The first antenna port and the second antenna port being QCLs in terms of beam parameters may mean that the transmission beam assumed by the receiving side for the first antenna port and the transmission beam assumed by the receiving side for the second antenna port are the same. The terminal device 1 may assume that the two antenna ports are QCLs if the large-scale characteristics of a channel through which symbols are transmitted at one antenna port can be estimated from the channel through which symbols are transmitted at another antenna port. The two antenna ports being QCLs may mean that the two antenna ports are assumed to be QCLs.

[0245] m cs may be used to determine at least the value of the cyclic shift. cs may be referred to as a sequence cyclic shift (also referred to as a sequential cyclic shift). That is, the cyclic shift may be determined based at least on the sequence cyclic shift. cs may be determined based at least on the PUCCH format. cs may correspond to some or all of the values ​​of the uplink control information. For example, in the case of PUCCH format 0, m cs may correspond to some or all of the values ​​of the uplink control information transmitted in the PUCCH corresponding to the PUCCH format 0. cs can be a value between 0 and 11. That is, m cs may correspond to 12 different values ​​of the uplink control information. cs corresponds to some or all of the values ​​of the uplink control information, csThe value of the cyclic shift into which is substituted may correspond to some or all of the values ​​of the uplink control information. That is, the value of the cyclic shift may correspond to some or all of the values ​​of the uplink control information.

[0246] For example, assume that the uplink control information of the PUCCH corresponding to PUCCH format 0 includes HARQ-ACK information. If the HARQ-ACK information is 1 bit and the value of the 1 bit is 0, m cs may be 0. If the value of the bit is 1, m cs may be 6. If the HARQ-ACK information is 2 bits and the value of the 2 bits is {0,0}, m cs can be 0. If the value of the two bits is {0,1}, m cs can be 3. If the value of the two bits is {1,1}, m cs can be 6. If the value of the two bits is {1,0}, m cs can also be 9.

[0247] n cs (n μ s,f , l+l′) may be determined based on Equation 6.

[0248] c(i) may be a pseudo-random sequence, and the i in c(i) may be an index indicating the i-th element of c(i).

[0249] 9 is a diagram illustrating an example in which a modulation symbol sequence for a PUCCH is mapped to a set of resource elements according to one aspect of this embodiment. In FIG. 9, the horizontal axis represents the time domain. In an uplink BWP on an uplink carrier 900, a modulation symbol sequence 910 for a PUCCH 960 is mapped to an OFDM symbol 920, a modulation symbol sequence 911 for a PUCCH 960 is mapped to an OFDM symbol 921, and a modulation symbol sequence 912 for a PUCCH 960 is mapped to an OFDM symbol 922. The modulation symbol sequence 910 is generated at least based on applying a cyclic shift 940 to a base sequence 930. The modulation symbol sequence 911 is generated at least based on applying a cyclic shift 941 to a base sequence 931. The modulation symbol sequence 912 is generated at least based on applying a cyclic shift 942 to a base sequence 932. The cyclic shift 940 may be determined at least based on a sequence cyclic shift 950. The cyclic shift 941 may be determined based at least on the sequence cyclic shift 951. The cyclic shift 942 may be determined based at least on 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.

[0250] Mapping modulation symbol sequence 910 to OFDM symbol 920 may mean mapping modulation symbol sequence 910 to a first set of resource elements in OFDM symbol 920. Mapping modulation symbol sequence 911 to OFDM symbol 921 may mean mapping modulation symbol sequence 911 to a second set of resource elements in OFDM symbol 921. Mapping modulation symbol sequence 912 to OFDM symbol 922 may mean mapping modulation symbol sequence 912 to a third set of resource elements in 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 some 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.

[0251] For example, OFDM symbol 920, OFDM symbol 921, and OFDM symbol 922 may be consecutive to each other, or OFDM symbol 920, OFDM symbol 921, and OFDM symbol 922 may be OFDM symbols in different slots.

[0252] For example, base sequence 930, base sequence 931, and base sequence 932 may be the same base sequence, i.e., base sequence 930, base sequence 931, and base sequence 932 may include the same group number and the same base sequence number.

[0253] For example, the values ​​of cyclic shift 940, cyclic shift 941, and cyclic shift 942 may be different from one another. The values ​​of sequence cyclic shift 950, sequence cyclic shift 951, and sequence cyclic shift 952 may be different from one another. Furthermore, some or all of the values ​​of the uplink control information transmitted in PUCCH 960 may correspond to the values ​​of sequence cyclic shift 950, sequence cyclic shift 951, and sequence cyclic shift 952. That is, some or all of the values ​​of the uplink control information transmitted in PUCCH 960 may correspond to the values ​​of cyclic shift 940, cyclic shift 941, and cyclic shift 942.

