after reducing and after reducingThe power bias value of the data channel after the reduction that value obtains as this step.
For the above-mentioned the second situation in this step and the third situation, when data channel is up E-DPDCH, after this reductionThe power bias value of up E-DPDCH can represent by reference to PO value, and which is specially with reference to PO correspondence in order to distinguishReference PO value, also need to identify by corresponding reference E-TFCI. Therefore, the above-mentioned the second situation in this step andThe third situation, can be according to reference to PO difference and be the former reference of UE distribution in the time reducing the power bias value of up E-DPDCHPO value reduces with reference to PO value, the power bias value of the up E-DPDCH of the reference PO value after reducing after reducing. Wherein,Reference PO value after reduction with for UE distribute former in the corresponding identical reference E-TFCI of PO value.
