Claim 5:
6. The UE of claim 5, wherein the processing circuitry is further configured, for each of the transmissions, to:
map rank indicator (RI) data for the transmission to the same SC-FDMA symbol to which the HARQ ACK/NACK data is mapped, and to pre-DFT symbols that correspond to that same SC-FDMA symbol but that are as far as possible from the DMRS closest in time to the user data of the transmission; or
if two or more SC-FDMA symbols are to carry user data, map rank indicator (RI) data for the transmission to an SC-FDMA symbol that carries user data and that is immediately adjacent in time to the SC-FDMA symbol to which the HARQ ACK/NACK data is mapped, and to pre-DFT symbols that correspond to that adjacent SC-FDMA symbol and that are as close as possible to the DMRS closest in time to the user data of the transmission; or
map rank indicator (RI) data for the transmission to the same SC-FDMA symbol to which map rank indicator (RI) data for the transmission to the same SC-FDMA symbol to which the HARQ ACK/NACK data is mapped, and to pre-DFT symbols that as close as possible to the pre-DFT symbols to which the HARQ ACK/NACK data is mapped, given a predetermined maximum number of pre-DFT symbols allocated to HARQ ACK/NACK data.
