In the uplink BWP on the uplink carrier 900, the OFDM symbol 920 is mapped to the modulation symbol sequence 910 for PUCCH960, the OFDM symbol 921 is mapped to the modulation symbol sequence 911 for PUCCH960, and the OFDM symbol 922 is mapped to the modulation symbol sequence for PUCCH960. Modulated symbol sequence 912 is mapped. The modulation symbol sequence 910 is generated at least on the basis of applying the cyclic shift 940 to the base sequence 930. The modulation symbol sequence 911 is generated at least on the basis of applying cyclic shift 941 to the base sequence 931. The modulation symbol sequence 912 is generated at least on the basis of applying cyclic shift 942 to the base sequence 932.

The cyclic shift 942 may be determined at least on the basis of the sequence cyclic shift 952. The cyclic shift 940 may be determined based on Equation 5 using at least the sequence cyclic shift 950. The cyclic shift 941 may be determined based on Equation 5 using at least the sequence cyclic shift 951. The cyclic shift 942 may be determined based on Equation 5 using at least the sequence cyclic shift 952.

Mapping the modulation symbol sequence 910 to the OFDM symbol 920 may mean that the modulation symbol sequence 910 is mapped to the first set of resource elements in the OFDM symbol 920. The modulation symbol sequence 911 being mapped to the OFDM symbol 921 may be such that the modulation symbol sequence 911 is mapped to a second set of resource elements in the OFDM symbol 921. The modulation symbol sequence 912 may be mapped to the OFDM symbol 922, or the modulation symbol sequence 912 may be mapped to a third set of resource elements in the OFDM symbol 922. The first set of resource elements, the second set of resource elements, and the third set of resource elements may be different sets of resource elements. At least a part of the first set of resource elements, the second set of resource elements, and the third set of resource elements may be the same set.

For example, the OFDM symbol 920, the OFDM symbol 921, and the OFDM symbol 922 may be continuous with each other. Further, the OFDM symbol 920, the OFDM symbol 921, and the OFDM symbol 922 may be OFDM symbols in different slots.

For example, the base series 930, the base series 931 and the base series 932 may be the same base series. That is, the base series 930, the base series 931 and the base series 932 may include the same group number and the same base series number.

For example, the values of cyclic shift 940, cyclic shift 941, and cyclic shift 942 may be different from each other. The values of the series cyclic shift 950, the series cyclic shift 951, and the series cyclic shift 952 may be different from each other. Further, a part or all of the values of the uplink control information transmitted by the PUCCH 960 may correspond to the values of the series cyclic shift 950, the series cyclic shift 951, and the series cyclic shift 952. That is, a part or all of the values of the uplink control information transmitted by the PUCCH 960 may correspond to the values of the cyclic shift 940, the cyclic shift 941, and the cyclic shift 942.

The modulation symbol sequence 910 may be generated based on Equation 3 using at least the base sequence 920 and the cyclic shift 930.

For example, it is assumed that the value of the uplink control information corresponds to the value of the series cyclic shift. When the uplink control information is 1 bit, the value of the 1 bit is 0 or 1, so that the sequence cyclic shift has at least 2 ¹ = 2 values in order to identify the 0 or 1. Have. When the uplink control information is 2 bits, the values of the 2 bits are {0,0}, {0,1}, {1,1}, {1,0}, so that the sequence cyclic shift is performed. , At least 2 ² = 4 values. That is, when the uplink control information is n bits, the sequence cyclic shift has at least 2 ⁿ possible values. Here, the n is an integer of 1 or more.

The cyclic shift of Equation 5 can have ^NRB _sc = 12 different values. Therefore, when the value of the uplink control information corresponds to the value of the series cyclic shift, the uplink control information does not support 4-bit transmission. For example, means 1, means 2, and means 3 for expanding the correspondence between the value of the uplink control information and the value of the series cyclic shift may be used to solve the above-mentioned problems.

For example, when m _{cs, max} is 12, m _{cs, 950} , and m _{cs, 951} may have 6 different values. Further, the six values may be any of 0, 2, 4, 6, 8, and 10. For example, when m _{cs, max} is 12, m _{cs, 950} , and m _{cs, 951} may have four values. Further, the four values may be any of 0, 3, 6 and 9. For example, when m _{cs, max} is 12, m _{cs, 950} , and m _{cs, 951} may have three kinds of values. Further, the three values may be any of 0, 4, and 8. For the accuracy of cyclic shift detection, _{mcs, max} may be limited. m _{cs, max} may be given by the upper layer parameters. Further, m _{cs and max} may be given by the DCI format. For example, m _{cs, max} may be 12. Further, m _{cs and max} may be 6. Further, m _{cs and max} may be 4. Further, m _{cs and max} may be 3. The means 1 may make a part or all of the values of the uplink control information transmitted by the PUCCH 960 correspond to mcs and _add . Here, m _{cs and add} may be any value from 0 to m _{cs and max} -1. Alternatively, m _{cs and add} may be any value from 1 to m _{cs and max} . That is, m _{cs and add} may have a value equal to or less than m _{cs and max} . For example, when m _{cs and max} are 12, m _{cs and add} may have 6 different values. Further, the six values may be any of 0, 2, 4, 6, 8, and 10. For example, when m _{cs and max} are 12, m _{cs and add} may have four values. Further, the four values may be any of 0, 3, 6 and 9.
