Claim 2:
3. The method of claim 1, wherein the method further comprises:
determining, for each of one or more transmissions, whether more than one SC-FDMA symbol of the transmission is to carry user data;
for each of the one or more transmissions in which only one SC-FDMA symbol is to carry user data, mapping rank indicator (RI) data for the transmission to the same SC-FDMA symbol to which the HARQ ACK/NACK data is mapped, but 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; and
for each of the one or more transmissions in which two or more SC-FDMA symbols are to carry user data, mapping RI data for the transmissions 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.
