[0003] For a given SPS Physical Downlink Shared Channel (PDSCH), if the time-domain resources determined according to the pre-configured feedback time slot cannot be used to transmit the feedback information of the SPS PDSCH, then the feedback information of the SPS PDSCH will not be transmitted. The inability to transmit the feedback information of the SPS PDSCH will lead to a decrease in system efficiency. Summary of the Invention

[0008] Fourthly, a data transmission apparatus is provided, comprising: an acquisition unit, configured to acquire a set of feedback information associated with a first time-domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs); where M is an integer greater than or equal to 1; a determination unit, configured to determine target feedback information from the set of feedback information; the target feedback information includes: feedback information of the first N SPS PDSCHs among the feedback information of the M SPS PDSCHs; where N is an integer greater than or equal to 1 and less than or equal to M; and a receiving unit, configured to receive the target feedback information on the first time-domain resource.

[0031] The technical solutions of this application will be described in detail below through embodiments and in conjunction with the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that in the examples of this application, "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the technical solutions described in the embodiments of this application can be arbitrarily combined without conflict. "Multiple" or "multiple" in the embodiments of this application can refer to at least two, at least two, etc., respectively.

[0032] In New Radio (NR) systems, data transmission methods can include dynamic transmission and semi-persistent / semi-static transmission. Dynamic transmission is characterized by parameters for each data transmission being indicated by the corresponding Downlink Control Information (DCI). The DCI may include information such as the physical resources used by the PDSCH and / or the Hybrid Automatic Repeat reQuest (HARQ) process number. Semi-persistent / semi-static transmission is characterized by semi-persistent / semi-static configuration of transmission resources and transmission methods. The DCI is used to activate / release the corresponding SPS transmission. Once activated, subsequent transmissions do not require physical layer signaling (e.g., DCI) scheduling.

[0033] In some implementations, a terminal device can be configured with up to one set of SPS transmission parameters, with a minimum period of 10ms. The network device configures the SPS transmission parameters via higher-layer signaling, including at least one of the following: period, time-domain resources, and Physical Uplink Control Channel (PUCCH) resources for acknowledgment / negative ACK / NACK transmission. Since the minimum SPS transmission period is 10ms, and the maximum supported uplink / downlink handover period is 10ms, at least one defined uplink transmission resource must be included within the 10ms period. Therefore, the SPS PDSCH can employ independent feedback, meaning one SPS PDSCH corresponds to one PUCCH carrying its ACK / NACK information. The PUCCH configured by the network device for transmitting ACK / NACK on the SPS PDSCH can be PUCCH format 0 or PUCCH format 1, where PUCCH format 0 or PUCCH format 1 can carry a maximum of 2 bits of ACK / NACK information. Then, the network device can activate or deactivate SPS via downlink control signaling (DCI). The activation signaling will further indicate some parameters of the SPS transmission, such as frequency domain resources and / or feedback time slots. The feedback time slot can be called the time domain offset, denoted by k1, where k1 represents the time slot interval between the time slot where the SPS PDSCH is located and the time slot where the ACK / NACK transmission of the SPS PDSCH is located. Once SPS transmission is activated, without dynamic scheduling within the same time resources, the network device will always send an SPS PDSCH, and the terminal device will always send the ACK / NACK information corresponding to the SPS PDSCH. In the embodiments of this application, any feedback information can be ACK / NACK information, HARQ-ACK information, or a HARQ-ACK codebook.

[0034] Figure 1 A schematic diagram illustrating the relationship between SPS PDSCH and PUCCH within an SPS cycle is provided for embodiments of this application, as shown below. Figure 1 As shown, in the time dimension t, within each SPS period, the ACK / NACK information for the SPS PDSCH can be transmitted on the PUCCH after the time domain offset k1.

[0035] To better support ultra-reliable low-latency communication, the SPS period will be shortened, with a minimum of 1ms. For an SPSPDSCH, if the time-domain resources determined according to the pre-configured feedback time slot (k1) cannot be used to transmit the PUCCH, such as if the time-domain symbols occupied by the PUCCH are downlink symbols, then the ACK / NACK information of the SPS PDSCH will not be transmitted.

