As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0039] Next, with reference to the accompanying drawings, the PUCCH transmission method provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0040] Figure 2 It is one of the flow diagrams of the PUCCH transmission method provided by the embodiments of this application. As Figure 2 shown, the method includes the following steps:

[0041] Step 200: The terminal receives the PUCCH resource configuration sent by the network-side device.

[0042] Step 201: The terminal performs PUCCH transmission on one or more frequency-domain units based on the PUCCH resource configuration.

[0043] In the implementation of this application, a cell consists of at least one frequency-domain unit. A frequency-domain unit is a group of continuous frequency-domain resources, which can be band, carrier, subband, BWP, etc. The sizes of different frequency-domain units can be the same or different, and different frequency-domain units may not be continuous. For example, a cell consists of four frequency-domain units, and the sizes of these four frequency-domain units are 3 MHz, 10 MHz, 5 MHz, and 5 MHz respectively.

[0044] For a cell composed of at least one frequency-domain unit, the 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.

[0045] Optionally, the time unit may be a time period such as a symbol, a set of symbols, a time slot, a sub-time slot, a sub-frame, a frame, etc., and is not specifically limited.

[0046] For example, the terminal can transmit one PUCCH on one frequency-domain unit in one time unit based on the PUCCH resource configuration sent by the network-side device.

[0047] For example, the terminal can transmit multiple PUCCHs on multiple frequency-domain units in one time unit based on the PUCCH resource configuration sent by the network-side device. Among them, the multiple PUCCHs may or may not overlap in time.

[0048] For example, the terminal can transmit one 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 one PUCCH resource belong to different frequency-domain units.

[0049] In the embodiments of the present application, by configuring PUCCH resources for the terminal by the network side, 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, so that when a cell includes multiple frequency-domain units, the spectrum resources of the cell can be utilized more flexibly and efficiently to improve the effectiveness and performance of the communication system.

[0050] Optionally, the PUCCH resource configuration includes at least one of the following:

[0051] The first PUCCH resource configuration is used to configure the first PUCCH resource, and each first PUCCH resource is configured within one frequency-domain unit;

[0052] The second PUCCH resource configuration is used to configure the second PUCCH resource, and each second PUCCH resource is configured within one or more frequency-domain units.

[0053] For example, the frequency-domain resources of the second PUCCH resource can span different frequency-domain units, and its frequency-domain resources may not be continuous, which can avoid insufficient resources within one frequency-domain unit or obtain a greater frequency diversity gain.

[0054] Optionally, the second PUCCH resource is used to transmit a PUCCH in a sequence-independent PUCCH format. For example, for a sequence-based PUCCH format, it can be a PUCCH format that transmits different information by transmitting different sequences; for example, PUCCH format 0 and format 1 in NR. For a sequence-independent PUCCH format, it can be a PUCCH format in which the UCI carried by the PUCCH is transmitted after being encoded, such as RM coding or polar coding. For example, PUCCH format 2, format 3, or format 4 in NR. Only the resources of the sequence-independent PUCCH format can be 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 fades and affecting the reception performance of the sequence.

[0055] Optionally, the terminal performs PUCCH transmission on one or more frequency domain units based on the PUCCH resource configuration, including:

[0056] The terminal performs the transmission of one PUCCH on one frequency domain unit in one time unit based on the first PUCCH resource configuration; or,

[0057] The terminal performs the transmission of multiple PUCCHs on multiple frequency domain units in one time unit based on the first PUCCH resource configuration; or,

[0058] The terminal performs the transmission of one PUCCH on multiple frequency domain units in one time unit based on the second PUCCH resource configuration; or,

[0059] The terminal performs the transmission of multiple PUCCHs on multiple frequency domain units in one time unit based on the second PUCCH resource configuration.

[0060] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration are associated with the frequency domain unit.

[0061] 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.

[0062] For example, the first PUCCH resource configuration and / or the second PUCCH resource configuration may be configured under a 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 being associated with a frequency domain unit means that the first PUCCH resource configuration and / or the second PUCCH resource configuration belong to the associated frequency domain unit, and the corresponding PUCCH can only be transmitted on the associated frequency domain unit. Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration are PUCCH resource configurations common to frequency domain units.

[0063] 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 set / subset / group of frequency domain units), that is, when configuring the PUCCH resource, 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 are not associated with a specific frequency domain unit, and on which frequency domain unit the PUCCH is transmitted can be determined according to other configurations or indication information of the base station. "Not associated with any frequency domain unit" can be understood as not having a one-to-one exclusive association with any frequency domain unit, and all frequency domain units (or a predefined / configured set / subset / group of frequency domain units) jointly apply the common PUCCH resource configuration.

