Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, terminal, network equipment and storage medium for transmitting uplink control information (UCI). Background Art

[0002] In the fifth generation mobile communication technology (5G, 5th generation mobile networks) New Radio (NR, New Radio), the coverage of uplink service channels and uplink control channels can be enhanced by adopting lower code rates, more repetitions, etc. Here, the uplink control channel carries the following uplink control information: uplink scheduling request indication (SRI, Scheduling Request Indicator), used by the terminal to apply for uplink resource configuration from the base station; acknowledgment / negative acknowledgment (ACK / NACK) feedback information, used by the terminal to reply whether the transmission of downlink service data is correctly received by the terminal; channel state information (CSI, Channel State Indicator), used by the terminal to report the downlink channel status, including the downlink channel rank indication (RI, Rank Indieation), precoding index (PMI, Precoding Matrix Index), channel quality indication (CQI, Channel Quality Indication), etc. Two lengths of PUCCH are supported in the NR system: short PUCCH and long PUCCH. In PUCCH formats 0 to 4, available physical resource blocks (PRBs) of different PUCCH formats are different.

[0003] Table 1 shows the requirements of different PUCCH formats in the NR system for the OFDM symbol length and the number of bits of uplink control information carried.

[0004]

[0005]

[0006] Table 1

[0007] Among them, PUCCH format 0 is used to carry 1 to 2 bits of uplink control information, can transmit 1 or 2 bits of ACK / NACK, and can carry uplink scheduling requests (SR, Scheduling Request). The frequency domain occupies one PRB, and the time domain occupies 1 to 2 symbols. PUCCH format 0 does not use pilots, adopts a sequence of length 12 for transmission, and expresses the combination state of different uplink control information through different cyclic shifts. PUCCH format 1 has a time domain length of 4 to 14 symbols and one PRB in the frequency domain. It is used to carry 1 or 2 bits of uplink control information. DMRS and uplink control information alternate in the time domain and are fixedly mapped to even symbols (the starting symbol index of long PUCCH is 0). The 1 or 2-bit ACK is modulated by binary phase shift keying (BPSK) or quadrature phase shift keying (QPSK) and then multiplied by the sequence. The frequency domain uses cyclic shift and the time domain uses orthogonal cover code (OCC) to increase the multiplexing capacity. PUCCH format2 has a time domain length of 1 to 2 symbols and a frequency domain length of 1 to 16 PRBs. It is used to carry uplink control information greater than 2 bits. The uplink control information uses QPSK modulation, and channel coding and rate matching are performed based on available resources. The OFDM-based waveform is used. The uplink control information and the reference signal frequency division multiplexing (FDM) scheme is used. The DMRS density is 1 / 3, evenly distributed on the 1st, 4th, 7th, and 10th REs. PUCCH format 3 is used to carry a large uplink control information load, with a time domain length of 4 to 14 symbols and multiple PRBs in the frequency domain. It adopts a time division multiplexing (TDM) structure of DMRS and uplink control information, and does not support user multiplexing. The DMRS sequence is the same as that of format 1. The uplink control information is encoded, scrambled, modulated by QPSK or Pi / 2BPSK, and then pre-coded by discrete Fourier transform (DFT) and mapped to the RE that carries the uplink control information. PUCCH format 4 has a time domain length of 4 to 14 symbols and a frequency domain PRB. It carries a moderate uplink control information load size and has a certain multiplexing capacity. It can multiplex 2 or 4 users. The uplink control information is encoded, scrambled, QPSK modulated, and pre-coded and mapped to the RE of the uplink control information.

[0008] It can be seen that only PUCCH format 0 uses sequences to carry uplink control information, and other formats rely on the demodulation reference signal (DMRS) for channel estimation and demodulation. In addition, PUCCH format 0 needs to use a long sequence of at least 12 bits to carry uplink control information, which has low resource utilization and causes high detection complexity when the receiving end performs sequence correlation detection.

