[0041] The PUCCH transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0042] FIG2 is a flow chart of a PUCCH transmission method according to an embodiment of the present application. As shown in FIG2 , the method includes the following steps:

[0043] Step 200: The terminal receives the PUCCH resource configuration sent by the network side device.

[0044] Step 201: The terminal performs PUCCH transmission on one or more frequency domain units based on PUCCH resource configuration.

[0045] In the implementation of this application, a cell is composed of at least one frequency domain unit. A frequency domain unit is a group of continuous frequency domain resources, which can be a band, carrier, subband, BWP, etc. Different frequency domain units can be the same or different in size, and different frequency domain units can be discontinuous. For example, a cell is composed of four frequency domain units, and the sizes of these four frequency domain units are 3MHz, 10MHz, 5MHz, and 5MHz respectively.

[0046] For a cell consisting of at least one frequency domain unit, various embodiments of the present application provide solutions for PUCCH configuration and / or transmission. The network-side device configures PUCCH resources for the terminal, and the terminal can perform PUCCH transmission on one or more frequency domain units based on the PUCCH resource configuration sent by the network-side device.

[0047] Optionally, the time unit may be a symbol, a symbol set, a time slot, a sub-time slot, a sub-frame, a frame, or other time period, which is not specifically limited.

[0048] For example, the terminal may transmit a PUCCH in a time unit and a frequency domain unit based on the PUCCH resource configuration sent by the network-side device.

[0049] For example, the terminal may transmit multiple PUCCHs on multiple frequency domain units in one time unit based on the PUCCH resource configuration sent by the network-side device, wherein the multiple PUCCHs may overlap or not overlap in time.

[0050] For example, the terminal may transmit a PUCCH on multiple frequency domain units in one time unit based on the PUCCH resource configuration sent by the network side device. For example, different PRBs of a PUCCH resource belong to different frequency domain units.

[0051] In an embodiment of the present application, the network side configures PUCCH resources for the terminal, and the terminal can perform PUCCH transmission on one or more frequency domain units based on the PUCCH resource configuration sent by the network side device. Therefore, when a cell contains multiple frequency domain units, the spectrum resources of the cell can be used more flexibly and efficiently to improve the effectiveness and performance of the communication system.

[0052] Optionally, the PUCCH resource configuration includes at least one of the following:

[0053] A first PUCCH resource configuration, where the first PUCCH resource configuration is used to configure a first PUCCH resource, and each first PUCCH resource is configured in a frequency domain unit;

[0054] The second PUCCH resource configuration is used to configure a second PUCCH resource, and each second PUCCH resource is configured in one or more frequency domain units.

[0055] For example, the frequency domain resources of the second PUCCH resources may span different frequency domain units, and the frequency domain resources may be discontinuous, thereby avoiding insufficient resources in one frequency domain unit or obtaining a greater frequency diversity gain.

[0056] Optionally, the second PUCCH resource is used to transmit a PUCCH in a non-sequence-based PUCCH format. For example, for a sequence-based PUCCH format, it may be a PUCCH format that transmits different information by transmitting different sequences; for example, PUCCH format 0 and format 1 in NR; for a non-sequence-based PUCCH format, it may be a PUCCH format in which the UCI carried by the PUCCH is encoded, such as RM encoding or polar encoding, and then transmitted, such as PUCCH format 2, format 3 or format 4 in NR. Only PUCCH formats that are not sequence-based can have resources within multiple frequency domain units (across frequency domain units). Since the sequence-based PUCCH format needs to utilize the orthogonality between different sequences to correctly receive information, this method can avoid different parts of the sequence experiencing different channel fading and affecting the reception performance of the sequence.

[0057] Optionally, the terminal performs PUCCH transmission on one or more frequency domain units based on PUCCH resource configuration, including:

[0058] The terminal transmits one PUCCH in one time unit on one frequency domain unit based on the first PUCCH resource configuration; or

[0059] The terminal transmits multiple PUCCHs on multiple frequency domain units in one time unit based on the first PUCCH resource configuration; or

[0060] The terminal transmits one PUCCH on multiple frequency domain units in one time unit based on the second PUCCH resource configuration; or

[0061] Based on the second PUCCH resource configuration, the terminal transmits multiple PUCCHs on multiple frequency domain units in one time unit.

[0062] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is associated with a frequency domain unit.

[0063] For example, the PUCCH resource configuration (the first PUCCH resource configuration and / or the second PUCCH resource configuration) is associated with a specific frequency domain unit.

[0064] For example, the first PUCCH resource configuration and / or the second PUCCH resource configuration can be configured under the frequency domain unit configuration. The PUCCH resource configuration configured under the configuration of frequency domain unit 1 is associated with frequency domain unit 1, and the PUCCH resource configuration configured under the configuration of frequency domain unit 2 is associated with frequency domain unit 2. It can be understood that the first PUCCH resource configuration and / or the second PUCCH resource configuration is associated with the frequency domain unit, indicating that the first PUCCH resource configuration and / or the second PUCCH resource configuration belongs to its associated frequency domain unit, and the corresponding PUCCH can only be transmitted on its associated frequency domain unit. Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is a PUCCH resource configuration common to the frequency domain unit.