[0064] For example, the first PUCCH resource configuration and / or the second PUCCH resource configuration may be configured under a cell configuration.

[0065] 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 a common reference point.

[0066] For example, the frequency domain resource configuration of the PUCCH resource (such as the configuration of the starting physical resource block (PRB), PRB offset, etc.) is configured relative to a certain 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.

[0067] Optionally, the method further includes:

[0068] 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.

[0069] Optionally, the availability of a certain PUCCH resource in this application means that the terminal can transmit PUCCH on this resource, and the unavailability of the resource means that the terminal cannot transmit PUCCH on this resource.

[0070] Optionally, when the terminal determines that the PUCCH resource is available, the terminal uses the available PUCCH resource (such as the PRBs within a frequency domain unit) to transmit PUCCH.

[0071] Optionally, when the terminal determines that the PUCCH resource is unavailable, the terminal may not transmit this PUCCH or multiplex the content carried by this PUCCH or PUCCH onto other resources for transmission.

[0072] 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 restricted within a frequency domain unit, then this PUCCH resource is unavailable, or if the frequency domain resources of a PUCCH resource are not restricted within a frequency domain unit, then only the PRBs within the frequency domain unit of the frequency domain resources of this PUCCH resource are available, and the remaining PRBs are unavailable.

[0073] Optionally, the terminal may determine the frequency domain unit where the PUCCH transmission is located according to the frequency domain unit corresponding to the PUCCH resource, or the terminal expects that the frequency domain unit where it is indicated or configured to transmit PUCCH is the same as the frequency domain unit where the PUCCH resource is configured.

[0074] 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.

[0075] For example, the frequency domain resource configuration of each PUCCH resource (such as the configuration of the starting PRB, PRB offset, etc.) is configured relative to the starting or ending PRB position of the frequency domain unit where it is transmitted (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 method is a floating PUCCH resource configuration and can take effect within any (or any one of the predefined / configured sets of frequency domain units / subsets of frequency domain units / groups of frequency domain units) frequency domain unit.

[0076] Optionally, the method further includes:

[0077] 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 resource of the first PUCCH resource within the first frequency-domain unit is available.

[0078] For example, when some PUCCH resources in the common PUCCH resource configuration cannot be accommodated in a certain frequency-domain unit based on the configured bandwidth (or the starting PRB and PRB offset), this PUCCH resource is invalid (or unavailable in this application, and the resource being invalid and unavailable can be understood in the same way) in this frequency-domain unit. At this time, the terminal does not expect to be instructed to use an invalid PUCCH resource (for example, the base station ensures that the above situation will not occur when configuring or scheduling PUCCH transmission), or when being configured / instructed to use an invalid PUCCH resource, the terminal does not transmit this PUCCH. Or when some PUCCH resources in the common 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 a predefined rule, such as performing a 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).

[0079] 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.

[0080] In this application, it can be understood that the PUCCH resource configuration refers to the parameters related to configuring the PUCCH channel resources, and may include at least one of the following: PUCCH resources, PUCCH resource sets, the time-domain position of the PUCCH resources, the frequency-domain position of the PUCCH resources, sequences, code rates, power, beam, and other related parameters. For example, PUCCH-config in the prior art is an IE used to configure PUCCH resources.

[0081] In some embodiments, the PUCCH resource configuration can be divided into two parts. One part is common to all frequency-domain units (or a predefined / configured set of frequency-domain units / frequency-domain unit subset / frequency-domain unit group) (i.e., the same for all frequency-domain units), such as resource identifier (ID), PUCCH format information configuration, time-domain position, etc. The other part is specific to each frequency-domain unit (i.e., each frequency-domain unit can be independently configured, 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.

[0082] Optionally, the method further includes:

[0083] The terminal determines the frequency-domain unit where the PUCCH transmission is located based on at least one of the following:

[0084] A frequency-domain unit in the activated frequency-domain units that is configured with the first PUCCH resource configuration and / or the second PUCCH resource configuration;

[0085] A frequency-domain unit in the activated frequency-domain units that has the first PUCCH resource configuration and / or the second PUCCH resource configuration activated;

[0086] The frequency-domain unit configured by the network side for transmitting the PUCCH;

[0087] The frequency-domain unit indicated by the network side for transmitting the PUCCH;

[0088] The PUCCH resource identifier indicated by the network side;

[0089] The frequency-domain unit configured by higher-layer signaling or indicated by dynamic signaling;

[0090] The primary frequency-domain unit configured by the network side or predefined;

[0091] The frequency-domain unit determined by the association mapping between the physical downlink control channel PDCCH resource and the PUCCH resource;

[0092] The frequency-domain unit indicated by at least one of the scheduling downlink control information DCI, configuration signaling, and activation DCI corresponding to the PUCCH transmission;

[0093] The frequency-domain unit determined by a predefined rule.

