[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on December 18, 2023, with application number 202311751253.8 and invention name “Method, terminal and network side device for transmitting HARQ-ACK information”. The entire contents of the Chinese patent application are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of communication technology, and specifically to a method, terminal, and network-side device for transmitting Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information. Background Art

[0004] When deploying traditional cellular networks, frequency division duplex (FDD) or time division duplex (TDD) can be used, depending on the available spectrum and service characteristics. In FDD, uplink and downlink transmissions occur on different frequencies, preventing interference and allowing simultaneous transmission. In TDD, uplink and downlink transmissions occur on the same frequency, interleaved using time division.

[0005] In order to more flexibly utilize limited spectrum resources to dynamically match business needs, improve resource utilization efficiency, and enhance uplink coverage, latency, and other performance of data transmission, related technologies have proposed a flexible duplexing method based on non-overlapping sub-bands in the frequency domain, namely Subband Full Duplex (SBFD). In SBFD, full duplex is implemented on the network side, and half duplex or full duplex is implemented on the terminal side.

It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0036] To facilitate the description of the following solution, the following concepts and explanations are given first:

[0037] Based on the TDD pattern configuration information provided by the network to the terminal, for example, the TDD-UL-DL-ConfigurationCommon or TDD-UL-DL-ConfigurationDedicated provided for a serving cell of the terminal, the following symbol types can be distinguished:

[0038] 1) Downlink symbol (DL symbol).

[0039] 2) Uplink symbol (UL symbol).

[0040] 3) Flexible symbol.

[0041] When tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated is not provided for a certain serving cell, each symbol may be considered as a Flexible symbol, or may follow the rules corresponding to the Flexible symbol.

[0042] Based on the preceding TDD pattern configuration information and the SBFD configuration information provided by the network to the terminal, the following symbol types can be further distinguished:

[0043] 4)SBFD symbol.

[0044] The network side can configure certain symbols to perform SBFD operations through SBFD configuration information, that is, configure these symbols as SBFD symbols. For example, some or all symbols within a single cycle determined based on the TDD pattern are configured as SBFD symbols. These symbols configured as SBFD symbols can be some or all of the symbol types distinguished based on the TDD pattern configuration information.

[0045] For a serving cell configured or activated for a terminal, the SBFD symbol on the serving cell can be further distinguished by the following symbol types:

[0046] a: SBFD symbol for duplex mode 1. For duplex mode 1, the network side supports full-duplex SBFD operation; the terminal side only supports half-duplex SBFD operation. That is, within a single SBFD symbol, the terminal can only perform uplink transmission or downlink reception, and cannot perform FDM-based uplink transmission and downlink reception simultaneously.

[0047] b: SBFD symbol for duplex mode 2. For Duplex mode 2, the network side supports full-duplex-based SBFD operation; the terminal side can support full-duplex-based SBFD operation, that is, the terminal can simultaneously perform FDM-based uplink transmission and downlink reception within a single SBFD symbol. It can be understood that a terminal that supports full-duplex-based SBFD operation (that is, supports Duplex mode 2, or supports the SBFD symbol for duplex mode 2) must also support half-duplex-based SBFD operation (that is, supports Duplex mode 1, or supports the SBFD symbol for duplex mode 1).

[0048] 5) Non-SBFD symbol.

[0049] A symbol that is not configured (or instructed) to perform an SBFD operation is considered a non-SBFD symbol.

[0050] Optionally, when the network side configures the time domain unit that can perform SBFD operations through SBFD configuration information, the configuration granularity can also be a time domain granularity of a time slot or other predefined duration. There is no restriction here, and it is uniformly described as distinguishing the Symbol type, that is, the Symbol type is used to distinguish the type of time domain unit, which does not limit the specific time domain granularity.

[0051] In the related art, different Symbol types (for example, SBFD symbol and non-SBFD symbol, or SBFD symbol for duplex mode 1, SBFD symbol for duplex mode 2 and non-SBFD symbol) distinguished based on SBFD configuration information can be configured separately (directly), or the corresponding physical uplink control channel (PUCCH) parameters, such as PUCCH-Config, PUCCH resource set (PUCCH-ResourceSet), PUCCH resource (PUCCH-Resource) and other configuration parameters, can be derived separately (based on the frequency domain offset, their respective starting reference points, etc.) to consider / compensate for possible differences in antenna and RF configurations, interference conditions and restrictions corresponding to different Symbol types.