[0069] Figure 1 An example of implementing PUCCH transmission based on a sequence in the related art is shown, wherein, taking 10 bits of uplink control information as an example, there are 1024 (2 10 ) different bit values, therefore, at least 1024 sequences are configured in the sequence pool, and each sequence corresponds to each bit value of 10 bits. When transmitting uplink control information, first convert the 10-bit uplink control information into the corresponding decimal value l a , and then select the same sequence as l from the sequence pool aThe corresponding sequence (sequence length is N), and finally the selected sequence is mapped to the N resource elements (RE, Resource Element) of the PUCCH resource to complete the uplink transmission of the uplink control information. The above scheme is completely based on the sequence to realize the transmission of PUCCH, saving the overhead of DMRS, but for the receiving end, the detection complexity is high. For example, for 10 bits of uplink control information, in the above example, correlation detection is required for at least 1024 sequences to determine the transmitted bit. In addition, the increase in the number of bits also leads to the need to find a large number of sequences with good correlation to construct a sequence pool, which increases the difficulty of implementation.

[0070] Based on this, in various embodiments of the present application, the terminal transmits a first sequence combination on a PUCCH resource to carry uplink control information; wherein different values ​​of the uplink control information correspond to different first sequence combinations; the first sequence combination is a set or list or pattern consisting of L elements, the element is one of S sequences, and the sequences of different elements are the same or different; S is an integer greater than or equal to 1; L is an integer greater than or equal to 2, and the network device obtains the first sequence combination based on the OFDM symbol received on the PUCCH; determines the uplink control information corresponding to the first sequence combination, and the use of the first sequence combination in the transmission process of the uplink control information reduces the requirement on the number of sequences, thereby reducing the complexity of sequence correlation detection at the receiving end and improving communication efficiency.

[0071] The present application embodiment provides a method for transmitting uplink control information, which is applied to a terminal, such as Figure 2 As shown, the method includes:

[0072] Step 201: Transmit a first sequence combination on a PUCCH resource; the first sequence combination corresponds to uplink control information.

[0073] Among them, different values ​​of the uplink control information correspond to different first sequence combinations; the first sequence combination is a set or list or pattern consisting of L elements, the element is one of S sequences, and the sequences of different elements are the same or different; S is an integer greater than or equal to 1; L is an integer greater than or equal to 2.

[0074] Here, taking 10 bits of uplink control information as an example, there are 1024 different values ​​of the 10 bits of uplink control information, and these 1024 different values ​​correspond to 1024 different first sequence combinations, wherein each first sequence combination contains at least two elements of the same number.

[0075] The element refers to the constituent unit of the first sequence combination. For example, the first sequence combination is {X1, X2, X2}, where X1 and X2 are two different sequences. Here, "X1, X2, X2" is called a set of sequences or a list of sequences or a pattern composed of sequences, and this set or list or pattern contains 3 elements. For the first sequence combination {X1, X2, X2}, it contains 3 elements, and the sequences corresponding to the second and third elements are the same, that is, the second and third elements both correspond to the sequence "X2". For the first sequence combination {X1, X2, X3}, it also contains 3 elements, but the sequences corresponding to the elements are different.

[0076] Here, each of the L elements is one of the S sequences, so the L elements correspond to at most S sequences. When the L elements are different, L=S, and when there are identical elements, S is less than L.

[0077] In actual applications, when the terminal sends uplink control information, it first determines the first sequence combination corresponding to the uplink control information according to the bit value corresponding to the uplink control information. The terminal completes the transmission of the uplink control information by mapping the L elements in the determined first sequence combination to the PUCCH resources. Mapping the elements to the PUCCH resources means mapping the sequences corresponding to the elements to the PUCCH resources. Since the uplink control information is carried by sequence combinations, when the number of sequences in the sequence pool is constant, the number of sequence combinations obtained based on the sequences in the sequence pool is much larger than the number of sequences in the sequence pool. Therefore, compared with the method of directly using the corresponding sequence to carry the uplink control information, the scheme of the embodiment of the present application greatly reduces the requirements for the number of sequences in the sequence pool. Accordingly, the number of sequences that need to be related detected at the receiving end is also greatly reduced, thereby reducing the detection complexity and improving the transmission efficiency.

[0078] Accordingly, an embodiment of the present application provides a method for transmitting uplink control information, which is applied to a network device, such as Figure 3 As shown, the method includes:

[0079] Step 301: Acquire a first sequence combination based on OFDM symbols received on a PUCCH.

[0080] Step 302: Determine uplink control information corresponding to the first sequence combination.