[0065] For example, the PUCCH resource configuration (the first PUCCH resource configuration and / or the second PUCCH resource configuration) is common to all frequency domain units (or a predefined / configured frequency domain unit set / frequency domain unit subset / frequency domain unit group), that is, when the PUCCH resource is configured, it is not associated with any frequency domain unit. It can be understood that the first PUCCH resource configuration and / or the second PUCCH resource configuration is not associated with a specific frequency domain unit, and the frequency domain unit on which the PUCCH is transmitted can be determined based on other configurations or indication information of the base station. "Not associated with any frequency domain unit" can be understood as not being one-to-one exclusively associated with any frequency domain unit, and all frequency domain units (or a predefined / configured frequency domain unit set / frequency domain unit subset / frequency domain unit group) jointly apply the common PUCCH resource configuration.

[0066] For example, the first PUCCH resource configuration and / or the second PUCCH resource configuration may be configured under the cell configuration.

[0067] Optionally, the frequency domain resources of the first PUCCH resource and / or the second PUCCH resource are determined based on the frequency domain position of the common reference point.

[0068] For example, the frequency domain resource configuration of the PUCCH resource (such as the starting physical resource block (PRB), PRB offset, etc.) is configured relative to a common reference point (such as point A). The terminal determines the frequency domain resources of the first PUCCH resource and / or the second PUCCH resource based on the frequency domain position of the common reference point.

[0069] Optionally, the method further includes:

[0070] If the frequency domain resources of the first PUCCH resource are not completely within one frequency domain unit, the terminal determines that the first PUCCH resource is unavailable, or the terminal determines that the frequency domain resources of the first PUCCH resource within one frequency domain unit are available.

[0071] Optionally, in the present application, a certain PUCCH resource being available means that the terminal can transmit PUCCH on the resource, and a resource being unavailable means that the terminal cannot transmit PUCCH on the resource.

[0072] Optionally, when the terminal determines that the PUCCH resource is available, the terminal uses the available PUCCH resource (such as a PRB within a frequency domain unit) to transmit the PUCCH.

[0073] Optionally, when the terminal determines that the PUCCH resource is unavailable, the terminal may not transmit the PUCCH or multiplex the PUCCH or the content carried by the PUCCH onto other resources for transmission.

[0074] For example, the terminal expects that the frequency domain resources of each PUCCH resource are configured within a frequency domain unit, or if the frequency domain resources of a PUCCH resource are not limited to a frequency domain unit, the PUCCH resource is not available, or if the frequency domain resources of a PUCCH resource are not limited to a frequency domain unit, the frequency domain resources of the PUCCH resource are only available in the PRBs within the frequency domain unit, and the remaining PRBs are not available.

[0075] Optionally, the terminal may determine the frequency domain unit where the PUCCH is transmitted based on the frequency domain unit corresponding to the PUCCH resource, or the terminal expects that the frequency domain unit where it is instructed or configured to transmit the PUCCH is consistent with the frequency domain unit where the PUCCH resource is configured.

[0076] Optionally, the frequency domain resources of the first PUCCH resource and / or the second PUCCH resource are determined based on the frequency domain position of the frequency domain unit.

[0077] For example, the frequency domain resource configuration of each PUCCH resource (such as the starting PRB, PRB offset, etc.) is configured relative to the starting or ending PRB position of the frequency domain unit where the transmission is located (i.e., the starting or ending position of the frequency domain unit). The terminal determines the frequency domain resources of the first PUCCH resource and / or the second PUCCH resource based on the starting or ending position of the frequency domain unit. It can be understood that the PUCCH resource configuration in this manner is a floating PUCCH resource configuration, which can be effective in any frequency domain unit (or any of the predefined / configured frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups).

[0078] Optionally, the method further includes:

[0079] If the frequency domain range of the first PUCCH resource determined based on the frequency domain position of the first frequency domain unit exceeds the frequency domain range of the first frequency domain unit, the terminal determines that the first PUCCH resource is unavailable, or the terminal adjusts the frequency domain offset of the first PUCCH resource, or the terminal determines that the frequency domain resources of the first PUCCH resource within the first frequency domain unit are available.

[0080] For example, if some PUCCH resources in the public PUCCH resource configuration cannot be accommodated in a certain frequency domain unit based on the configured bandwidth (or starting PRB and PRB offset), this PUCCH resource is invalid (or unavailable, and invalid resources and unavailable resources are understood the same way in this application) in this frequency domain unit. At this time, the terminal does not expect to be instructed to use invalid PUCCH resources (for example, the base station ensures that the above situation will not occur when configuring or scheduling PUCCH transmission), or when configured / instructed to use invalid PUCCH resources, the terminal does not transmit the PUCCH. Or if some PUCCH resources in the public PUCCH resource configuration cannot be accommodated in a certain frequency domain unit based on the configured bandwidth, the terminal adjusts the frequency domain position according to predefined rules, such as performing PRB offset, or the PUCCH resource is truncated by the bandwidth of the frequency domain unit, that is, only the PRBs falling within the frequency domain unit are available).

[0081] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration includes a first configuration part common to the frequency domain units and a second configuration part specific to the frequency domain units.

[0082] In this application, it is understood that PUCCH resource configuration refers to configuring parameters related to PUCCH channel resources, which may include at least one of the following: PUCCH resources, PUCCH resource sets, time domain location of PUCCH resources, frequency domain location of PUCCH resources, sequence, code rate, power, beam, and other related parameters. For example, PUCCH-config in the prior art is an IE used to configure PUCCH resources.

