Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method, a network device and a terminal device for transmitting control information. Background Art

[0002] The current new radio (NR) system can support two types of physical uplink control channels (PUCCH) of different time lengths, namely short-PUCCH and long-PUCCH. Short-PUCCH generally includes 1 or 2 time domain symbols, and long-PUCCH includes 4 to 14 time domain symbols. Both types of PUCCH can carry uplink control information (UCI) of no more than two bits and more than two bits.

[0003] For UCI of no more than two bits, a sequence indication method can usually be used. For example, for ACK / NACK information occupying one bit, two cyclic shifts of the same sequence can be used for indication, but how to determine the cyclic shift value is still a problem to be solved.

[0062] Figure 1 FIG. 1 is a schematic flow chart of a method 100 for transmitting control information according to an embodiment of the present application. The method 100 may be executed by a network device. Figure 1 As shown, the method 100 includes: S110, determining the configuration of an uplink control channel sequence of a terminal device, the configuration of the uplink control channel sequence including at least one of an initial cyclic shift value, a cyclic shift difference value and the number of cyclic shift values; S120, determining at least two cyclic shift values ​​of the uplink control channel sequence according to the configuration of the uplink control channel sequence; S120, determining the UCI sent by the terminal device according to the at least two cyclic shift values.

[0063] It should be understood that the uplink control channel sequence in the embodiment of the present application may be a sequence for carrying control information, and the UCI corresponding to the uplink control channel sequence may include ACK / NACK information, such as hybrid automatic repeat request (HARQ) ACK / NACK information; the UCI corresponding to the uplink control channel sequence may also include an uplink scheduling request (scheduling request, SR), and the UCI corresponding to the uplink control channel sequence may also include channel state information (CSI), but the embodiment of the present application is not limited to this.

[0064] In an embodiment of the present application, a network device determines the configuration of an uplink control channel sequence of a terminal device, and can determine at least two cyclic shift values ​​of the uplink control channel sequence according to the configuration of the uplink control channel sequence. Wherein, the uplink control channel sequence configuration may include an initial cyclic shift value, which may be any one of the at least two determined cyclic shift values; the configuration of the uplink control channel sequence may also include a cyclic shift difference value, which may be: when the at least two cyclic shift values ​​are sorted according to numerical values, the difference between any two adjacent cyclic shift values ​​of the at least two cyclic shift values; the configuration of the uplink control channel sequence may also include the number of cyclic shift values, which may be the number of at least two cyclic shift values, or the number of cyclic shift values ​​may also be greater than the number of the at least two cyclic shift values, and the embodiment of the present application is not limited thereto.

[0065] Optionally, the initial cyclic shift value in the configuration of the uplink control channel sequence can be configured by the network device for the terminal device. Specifically, the network device can configure the same or different initial cyclic shift values ​​for different terminal devices by searching a preset table or other means, and the initial cyclic shift value can be any value in the number of cyclic shifts that the uplink control channel sequence can be. For example, for any terminal device, if the cyclic shift number of the uplink control channel sequence of the terminal device ranges from 0 to 11, any value among the 12 numbers from 0 to 11 can be used as the initial cyclic shift value.

[0066] Optionally, the cyclic shift difference value and / or the number of cyclic shift values ​​in the configuration of the uplink control channel sequence can be determined according to the number of data blocks that the terminal device needs to feedback. For example, assuming that the UCI sent by the terminal device is the ACK / NACK information of at least one data block that needs to be fed back, specifically, when the terminal device needs to feed back the ACK / NACK information of a data block, it can be fed back through 1 bit, and the 1 bit can correspond to two cyclic shift values, and the two cyclic shift values ​​correspond to the ACK information and the NACK information respectively; when the terminal device needs to feed back the ACK / NACK information of two data blocks, it can be fed back through 2 bits, and the 2 bits can correspond to four cyclic shift values, and the four cyclic shift values ​​correspond to the four combinations of ACK / NACK information of each data block respectively, and so on for the ACK / NACK information of other numbers of data blocks. For another example, the network device can also determine the cyclic shift difference value according to the number of cyclic shift values. For example, when there are two cyclic shift values, the cyclic shift difference value is set to 6; when there are four cyclic shift values, the cyclic shift difference value is 3, but the embodiments of the present application are not limited to this.

