The method may comprise the steps of: encoding UCI of K bits, which exceeds 20 bits, and outputting encoded bits of N bits; and mapping on resource elements (RE) in an uplink subframe, without applying an orthogonal cover code (OCC) to the encoded N bits, wherein the uplink subframe may include two symbols, and wherein each symbol may include 12 subcarriers on a frequency axis and six or seven symbols on a time axis. The mapping step may be carried out according to a symbol index and from among symbols remaining after excluding symbols for a demodulation reference signal (DMRS) and a subcarrier index. ## Claims ### Claim at position 1 1-12. (canceled) ### Claim 13 A method for transmitting a physical uplink control channel (PUCCH) signal, the method comprising: transmitting the PUCCH signal using a shortened PUCCH format, wherein the shortened PUCCH format is used if a simultaneous transmission of the PUCCH signal and a sounding reference signal (SRS) is configured in a subframe and if the transmission of the PUCCH signal is partly or fully overlaps with a bandwidth of a cell-specific SRS ### Claim 14 (depends on 13) The method of claim 13, wherein the PUCCH signal includes a hybrid automatic repeat request (HARQ) acknowledgement (ACK). ### Claim 15 (depends on 13) The method of claim 13, wherein the subframe is configured as a cell-specific SRS subframe ### Claim 16 (depends on 13) The method of claim 13, wherein the shortened PUCCH format does not use a last orthogonal frequency division multiplexing (OFDM) symbol in the subframe. ### Claim 17 (depends on 13) The method of claim 13, wherein the PUCCH signal is mapped into resource elements (REs) in increasing order of first frequency indexes and then symbol indexes. ### Claim 18 (depends on 13) The method of claim 13, wherein the shortened PUCCH format is based on a new PUCCH format different from PUCCH formats 1, 1a, 1b and 3. ### Claim 19 A wireless terminal for transmitting a physical uplink control channel (PUCCH) signal, the wireless terminal comprising: a transceiver; a processor configured to control the transceiver thereby performing: transmitting the PUCCH signal using a shortened PUCCH format, wherein the shortened PUCCH format is used if a simultaneous transmission of the PUCCH signal and a sounding reference signal (SRS) is configured in a subframe and if the transmission of the PUCCH signal is partly or fully overlaps with a bandwidth of a cell-specific SRS ### Claim 20 (depends on 19) The wireless terminal of claim 19, wherein the PUCCH signal includes a hybrid automatic repeat request (HARQ) acknowledgement (ACK). ### Claim 21 (depends on 19) The wireless terminal of claim 19, wherein the subframe is configured as a cell-specific SRS subframe ### Claim 22 (depends on 19) The wireless terminal of claim 19, wherein the shortened PUCCH format does not use a last orthogonal frequency division multiplexing (OFDM) symbol in the subframe. ### Claim 23 (depends on 19) The wireless terminal of claim 19, wherein the PUCCH signal is mapped into resource elements (REs) in increasing order of first frequency indexes and then symbol indexes. ### Claim 24 (depends on 19) The wireless terminal of claim 19, wherein the shortened PUCCH format is based on a new PUCCH format different from PUCCH formats 1, 1a, 1b and 3.
