A-DCHs for UL&DL With W11B feature “SRB on HSDPA”, no A-DCH CEs reservation is necessary!! A-dch ce reservation • The cost for 1 A-DCH in RBS6000 is 0.5CE. • The amount of A-DCH resources is reserved by default in a Baseband pool the minimum of Criteria 1 and Criteria 2 below: • Criteria 1 A-DCH CE reserved = 1.3 * sum of the lowest of the values of either the RBS License Key “Number of HSDPA users per Cell” or RbsLocalCell::maxNumHsdpaUsers, determined cell-by-cell * 0.5 For eg, 1st cell: RBS License Key “Number of HSDPA users per Cell” = 64 and MO parameter RBSLocalCell:: maxNumHsdpaUsers = 32 2nd cell: RBS License Key “Number of HSDPA users per Cell” = 64 and MO parameter RBSLocalCell:: maxNumHsdpaUsers = 64 Therefore, A-DCH CE reserved = (32 + 64) x 1.3 x 0.5 = 63 CE • Criteria 2 A-DCH CE reserved = 1.3 * number of HS Resource_ID * 128 * 0.5 Therefore, A-DCH CE reserved = (32 + 64) x 1.3 x 0.5 = 63 CE Example 1 HS EUL Example 1: DUW20 3 cc (32 HS users) 2 HS resources 1 EUL resource 2 R99 resources 5 resources HS R99 R99 DUW20 (5 Resources Id) numHScodesresources=2 numEulresources=1 2 R99 x 128 = 256 CE 63 CE required for A-DCH 256-63 =193 CE for R99 Example 2 HS EUL Example 2: DUW20 6 cc (32 HS users) 2 HS resources 1 EUL resource 2 R99 resources 5 resources HS R99 R99 DUW20 (5 Resources Id) numHScodesresources=2 numEulresources=1 2 R99 x 128 = 256 CE A-DCH: min(2*128*1.3*0.5,32*6*1.3*0.5)= min(165,125)=125 for A-DCH 256-125 =131 CE for R99 Dual carrier Example 4: For Dual Carrier: The two cells involved in the MC connection must be configured in the same HSDPA resource_ID.

Dual duw legacy – mad0226 Dual duw legacy – mad0226 Final comments • In order to make a proper DUW dimensioning, it has to be taken into account: • Number of HS Users per cell • Number of HSDPA Resources • Number of EUL Resources • Number of Carriers per sector • Number of sectors • Number of necessary UL&DL CEs appendix I power parameters • maxDlPowerCapability: The maximum downlink power capability for the cell. The attribute is calculated by the RBS and reported to the RNC. (maxDlPowerCapability = Nominal power (carrier) - ∑ dlattenuation ) • maximumtransmissionpower: This parameter allows the operator to limit the maximum used power in the cell. In normal cases this is not necessary. * 1 carrier node maximumtransmissionpowe r maxTotalOutputPower= 20W Maxdlpowercapabilit y dlattenuatio n appendix I power parameters maxTotalOutputPower= 20W Maxdlpowercapabilit y 1 carrier node dlattenuatio n 2 carriers node maxTotalOutputPower= 40W 20 W 20 W Maxdlpowercapabilit y for F1 cells dlattenuatio n Maxdlpowercapabilit y for F2 cells dlattenuatio n appendix II ce fract dual duw Parameter ul/dlLicFractbbpool2 (DUW same capacity) Fraction (%) of licensed CE assigned to 2nd BaseBandpool CE UL BbPool1 BbPool2 DUW10 DUW10 BbPool1 BbPool2 DUW20 DUW20 BbPool1 BbPool2 DUW30 DUW30 UL 128 128 256 CE UL CE DL 0.5 0.5 UL 384 384 768 CE UL 512 512 1024 DL 128 128 256 CE DL 0.5 0.5 UL ulLicFractBbPool2 DlLicFractBbPool2 50% 50% 0.5 0.5 ulLicFractBbPool2 DlLicFractBbPool2 50% 50% 0.5 0.5 ulLicFractBbPool2 DlLicFractBbPool2 50% 50% DL 384 384 768 CE DL 0.5 0.5 0.5 0.5 768 768 1536 DL *This parameter must be adjusted/optimized depending on the CE consumption per BBPool. appendix II ce fract dual duw Parameter ul/dlLicFractbbpool2 (DUW different capacity) CE UL BbPool1 BbPool2 DUW20 DUW10 UL 384 128 512 DUW10 DUW20 BbPool1 BbPool2 DUW10 DUW30 ulLicFractBbPool2 DlLicFractBbPool2 25% 25% 0.25 0.75 ulLicFractBbPool2 DlLicFractBbPool2 75% 75% DL 128 0.142857 768 0.857143 896 ulLicFractBbPool2 DlLicFractBbPool2 80% 86% UL CE DL DL 384 0.428571 384 0.333333 512 0.571429 768 0.666667 896 1152 ulLicFractBbPool2 DlLicFractBbPool2 57% 67% UL 128 384 512 CE UL BbPool1 BbPool2 DUW20 DUW30 384 128 512 CE DL 0.25 0.75 UL 128 512 640 CE UL DL 0.75 0.25 CE UL BbPool1 BbPool2 CE DL 0.75 0.25 128 384 512 CE DL 0.2 0.8 DL
