[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 18, 2023, with application number 202311751275.4 and application name “SPS HARQ-ACK transmission method, terminal and network side equipment”. The entire contents of the application are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a transmission method, terminal and network-side device for Semi-Persistent Scheduling (SPS) Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK). 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] To more flexibly utilize limited spectrum resources to dynamically match service needs, improve resource utilization efficiency, and enhance uplink coverage, latency, and other performance, a flexible duplexing scheme based on non-overlapping frequency sub-bands, known as Subband Full Duplex (SBFD), has been proposed. In SBFD, full duplex is implemented on the network side, while half 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] In an SBFD symbol, the frequency domain of a single carrier can be semi-statically divided into three subbands. For example, the two sides of the carrier are downlink subbands, and the center is an uplink subband; for another example, the two sides of the carrier are uplink subbands, and the center is a downlink subband.

[0045] 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.

[0046] 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:

[0047] 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.

[0048] 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).

[0049] 5) Non-SBFD symbol.

[0050] A symbol that is not configured (or instructed) to perform an SBFD operation is considered a non-SBFD symbol.

[0051] 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.

[0052] In the related art, for 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, 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 configured (directly) or derived (implicitly based on frequency domain offset, 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.

[0053] The following, in conjunction with the accompanying drawings, describes in detail the SPS HARQ-ACK transmission method provided in the embodiments of the present application through some embodiments and their application scenarios.

[0054] As shown in FIG2 , an embodiment of the present application provides a method 200 for transmitting an SPS HARQ-ACK. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0055] S202: The terminal performs a first operation, where the first operation is used to perform delayed transmission of SPS HARQ-ACK on a carrier or cell configured with SBFD, and the first operation includes at least one of the following: determining a time domain type corresponding to the SPS HARQ-ACK; triggering delayed transmission of the SPS HARQ-ACK; and determining a target PUCCH time domain unit, where the target PUCCH time domain unit is used to transmit the delayed SPS HARQ-ACK (Deferred SPS HARQ-ACK).

[0056] The carrier mentioned in this embodiment may be a TDD carrier; the cell may be a cell where a physical uplink control channel (PUCCH) is located, that is, a serving cell that can be used to transmit the PUCCH.

[0057] The SPS HARQ-ACK in this embodiment is the HARQ-ACK corresponding to the SPS PDSCH transmission, or the HARQ-ACK fed back by the terminal in response to the SPS PDSCH transmission, which may include at least one of an SPS HARQ confirmation response or an SPS HARQ negative response.

[0058] The time domain type mentioned in the various embodiments of the present application may be a symbol type; the time domain unit may be a time slot, a sub-time slot, etc.; the sub-time domain unit may be a symbol, etc. For example, the target PUCCH time domain unit may be a target PUCCH time slot, and the sub-time domain unit within the target PUCCH time domain unit may be a symbol within the target PUCCH time slot. 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.

[0059] In this embodiment, the time domain type corresponding to the SPS HARQ-ACK is determined, which can be used to determine whether to trigger the delayed transmission of the SPS HARQ-ACK, and can also be used to determine the target PUCCH time domain unit. For details, please refer to the delay triggering criteria and target PUCCH time domain unit determination criteria below.

[0060] In this embodiment, the delayed transmission mechanism of SPS HARQ-ACK can be simply described as follows: when the HARQ-ACK transmission of the SPS physical downlink shared channel (PDSCH) (for example, in the initial PUCCH time slot) is about to be discarded because it overlaps with an invalid sub-time domain unit (such as an invalid symbol), the terminal delays the reporting of SPS HARQ-ACK based on predefined rules until a target PUCCH time domain unit (such as Target PUCCH slot) that meets the predefined requirements is found, and these delayed SPS HARQ-ACKs (Deferred SPS HARQ-ACK) are reported in this target PUCCH time domain unit. By introducing the delayed transmission mechanism of SPS HARQ-ACK, unnecessary SPS HARQ-ACK discards can be avoided to a large extent, thereby improving the transmission performance of SPS PDSCH.

[0061] The SPS HARQ-ACK transmission method provided in an embodiment of the present application is characterized in that the terminal performs a first operation, and the first operation includes at least one of the following: determining the time domain type corresponding to the SPS HARQ-ACK; triggering delayed transmission of the SPS HARQ-ACK; and determining a target PUCCH time domain unit, wherein the target PUCCH time domain unit is used to transmit the delayed SPS HARQ-ACK. Through the first operation performed by the terminal, delayed transmission of the SPS HARQ-ACK can be performed on a carrier or cell configured with SBFD, which is beneficial to improving the probability of successful transmission of the SPS HARQ-ACK, thereby improving the transmission performance of the SPS PDSCH.

[0062] In some embodiments, the time domain type applied by the SPS HARQ-ACK during the delay process can be adjusted based on predefined rules, as shown in the second embodiment below, so as to facilitate determining a target PUCCH time domain unit with a time domain position as close as possible to the front, thereby shortening the SPS HARQ-ACK feedback delay.

[0063] The following will first introduce how to determine the time domain type corresponding to SPS HARQ-ACK.

[0064] For an SPS HARQ-ACK corresponding to a certain SPS configuration (SPS-Config), determination of a time domain type corresponding to the SPS HARQ-ACK (hereinafter collectively referred to as the time domain type corresponding to the SPS HARQ-ACK) may be implemented based on at least one of the following five determination methods:

[0065] 1) Time domain type determination method 1: predefined (such as specified in the protocol) or high-level signaling configuration.