[0067] Optionally, after the network device determines the configuration of the uplink control channel sequence of the terminal device, it can also send at least one of the configurations of the uplink control channel sequence to the terminal device, so that the terminal device can determine at least two cyclic shift values ​​of the uplink control channel sequence according to the configuration of the uplink control channel sequence, wherein the at least two cyclic shift values ​​have a one-to-one correspondence with at least two states of the UCI, and the terminal device determines the target cyclic shift value corresponding to the target state of the UCI to be sent according to the at least two cyclic shift values, and then determines the target uplink control channel sequence corresponding to the target cyclic shift value, and sends the target uplink control channel sequence to the network device.

[0068] Correspondingly, the network device receives the target uplink control channel sequence sent by the terminal device, determines the configuration of the uplink control channel sequence of the terminal device, and determines at least two cyclic shift values ​​of the uplink control channel sequence according to the configuration of the uplink control channel sequence. The network device detects the received target uplink control channel sequence. Since the target uplink control channel sequence is a sequence of target cyclic shift values ​​among the at least two cyclic shift values ​​adopted by the terminal device, the network device can determine the target cyclic shift value corresponding to the target uplink control channel sequence sent by the terminal device, and then determine the target state of the UCI corresponding to the target cyclic shift value.

[0069] It should be understood that the network device determines the configuration of the uplink control channel sequence, and determines at least two cyclic shift values ​​according to the configuration of the uplink control channel sequence, including: the network device determines at least two cyclic shift values ​​by modulo operation according to the configuration of the uplink control channel sequence. Specifically, the modulo operation can be implemented in the following ways, but the embodiments of the present application are not limited thereto.

[0070] Optionally, as an embodiment, the network device determines at least two cyclic shift values ​​by modulo operation according to the configuration of the uplink control channel sequence, including: determining at least two cyclic shift values ​​according to the size relationship between the initial cyclic shift value and the cyclic shift difference value in the configuration of the uplink control channel sequence within the range of the number of cyclic shifts that the uplink control channel sequence can perform. Specifically, when the initial cyclic shift value is less than the cyclic shift difference value, the sum of the initial cyclic shift value and the integer multiple of the cyclic shift difference value is calculated in sequence within the range of the number of cyclic shifts that the uplink control channel sequence can perform, to obtain the at least two cyclic shift differences. For example, assuming that the initial cyclic shift value is 1, the cyclic shift difference value is 3, and the range of the cyclic shift data that the uplink control channel sequence can perform is 0 to 11, since 1<3, then between 1-11, the sum of 1 and the integer multiple of 3 is calculated in sequence, that is, 1, 1+3*1=4, 1+3*2=7 and 1+3*3=10 are the four cyclic shift values ​​obtained.

[0071] In addition, when the initial cyclic shift value is greater than or equal to the cyclic shift difference value, within the range of the number of cyclic shifts that the uplink control channel sequence can be cyclically shifted, the sum of the initial cyclic shift value and the integer multiple cyclic shift difference value, and the difference between the initial cyclic shift value and the integer multiple cyclic shift difference value are calculated in sequence, and the at least two cyclic shift difference values ​​are obtained together. For example, assuming that the initial cyclic shift value is 8, the cyclic shift difference value is 3, and the range of cyclic shifts that the uplink control channel sequence can be cyclically shifted is 0 to 11, since 8>3, between 1-11, the sum of 8 and integer multiples of 3 is calculated in sequence, that is, 8 and 8+3*1=11 are two of the cyclic shift values, and then the difference between 8 and integer multiples of 3 is calculated in sequence, that is, 8, 8-3*1=5 and 8-3*2=2 are also three of the cyclic shift values, so the four cyclic shift values ​​obtained are 2, 5, 8 and 11 respectively.

