Description

Transmission method, apparatus, terminal and network device of HARQ-ACK

[0001] The present disclosure claims priority from a Chinese patent application No. 202411340588.5 entitled "Transmission method, apparatus, terminal and network device of HARQ-ACK" filed on September 25, 2024 with the China Patent Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, in particular to a transmission method, apparatus, terminal and network device of HARQ-ACK. BACKGROUND

[0003] In related technologies, full duplex is supported in subbands that do not overlap, that is, the base station can simultaneously transmit and receive through different subbands in a frequency band, carrier or bandwidth part (BandWidth Part, BWP), and the subbands used for transmission and reception do not overlap. A subband full duplex (SubBand Full Duplex, SBFD) symbol is a symbol that simultaneously contains a subband used for uplink transmission and a subband used for downlink transmission.

[0004] For periodic or semi-persistent channels configured for repeated transmission, multi-slot scheduling, etc., the current discussion considers that these channels / signals of the SBFD terminal can be transmitted only in one symbol type or across different symbol types in different time slots. Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) hybrid automatic repeat request-acknowledgement (Hybrid Automatic Repeat request-Acknowledgement, HARQ-ACK) is carried through a semi-persistent physical uplink control channel (Physical Uplink Control Channel, PUCCH), so it is also possible to support transmission only in one symbol type.

[0005] The current SPS HARQ-ACK delay process does not involve two symbol types, so for SPS HARQ-ACK that only supports transmission in one symbol type and supports SPS HARQ-ACK delay, how to implement the transmission of SPS HARQ-ACK is a problem to be solved. SUMMARY

[0006] The embodiment of the present disclosure provides a transmission method, device, terminal and network equipment of HARQ-ACK, so as to ensure the accurate transmission of SPS HARQ-ACK in the case that SPS HARQ-ACK is configured to be delayed and only supports the transmission of SPS HARQ-ACK in one symbol type.

[0095] With reference to the drawings, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present disclosure.

[0096] The terms "first", "second", and the like in the description and claims of the present disclosure are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein, for example, are implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to include only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0097] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects. In the embodiments of the present disclosure, the term "a plurality of" means two or more, and other quantifiers are similar.

[0098] In the embodiments of the present disclosure, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0099] The related concepts mentioned in the present disclosure will be briefly described as follows.

[0100] 5th Generation New Radio (5G NR) supports Time Domain Duplex (TDD) and Frequency Domain Duplex (FDD), which are two duplex communication modes in mobile communication technology. TDD mode transmits and receives at different times in the same frequency channel, i.e., carrier, and distinguishes uplink and downlink transmission resources by time; FDD mode transmits and receives at the same time in different frequency channels, and distinguishes uplink and downlink transmission resources by frequency.

[0101] I. SBFD

[0102] Currently, only SBFD subbands can be configured in the downlink symbols or flexible symbols of the TDD-Uplink (UL)-Downlink (DL)-ConfigCommon configuration in the time domain. For a full-duplex subband system, the currently considered SBFD subband configurations include the following two subband configuration cases:

[0103] SBFD subband configuration 1 uses the {DUD} mode, i.e., one SBFD slot contains one uplink subband at the center of the carrier bandwidth and two downlink subbands on both sides of the carrier bandwidth.

[0104] SBFD subband configuration 2 uses the {DU} mode, i.e., one SBFD slot contains one uplink subband on one side of the carrier bandwidth and one downlink subband on the other side of the carrier bandwidth.

[0105] The terminal in the SBFD system is a half-duplex terminal, which can be an SBFD-enabled terminal or a non-SBFD-enabled terminal. The SBFD-enabled terminal is a terminal that knows the SBFD subband configuration, or a terminal that knows the access base station to perform the SBFD operation, or a terminal of a later version, hereinafter referred to as an SBFD terminal. For the SBFD terminal, some new terminal behaviors can be defined. The non-SBFD-enabled terminal is an early terminal, or a traditional terminal, or a terminal that does not know the SBFD subband configuration, or a terminal that does not know the access base station to perform the SBFD operation.

[0106] SBFD symbols are orthogonal frequency division multiplexing (OFDM) symbols configured with SBFD subbands, and non-SBFD symbols are OFDM symbols without SBFD subbands.

