The embodiment of the invention provides a transmission method. Referring to fig. 3, fig. 3 is a block diagram of a network system to which the embodiment of the present invention is applicable, as shown in fig. 3, including a terminal Device 11 and a network side Device 12, where the terminal Device 11 may be a terminal Device side Device such as a mobile phone, a tablet (Tablet PersonalComputer), a Laptop (Laptop Computer), a personal digital assistant (PersonalDigital Assistant, abbreviated as PDA), a mobile internet Device (Mobile Internet Device, MID) or a web Device (web Device), and it should be noted that the embodiment of the present invention is not limited to a specific type of the terminal Device 11. The network-side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, etc., or the network side device 12 may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) together with a plurality of transmission reception points (Transmission Reception Point, TRP) which it manages and controls. It should be noted that, in the embodiment of the present invention, the specific type of the network side device 12 is not limited.

In this embodiment, for at least two downlink transmissions, for example, a Multi-transmission receiving point (Multiple Transmission and Reception Point, multi-TRP) transmission, the network side device 12 may configure at least two physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources for the at least two downlink transmissions to transmit uplink control information (Uplink Control Information, UCI).

The UCI may include at least one of hybrid automatic repeat request (Hybrid Automatic Repeat request, HARQ) ACK information, HARQ NACK information, channel state information (Channel State Information, CSI), and uplink scheduling request (Scheduling Request, SR), etc.

The PUCCH resources are transmission resources of PUCCH, for example, time domain resources, frequency domain resources, and the like. Optionally, the at least two PUCCH resources are configured at a Cell (i.e. Cell) and/or Bandwidth Part (BWP) level.

Note that the PUCCH resource may be configured based on a control resource set (Control Resource Set, core) or a Search Space (i.e., search Space). Specifically, a CORESET or search space identification corresponding to each downlink transmission (e.g., downlink TRP transmission) is associated with the PUCCH resource of that downlink transmission.

The terminal device 11 may transmit the target UCI through the target PUCCH resource. The target UCI includes all or part of information in UCI corresponding to the at least two first PUCCH resources.

The target PUCCH resource may be determined according to an association relationship between at least two first PUCCH resources. Wherein, the first PUCCH resource is a transmission resource of the first PUCCH resource. The at least two first PUCCH resources, that is, the at least two PUCCH resources configured by the network side device 12 for the at least two downlink transmissions.

Optionally, in this embodiment, all or part of information in UCI corresponding to at least two first PUCCH resources may be transmitted through the target PUCCH resource under a condition that UCI corresponding to at least two PUCCH resources needs to be fed back simultaneously.

The association relationship may include, but is not limited to, an overlapping relationship of the at least two first PUCCH resources in a time domain and/or in a frequency domain. For example, in case that the at least two first PUCCH resources are orthogonal in a time domain, the target PUCCH resource may include at least two first PUCCH resources transmitted within the same transmission time unit; in the case that the association relationship is orthogonal in the frequency domain and the PUCCH format does not include any one of the preset formats, the target PUCCH resource includes the at least two first PUCCH resources that completely overlap or partially overlap the time domain transmission resources; in case that the at least two first PUCCH resources are not orthogonal in the time domain, are not orthogonal in the frequency domain, or are orthogonal in the frequency domain and the PUCCH format does not include any of the preset formats, the target PUCCH resource includes a second PUCCH resource of the at least two first PUCCH resources, or a predefined third PUCCH resource.

The transmission time unit may include any one of a symbol, a sub-slot, a sub-frame, a radio frame, a symbol set, a sub-slot set, a sub-frame set, and a radio frame set. The preset formats may include format 1, format 3, and format 4.

The capability information of the terminal device may include capability information of whether the terminal device supports simultaneous transmission of at least two uplink channels. For example, in the case that the terminal device supports simultaneous transmission of at least two uplink channels, the target PUCCH resource may be the at least two first PUCCH resources that are simultaneously transmitted; in the case that the terminal device does not support simultaneous transmission of at least two PUCCH resources, the target PUCCH resource may be a PUCCH resource determined based on the association relationship. Wherein, the simultaneous transmission may refer to transmission of the resources in the same time domain.