[0083] In some embodiments, the PUCCH resource configuration can be divided into two parts, one part of which is common to all frequency domain units (or predefined / configured frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups) (i.e., the same for all frequency domain units), such as resource identifier (ID), PUCCH format information configuration, time domain position, etc., and the other part is specific to each frequency domain unit (i.e., each frequency domain unit can be configured independently, and can be the same or different), such as frequency domain position (such as starting PRB position, number of PRBs, etc.), code rate, transmission power control, beam-related information, spatial information, etc.

[0084] Optionally, the method further includes:

[0085] The terminal determines the frequency domain unit where the PUCCH is transmitted based on at least one of the following:

[0086] The frequency domain units configured with the first PUCCH resource configuration and / or the second PUCCH resource configuration in the activated frequency domain units;

[0087] A frequency domain unit in which the first PUCCH resource configuration and / or the second PUCCH resource configuration is activated in the activated frequency domain units;

[0088] Frequency domain unit configured by the network side for transmitting PUCCH;

[0089] Frequency domain unit for transmitting PUCCH indicated by the network side;

[0090] PUCCH resource identifier indicated by the network side;

[0091] Frequency domain units configured by higher layer signaling or indicated by dynamic signaling;

[0092] The main frequency domain unit configured or predefined on the network side;

[0093] A frequency domain unit determined by association mapping between a physical downlink control channel PDCCH resource and a PUCCH resource;

[0094] The frequency domain unit indicated by at least one of the scheduling downlink control information DCI, configuration signaling, and activation DCI corresponding to PUCCH transmission;

[0095] Frequency domain unit determined by predefined rules.

[0096] In some embodiments, the terminal is configured with a first PUCCH resource configuration, and the terminal performs PUCCH transmission on only one frequency domain unit in one time unit. The frequency domain unit where the PUCCH transmission is located can be determined in multiple ways.

[0097] For example, PUCCH resources are configured in frequency domain units. Once a PUCCH resource is configured, it can only be transmitted on its associated frequency domain unit. During PUCCH resource configuration and frequency domain unit activation / deactivation, the base station can only have PUCCH resource configurations on at most one active frequency domain unit at a time, or only have PUCCH resource configurations activated on at most one active frequency domain unit at a time.

[0098] For example, when the base station activates one or more frequency domain units, at most only one frequency domain unit among the multiple frequency domain units is configured with PUCCH resources. For example, the base station configures multiple frequency domain unit groups, each frequency domain unit group contains one or more frequency domain units, and at most only one frequency domain unit in each frequency domain unit group has PUCCH resources configured. The base station activates or deactivates according to the frequency domain unit group.

[0099] For example, the base station can perform PUCCH resource configuration on multiple frequency domain units (for example, each frequency domain unit). When the base station activates a frequency domain unit, it indicates whether to activate the PUCCH resource configuration on the frequency domain unit. If the PUCCH resource configuration on the frequency domain unit is not activated, it means that the base station only activates the frequency domain unit, and the PUCCH resource configuration on the frequency domain unit is not available. The terminal does not transmit PUCCH on the frequency domain unit, or the base station cannot schedule the terminal to transmit PUCCH on the frequency domain unit.

[0100] For example, the base station can configure PUCCH resources on multiple frequency domain units. The base station configures or predefines a frequency domain unit as the primary frequency domain unit. For example, the frequency domain unit with the lowest index in the activated frequency domain units is the primary frequency domain unit. Only the PUCCH resource configuration on the primary frequency domain unit is available, and the PUCCH resource configuration on the remaining frequency domain units is unavailable (or in an inactive state). The terminal transmits PUCCH on the primary frequency domain unit. Optionally, the primary frequency domain unit can change during the activation / deactivation of the uplink frequency domain unit.

[0101] For example, the base station can configure PUCCH resources on multiple frequency domain units. In each time unit, the base station configures or instructs the terminal on which frequency domain unit to transmit PUCCH. For example, the base station configures a PUCCH resource switching pattern through high-level signaling to instruct the terminal on which frequency domain unit to perform PUCCH transmission in each time unit (optionally, including the use of the PUCCH resource configuration corresponding to the frequency domain unit). Or the base station indicates through dynamic signaling on which frequency domain unit to perform PUCCH transmission in a certain time unit / time period (optionally, including the use of the PUCCH resource configuration corresponding to the frequency domain unit).

[0102] For example, the base station performs PUCCH resource configuration, which is common to all frequency domain units (or predefined / configured frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups), and the base station configures or indicates the frequency domain unit where the PUCCH is transmitted.

[0103] For example, the base station indicates a frequency domain unit through higher layer signaling or L1 signaling.

[0104] For example, the base station configures one or more frequency domain units through high-layer signaling (such as radio resource control (RRC) signaling). When the RRC signaling configures multiple frequency domain units, a dynamic signaling media access control control element (MAC CE) or downlink control information (DCI) (which can be a scheduled DCI or a non-scheduled DCI) is used to indicate a frequency domain unit among the multiple frequency domain units configured by the RRC.

[0105] For example, the base station configures or defines a certain frequency domain unit as a primary frequency domain unit. For example, the frequency domain unit with the lowest index among the activated frequency domain units is the primary frequency domain unit, and the PUCCH is transmitted on the primary frequency domain unit.

[0106] For example, the terminal determines through association mapping, for example, that a specific physical downlink control channel (PDCCH) resource (control resource set (CORESET), search space (SS), etc.) is associated with a specific PUCCH resource, and determines its associated PUCCH resource based on the detected DCI (corresponding CORESET, SS, control channel element (CCE) index, etc.).