[0107] Currently in the research, it is considered that the SBFD terminal can be configured to transmit in only one symbol type, or configured to transmit across different symbol types in different slots, and this configuration can be configured for user equipment (UE) or independently configured for each channel of the UE. The terminal is configured to transmit in only one symbol type, that is, for periodic channels / signals, repeatedly transmitted channels / signals, or multi-slot scheduled channels / signals, etc., only support transmission in SBFD symbols, or only in non-SBFD symbols. The terminal is configured to transmit across different symbol types in different slots, that is, the transmission of periodic channels / signals, repeatedly transmitted channels / signals, or multi-slot scheduled channels / signals in different slots can use different symbol types.

[0108] II. SPS HARQ-ACK delay

[0109] NR supports SPS HARQ-ACK delay in Rel-17 Ultra-reliable and Low Latency Communications (URLLC), when the initial slot / sub-slot of SPS HARQ-ACK is unavailable, the terminal determines the availability of each subsequent slot / sub-slot in time order until the target slot is determined.

[0110] In the initial slot of SPS HARQ-ACK, the Uplink Control Information (UCI) multiplexing process is performed first, and if SPS HARQ-ACK and other channels are multiplexed, it cannot be delayed; if the SPS HARQ-ACK after multiplexing is transmitted using the resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, and this resource is invalid, the SPS HARQ-ACK configured with SPS HARQ-ACK delay is delayed, otherwise if this resource is valid, the SPS HARQ-ACK is transmitted in the slot. When the SPS HARQ-ACK resource and the semi-statically configured downlink symbol, Synchronization Signal and PBCH block (SSB), and / or Control Resource Set (CORESET) #0 conflict, this SPS HARQ-ACK resource is an invalid resource.

[0111] When determining whether the next slot / sub-slot is the target slot, the UCI multiplexing process is performed first, and then the next slot / sub-slot that meets the following conditions is determined as the target slot:

[0112] a) if the multiplexed SPS HARQ-ACK is transmitted using the resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN and this resource is valid; or

[0113] b) if the multiplexed SPS HARQ-ACK is transmitted using PUCCH or Physical Uplink Shared Channel (PUSCH) resource other than the resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN.

[0114] If the target slot is found based on the rule, the SPS HARQ-ACK is transmitted in the target slot. If the SPS HARQ-ACK cannot be transmitted in the target slot, the SPS HARQ-ACK no longer continues to be delayed, but is discarded.

[0115] Embodiments of the present disclosure are described below with reference to the accompanying drawings. The HARQ-ACK transmission method, apparatus, terminal and network device provided by the embodiments of the present disclosure can be applied in a wireless communication system. The wireless communication system can be a system using a 5th Generation (5G) mobile communication technology (hereinafter referred to as a 5G system), and those skilled in the art can understand that the 5G NR system is only an example and is not limited.

[0116] In some embodiments, the structure of a network system to which the embodiments of the present disclosure can be applied includes a user terminal and a base station, wherein the user terminal can be a user equipment (UE), for example, a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device, and it should be noted that the specific type of user terminal is not limited in the embodiments of the present disclosure. The base station can be a 5G and later version base station (for example, gNB, 5G NR NB), or a base station in other communication systems, or a node B, and it should be noted that the 5G base station is only an example in the embodiments of the present disclosure, but the specific type of base station is not limited.

[0117] The embodiment of the present disclosure provides a HARQ-ACK transmission method, device, terminal and network device, so as to ensure accurate transmission of SPS HARQ-ACK in the case that SPS HARQ-ACK is configured to be delayed and only supports transmission in one symbol type.

[0118] The method and the device are based on the same application concept, and since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described here.

[0119] As shown in FIG. 1, the embodiment of the present disclosure provides a HARQ-ACK transmission method, which is executed by a terminal and includes the following steps.

[0120] In step S101, if SPS HARQ-ACK is only transmitted in one type of symbol and SPS HARQ-ACK is configured to be delayed, the symbol type of the initial transmission position of the first SPS HARQ-ACK is determined.

[0121] In some embodiments, the symbol type includes one of the following: SBFD symbol, non-SBFD symbol.

[0122] In step S102, according to whether the symbol type of the initial transmission position of the first SPS HARQ-ACK is the symbol type available to the first SPS HARQ-ACK, the transmission mode of the first SPS HARQ-ACK is determined, and the transmission mode includes one of the following: transmission, delayed transmission, and discard.

[0123] In some embodiments, the symbol type available to the first SPS HARQ-ACK can be agreed by protocol or configured by a network device, or determined based on a specific rule; for example, the symbol type available to the first SPS HARQ-ACK is agreed by protocol to be a non-SBFD symbol, or for example, the symbol type available to the first SPS HARQ-ACK is determined based on the symbol type in which the first SPS HARQ-ACK corresponding to the SPS is transmitted for the first time after activation.