[0052] Below, in conjunction with the accompanying drawings, the HARQ-ACK information transmission method provided in the embodiment of the present application is described in detail through some embodiments and their application scenarios.

[0053] As shown in Figure 2, an embodiment of the present application provides a method 200 for transmitting HARQ-ACK information, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method can be applied to a carrier or cell configured with SBFD information. The terminal is scheduled to transmit multiple HARQ-ACK information within a time unit. The method includes the following steps.

[0054] S202: The terminal performs a first operation, where the first operation is used to transmit at least one HARQ-ACK information among multiple HARQ-ACK information. The first operation includes at least one of the following: determining a transmission method for the multiple HARQ-ACK information; and determining a time domain type corresponding to the multiple HARQ-ACK information.

[0055] In some embodiments of the present application, the above-mentioned carrier may be a TDD carrier; the cell may be a cell where a physical uplink control channel (PUCCH) is located, such as a Pcell or a PUCCH-sSCell.

[0056] In some embodiments of the present application, the above-mentioned HARQ-ACK information may include at least one of a HARQ confirmation response or a HARQ negative response.

[0057] The time domain type mentioned in the various embodiments of the present application may be a symbol type or a time slot type, etc.; a time unit may be a symbol, a time slot, a sub-time slot, etc. Considering that HARQ-ACK information can be multiplexed on a physical uplink shared channel (PUSCH), the above-mentioned time unit may be not only a PUCCH time unit but also a PUSCH time unit, etc. Optionally, the time domain type mentioned in the various embodiments of the present application includes an SBFD type or a non-SBFD type, for example, an SBFD symbol (for example, it may include at least one of the above-mentioned SBFD symbol for duplex mode 1 and SBFD symbol for duplex mode 2), a non-SBFD symbol.

[0058] Optionally, in some embodiments of the present application, the priorities corresponding to the multiple HARQ-ACK information are the same; or the downlink transmission types (such as unicast downlink transmission, multicast downlink transmission) corresponding to the multiple HARQ-ACK information are the same; or, the multiple HARQ-ACK information include delayed HARQ-ACK (Deferred HARQ-ACK) information.

[0059] In this embodiment, determining the transmission mode of the multiple HARQ-ACK information includes, for example, determining to multiplex the multiple HARQ-ACK information into one codebook for transmission, and for example, constructing codebook transmissions separately according to different time domain types.

[0060] In some embodiments of the present application, among the multiple HARQ-ACK information, at least two HARQ-ACK information correspond to different time domain types. Therefore, it is necessary to determine the time domain types corresponding to the multiple HARQ-ACK information. Determining the time domain types corresponding to the multiple HARQ-ACK information can be used to determine the transmission mode of the multiple HARQ-ACK information, or determine the PUCCH resources used to transmit the HARQ-ACK information and its transmission parameters (such as power, beam information), etc.

[0061] The HARQ-ACK transmission method provided in an embodiment of the present application, when a terminal is scheduled to transmit multiple HARQ-ACK information within a time unit, the terminal performs a first operation, and the first operation is used to transmit at least one HARQ-ACK information among the multiple HARQ-ACK information. The first operation includes at least one of the following: determining the transmission mode of the multiple HARQ-ACK information; determining the time domain type corresponding to the multiple HARQ-ACK information. Through the first operation performed by the terminal, the transmission of HARQ-ACK information can be performed in a carrier or cell configured with SBFD information, which can improve the effectiveness of HARQ-ACK information feedback, thereby improving the transmission performance of PDSCH and improving the effectiveness of the communication system.

[0062] In one embodiment, determining the transmission mode of the multiple HARQ-ACK information in embodiment 200 includes: determining to multiplex the multiple HARQ-ACK information in one codebook for transmission; wherein the multiple HARQ-ACK information is first HARQ-ACK information, the first HARQ-ACK information is HARQ-ACK information with corresponding downlink control information (Downlink Control Information, DCI), and the time domain types corresponding to the multiple first HARQ-ACK information indicated by the DCI are the same; or, the multiple HARQ-ACK information is second HARQ-ACK information, the second HARQ-ACK information is HARQ-ACK information without corresponding DCI, and the time domain types corresponding to the multiple HARQ-ACK information are the same.

