Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, and specifically relates to an uplink transmission method, apparatus and terminal. Background Technology

[0002] The Physical Uplink Control Channel (PUCCH) is a physical channel in the uplink of a New Radio (NR) system used to carry uplink control information. The purpose of setting up the PUCCH is to allow the UE (User Equipment) to transmit Layer 1 or Layer 2 (L1 / L2) uplink control information (UCI), such as channel state reports, Hybrid Automatic Repeat Request (HARQ) acknowledgments, and scheduling requests, when the UE is not scheduled (i.e., not allocated Uplink Shared Channel (ULSCH) resources).

[0003] In related technologies, during uplink transmission, a cyclic shift mechanism is typically used to process the PUCCH sequence to increase user multiplexing capacity. For example, for dedicated PUCCH format (PF)0, up to 6 UEs can be multiplexed (HARQACK is 1 bit) when PUCCH time-frequency resources are the same; as another example, for dedicated PF1, up to 12 UEs can be multiplexed when PUCCH time-frequency resources are the same (considering only frequency domain multiplexing).

[0004] However, for PUCCH of enhanced Physical Resource Block (PRB), its sequence length may change. In this case, if the PUCCH cyclic shift mechanism given in the relevant technology is still used for uplink transmission, the orthogonality of the PUCCH sequence cannot be fully utilized, resulting in low resource utilization. Summary of the Invention

[0024] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0025] like Figure 2 The diagram shown is a flowchart of an uplink transmission method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by a terminal, but is not limited to that executed by a terminal; specifically, it can be executed by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0026] S210, the terminal determines the target PUCCH sequence based on the target cyclic shift value.

[0027] The target cyclic shift value is determined based on the first information.

[0028] The first information includes at least one of the following: the number of resource blocks (RBs) occupied by the PUCCH resource, the number of resource elements (REs) occupied by each RB, and the length of the PUCCH sequence. The PUCCH resource is a resource used to transmit the target PUCCH sequence.

[0029] It is understandable that a PUCCH resource can be used for the transmission of multiple PUCCH sequences, but different PUCCH sequences may correspond to different or the same target cyclic shift value.

[0030] In this embodiment, the format of the PUCCH sequence can be any one of PF0, PF1, PF2, PF3, and PF4, and the sequence type of the PUCCH sequence can be a long sequence or a short sequence, etc. It should be noted that in this embodiment, for different PUCCH sequence formats, PF0 and PF1 refer to sequences of PUCCH format 0 and PUCCH format 1, respectively, and PF4 refers to the demodulation reference signal (DMRS) sequence of PUCCH format 4.

[0031] In one possible implementation, when the PUCCH sequence is an enhanced multi-PRB PUCCH sequence and its sequence type supports a long sequence, its sequence length is the same as the number of REs occupied by the PUCCH sequence.

[0032] Alternatively, when the PUCCH sequence is an enhanced multi-PRB PUCCH sequence and its sequence type supports a short sequence, its sequence length is the same as the number of REs occupied by the PUCCH in one RB, and it can be cyclically shifted between different RBs.

[0033] Alternatively, in the PUCCH sequence of the enhanced multi-PRB PUCCH sequence type, a specific sequence can be supported, and the length of the specific sequence can be divided by the number of REs occupied by the PUCCH sequence, and cyclic shifting can be performed between different sequences.

[0034] S220, the terminal performs uplink transmission based on the target PUCCH sequence.

[0035] In this embodiment, during uplink transmission, the terminal determines a target cyclic shift value based on at least one of the following: the number of RBs occupied by the PUCCH resource, the number of REs occupied by each RB, and the length of the PUCCH sequence. This ensures that the target cyclic shift value corresponds to the length of the PUCCH sequence, thereby fully utilizing the orthogonality of the PUCCH sequence, improving resource utilization, and expanding user reuse capacity.

[0036] like Figure 3 The diagram shown illustrates an uplink transmission method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0037] S310, the terminal determines the second information based on the first information.

[0038] The second information includes at least one of an initial cyclic shift value, a sequence cyclic shift value, and an interval cyclic shift value. The first information includes at least one of the following: the number of Restricted Blocks (RBs) occupied by the PUCCH resource, the number of Receivers (REs) occupied by each RB, and the length of the PUCCH sequence. In other words, the terminal can determine at least one of the following: the number of RBs occupied by the PUCCH resource, the number of REs occupied by each RB, and the length of the PUCCH sequence.