[0066] When specified by the protocol, the time domain types corresponding to all SPS HARQ-ACKs of the terminal may be uniformly specified, or the time domain type corresponding to the SPS HARQ-ACK for a certain physical layer priority (PHY priority) may be specified.

[0067] When configured by high-layer signaling, a new radio resource control (RRC) parameter can be introduced in SPS-Config to explicitly configure the time domain type corresponding to the SPS HARQ-ACK corresponding to this SPS-Config, or the time domain type corresponding to all SPS HARQ-ACKs of the terminal can be uniformly configured, or the time domain type corresponding to the SPS HARQ-ACK for a certain physical layer priority (PHY priority) can be configured.

[0068] 2) Time domain type determination method 2: Activation DCI indication, where the activation DCI is used to activate the transmission of the SPS PDSCH corresponding to the SPS HARQ-ACK.

[0069] The activation DCI may also be a reactivation DCI. In the embodiments of this specification, activation DCI and reactivation DCI are collectively referred to as activation DCI.

[0070] In this embodiment, for example, a new indication field is introduced or the existing indication field is reinterpreted in the DCI format (DCI format) for activating this SPS-Config, such as DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 4_1, and DCI format 4_2, to indicate the time domain type corresponding to the SPS HARQ-ACK corresponding to the corresponding SPS PDSCH transmission of this SPS-Config after this activation or reactivation and before release.

[0071] 3) Time domain type determination method 3: the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK.

[0072] The initial PUCCH time domain unit of SPS HARQ-ACK can be the initial PUCCH time slot (Initial PUCCH slot) of SPS HARQ-ACK. The Initial PUCCH slot here can be understood as a certain SPS PDSCH (assuming it is located in Slot n) transmission based on HARQ-ACK reporting Timing (such as k indicated by activation / reactivation DCI, or k configured by high-level signaling) expected to report its corresponding SPS HARQ-ACK PUCCH slot (when the uplink and downlink SCS are equal, and the PUCCH slot adopts the Slot granularity, it is Slot n+k); it can also be understood as the Initial PUCCH slot of this SPS HARQ-ACK. The PUCCH slot here can be understood as a PUCCH time domain unit determined based on the PUCCH configuration parameters (such as subslotLengthForPUCCH-r16), which can be a Slot or Sub-slot.

[0073] 4) Time domain type determination method 4: the time domain type corresponding to the PUCCH resource used to transmit the SPS HARQ-ACK.

[0074] This embodiment mainly considers the situation where the terminal does not need to determine the SPS HARQ-ACK PUCCH resource (resource) (including the starting symbol of this PUCCH resource, the number of symbols, etc.) according to the time domain type (such as Symbol type). For example, in the PUCCH resource sets applied by the SBFD symbol and the non-SBFD symbol respectively, the time domain resource configuration of each corresponding PUCCH resource is common or the same. Optionally, the PUCCH resource sets applied by both are uniformly configured, and only a frequency domain offset (Offset) is introduced in the frequency domain, which is applied to each PUCCH resource in this PUCCH resource set respectively. Furthermore, for SBFD symbol and non-SBFD symbol, the HARQ-ACK PUCCH resource of a single SPS PDSCH (PUCCH resource corresponding to n1PUCCH-AN), or the HARQ-ACK joint feedback PUCCH resource of multiple SPS PDSCHs (each corresponding PUCCH resource in the SPS-PUCCH-AN-List), the corresponding time domain resource configuration is the same.

[0075] 5) Time domain type determination method 5: the time domain type corresponding to the initial PUCCH time domain unit of the target SPS HARQ-ACK; or the time domain type corresponding to the PUCCH resource used by the target SPS HARQ-ACK; wherein the target SPS HARQ-ACK is the SPS HARQ-ACK corresponding to the first SPS PDSCH after activation or reactivation.

[0076] This embodiment may use the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK corresponding to the first SPS PDSCH transmission after activation or reactivation, or the time domain type corresponding to the PUCCH resource used for the SPS HARQ-ACK feedback.

[0077] Time domain type determination method 5 can be understood as a variant of time domain type determination method 3 or time domain type determination method 4. The difference is that time domain type determination method 5 only considers the corresponding attributes of the SPS HARQ-ACK corresponding to the first SPS PDSCH transmission after activation or reactivation to determine the time domain type of the SPS HARQ-ACK corresponding to each SPS PDSCH transmission after this activation or reactivation.

[0078] For the above five determination methods of time domain types, the method also includes the following steps: the terminal determines the determination method based on at least one of the following: 1) the physical layer priority corresponding to the SPS HARQ-ACK; 2) the DCI format of the activated DCI, and the activated DCI is used to activate the transmission of the SPS PDSCH corresponding to the SPS HARQ-ACK.

[0079] This embodiment can distinguish the physical layer priority (PHY priority) of SPS HARQ-ACK, or the DCI format of the activation or reactivation DCI corresponding to the SPS HARQ-ACK, etc., and adopt different time domain type determination methods, which can be specified by the protocol or configured by high-level signaling. For example, for SPS PDSCH transmission activated or reactivated by fallback DCI format (Fallback DCI format, for example, DCI format 1_0), the time domain type of the corresponding SPS HARQ-ACK can be determined by the above-mentioned time domain type determination method 1; for SPS PDSCH transmission activated / reactivated by non-fallback DCI format (Non-fallback DCI format, for example, DCI format 1_1 or DCI format 1_2), the time domain type of the corresponding SPS HARQ-ACK can be determined by the above-mentioned time domain type determination method 2.