[0063] In this embodiment, the multiple HARQ-ACKs may be HARQ-ACKs including corresponding DCI, such as HARQ-ACKs for PDSCHs corresponding to scheduled DCIs, HARQ-ACK feedback is required and HARQ-ACKs corresponding to PDCCHs that do not schedule PDSCHs (such as PDCCHs indicating TCI updates, PDCCHs indicating Scell ​​dormancy, and PDCCHs that trigger type 3 codebooks). The terminal multiplexes multiple HARQ-ACKs in one codebook for transmission, and the terminal expects that the time domain types corresponding to the HARQ-ACK transmissions indicated by all DCIs are consistent.

[0064] In this embodiment, the multiple HARQ-ACKs may be HARQ-ACKs for which no corresponding DCI exists (for example, HARQ-ACKs for SPS PDSCH (optionally, including the first PDSCH after SPS PDSCH is activated)). The terminal multiplexes the multiple HARQ-ACKs in one codebook for transmission, and the terminal expects that the time domain types corresponding to all HARQ-ACK information are consistent.

[0065] In some embodiments, HARQ-ACK information with corresponding DCI can be understood as HARQ-ACK information corresponding to DG PDSCH or PDCCH; HARQ-ACK information without corresponding DCI can be understood as HARQ-ACK information corresponding to SPS PDSCH.

[0066] In one embodiment, the multiple HARQ-ACK information in embodiment 200 includes first HARQ-ACK information and second HARQ-ACK information, where the first HARQ-ACK information is HARQ-ACK information with corresponding DCI, and the second HARQ-ACK information is HARQ-ACK information without corresponding DCI. Determining the transmission mode of the multiple HARQ-ACK information includes at least one of the following:

[0067] 1) Multiplexing the second HARQ-ACK information and the first HARQ-ACK information into a first codebook for transmission.

[0068] 2) Multiplexing the first HARQ-ACK information and the HARQ-ACK information in the second HARQ-ACK information with the same time domain type as that corresponding to the first HARQ-ACK information into a first codebook for transmission.

[0069] 3) discarding HARQ-ACK information in the second HARQ-ACK information that has a different time domain type from that corresponding to the first HARQ-ACK information.

[0070] 4) A second codebook is constructed separately for the HARQ-ACK information in the second HARQ-ACK information and the HARQ-ACK information corresponding to the first HARQ-ACK information, and a method for separately constructing a codebook can refer to the description of the following embodiments.

[0071] For example, in this embodiment, the terminal expects that the time domain type corresponding to the second HARQ-ACK information is the same as the time domain type corresponding to the first HARQ-ACK information, and the terminal multiplexes the second HARQ-ACK information and the first HARQ-ACK information in a first codebook for transmission.

[0072] In this embodiment, for example, the time domain type corresponding to the second HARQ-ACK information is the same as or different from the time domain type corresponding to the first HARQ-ACK information, and the terminal multiplexes the second HARQ-ACK information and the first HARQ-ACK information in a first codebook for transmission.

[0073] For another example of this embodiment, the time domain type corresponding to the first part of the HARQ-ACK information in the second HARQ-ACK information is the same as the time domain type corresponding to the first HARQ-ACK information; the time domain type corresponding to the second part of the HARQ-ACK information is different from the time domain type corresponding to the first HARQ-ACK information; the terminal can multiplex the first HARQ-ACK information and the first part of the HARQ-ACK information in the second HARQ-ACK information in a first codebook for transmission; discard the second part of the second HARQ-ACK information, or construct a second codebook separately for the second part of the second HARQ-ACK information.

[0074] In the case where the second HARQ-ACK information and the first HARQ-ACK information are multiplexed and transmitted in a first codebook, this embodiment may further include the following steps: determining a PUCCH resource based on a time domain type corresponding to the first HARQ-ACK information, and the PUCCH resource is used to transmit the first HARQ-ACK information and part or all of the second HARQ-ACK information.

[0075] Optionally, the DCI includes indication information, where the indication information is used to indicate the time domain type corresponding to at least part of the HARQ-ACK information in the first HARQ-ACK information, and the time domain type indicated by the indication information is the same as the time domain type configured or indicated by the time unit.