[0036] To avoid system efficiency degradation caused by discarded ACK / NACK messages corresponding to SPS PDSCHs, enhanced feedback for SPS PDSCHs can be supported. For example, SPS ACK / NACK deferring (Deferring HARQ-ACK) can be supported. That is, if an SPS PDSCH received in time slot / sub-time slot n cannot transmit its corresponding ACK / NACK message in a PUCCH after time slot / sub-time slot n+k1 (where k1 can be pre-configured by the network device, e.g., through higher-layer signaling configuration or indicated in the activation signaling DCI), the ACK / NACK message is deferred to time slot / sub-time slot n+k1+k1. defer Transmission takes place within the specified timeframe.

[0037] To reduce the complexity of terminal device implementation, the following PDSCH timing relationship is still defined for data processing within a single carrier:

[0038] Figure 2 A schematic diagram illustrating the relationship between PDSCH and the feedback A / N is provided for an embodiment of this application, as shown below. Figure 2 As shown, in the time dimension t, the terminal device receives a PDSCH 1, whose corresponding HARQ process number is X. Before the terminal device sends the ACK / NACK (A / N) feedback information corresponding to this PDSCH 1, the terminal device does not expect the network device to schedule a new PDSCH 2, whose HARQ process number is the same as that of PDSCH 1. That is, after a downlink (DL) HARQ process transmission, but before the corresponding ACK / NACK feedback information is sent, the network device cannot reuse the HARQ process number of this PDSCH 1 for data transmission.

[0039] Figure 3 Another schematic diagram illustrating the relationship between PDSCH and the feedback A / N provided for embodiments of this application is shown below. Figure 3 As shown, in the time dimension t, the terminal device receives PDSCH 1 in time slot i, and its corresponding ACK / NACK information is transmitted through time slot j. The terminal device does not expect to receive PDSCH 2, whose start symbol is after the start symbol of PDSCH 1, but the corresponding ACK / NACK (A / N) information is transmitted through a time slot before time slot j. That is, the feedback of a PDSCH scheduled later cannot be earlier.

[0040] However, the PDSCH timing may be disrupted after the introduction of the SPS ACK / NACK information delay method.

[0041] Figure 4 A schematic diagram of SPS HARQ-ACK feedback provided for an embodiment of this application, as shown below. Figure 4 As shown, the terminal device can be configured with two SPS configurations: SPS configuration 1 and SPS configuration 2. The pre-configured feedback time slot k1 is always one time slot. Additionally, the network device is configured with two PUCCH resources for transmitting SPS ACK / NACK. PUCCH 1 (or PUCCH resource 1) is used to transmit 1 or 2 bits of information, and PUCCH 2 (or PUCCH resource 2) is used to transmit more than 2 bits of information. Uplink resources are configured in Slot n+3 and Slot n+5.

[0042] According to k1=1, the feedback information of SPS PDSCH 0 and SPS PDSCH 1 in slot n is transmitted in slot n+1. However, this slot is a downlink slot and cannot transmit feedback information, so the corresponding feedback information needs to be postponed. The feedback information of SPS PDSCH 2 and SPS PDSCH 3 in slot n+1 is transmitted in slot n+2. However, this slot is a downlink slot and cannot transmit feedback information, so the corresponding feedback information needs to be postponed. The feedback information of SPS PDSCH 4 and SPS PDSCH 5 in slot n+2 is transmitted in slot n+3. If only the 2-bit feedback information corresponding to SPS PDSCH 4 and SPS PDSCH 5 is transmitted in slot n+3, PUCCH resource 1 can be used. The time domain resource occupied by PUCCH resource 1 is an uplink resource and can be transmitted. However, the feedback information of SPS PDSCH 0 to 3 will be postponed to slot n+5 for transmission. This results in out-of-order disorder, meaning the order is broken. Figure 3 The corresponding timing constraints.

[0043] To at least address the aforementioned issues, embodiments of this application provide a data transmission method, apparatus, device, storage medium, chip, and product.