In the embodiment of the invention, the terminal equipment transmits the UCI through the target PUCCH resources, wherein the target PUCCH resources are PUCCH resources determined according to the association relation of at least two PUCCH resources corresponding to downlink transmission, so that the UCI transmission corresponding to a plurality of PUCCH resources can be realized under different conditions, and the UCI transmission reliability corresponding to a plurality of PUCCH resources can be improved.

The embodiment of the invention provides a transmission method. Referring to fig. 4, fig. 4 is a flowchart of a transmission method provided in an embodiment of the present invention, as shown in fig. 4, including the following steps:

step 401, transmitting target uplink control information UCI through a target physical uplink control channel PUCCH resource;

In this embodiment, the UCI may include at least one of HARQ ACK information, HARQ NACK information, CSI, SR, and the like. The target UCI may include all or part of information in UCI corresponding to at least two first PUCCH resources. For example, in the case where the at least two downlink transmissions include the first downlink transmission and the second downlink transmission, the target UCI may include UCI corresponding to PUCCH resources corresponding to the first downlink transmission and UCI corresponding to PUCCH resources corresponding to the second downlink transmission, or may be one UCI corresponding to PUCCH resources corresponding to the first downlink transmission and UCI corresponding to PUCCH resources corresponding to the second downlink transmission, or may include part of information in UCI corresponding to PUCCH resources corresponding to the first downlink transmission and part of information in UCI corresponding to PUCCH resources corresponding to the second downlink transmission, which is not limited in this embodiment.

Note that, the target UCI may also be information that does not correspond to the at least two downlink transmissions, which is not limited in this embodiment.

Alternatively, the at least two downlink transmissions may be at least two downlink TRP transmissions. The at least two first PUCCH resources may be at least two PUCCH resources configured by the network side device for the at least two downlink transmissions, that is, PUCCH resources corresponding to the at least two downlink transmissions. The first PUCCH resource is a transmission resource of the first PUCCH, for example, a time domain resource, a frequency domain resource, or the like. Specifically, the at least two first PUCCH resources may be configured for a cell and/or a bandwidth part in a hierarchical manner.

The association relationship of the at least two first PUCCH resources may include, but is not limited to, an overlapping relationship of the at least two first PUCCH resources in a time domain and/or in a frequency domain.

The target PUCCH resource may be a PUCCH resource determined according to an association relationship of at least two first PUCCH resources. It should be noted that, the target PUCCH resource may include one or more PUCCH resources.

Optionally, in this embodiment, all or part of information in UCI corresponding to at least two first PUCCH resources may be transmitted through the target PUCCH resource under a condition that UCI corresponding to at least two first PUCCH resources needs to be fed back simultaneously.

According to the embodiment, the target UCI is transmitted through the target PUCCH, wherein the target PUCCH is the PUCCH determined according to the association relation of at least two PUCCH resources corresponding to downlink transmission, and the UCI uplink transmission mode is standardized. In addition, the target PUCCH resource is determined based on the association relation of the PUCCH resources corresponding to at least two downlink transmissions, so that the reliability of UCI transmission can be improved.

Optionally, in the case that the association relationship is orthogonal in the time domain, the target PUCCH resource includes the at least two first PUCCH resources transmitted in the same transmission time unit.

In this embodiment, in a case where the at least two first PUCCH resources are orthogonal in the time domain, the target PUCCH resource may include at least two first PUCCH resources transmitted in the same transmission time unit. The transmission time unit may include any one of a symbol, a sub-slot, a sub-frame, a radio frame, a symbol set, a sub-slot set, a sub-frame set, and a radio frame set.