[0094] In some embodiments, the terminal is configured with the first PUCCH resource configuration. The terminal performs PUCCH transmission on only one frequency-domain unit in one time unit, and there are multiple ways to determine the frequency-domain unit where the PUCCH transmission is located.

[0095] For example, when the PUCCH resource is configured in a frequency-domain unit, once a PUCCH resource is configured, it can only be transmitted on its associated frequency-domain unit. When the base station configures the PUCCH resource and activates / deactivates the frequency-domain unit, at most one activated frequency-domain unit has the PUCCH resource configuration at the same time, or at most one activated frequency-domain unit has the activated PUCCH resource configuration at the same time.

[0096] For example, when the base station activates one or more frequency domain units, at most one of the multiple frequency domain units is configured with PUCCH resources. For example, the base station configures multiple groups of frequency domain units, each group of frequency domain units contains one or more frequency domain units, and at most one of the frequency domain units in each group of frequency domain units is configured with PUCCH resources. The base station activates or deactivates according to the groups of frequency domain units.

[0097] For example, the base station can configure PUCCH resources on multiple frequency domain units (such as each frequency domain unit). When the base station activates a frequency domain unit, it indicates whether to activate the PUCCH resource configuration on that frequency domain unit. If the PUCCH resource configuration on that frequency domain unit is not activated, it means that the base station only activates that frequency domain unit, and the PUCCH resource configuration on that frequency domain unit is unavailable. The terminal does not transmit PUCCH on that frequency domain unit, or the base station cannot schedule the terminal to transmit PUCCH on that frequency domain unit.

[0098] 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 among 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 configurations on the remaining frequency domain units are unavailable (or in an inactive state). The terminal transmits PUCCH on the primary frequency domain unit. Optionally, in the activation / deactivation of the uplink frequency domain unit, the primary frequency domain unit can change accordingly.

[0099] For example, the base station can configure PUCCH resources on multiple frequency domain units. In each time unit, the base station configures or indicates on which frequency domain unit the terminal transmits PUCCH. For example, the base station configures a PUCCH resource switching pattern through high-layer signaling to indicate on which frequency domain unit the terminal performs PUCCH transmission in each time unit (optionally, including using the PUCCH resource configuration corresponding to that 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 / certain time period (optionally, including using the PUCCH resource configuration corresponding to that frequency domain unit).

[0100] For example, the base station configures PUCCH resources, and this PUCCH resource configuration is common to all frequency domain units (or a predefined / configured set of frequency domain units / frequency domain unit subset / frequency domain unit group). The base station configures or indicates the frequency domain unit where PUCCH transmission is located.

[0101] For example, the base station indicates a frequency domain unit through high-layer signaling or L1-signaling.

[0102] 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 frequency domain unit is indicated among the multiple frequency domain units configured by the RRC through dynamic signaling Media Access Control Control Element (MAC CE) or Downlink Control Information (DCI) (which can be scheduling DCI or non-scheduling DCI).

[0103] For example, the base station configures or defines a certain 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, and the PUCCH is transmitted on the primary frequency domain unit.

[0104] For example, the terminal determines through associated mapping. For example, a specific Physical Downlink Control Channel (PDCCH) resource (Control Resource Set (CORESET), Search Space (SS), etc.) is associated with a specific PUCCH resource, and the associated PUCCH resource is determined according to the detected DCI (the corresponding CORESET, SS, Control Channel Elements (CCE) index, etc.).

[0105] For example, for dynamically scheduled PUCCH transmissions, such as for Hybrid Automatic Repeat reQuest ACKnowledgment (HARQ-ACK) PUCCH scheduled by DCI, the frequency domain unit where it is located is indicated by the scheduling DCI. Or if there is no corresponding indication field in the DCI scheduling the HARQ-ACK PUCCH, the frequency domain unit determined by other methods such as high-layer configuration or predefined can be adopted.

[0106] For example, for semi-statically configured PUCCH transmissions, such as transmitting channel state information (CSI), scheduling requests (SRs), or semi-persistent scheduling (SPS) HARQ-ACK PUCCHs, the frequency domain units where they are located can be configured by the base station through higher layer signaling. For example, for CSI and SR, when the base station configures each CSI and SR, it configures the corresponding PUCCH resources and / or the frequency domain units where the PUCCH transmissions are located, or it is indicated by activating DCI (for PUCCHs with activating DCI, such as SPS HARQ-ACK PUCCHs).