[0072] Optionally, as an embodiment, the network device determines at least two cyclic shift values ​​by modulo operation according to the configuration of the uplink control channel sequence, further comprising: the network device determines, according to the above formula (1), an i-th cyclic shift value Φ(i) indicating the two cyclic shift values:

[0073] Φ(i)=(α+i*δ)mod N (1)

[0074] Among them, i is the serial number of the cyclic shift value, i can take values ​​between 0 and the number of cyclic shift values ​​in turn, for example, there are 4 cyclic shift values, then i can take values ​​of 0, 1, 2 and 3 in turn; α represents the initial cyclic shift value, α can be any value within the range of the number of cyclic shifts that the uplink control channel sequence can perform; δ represents the cyclic shift difference; N represents the number of cyclic shifts that the uplink control channel sequence can perform, that is, the number of values ​​within the range of the number of cyclic shifts that the uplink control channel sequence can perform. N can be a protocol agreement or a signaling configuration. The signaling configuration can be explicit or implicit.

[0075] For example, assuming that the network device configures PUCCH resource 1 for the terminal device, the number of cyclic shifts of the uplink control channel sequence of the terminal device can range from 0 to 11, a total of 12 values, that is, N = 12, and the cyclic shift starting value α = 0. When the terminal device needs to feedback 1 bit of ACK / NACK information, it corresponds to two cyclic shift values, that is, i can take 0 and 1 respectively, and the corresponding cyclic shift difference can be set to δ = 6, then Φ(0) = (0+0*6) mod 12 = 0, Φ(1) = (0+1*6) mod 12 = 6, that is, two cyclic shift values ​​0 and 6 are obtained. When the terminal device needs to feed back 2-bit ACK / NACK information, four corresponding cyclic shift values, that is, i can be 0, 1, 2 and 3 respectively, and the corresponding cyclic shift difference can be set to δ=3, then Φ(0)=(0+0*3)mod12=0, Φ(1)=(0+1*3)mod 12=3, Φ(2)=(0+2*3)mod 12=6, Φ(3)=(0+3*3)mod 12=9, that is, four cyclic shift values ​​0, 3, 6 and 9 are obtained.

[0076] For another example, assume that the network device configures PUCCH resource 2 for another terminal device, and the range of the number of cyclic shifts that the uplink control channel sequence of the terminal device can be cyclically shifted is still 0 to 11, a total of 12 values, that is, N = 12, and the cyclic shift starting value α = 9. When the terminal device needs to feedback 1 bit of ACK / NACK information, it corresponds to two cyclic shift values, that is, i can take 0 and 1 respectively, and the corresponding cyclic shift difference can be set to δ = 6, then Φ(0) = (9 + 0 * 6) mod 12 = 9, Φ(1) = (9 + 1 * 6) mod 12 = 3, that is, two cyclic shift values ​​9 and 3 are obtained. When the terminal device needs to feed back 2-bit ACK / NACK information, it corresponds to four cyclic shift values, that is, i can be 0, 1, 2 and 3 respectively, and the corresponding cyclic shift difference can be set to δ=3, then Φ(0)=(9+0*3)mod12=9, Φ(1)=(9+1*3)mod12=0, Φ(2)=(9+2*3)mod12=3, Φ(3)=(9+3*3)mod12=6, that is, four cyclic shift values ​​9, 0, 3 and 6 are obtained.

