Abstract
Method and RNC for selecting transmission technology when a UE enters the network, which checks whether the UE is MIMO and, if so and only one carrier is available, allocates its traffic to said carrier and uses a S-CPICH to provide all MIMO traffic with a diversity pilot and Virtual Antenna Mapping for balance. If more than one carrier is available, the number of UEs, their radio conditions and load of carriers are checked periodically. If the carrier is busy only with MIMO and its load is higher than the load of the remaining carriers, diversity CPICH of STTD is selected; otherwise and only if the UEs vulnerable to STTD with good radio conditions exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network from transmitting MIMO traffic with STTD to using MIMO with S-CPICH or vice versa dynamically by periodical check of the load and UEs criteria for configuration change.