[0107] In some embodiments, the terminal is configured with a first PUCCH resource configuration, and the terminal can perform PUCCH transmissions on more than one frequency domain unit in a time unit. There can be multiple ways to determine the frequency domain units where the PUCCH transmissions are located.

[0108] For example, when the 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. When the base station configures PUCCH resources and activates / deactivates frequency domain units, there are available PUCCH resource configurations on more than one active frequency domain unit at the same time.

[0109] For example, the base station configures PUCCH resources on one or more (such as each frequency domain unit), and the terminal determines the frequency domain units where the PUCCH transmissions are located according to the PUCCH resource IDs indicated by the base station.

[0110] Optionally, the identifier of the first PUCCH resource and / or the second PUCCH resource is a number within the frequency domain unit (the numbering of the PUCCH resource ID is only numbered within each frequency domain unit), or it is a number within the range of all frequency domain units (it can be understood that the PUCCH resources within all frequency domain units are uniformly numbered).

[0111] For example, the base station configures PUCCH resources, and this PUCCH resource configuration is common to all frequency domain units (or a predefined / configured set / subset / group of frequency domain units), and the base station configures or indicates the frequency domain units where the PUCCH transmissions are located.

[0112] For example, the base station indicates multiple frequency domain units through higher layer signaling or L1-signaling.

[0113] For example, the base station configures one or more frequency domain units through high-layer signaling (such as RRC signaling). When multiple frequency domain units are configured by RRC signaling, more than one frequency domain unit is indicated among the multiple frequency domain units configured by RRC through MAC CE or DCI (which can be scheduling DCI or non-scheduling DCI).

[0114] For example, for dynamically scheduled PUCCH transmissions, such as HARQ-ACK PUCCH scheduled by DCI, the frequency domain unit where it is located is indicated by the scheduling DCI. Or if there is no corresponding indication field in the DCI scheduling HARQ-ACK PUCCH, the frequency domain unit determined by other methods such as high-layer configuration or predefined can be adopted.

[0115] For example, for semi-statically configured PUCCH transmissions, such as transmitting CSI, SR, SPS HARQ-ACK PUCCH, the frequency domain unit where it is located can be configured by the base station through high-layer signaling. For example, for CSI and SR, when the base station configures each CSI and SR, it configures the corresponding PUCCH resource and / or the frequency domain unit where the PUCCH transmission is located, or is indicated by the activation DCI (for PUCCH with activation DCI, such as SPS HARQ-ACK PUCCH).

[0116] In some embodiments, the terminal is configured with a second PUCCH resource configuration. The terminal can perform PUCCH transmission on more than one frequency domain unit in a time unit, and there are various ways to determine the frequency domain unit where the PUCCH transmission is located.

[0117] For example, the base station explicitly configures the frequency domain unit where the PUCCH transmission is located through high-layer signaling, 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 according to the starting PRB and the number of PRBs where the PUCCH resource is configured).

[0118] For example, the base station indicates more than one frequency domain unit through high-layer signaling or L1-signaling.

[0119] 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 PUCCH transmission is located according to the indication of the base station in combination with predefined rules. For example, for a PUCCH resource, according to the configured starting PRB and the number of PRBs, if part of its resources in frequency domain unit A (such as the frequency domain unit where the terminal is instructed to transmit this PUCCH) exceeds the frequency domain range of frequency domain unit A, the remaining PRBs are mapped to another / other frequency domain units (such as in the UL active frequency domain units, the frequency domain unit closest to frequency domain unit A or the frequency domain unit closest to frequency domain unit A and having uplink available resources in this time unit. The determination method of another / other frequency domain units can be determined by predefined rules or configured by the base station).

[0120] Optionally, the scheduling DCI or the activation DCI is also used to activate the indicated frequency domain unit.

[0121] For example, for the frequency domain unit where the above DCI indicates PUCCH transmission, in one way, the frequency domain unit indicated by the base station must be an active frequency domain unit. In another way, the DCI can indicate that the PUCCH is transmitted in a frequency domain unit that is currently in an active or inactive state. If the frequency domain unit indicated by the DCI is currently in an inactive state, receiving this DCI means that this frequency domain unit is activated, and the time when this frequency domain unit is activated can be indicated by the base station or determined by predefined rules. For example, it is activated from a certain time (such as the starting symbol of PUCCH transmission / the starting position of the time domain unit where PUCCH is located / a predefined time interval after the end of DCI, etc.) until other signaling or rules deactivate this frequency domain unit, or it is only activated during the PUCCH transmission scheduled by the DCI / during the time unit / segment of the time unit where the PUCCH is located.