[0254] Modulation symbol sequence 910 may be generated based on Equation 3 using at least base sequence 920 and cyclic shift 930. Modulation symbol sequence 911 may be generated based on Equation 3 using at least base sequence 921 and cyclic shift 931. Modulation symbol sequence 912 may be generated based on Equation 3 using at least base sequence 922 and cyclic shift 932.

[0255] The cyclic shift 940 may be determined based on Equation 5 using a sequence cyclic shift 950. The cyclic shift 941 may be determined based on Equation 5 using a sequence cyclic shift 951. The cyclic shift 942 may be determined based on Equation 5 using a sequence cyclic shift 952.

[0256] For example, if the value of the uplink control information corresponds to the value of the sequence cyclic shift, when the uplink control information is 1 bit, the value of the 1 bit is 0 or 1, so in order to distinguish between 0 and 1, the sequence cyclic shift should be at least 2 1 When the uplink control information is 2 bits, the values ​​of the 2 bits are {0,0}, {0,1}, {1,1}, and {1,0}, so the sequence cyclic shift is at least 2 2That is, when the uplink control information has n bits, the sequence cyclic shift has at least 2 n It has three values, where n is an integer of 1 or greater.

[0257] The cyclic shift of Equation 5 is N RB sc = 12 possible values. Therefore, when the value of the uplink control information corresponds to the value of the sequence cyclic shift, the uplink control information does not support 4-bit transmission. For example, means 1, means 2, and means 3 for extending the correspondence between the value of the uplink control information and the value of the sequence cyclic shift may be used to solve the above problem.

[0258] In the means 1, the terminal device 1 may cause some or all of the values ​​of the uplink control information transmitted in the PUCCH 960 to correspond to the difference between the value of the sequence cyclic shift 950 and the value of the sequence cyclic shift 951. In addition, in the means 1, the value of the sequence cyclic shift 950 may also correspond to some or all of the values ​​of the uplink control information transmitted in the PUCCH 960.

[0259] In the method 1, the value of the series cyclic shift 950 is m cs,950 If so, the value m of the sequence cyclic shift 951 cs,951 may be determined based on Equation 7.

number

[0260] m cs,950 is from 0 to m cs,max m can be any value between -1. cs,950 is m cs,max It may have the following values: m cs,951 is from 0 to m cs,max m can be any value between -1. cs,951 is m cs,max It may have the following values: cs,max If is 12, then m cs,950 , and ,mcs,951 may have six different values. The six different values ​​may be any of 0, 2, 4, 6, 8, and 10. For example, m cs,max If is 12, then m cs,950 , and ,m cs,951 may have four different values. The four different values ​​may be any of 0, 3, 6, and 9. For example, m cs,max If is 12, then m cs,950 , and ,m cs,951 may have three values. The three values ​​may be 0, 4, or 8. For the purpose of detecting the cyclic shift with high accuracy, m cs,max may be restricted. m cs,max may be given by higher layer parameters. cs,max may be given by the DCI format. For example, m cs,max may be 12. cs,max may be 6. Also, m cs,max may be 4. Also, m cs,max may be 3. The means 1 may calculate a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 by m cs,add Here, m cs,add is from 0 to m cs,max It can be either -1 or m cs,add is from 1 to m cs,max It can be any value of m cs,add is m cs,max It may have the following values: cs,max If is 12, then m cs,add may have six different values. The six different values ​​may be any of 0, 2, 4, 6, 8, and 10. For example, m cs,max If is 12, then m cs,add may have four different values. The four different values ​​may be any of 0, 3, 6, and 9. For example, m cs,max If is 12, then m cs,add may have three values. The three values ​​may be any of 0, 4, and 8.

[0261] 10 is a diagram illustrating an example in which the value of 4-bit uplink control information according to one aspect of the present embodiment corresponds to a combination of the value of parameter X and the value of parameter Y. X is X max For example, the X max may be 12. max may be 6. max may be 4. max may be 3. The Y may be Y max For example, the Y max may be 12. max may be 6. max may be 4. max may be 3. That is, in FIG. 10, the combination is X max ×Y max The following uplink control information values ​​may be supported:

Furthermore, the value '0110' of the uplink control information may correspond to X=0, Y=6. Furthermore, the value '0111' of the uplink control information may correspond to X=0, Y=7. Furthermore, the value '1000' of the uplink control information may correspond to X=0, Y=8. Furthermore, the value '1001' of the uplink control information may correspond to X=0, Y=9. Furthermore, the value '1010' of the uplink control information may correspond to X=0, Y=10. Furthermore, the value '1011' of the uplink control information may correspond to X=0, Y=11. Furthermore, the value '1100' of the uplink control information may correspond to X=1, Y=0. Furthermore, the value '1101' of the uplink control information may correspond to X=1, Y=1. Furthermore, the value '1110' of the uplink control information may correspond to X=1, Y=2. Furthermore, the value '1111' of the uplink control information may correspond to X=1, Y=3.

