Abstract:
A method for transmitting signals at a User Equipment (UE) in a multi-antenna wireless communication system is discussed. The method includes receiving an uplink grant from a Base Station (BS); transmitting transport blocks and Reference Signals (RSs) for the transport blocks via a plurality of layers based on the uplink grant to the BS; receiving Negative ACKnowledgment (NACK) information for at least one transport block among the transport blocks from the BS; and retransmitting the at least one transport block and the RS for the at least one transport block via at least one layer to the BS.