[0039] In this context, the process of determining at least one of the initial cyclic shift value, the sequence cyclic shift value, or the interval cyclic shift value based on the first information will be described below, combining several different implementation methods.

[0040] Method 1: The terminal determines the initial cyclic shift value based on the first information and the first candidate value.

[0041] The first candidate value is determined based on a first PUCCH resource set, which is a resource set used before dedicated PUCCH resource configuration.

[0042] Optionally, the first PUCCH resource set can be implemented by protocol specification, higher-level configuration, or network configuration.

[0043] In this embodiment, the first candidate value determined by the terminal based on the first PUCCH resource set can be one or more. Correspondingly, the initial cyclic shift value determined based on the first candidate value and the first information can be one or more. In this case, considering that there can be multiple first candidate values ​​or initial cyclic shift values, the terminal can select one from multiple first candidate values ​​to calculate the initial cyclic shift value when calculating the target cyclic shift value in the subsequent calculation. Alternatively, the terminal can first calculate multiple initial cyclic shift values ​​based on multiple first candidate shift values, and then select one from the multiple initial cyclic shift values ​​to calculate the target cyclic shift value.

[0044] In one implementation, the terminal may select a first candidate value or an initial cyclic shift value based on received higher-layer signaling (such as Radio Resource Control (RRC) signaling) and / or DCI implicit indications.

[0045] For example, assuming the first PUCCH resource is defined by a protocol and is as shown in Table 1, and the format of the PUCCH sequence is PF0, then the process by which the terminal determines the initial cyclic shift value based on the first information and the first candidate value may include: the network-side device first instructs the terminal via higher-layer signaling that the first candidate value is a set of candidate values ​​in the last column of a certain row in Table 1, such as the set {0, 3, 6, 9} in the last column of the 5th row; then, via DCI signaling, it implicitly instructs the terminal that the first candidate value is a specific position in the set {0, 3, 6, 9}, such as the second position in the set {0, 3, 6, 9}, "3"; finally, the terminal determines the initial cyclic shift value based on the first candidate value "3" indicated by the network side and the first information (such as at least one of the following: the number of RBs occupied by the PUCCH resource, the number of REs occupied by each RB, and the length of the PUCCH sequence).

[0046] As one possible implementation, for the aforementioned method 1, the terminal can use the formula m0 = z1 * N. RB ,or, Calculate the initial cyclic shift value. Where m0 represents the initial cyclic shift value, z1 represents the first candidate value, and N... RB This represents the number of RBs occupied by the PUCCH resource, M*N RE N represents the length of the target PUCCH sequence. RE M represents the number of REs occupied by each RB, and M represents the number of RBs occupied by the target PUCCH sequence.

[0047] It should be noted that the terminal is based on the formula m0 = z1 * N RB When calculating the initial cyclic shift value, all REs in each RB are occupied. Alternatively, the terminal, according to the formula... When calculating the initial cyclic shift value, a portion of the RE in each RB is occupied.

[0048] Table 1

[0049]

[0050] Method 2: The terminal determines the sequence cyclic shift value based on the first information and the second candidate value.

[0051] The second candidate value is determined based on a first mapping relationship, which is either a mapping relationship between Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) information and Scheduling Request (SR) information and the PUCCH sequence, or a mapping relationship between HARQ-ACK information and the PUCCH sequence. In other words, the second candidate value can be determined based on the number of bits of the transmitted HARQ-ACK, the ACK / NACK value, and whether or not an SR is carried.

[0052] In one implementation, the first mapping relationship can be achieved through protocol agreement, higher-level configuration, or network configuration. For example, the first mapping relationship given in this embodiment can be shown in Tables 2-5.

[0053] Table 2

[0054] HARQ-ACK value 0 1 Second candidate value 0 6

[0055] In Table 2, when the value of HARQ-ACK is “0”, the second candidate value is 0; when the value of HARQ-ACK is “1”, the second candidate value is 6.

[0056] Table 3

[0057] HARQ-ACK value {0,0} {0,1} {1,1} {1,0} Second candidate value 0 3 6 9

[0058] In Table 3, when the HARQ-ACK value is “0,0”, the second candidate value is 0; when the HARQ-ACK value is “0,1”, the second candidate value is 3; when the HARQ-ACK value is “1,0”, the second candidate value is 6; and when the HARQ-ACK value is “1,0”, the second candidate value is 9.

[0059] Table 4

[0060] HARQ-ACK value 0 1 Second candidate value 3 9

[0061] In Table 4, when the HARQ-ACK value is “0”, the second candidate value is 3, and when the HARQ-ACK value is “1”, the second candidate value is 9.