[0080] The following will introduce the circumstances under which delayed transmission of SPS HARQ-ACK is triggered, or in other words, the triggering decision of delayed transmission of SPS HARQ-ACK.

[0081] In the initial PUCCH time domain unit of the SPS HARQ-ACK corresponding to one or more SPS-Configs (assuming that the SPS HARQ-ACK delay operation is configured for each SPS-Config in the one or more SPS-Configs), it is assumed that each SPS-Config in the one or more SPS-Configs has at least one corresponding SPS PDSCH transmission based on its HARQ-ACK reporting Timing. It is expected to report its corresponding HARQ-ACK within this initial PUCCH time domain unit, and the time domain type of these expected reported SPS HARQ-ACKs is the same, and the PHY priority is also the same (if configured); it can be understood that this SPS HARQ-ACK may include one or more HARQ-ACKs corresponding to SPS PDSCH transmissions. When multiple SPS PDSCH transmissions are involved, the HARQ-ACKs corresponding to these multiple SPS PDSCH transmissions correspond to the same initial PUCCH time domain unit, and the time domain type of the HARQ-ACKs corresponding to these multiple SPS PDSCH transmissions is the same, and the PHY priority is also the same (if configured), the triggering of the SPS The delayed transmission of the HARQ-ACK includes triggering the delayed transmission of the SPS HARQ-ACK when at least one of the following delay triggering criteria is met:

[0082] 1) Delay triggering criterion 1: The time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK is different from the time domain type corresponding to the SPS HARQ-ACK.

[0083] For example, the time domain type (such as Symbol type, assuming Symbol type 1) corresponding to the initial PUCCH time domain unit (such as Initial PUCCH slot) is different from the time domain type (Symbol type, assuming Symbol type 2) corresponding to this SPS HARQ-ACK.

[0084] It can be understood that the Initial PUCCH slot can only provide valid PUCCH resources for SPS HARQ-ACK (or other UCI, including P / SP-CSI on PUCCH, SR, DG HARQ-ACK, etc.) corresponding to Symbol type 1. There are no valid PUCCH resources for SPS HARQ-ACK corresponding to Symbol type 2 in the Initial PUCCH slot (or, the PUCCH parameters corresponding to Symbol type 2 are not available / invalid in the Initial PUCCH slot).

[0085] 2) Delay triggering criterion 2: The time domain type corresponding to any sub-time domain unit within the initial PUCCH time domain unit of the SPS HARQ-ACK is different from the time domain type corresponding to the SPS HARQ-ACK.

[0086] For example, the time domain type (Symbol type) corresponding to any sub-time domain unit (such as Symbol) included in the initial PUCCH time domain unit (such as Initial PUCCH slot) is different from the time domain type (Symbol type) corresponding to the SPS HARQ-ACK.

[0087] 3) Delay trigger criterion 3: The PUCCH resource determined based on the UCI multiplexing operation within the terminal and one of the following two is judged to be invalid: the time domain type corresponding to the SPS HARQ-ACK, and the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK.

[0088] For example, the Symbol type based on the SPS HARQ-ACK or the Symbol type corresponding to the Initial PUCCH slot, and the PUCCH resource determined by the intra-UE UCI multiplexing operation are judged to be invalid.

[0089] In this embodiment, the time domain type corresponding to the SPS HARQ-ACK and the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK are mainly used by the terminal to use the PUCCH parameters corresponding to this time domain type to determine PUCCH-Config, PUCCH-Resource and PUCCH transmission settings, etc.

[0090] The intra-UE UCI multiplexing operation (intra-UE UCI multiplexing) may be the Rel-15 / 16 intra-UE UCI multiplexing related rules and operations. Generally, it may be assumed that the time domain types corresponding to the various UCIs input into the intra-UE UCI multiplexing are the same. Optionally, the time domain types corresponding to the various UCIs input into the intra-UE UCI multiplexing may be different. In this case, the multiplexed PUCCH resource may be determined based on the PUCCH resource corresponding to each UCI and predefined rules (for example, rules specified in the Rel-16 / 17 protocol) (the time domain type corresponding to the multiplexed UCI may be understood as the time domain type corresponding to the multiplexed PUCCH resource).

[0091] In this embodiment, the determined PUCCH resource may be: an SPS HARQ-ACK PUCCH resource, for example, a PUCCH resource determined based on the higher-layer parameter SPS-PUCCH-AN-List-r16 or n1PUCCH-AN and used only for carrying SPS HARQ-ACK, or other PUCCH resources that are not SPS HARQ-ACK PUCCH resources determined for performing intra-UE UCI multiplexing operations. The UE does not determine whether delay trigger criterion 3 is met based on whether the PUCCH resource is invalid before or during intra-UE UCI multiplexing.

[0092] For delay triggering criterion 1 or delay triggering criterion 2, the time domain type actually applied for the delay triggering decision is the time domain type of SPS HARQ-ACK; for delay triggering criterion 3, the time domain actually applied for the delay triggering decision is the time domain type of this SPS HARQ-ACK or the time domain type corresponding to the initial PUCCH time domain unit, that is, the time domain type based on which the terminal is based.