[0081] Among them, different values ​​of the uplink control information correspond to different first sequence combinations; the first sequence combination is a set or list or pattern consisting of L elements, the element is one of S sequences, and the sequences of different elements are the same or different; S is an integer greater than or equal to 1; L is an integer greater than or equal to 2.

[0082] Here, the network side receives OFDM symbols on the PUCCH, detects the received OFDM symbols, obtains the sequence corresponding to the elements transmitted on the PUCCH, thereby determining the first sequence combination, and then determines the uplink control information corresponding to the received first sequence combination based on the one-to-one correspondence between different values ​​of the uplink control information and different first sequence combinations.

[0083] In practical applications, the terminal determines L elements in the first sequence combination corresponding to the uplink control information based on the candidate N sequences, and constructs the first sequence combination. Accordingly, when the network device performs detection, the received OFDM symbol is subjected to sequence detection based on the N sequences, such as correlation detection, and the detection complexity is greatly reduced. Exemplarily, all sequences in the sequence pool can be numbered, and the terminal and the network device both select sequences numbered 0 to N-1 from the sequence pool.

[0084] Based on this, in one embodiment, the candidate sequences of the S sequences in the first sequence combination include N sequences; N is an integer greater than or equal to S; wherein,

[0085] The N sequences are predefined or configured by the network.

[0086] Here, L elements constituting the first sequence combination are selected from the candidate N sequences, and the number N is related to the construction strategy of the first sequence combination. In practical applications, the N sequences can be configured by the network side to the terminal and the network device respectively, or the terminal and the network device can determine the N sequences according to a predefined method, such as a rule for determining the N sequences given by a protocol.

[0087] Under one construction strategy, the L elements in each first sequence combination are different; under another construction strategy, the L elements in each first sequence combination are allowed to be the same or different.

[0088] In one embodiment, the value of L is predefined or configured by the network, that is, the number of elements in the first sequence combination can be configured by the network side to the terminal and the network device respectively, or can be determined by the terminal and the network device according to a predefined method.

[0089] Taking 10 bits of uplink control information as an example, several examples of construction strategies of the first sequence combination are provided below. It can be understood that in practical applications, the construction strategies of the first sequence combination are not limited to the following examples.

[0090] Example 1:

[0091] Using the combination method, select L elements from N sequences to form the first sequence combination. The sequences corresponding to the L elements in each first sequence combination are different, and the L elements will correspond to S sequences, that is, L = S. In other words, select S sequences from N sequences to obtain the first sequence combination, and you can get For 10 bits of uplink control information, there are 1024 different bit values. That is, assuming that a first sequence combination containing L = S = 4 elements is to be generated, the requirement is The value of is greater than 1024, then N needs to be greater than or equal to 15. When N is equal to 15, That is to say, by taking out sequences corresponding to 4 elements from 15 sequences to form a first sequence combination, a total of 1365 different first sequence combinations can be obtained. By selecting 1024 of these 1365 different first sequence combinations, a one-to-one correspondence between each bit value corresponding to the 10 bits and the first sequence combination can be established.

[0092] Here, 10 bits of uplink control information corresponds to the first sequence combination containing 4 elements. Compared with the requirement of at least 1024 sequences in the related art, only 15 sequences are needed in Example 1 to meet the transmission of uplink control information. Figure 4 , Figure 4 In the example, the candidate sequences are {x1,x2,x3,x4,x5,x6}, the number of candidate sequences is 6, and the number of elements in the first sequence combination is 4, so a total of 15 different combinations can be obtained. Since 3 bits correspond to 8 different values ​​and 4 bits correspond to 16 different values, the 15 sequence combinations containing sequences corresponding to 4 elements obtained from the 6 candidate sequences can be used to carry 3 bits of uplink control information. Figure 4 In the , a one-to-one correspondence between the 3-bit value and the 8 sequence combinations is established. In actual application, according to the value of the 3-bit uplink control information, a sequence combination with a corresponding relationship with the value can be used to carry the 3-bit uplink control information. For example, the value of the uplink control information is "000", and the sequence combination {x1, x2, x3, x4} is used to carry the uplink control information.

