In RAN E/// there is this parameter called cellRange. You need to set this parameter greater than 30000 mts
To make it greater than 35000 mts you need to activate a feature called extended range (same as in GSM)
In the 3GPP standard, the limitations which impose restrictions on WCDMA cell range (size) are in the network protocols. Currently the Propagation Delay IE is limited to 60 km ( as dd said)