[0076] In this embodiment, some DCI formats (such as non-fallback DCI) include the indication information, and some DCI formats (such as fallback DCI, DCI format 1_0) include indication information. For DCI without the indication information, the time domain type corresponding to its HARQ-ACK information can be a high-level configuration or predefined or determined according to predefined rules.

[0077] In some embodiments, the DCI indicates the time domain type corresponding to the first HARQ-ACK information, and the indication method may be with a corresponding indication field or without a corresponding indication field, but through an implicit method, for example, through an implicit indication such as a scrambling code of a demodulation reference signal (DMRS) or a control channel element (CCE) index.

[0078] In this embodiment, the first HARQ-ACK information is HARQ-ACK information with corresponding DCI. If the DCI includes an indication field for indicating the time domain type corresponding to the first HARQ-ACK information, the terminal expects that the time domain type indicated by the DCI is consistent with the time domain type configured or indicated in the time unit where the terminal transmits the HARQ-ACK (such as the signaling configuration used to configure or indicate SBFD configuration information or the time domain type indicating the time unit where the HARQ-ACK is located).

[0079] In one embodiment, determining the transmission mode of the multiple HARQ-ACK information in embodiment 200 includes: determining that the multiple HARQ-ACK information is multiplexed in a codebook for transmission; determining the time domain type corresponding to the multiple HARQ-ACK information includes: determining the time domain type corresponding to the multiple HARQ-ACK information after multiplexing according to the time domain type indicated by the last DCI in the DCI corresponding to the multiple HARQ-ACK information.

[0080] In this embodiment, the terminal multiplexes multiple HARQ-ACKs into one codebook for transmission, and the terminal determines the time domain type corresponding to the HARQ-ACK information according to the time domain type indicated by the last DCI.

[0081] Optionally, the last DCI is the last DCI of multiple DCIs, and the multiple DCIs include the DCI corresponding to the multiple HARQ-ACK information. The determination method of the last DCI can be the same as the determination method of the DCI corresponding to the PUCCH resource for feedback of the multiple HARQ-ACK information in the prior art (for example, for all DCIs scheduled for transmission of the corresponding HARQ-ACK in the PUCCH time domain unit, sort in ascending order of the serving cell index and the PDCCH monitoring occasion in ascending order, the last DCI, optionally, if the same PDCCH monitoring in the same serving cell occasion, there are multiple DCIs, then the DCI of the PDCCH in the first CORESET is arranged before the DCI of the PDCCH of the second CORESET); or, the last DCI is the last DCI in the DCI containing indication information (for example, the last DCI obtained by sorting the DCI with indication information in the multiple DCIs according to a certain rule (which may be the same as the above method)), and the indication information is used to indicate the time domain type corresponding to the HARQ-ACK information; or, the last DCI is the last DCI in the DCI corresponding to the downlink transmission with HARQ-ACK feedback enabled (for example, the last DCI obtained by sorting the DCI with corresponding HARQ-ACK enabled in the multiple DCIs according to a certain rule (which may be the same as the above method)).

[0082] In one embodiment, determining the transmission mode of the multiple HARQ-ACK information in embodiment 200 includes: determining to multiplex the multiple HARQ-ACK information into one codebook for transmission; and determining the time domain type corresponding to the multiple HARQ-ACK information includes one of the following:

[0083] 1) Determine, according to an indication corresponding to a target semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), a time domain type corresponding to the multiple HARQ-ACK information after multiplexing, the target SPS PDSCH being one of the SPS PDSCHs corresponding to the multiple HARQ-ACK information.

[0084] Optionally, the target SPS PDSCH is: the SPS PDSCH corresponding to the multiple HARQ-ACK information with the smallest configuration index or the latest transmission time.

[0085] In this embodiment, the terminal multiplexes multiple HARQ-ACKs in one codebook for transmission, and the terminal determines the time domain type corresponding to the multiplexed HARQ-ACK information according to an indication corresponding to one of the SPS PDSCHs corresponding to the multiple HARQ-ACK information, for example, the SPS PDSCH with the smallest configuration index (index) and the last SPS PDSCH transmission time.

[0086] 2) Determine the time domain type corresponding to the multiple HARQ-ACK information after multiplexing according to predefined or high-level configuration.