[0124] In step S103, according to the transmission mode, the transmission or discard of the first SPS HARQ-ACK is performed.

[0125] In some embodiments, in the case that the transmission mode is transmission or delayed transmission, the terminal will perform the transmission of the first SPS HARQ-ACK at a suitable transmission opportunity, and in the case that the transmission mode is discard, the terminal will discard the first SPS HARQ-ACK and not perform the transmission of the first SPS HARQ-ACK.

[0126] It should be noted that the terminal in the embodiments of the present disclosure is a terminal supporting SBFD capability, which can be referred to as an SBFD terminal.

[0127] It should be noted that in the embodiments of the present disclosure, when SPS HARQ-ACK is transmitted only in one type of symbol and SPS HARQ-ACK is configured to be transmitted with delay, the symbol type of the initial transmission position of the first SPS HARQ-ACK is first determined, and then the transmission mode of the first SPS HARQ-ACK is determined according to whether the symbol type of the initial transmission position of the first SPS HARQ-ACK is the symbol type available to the first SPS HARQ-ACK, and the transmission or discarding of the first SPS HARQ-ACK is performed according to the transmission mode, so as to ensure the accurate transmission of SPS HARQ-ACK and ensure the communication reliability.

[0129] A11, in the case where the symbol type of the initial transmission position of the first SPS HARQ-ACK is the symbol type available to the first SPS HARQ-ACK, the transmission mode of the first SPS HARQ-ACK is determined to be transmission, delayed transmission or discarding;

[0130] In some embodiments, in the case where A11 corresponds, the specific implementation process of determining the transmission mode of the first SPS HARQ-ACK is as follows:

[0131] First, an uplink control information (UCI) multiplexing procedure is performed. If the first SPS HARQ-ACK and other channels are multiplexed (using a PUCCH resource other than a resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN or using a PUSCH resource), the transmission mode of the first SPS HARQ-ACK is determined to be transmission or discard based on whether the multiplexed resource is valid or invalid. If the first SPS HARQ-ACK is transmitted using a resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, and this resource is invalid, the transmission mode of the first SPS HARQ-ACK is determined to be delayed transmission, i.e., the first SPS HARQ-ACK is transmitted in a delayed manner. Otherwise, if this resource is valid, the transmission mode of the first SPS HARQ-ACK is determined to be transmission, i.e., the first SPS HARQ-ACK is transmitted in the slot. It should be noted that when the SPS HARQ-ACK resource and the semi-statically configured downlink symbol, SSB, and / or CORESET#0 conflict, the SPS HARQ-ACK resource is an invalid resource.

[0132] A12, in a case where a symbol type at an initial transmission position of the first SPS HARQ-ACK is an unusable symbol type for the first SPS HARQ-ACK, determining a transmission mode of the first SPS HARQ-ACK to be discard or delayed transmission;

[0133] It should be noted that in this case, it can be understood that as long as the initial transmission position is a symbol of an unusable symbol type, the transmission mode of the first SPS HARQ-ACK is discard or delayed transmission. The transmission mode in this case can be a protocol agreement or preconfigured by a network device.

[0134] A13, in a case where a symbol type at an initial transmission position of the first SPS HARQ-ACK is an unusable symbol type for the first SPS HARQ-ACK, determining a transmission mode of the first SPS HARQ-ACK based on whether the first SPS HARQ-ACK is multiplexed with other channels in a symbol of the unusable symbol type;

[0135] It should be noted that in this case, the transmission mode needs to be determined based on the multiplexing with other channels. In some embodiments, the specific implementation of determining the transmission mode of the first SPS HARQ-ACK based on whether the first SPS HARQ-ACK is multiplexed with other channels in a symbol of the unusable symbol type includes:

[0136] A131、if the first SPS HARQ-ACK is multiplexed with other channels in symbols of the unavailable symbol type, determining the transmission manner of the first SPS HARQ-ACK as transmission or dropping;

[0137] It should be noted that in this case, it can be understood that if the first SPS HARQ-ACK is multiplexed with other channels in symbols of the unavailable symbol type (for example, multiplexing uses PUCCH resources other than the PUCCH resources configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, or uses PUSCH resources), the transmission of the first SPS HARQ-ACK or the transmission of the first SPS HARQ-ACK is performed. The transmission manner in this case is determined based on whether the multiplexed resource is valid.