[0107] For example, for dynamically scheduled PUCCH transmissions, such as Hybrid Automatic Repeat reQuest ACKnowledgment (HARQ-ACK) PUCCH scheduled with DCI, the frequency domain unit is indicated by the scheduling DCI. Alternatively, if there is no corresponding indication field in the DCI scheduling HARQ-ACK PUCCH, a frequency domain unit determined by other means such as high-level configuration or pre-definition can be used.

[0108] For example, for semi-statically configured PUCCH transmissions, such as transmission of channel state information (CSI), scheduling request (SR), or semi-persistent scheduling (SPS) HARQ-ACK PUCCH, the frequency domain unit in which it is located can be configured by the base station through high-level signaling. For example, for CSI and SR, the base station configures the corresponding PUCCH resources and / or the frequency domain unit in which the PUCCH transmission is located when configuring each CSI and SR, or through activation of DCI indication (for PUCCH with activated DCI, such as SPS HARQ-ACK PUCCH).

[0109] In some embodiments, the terminal is configured with a first PUCCH resource configuration, and the terminal may perform PUCCH transmission on more than one frequency domain unit in one time unit. The frequency domain unit where the PUCCH transmission is located may be determined in multiple ways.

[0110] For example, PUCCH resources are configured in frequency domain units. Once a PUCCH resource is configured, it can only be transmitted on the frequency domain unit to which it is associated. When the base station is performing PUCCH resource configuration and frequency domain unit activation / deactivation, there may be more than one active frequency domain unit with available PUCCH resource configurations at the same time.

[0111] For example, the base station configures PUCCH resources on one or more (eg, each frequency domain unit), and the terminal determines the frequency domain unit where the PUCCH transmission is located according to the PUCCH resource ID indicated by the base station.

[0112] Optionally, the identifier of the first PUCCH resource and / or the second PUCCH resource is a number within the frequency domain unit (the PUCCH resource ID is only numbered within each frequency domain unit), or a number within the range of all frequency domain units (it can be understood that the PUCCH resources in all frequency domain units are uniformly numbered).

[0113] For example, the base station performs PUCCH resource configuration, which is common to all frequency domain units (or predefined / configured frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups), and the base station configures or indicates the frequency domain unit where the PUCCH is transmitted.

[0114] For example, the base station indicates multiple frequency domain units through higher layer signaling or L1 signaling.

[0115] For example, the base station configures one or more frequency domain units through high-layer signaling (such as RRC signaling). When the RRC signaling configures multiple frequency domain units, more than one frequency domain unit is indicated in the multiple frequency domain units configured by RRC through MAC CE or DCI (which can be scheduled DCI or non-scheduled DCI).

[0116] For example, for dynamically scheduled PUCCH transmissions, such as HARQ-ACK PUCCH with DCI scheduling, the frequency domain unit is indicated by the scheduling DCI. Alternatively, if there is no corresponding indication field in the DCI scheduling HARQ-ACK PUCCH, a frequency domain unit determined by other means such as high-level configuration or pre-definition can be used.

[0117] For example, for semi-statically configured PUCCH transmission, such as transmission of CSI, SR, and SPS HARQ-ACK PUCCH, the frequency domain unit in which it is located can be configured by the base station through high-level signaling. For example, for CSI and SR, the base station configures the corresponding PUCCH resources and / or the frequency domain unit in which the PUCCH transmission is located when configuring each CSI and SR, or through activation of DCI indication (for PUCCH with activated DCI, such as SPS HARQ-ACK PUCCH).

[0118] In some embodiments, the terminal is configured with a second PUCCH resource configuration, and the terminal may perform PUCCH transmission on more than one frequency domain unit in one time unit. The frequency domain unit where the PUCCH transmission is located may be determined in multiple ways.

[0119] For example, the base station high-level explicitly configures the frequency domain unit where the PUCCH transmission is located, such as configuring one or more frequency domain units where a PUCCH resource is located, or implicitly configures the frequency domain unit where the PUCCH transmission is located (for example, the terminal determines the frequency domain unit where it is located based on the starting PRB and PRB number configured for the PUCCH resource).

[0120] For example, the base station indicates more than one frequency domain unit through higher layer signaling or L1 signaling.

[0121] For example, the base station indicates more than one frequency domain unit through high-layer signaling or L1-signaling, and the terminal determines the frequency domain unit where the PUCCH is transmitted based on the base station indication and the predefined rules. For example, a PUCCH resource has some resources in the frequency domain unit A (such as the frequency domain unit in which the terminal is instructed to transmit the PUCCH) that exceed the frequency domain range of the frequency domain unit A according to its configured starting PRB and number of PRBs, then the remaining PRBs are mapped to another / other frequency domain unit (such as the UL activated frequency domain unit, the frequency domain unit that is closest to the frequency domain unit A or the frequency domain unit that is closest to the frequency domain unit A and has uplink available resources within the time unit. The other / other frequency domain unit can be determined by a predefined rule or configured by the base station).

[0122] Optionally, the scheduling DCI or activation DCI is also used to activate the indicated frequency domain unit.