[0122] Optionally, the method further includes:

[0123] In the case where the second frequency domain unit where the first PUCCH transmission is located is in an inactive state or the resources are unavailable, the terminal performs at least one of the following:

[0124] Determine a third frequency domain unit in the active frequency domain unit based on predefined rules and perform the first PUCCH transmission in the third frequency domain unit;

[0125] Perform the first PUCCH transmission in the second frequency domain unit, and the second frequency domain unit becomes inactive after the first PUCCH transmission is transmitted;

[0126] Cancel the first PUCCH transmission;

[0127] Postpone the first PUCCH transmission to the available time unit when the nearest second frequency domain unit is in an active state;

[0128] Multiplex at least part of the uplink control information (UCI) carried on the first PUCCH and transmit it on other uplink channels.

[0129] In some embodiments, if within a certain time unit, the frequency domain unit where a certain PUCCH (the first PUCCH) is transmitted is in an inactive state or the resource is unavailable (for example, the configured or indicated transmission direction within this time unit is downlink, or the terminal is also configured / scheduled for downlink transmission in this frequency domain unit within this time unit), the terminal can transmit the PUCCH in any of the following ways.

[0130] For example, the terminal switches to another active frequency domain unit to transmit the PUCCH according to a predefined rule, such as the active frequency domain unit with the smallest index / closest index to the frequency domain unit where this PUCCH is located / closest frequency domain position to the frequency domain unit where this PUCCH is located.

[0131] For example, the terminal still transmits the PUCCH in the frequency domain unit where this PUCCH is located, and after the PUCCH transmission, this frequency domain unit remains in an inactive state.

[0132] For example, if in this time unit, there are other PUCCHs (such as indicated by DCI) configured / scheduled to be transmitted on other active frequency domain units, the terminal switches to this other active frequency domain unit.

[0133] For example, the terminal cancels the PUCCH transmission or defers the PUCCH transmission in this frequency domain unit to the next available time unit.

[0134] For example, the terminal multiplexes at least part of the uplink control information (Uplink Control Information, UCI) carried on this PUCCH and transmits it on other uplink channels.

[0135] Optionally, the method further includes:

[0136] In the case where the terminal is configured or indicated to transmit different PUCCHs in different frequency domain units in the same time unit, the terminal performs at least one of the following:

[0137] Transmit at least one of the different PUCCHs in the dynamically indicated frequency domain unit;

[0138] Transmit at least one of the different PUCCHs in the frequency domain unit indicated by the last DCI;

[0139] Transmit at least one of the different PUCCHs in the frequency domain unit where the PUCCH with the highest priority is located;

[0140] Multiplex the UCI carried on different PUCCHs and transmit it on one PUCCH.

[0141] In some embodiments, for a certain time unit, the terminal expects to be configured / instructed to transmit PUCCH on the same frequency domain unit (e.g., for different high-layer configured PUCCH transmissions and PUCCH transmissions indicated by multiple DCIs), or if the terminal is configured or instructed to transmit different PUCCHs on different frequency domain units in the same time unit, the terminal can transmit PUCCH in any of the following ways.

[0142] For example, if the different frequency domain units above include the frequency domain unit dynamically indicated by the base station, the terminal transmits at least one of the different PUCCHs above on the dynamically indicated frequency domain unit (e.g., if the time domain resources of different PUCCHs overlap, the terminal can perform multiplexing between different PUCCHs or discard part of the PUCCH transmissions).

[0143] For example, if the different frequency domain units above 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 different PUCCHs above. For example, if the DCIs corresponding to multiple PDSCHs indicate to feedback their corresponding HARQ-ACK information in the same time unit, and the frequency domain units indicated by multiple DCIs can 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 multiple PDSCHs.

[0144] For example, the terminal transmits at least one of the different PUCCHs above on the frequency domain unit where the PUCCH with the highest priority / transmission content priority / content type, etc. is located (e.g., if the time domain resources of different PUCCHs overlap, the terminal can perform multiplexing between different PUCCHs or discard part of the PUCCH transmissions).

[0145] Figure 3 This is the second flowchart of the PUCCH transmission method provided by the embodiments of the present application. As Figure 3 shown, the method includes the following steps:

[0146] Step 300, the network side device determines the PUCCH resource configuration, and the PUCCH resource configuration is used for the terminal to perform PUCCH transmission on one or more frequency domain units.

[0147] Step 301, the network side device sends the PUCCH resource configuration to the terminal.

[0148] In the implementation of this application, a cell consists of at least one frequency-domain unit. A frequency-domain unit is a group of continuous frequency-domain resources, which can be a band, a carrier, a subband, a BWP, etc. Different frequency-domain units can have the same or different sizes, and different frequency-domain units can be discontinuous. For example, a cell consists of four frequency-domain units with sizes of 3 MHz, 10 MHz, 5 MHz, and 5 MHz respectively.