[0087] In this embodiment, the terminal multiplexes multiple HARQ-ACKs into one codebook for transmission, and the terminal determines the time domain type corresponding to the multiplexed HARQ-ACK information according to a predefined or high-level configuration.

[0088] In one embodiment, determining the transmission mode of the multiple HARQ-ACK information in embodiment 200 includes: determining to construct codebooks respectively according to different time domain types corresponding to the multiple HARQ-ACK information, which may specifically include: multiplexing third HARQ-ACK information among the multiple HARQ-ACK information in the first codebook, where the third HARQ-ACK information is HARQ-ACK information whose corresponding time domain type is SBFD time domain type among the multiple HARQ-ACK information; and multiplexing fourth HARQ-ACK information among the multiple HARQ-ACK information in the second codebook, where the fourth HARQ-ACK information is HARQ-ACK information whose corresponding time domain type is non-SBFD time domain type among the multiple HARQ-ACK information.

[0089] In this embodiment, the terminal constructs codebooks according to the time domain type corresponding to each HARQ-ACK information, SBFD and non-SBFD, and determines PUCCH resources respectively. If the PUCCH resources do not overlap, they are transmitted separately; if the PUCCH resources overlap, they are multiplexed in the PUCCH resources corresponding to one of the symbol types, or one type of codebook is discarded.

[0090] Specifically, with respect to the embodiment of the first codebook and the second codebook mentioned above, the method further includes: determining PUCCH resources based on the first codebook and the second codebook respectively.

[0091] When PUCCH resources are determined based on the first codebook and the second codebook, respectively, this embodiment satisfies at least one of the following:

[0092] 1) The respectively determined PUCCH resources do not overlap, and the method further includes: transmitting the first codebook and the second codebook respectively based on the determined PUCCH resources. In this embodiment, the terminal does not expect the two PUCCHs to overlap with the same PUSCH.

[0093] 2) The respectively determined PUCCH resources do not overlap with the same PUSCH resource. In this embodiment, the terminal does not expect the two PUCCHs to overlap with the same PUSCH.

[0094] 3) The respectively determined PUCCH resources overlap with the same PUSCH resource, and the method further includes: concatenating the first codebook and the second codebook and multiplexing them in the PUSCH for transmission; or multiplexing the first codebook and the second codebook in the PUSCH for transmission, the first codebook and the second codebook being encoded separately; or discarding one of the first codebook and the second codebook, and multiplexing the non-discarded codebook in the PUSCH resource for transmission.

[0095] 4) The respectively determined PUCCH resources overlap, and the method further includes: multiplexing the first codebook and the second codebook into one PUCCH resource for transmission; or discarding one of the first codebook and the second codebook and transmitting the codebook that is not discarded.

[0096] In one embodiment, determining the transmission method of the multiple HARQ-ACK information in embodiment 200 includes: determining to multiplex the multiple HARQ-ACK information in a codebook for transmission; the method also includes: determining PUCCH resources and transmission parameters based on the time domain type of the time unit, and the PUCCH resources are used to transmit the multiple HARQ-ACK information.

[0097] In this embodiment, the terminal multiplexes multiple HARQ-ACKs into one codebook for transmission, and determines PUCCH resources and transmission parameters according to the time domain type of the current PUCCH time unit.

[0098] For cases where the terminal does not need to determine the starting symbol and symbol position of the PUCCH according to the time domain type, for example, for SBFD and non-SBFD PUCCH transmissions, the time domain resource configuration is common or the same, or for SBFD and non-SBFD PUCCH transmissions, the terminal multiplexes multiple HARQ-ACK information in one codebook for transmission, and determines the PUCCH resources and transmission parameters according to the time domain type corresponding to the current PUCCH resources.

[0099] To illustrate in detail the method for transmitting HARQ-ACK information provided in an embodiment of the present application, two specific embodiments will be described below.

[0100] The following two embodiments are described by taking the time domain type being the symbol type and the time unit being the time slot as an example.

[0101] Example 1

[0102] In this embodiment, after the Symbol type corresponding to the HARQ-ACK information is determined, the corresponding PUCCH resource is determined based on the Symbol type within the PUCCH slot, and PUCCH transmission is performed according to the transmission parameters corresponding to the Symbol type. For example, the base station configures the PUCCH resource, power control parameters for PUCCH transmission, beam information related parameters, etc. for the terminal in SBFD symbols and non-SBFD transmission PUCCH respectively.

