Method and RNC to select a transmission technology when a UE enters the network, which checks whether the EU is MIMO and in that case and if is only available carrier assigns its traffic to said carrier and uses an S-CPICH for providing all traffic MIMO pilot diversity and functional grouping of virtual antennas for a balance. If available more than one carrier, the number of EU, its radio conditions and loading of the carrier is periodically checked. If the carrier is busy only MIMO and its load exceeds the load of the remaining carriers, CPICH diversity STTD is selected; If not and if the EU vulnerable to STTD with good radio conditions only exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network to transmit traffic using STTD MIMO MIMO S-CPICH or vice versa dynamically checking periodically loading and EU criteria a configuration change.