[0123] For example, for the frequency domain unit where the above-mentioned DCI indicates the PUCCH transmission, in one way, the frequency domain unit indicated by the base station must be an activated frequency domain unit, and in another way, the DCI can indicate that the frequency domain unit currently in an activated or inactivated state transmits PUCCH. If the frequency domain unit indicated by the DCI is currently in an inactivated state, then receiving the DCI indicates that the frequency domain unit is activated, where the time when the frequency domain unit is activated can be determined by the base station indication or predefined rules, for example, starting from a certain time (such as the PUCCH transmission start symbol / the starting position of the time domain unit where the PUCCH is located / the predefined time interval after the end of the DCI, etc.) and is activated until other signaling or rules cause the frequency domain unit to be deactivated, or it is activated only during the PUCCH transmission scheduled by the DCI / the time unit / the time unit segment.

[0124] Optionally, the method further includes:

[0125] When the second frequency domain unit where the first PUCCH transmission is located is in an inactive state or resources are unavailable, the terminal performs at least one of the following:

[0126] Determine a third frequency domain unit in the activated frequency domain units based on a predefined rule, and perform a first PUCCH transmission in the third frequency domain unit;

[0127] Performing a first PUCCH transmission in a second frequency domain unit, the second frequency domain unit being in an inactive state after the first PUCCH transmission is transmitted;

[0128] canceling the first PUCCH transmission;

[0129] Postponing the first PUCCH transmission to the most recent available time unit in which the second frequency domain unit is in an activated state;

[0130] At least part of the uplink control information UCI carried by the first PUCCH is multiplexed and transmitted on other uplink channels.

[0131] In some embodiments, if within a certain time unit, the frequency domain unit where a certain PUCCH (first PUCCH) is transmitted is in an inactive state or resources are unavailable (for example, the transmission direction configured or indicated within the time unit is downlink, or the terminal also configures / schedules downlink transmission in the frequency domain unit in the time unit), the terminal can transmit PUCCH in any of the following ways.

[0132] For example, the terminal switches to another activated frequency domain unit to transmit the PUCCH according to predefined rules, such as the activated frequency domain unit with the smallest index / the index closest to the frequency domain unit where the PUCCH is located / the frequency domain position closest to the frequency domain unit where the PUCCH is located.

[0133] For example, the terminal still transmits the PUCCH in the frequency domain unit where the PUCCH is located. After the PUCCH is transmitted, the frequency domain unit is still in an inactive state.

[0134] For example, if other PUCCHs are configured / scheduled to be transmitted on other activated frequency domain units in the time unit (for example, indicated by DCI), the terminal switches to the other activated frequency domain units.

[0135] For example, the terminal cancels the PUCCH transmission or postpones the PUCCH transmission in the frequency domain unit to the next available time unit.

[0136] For example, the terminal multiplexes at least part of uplink control information (UCI) carried by the PUCCH on other uplink channels for transmission.

[0137] Optionally, the method further includes:

[0138] When configured or instructed to transmit different PUCCHs in different frequency domain units in the same time unit, the terminal performs at least one of the following:

[0139] Transmitting at least one of the different PUCCHs in the dynamically indicated frequency domain unit;

[0140] Transmit at least one of the different PUCCHs in the frequency domain unit indicated by the last DCI;

[0141] Transmit at least one of the different PUCCHs in the frequency domain unit where the PUCCH with the highest priority is located;

[0142] The UCI carried by different PUCCHs is multiplexed on one PUCCH for transmission.

[0143] In some embodiments, for a certain time unit, the terminal expects to be configured / instructed to transmit PUCCH on the same frequency domain unit (for example, PUCCH transmission configured for different higher layers, and PUCCH transmission indicated by multiple DCIs), or if the terminal is configured or instructed to transmit different PUCCHs in different frequency domain units for the same time unit, the terminal can transmit PUCCH in any of the following ways.

[0144] For example, if the above-mentioned different frequency domain units include a frequency domain unit dynamically indicated by the base station, the terminal transmits at least one of the above-mentioned different PUCCHs on the dynamically indicated frequency domain unit (for example, if different PUCCH time domain resources overlap, the terminal can multiplex different PUCCHs or discard part of the PUCCH transmission).

[0145] For example, if the above-mentioned different frequency domain units are indicated by multiple DCIs, the terminal can determine the frequency domain unit according to the indication of the last DCI to transmit at least one of the above-mentioned different PUCCHs. For example, if the DCI indications corresponding to multiple PDSCHs feed back their corresponding HARQ-ACK information in the same time unit, where the frequency domain units indicated by the multiple DCIs may be the same or different, the terminal determines the frequency domain unit where the HARQ-ACK feedback is located according to the indication of the last DCI corresponding to the multiple PDSCHs.

[0146] For example, the terminal transmits at least one of the above-mentioned different PUCCHs in the frequency domain unit where the PUCCH with the highest priority is located according to the priority of each PUCCH / priority of the transmission content / content type, etc. (for example, if different PUCCH time domain resources overlap, the terminal can multiplex different PUCCHs or discard some PUCCH transmissions).

[0147] FIG3 is a second flow chart of a PUCCH transmission method according to an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0148] Step 300: The network-side device determines a PUCCH resource configuration, where the PUCCH resource configuration is used by the terminal to perform PUCCH transmission on one or more frequency domain units.

[0149] Step 301: The network side device sends PUCCH resource configuration to the terminal.

[0150] In the implementation of this application, a cell is composed of at least one frequency domain unit. A frequency domain unit is a group of continuous frequency domain resources, which can be a band, carrier, subband, BWP, etc. Different frequency domain units can be the same or different in size, and different frequency domain units can be discontinuous. For example, a cell is composed of four frequency domain units, and the sizes of these four frequency domain units are 3MHz, 10MHz, 5MHz, and 5MHz respectively.