[0044] The term "terminal device" in this application can be referred to as Terminal, User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc. Specifically, terminal devices can include mobile phones, tablets, computers with wireless transceiver capabilities, handheld computers, desktop computers, personal digital assistants, portable media players, smart speakers, navigation devices, smartwatches, smart glasses, smart necklaces and other wearable devices, pedometers, digital TVs, Virtual Reality (VR) terminal devices, Augmented Reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and vehicles, in-vehicle equipment, or in-vehicle modules in vehicle networking systems, etc.

[0045] The network equipment used in this application can be a network-side device that communicates wirelessly with terminal devices, such as a Wireless-Fidelity (Wi-Fi) access point, an evolved base station, a next-generation communication base station, such as a 5G gNB or small cell, micro cell, or transmission reception point (TRP), or it can be a relay station, access point, vehicle-mounted equipment, or wearable device, etc.

[0046] The following describes the data processing method provided in the embodiments of this application. During implementation, the executing entity of the following method may include a processor or a chip, which can be applied in a terminal device or a network device. Alternatively, the executing entity may be a terminal device or a network device.

[0047] Figure 5 This is a schematic diagram illustrating the implementation flow of a data transmission method provided in an embodiment of this application, as shown below. Figure 5 As shown, this method is applied to a terminal device, and the method includes:

[0048] S501. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling (SPS) physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0049] Any time-domain resource mentioned in the embodiments of this application (e.g., a first time-domain resource, or any one of the second, third, or one or more time-domain resources described below, etc.) may include a frame, a subframe, a time slot, a sub-time slot, or Q time-domain symbols; Q is an integer greater than or equal to 1. The Q time-domain symbols can be time-domain symbols within a single time slot. In implementation, the Q time-domain symbols can be any number of time-domain symbols from 1 to 13. For example, the Q time-domain symbols can be 1 time-domain symbol, 2 time-domain symbols, 4 time-domain symbols, 8 time-domain symbols, etc.

[0050] Feedback information from M SPS PDSCHs may include: feedback information from one or more SPS PDSCH configurations; at least one of the period, time-domain resources, and frequency-domain resources of different SPS PDSCH configurations may be different. M can be 1 or an integer greater than or equal to 2.

[0051] In some implementations, different configurations of SPS PDSCH correspond to different services. For example, in communication or network services, the SPS PDSCH period can be longer, and time-domain and / or frequency-domain resources can be more abundant; in IoT services, the SPS PDSCH period can be shorter, and time-domain and / or frequency-domain resources can be less abundant. Figure 4 The diagram illustrates two configurations of SPS PDSCH: SPS Configuration 1 and SPS Configuration 2. The period of the SPS PDSCH can be one or more subframes, one or more time slots, one or more sub-time slots, or R time-domain symbols, etc. R is an integer greater than or equal to 1.

[0052] A single time-domain resource can include one or more configured SPS PDSCHs, for example, such as Figure 4 As shown, Slot n or Slot n+1 includes the PDSCH for SPS configuration 1 and the PDSCH for SPS configuration 2. During implementation, network devices can activate different SPS configurations via different DCIs.

[0053] The feedback information of the M SPS PDSCHs can be arranged sequentially. For example, the feedback information of the M SPS PDSCHs can be arranged sequentially based on at least one of the following methods: chronological order, ascending order of the HARQ process number of the SPS PDSCHs, ascending order of the SPS configuration number, ascending order of the carrier number of the carrier on which the SPS PDSCH is located, etc. For example, if the time domain position of the first SPS PDSCH is before the time domain position of the second SPS PDSCH, then the first SPS PDSCH is arranged before the second SPS PDSCH. As another example, if the time domain position of the first SPS PDSCH is the same as that of the second SPS PDSCH, but the HARQ process number of the first SPS PDSCH is less than the HARQ process number of the second SPS PDSCH, then the first SPS PDSCH is arranged before the second SPS PDSCH.

[0054] In some implementations, the feedback information of any one of the M SPS PDSCHs (or the feedback information corresponding to any one SPS PDSCH) can be ACK / NACK information or HARQ-ACK information.

[0055] S502. Determine the target feedback information from the set of feedback information; the target feedback information includes: the feedback information of the first N SPS PDSCHs out of the feedback information of M SPS PDSCHs; N is an integer greater than or equal to 1 and less than or equal to M.

[0056] When M is 1, the feedback information of the first N SPS PDSCHs can be the feedback information of the 1 SPS PDSCH.

