[0033] The transmission method of the uplink control channel provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0034] like Figure 2 As shown, one embodiment of the present invention provides an uplink control channel transmission method 200, which can be executed by a terminal device; in other words, the method can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0035] S202: The target terminal UE receives the target configuration information.

[0036] The target configuration information includes: N and L candidate PUCCH resources.

[0037] Wherein, N is the number of PRBs available for at least one UE in the target cell to transmit PUCCH. The L candidate PUCCH resources are the L candidate PUCCH resources available for at least one UE in the target cell to transmit PUCCH. The target cell is the cell where the target UE resides.

[0038] S204: Determine the actual number M of PRBs sent for PUCCH.

[0039] In some cases, the base station configures the number of PRBs for the shared PUCCH at the cell level, possibly based on the worst coverage scenario within the cell. The UE may not need such a large number of PRBs to meet coverage requirements. In this step, the UE can choose the actual number of PRBs to send for the PUCCH based on its own circumstances. M ≤ N, meaning the UE can meet coverage requirements with a number of PRBs less than the one configured by the base station.

[0040] S206: Determine the positions of the M actual PRBs for sending PUCCH.

[0041] S208: Send PUCCH at the locations of the M actual PRBs.

[0042] The uplink control channel transmission method provided in this embodiment of the invention involves receiving target configuration information through a target terminal UE. The target configuration information includes: N physical resource blocks (PRBs) available for at least one UE in the target cell to transmit the Physical Uplink Control Channel (PUCCH), and L candidate PUCCH resources available for at least one UE in the target cell to transmit the PUCCH. The target cell is the cell where the target UE is located. The method further involves determining the actual number of PRBs (M) for transmitting the PUCCH, where M ≤ N; determining the locations of the M actual PRBs for transmitting the PUCCH; and transmitting the PUCCH at the locations of the M actual PRBs, enabling the UE to meet coverage requirements with a smaller number of PRBs.

[0043] Furthermore, the UE may or may not have the capability to transmit multiple PRB PUCCHs (multi-Physical Resource Block Physical Uplink Control Channel). The uplink control channel transmission method provided in this embodiment of the invention can meet the transmission requirements of UEs that do not have the capability to transmit multiple PRB PUCCHs.

[0044] In one implementation, S204: Determine the actual number M of PRBs sent for the PUCCH, including:

[0045] Determine the actual number M of PUCCHs sent based on at least one of the following:

[0046] The target UE's ability to send PUCCH;

[0047] The power class type of the target UE;

[0048] The format of the PUCCH sent by the target UE;

[0049] Path loss between the target UE and the base station;

[0050] The power of the target UE transmitting the Physical Random Access Channel (PRACH);

[0051] The number of bits of uplink control information (UCI) carried in the PUCCH transmitted by the target UE;

[0053] Base station display indicators;

[0054] Implicit indications of the base station.

[0055] The capability of multiple PRB PUCCHs is optional for some UEs. When the actual number M of PRBs to be sent is determined based on the target UE's ability to send PUCCHs, M satisfies at least one of the following:

[0056] If the target UE has the capability to transmit multiple PRB PUCCHs, then M is equal to N;

[0057] If the target UE does not have the ability to send multiple PRB PUCCHs, then M equals 1;

[0058] If the target UE has the capability to send a PUCCH of up to Z PRBs and Z is greater than or equal to N, then M is equal to N;

[0059] If the target UE has the PUCCH capability to send up to Z PRBs and Z is less than N, then M is equal to Z;

[0060] If the target UE has the capability to send a PUCCH containing Zi PRBs, then M is equal to Zi, where Zi is at least one of Z1, Z2…ZK, and Zi<=N. <Zi+1,1<=Z1<Z2<…<ZK,ZK> N;

[0061] If the target UE has the capability to send PUCCHs containing Zi PRBs, then M is equal to ZK, where ZK ≤ N, and Zi is at least one of Z1, Z2…ZK, 1 <= Z1 <Z2<…<ZK。

[0062] In one implementation, M equals K when at least one of the following first conditions is met; wherein the first condition includes:

[0063] The target UE's Power class type is Type 1;

[0064] The base station instructs the target UE to limit the format of the PUCCH to the first format;

[0065] The path loss between the target UE and the base station is greater than a first threshold, which is determined by the protocol or configured by the base station.

[0066] The path loss between the target UE and the base station is less than a first threshold, which is determined by the protocol or configured by the base station.

