Claim Text:
1. A method of transmitting a data block, comprising: transmitting at least one data block via at least one of at least two downlink frequency bands to a user equipment (UE); receiving a modulation symbol and N spreading sequences via N antenna ports, N being an integer greater than or equal to 2, each of the N spreading sequences being a two-dimensional spreading code, each of the N spreading sequences being received from one antenna port of the N antenna ports and spreading the modulation symbol, and the modulation symbol being received from the N antenna ports; determining acknowledgement/negative acknowledgement (A/N) information in accordance with the modulation symbol and the N spreading sequences, wherein the A/N information indicates whether the at least one data block is correctly detected by the UE, and the modulation symbol and the N spreading sequences jointly determine the A/N information; and determining whether the at least one data block needs to be retransmitted depending on the A/N information.