[0151] For a cell consisting of at least one frequency domain unit, various embodiments of the present application provide solutions for PUCCH configuration and / or transmission. The network-side device configures PUCCH resources for the terminal, and the terminal can perform PUCCH transmission on one or more frequency domain units based on the PUCCH resource configuration sent by the network-side device.

[0152] In an embodiment of the present application, the network side configures PUCCH resources for the terminal, and the terminal can perform PUCCH transmission on one or more frequency domain units based on the PUCCH resource configuration sent by the network side device. Therefore, when a cell contains multiple frequency domain units, the spectrum resources of the cell can be used more flexibly and efficiently to improve the effectiveness and performance of the communication system.

[0153] Optionally, the PUCCH resource configuration includes at least one of the following:

[0154] A first PUCCH resource configuration, where the first PUCCH resource configuration is used to configure a first PUCCH resource, and each first PUCCH resource is configured in a frequency domain unit;

[0155] The second PUCCH resource configuration is used to configure a second PUCCH resource, and each second PUCCH resource is configured in multiple frequency domain units.

[0156] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is associated with a frequency domain unit.

[0157] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is a PUCCH resource configuration common to the frequency domain unit.

[0158] Optionally, the second PUCCH resource is used to transmit a PUCCH in a non-sequence-based PUCCH format.

[0159] The methods provided in the various embodiments of this application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0160] The following examples illustrate the methods provided in the above embodiments of the present application through specific application scenarios.

[0161] Example 1:

[0162] Assume that a cell consists of four frequency domain units, and the sizes of these four frequency domain units (0-3) are 5MHz, 10MHz, 5MHz, and 20MHz respectively. In the same time unit, the terminal can have one or more activated frequency domain units. The base station can configure and / or activate PUCCH resources in the following ways.

[0163] Method 1-1: The base station configures or predefines a frequency domain unit as the primary frequency domain unit, such as frequency domain unit 3, and configures PUCCH resources in this frequency domain unit. The terminal then transmits PUCCH resources in this frequency domain unit. In this method, in order for the terminal to have available PUCCH resources in different time units, the base station should ensure that the primary frequency domain unit is always activated, or the base station should ensure that the primary frequency domain unit is activated when PUCCH transmission is required.

[0164] Method 1-2: The base station configures one or more frequency domain unit groups. Each frequency domain unit group configures PUCCH resources on one frequency domain unit. Only one frequency domain unit group is active in the same time unit. The terminal transmits PUCCH on the frequency domain unit configured with PUCCH resources in the active frequency domain unit group. The base station activates / deactivates frequency domain unit groups.

[0165] Method 1-3: The base station configures PUCCH resources on one or more frequency domain units. For example, the base station configures PUCCH resources on frequency domain unit 0 and frequency domain unit 3 respectively. In the same time unit, the base station ensures that only one frequency domain unit among frequency domain unit 0 and frequency domain unit 3 is in an activated state, or when activating frequency domain unit 0 and frequency domain unit 3, the base station indicates to the terminal whether its corresponding PUCCH resources are activated. If its corresponding PUCCH resources are not activated, the terminal does not transmit PUCCH on the frequency domain unit, or the PUCCH resource configuration corresponding to the frequency domain unit is unavailable. For example, if the base station activates frequency domain unit 0 and frequency domain unit 3, but indicates that the PUCCH resources of frequency domain unit 0 are activated and the PUCCH resources of frequency domain unit 3 are not activated, the terminal transmits PUCCH on frequency domain unit 0 (using its corresponding PUCCH resource configuration).

[0166] Method 1-4: The base station configures PUCCH resources on one or more frequency domain units. When the base station configures PUCCH resources on multiple frequency domain units, one of the frequency domain units is the default frequency domain unit, for example, frequency domain unit 0. When multiple frequency domain units are activated for the terminal, at most one of the multiple frequency domain units, except for frequency domain unit 0, can have PUCCH resources configured. If there is a PUCCH resource configuration on a frequency domain unit other than frequency domain unit 0 among the activated frequency domain units, the terminal uses the PUCCH resource configuration on that frequency domain unit and transmits the PUCCH resources on that frequency domain unit. If not, the PUCCH resource configuration on frequency domain unit 0 is used and the PUCCH is transmitted on frequency domain unit 0.

[0167] In the above-mentioned methods 1-1 to 1-4, PUCCH-config (IE for configuring PUCCH resources) is configured under the frequency domain unit configuration, for example, under BWP-config (assuming the frequency domain unit is BWP, IE for configuring the frequency domain unit BWP).

[0168] Mode 1-5: The base station configures a common PUCCH resource for the frequency domain unit (which may be all frequency domain units, or a predefined / configured frequency domain unit set / frequency domain unit subset / frequency domain unit group). The terminal may transmit the PUCCH on any frequency domain unit (in all frequency domain units, or in a predefined / configured frequency domain unit set / frequency domain unit subset / frequency domain unit group) according to the configuration or instruction of the base station. For example, the frequency domain unit where the PUCCH transmission is located is determined according to at least one of the following methods:

[0169] (1) Determination by predefined rules: for example, the primary frequency domain unit, or the frequency domain unit with the smallest index / lowest frequency among all activated uplink frequency domain units (groups), or the frequency domain unit with the best channel quality, such as RSRP.