[0067] The target UE transmits PRACH with a power greater than a second threshold, which is determined by the protocol or configured by the base station;

[0068] The target UE transmits PRACH at a power less than a second threshold, which is determined by the protocol or configured by the base station;

[0069] The number of UCI bits carried by the PUCCH sent by the target UE is greater than a third threshold, which is agreed upon by the protocol or configured by the base station;

[0070] The number of UCI bits carried by the PUCCH sent by the target UE is less than a third threshold, which is agreed upon by the protocol or configured by the base station;

[0071] The code rate of the PUCCH sent by the target UE is greater than the fourth threshold, which is agreed upon by the protocol or configured by the base station;

[0072] The code rate of the PUCCH sent by the target UE is less than the fourth threshold, which is agreed upon by the protocol or configured by the base station;

[0073] The base station indicates that the DCI of the PUCCH resource is limited to the first control resource set;

[0074] The base station indicates that the DCI of the PUCCH resource is limited to the first search space;

[0075] The PUCCH resources indicated by the base station are limited to the first set.

[0076] Wherein, the first threshold, the second threshold, the third threshold, the fourth threshold, the first control resource set, the first search space, the first format, the first type, and the first set are specified by the protocol or configured by the base station, and the first format, the first type, the first control resource set, the first search space, and the first set include, but are not limited to, one.

[0077] The K satisfies one of the following:

[0078] Protocol predefined;

[0079] Base station configuration;

[0080] Target UE reporting;

[0081] It depends on the value achieved by the target UE.

[0082] Therefore, the UE can choose the number of PRBs to actually send for the PUCCH based on its own capabilities or circumstances. For example, if the UE does not have the "multi-PRB PUCCH" capability, if the UE has the "multi-PRB PUCCH" capability but the protocol allows the UE to optionally send "multi-PRB PUCCH" or "1-PRB PUCCH", or if the protocol allows the UE to determine the number of PRBs to actually send for the PUCCH, the UE can choose the number of PRBs to actually send for the PUCCH based on its own capabilities or circumstances.

[0083] like Figure 3 As shown, one embodiment of the present invention provides an uplink control channel transmission method 300, which can be executed by a terminal device; in other words, the method can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0088] S306: Based on the first indication value, determine a first PUCCH resource from the L candidate PUCCH resources, wherein the first PUCCH resource includes N target PRBs.

[0089] Specifically, the first indicator value r PUCCH Satisfying 0≤rPUCCH ≤15,

[0090]

[0091] Where, Δ PRI For the PUCCH resource index indication field in the downlink control information (DCI) received by the UE, N CCE n is the number of Control Channel Elements (CCEs) in the Control Resource Set (CORSET) of the Physical Downlink Control Channel (PDCCH) where the DCI received by the UE resides. CCE,0 This is the first CCE index of PDCCH.

[0100] The second PRB is: when the PUCCH sent by the target UE is configured with frequency hopping, at least one PRB among the M PRBs of the second hop of the PUCCH sent by the target UE. For example, the PRB with the largest index among the M PRBs of the second hop configured with frequency hopping, the PRB with the smallest index among the M PRBs of the second hop configured with frequency hopping, the PRB with an index of the middle value among the M PRBs of the second hop configured with frequency hopping, and the PRB with an index of a specific value among the M PRBs of the second hop configured with frequency hopping.

[0146] Examples 1 and 2 are given below for illustration.

[0147] Example 1

[0148] like Figures 4b-4c As shown in Table 1, in S402, the base station uses a System Information Block (SIB), such as SIB1, to indicate that the number N of PUCCH PRBs sent by all UEs in the cell where UE1 resides is 2. The base station uses pucch-ResourceCommon to indicate that the row index of the cell where UE1 resides is 1. Different padding in the figure below represents different PUCCH time-frequency resources. The same PUCCH time-frequency resource can also correspond to different cyclic shifts. The figure corresponds to a total of 16 different PUCCH resources.

[0149] Table 1

[0150]

[0151] The base station provides DCI instructions, and UE1 obtains the corresponding r. PUCCH =6, the time-frequency resources of the corresponding first PUCCH resource are as follows Figure 4b middle Partially, the cyclic shift is r PUCCH Mod 3 = 0 corresponds to the cyclic shift with index 0 in the cyclic shift set {0, 4, 8}: 0. Each cell in the diagram can represent one PRB. The diagram includes the frequency domain location of a bandwidth part (BWP), which can be understood as not showing all PRBs in the diagram, but rather some PRBs that are not shown.