[0103] As shown in Figure 3, assume that a TDD pattern period contains five slots and uses a DDDUU configuration, where the second and third D slots are configured as SBFD slots.

[0104] Assume that the base station configures the Symbol type corresponding to its HARQ-ACK information feedback per SPS-Config, or determines the Symbol type corresponding to its HARQ-ACK information feedback based on the SPS activation DCI. Since the SPS PDSCH is sent periodically, in a certain uplink time slot, the terminal may feedback the HARQ-ACK information of different SPS PDSCHs, and the corresponding Symbol types indicated by the configured / activated DCI may be different. For example, in Figure 3, according to the indication of the activation DCI, the terminal feeds back the HARQ-ACK information of SPS1, SPS2, and SPS 3 in time slot 4. And the HARQ-ACK Symbol type corresponding to the activation DCI indication of SPS1, SPS2, and SPS 3 is different. Assume that SPS1 corresponds to non-SBFD, and SPS 2 and SPS 3 correspond to SBFD. At this time, the terminal can execute as follows:

[0105] Mode 1: The terminal expects that the Symbol type corresponding to all HARQ-ACK information is consistent, that is, the terminal should avoid the above scenario during configuration / activation.

[0106] Method 2: The terminal multiplexes multiple HARQ-ACK information into a single codebook for transmission, and determines the symbol type of the multiplexed HARQ-ACK based on the indication corresponding to one of the SPSs corresponding to the multiple HARQ-ACK information, such as the SPS with the smallest configuration index and the SPS with the latest PDSCH transmission time. This method ensures that different types of HARQ-ACK can be fed back and simplifies the design.

[0107] In mode 2, the terminal can multiplex HARQ-ACK information of different symbol types on a single channel for transmission. Optionally, the terminal can also encode HARQ-ACK information of different symbol types separately, and then use different code rates for transmission according to different symbol types to meet different reliability requirements and save uplink transmission resources.

[0108] Method 3: The terminal multiplexes multiple HARQ-ACK information into one codebook for transmission, and determines the Symbol type of the multiplexed HARQ-ACK information based on predefined / high-layer configuration. For example, among the multiple HARQ-ACK information, as long as non-SBFD type HARQ-ACK information is included, the Symbol type of the multiplexed HARQ-ACK information is determined to be non-SBFD type. This method can ensure the reliability of HARQ-ACK feedback and ensure that different types of HARQ-ACK can be fed back.

[0109] Mode 4: The terminal constructs codebooks according to the symbol type corresponding to each SPS PDSCH, SBFD and non-SBFD respectively, and determines the PUCCH resources respectively. If there is no overlap, they are transmitted separately; if there is overlap, they are multiplexed in the PUCCH resources corresponding to one of the symbol types, or one of the codebook types is discarded.

[0110] Mode 5: The terminal multiplexes multiple HARQ-ACK information in one codebook for transmission, and determines the PUCCH resources and transmission parameters according to the symbol type of the current PUCCH time unit. For example, in Figure 3, slot 4 is a non-SBFD time slot, then the terminal feeds back the HARQ-ACK information of SPS1, SPS2, and SPS 3 together, and determines the corresponding PUCCH resources according to non-SBFD (for example, using the PUCCH resource configuration corresponding to the SBFD time domain type to determine the PUCCH resources corresponding to the HARQ-ACK feedback) and transmission.

[0111] Example 2

[0112] As shown in Figure 4, PDSCH 1, PDSCH 2, and PDSCH 3 are respectively scheduled by non-fallback DCI (for example, DCI format 1_1 or 1_2), fallback DCI (for example, DCI format 1_0), and non-fallback DCI, and their HARQ-ACK information is all indicated to be fed back in slot 4. Assume that the Symbol type protocol corresponding to the HARQ-ACK information scheduled by fallback DCI is predetermined to be non-SBFD type. Non-fallback DCI contains an indication field for indicating the Symbol type corresponding to its HARQ-ACK information feedback. It is possible that the Symbol types corresponding to the above three HARQ-ACK information are different. At this time, the terminal can adopt the following methods:

[0113] Mode 1: The terminal multiplexes multiple HARQ-ACK information in one codebook for transmission and the terminal expects the Symbol type indicated by all DCI to be consistent, that is, the base station should avoid scenarios with different Symbol types. That is, the non-fallback indication should be consistent with the HARQ-ACK corresponding to the fallback DCI. The terminal multiplexes the multiple HARQ-ACKs together and determines the PUCCH resource transmission according to the Symbol type corresponding to the HARQ-ACK information with DCI (optionally, the time slot can also have HARQ-ACK feedback of SPS PDSCH at this time, regardless of the type of SPS HARQ-ACK).