In practical applications, when the network side device configures at least two PUCCH resources orthogonal to the time domain resources for the at least two downlink transmissions, HARQ information, CSI, and the like corresponding to the at least two downlink transmissions may be transmitted on the at least two PUCCH resources orthogonal to the time domain resources, and the at least two PUCCH resources may be transmitted in the same transmission time unit. Wherein, the HARQ information includes at least one of HARQ ACK information and HARQ NACK information.

For example, as shown in fig. 5, for Multi-TRP transmission, if a PUCCH1 resource and a PUCCH2 resource orthogonal to a time domain resource are configured on the network side, HARQ information and CSI corresponding to two downlink transmissions are transmitted on the PUCCH1 resource and the PUCCH2 resource, where the PUCCH1 resource and the PUCCH2 resource are transmitted in the same slot.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource.

In this embodiment, when the at least two first PUCCH resources are orthogonal in the time domain, UCI corresponding to the at least two first PUCCH resources may be transmitted using the at least two first PUCCH resources transmitted in the same transmission time unit, and simultaneous feedback of UCI corresponding to the at least two first PUCCH resources may be ensured.

Optionally, in the case that the association relationship is orthogonal in the frequency domain and the PUCCH format does not include any one of the preset formats, the target PUCCH resource includes the at least two first PUCCH resources that completely overlap or partially overlap the time domain transmission resources.

In this embodiment, the preset formats may include format 1, format 3, and format 4. Specifically, in the case where the at least two first PUCCH resources are orthogonal in the frequency domain and the PUCCH format does not include any one of format 1, format 3 and format 4, the target PUCCH resource may include the at least two first PUCCH resources in which time domain transmission resources are completely overlapped or partially overlapped.

In practical applications, when the network side device configures at least two PUCCH resources with orthogonal frequency domain resources, and the PUCCH formats of the at least two PUCCH resources with orthogonal frequency domain resources do not include any format of format 1, equation 3 and equation 4, HARQ information and CSI corresponding to the at least two downlink transmissions are transmitted on the at least two PUCCH resources with completely overlapped or partially overlapped time domain transmission resources.

For example, as shown in fig. 6, for Multi-TRP transmission, if two frequency domain resources, namely, a PUCCH1 resource and a PUCCH2 resource, are configured on the network side, wherein the PUCCH1 resource (wherein the PUCCH format of the PUCCH1 resource is format 0) is used for transmitting HARQ information and CSI corresponding to downlink TRP1 transmission, and the PUCCH2 resource (wherein the PUCCH format of the PUCCH2 resource is format 2) is used for transmitting HARQ information and CSI corresponding to downlink TRP2 transmission, the two HARQ information and CSI corresponding to downlink transmission may be transmitted on the PUCCH1 resource and PUCCH2 resource, and the time domain transmission resources of the PUCCH1 resource and PUCCH2 resource completely overlap.

In the drawings, HARQ ACK/NACK means at least one of HARQ ACK and HARQ NACK. For example, HARQ ACK/NACK1 represents at least one of HARQ ACK1 and HARQ NACK 1; HARQ ACK/NACK2 means at least one of HARQ ACK2 and HARQ NACK 2.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource.

In this embodiment, when the at least two first PUCCH resources are orthogonal in the frequency domain and the PUCCH format does not include any one of the preset formats, the UCI corresponding to the at least two first PUCCH resources may be transmitted using the at least two first PUCCH resources that are completely overlapped or partially overlapped by the time domain transmission resource, and simultaneous feedback of the UCI corresponding to the at least two first PUCCH resources may be ensured.

Optionally, in the case that the association relationship is a target association relationship, the target PUCCH resource includes a second PUCCH resource of the at least two first PUCCH resources, or a predefined third PUCCH resource;

the target association relationship is that the at least two first PUCCH resources are not orthogonal in a time domain, are not orthogonal in a frequency domain, or are orthogonal in the frequency domain and the PUCCH format does not include any format of a preset format.