[0138] A132、if the first SPS HARQ-ACK is not multiplexed with other channels in symbols of the unavailable symbol type, determining the transmission manner of the first SPS HARQ-ACK as delayed transmission;

[0139] It should be noted that in this case, it can be understood that if the first SPS HARQ-ACK is not multiplexed with other channels in symbols of the unavailable symbol type (for example, using PUCCH resources configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN), the transmission of the first SPS HARQ-ACK is delayed, that is, the first SPS HARQ-ACK is not transmitted first, and the transmission of the first SPS HARQ-ACK is performed at other opportunities.

[0140] In some embodiments, in the case of delayed transmission, the method further comprises at least one of B11-B13:

[0141] B11, determining whether the first SPS HARQ-ACK is multiplexed with other channels on symbols of the unavailable symbol type, in the case of multiplexing with other channels, determining the transmission manner of the first SPS HARQ-ACK as transmission or dropping, and in the case of not multiplexing with other channels, determining the transmission manner of the first SPS HARQ-ACK as delayed transmission;

[0142] It should be noted that this case can be understood as follows: in the case that at least one of A11-A13 above is determined to be delayed transmission, for the symbol type that is not available, first determine whether the first SPS HARQ-ACK is multiplexed with other channels, in the case that multiplexing is possible (for example, after multiplexing, a PUCCH resource other than the PUCCH resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN is used, or a PUSCH resource is used), the terminal can transmit the first SPS HARQ-ACK or discard the SPS HARQ-ACK; in the case that multiplexing is not possible (for example, the PUCCH resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN is used), the terminal needs to delay the transmission of the SPS HARQ-ACK.

[0143] B12, determining that the transmission mode on the symbol of the symbol type that is not available for the first SPS HARQ-ACK is delayed transmission;

[0144] It should be noted that this case can be understood as follows: in the case that at least one of A11-A13 above is determined to be delayed transmission, for the symbol type that is not available, the terminal needs to delay the transmission of the SPS HARQ-ACK.

[0145] B13, determining that the transmission mode on the symbol of the symbol type that is available for the first SPS HARQ-ACK is transmission, delayed transmission or discard;

[0146] It should be noted that in this case, if at least one of A11-A13 is determined to be delayed transmission, for the available symbol type, if the first SPS HARQ-ACK is not multiplexed with other channels (for example, using the PUCCH resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN), and the resource for transmitting the first SPS HARQ-ACK is valid, it is determined that the transmission mode of the first SPS HARQ-ACK is transmission; if the first SPS HARQ-ACK is not multiplexed with other channels (for example, using the PUCCH resource configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN), and the resource for transmitting the first SPS HARQ-ACK is invalid (for example, and semi-statically configured downlink symbols, SSB and / or CORESET#0 conflict), it is determined that the transmission mode of the first SPS HARQ-ACK is delayed transmission or discarded; if the first SPS HARQ-ACK is multiplexed with other channels (for example, after multiplexing, using PUCCH resources other than the PUCCH resources configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, or using PUSCH resources), and the multiplexed resource for transmitting the first SPS HARQ-ACK is valid, it is determined that the transmission mode of the first SPS HARQ-ACK is transmission; if the first SPS HARQ-ACK is multiplexed with other channels (for example, after multiplexing, using PUCCH resources other than the PUCCH resources configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, or using PUSCH resources), and the multiplexed resource for transmitting the first SPS HARQ-ACK is invalid, it is determined that the transmission mode of the first SPS HARQ-ACK is discarded.

[0147] The specific application implementation of the embodiments of the present disclosure is described in detail as follows taking the first SPS HARQ-ACK as an example of a SPS HARQ-ACK#1 that only supports transmission in one symbol type and is configured to be delayed.

[0148] Application case one,

[0149] Mainly includes the following cases:

[0150] In the case where the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type available to the SPS HARQ-ACK#1, it is determined that the transmission mode of the SPS HARQ-ACK#1 is transmission, delayed transmission or discarded;

[0151] In the case that the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type unavailable for the SPS HARQ-ACK#1, it is determined that the transmission manner of the SPS HARQ-ACK#1 is dropping;

[0152] In the case of delayed transmission, it is determined that the transmission manner on the symbol of the symbol type unavailable for the SPS HARQ-ACK#1 is delayed transmission, and the transmission manner on the symbol of the symbol type available for the SPS HARQ-ACK#1 is transmission, delayed transmission or dropping.