[0263] In the first means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are set to m cs,950 and m cs,add That is, the combination may correspond to a combination of m 2 cs,max For example, when part or all of the uplink control information is 4 bits, X is m cs,950 Y may be m cs,add Alternatively, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may be configured from a first part and a second part. In the means 1, the first part may be m cs,950 and m cs,addand the second portion may correspond to m cs,950 and m cs,add It may correspond to.

[0264] In the first means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are set to m cs,950 and m cs,951 That is, the combination may correspond to a combination of m 2 cs,max For example, when part or all of the uplink control information is 4 bits, X is m cs,950 Y may be m cs,951 Alternatively, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may be configured from a first part and a second part. In the means 1, the first part may be m cs,950 and m cs,951 and the second portion may correspond to m cs,950 and m cs,951 It may correspond to.

[0265] FIG. 11 is a diagram illustrating an example in which the value of 4-bit uplink control information according to one aspect of the present embodiment corresponds to a combination of the value of a parameter X′, the value of a parameter Y′, and the value of a parameter Z′. max Y' may have two values. max Z' may have two values. max For example, the Z max may be 12. max may be 6. max may be 4. max may be 3. That is, in FIG. 11, the combination is X max ×Y max ×Z max The following uplink control information values ​​may be supported:

[0266] In FIG. 11 , the value '0000' of the uplink control information may correspond to X'=0, Y'=0, and Z'=0. Furthermore, the value '0001' of the uplink control information may correspond to X'=0, Y'=0, and Z'=1. Furthermore, the value '0010' of the uplink control information may correspond to X'=0, Y'=0, and Z'=2. Furthermore, the value '0011' of the uplink control information may correspond to X'=0, Y'=1, and Z'=0. Furthermore, the value '0100' of the uplink control information may correspond to X'=0, Y'=1, and Z'=1. Furthermore, the value '0101' of the uplink control information may correspond to X'=0, Y'=1, and Z'=2. Furthermore, the value '0110' of the uplink control information may correspond to X'=0, Y'=2, and Z'=0. Furthermore, the value '0111' of the uplink control information may correspond to X'=0, Y'=2, and Z'=1. Furthermore, the value '1000' of the uplink control information may correspond to X'=0, Y'=2, and Z'=2. Furthermore, the value '1001' of the uplink control information may correspond to X'=1, Y'=0, and Z'=0. Furthermore, the value '1010' of the uplink control information may correspond to X'=1, Y'=0, and Z'=1. Furthermore, the value '1011' of the uplink control information may correspond to X'=1, Y'=0, and Z'=2. Furthermore, the value '1100' of the uplink control information may correspond to X'=1, Y'=1, and Z'=0. Furthermore, the value '1101' of the uplink control information may correspond to X'=1, Y'=1, and Z'=1. Furthermore, the value '1110' of the uplink control information may correspond to X'=1, Y'=1, and Z'=2. Furthermore, the value '1111' of the uplink control information may correspond to X'=1, Y'=2, and Z'=0.

[0267] For example, the value of the nth sequence cyclic shift is m cs,cmb (n), a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 is cs,cmb (1) to m cs,cmb (N), where n may be an integer between 1 and N, or N may be an integer greater than 1. That is, m cs,cmb (n) is m cs,cmb,maxIf there are m values, the combination is N cs,cmb,max For example, based on at least the first condition, X may be m cs,cmb (1), and Y is m cs,cmb (2) The first condition may be that part or all of the uplink control information is 4 bits, and that N is 2. For example, based on at least the second condition, X' is m cs,cmb (1), and Y' may be m cs,cmb (2), and Z' is m cs,cmb The second condition may be (3). The second condition may be that part or all of the uplink control information is 4 bits, and N is 3.