In this embodiment, the at least two first PUCCH resources being non-orthogonal in the time domain may mean that the at least two first PUCCH resources at least include a partial overlap of time domain resources. The at least two first PUCCH resources being non-orthogonal in the frequency domain may mean that the at least two first PUCCH resources include at least a partial overlap of frequency domain resources. The preset formats may include format 1, format 3, and format 4.

In practical applications, when the network side device configures at least two PUCCH resources with non-orthogonal time domain resources, or at least two PUCCH resources with non-orthogonal frequency domain resources, or at least two PUCCH resources with orthogonal frequency domain resources and in any one of format 1, format 3 and format 4, one PUCCH resource may be selected from the at least two PUCCH resources to transmit HARQ ACK information or HARQ NACK information corresponding to the at least two downlink transmissions and part of information in CSI, or a predefined PUCCH resource may be used to transmit HARQ ACK information corresponding to the at least two downlink transmissions or HARQ NACK information and all or part of information in CSI.

For example, as shown in fig. 7, for Multi-TRP transmission, if two PUCCH resources orthogonal to frequency domain resources, namely, PUCCH1 resource and PUCCH2 resource are configured on the network side, PUCCH1 resource (wherein PUCCH format of PUCCH1 resource is format 3) is used for transmitting HARQ information and CSI corresponding to downlink TRP1 transmission, PUCCH2 resource (wherein PUCCH format of PUCCH2 resource is format 4) is used for transmitting HARQ information and CSI corresponding to downlink TRP2 transmission, PUCCH1 resource and PUCCH2 resource may not be transmitted simultaneously, and PUCCH2 resource may be discarded at this time, and only PUCCH1 resource may be transmitted.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource.

Optionally, the second PUCCH resource is a PUCCH resource with the highest priority among the at least two first PUCCH resources;

or alternatively

The second PUCCH resource is a PUCCH resource carrying at least one of HARQ ACK information and HARQ NACK information in UCI corresponding to the at least two first PUCCH resources.

In an embodiment, at least one of the at least two first PUCCH resources may be discarded according to a priority relation of the PUCCH resources. Specifically, partial information in UCI corresponding to at least two first PUCCH resources may be transmitted using a PUCCH resource with the highest priority among the at least two first PUCCH resources.

Optionally, the priority relation of the PUCCH resource may be related to at least one of:

information carried by UCI corresponding to the PUCCH resource, and a downlink channel corresponding to the PUCCH resource.

In this embodiment, the information carried by UCI corresponding to the PUCCH resource may include HARQ information and/or CSI, where the HARQ information may include at least one of HARQ ACK information and HARQ NACK information. For example, the priority of PUCCH resources of the corresponding UCI carrying HARQ ACK information or HARQ NACK information is higher than the priority of PUCCH resources of the corresponding UCI carrying channel state information CSI.

The downlink channel corresponding to the PUCCH resource may refer to a downlink channel transmitted by downlink transmission corresponding to information carried by the PUCCH resource. For example, the priority of PUCCH resources corresponding to the presence of a physical downlink control channel (Physical Downlink Shared Channel, PDCCH) transmission is higher than the priority of PUCCH resources corresponding to the absence of a PDCCH transmission. The PUCCH resource corresponding to the PDCCH-present transmission may refer to a PUCCH resource corresponding to the PDCCH-present downlink transmission, and the PUCCH resource corresponding to the PDCCH-absent transmission may refer to a PUCCH resource corresponding to the PDCCH-absent downlink transmission.

Optionally, the priority relation of the PUCCH resource includes:

the priority of the PUCCH resource of the corresponding UCI carrying HARQ information is higher than the priority of the PUCCH resource of the corresponding UCI carrying channel state information CSI.