[0153] For example, for an SBFD terminal, it is assumed that the non-SBFD symbol is the symbol type available for SPS HARQ-ACK. As shown in FIG. 2, slots 1, 2, 3, 6, 7 and 8 are SBFD symbols, slot 4 is the initial transmission position of SPS HARQ-ACK#11, the symbol corresponding to the slot 4 is the symbol type available for SPS HARQ-ACK#11, and the SPS HARQ-ACK#11 does not conflict with a specific symbol (for example, a semi-statically configured downlink symbol, SSB and / or CORESET#0, etc.), so the SPS HARQ-ACK#11 can be normally transmitted. Slot 8 is the initial transmission position of SPS HARQ-ACK#12, the symbol corresponding to the slot 8 is the symbol type unavailable for SPS HARQ-ACK#12, so the SPS HARQ-ACK#12 is directly dropped.

[0154] Case two,

[0155] Mainly includes the following cases:

[0156] In the case that the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type available for the SPS HARQ-ACK#1, it is determined that the transmission manner of the SPS HARQ-ACK#1 is transmission, delayed transmission or dropping;

[0157] In the case that the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type unavailable for the SPS HARQ-ACK#1, it is determined that the transmission manner of the SPS HARQ-ACK#1 is delayed transmission;

[0158] In the case of delayed transmission, it is determined that the transmission manner on the symbol of the symbol type unavailable for the SPS HARQ-ACK#1 is delayed transmission, and the transmission manner on the symbol of the symbol type available for the SPS HARQ-ACK#1 is transmission, delayed transmission or dropping.

[0159] For example, for an SBFD terminal, assuming that the non-SBFD symbol is the symbol type available for SPS HARQ-ACK. As shown in FIG. 3, time slot 1, time slot 2, time slot 3, time slot 6, time slot 7 and time slot 8 are SBFD symbols, time slot 4 is the initial transmission position of SPS HARQ-ACK#21, the symbol corresponding to the time slot 4 is the available symbol type of SPS HARQ-ACK#21, and the SPS HARQ-ACK#21 does not conflict with a specific symbol (semi-statically configured downlink symbol, SSB and / or CORESET#0, etc.), so it can be normally transmitted. Time slot 7 is the initial transmission position of SPS HARQ-ACK#22, the symbol corresponding to the time slot 7 is the unavailable symbol type of SPS HARQ-ACK#22, so the delayed transmission of SPS HARQ-ACK#22 is performed. The SBFD terminal determines the availability of each subsequent time slot / sub-slot in time order until the target time slot available is determined. The symbol corresponding to the next time slot 8 is the unavailable symbol type of SPS HARQ-ACK#22, so the delay of SPS HARQ-ACK#22 continues. The symbol corresponding to the next time slot 9 is the available symbol type of SPS HARQ-ACK#22, and since SPS HARQ-ACK#22 in time slot 9 is not multiplexed with other channels and does not conflict with a specific symbol (semi-statically configured downlink symbol, SSB and / or CORESET#0, etc.), it can be normally transmitted.

[0160] Case three,

[0161] Mainly includes the following cases:

[0162] In the case that the symbol type at the initial transmission position of SPS HARQ-ACK#1 is the available symbol type of SPS HARQ-ACK#1, it is determined that the transmission mode of SPS HARQ-ACK#1 is transmission, delayed transmission or discard;

[0163] In the case that the symbol type at the initial transmission position of SPS HARQ-ACK#1 is the unavailable symbol type of SPS HARQ-ACK#1, if SPS HARQ-ACK#1 is multiplexed with other channels in the symbol of the unavailable symbol type, it is determined that the transmission mode of SPS HARQ-ACK#1 is transmission or discard, and if SPS HARQ-ACK#1 is not multiplexed with other channels in the symbol of the unavailable symbol type, it is determined that the transmission mode of SPS HARQ-ACK#1 is delayed transmission;

[0164] Further, in the case of the delayed transmission of the above-mentioned case, it is determined whether the SPS HARQ-ACK#1 is multiplexed with other channels on the symbol of the symbol type in which the SPS HARQ-ACK#1 is unavailable, and in the case of multiplexing with other channels, it is determined that the transmission mode of the SPS HARQ-ACK#1 is transmission or dropping, and in the case of not multiplexing with other channels, it is determined that the transmission mode of the SPS HARQ-ACK#1 is delayed transmission.