[0057] In some implementations, the feedback information of the first N SPS PDSCHs can be the feedback information with the earliest time among the feedback information of M SPS PDSCHs, and / or the feedback information with the earliest HARQ process number of the SPS PDSCH, and / or the feedback information with the earliest SPS configuration number, and / or the feedback information with the earliest carrier number of the carrier on which the SPS PDSCH is located.

[0058] S503, Transmit target feedback information on the first time domain resource.

[0059] The terminal device can transmit target feedback information on the PUCCH corresponding to the first time domain resource. For example, the terminal device can transmit target feedback information on a specific PUCCH within the first time domain resource. The terminal device can send target feedback information to the network device on the first time domain resource.

[0060] In some implementations, a PUCCH of the first time-domain resource may transmit only target feedback information. In other implementations, a PUCCH of the first time-domain resource may transmit not only target feedback information but also other control information; this application does not limit this aspect.

[0061] The first time-domain resource may be configured with one or more PUCCH resources. For example, the first time-domain resource may be configured with at least one of the following PUCCH resources: a first PUCCH resource, a second PUCCH resource, a third PUCCH resource, and a fourth PUCCH resource. In other embodiments, the first time-domain resource may be configured with more than four PUCCH resources.

[0062] Within any time-domain resource (including the first time-domain resource), the attribute information of different PUCCH resources can be different. The attribute information of the same PUCCH resource configured in different time-domain resources can be the same. Attribute information may include at least one of the following: the time-domain resources occupied, the frequency-domain resources occupied, and the number of bits that can be carried. For example, such as... Figure 4 As shown, the attribute information of PUCCH 1 and PUCCH 2 in Slot n+3 can be different. In Slot n+3 and Slot n+5, the attribute information of the two PUCCH 1s can be the same, and the attribute information of the two PUCCH 2s can be the same.

[0063] In some implementations, if there are no resources on the first time domain resource capable of transmitting target feedback information, for example, if the first time domain resource does not include uplink resources and / or flexible resources, or if the first time domain resource may include not only uplink resources and / or flexible resources, but also unavailable resources, and the PUCCH in the first time domain resource includes unavailable resources (i.e., resources that cannot be used to transmit feedback information, wherein an implementation in which the PUCCH includes unavailable resources may include: all or part of the resources corresponding to the PUCCH are unavailable resources), then the terminal device will not transmit target feedback information on the first time domain resource, thereby postponing the transmission of the entire set of feedback resources to one or more time domain resources after the first time domain resource.

[0064] In this embodiment, target feedback information is determined from the set of feedback information associated with the first time domain resource, and the target feedback information is transmitted on the first time domain resource. The target feedback information includes the feedback information of the first N SPS PDSCHs out of the feedback information of M SPS PDSCHs. This allows the feedback information of the SPS PDSCHs to be transmitted sequentially according to the order of their feedback information. This not only ensures that the feedback information of each SPS PDSCH can be transmitted, but also avoids the situation where the SPS PDSCHs scheduled later are fed back first, which would cause out-of-order transmission.

[0065] In some embodiments, the set of feedback information may include: delayed first feedback information associated with a first time-domain resource; the first feedback information includes: specified feedback information transmitted on a second time-domain resource based on a time-domain offset; the second time-domain resource precedes the first time-domain resource, and there is no available resource in the second time-domain resource for transmitting the specified feedback information.

[0066] The second time-domain resource may include one or more time-domain resources. The second time-domain resource may be an adjacent time-domain resource to the first time-domain resource, or the second time-domain resource may be separated from the first time-domain resource by one or more time-domain resources.

[0067] like Figure 4 As shown, taking Slot n+3 as the first time-domain resource as an example, the feedback information of SPPS PDSCH 0 and SPPS PDSCH 1, which can be determined based on the time-domain offset, is transmitted in Slot n+1. However, Slot n+1 is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information (feedback information of SPPS PDSCH 0 and SPPS PDSCH 1) needs to be postponed. The feedback information of SPPS PDSCH 2 and SPPS PDSCH 3 is transmitted in Slot n+2. However, Slot n+2 is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information (feedback information of SPPS PDSCH 0-3) needs to be postponed to Slot n+3. Thus, it can be determined that the feedback information of SPPS PDSCH 0, SPPS PDSCH 1, SPPS PDSCH 2, and SPPS PDSCH 3 is the postponed first feedback information associated with the first time-domain resource.