[0062] Table 5

[0063] HARQ-ACK value {0,0} {0,1} {1,1} {1,0} Second candidate value 1 4 7 10

[0064] In Table 5, when the HARQ-ACK value is “0,0”, the second candidate value is 1; when the HARQ-ACK value is “0,1”, the second candidate value is 4; when the HARQ-ACK value is “1,0”, the second candidate value is 7; and when the HARQ-ACK value is “1,0”, the second candidate value is 10.

[0065] As one possible implementation, for the aforementioned method 2, the terminal can use formula m CS =z2*N RB ,or, Determine the cyclic shift value of the sequence, where m CS Z represents the cyclic shift value of the sequence, Z2 represents the second candidate value, and N represents the cyclic shift value of the sequence. RB This represents the number of RBs occupied by the PUCCH resource, M*N RE N represents the length of the target PUCCH sequence. RE M represents the number of REs occupied by each RB, and M represents the number of RBs occupied by the target PUCCH sequence.

[0066] It should be noted that the terminal, according to formula m CS =z2*N RB When calculating the cyclic shift value of the sequence, all REs in each RB are occupied. Alternatively, the terminal calculates according to the formula... When calculating the cyclic shift value of the sequence, a portion of the RE in each RB is occupied.

[0067] Method 3: The terminal determines the interval cyclic shift value based on the first information and the first coefficient.

[0068] The first coefficient can be implemented by protocol agreement, high-level configuration, or network-side device configuration, for example, the value of the first coefficient can be 5, etc.

[0069] As one possible implementation, for the aforementioned method 3, the terminal can use formula m int =s*N int Calculate the interval cyclic shift value, where m int This represents the interval cyclic shift value, and s represents the first coefficient. N RB M represents the number of RBs occupied by the PUCCH resource, and N represents the number of RBs occupied by the target PUCCH sequence. int The index represents the target PUCCH sequence.

[0070] Method 4: Determine the initial cyclic shift value based on the first information and the third candidate value, wherein the third candidate value is determined based on the index of the orthogonal sequence and the number of orthogonal sequences.

[0071] In one implementation, the resource set shown in Table 6 can be implemented through protocol agreement, higher-level configuration, or network-side device configuration. This resource set stores multiple third candidate values. In this case, the terminal can determine the third candidate value based on the index and number of orthogonal sequences indicated in the received UE-specific RRC signaling. Specifically, in Table 6... This indicates the number of orthogonal sequences.

[0072] The index of the orthogonal sequence and the number of orthogonal sequences mentioned in Method 4 can be indicated by higher-level signaling.

[0073] It should be noted that, among the four methods for calculating the second information given in this embodiment, the terminal can select one or more of the aforementioned methods to determine the second information based on the format or sequence type of the PUCCH sequence.

[0074] Table 6

[0075]

[0076] S320, the terminal determines the target cyclic shift value based on the second information.

[0077] It is understood that the second information may include at least one of the initial cyclic shift value, the sequence cyclic shift value, and the interval cyclic shift value. That is, the target cyclic shift value may be determined based on at least one of the initial cyclic shift value, the sequence cyclic shift value, and the interval cyclic shift value.

[0078] As one possible implementation, when the terminal determines the target cyclic shift value of the target PUCCH sequence based on the second information, it can also determine the target cyclic shift value of the target PUCCH sequence based on the second information and the third information; wherein, the third information includes at least one of the following: the number of resource blocks (RBs) occupied by the PUCCH resource, the number of resource units (REs) occupied by each RB, and the length of the target PUCCH sequence.

[0079] In this case, the process of determining the target cyclic shift value will be explained below with examples.

[0080] Example 1

[0081] Assuming the PUCCH sequence has the format PF0 and is a long sequence, the number of RBs occupied by the PUCCH resources used to transmit the PUCCH sequence is N. RB And each RB occupies all REs, that is, 12 REs (i.e. If the value is 12), then the target cyclic shift value α of the PUCCH sequence is...l It can be determined by equation (1).

For example, the first candidate value can be all the candidate values ​​in the last column of Table 1. That is, the initial cyclic shift m0 of the PUCCH sequence can be all the candidate values ​​in the last column of Table 1 and the number of RBs N occupied by the PUCCH resources. RB The product of.

[0085] Additionally, the sequence is cyclically shifted m CS It can be calculated according to the aforementioned method 2, wherein the second candidate value can be determined according to Tables 2-5, that is, the sequence cyclic shift value m of the PUCCH sequence. CS The second candidate value can be found in Tables 2-5, along with the number of RBs (N) occupied by the PUCCH resource. RB The product of.