For example, as shown in fig. 8, the network side device configures two PUCCH resources, that is, a PUCCH1 resource and a PUCCH2 resource, where the time domain resource or the frequency domain resource is not orthogonal, the PUCCH1 resource is used for transmitting HARQ information corresponding to downlink TRP1 transmission, the PUCCH2 resource is used for transmitting CSI corresponding to downlink TRP2 transmission, and according to the above-mentioned priority relationship of the PUCCH, the PUCCH2 resource may be discarded, and the PUCCH1 resource is transmitted.

Optionally, the priority relation of the PUCCH resource may further include:

the priority of the PUCCH resource corresponding to the presence of a physical downlink control channel PDCCH transmission is higher than the priority of the PUCCH resource corresponding to the absence of a PDCCH transmission.

For example, the network side device configures two PUCCH resources, namely, a PUCCH1 resource and a PUCCH2 resource, where the downlink TRP1 transmission corresponding to the PUCCH1 resource has PDCCH transmission, the downlink TRP2 transmission corresponding to the PUCCH2 resource does not have PDCCH transmission, and the PUCCH2 resource may be discarded and the PUCCH1 resource is transmitted.

It should be noted that, in the case that the PUCCH resource with the highest priority among the at least two first PUCCH resources includes a plurality of PUCCH resources, the terminal device may select a PUCCH resource from the plurality of PUCCH resources with the highest priority to transmit part of information in UCI corresponding to the at least two first PUCCH resources.

In another embodiment, only PUCCH resources bearing HARQ information among the at least two first PUCCH resources may be transmitted, where the HARQ information includes at least one of HARQ ACK information and HARQ NACK information.

For example, as shown in fig. 9, if two PUCCH resources, that is, a PUCCH1 resource and a PUCCH2 resource, which are not orthogonal to each other in time domain resources or frequency domain resources are configured on the network side, where the PUCCH1 resource is used for transmitting HARQ information and CSI corresponding to downlink TRP1 transmission, and the PUCCH2 resource is used for transmitting HARQ information and CSI corresponding to downlink TRP2 transmission, the HARQ information corresponding to downlink TRP1 transmission and the HARQ information corresponding to downlink TRP2 transmission may be preferentially transmitted on the PUCCH1 resource.

When the number of PUCCH resources carrying HARQ ACK information or HARQ NACK information in at least two first PUCCH resources is plural, one PUCCH resource may be selected from the plurality of PUCCH resources carrying HARQ information to transmit HARQ information carried in the plurality of PUCCH resources.

Note that, when the size of the information that can be maximally carried by any PUCCH resource of the plurality of PUCCH resources carrying HARQ information is smaller than the size of the HARQ information carried by the plurality of PUCCH resources, only the HARQ information carried by a portion of the PUCCH resources may be transmitted, and the HARQ information carried by a portion of the PUCCH resources may be discarded.

Optionally, the priority transmission PUCCH resource may be determined according to the priority relationship of the PUCCH resource, and the HARQ information carried by the PUCCH resource is transmitted, for example, the HARQ information carried by the PUCCH resource corresponding to the downlink transmission in which the PDCCH exists is preferentially transmitted; or the terminal equipment selects the PUCCH resource of the priority transmission and transmits the HARQ information carried by the PUCCH resource.

When the number of PUCCH resources to be preferentially transmitted is plural, which is determined according to the priority relation of PUCCH resources, one PUCCH resource may be selected from the plural PUCCH resources based on the terminal device, and HARQ information carried by the PUCCH resource may be transmitted.

Optionally, the third PUCCH resource is: and selecting a PUCCH resource from a PUCCH resource set configured by at least one of the high-level signaling and the DCI.

In this embodiment, the predefined third PUCCH resource may be a PUCCH resource selected from a PUCCH resource set configured by at least one of higher layer signaling and downlink control information (Downlink control information, DCI). The PUCCH resource set configured by at least one of the higher layer signaling and DCI may include one or at least two PUCCH resources.

