APPARATUS AND METHOD FOR TRANSMISSION DIVERSITY USING MORE THAN FOUR ANTENNAS
摘要
There is provided a transmission diversity system. In the case where an MS supporting a different antenna transmission diversity scheme enters the service area of a 4-antenna transmission diversity UTRAN, the UTRAN can transmit pilot signals and common data signals to the MS without the need of modifications to the MS. Therefore, power is distributed among antennas of the UTRAN and system capacity is increased.