[0093] Optionally, the delay triggering criterion 3 further includes: the determined PUCCH resource is an SPS HARQ-ACK PUCCH resource. In this embodiment, the terminal determines that the delay triggering criterion 3 is met only when the determined PUCCH resource is only an SPS HARQ-ACK PUCCH resource and is determined to be invalid.

[0094] Optionally, in the delay trigger criterion 3, the PUCCH resource is judged to be invalid when the PUCCH resource meets at least one of the following conditions:

[0095] 1) At least one sub-time-domain unit of the PUCCH resource overlaps with a semi-static downlink sub-time-domain unit, a synchronization signal and physical broadcast channel block (SSB) sub-time-domain unit, or a control resource set (CORESET) #0 sub-time-domain unit in the time domain. For example, at least one symbol occupied by the PUCCH resource overlaps with a semi-static DL symbol, an SSB symbol, or a CORESET #0 symbol in the time domain.

[0096] 2) At least one sub-time domain unit of the PUCCH resource is indicated by dynamic signaling as being used for downlink transmission or being unavailable for uplink transmission. For example, at least one symbol occupied by the PUCCH resource is indicated by DCI (e.g., DCI format 1_0 / 1_1 / 1_2, or DCI format 2_0), a Media Access Control Element (MAC CE), or other dynamic signaling as being used for downlink transmission or being unavailable for uplink transmission.

[0097] Optionally, for Duplex mode 1, for SBFD symbols determined based on semi-static / dynamic signaling or predefined rules to be used only for downlink transmission (eg, downlink reception in a DL subband), the terminal regards them as symbols unusable for uplink transmission.

[0098] 3) The time domain type corresponding to at least one sub-time domain unit of the PUCCH resource is different from the time domain type based on the terminal. For example, the symbol type corresponding to at least one symbol occupied by the PUCCH resource is different from the symbol type based on the terminal.

[0099] 4) At least one frequency domain unit occupied by the PUCCH resource belongs to a guard interval or a downlink subband. The frequency domain unit may be a resource element (RE), for example, at least one RE occupied by the PUCCH resource belongs to a guard interval (Guardband) or a downlink subband (DL subband).

[0100] The methods provided in each of the above embodiments further include the following step: the terminal determines the time domain type corresponding to the PUCCH time domain unit based on one of the following:

[0101] 1) When the time domain types corresponding to the sub-time domain units within the PUCCH time domain unit are all the same, the same time domain type is used as the time domain type corresponding to the PUCCH time domain unit;

[0102] 2) When the time domain types corresponding to the sub-time domain units within the PUCCH time domain unit are different, one of the following shall be used as the time domain type corresponding to the PUCCH time domain unit: the time domain type corresponding to the sub-time domain unit with the largest number of sub-time domain units within the PUCCH time domain unit. In this example, the sub-time domain units can be grouped according to different time domain types; the time domain type corresponding to the sub-time domain unit at a predefined position within the PUCCH time domain unit; the default time domain type.

[0103] The PUCCH time domain unit includes the initial PUCCH time domain unit or a time domain unit other than the initial PUCCH time domain unit.

[0104] In this embodiment, based on the semi-static SBFD configuration or the dynamic SBFD indication, for a certain PUCCH time domain unit (such as a PUCCH slot), the corresponding time domain type (such as the symbol type) can be determined based on the following situations:

[0105] Case 1: This PUCCH slot involves only a single symbol type.

[0106] All symbols included in this PUCCH slot correspond to the same symbol type. In this case, this single symbol type is directly used as the symbol type corresponding to this PUCCH slot.

[0107] Case 2: This PUCCH slot involves more than one symbol type.

[0108] At this time, the Symbol type corresponding to this PUCCH slot can be determined based on any of the following:

[0109] a: Use the symbol type that corresponds to a larger number of symbols in this PUCCH slot.

[0110] When the number of symbols corresponding to different symbol types within a PUCCH slot is equal, a default symbol type, such as a non-SBFD symbol, may be used. The default symbol type may be specified by the protocol or configured by higher-layer signaling. If specified by the protocol, a symbol type with more uplink available resources or better coverage performance may be used.

[0111] b: Use the Symbol type corresponding to the Symbol in the predefined position within this PUCCH slot.

[0112] For example, use the Symbol type corresponding to the first or last Symbol in this PUCCH slot.

[0113] c: Use the default Symbol type directly.

[0114] For the default Symbol type, see the corresponding description above.

[0115] The following describes how to determine the target PUCCH time domain unit (eg, Target PUCCH slot) of the delayed SPS HARQ-ACK after the delayed transmission of the SPS HARQ-ACK is triggered.

[0116] After the terminal determines that a delay has been triggered for the SPS HARQ-ACK, the SPS HARQ-ACK may be referred to as a delayed SPS HARQ-ACK (Deferred SPS HARQ-ACK), which may include one or more HARQ-ACK bits.

[0117] When a certain PUCCH time domain unit satisfies at least one of the following determination criteria, the terminal determines this PUCCH time domain unit as the target PUCCH time domain unit corresponding to the delayed SPS HARQ-ACK and stops the delay process of the delayed SPS HARQ-ACK.