In practical applications, the PUCCH resource set may be configured through higher layer signaling (e.g., radio resource control (Radio Resource Control, RRC) signaling), and the terminal device may further select PUCCH resources from the UCCH resource set to perform target UCI transmission. Or the first PUCCH resource set is configured through the high-level signaling, and the second PUCCH resource set is indicated to the terminal equipment through DCI, so that the terminal equipment can select PUCCH resources from the second PUCCH resources to carry out target UCI transmission. The PUCCH resources in the second PUCCH resource set belong to the first PUCCH resource set, that is, the second PUCCH resource set is composed of at least part of the PUCCH resources in the first PUCCH resource set.

Note that, in the case of indicating the PUCCH resource set by DCI, each PUCCH resource indication field value may correspond to at least one PUCCH resource in the PUCCH resource set, and each PUCCH resource indication field may correspond to at least one PUCCH resource indication field value.

Optionally, in the case that the PUCCH resource set is configured by higher layer signaling, each downlink transmission or control resource set or search space corresponds to at least one PUCCH resource in the PUCCH resource set.

In this embodiment, in the case that the PUCCH resource set is configured by higher layer signaling, each downlink transmission (for example, downlink TRP transmission) corresponds to at least one PUCCH resource in the PUCCH resource set or the control resource set or the search space.

Optionally, in the case that the PUCCH resource set is indicated by DCI, each PUCCH resource indication field value corresponds to at least two PUCCH resources in the PUCCH resource set, and/or each PUCCH resource indication field corresponds to at least two PUCCH resource indication field values.

In an embodiment, in the case that the PUCCH resource set is indicated by DCI, each PUCCH resource indication (i.e. PUCCH Resource Indicator) field value may correspond to at least two PUCCH resources, and in this case, each PUCCH resource indication field may correspond to one or at least two PUCCH resource indication field values.

In another embodiment, in case the PUCCH resource set is indicated by DCI, each PUCCH resource indication field may correspond to at least two PUCCH resource indication field values, i.e. each physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission may correspond to at least two PUCCH resource indication field values. At this time, each PUCCH resource indication field value may correspond to one or at least two PUCCH resources.

In another embodiment, in case that the PUCCH resource set is indicated by DCI, each PUCCH resource indication field may correspond to at least two PUCCH resource indication field values, and each PUCCH resource indication field value may correspond to at least two PUCCH resources.

For example, as shown in fig. 10, PUCCH resources are indicated by DCI, wherein for downlink TRP1 transmission, PUCCH1 resources are indicated by 00, and PUCCH2 resources are indicated by 01; for downlink TRP2 transmission, PUCCH1 resources are indicated by 00 and PUCCH3 resources are indicated by 10. And because the PUCCH1 time domain resource has conflict, the PUCCH2 resource and the PUCCH3 resource are utilized for transmission.

It should be noted that, in this embodiment, the first PUCCH resource set may be configured through higher layer signaling, where the first PUCCH resource set may include at least one PUCCH resource. And further, a second PUCCH resource set may be indicated by DCI, where PUCCH resources in the second PUCCH resource set belong to the first PUCCH resource set.

In the case where the PUCCH resource set configured by at least one of the higher layer signaling and DCI includes at least two PUCCH resources, the terminal device may select one of the at least two optional PUCCH resources to transmit the information according to the HARQ information corresponding to the plurality of downlink transmissions and the size self-adaptation of the CSI. Wherein, the HARQ information may include at least one of HARQ ACK information and HARQ NACK information.

Optionally, PUCCH resources in the PUCCH resource set may be associated with the at least two first PUCCH resources.

Optionally, the PUCCH resource set may include the at least two first PUCCH resources, or the beam indication information corresponding to the PUCCH resource set includes beam indication information corresponding to the at least two first PUCCH resources.

For example, as shown in fig. 11, for Multi-TRP transmission, if the network side device configures two PUCCH resources that are not orthogonal to time domain resources or frequency domain resources, that is, PUCCH1 resources and PUCCH2 resources, at this time, HARQ information and CSI corresponding to the two downlink transmissions are transmitted on a predefined PUCCH3 resource, where beam indication information of the PUCCH3 resource may be configured by the network side.