[0093] Example 2:

[0094] By using the permutation method, L elements constituting the first sequence combination are selected from N sequences. At this time, the sequences corresponding to the L elements in any first sequence combination are different from each other, and the L elements will correspond to S sequences, that is, L = S. In other words, selecting S sequences from N sequences to obtain the first sequence combination can correspond to Here, the arrangement method is different from the combination method in Example 1. In addition to the information carried by the elements, the order of the elements also carries information. Taking L = 2 as an example, {x1, x2} and {x2, x1} correspond to different element orders and therefore correspond to different first sequence combinations. For 10 bits of uplink control information, there are 1024 different bit values. That is, assuming that a first sequence combination containing 4 elements is to be generated, it is required The value of is greater than 1024, then N needs to be greater than or equal to 8. When N is equal to 8, That is to say, by taking out the sequences corresponding to 4 elements from the 8 sequences and arranging them, a total of 1680 different first sequence combinations can be obtained. By selecting 1024 of these 1680 different first sequence combinations, a one-to-one correspondence between each bit value corresponding to the 10 bits and the first sequence combination can be established.

[0095] Here, corresponding to the case where 10 bits of uplink control information correspond to a first sequence combination containing 4 elements, compared with the sequence quantity requirement of at least 1024 sequences in the related art, only 8 sequences are needed in Example 2 to meet the transmission of the uplink control information.

[0096] Example 3:

[0097] For 10 bits of uplink control information, there are 1024 different bit values. Assume that a first sequence combination containing L = 5 elements is to be generated. Each element in the first sequence combination is selected from N sequences. Each element has N possible selections. Therefore, there are N corresponding values ​​for 5 elements. 5 Different first sequence combinations. Requires N 5 If the value is greater than 1024, then N must be greater than or equal to 4. When N is equal to 4, N 5 =1024, that is, based on the set of 4 sequences, a sequence is selected to form a first sequence combination including 5 elements, where each element is composed of one of the 4 sequences, and a total of 1024 different first sequence combinations can be obtained, so that a one-to-one correspondence between each bit value corresponding to the 10 bits and the first sequence combination can be established. In this case, in the first sequence combination, each element has 4 possible values, and there will be a situation where the sequences corresponding to at least two elements are the same. At this time, S is less than L, and the value of S can be different in different first sequence combinations constructed in this way.

[0098] Here, corresponding to the case where the 10-bit uplink control information corresponds to the first sequence combination containing 5 elements, compared with the sequence quantity requirement of at least 1024 sequences in the related art, only 4 sequences are needed in Example 3 to meet the transmission of the uplink control information.

[0099] In one embodiment, the different first sequence combinations include the following situations:

[0100] The L elements contained in the first sequence combination are not completely identical; or,

[0101] The arrangement order of the L elements included in the first sequence combination is not completely the same.

[0102] Here, the first sequence combination is one of a first number of different first sequence combinations; among the first number of different first sequence combinations, assuming that the first number is n and the bit length of the uplink control information is m, then the value of n can be greater than or equal to 2 m That is, the first sequence combination corresponding to the m-bit uplink control information is at least 2 m One of different first sequence combinations. For example, 10 bits of uplink control information corresponds to 1024 different values, so it is necessary to support the construction of at least 1024 different first sequence combinations. Among the first number of different first sequence combinations, the L elements contained in any two first sequence combinations are not exactly the same, or the L elements contained in any two first sequence combinations may be exactly the same, but the arrangement order of the L elements is not exactly the same. In combination with the above examples, the L elements contained in any two first sequence combinations in Example 1 are not exactly the same, and the L elements contained in any two first sequence combinations in Example 2 may be the same, but the arrangement order of the L elements is not exactly the same.

[0103] It should be noted that, here and in other examples, different cyclic shifts are also considered as different sequences. Specifically, different cyclic shift sequences of the same base sequence are also considered as different sequences.

[0104] In actual application, the OFDM symbol on the PUCCH resource is used to carry the first sequence combination corresponding to the uplink control information. For example, corresponding to the first sequence combination containing L elements, L OFDM symbols on the PUCCH resource are used to carry the first sequence combination, and each OFDM symbol carries one element in the first sequence combination.

