METHOD FOR PERFORMING RETRANSMISSION IN MIMO WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
摘要
A method for performing retransmission at a user equipment of a MIMO wireless communication system is disclosed. The method comprises transmitting multiple transport blocks to a base station for a transmission unit time in accordance with uplink grant information, which includes a first new data indicator; receiving ACK/NACK (Acknowledgement/Negative-ACK) responses corresponding to the respective transport blocks and uplink grant information, which includes a second new data indicator, from the base station; and performing new transmission or retransmission for the multiple transport blocks in one transport block unit for a transmission unit time in accordance with the ACK/NACK responses and the second new data indicator, if transport rank is reduced to 1.