[0077] Optionally, as an embodiment, the configuration of the uplink control channel sequence may further include a frequency hopping parameter, and the frequency hopping number may be determined according to the frequency hopping parameter. Correspondingly, the network device determines at least two cyclic shift values ​​by modulo operation according to the configuration of the uplink control channel sequence, further comprising: the network device determines, according to the above formula (2), the i-th cyclic shift value Φ(i) indicating the two cyclic shift values:

[0078] Φ(i)=(α+i*δ+h)modN (2)

[0079] Among them, i is the serial number of the cyclic shift value, i can take values ​​between 0 and the number of cyclic shift values ​​in turn, for example, there are 4 cyclic shift values, then i can take values ​​of 0, 1, 2 and 3 in turn; α represents the initial cyclic shift value, α can be any value within the range of the number of cyclic shifts that the uplink control channel sequence can perform; δ represents the cyclic shift difference; N represents the number of cyclic shifts that the uplink control channel sequence can perform, that is, the number of values ​​within the range of the number of cyclic shifts that the uplink control channel sequence can perform, and N can be a protocol agreement or signaling configuration. The signaling configuration can be explicit or invisible; h is the frequency hopping number, h can be a function of the frequency hopping parameter, for example, the frequency hopping parameter can be a time domain identifier t, then h = h(t), optionally, the time domain identifier can be time, can be a number of symbols, can be a subframe number, or other time domain identifiers, the embodiments of the present application are not limited to this.

[0080] For example, it is assumed that the network device configures PUCCH resource 3 for the terminal device, and the number of cyclic shifts of the uplink control channel sequence of the terminal device ranges from 0 to 11, with a total of 12 values, that is, N=12, the cyclic shift starting value α=3, and the frequency hopping value satisfies h(t), where t is the frequency hopping parameter identifying the time domain identifier. When the terminal device needs to feedback 1 bit of ACK / NACK information, two cyclic shift values ​​are corresponding, that is, i can take 0 and 1 in turn, and the corresponding cyclic shift difference can be set to δ=6, then the two cyclic shift values ​​are obtained, namely Φ(0)=(3+0*6+h(t))mod12=(3+h(t))mod12 and Φ(1)=(3+1*6+h(t))mod 12=(9+h(t))mode 12, and if h(t)=2 is calculated, two cyclic shift values ​​5 and 11 are obtained.

[0081] When the terminal device needs to feed back 2-bit ACK / NACK information, four corresponding cyclic shift values, i.e., i can be 0, 1, 2 and 3 respectively, and the corresponding cyclic shift difference can be set to δ=3, then the four cyclic shift values ​​are Φ(0)=(3+0*3+h(t))mod12=(3+h(t))mod12, Φ(1)=(3+1*3+h(t))mod12=(6+h(t))mod12, Φ(2)=(3+2*3+h(t))mod12=(9+h(t))mod12 and Φ(3)=(3+3*3+h(t))mod12=h(t)mod12. If h(t)=1 is calculated, four cyclic shift values ​​are 4, 7, 10 and 1.

[0082] Optionally, as an embodiment, the network device determines at least two cyclic shift values ​​by modulo operation according to the configuration of the uplink control channel sequence, including: the network device obtains at least two cyclic shift values ​​by looking up a table according to the initial cyclic shift value in the configuration of the uplink control channel sequence. Specifically, according to different configurations of the uplink control channel sequence, for example, according to different initial cyclic shift values, at least two cyclic shift values ​​corresponding to each configuration of the uplink control channel sequence are determined, and a table is generated. When the network device determines the initial cyclic shift value, the at least two cyclic shift values ​​corresponding to the initial cyclic shift value can be obtained by looking up the table.

[0083] It should be understood that the range of the number of cyclic shifts that the uplink control channel sequence can perform in the embodiment of the present application can correspond to a physical resource block (PRB). Specifically, for example, the ACK / NACK information included in the UCI can correspond to a PRB, then the uplink control channel sequence can be cyclically shifted within the PRB, and at least two cyclic shift values ​​are determined; for another example, the SR included in the UCI can correspond to another PRB, then the uplink control channel sequence can be cyclically shifted in the other PRB, and at least two cyclic shift values ​​are determined. In addition, the number of combinations of uplink control channel sequences corresponding to the two PRBs is equal to the product of at least two cyclic shift values ​​of the PRB corresponding to the ACK / NACK information and at least two cyclic shift values ​​of the PRB corresponding to the SR.