[0149] For a cell consisting of at least one frequency-domain unit, the embodiments of this 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.

[0150] In the embodiments of this application, by configuring PUCCH resources for the terminal through the network side, 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. Thus, when a cell contains multiple frequency-domain units, the spectrum resources of the cell can be utilized more flexibly and efficiently to improve the effectiveness and performance of the communication system.

[0151] Optionally, the PUCCH resource configuration includes at least one of the following:

[0152] The first PUCCH resource configuration is used to configure the first PUCCH resource, and each first PUCCH resource is configured within one frequency-domain unit;

[0153] The second PUCCH resource configuration is used to configure the second PUCCH resource, and each second PUCCH resource is configured within multiple frequency-domain units.

[0154] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is associated with the frequency-domain unit.

[0155] Optionally, the first PUCCH resource configuration and / or the second PUCCH resource configuration is a PUCCH resource configuration common to the frequency-domain unit.

[0156] Optionally, the second PUCCH resource is used to transmit PUCCH in a PUCCH format that is not sequence-based.

[0157] The methods provided by the embodiments of this application are based on the same inventive concept. Therefore, the implementations of the methods can be referred to each other, and the repeated parts will not be elaborated.

[0158] The following uses embodiments of specific application scenarios to illustrate the methods provided by the above embodiments of this application.

[0159] Embodiment 1:

[0160] Suppose 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, a terminal can have one or more active frequency-domain units. The base station can configure and / or activate PUCCH resources in the following ways.

[0161] Method 1-1: The base station configures or predefines a certain frequency-domain unit as the primary frequency-domain unit, such as frequency-domain unit 3, and configures PUCCH resources on this frequency-domain unit. The terminal transmits PUCCH resources on this frequency-domain unit. In this method, in order to enable the terminal to have available PUCCH resources in different time units, the base station should ensure that the primary frequency-domain unit is always in an active state, or the base station should ensure that the primary frequency-domain unit is in an active state when PUCCH needs to be transmitted.

[0162] Method 1-2: The base station configures one or more groups of frequency-domain units. In each group of frequency-domain units, PUCCH resources are configured on one frequency-domain unit. In the same time unit, only one group of frequency-domain units is in an active state. The terminal performs PUCCH transmission on the frequency-domain unit in the active group of frequency-domain units where PUCCH resources are configured. The base station activates / deactivates in units of groups of frequency-domain units.

[0163] 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 of frequency-domain unit 0 and frequency-domain unit 3 is in an active state, or when activating frequency-domain unit 0 and frequency-domain unit 3, the base station indicates to the terminal whether the corresponding PUCCH resources are activated. If the corresponding PUCCH resources are not activated, the terminal does not transmit PUCCH on this frequency-domain unit, or the PUCCH resource configuration corresponding to this frequency-domain unit is unavailable. For example, 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, then the terminal transmits PUCCH on frequency-domain unit 0 (using its corresponding PUCCH resource configuration).

[0164] 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, such as frequency domain unit 0. When the terminal activates multiple frequency domain units, among the multiple frequency domain units except frequency domain unit 0, at most one frequency domain unit can be configured with PUCCH resources. If there is a frequency domain unit other than frequency domain unit 0 among the activated frequency domain units that is configured with PUCCH resources, the terminal uses the PUCCH resource configuration on this frequency domain unit and transmits PUCCH resources on this frequency domain unit. If not, it uses the PUCCH resource configuration on frequency domain unit 0 and transmits PUCCH on frequency domain unit 0.

[0165] In the above Methods 1-1 to 1-4, PUCCH-config (the IE for configuring PUCCH resources) is configured under the frequency domain unit configuration, for example, below BWP-config (assuming the frequency domain unit is BWP, the IE for configuring the frequency domain unit BWP).

[0166] Method 1-5: The base station configures PUCCH resources common to the frequency domain units (which can be all frequency domain units, or a predefined / configured set / subset / group of frequency domain units). The terminal can transmit PUCCH on any one of the (all frequency domain units, or a predefined / configured set / subset / group of frequency domain units) according to the configuration or indication of the base station. For example, determine the frequency domain unit where PUCCH is transmitted according to at least one of the following methods:

[0167] (1) Determined 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 the frequency domain unit with the best RSRP.