[0114] Mode 2: The terminal multiplexes multiple HARQ-ACK information into one codebook for transmission, and determines the Symbol type corresponding to the HARQ-ACK information based on the Symbol type indicated by the last DCI.

[0115] Optionally, the last DCI is the last DCI among multiple DCIs, and the multiple DCIs are DCIs corresponding to the multiple HARQ-ACKs. The method for determining the last DCI may be the same as the method for determining the PRI DCI corresponding to the PUCCH resource for feedback of the multiple HARQ-ACK information (for example, for all DCIs scheduled for transmission of the corresponding HARQ-ACK in the PUCCH time domain unit, sort them in ascending order of the service cell index and the PDCCH monitoring occasion, and the last DCI, optionally, if there are multiple DCIs in the same PDCCH monitoring occasion of the same service cell, the DCI of the PDCCH in the first CORESET is ranked before the DCI of the PDCCH of the second CORESET).

[0116] Alternatively, the last DCI is the last DCI in the DCI including indication information, where the indication information is used to indicate the time domain type corresponding to the HARQ-ACK information, that is, the non-fallback DCI in this embodiment.

[0117] Alternatively, the last DCI is the last DCI in the DCI corresponding to downlink transmission with HARQ-ACK feedback enabled.

[0118] In addition, assuming that only the HARQ-ACK information of PDSCH1 and PDSCH2 is indicated in slot 4 feedback (no PDSCH3), the last DCI is the DCI corresponding to PDSCH 2. Since the DCI corresponding to PDSCH2 is fallback DCI and does not include the Symbol type indication field, the last DCI in the DCI including the Symbol type indication field is the DCI corresponding to PDSCH1.

[0119] Mode 3: The terminal constructs codebooks according to the Symbol type corresponding to each HARQ-ACK information, and determines PUCCH resources separately according to SBFD and non-SBFD. If the PUCCH resources do not overlap, they are transmitted separately; if the PUCCH resources overlap, they are multiplexed in the PUCCH resources corresponding to one of the symbol types, or one of the codebook types is discarded.

[0120] Method 4: The terminal multiplexes multiple HARQ-ACK messages into a single codebook for transmission and determines the PUCCH resource and transmission parameters based on the symbol type of the current PUCCH time unit. For example, in Figure 4, slot 4 is a non-SBFD time slot. The terminal then feeds back the HARQ-ACK information for all three PDSCHs and determines the corresponding PUCCH resource and transmission parameters based on non-SBFD.

[0121] It should be noted that in Methods 2 and 4 above, for some HARQ-ACK information, the time domain type used to determine the HARQ-ACK feedback timing may differ from the time domain type corresponding to the HARQ-ACK information transmission. Specifically, because the k1 set and sub-slot information are configured in the PUCCH-config, if the k1 set and sub-slot information are configured separately in the PUCCH-config corresponding to different time domain types, the terminal can only determine the k1 set and sub-slot after determining the corresponding PUCCH-config. For each HARQ-ACK information feedback, if the terminal determines the PUCCH feedback time unit based on the corresponding HARQ-ACK feedback timing (which may be related to the symbol type), if multiple HARQ-ACKs need to be fed back within the feedback time unit, then applying Methods 2 and 4 above may result in scenarios where the symbol type used to determine the HARQ-ACK feedback timing differs from the symbol type corresponding to the HARQ-ACK transmission.

[0122] In another embodiment, the terminal does not expect a scenario in which the Symbol type corresponding to the HARQ-ACK information indicated by the DCI is different from the Symbol type corresponding to the time domain unit where the HARQ-ACK is transmitted.

[0123] The above describes in detail the method for transmitting HARQ-ACK information according to an embodiment of the present application in conjunction with Figures 2 to 4.
