Radio base station and method of controlling radio communications |
摘要 |
The present invention provides a radio base station for preventing degradation of transmission quality characteristics even when there are time differences between the instant of channel estimation of uplink time slots UL#1 to UL#N and the instant of transmission of transmission data via downlink time slots DL#1 to DL#N. The radio base station includes transmit diversity controllers 141 to 14N for controlling transmit diversity to be used for downlink time slots DL#1 to DL#N and a data transmitter 15 for transmitting data via downlink time slots DL#1 to DL#N using the controlled transmit diversity.