[0105] When mapping elements to OFDM symbols, corresponding to Example 1 above, since the combination method does not need to consider the sequence order, the 15 candidate sequences can be ordered and numbered 0 to 14 in sequence. When transmitting, the sequences corresponding to the 4 elements in the first sequence combination are mapped to the 4 OFDM symbols of the PUCCH resource in the order of small to large numbers. In this way, the receiving end performs correlation detection on the OFDM symbols received on the PUCCH one by one. After determining the sequence on the first OFDM symbol, for the second OFDM symbol, it only needs to detect the sequences with a larger number than the sequence number corresponding to the first OFDM symbol in the 15 candidate sequences. For the third OFDM symbol, it only needs to detect the sequences with a larger number than the sequence number corresponding to the second OFDM symbol in the 15 candidate sequences. For the fourth OFDM symbol, it only needs to detect the sequences with a larger number than the sequence number corresponding to the third OFDM symbol in the 15 candidate sequences. In the above manner, the complexity of the receiving end performing correlation detection on the OFDM symbol can be greatly reduced. Corresponding to Example 2 above, since the arrangement method needs to consider the order of the sequences, the four sequences in the first sequence combination are mapped to the four OFDM symbols of the PUCCH resources in sequence according to the order of arrangement.

[0106] In practical application, for each of the L elements in the first sequence combination, multiple OFDM symbols may be used to carry the corresponding element. Based on this, in one embodiment, when the first sequence combination is transmitted on the PUCCH resource, the method includes:

[0107] Each element of the L elements is mapped to M OFDM symbols of the PUCCH resource for transmission; M is an integer greater than or equal to 1.

[0108] Here, corresponding to the L elements in the first sequence combination, each sequence is transmitted using one or more than one OFDM symbol.

[0109] In one embodiment, the length of an element is the length of M OFDM symbols.

[0110] That is, the length of the M OFDM symbols corresponds to the number of REs contained in the M OFDM symbols.

[0111] Here, for an element in the first sequence combination whose length is M OFDM symbols, the element is carried by M OFDM symbols. Each element in the first sequence combination can be determined according to the strategies in Examples 1 to 3. The following is a corresponding implementation example:

[0112] Example 4:

[0113] For 10 bits of uplink control information, there are 1024 different bit values. Assuming that there are 12 OFDM symbols in the PUCCH resource, the first sequence combination contains L=2 elements: element 1 and element 2. Different combinations or different arrangements of element 1 and element 2 are used to carry different uplink control information. The length of each element is 6 OFDM symbols. Then the first 6 OFDM symbols in the PUCCH resource are used to carry element 1, and the last 6 OFDM symbols are used to carry element 2. Here, assuming that there are 32 candidate sequences, refer to the strategy of Example 3. The first 6 OFDM symbols select sequences from the sequence pool, and there are 32 choices. The last 6 OFDM symbols select sequences from the sequence pool, and there are also 32 choices. Therefore, there are 32*32=1024 possibilities, corresponding to 1024 first sequence combinations. The 1024 first sequence combinations are matched one by one with the 1024 different bit values, so 10 bits of uplink control information can be carried by 2 elements on 12 OFDM symbols. Of course, the first sequence combination may also be determined by referring to Examples 1 and 2. The length of the M OFDM symbols corresponds to the number of REs contained in the M OFDM symbols.

[0114] In Example 4, corresponding to the case where 10 bits of uplink control information correspond to a first sequence combination containing 2 elements, compared with the sequence quantity requirement of at least 1024 sequences in the related art, only 32 sequences are needed to meet the transmission of the uplink control information.

[0115] In one embodiment, when M is greater than 1, when each of the L elements is mapped to M OFDM symbols of a PUCCH resource for transmission, the method includes:

[0116] The elements are repeatedly mapped to M OFDM symbols for transmission; wherein,

[0117] The M OFDM symbols to which the element is repeatedly mapped are continuous; or,

[0118] The M OFDM symbols to which the elements are repeatedly mapped are spaced.

[0119] In one embodiment, the M values ​​corresponding to different elements in the first sequence combination are the same; or,

[0120] At least two elements in the first sequence combination correspond to different M values.

[0121] Here, assuming that the number of OFDM symbols on the PUCCH resource is greater than the number of OFDM symbols required to carry the first sequence combination, then it is possible to consider repeating the transmission of all or part of the elements in the first sequence combination on the remaining OFDM symbols. For example, there are 14 OFDM symbols on the PUCCH resource, and the 4 elements in the first sequence combination are mapped one by one to the 1st to 4th OFDM symbols, and then the 4 elements in the first sequence combination are repeatedly mapped to the 5th to 8th OFDM symbols and the 9th to 12th OFDM symbols. At this time, there are still the remaining 13th and 14th OFDM symbols, then the first 2 elements in the first sequence combination can be remapped to the 13th and 14th OFDM symbols. Through the above-mentioned repeated transmission method, the reliability of uplink control information transmission can be improved, and the receiving end can be guaranteed to receive the uplink control information to a greater extent.