[0268] In the first method, the value m of the sequence cyclic shift 952 cs,952 may be determined based on Equation 8.

number

[0269] m cs,952 is from 0 to m cs,max m can be any value between -1. cs,952 is m cs,max It may have the following values: cs,max If is 12, then m cs,952 may have six different values. The six different values ​​may be any of 0, 2, 4, 6, 8, and 10. For example, m cs,max If is 12, then m cs,952 may have four different values. The four different values ​​may be any of 0, 3, 6, and 9. For example, m cs,max If is 12, then m cs,952 may have three values. The three values ​​may be any of 0, 4, and 8. cs,add is m cs,add That is, the means 1 may set a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 to m cs,add and m'cs,add Alternatively, the means 1 may change some or all of the values ​​of the uplink control information transmitted in the PUCCH 960 to m cs,add and m' cs,add It may correspond to the difference between the m cs,add and m' cs,add The difference m cs,add,add may be determined based on Equation 9.

number

[0270] That is, in means 1, the terminal device 1 may correspond some or all of the values ​​of the uplink control information transmitted in PUCCH 960 to a pattern of the difference between the value of sequence cyclic shift 950 and the value of sequence cyclic shift 951, and the difference between the value of sequence cyclic shift 951 and the value of sequence cyclic shift 952.

[0271] For example, the difference between the nth sequence cyclic shift value and the n+1th sequence cyclic shift value is m cs,add In the case of (n), a part or all of the values ​​of the uplink control information to be transmitted by the PUCCH 960 is set to m cs,add (1) to m cs,add It may correspond to a combination of (N-1) values, i.e., m cs,add (n) is m cs,add,max If there are m values, the combination is N-1 cs,add,max Here, n may be an integer between 1 and N, or N may be an integer greater than 1. In addition, when the n-th sequence cyclic shift is sequence cyclic shift 950 and the (n+1)-th sequence cyclic shift is sequence cyclic shift 951, m cs,add (n) is m cs,add For example, based on at least the first condition, X may be determined as m cs,add (1), and Y is m cs,add(2) The first condition may be that part or all of the uplink control information is 4 bits, and N is 3. For example, based on at least the second condition, X' is m cs,add (1), and Y' may be m cs,add (2), and Z' is m cs,add The second condition may be (3). The uplink control information may be partially or entirely 4 bits long, and N may be 4.

[0272] For example, the terminal device 1 may retain information regarding the correspondence between some or all values ​​of uplink control information and parameter sets of PUCCHs. Based on the retained information, the terminal device 1 may transmit a PUCCH using a parameter set associated with some or all values ​​of uplink control information transmitted on the PUCCH. For example, the parameter set may be a combination of parameter X and parameter Y. Also, for example, the parameter set may be a combination of parameter X', parameter Y', and parameter Z'.

[0273] For example, a set of parameters constituting a parameter set may be determined based at least on the number of bits of part or all of the uplink control information transmitted on the PUCCH. th If the number of bits of uplink control information transmitted on the PUCCH is N bits or less, the parameter set may be configured by parameter X and parameter Y. th In the case where the number of bits of part or all of the uplink control information transmitted on the PUCCH exceeds N, the parameter set may be configured by a parameter X', a parameter Y', and a parameter Z'. th If the number of bits of part or all of the uplink control information transmitted on the PUCCH is N bits or less, the number of parameters constituting the parameter set may be a predetermined value (for example, 2). thIf the number of parameters constituting the parameter set exceeds the predetermined value, the number of parameters may be different from the predetermined value.

[0274] For example, the base station device 3 may attempt to detect one or more parameters included in a parameter set from the received PUCCH sequence. Furthermore, the base station device 3 may determine a part or all of the uplink control information associated with the combination of the detected one or more parameters. For example, the one or more parameters may be parameter X and parameter Y. Furthermore, the one or more parameters may be parameter X', parameter Y', and parameter Z'.

[0275] In the means 2, the terminal device 1 may cause some or all of the values ​​of the uplink control information transmitted in the PUCCH 960 to correspond to the difference between the phase of the modulation symbol sequence 910 and the phase of the modulation symbol sequence 911. The difference may be referred to as a phase shift amount. The difference may be referred to as a phase difference.

[0276] In the second means, the modulation symbol sequence 910 is x 910 In the case of (n), the modulation symbol sequence 911x 911 (n) may be determined based at least on Equation 10, where n is the sum of x 910 (n) and x 911 It may also be an index indicating the nth element of (n).

number

[0277] In the means 2, some or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may correspond to the phase shift amount φ. φ may not depend on n in Equation 10. That is, φ may not depend on the subcarrier index for the PUCCH 960. φ may be a function of the index of the OFDM symbol for the PUCCH 960. For example, φ may be a constant multiple of the index of the OFDM symbol. The calculation of Equation 10 is performed by multiplying the sequence x 910It may also mean that (n) is phase shifted by φ.