[0068] In other embodiments, the set of feedback information may include: undelayed second feedback information associated with the first time-domain resource; the second feedback information includes: feedback information transmitted on the first time-domain resource based on the time-domain offset.

[0069] like Figure 4As shown, taking Slot n+3 as an example, the feedback information of SPSPDSCH 4 and SPSPDSCH 5, which can be determined based on the time domain offset, is transmitted in Slot n+3. Thus, the feedback information of SPSPDSCH 4 and SPSPDSCH 5 can be determined as the undelayed second feedback information associated with the first time domain resource.

[0070] In some other implementations, the feedback information set may include: a delayed first feedback information associated with the first time domain resource, and a non-delayed second feedback information associated with the first time domain resource.

[0071] In some implementations, different configurations of SPS PDSCH can correspond to different time-domain offsets.

[0072] like Figure 4 As shown, through the data transmission method provided in this application embodiment, the PUCCH resource in the first time domain resource used for transmitting feedback information of SPS PDSCH may include PUCCH 1 and PUCCH 2. The time domain resource occupied by PUCCH 1 is an uplink resource, which can transmit feedback information of SPS PDSCH. Therefore, based on the fact that PUCCH 1 can carry 2 bits, the target feedback information is determined to include the feedback information of SPS PDSCH 0 and SPS PDSCH 1. The time domain resource occupied by PUCCH 2 includes unavailable resources (e.g., downlink resources) and cannot transmit feedback information of SPS PDSCH.

[0073] In some embodiments, the first target resource in the first time domain resource for transmitting target feedback information is a resource corresponding to the target number of bits; the target number of bits belongs to the number of bits that one or more uplink resources can carry respectively, the target number of bits is closest to the number of bits in the feedback information set, and the target number of bits is greater than or equal to the number of bits in the feedback information set; the one or more uplink resources are uplink resources available in the first time domain resource for transmitting feedback information.

[0074] In other embodiments, the first target resource in the first time domain resource used for transmitting target feedback information can be the resource corresponding to the maximum number of bits among the number of bits that one or more available uplink resources can carry, and the number of bits that the first target resource can carry is less than or equal to the number of bits of the feedback information set.

[0075] It should be noted that the one or more uplink resources mentioned anywhere in the embodiments of this application can be available resources for transmitting uplink data. The symbols occupied or corresponding to the available resources for transmitting uplink data can be uplink symbols, or they can be uplink symbols and / or flexible symbols. Uplink symbols and / or flexible symbols can be semi-statically configured, or they can be dynamically indicated.

[0076] During implementation, the feedback information of the first N SPS PDSCHs can be determined based on time-domain resources as the smallest unit. For example, the feedback information of the first N SPS PDSCHs can be the feedback information of all SPS PDSCHs in one or more time-domain resources.

[0077] The feedback information for M SPS PDSCHs includes: feedback information for all SPS PDSCHs in one or more time-domain resources that precede and are associated with the first time-domain resource.

[0078] The feedback information of the first N SPS PDSCHs includes: the feedback information of all SPS PDSCHs in the first P time-domain resources of one or more time-domain resources; P is an integer greater than or equal to 1.

[0079] Figure 6 This is a schematic diagram illustrating the implementation flow of another data transmission method provided in an embodiment of this application, as shown below. Figure 6 As shown, this method is applied to a terminal device, and the method includes:

[0080] S601. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling (SPS) physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0081] S602. Determine the feedback information set, the feedback information of all SPSPDSCH in the first P time domain resources of one or more time domain resources, corresponding to the second target resource, and the second target resource is allowed to be transmitted in the first time domain resource; one or more time domain resources are before the first time domain resource and associated with the first time domain resource.

[0082] In any embodiment of this application, one or more time-domain resources associated with the first time-domain resource can be determined based on the time-domain offset. In some embodiments, the one or more time-domain resources associated with the first time-domain resource can be the time-domain resources containing all SPS PDSCHs corresponding to each feedback information in the feedback information set associated with the first time-domain resource.