Alternatively, as shown in fig. 12, the beam indication information of the PUCCH3 resource may be beam indication information corresponding to the PUCCH1 resource and the PUCCH2 resource.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource, and the PUCCH3 resource is a predefined PUCCH resource.

Optionally, in the case that the target PUCCH resource includes the at least two first PUCCH resources, the at least two first PUCCH resources indicate TPMI to transmit by using a target transmission precoding matrix, or transmit by using a code division multiplexing manner.

In this embodiment, in the case that the target PUCCH resource includes the at least two first PUCCH resources, the at least two first PUCCH resources may use a target transmission precoding matrix indicator (Transmission Precoding Matrix Indicator, TPMI). Alternatively, the target TPMI may be at least one TPMI in a TPMI set with a level of N, where N is an integer greater than 1.

For example, in the case where the number of antennas of the terminal device is 2, a codebook of tpmi=0 among the codebooks of Rank (i.e., rank) 2, that is

And transmitting the at least two first PUCCH resources.

In this embodiment, the target TPMI may be used to transmit the at least two first PUCCH resources when the time domain resources of the at least two first PUCCH resources are completely orthogonal and the frequency domain resources are completely orthogonal.

For example, as shown in fig. 13, for Multi-TRP transmission, if the network side configures PUCCH resources that are completely orthogonal to both time domain resources and frequency domain resources, that is, PUCCH1 resources and PUCCH2 resources, where PUCCH1 resources are used for transmitting HARQ information and CSI corresponding to downlink TRP1 transmission, and PUCCH2 resources are used for transmitting HARQ information and CSI corresponding to downlink TRP2 transmission, codebook transmission with rank of 2 may be adopted for PUCCH1 resources and PUCCH2 resources.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource.

Note that, in this embodiment, the target TPMI may also be used to transmit the at least two first PUCCH resources when there is at least a partial overlap between the time domain resources or the frequency domain resources of the at least two first PUCCH resources.

In this embodiment, when the time domain resources of at least two first PUCCH resources are completely orthogonal and the frequency domain resources are completely orthogonal, and the PUCCH formats of at least two first PUCCH resources include any one of format 0, format 1 and format 4, the at least two first PUCCH resources may be transmitted in a code division multiplexing manner.

For example, as shown in fig. 14, for Multi-TRP transmission, if two PUCCH resources, namely, PUCCH1 resources and PUCCH2 resources, which are completely orthogonal to each other in time domain and frequency domain resources, are configured on the network side, wherein the PUCCH1 resources (wherein the PUCCH format of the PUCCH1 resources is format 0) are used for transmitting HARQ information and CSI corresponding to downlink TRP1 transmission, and the PUCCH2 resources (wherein the PUCCH format of the PUCCH2 resources is format 0) are used for transmitting HARQ information and CSI corresponding to downlink TRP2 transmission, the PUCCH1 resources and PUCCH2 resources may be transmitted in a code division multiplexing manner.

The PUCCH1 resource and the PUCCH2 resource are the first PUCCH resource.

Optionally, the transmitting the at least two first PUCCH resources by using a code division multiplexing manner includes: the UCI carried by the at least two first PUCCH resources is transmitted using different cyclic shifts or different orthogonal superposition codes.

In this embodiment, for UCI carried by at least two first PUCCH resources, different Cyclic shifts (i.e. Cyclic Shift) or different orthogonal superposition codes (Orthogonal Cover Code, OCC) may be used for transmission. For example, UCI carried by PUCCH1 resources adopts first cyclic shift transmission, UCI carried by PUCCH2 resources adopts second cyclic shift transmission, wherein the first cyclic shift and the second cyclic shift are different; or the UCI carried by the PUCCH1 resource is transmitted by adopting a first orthogonal superposition code, and the UCI carried by the PUCCH2 resource is transmitted by adopting a second orthogonal superposition code, wherein the first positive overlapping addition code and the second positive overlapping addition code are different.