[0170] (2) Base station configuration or indication: For dynamically scheduled PUCCH transmission, such as HARQ-ACK PUCCH with DCI scheduling, the frequency domain unit in which it is located is indicated by the scheduling DCI. Or if there is no corresponding indication field in the DCI for scheduling HARQ-ACK PUCCH, the frequency domain unit determined by other means such as high-level configuration or pre-definition can be used. For semi-statically configured PUCCH transmission, such as the transmission of CSI / SR / SPS HARQ-ACK PUCCH, the frequency domain unit in which it is located can be configured by the base station through high-level signaling. For example, for CSI and SR, the base station configures the corresponding PUCCH resources and / or the frequency domain unit in which the PUCCH transmission is located when configuring each CSI and SR, or indicates it by activating DCI. For example, for CSI / SR, the base station configures the corresponding PUCCH resource ID and the frequency domain unit index in which the PUCCH transmission is located when performing CSI / SR configuration.

[0171] Optionally, for the frequency domain unit where the above-mentioned DCI indicates the PUCCH transmission, in one embodiment, the terminal expects the frequency domain unit indicated by the base station to be an activated frequency domain unit. In another embodiment, the DCI may indicate that the frequency domain unit currently in an activated or inactivated state transmits PUCCH. If the frequency domain unit indicated by the DCI is currently in an inactivated state, then receiving the DCI indicates that the frequency domain unit is activated, where the time when the frequency domain unit is activated may be determined by a base station indication or a predefined rule, for example, starting from a certain time (such as the PUCCH transmission start symbol / the starting position of the time domain unit where the PUCCH is located / a predefined time interval, etc.) and is activated until other signaling or rules cause the frequency domain unit to be deactivated, or it is activated only during the PUCCH transmission period / the time unit / the time unit segment.

[0172] Optionally, for the frequency domain unit where the PUCCH transmission is determined in the above manner, in one implementation, the terminal expects that the frequency domain units where multiple PUCCH transmissions are configured in a certain time unit are the same. In another implementation, within a certain time unit, if the frequency domain unit where the PUCCH is located determined in the above manner is in an inactive state or the resource is unavailable, the terminal transmits the PUCCH in any of the following ways:

[0173] (1) The terminal switches to another activated frequency domain unit to transmit the PUCCH according to a predefined rule, such as the activated frequency domain unit with the smallest index / the index closest to the frequency domain unit where the PUCCH is located / the frequency domain position closest to the frequency domain unit where the PUCCH is located.

[0174] (2) The terminal still transmits the PUCCH on the frequency domain unit where the PUCCH is located. After the PUCCH is transmitted, the frequency domain unit is still in an inactive state.

[0175] (3) If other PUCCHs are configured / scheduled to be transmitted on other activated frequency domain units in the time unit (for example, indicated by DCI), the terminal switches to the other activated frequency domain units.

[0176] (4) The terminal cancels the PUCCH transmission.

[0177] (5) Optionally, for a certain time unit, the terminal expects to be configured / instructed to transmit PUCCH on the same frequency domain unit. For example, if multiple DCIs schedule the terminal to transmit different HARQ-ACK information in the same time unit, the terminal expects the frequency domain units of the PUCCHs indicated by the multiple DCIs to be the same, or the terminal determines the frequency domain unit of the PUCCH according to the last DCI indication, or if the terminal is configured or instructed to transmit different PUCCHs in different frequency domain units, the terminal transmits in any of the following ways:

[0178] (1) If the above-mentioned different frequency domain units include a frequency domain unit dynamically indicated by the base station, the terminal transmits at least one of the above-mentioned different PUCCHs on the dynamically indicated frequency domain unit (for example, if different PUCCH time domain resources overlap, the terminal can multiplex different PUCCHs or discard part of the PUCCH transmission).

[0179] (2) The terminal transmits at least one of the above-mentioned different PUCCHs in the frequency domain unit where the PUCCH with the highest priority is located according to the priority of each PUCCH / the priority of the transmission content / the content type, etc. (for example, if different PUCCH time domain resources overlap, the terminal can multiplex different PUCCHs or discard some PUCCH transmissions).

[0180] In the above methods 1-5, PUCCH-config (IE used to configure PUCCH resources) is configured under the cell configuration, such as servingCell-config (IE used to configure the serving cell).

[0181] Example 2:

[0182] Assume that a cell consists of four frequency domain units, with sizes of 0-3 being 5 MHz, 10 MHz, 5 MHz, and 20 MHz, respectively. In the same time unit, a terminal can have one or more active frequency domain units. The base station can configure PUCCH resources in the following ways.

[0183] Method 2: At the same time, more than one frequency domain unit may have available PUCCH resource configurations, and PUCCH transmissions may be transmitted on more than one frequency domain unit. The base station may configure PUCCH resources using the following methods 2-1 and 2-2.