[0168] (2) Base station configuration or indication: For dynamically scheduled PUCCH transmissions, such as HARQ-ACK PUCCHs scheduled by DCI, the frequency domain unit where it is located is indicated by the scheduling DCI. Or if there is no corresponding indication field in the DCI scheduling the HARQ-ACK PUCCH, other methods such as higher layer configuration or predefined methods can be used to determine the frequency domain unit. For semi-statically configured PUCCH transmissions, such as transmitting CSI / SR / SPS HARQ-ACK PUCCHs, the frequency domain unit where it is located can be configured by the base station through higher layer signaling. For example, for CSI and SR, when the base station configures each CSI and SR, it configures the corresponding PUCCH resource and / or the frequency domain unit where the PUCCH transmission is located, or indicates it through an active DCI. For example, for CSI / SR, when the base station configures CSI / SR, it configures the corresponding PUCCH resource ID and configures the index of the frequency domain unit where the PUCCH transmission is located.

[0169] Optionally, for the frequency domain unit where the above DCI indicates the PUCCH transmission, in one implementation, the terminal expects the frequency domain unit indicated by the base station to be an active frequency domain unit. In another implementation, the DCI can indicate that the PUCCH is transmitted on a frequency domain unit that is currently in an active or inactive state. If the frequency domain unit indicated by the DCI is currently in an inactive state, receiving this DCI indicates that this frequency domain unit is activated. The time when this frequency domain unit is activated can be determined by the base station indication or a predefined rule. For example, it is activated from a certain time (such as the starting symbol of the PUCCH transmission / the starting position of the time domain unit where the PUCCH is located / a predefined time interval, etc.) until other signaling or rules deactivate this frequency domain unit, or it is only activated during the PUCCH transmission / during the time unit / within the time unit segment.

[0170] Optionally, for the method of determining the frequency domain unit where the PUCCH transmission is located as described above, 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 by the above method is in an inactive state or the resource is unavailable, the terminal transmits this PUCCH in any of the following ways:

[0171] (1) The terminal switches to another active frequency domain unit to transmit this PUCCH according to a predefined rule. For example, the active frequency domain unit with the smallest index / the index closest to the frequency domain unit where this PUCCH is located / the active frequency domain unit with the frequency domain position closest to the frequency domain unit where this PUCCH is located.

[0172] (2) The terminal still transmits this PUCCH on the frequency domain unit where this PUCCH is located. After the PUCCH transmission, this frequency domain unit remains in an inactive state.

[0173] (3) If there is other PUCCH configured / scheduled for transmission on other activated frequency domain units (e.g., indicated by DCI) during this time unit, the terminal switches to such other activated frequency domain units.

[0174] (4) The terminal cancels the PUCCH transmission.

[0175] (5) Optionally, for a certain time unit, the terminal expects to be configured / indicated to transmit PUCCH on the same frequency domain unit. For example, if there are multiple DCIs scheduling the terminal to transmit different HARQ-ACK information during the same time unit, the terminal expects the frequency domain units where the PUCCHs indicated by the multiple DCIs are located to be the same, or the terminal determines the frequency domain unit where the PUCCH is located according to the last DCI indication, or if it is configured or indicated to transmit different PUCCHs on different frequency domain units, the terminal transmits in any of the following ways:

[0176] (1) If the above different frequency domain units include the frequency domain unit dynamically indicated by the base station, the terminal transmits at least one of the above different PUCCHs on the dynamically indicated frequency domain unit (e.g., if the time domain resources of different PUCCHs overlap, the terminal can multiplex between different PUCCHs or discard part of the PUCCH transmission).

[0177] (2) The terminal transmits at least one of the above different PUCCHs on the frequency domain unit where the PUCCH with the highest priority / transmission content priority / content type, etc. is located (e.g., if the time domain resources of different PUCCHs overlap, the terminal can multiplex between different PUCCHs or discard part of the PUCCH transmission).

[0178] In the above manners 1 - 5, PUCCH-config (IE for configuring PUCCH resources) is configured in the cell configuration, such as below servingCell-config (IE for configuring the serving cell).

[0179] Embodiment 2:

[0180] Suppose 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. During the same time unit, the terminal can have one or more activated frequency domain units. The base station can configure PUCCH resources in the following ways.

[0181] Method 2: At the same time, there can be more than one frequency domain unit with available PUCCH resource configuration, and PUCCH transmission can be performed on more than one frequency domain unit. Among them, the base station can perform PUCCH resource configuration through the following methods 2-1 and 2-2.

