DUAL CODEWORD RE-TRANSMISSION

摘要

The present invention addresses apparatuses, methods and computer program product for providing enhanced codeword re-transmission for multi-codeword in 4 antenna branch HSDPA MIMO wireless communication network, thereby preventing getting stuck in higher than rank 1transmissions. When a negative acknowledgement signaling is received from a terminal upon transmission comprising a first and a second codeword to the terminal, the codeword not associated with the negative acknowledgement signaling is replaced with a temporary codeword, and a transmission a re-transmission of the codeword associated with the negative acknowledgement signaling and the temporary codeword to the base station is caused.