[0122] In actual application, each element in the first sequence combination can be repeatedly mapped to M consecutive OFDM symbols, or, can also be repeatedly mapped to M spaced OFDM symbols. The M OFDM symbols to which the elements are repeatedly mapped are spaced, and can be evenly spaced or non-uniformly spaced. Moreover, each element in the first sequence combination can be mapped to M OFDM symbols, or, the M values ​​corresponding to at least two elements in the first sequence combination are different. For example, in the above example, the first two elements in the first sequence combination are repeatedly mapped to 4 OFDM symbols, and the last two elements are repeatedly mapped to 3 OFDM symbols.

[0123] It should be noted that, here, the length of the element corresponds to the length of a single OFDM symbol in the PUCCH resource, that is, corresponds to the number of REs in a single OFDM symbol.

[0124] Combination Figure 5For example, the uplink control information corresponds to the first sequence combination {x1, x2, x3, x4}. When mapping the uplink control information to OFDM symbols, mapping mode 1 can be used, that is, after mapping the first sequence combination once on consecutive OFDM symbols, the first sequence combination is repeatedly mapped again, so that each element is mapped to 3 OFDM symbols evenly spaced; mapping mode 2 can also be used, that is, the first element in the first sequence combination is repeatedly mapped 3 times on consecutive OFDM symbols, and then the second element in the first sequence combination is repeatedly mapped 3 times on consecutive OFDM symbols, and so on, until each element completes 3 times of repeated mapping, in which case each element can be repeatedly mapped to 3 consecutive OFDM symbols. In actual application, for mapping mode 1, when the number of OFDM symbols of the PUCCH resource and the number of elements in the first sequence combination are not integer multiples, there is a situation where the M value corresponding to some elements is 1 less than the M value corresponding to other elements, that is, the number of repeated mappings of some elements is 1 less than the number of repeated mappings of other elements.

[0125] In the related art, for LTE's PUCCH format 1 or PUCCH format 2, a sequence with a length of 12 is obtained by multiplying the modulated symbol with a sequence with a length of 12 to obtain a sequence with a length of 12 after spreading. For PUCCH format 1, one LTE subframe includes 14 OFDM symbols. When DMRS occupies 3 symbols in each time slot, PUCCH occupies 4 symbols in each time slot. Therefore, the modulated symbol is spread on the 4 symbols using different cyclic shifts of the same base sequence with a length of 12, and further spread in the time domain using a sequence with a length of 4 (for conventional CP) to other symbols except the DMRS symbol. For PUCCH format 2, the 10 modulated symbols are spread using different cyclic shift sequences of the same sequence and mapped to 10 OFDM symbols. Therefore, regardless of PUCCH format 1 or PUCCH format 2, the modulation symbols carrying uplink control information are spread using a sequence of length 12, and the sequences spread on different symbols are phase rotated (corresponding to different cyclic shifts), rather than carrying the uplink control information by selecting a sequence. Figure 6 and Figure 7 The structures of PUCCH format 1 and PUCCH format 2 in the normal CP are shown respectively. In the solution of the present application, the corresponding sequence combination is selected through the uplink control information, that is, different sequence combinations carry different uplink control information.

[0126] In addition, in the related art, a corresponding long sequence is selected for transmission through uplink control information (the length of the sequence corresponds to the number of REs in the PUCCH resource). The long sequence is taken from a sequence pool with a total of N sequences. Different uplink control information corresponds to different long sequences. For example, a 10-bit UCI has a total of 1024 value states, and 1024 sequences are required to distinguish different states. The receiving end performs sequence correlation detection and matches the sent sequence, so that the sent information bits can be identified. The solution of the embodiment of the present application is to carry different uplink control information through different sequence combinations, that is, different uplink control information corresponds to different sequence combinations. Here, the sequence combination is composed of at least 2 elements, and different elements or different ordering of elements correspond to different sequence combinations, which can be used to carry different uplink control information.