[0182] Method 2-1: The base station performs PUCCH resource configuration on multiple (for example, each frequency domain unit). In one implementation, the numbering of the PUCCH resource ID is only within each frequency domain unit. When the base station instructs the terminal to transmit PUCCH, it needs to indicate the PUCCH resource ID and its corresponding frequency domain unit ID / index to the terminal. The terminal determines its corresponding specific PUCCH resource based on the two, for example, which PUCCH to use in which frequency domain unit and what transmission parameters (such as at least one transmission parameter among the used sequence, coding rate, power, beam information, etc.) to use for transmission. In another implementation, the numbering of the PUCCH resource ID is within all frequency domain units, and the frequency domain unit where the PUCCH resource configuration is located is the frequency domain unit where the PUCCH resource is transmitted. When the base station instructs the terminal to transmit PUCCH and indicates the PUCCH resource ID, the terminal can determine its corresponding specific PUCCH resource and the frequency domain unit where it is located. In one implementation, if the base station configures PUCCH resources only in one frequency domain unit, the terminal transmits PUCCH in this frequency domain unit according to its corresponding PUCCH configuration. If the base station configures PUCCH resources in multiple frequency domain units, in one implementation, when the base station activates a frequency domain unit, the corresponding PUCCH resources of this frequency domain unit are also activated (that is, its corresponding PUCCH configuration is available). In another implementation, when the base station activates a frequency domain unit, it indicates whether to activate its corresponding PUCCH resources. The base station can activate only a certain frequency domain unit without activating the PUCCH resource configuration on it.

[0183] Method 2-2: The base station configures PUCCH resources common to all frequency domain units. For example, when configuring PUCCH resources, it is not associated with any specific frequency domain unit, and the base station configures or indicates the frequency domain unit where the PUCCH transmission is located. Among them, optionally, the method for each frequency domain unit where the PUCCH resource is located can be the same as the above method 1-5.

[0184] Optionally, if the terminal does not support / is not enabled to transmit PUCCH simultaneously in different frequency domain units, the same as the above method 1-5, the terminal expects to be instructed to transmit PUCCH in the same frequency domain unit. Or if the terminal is configured or instructed to transmit different PUCCHs in the frequency domain unit, the method for the terminal to determine the PUCCH transmission can be the same as the above method 1-5.

[0185] Optionally, if the terminal supports / is enabled to transmit PUCCH on different frequency domain units simultaneously, then if the terminal is configured or instructed to transmit different PUCCH on the frequency domain units, the terminal transmits different PUCCH on the respective configured or instructed frequency domain units.

[0186] Optionally, the above terminal supports transmitting PUCCH on 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 predefined by the protocol or reported by the terminal / configured by the base station), and the interval between the different frequency domain units meets certain requirements, etc. In one implementation, when the base station configures or instructs the terminal to transmit different PUCCH on different frequency domain units, ensuring that the different frequency domain units meet the certain requirements, then the terminal transmits its respective PUCCH on different frequency domain units according to the base station configuration or instruction. In one implementation, when the base station configures or instructs the terminal to transmit different PUCCH on different frequency domain units, if the different frequency domain units do not meet the certain requirements, then the terminal transmits some of the different PUCCH according to predefined rules, such as the PUCCH corresponding priority / transmission time sequence / borne content / scheduling type (such as the priority of dynamic scheduling is semi-statically configured), etc. For example, the terminal determines to transmit the PUCCH with the highest priority, does not transmit / discard / cancel the PUCCH that cannot be transmitted simultaneously with the highest priority, and if there are still remaining PUCCH, then among the remaining PUCCH, repeat the above steps.

[0187] Example 3:

[0188] Suppose 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 active frequency domain units. The base station can configure PUCCH resources in the following ways.

[0189] Method 3: One PUCCH resource can be within one or more frequency domain units (the PRBs of one PUCCH are in different frequency domain units), and the frequency domain units associated / corresponding to one PUCCH can be:

[0190] (1) Explicit configuration by the base station higher layer.

[0191] Optionally, the PRBs of this PUCCH in each frequency domain unit can be configured separately, or the starting PRB and / or the number of PRBs of the PUCCH in each frequency domain unit are the same, such as Figure 4 PUCCH2 in

[0192] (2) Implicit determination (e.g., the terminal determines the frequency domain unit it is in based on the starting PRB and the number of PRBs configured for the PUCCH resource) or determination according to a predefined rule. For example, for a PUCCH resource, according to the starting PRB and the number of PRBs it is configured with, if some of its resources exceed the frequency domain range of frequency domain unit A (e.g., the frequency domain unit where the terminal is instructed to transmit this PUCCH), the remaining PRBs are mapped to another / other frequency domain units (e.g., in the UL active frequency domain unit, the other / other frequency domain unit closest to frequency domain unit A can be determined by a predefined method or configured by the base station). For example, Figure 4 PUCCH1 in

[0193] Optionally, only PUCCH formats that are not sequence-based can have resources in multiple frequency domain units.

[0194] In this Embodiment 3, the frequency domain resources of a PUCCH resource can span different frequency domain units, and its frequency domain resources can be discontinuous, which can avoid insufficient resources in one frequency domain unit or obtain a greater frequency diversity gain.