[0152] UE1 lacks the capability to send multi-PRB PUCCH. In S407, UE1 reports to the base station that it lacks this capability through the PRACH resources configured by the base station. The base station has configured frequency hopping for the PUCCH. The first hop resource of the PUCCH is the PRB with the smallest first hop index of the first PUCCH resource. The second hop resource of the PUCCH is the PRB with the largest second hop index of the first PUCCH. Therefore, in S406, UE1 actually sends the following PUCCH resources: Figure 4c middle Partial. The base station detects PUCCH in this part.

[0153] Example 2

[0154] Combined again Figures 4b-4c As shown in Table 1, in S402, the base station indicates through SIB1 that the number of PRBs sent by all UEs in the cell where UE1 is located is 2. The base station indicates through pucch-ResourceCommon that the row index of the cell where UE1 is located is 1. Different padding in the figure represents different PUCCH time-frequency resources. The same PUCCH time-frequency resource can also correspond to different cyclic shifts. There are a total of 16 different PUCCH resources in the figure.

[0155] The base station provides DCI instructions, and UE1 obtains the corresponding r. PUCCH =6, the time-frequency resources of the corresponding first PUCCH resource are as follows Figure 4b middle Partially, the cyclic shift is r PUCCH mod 3 = 0 corresponds to the cyclic shift with index 0 in the cyclic shift set {0, 4, 8}: 0.

[0156] In S404, UE1 determines the number of PRBs for the transmitted PUCCH to be 1 by judging whether the power class is the first type restricted by the base station and whether the path loss between the UE1 and the base station is greater than a first threshold. UE1 then reports the number of PRBs for the transmitted PUCCH to the base station through the PRACH resources configured by the base station.

[0157] The base station has configured frequency hopping for the PUCCH, and the minimum PRB index for the first hop of the PUCCH is... The minimum PRB index for the second hop of PUCCH is P1 and P2 are the minimum index of the first-hop PRB and the maximum index of the second-hop PRB in the first PUCCH resource. Q1 and Q2 are the minimum index of the first-hop PRB and the minimum and maximum PRB indices of the second-hop PRB in the first PUCCH resource. Therefore, in S406, UE1 actually sends the following PUCCH resource: Figure 4c middle Partial. The base station detects PUCCH in this part.

[0158] Example 3

[0159] Combined again Figures 4d-4e As shown in Table 1, in S402, the base station indicates through SIB1 that the number of PRBs sent by all UEs in the cell where UE1 is located is 4. The base station indicates through pucch-ResourceCommon that the row index of the cell where UE1 is located is 1. Different padding in the figure represents different PUCCH time-frequency resources. The same PUCCH time-frequency resource can also correspond to different cyclic shifts. There are a total of 16 different PUCCH resources in the figure.

[0160] The base station provides DCI instructions, and UE1 obtains the corresponding r. PUCCH =6, the time-frequency resources of the corresponding first PUCCH resource are shown in the figure. Partially, the cyclic shift is r PUCCH mod 3 = 0 corresponds to the cyclic shift with index 0 in the cyclic shift set {0, 4, 8}: 0.

[0161] In S404, UE1's capability is to transmit a PUCCH with a maximum of 2 PRBs. UE1 determines the number of PRBs M for the transmitted PUCCH to be 2 by judging whether the power of the PRACH is greater than a second threshold. UE1 reports the number of PRBs for the transmitted PUCCH to the base station via msg3.

[0162] The base station configures frequency hopping for the PUCCH, and the minimum PRB index of the first hop of the PUCCH is Q1 = P1 + (r PUCCH,index The minimum PRB index of the second hop in the PUCCH is Q2 = P2 - (r) * M. PUCCH,index Let N = (mod N) * M, where P1 and P2 are the minimum PRB index of the first hop PRB in the first PUCCH resource and the maximum PRB index of the second hop PRB. Q1 and Q2 are the minimum index of the first hop PRB in the first PUCCH resource and the minimum and maximum PRB indices of the second hop PRB. The N PRB resources of the first PUCCH resource correspond to multiple r... PUCCH Constitute the set {r PUCCH,0 ,r PUCCH,1 ...r PUCCH，X-1}, where X is the r corresponding to the first PUCCH resource. PUCCH The number of elements. The corresponding r in the set. PUCCH,index The range is {0, 1, ..., X-1}. Therefore, in S406, UE1 actually sends PUCCH resources as follows: Figure 4e middle Partial. The base station detects PUCCH in this part.