[0165] For example, for an SBFD terminal, it is assumed that the non-SBFD symbol is the symbol type in which the SPS HARQ-ACK is available. As shown in FIG. 4, slots 1, 2, 3, 6, 7, and 8 are SBFD symbols, and slot 5 is the initial transmission position of SPS HARQ-ACK#31, the symbol corresponding to the slot 5 is the available symbol type of SPS HARQ-ACK#31, but conflicts with a specific symbol (semi-statically configured downlink symbol, SSB, and / or CORESET#0, etc.), and therefore needs to be delayed. The SBFD terminal determines the availability of each subsequent slot / sub-slot in time order until a target slot is determined. Since slots 6 and 7 are both symbol types in which SPS HARQ-ACK#31 is unavailable, and are not multiplexed with dynamic HARQ-ACK or PUSCH, the delay continues, and in slot 8, since SPS HARQ-ACK#31 can be multiplexed on PUSCH, slot 8 is the target slot, and the delay is no longer performed.

[0166] Slot 7 is the initial transmission position of SPS HARQ-ACK#32, and the symbol corresponding to the slot 7 is the symbol type in which SPS HARQ-ACK#32 is unavailable, and therefore needs to be delayed. In the next slot 8, since SPS HARQ-ACK#32 can be multiplexed on PUSCH, slot 8 is the target slot, and the delay is no longer performed.

[0167] Case four,

[0168] Mainly includes the following cases:

[0169] In the case where the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type in which the SPS HARQ-ACK#1 is available, it is determined that the transmission mode of the SPS HARQ-ACK#1 is transmission, delayed transmission, or dropping; further, in the case of delayed transmission in this case, it is determined that the transmission mode on the symbol of the symbol type in which the SPS HARQ-ACK#1 is unavailable is delayed transmission; and it is determined that the transmission mode on the symbol of the symbol type in which the SPS HARQ-ACK#1 is available is transmission, delayed transmission, or dropping;

[0170] In the case that the symbol type at the initial transmission position of the SPS HARQ-ACK#1 is the symbol type unavailable for the SPS HARQ-ACK#1, if the SPS HARQ-ACK#1 is multiplexed with other channels in the symbol of the symbol type unavailable, it is determined that the transmission mode of the SPS HARQ-ACK#1 is transmission or discard, and if the SPS HARQ-ACK#1 is not multiplexed with other channels in the symbol of the symbol type unavailable, it is determined that the transmission mode of the SPS HARQ-ACK#1 is delayed transmission; further, in the case of delayed transmission in this case, it is determined whether the SPS HARQ-ACK#1 is multiplexed with other channels on the symbol of the symbol type unavailable, in the case of multiplexing with other channels, it is determined that the transmission mode of the SPS HARQ-ACK#1 is transmission or discard, and in the case of not multiplexing with other channels, it is determined that the transmission mode of the SPS HARQ-ACK#1 is delayed transmission.

[0171] For example, for an SBFD terminal, assuming that the non-SBFD symbol is the symbol type available for SPS HARQ-ACK. As shown in FIG. 5, time slot 1, time slot 2, time slot 3, time slot 6, time slot 7 and time slot 8 are SBFD symbols, and time slot 5 is the initial transmission position of SPS HARQ-ACK#41, the symbol corresponding to the time slot 5 is the available symbol type of SPS HARQ-ACK#41, but conflicts with a specific symbol (semi-statically configured downlink symbol, SSB and / or CORESET#0, etc.), so it needs to be delayed. The SBFD terminal determines the availability of each subsequent time slot / sub-slot in time order until a target time slot is determined. Since time slot 6 and time slot 7 are both symbol types unavailable for SPS HARQ-ACK#31, it is delayed to time slot 9. Since SPS HARQ-ACK#31 is not multiplexed with other channels and does not conflict with a specific symbol (semi-statically configured downlink symbol, SSB and / or CORESET#0, etc.) if it is transmitted in time slot 9, time slot 9 is the target time slot and can be normally transmitted.

[0172] Time slot 7 is the initial transmission position of SPS HARQ-ACK#42, and the symbol corresponding to the time slot 7 is the symbol type unavailable for SPS HARQ-ACK#42, so it is delayed. In the next time slot 8, since SPS HARQ-ACK#42 can be multiplexed on PUSCH, time slot 8 is the target time slot and no longer delayed.

[0173] It should be noted that at least one embodiment of the present disclosure provides an SPS HARQ-ACK transmission method. For an SBFD terminal, when SPS HARQ-ACK is transmitted only in one symbol type and SPS HARQ-ACK delay is supported, the transmission rule of SPS HARQ-ACK is given, thereby perfecting the function of the SBFD system, ensuring the accurate transmission of SPS HARQ-ACK, and ensuring the communication reliability.