[0118] Target PUCCH time domain unit determination criterion 1: The time domain type corresponding to the target PUCCH time domain unit is the same as the time domain type corresponding to the delayed SPS HARQ-ACK.

[0119] For example, when the Symbol type (or time domain type) corresponding to the PUCCH time domain unit (eg, PUCCH slot) is the same as the Symbol type corresponding to the Deferred SPS HARQ-ACK, it is determined to meet the target PUCCH time domain unit determination criterion 1.

[0120] Target PUCCH time domain unit determination criterion 2: the time domain type corresponding to at least one sub-time domain unit within the target PUCCH time domain unit is the same as the time domain type corresponding to the delayed SPS HARQ-ACK;

[0121] For example, when the Symbol type (or time domain type) corresponding to at least one Symbol included in this PUCCH time domain unit is the same as the Symbol type corresponding to the Deferred SPS HARQ-ACK, it is determined that the target PUCCH time domain unit determination criterion 2 is met.

[0122] Target PUCCH time domain unit determination criterion 3: The PUCCH resource determined based on the intra-terminal UCI multiplexing operation and one of the following two is judged to be valid: the time domain type corresponding to the delayed SPS HARQ-ACK, and the time domain type corresponding to the target PUCCH time domain unit.

[0123] For example, when the terminal is judged to be valid based on the Symbol type corresponding to the Deferred SPS HARQ-ACK or the Symbol type (or time domain type) corresponding to this PUCCH time domain unit, and the PUCCH resource determined by the intra-UE UCI multiplexing operation, it is judged to meet the target PUCCH time domain unit determination criterion 3.

[0124] In this embodiment, the time domain type corresponding to the delayed SPS HARQ-ACK, the time domain type corresponding to the target PUCCH time domain unit, or the time domain type corresponding to a PUCCH time domain unit used to determine whether it is the target PUCCH time domain unit, is mainly used by the terminal to use the PUCCH parameters corresponding to this time domain type (or Symbol type) to determine PUCCH-Config, PUCCH-Resource and PUCCH transmission settings, etc.

[0125] When the determined PUCCH resource is not judged to be invalid based on the foregoing description, it can be considered valid.

[0126] Optionally, when the determined PUCCH resource is an SPS HARQ-ACK PUCCH resource and is judged to be valid, or is not an SPS HARQ-ACK PUCCH resource, the terminal determines that target PUCCH time domain unit determination criterion 3 is met.

[0127] For the target PUCCH time domain unit determination criterion 1 or the target PUCCH time domain unit determination criterion 2, the target PUCCH time domain unit determines that the time domain type actually applied is the time domain type corresponding to the delayed SPS HARQ-ACK; for the target PUCCH time domain unit determination criterion 3, the target PUCCH time domain unit determines that the time domain type actually applied is the time domain type corresponding to the delayed SPS HARQ-ACK, or the time domain type corresponding to this PUCCH time domain unit, that is, the time domain type based on the terminal.

[0128] In each of the above embodiments, after triggering the delayed transmission of the SPS HARQ-ACK, the method further includes: when the initial PUCCH time domain unit of the SPS HARQ-ACK meets a predefined condition, the terminal determines whether the initial PUCCH time domain unit can be used as the target PUCCH time domain unit based on a first time domain type; wherein the first time domain type is a time domain type other than the time domain type to which the delayed triggering criterion of the SPS HARQ-ACK is applied.

[0129] The predefined conditions include one of the following: 1) the time domain type corresponding to the initial PUCCH time domain unit is different from the time domain type applied to the delayed triggering criterion of the SPS HARQ-ACK; 2) the time domain type corresponding to at least one sub-time domain unit within the initial PUCCH time domain unit is the first time domain type.

[0130] In this embodiment, after triggering the delayed transmission of the SPS HARQ-ACK, if the Initial PUCCH slot meets the predefined conditions, the UE determines within the Initial PUCCH slot whether the Initial PUCCH slot can be determined as a Target PUCCH slot, that is, whether it can be used as an Intra-PUCCH slot deferral, based on other Symbol types other than the Symbol type actually applied for the Deferral trigger decision.

[0131] The predefined conditions may include at least one of the following: 1) The symbol type corresponding to the Initial PUCCH slot is different from the symbol type actually used for the deferral triggering decision. In this case, the symbol type corresponding to the Initial PUCCH slot may be used as the "other symbol type" mentioned above. 2) At least one symbol contained in the Initial PUCCH slot corresponds to a symbol type other than the symbol type actually used for the deferral triggering decision. When there are multiple "other symbol types" here, the Intra-PUCCH slot deferral decision may be made based on the "other symbol type" with the larger number of corresponding symbols.

[0132] In each of the above embodiments, after the terminal performs the first operation, the method further includes: terminating the delayed transmission of the SPS HARQ-ACK when one of the following conditions is met: 1) the time interval between the delayed SPS HARQ-ACK and the SPS PDSCH exceeds the maximum delay value; 2) the network side device triggers type 3 codebook transmission.

[0133] In this embodiment, terminating the delayed transmission of the SPS HARQ-ACK may be understood as: the delayed SPS HARQ-ACK is discarded, and the delay process is no longer performed.