[0084] For example, the 2-bit ACK / NACK information may correspond to the nth PRB, and four cyclic shift values ​​may be determined within the range of the number of cyclic shifts of the uplink control channel sequence corresponding to the PRB; and the 1-bit SR may correspond to the n+mth PRB, and two cyclic shift values ​​may be determined within the range of the number of cyclic shifts of the uplink control channel sequence corresponding to the PRB, then there are 2*4=8 combinations of sequences corresponding to the two PRBs. Among them, n may be determined by the PUCCH resource configuration indication; m may be obtained based on a predefined rule, for example, the total number of PRBs occupied by PUCCH is N, and m=N+1.

[0085] In an embodiment of the present application, at least two cyclic shift values ​​correspond to at least two states of UCI. Specifically, the state of UCI corresponding to each cyclic shift value can be determined according to the size order of the at least two cyclic shift values, or the state of UCI corresponding to each cyclic shift value can be determined according to the determination order of the at least two cyclic shift values.

[0086] Optionally, according to the size order of at least two cyclic shift values, the state of the UCI corresponding to each cyclic shift value is determined. Specifically, the determined at least two cyclic shift values ​​are sorted according to the size of the numerical values, and correspond to the state of each UCI in order. For example, at least two cyclic shift values ​​are determined by formula (1) or (2), then the at least two cyclic shift values ​​are Φ(0), Φ(1), Φ(2)..., and then in order from small to large, they are Φ(1), Φ(0), Φ(3)..., then according to the size order of the at least two cyclic shift values, at least two states of the UCI correspond.

[0087] For example, for 1-bit ACK / NACK information, the two states of ACK and NACK correspond to two cyclic shift values. Assuming that the cyclic shift value is determined by formula (1) or (2), and the maximum value corresponds to ACK and the minimum value corresponds to NACK, then when the initial cyclic shift value is 3, it is determined that Φ(0)=3, Φ(1)=9, or when the initial cyclic shift value is 9, it is determined that Φ(0)=9, Φ(1)=3, it is determined that 9 corresponds to ACK and 3 corresponds to NACK.

[0088] Optionally, according to the determination order of at least two cyclic shift values, the state of the UCI corresponding to each cyclic shift value is determined. Specifically, the initial cyclic shift value is the first determined cyclic shift value among the at least two cyclic shift values, and the at least two states of the UCI include the first state, and the initial cyclic shift value corresponds to the first state. For example, at least two cyclic shift values ​​are determined by formula (1) or (2), then the determination order of the at least two cyclic shift values ​​is Φ(0), Φ(1), Φ(2)..., and the at least two cyclic shift values ​​correspond to the at least two states of the UCI in this order.

[0089] For example, for 1-bit ACK / NACK information, the two states of ACK and NACK correspond to two cyclic shift values. Assuming that the cyclic shift value is determined by formula (1) or (2), and Φ(0) corresponds to ACK and Φ(1) corresponds to NACK, the corresponding relationship shown in Table 1 can be obtained:

[0090] ACK NACK Rotate value <![CDATA[C inital ]]> <![CDATA[(C inital +6)mod12]]>

[0091] Among them, the cyclic shift difference is 6, C inital is the initial cyclic shift value Φ(0), (C inital +6) mod 12 is Φ(1). For example, when the initial cyclic shift value is C inital =3, it is determined that Φ(0)=3, Φ(1)=9, then 3 corresponds to ACK and 9 corresponds to NACK; and when the initial cyclic shift value is C inital=9, it is determined that Φ(0)=9, Φ(1)=3, then 9 corresponds to ACK and 3 corresponds to NACK.