[0163] The above describes in detail the transmission method of the uplink control channel according to an embodiment of the present invention. The transmission method of the uplink control channel according to another embodiment of the present invention will now be described. It is understood that the interaction between the network device and the terminal device described from the network device side is the same as or corresponds to the description from the terminal device side; to avoid repetition, relevant descriptions are appropriately omitted.

[0164] Figure 5 This is a schematic diagram illustrating the implementation flow of the uplink control channel transmission method according to an embodiment of the present invention, which can be applied to the network device side. For example... Figure 5 As shown, the method 500 includes:

[0165] S502: The network device sends the target configuration information.

[0166] The target configuration information includes: N physical resource blocks (PRBs) that at least one UE in the target cell can use to transmit the Physical Uplink Control Channel (PUCCH) and L candidate PUCCH resources that at least one UE in the target cell can use to transmit the PUCCH. The target cell is the cell where the target UE is located.

[0167] S504: Based on the first indication value, determine a first PUCCH resource from the L candidate PUCCH resources, the first PUCCH resource including N target PRBs, and perform PUCCH reception at the location of one or more candidate PRBs among the N target PRBs.

[0168] Therefore, after receiving the target configuration information, the UE can determine the actual number M of PRBs to be sent for PUCCH, so that the UE can meet the coverage requirements with a smaller number of PRBs.

[0169] Figure 6 This is a schematic diagram illustrating the implementation flow of the uplink control channel transmission method according to an embodiment of the present invention, which can be applied to the network device side. For example... Figure 6 As shown, the method 600 includes:

[0170] S602: The network device sends the target configuration information.

[0171] The target configuration information includes: N physical resource blocks (PRBs) that at least one UE in the target cell can use to transmit the Physical Uplink Control Channel (PUCCH) and L candidate PUCCH resources that at least one UE in the target cell can use to transmit the PUCCH. The target cell is the cell where the target UE is located.

[0172] S604: Determine a first PUCCH resource from the L candidate PUCCH resources according to the first indication value, and perform PUCCH blind detection at the positions of Yi candidate PRBs among the N target PRBs.

[0173] The first PUCCH resource includes N target PRBs, and the number of PRBs at the positions of one or more candidate PRBs among the N target PRBs is Y1, Y2,..., YK, where 1 <= Y1 < Yi <... < YK. The Yi satisfies one of the following: pre-defined by the protocol; configured by the base station; reported by the target UE. For example, when N = 8, the base station performs PUCCH blind detection at the candidate PRB positions with the number of PRBs {2, 6, 8} pre-defined by the protocol, or configured by the base station, or reported by the target UE.

[0174] Thus, after receiving the target configuration information, the UE can determine the actual number of PRBs M for sending PUCCH, enabling the UE to meet the coverage requirement with a smaller number of PRBs. Then, the UE sends PUCCH at the positions pre-defined by the protocol, configured by the base station, or reported by the target UE, and the base station performs blind detection at these positions.

[0175] Figure 7 It is a schematic diagram of the implementation process of the uplink control channel transmission method according to an embodiment of the present invention, which can be applied to the network device side. As Figure 7 shown, the method 700 includes:

[0185] The number of bits of uplink control information (UCI) carried in the PUCCH transmitted by the target UE;

[0186] The bit rate of the PUCCH sent by the target UE.

[0187] In one implementation, M satisfies at least one of the following:

[0188] If the target UE has the capability to transmit multiple PRB PUCCHs, then M is equal to N;

[0189] If the target UE does not have the ability to send multiple PRB PUCCHs, then M equals 1;

[0190] If the target UE has the capability to send a PUCCH of up to Z PRBs and Z is greater than or equal to N, then M is equal to N;

[0191] If the target UE has the PUCCH capability to send up to Z PRBs and Z is less than N, then M is equal to Z;

[0192] If the target UE has the capability to send a PUCCH containing Zi PRBs, then M is equal to Zi, where Zi is at least one of Z1, Z2…ZK, and Zi<=N. <Zi+1,1<=Z1<Z2<…<ZK,ZK> N;

The pattern is predefined by the protocol or configured by the base station. The definition of the first PRB is the index of the first PRB in the M PRBs, and the definition of the second PRB is the index of the second PRB in the M PRBs.
