Abstract
The use of the STTD is enabled in a network so that the common channels (CPICH etc.) do not need to be transmitted using transmit diversity, but the STTD can be enabled only for channels having dedicated pilots and which are intended for the UEs supporting this functionality. Other UEs not supporting transmit diversity can use the common channels as usual. In normal transmit diversity operation the UE will use the CPICH transmitted from both antennas as a phase reference. In the proposed method some of the common channels including CPICH are transmitted without transmit diversity even though the STTD is used on channels having dedicated pilots and which are intended for the UEs supporting this functionality.