[0092] For another example, for 2-bit ACK / NACK information, two data blocks correspond to ACK and NACK states respectively, corresponding to four cyclic shift values ​​in total. Assuming that the four cyclic shift values ​​are determined by formula (1) or (2), they are Φ(0), Φ(1), Φ(2) and Φ(3) respectively. The specific corresponding relationship can be shown in Table 2:

[0093] ACK, ACK ACK, NACK NACK, NACK NACK, ACK Rotate value <![CDATA[C inital ]]> <![CDATA[(C inital +3)mod12]]> <![CDATA[(C inital +6)mod12]]> <![CDATA[(C inital +9)mod12]]>

[0094] The two data blocks are the first data block and the second data block. The first state in each cell in the first row of Table 2 corresponds to the first data block, and the second state corresponds to the second data block. For example, "ACK, ACK" means that the first data block is ACK and the second data block is also ACK. The cyclic shift difference is 3, C inital is the initial cyclic shift value Φ(0); (C inital +3) mod 12 is Φ(1), (C inital +6)mod12 is Φ(2), (C inital +9)mod12 is Φ(3).

[0095] For another example, for the case of two PRBs, it is assumed that the two PRBs are the first PRB and the second PRB, wherein the 2-bit ACK / NACK information in the first PRB, the two data blocks correspond to the two states of ACK and NACK respectively, corresponding to a total of four cyclic shift values, assuming that the cyclic shift values ​​are determined by the method such as formula (1) or (2), which are Φ(0), Φ(1), Φ(2) and Φ(3) respectively; the 1-bit SR in the second PRB has two states of positive and negative, then the correspondence between the 2-bit ACK / NACK information in the first PRB and the 1-bit positive SR and negative SR in the second PRB and each cyclic shift value can be shown in the following Table 3:

[0096] Table 3

[0097]

[0098] In the first PBR, the two data blocks are the first data block and the second data block. The first state in each cell in the first row of Table 3 corresponds to the first data block, and the second state corresponds to the second data block. For example, "ACK, NACK" means that the first data block is ACK and the second data block is NACK. The cyclic shift difference is 3, C inital is the initial cyclic shift value Φ(0); (Cinital +3) mod 12 is Φ(1), (C inital +6)mod12 is Φ(2), (C inital +9)mod12 is Φ(3); and the initial cyclic shift value C′ of the SR in the second PRB inital Corresponding to positive SR, another cyclic shift value (C′) corresponding to SR inital +6) mod 12 corresponds to negative SR.

[0099] In this way, the state of the corresponding UCI is determined according to the determination order of at least two cyclic shift values, and the cyclic shift value corresponding to the ACK / NACK information can be adjusted by setting different initial cyclic shift values. Since there may be interference between similar cyclic shift values, this can avoid high-probability states being mapped to similar cyclic shift values. For example, Figure 2 is the result of a more reasonable configuration. Figure 2 It can be seen that A represents ACK information, C represents NACK information, and P represents the probability of the information combination. Therefore, the corresponding cyclic shift value intervals between ACKs in high-probability states of different terminal devices are relatively large.

[0100] Therefore, in the method for transmitting control information of an embodiment of the present application, the network device determines the configuration of the uplink control channel sequence configured by the terminal device, and determines at least two cyclic shift values ​​of the uplink control channel sequence through a modulo operation based on at least one of the initial cyclic shift value, the cyclic shift difference value and the number of cyclic shift values ​​included in the configuration of the uplink control channel sequence, and then determines the UCI indicated by the uplink control channel sequence sent by the received terminal device. In this way, multiple cyclic shift values ​​can be determined using fewer configurations, reducing the configuration set of PUCCH, reducing the physical layer overhead, and also increasing the flexibility of PUCCH resource configuration under limited physical layer indication overhead.

[0101] Combined with the above Figure 1 and Figure 2 The method for transmitting control information according to the embodiment of the present application is described in detail from the perspective of the network device.