Optionally, the transmitting the at least two first PUCCH resources by using a code division multiplexing manner includes: the demodulation reference signals (DMRS) borne by the at least two first PUCCH resources are transmitted by adopting different cyclic shifts or different orthogonal superposition codes.

In this embodiment, for the demodulation reference signals (Demodulation Reference Signal, DMRS) carried by at least two first PUCCH resources, different cyclic shifts or different orthogonal superposition code transmissions may also be used. For example, the at least two first PUCCH resources include a PUCCH1 resource and a PUCCH2 resource, the DMRS carried by the PUCCH1 resource employs a first cyclic shift transmission, and the DMRS carried by the PUCCH2 resource employs a second cyclic shift transmission, where the first cyclic shift and the second cyclic shift are different; or the DMRS borne by the PUCCH1 resource is transmitted by adopting a first orthogonal superposition code, and the DMRS borne by the PUCCH2 resource is transmitted by adopting a second orthogonal superposition code, wherein the first positive overlapping addition code and the second positive overlapping addition code are different.

It should be noted that, the UCI and the DMRS carried by the at least two first PUCCH resources may be transmitted in different code division multiplexing manners, for example, UCI carried by the at least two first PUCCH resources is transmitted by different cyclic shifts, and DMRS carried by the at least two first PUCCH resources is transmitted by different orthogonal superposition codes.

Optionally, in a case that the terminal device does not support simultaneous transmission of at least two PUCCH resources, the target PUCCH resource is a PUCCH resource determined based on the association relationship.

In this embodiment, when the terminal device does not support simultaneous transmission of at least two PUCCH resources, the target PUCCH resource may be determined based on an association relationship of at least two first PUCCH resources, so as to ensure transmission of UCI.

It should be noted that, the manner of determining the target PUCCH resource based on the association relationship of at least two first PUCCH resources may be referred to the related description of the foregoing embodiment, and this embodiment is not described herein in detail.

Optionally, in a case that the terminal device supports simultaneous transmission of at least two PUCCH resources, the target PUCCH resource is the at least two first PUCCH resources that are simultaneously transmitted.

In this embodiment, when the terminal device supports simultaneous transmission of at least two PUCCH resources, at least two first PUCCH resources may be simultaneously transmitted at this time, so that the UCI may be simultaneously transmitted by directly using the at least two first PUCCH resources, so as to ensure fast transmission of UCI.

In summary, according to the transmission method provided by the embodiment of the invention, when Multi-TRP is transmitted and HARQ information and CSI are fed back simultaneously in the uplink, all or part of the HARQ information and the CSI corresponding to the downlink transmission can be transmitted in PUCCH resources, so that PUCCH resource conflict can be avoided, HARQ information transmission can be ensured preferentially, and downlink transmission performance is improved.

Or the first PUCCH resource set is configured through the high-level signaling, and the second PUCCH resource set is indicated to the terminal equipment through DCI, so that the terminal equipment can select PUCCH resources from the second PUCCH resources to carry out target UCI transmission. The PUCCH resources in the second PUCCH resource set belong to the first PUCCH resource set, that is, the second PUCCH resource set is composed of at least part of the PUCCH resources in the first PUCCH resource set.

Note that, in the case of indicating the PUCCH resource set by DCI, each PUCCH resource indication field value may correspond to at least one two PUCCH resources, and each PUCCH resource indication field may correspond to at least one PUCCH resource indication field value.

In another embodiment, in case that the PUCCH resource set is indicated by DCI, each PUCCH resource indication field may correspond to at least two PUCCH resource indication field values, i.e. each PDSCH transmission may correspond to at least two PUCCH resource indication field values. At this time, each PUCCH resource indication field value may correspond to one or at least two PUCCH resources.