[0184] Method 2-1: The base station performs PUCCH resource configuration on multiple (for example, each frequency domain unit). In one embodiment, the PUCCH resource ID is numbered only within each frequency domain unit. When the base station instructs the terminal to transmit PUCCH, it needs to indicate the terminal PUCCH resource ID and its corresponding frequency domain unit ID / index. The terminal determines its corresponding specific PUCCH resource based on the two, for example, which frequency domain unit to use which PUCCH and what transmission parameters (such as the sequence used, code rate, power, beam information, etc., at least one transmission parameter) to use for transmission. In another embodiment, the PUCCH resource ID is numbered within all frequency domain units, and the frequency domain unit where the PUCCH resource is configured is the frequency domain unit where the PUCCH resource is transmitted. When the base station instructs the terminal to transmit PUCCH, it indicates the PUCCH resource ID, and the terminal can determine its corresponding specific PUCCH resource and the frequency domain unit according to the PUCCH resource ID. In one embodiment, if the base station has configured PUCCH resources only in one frequency domain unit, the terminal transmits PUCCH in that frequency domain unit according to its corresponding PUCCH configuration. If the base station configures PUCCH resources in multiple frequency domain units, in one embodiment, when the base station activates a frequency domain unit, the PUCCH resources corresponding to the frequency domain unit are also activated (i.e., its corresponding PUCCH configuration is available). In another embodiment, when the base station activates a frequency domain unit, it indicates whether to activate its corresponding PUCCH resources. The base station may activate only a certain frequency domain unit without activating the PUCCH resource configuration on it.

[0185] Method 2-2: The base station configures PUCCH resources that are common to all frequency domain units. For example, when configuring PUCCH resources, they are not associated with any specific frequency domain unit. The base station configures or indicates the frequency domain unit in which the PUCCH is transmitted. Optionally, the method for each frequency domain unit in which the PUCCH resource is located can be the same as the above methods 1-5.

[0186] Optionally, if the terminal does not support / is not enabled to simultaneously transmit PUCCH in different frequency domain units, the terminal expects to be instructed to transmit PUCCH in the same frequency domain unit, the same as the above methods 1-5, or if the terminal is configured or instructed to transmit different PUCCHs in frequency domain units, the terminal determines that the PUCCH transmission method can be the same as the above methods 1-5.

[0187] Optionally, if the terminal supports / is enabled to simultaneously transmit PUCCH in different frequency domain units, if the terminal is configured or instructed to transmit different PUCCHs in the frequency domain units, the terminal transmits different PUCCHs in the frequency domain units respectively configured or instructed.

[0188] Optionally, the above-mentioned terminal supports the transmission of PUCCH in different frequency domain units, and the different frequency domain units meet certain requirements, for example, the different frequency domain units belong to different frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups (the frequency domain unit sets / frequency domain unit subsets / frequency domain unit groups can be pre-defined by the protocol or reported by the terminal / configured by the base station), and the intervals between the different frequency domain units meet certain requirements, etc. In one embodiment, when the base station configures or instructs the terminal to transmit different PUCCHs in different frequency domain units, it ensures that the different frequency domain units meet the certain requirements, and the terminal transmits its own PUCCH in different frequency domain units according to the configuration or instruction of the base station. In one embodiment, the base station configures or instructs the terminal to transmit different PUCCHs in different frequency domain units. If the different frequency domain units do not meet the certain requirements, the terminal transmits part of the PUCCHs in the different PUCCHs according to predefined rules, such as PUCCH corresponding priority / transmission time early or late / bearing content / scheduling type (such as semi-static configuration of dynamic scheduling priority), etc. For example, the terminal determines the PUCCH with the highest transmission priority, does not transmit / discards / cancels the PUCCH that cannot be transmitted simultaneously with the highest priority, and if there are any remaining PUCCHs, repeats the above steps in the remaining PUCCHs.

[0189] Example 3:

[0190] Assume that a cell consists of four frequency domain units, with sizes of 0-3 being 5 MHz, 10 MHz, 5 MHz, and 20 MHz, respectively. In the same time unit, a terminal can have one or more active frequency domain units. The base station can configure PUCCH resources in the following ways.

[0191] Mode 3: A PUCCH resource may be in one or more frequency domain units (PRBs of a PUCCH may be in different frequency domain units), where the frequency domain unit associated with / corresponding to a PUCCH may be:

[0192] (1) Base station high-level display configuration.

[0193] Optionally, the PRBs of the PUCCH in each frequency domain unit may be configured separately, or the starting PRB and / or number of PRBs of the PUCCH in each frequency domain unit may be the same, such as PUCCH2 in FIG4 .

[0194] (2) Implicit determination (e.g., the terminal determines the frequency domain unit in which the PUCCH resource is located based on the starting PRB and the number of PRBs configured therein) or determination based on predefined rules. For example, if a PUCCH resource has some resources in frequency domain unit A (e.g., the frequency domain unit in which the terminal is instructed to transmit the PUCCH) that exceed the frequency domain range of frequency domain unit A based on the starting PRB and the number of PRBs configured therein, the remaining PRBs are mapped to another / other frequency domain unit (e.g., the UL activated frequency domain unit that is closest to frequency domain unit A. The other / other frequency domain unit can be determined by a predefined method or configured by the base station), such as PUCCH1 in FIG4 .

[0195] Optionally, only resources of a non-sequence-based PUCCH format can be within multiple frequency domain units.

[0196] In this embodiment 3, the frequency domain resources of a PUCCH resource may span different frequency domain units, and the frequency domain resources may be discontinuous, thereby avoiding insufficient resources in a frequency domain unit or obtaining a greater frequency diversity gain.

[0197] The PUCCH transmission method provided in the embodiment of the present application may be performed by a PUCCH transmission device. In the embodiment of the present application, the PUCCH transmission device performing the PUCCH transmission method is taken as an example to illustrate the PUCCH transmission device provided in the embodiment of the present application.