[0134] The suspension of the delayed transmission process includes at least one of the following:

[0135] 1) When the time interval between the Deferred SPS HARQ-ACK and the corresponding SPS PDSCH exceeds the pre-configured maximum Deferral value, the terminal terminates the corresponding Deferral process in the first / earliest PUCCH slot that exceeds the pre-configured maximum Deferral value.

[0136] Optionally, when the time interval between the Deferred SPS HARQ-ACK and the corresponding SPS PDSCH has reached the preconfigured maximum Deferral value and the UE does not determine the current PUCCH slot as the Target PUCCH slot of the Deferred SPS HARQ-ACK, the UE terminates the corresponding Deferral process in this PUCCH slot.

[0137] The pre-configured maximum deferral value here can be configured for each SPS-Config separately. Optionally, the pre-configured maximum deferral value corresponding to different Symbol types can be configured separately in each SPS-Config.

[0138] 2) When the (enhanced) Type-3 codebook is triggered, the terminal terminates the corresponding Deferral process in the PUCCH slot where the triggered (enhanced) Type-3 codebook is transmitted.

[0139] The (enhanced) Type-3 codebook here can be understood as Type-3 codebook and / or enhanced Type-3 codebook, which can be triggered by a network-side device.

[0140] For HARQ-ACK retransmission, the terminal uses the PUCCH slot where the triggered HARQ-ACK retransmission is located as the Target PUCCH slot of the Deferred SPS HARQ-ACK, concatenates the Deferred SPS HARQ-ACK at the end of the triggered retransmission HARQ-ACK codebook and reports it to the network side. At this time, the Deferral process is stopped normally.

[0141] Optionally, in each of the above embodiments, the time domain type applied by the SPS HARQ-ACK during the delay process remains unchanged, as specifically seen in Example 1 below; or, the time domain type applied by the SPS HARQ-ACK during the delay process is adjusted based on a predefined rule, as specifically seen in Example 2 below.

[0142] To illustrate in detail the SPS HARQ-ACK transmission method provided in the embodiments of the present application, two specific embodiments will be described below.

[0143] The following two embodiments are described by taking the example that the time domain type is the symbol type, the time domain unit is a time slot, and the sub-time domain unit is a symbol.

[0144] Example 1

[0145] In this embodiment, the Symbol type actually used by the SPS HARQ-ACK during the deferral process remains unchanged.

[0146] In this embodiment, after the Symbol type corresponding to the SPS HARQ-ACK is determined, in the Deferral triggering decision in the Initial PUCCH slot and in the possible Deferral process, the actually applied Symbol type remains the Symbol type corresponding to the SPS HARQ-ACK and does not change.

[0147] Assume that the SPS-Config cycle is one slot, and k = 3. A TDD pattern cycle consists of five slots, using the DDDUU configuration. The second and third D slots are configured as SBFD slots. Figure 3 shows two TDD pattern cycles.

[0148] The following describes how to determine the Symbol type corresponding to the SPS HARQ-ACK (before triggering Deferral).

[0149] The Symbol type corresponding to the SPS HARQ-ACK can be determined by any of the aforementioned time domain type (Symbol type) determination methods 1, 2, and 3. In FIG3 , the Symbol type corresponding to the HARQ-ACK of the SPS PDSCH 3 is a non-SBFD symbol.

[0150] The following describes the Deferral triggering decision for SPS HARQ-ACK in the Initial PUCCH slot.

[0151] The deferral triggering decision for SPS HARQ-ACK in the Initial PUCCH slot can be any of the following combinations:

[0152] Deferral trigger criterion combination 1: Deferral trigger criterion 1 + Deferral trigger criterion 3 (based on the Symbol type corresponding to SPS HARQ-ACK).

[0153] Deferral trigger criterion combination 2: Deferral trigger criterion 2 + Deferral trigger criterion 3 (based on the Symbol type corresponding to SPS HARQ-ACK).

[0154] Deferral trigger criterion combination 3: Deferral trigger criterion 3 (based on the Symbol type corresponding to SPS HARQ-ACK).

[0155] The above “delay triggering criterion 3 (based on the Symbol type corresponding to SPS HARQ-ACK)” can be understood as: adopting the delay triggering criterion 3, and the terminal is based on the PUCCH parameters corresponding to the Symbol type corresponding to SPS HARQ-ACK.

[0156] When the Deferral triggering decision of the SPS HARQ-ACK in the Initial PUCCH slot adopts a certain combination, it can be understood that: the terminal decides to trigger the Deferral only when all the delay triggering criteria in this combination are met at the same time.

[0157] In Figure 3, when the HARQ-ACK of SPS PDSCH 3 makes a delayed trigger decision based on delay trigger criterion 3 (based on the Symbol type corresponding to SPS HARQ-ACK), the determined PUCCH resource is only the SPS HARQ-ACK PUCCH resource and is judged to be invalid (any Symbol occupied by the PUCCH resource is a Semi-static DL symbol), thereby triggering the Deferral process.

[0158] The following describes the determination of the Target PUCCH slot for Deferred SPS HARQ-ACK (after Deferral is triggered).

[0159] After the Deferral procedure is triggered, when determining whether a potential target PUCCH slot is a target PUCCH slot, any of the following combinations may be used:

[0160] Target PUCCH slot determination criterion combination 1: target PUCCH time domain unit determination criterion 1 + target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to Deferred SPS HARQ-ACK).