[0278] In the means 2, the modulation symbol sequence 912 may be generated by shifting the phase of the modulation symbol sequence 911 by φ. Alternatively, the modulation symbol sequence 912 may be generated by shifting the phase of the modulation symbol sequence 910 by Lφ. L may be the number of OFDM symbols between the OFDM symbol 920 and the OFDM symbol 922. For example, when the OFDM symbol 920 and the OFDM symbol 922 are consecutive, L may be 1.

[0279] For example, in the means 2, φ may be determined based on Equation 11, based at least on the fact that φ is a function of the index of the OFDM symbol.

number

[0280] m ps is from 0 to m ps,max -1. That is, m ps is m ps,max It may have two values. ps may be referred to as a phase shift amount index. That is, the phase shift amount may be determined based at least on the phase shift amount index. In Equation 11, l may be an index of an OFDM symbol for the PUCCH 960. In the means 2, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 are calculated based on m ps For example, when the number of bits of a part or all of the value of the uplink control information is N bits, m ps,max is 2 N may be.

[0281] In the second means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are set to m cs,950 and m ps That is, the combination may correspond to a combination of m cs,max ×mps,max For example, when part or all of the uplink control information is 4 bits, X is m cs,950 Y may be m ps Alternatively, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may be configured from a first part and a second part. In the means 2, the first part may be m cs,950 and m ps and the second portion may correspond to m cs,950 and m ps It may correspond to.

[0282] In the second means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are calculated based on the phase shift amount index m corresponding to the modulation symbol sequence 910. ps,910 and the phase shift amount index m corresponding to the modulation symbol sequence 911. ps,911 and the phase shift amount index m corresponding to the modulation symbol sequence 912. ps,912 and m ps,910 is from 0 to m ps,max m can be any value between -1. ps,911 is from 0 to m ps,max m can be any value between -1. ps,912 is from 0 to m ps,max m can be any value between -1. ps,910 is m ps,max It may have the following values: m ps,911 is m ps,max It may have the following values: m ps,912 is m ps,max The phase shift amount φ corresponding to the modulation symbol sequence 910 may have the following values: 910 is at least m ps,910 The phase shift amount φ corresponding to the modulation symbol sequence 911 may be determined based on the following equation. 911 is at least m ps,911 The phase shift amount φ corresponding to the modulation symbol sequence 912 may be determined based on the following equation: 912 is at least m ps,912In the means 2, the modulation symbol sequence 910 may be determined based on at least a base sequence 920, a cyclic shift 930, and φ 910 In the means 2, the modulation symbol sequence 911 may be generated using at least a base sequence 921, a cyclic shift 931, and φ 911 In the means 2, the modulation symbol sequence 912 may be generated using at least a base sequence 922, a cyclic shift 932, and φ 912 and may be generated using

[0283] In the second means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are set to m cs,950 and m ps,910 That is, the combination may correspond to a combination of m cs,max ×m ps,max For example, when part or all of the uplink control information is 4 bits, X is m cs,950 Y may be m ps,910 Alternatively, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may be configured from a first part and a second part. In the means 2, the first part may be m cs,950 and m ps,910 and the second portion may correspond to m cs,950 and m ps,910 It may correspond to.

[0284] In the second means, a part or all of the values ​​of the uplink control information transmitted by the PUCCH 960 are set to m ps,910 and m ps,911 That is, the combination may correspond to a combination of m 2 ps,max For example, when part or all of the uplink control information is 4 bits, X is m ps,910 Y may be m ps,911Alternatively, a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 may be configured from a first part and a second part. In the means 2, the first part may be m ps,910 and m ps,911 and the second portion may correspond to m ps,910 and m ps,911 It may correspond to.

[0285] For example, the nth phase shift index is m ps,cmb (n), a part or all of the values ​​of the uplink control information transmitted in the PUCCH 960 is ps,cmb (1) to m ps,cmb (N), where n may be an integer between 1 and N, or N may be an integer greater than 1. That is, m ps,cmb (n) is m ps,cmb,max If there are m values, the combination is N ps,cmb,max For example, based on at least the first condition, X may be m ps,cmb (1), and Y is m ps,cmb (2). The first condition may be that part or all of the uplink control information is 4 bits, and that N is 2. For example, based on at least the second condition, X' is m ps,cmb (1), and Y' may be m ps,cmb (2), and Z' is m ps,cmb The second condition may be (3). The second condition may be that part or all of the uplink control information is 4 bits, and N is 3.