[0086] Example 2

[0087] Assuming the PUCCH sequence is in PF0 format, its length is divisible by the number of REs occupied by the PUCCH, and it is mapped to the allocated PUCCH resources after cyclic shifting between different PUCCH sequences. Each PUCCH resource occupies N... RB There are N RBs, and each RB occupies N REs. RE Therefore, the length of the PUCCH sequence is N. RE *M, then the target cyclic shift value α of the PUCCH sequence l It can be determined by equation (2).

[0088]

[0089] Based on this, the initial cyclic shift m0 of the PUCCH before configuring dedicated PUCCH resources can be calculated according to the aforementioned method 1. For example, the first candidate value can be all the candidate values ​​in the last column of Table 1. That is, the initial cyclic shift m0 of the PUCCH sequence can be the product of all the candidate values ​​in the last column of Table 1. get.

[0090] Additionally, the sequence is cyclically shifted m CS It can be calculated according to method 2, where the second candidate value can be obtained from Tables 2-5, that is, the sequence cyclic shift value m of the PUCCH sequence. CS The second candidate values ​​in Tables 2-5 can be compared with The product of.

[0091] Interval cyclic shift value m int It can be calculated using the aforementioned method 3, such as m int =s*N int ,in The value of s is 5.

[0092] Example 3

[0093] Assuming a PUCCH-DMRS sequence of format 4, and its sequence type is a long sequence, the number of RBs occupied by the PUCCH resources used to transmit the PUCCH sequence is N. RB Each RB occupies the resources of all REs, that is, 12 REs (i.e., If the value is 12), then the target cyclic shift value α of the PUCCH sequence is... l It can be determined by equation (3).

[0096] Based on this, the initial cyclic shift m0 of the PUCCH sequence can be calculated according to the aforementioned method 4. The third candidate value can be determined according to Table 6. That is, the initial cyclic shift m0 of the PUCCH sequence can be the third candidate value in Table 6 and the number of RBs N occupied by the PUCCH resource. RB The product of.

[0097] S330, the terminal determines the target PUCCH sequence based on the target cyclic shift value.

[0098] S340, the terminal performs uplink transmission based on the target PUCCH sequence.

[0099] It is understood that the implementation process of S330 and S340 can be referred to the relevant description in method embodiment 200, and there are no restrictions thereon.

[0100] In this embodiment, the terminal determines at least one of the following: the number of RBs occupied by the PUCCH resource, the number of REs occupied by each RB, and the length of the PUCCH sequence. This enables the expansion of the initial cyclic shift value, the sequence cyclic shift value, and the interval cyclic shift value. Consequently, when the terminal performs cyclic shift on the PUCCH sequence based on the target cyclic shift value calculated from the initial cyclic shift value, the sequence cyclic shift value, and the interval cyclic shift value, it can fully utilize the orthogonality of the PUCCH sequence, improve resource utilization, and expand user reuse capacity.

[0101] like Figure 4 The diagram shown illustrates an uplink transmission method 400 provided in an exemplary embodiment of this application. This method 400 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 400 may include at least the following steps.

[0102] S410, the terminal receives the fourth information sent by the network-side device.

[0103] The fourth information carries at least an initial cyclic shift value, which is the initial cyclic shift determined by the network-side device based on the first information and used to configure dedicated PUCCH resources.

[0104] Alternatively, as a possible implementation, the network-side device can transmit the fourth information via UE-specific RRC signaling.

[0105] It is understood that the process by which the network-side device determines the initial cyclic shift value based on the first information can be referred to the relevant description in method embodiment 300, such as the relevant description in method 1 or method 4. To avoid repetition, it will not be repeated here.

It can be understood that the implementation process of the terminal determining the sequence cyclic shift value and the interval cyclic shift value based on the first information can refer to the relevant description in method embodiment 300, and to avoid repetition, no limitation is made here.

[0109] Based on the descriptions in S410 and S420, the process of determining the target cyclic shift value will be explained below with examples.

[0115] Additionally, the sequence is cyclically shifted m CSIt can be calculated according to the aforementioned method 2, wherein the second candidate value can be determined according to Tables 2-5, that is, the sequence cyclic shift value m of the PUCCH sequence. CS The second candidate value can be found in Tables 2-5, along with the number of RBs (N) occupied by the PUCCH resource. RB The product of.

[0116] Example 5