[0161] Target PUCCH slot determination criterion combination 2: target PUCCH time domain unit determination criterion 2 + target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to Deferred SPS HARQ-ACK).

[0162] Target PUCCH slot determination criterion combination 3: Target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to Deferred SPS HARQ-ACK).

[0163] The above-mentioned “target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to Deferred SPS HARQ-ACK)” can be understood as: adopting the target PUCCH time domain unit determination criterion 3, and the terminal is based on the PUCCH parameters corresponding to the Symbol type corresponding to Deferred SPS HARQ-ACK.

[0164] When determining whether a certain Potential target PUCCH slot is a Target PUCCH slot using a certain combination, it can be understood that the terminal determines that the Potential target PUCCH slot is a Target PUCCH slot only when the determination criteria of each target PUCCH time domain unit in the combination are simultaneously met.

[0165] Generally, a correspondence must be maintained between the deferral triggering decision and the criteria combination used to determine the Target PUCCH slot to ensure consistency in UE behavior within the Initial PUCCH slot and the Target PUCCH slot. It is understood that the Deferral triggering criteria combinations 1 / 2 / 3 correspond one-to-one with the Target PUCCH slot determination criteria combinations 1 / 2 / 3.

[0166] Assume that the HARQ-ACK of SPS PDSCH 3 in Figure 3 triggers the Deferral process in Slot 5 based on Deferral triggering criterion combination 1. In Slot 6 or Slot 7, when the Target PUCCH slot determination is made based on Target PUCCH slot determination criterion combination 1, Slot 6 or Slot 7 corresponds to the SBFD symbol, and thus does not meet the target PUCCH time domain unit determination criterion 1. Slot 8 meets both target PUCCH time domain unit determination criterion 1 and target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to the Deferred SPS HARQ-ACK) and is thus determined to be the Target PUCCH slot. The UE reports the Deferred SPS HARQ-ACK in Slot 8 and ends the Deferral process normally.

[0167] Example 2

[0168] In this embodiment, the SPS HARQ-ACK adjusts its actually applied Symbol type based on predefined rules during the Deferral process.

[0169] In this embodiment, in the Deferral triggering decision in the Initial PUCCH slot and in the possible Deferral process, the actually applied Symbol type adopts the Symbol type corresponding to the PUCCH slot, which may be different from the Symbol type corresponding to the SPS HARQ-ACK.

[0170] Assume that the SPS-Config cycle is one slot, and k = 3. A TDD pattern cycle consists of five slots, using the DDDUU configuration. The second and third D slots are configured as SBFD slots. Figure 3 shows two TDD pattern cycles.

[0171] The following describes how to determine the Symbol type corresponding to the SPS HARQ-ACK (before triggering Deferral).

[0172] The Symbol type corresponding to the SPS HARQ-ACK can be determined using any of the time domain type determination methods 1, 2, and 3. In FIG4 , the Symbol type corresponding to the HARQ-ACK of the SPS PDSCH 3 is a non-SBFD symbol.

[0173] It should be noted that the Symbol type corresponding to SPS HARQ-ACK is not actually used in subsequent operations.

[0174] The following describes the Deferral triggering decision for SPS HARQ-ACK in the Initial PUCCH slot.

[0175] The following combinations can be used for the Deferral triggering decision of SPS HARQ-ACK in the Initial PUCCH slot:

[0176] Deferral trigger criterion combination 4: Deferral trigger criterion 3 (based on the Symbol type corresponding to the Initial PUCCH slot).

[0177] The above “delay triggering criterion 3 (based on the Symbol type corresponding to the Initial PUCCH slot)” can be understood as: adopting the delay triggering criterion 3, and the terminal is based on the PUCCH parameters corresponding to the Symbol type corresponding to the Initial PUCCH slot.

[0178] In Figure 4, when the HARQ-ACK of SPS PDSCH 3 makes a Deferral trigger decision based on delay trigger criterion 3 (based on the Symbol type corresponding to the Initial PUCCH slot), the determined PUCCH resource is only the SPS HARQ-ACK PUCCH resource and is judged to be invalid (any Symbol occupied by the PUCCH resource is a Semi-static DL symbol), thereby triggering the Deferral process.

[0179] The following describes the determination of the Target PUCCH slot for Deferred SPS HARQ-ACK (after Deferral is triggered).

[0180] After the Deferral process is triggered, the following combinations can be used to determine whether a Potential target PUCCH slot is a Target PUCCH slot:

[0181] Target PUCCH slot determination criterion combination 4: target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to the PUCCH slot).

[0182] The above “target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to the PUCCH slot)” can be understood as: adopting the target PUCCH time domain unit determination criterion 3, and the terminal is based on the PUCCH parameters corresponding to the Symbol type corresponding to the PUCCH slot.

[0183] Assume that the HARQ-ACK of SPS PDSCH 3 in Figure 4 is based on Deferral triggering criterion combination 4, triggering the Deferral process in Slot 5. In Slot 6, when the Target PUCCH slot is determined based on Target PUCCH slot determination criterion combination 4, the UE performs intra-UE UCI multiplexing based on the PUCCH parameters corresponding to the SBFD symbol. The determined PUCCH resource is the SPS HARQ-ACK PUCCH resource and is judged to be valid, thereby meeting the target PUCCH time domain unit determination criterion 3 (based on the Symbol type corresponding to the PUCCH slot). Therefore, Slot 6 is judged as the Target PUCCH slot. The UE reports Deferred SPS HARQ-ACK in Slot 6 and ends the Deferral process normally.

[0184] The above describes in detail the SPS HARQ-ACK transmission method according to an embodiment of the present application in conjunction with Figures 2 to 4. The following describes in detail the SPS HARQ-ACK transmission method according to another embodiment of the present application in conjunction with Figure 5. It can be understood that the interaction between the network-side device and the terminal described from the perspective of the network-side device is the same as or corresponds to the description of the terminal side in the method shown in Figure 2. To avoid repetition, the relevant description is appropriately omitted.

[0185] FIG5 is a flow chart of an implementation method for transmitting SPS HARQ-ACK according to an embodiment of the present application, which can be applied to a network-side device. As shown in FIG5 , the method 500 includes the following steps.

[0186] S502: The network-side device performs a first operation, where the first operation is used to perform delayed transmission of SPS HARQ-ACK on a carrier or cell configured to adopt SBFD, and the first operation includes at least one of the following: determining a time domain type corresponding to the SPS HARQ-ACK; determining that the SPS HARQ-ACK is delayed in transmission; and determining a target PUCCH time domain unit, where the target PUCCH time domain unit is used to transmit the delayed SPS HARQ-ACK.

By performing the first operation, delayed transmission of the SPS HARQ-ACK can be performed on a carrier or cell configured with SBFD, which is beneficial to improving the probability of successful transmission of the SPS HARQ-ACK, thereby improving the transmission performance of the SPS PDSCH.

[0188] Optionally, as an embodiment, determining the time domain type corresponding to the SPS HARQ-ACK includes: determining the time domain type corresponding to the SPS HARQ-ACK based on at least one of the following determination methods: predefined or high-layer signaling configuration; activation DCI indication, the activation DCI is used to activate the transmission of the SPS PDSCH corresponding to the SPS HARQ-ACK; the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK; the time domain type corresponding to the PUCCH resources used to transmit the SPS HARQ-ACK; the time domain type corresponding to the initial PUCCH time domain unit of the target SPS HARQ-ACK; the time domain type corresponding to the PUCCH resources used by the target SPS HARQ-ACK; wherein the target SPS HARQ-ACK is the SPS HARQ-ACK corresponding to the first SPS PDSCH after activation or reactivation.

[0189] Optionally, as an embodiment, determining that the SPS HARQ-ACK is delayed in transmission includes: determining that the SPS HARQ-ACK is delayed in transmission when at least one of the following delay trigger criteria is met: the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK is different from the time domain type corresponding to the SPS HARQ-ACK; the time domain type corresponding to any sub-time domain unit within the initial PUCCH time domain unit of the SPS HARQ-ACK is different from the time domain type corresponding to the SPS HARQ-ACK; the PUCCH resources determined based on the UCI multiplexing operation within the terminal and one of the following two are judged to be invalid: the time domain type corresponding to the SPS HARQ-ACK, and the time domain type corresponding to the initial PUCCH time domain unit of the SPS HARQ-ACK.

[0190] Optionally, as an embodiment, the target PUCCH time domain unit satisfies one of the following: the time domain type corresponding to the target PUCCH time domain unit is the same as the time domain type corresponding to the delayed SPS HARQ-ACK; the time domain type corresponding to at least one sub-time domain unit within the target PUCCH time domain unit is the same as the time domain type corresponding to the delayed SPS HARQ-ACK; the PUCCH resources determined based on the UCI multiplexing operation within the terminal and one of the following two are judged to be valid: the time domain type corresponding to the delayed SPS HARQ-ACK, and the time domain type corresponding to the target PUCCH time domain unit.

[0191] Optionally, as an embodiment, the method further includes: determining that the delayed transmission of the SPS HARQ-ACK is terminated when one of the following conditions is met: the time interval between the delayed SPS HARQ-ACK and the SPS PDSCH exceeds the maximum delay value; the network side device triggers type 3 codebook transmission.

[0192] The SPS HARQ-ACK transmission method provided in the embodiment of the present application may be performed by an SPS HARQ-ACK transmission device. In the embodiment of the present application, the SPS HARQ-ACK transmission method performed by the SPS HARQ-ACK transmission device is taken as an example to illustrate the SPS HARQ-ACK transmission device provided in the embodiment of the present application.

[0193] FIG6 is a schematic diagram of the structure of an apparatus for transmitting SPS HARQ-ACK according to an embodiment of the present application, which may correspond to a terminal in other embodiments. As shown in FIG6 , apparatus 600 includes the following modules.

[0194] The first execution module 602 is used to perform a first operation, where the first operation is used to perform delayed transmission of SPS HARQ-ACK on a carrier or cell configured to adopt SBFD, and the first operation includes at least one of the following: determining the time domain type corresponding to the SPS HARQ-ACK; triggering the delayed transmission of the SPS HARQ-ACK; determining a target PUCCH time domain unit, where the target PUCCH time domain unit is used to transmit the delayed SPS HARQ-ACK.

[0195] Optionally, the device 600 further includes a transmission module, etc.

By performing the first operation, delayed transmission of the SPS HARQ-ACK can be performed on a carrier or cell configured with SBFD, which is beneficial to improving the probability of successful transmission of the SPS HARQ-ACK, thereby improving the transmission performance of the SPS PDSCH.