[0083] In this step, the second target resource is allowed to be transmitted in the first time domain resource, which may include: data on the second target resource (including feedback information of all SPS PDSCH in the first P time domain resources) is allowed to be transmitted in the first time domain resource, and / or the second target resource is an uplink transmission resource and / or a flexible transmission resource.

[0084] One implementation of allowing the second target resource to be transmitted in the first time domain resource is as follows: the number of bits of feedback information of all SPS PDSCH in the first P time domain resources is less than or equal to the number of bits that the second target resource can carry, and the second target resource is an uplink resource and / or a flexible resource.

[0085] The uplink resources mentioned in the embodiments of this application can refer to the symbols occupied by the resource as uplink symbols, and the flexible resources can refer to the symbols occupied by the resource as flexible symbols.

[0086] S603. Determine the feedback information of all SPS PDSCH in the first P+1 time domain resources of one or more time domain resources, corresponding to the third target resource, and the third target resource is not allowed to be transmitted in the first time domain resource; the number of bits that the third target resource can carry is greater than the number of bits that the second target resource can carry.

[0087] In some embodiments, the third target resource is not allowed to be transmitted in the first time domain resource, which may include: the number of bits of feedback information of all SPS PDSCH in the first P+1 time domain resources is greater than the number of bits that the third target resource can carry; or, the third target resource includes unavailable resources.

[0088] For example, the number of bits for the feedback information of all SPS PDSCH in the first P+1 time domain resources is 4 bits, but the number of bits that the third target resource can carry is 2 bits, thus determining that the third target resource is not allowed to be transmitted in the first time domain resource.

[0089] In this embodiment, unavailable resources may include at least one of the following: downlink resources, uplink / downlink handover protection resources, and network-configured unavailable resources. The symbols occupied by unavailable resources may include downlink symbols, uplink / downlink handover protection symbols, and network-configured unavailable symbols. The downlink symbols may include semi-statically configured downlink symbols, or a combination of semi-static and dynamically configured downlink symbols.

[0090] S604. Determine the feedback information of all SPS PDSCH in the first P time-domain resources as the target feedback information.

[0091] S605, Transmit target feedback information on the first time domain resource.

[0092] by Figure 4 For example, for Figure 6The corresponding embodiments are illustrated by example. Figure 4 In this context, PUCCH resource 1 can carry 2 bits, and PUCCH resource 2 can carry 7 bits.

[0093] Feedback information for SPS PDSCH 0 and SPS PDSCH 1 in Slot n is transmitted in Slot n+1. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 2 and SPS PDSCH 3 in Slot n+1 is transmitted in Slot n+2. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 4 and SPS PDSCH 5 in Slot n+2 is transmitted in Slot n+3.

[0094] If only the 2-bit feedback information corresponding to SPS PDSCH 0 and SPS PDSCH 1 is transmitted in Slot n+3, PUCCH resource 1 is used. PUCCH resource 1 occupies only uplink symbols in the time domain, meaning it is available. However, transmitting the 4-bit feedback information corresponding to SPS PDSCH 0-3 in Slot n+3 requires the use of PUCCH resource 2. But PUCCH resource 2 occupies downlink symbols in the time domain, meaning it is unavailable. Therefore, the terminal device determines:

[0095] (1) The 2-bit feedback information corresponding to SPS PDSCH 0 and SPS PDSCH 1 is transmitted in Slot n+3;

[0096] (2) Feedback information from SPS PDSCH 2-5 is further postponed to Slot n+5.

[0097] If only 2-bit feedback information corresponding to SPS PDSCH 2 and SPS PDSCH 3 is transmitted in Slot n+5, PUCCH resource 1 is used, and all time-domain symbols occupied by PUCCH resource 1 are uplink symbols, meaning PUCCH resource 1 is available. If only 4-bit feedback information corresponding to SPS PDSCH 2, 3, 4, and 5 is transmitted in Slot n+5, PUCCH resource 2 is used, and all time-domain symbols occupied by PUCCH resource 2 are uplink symbols, meaning PUCCH resource 2 is available. If only 5-bit feedback information corresponding to SPS PDSCH 2, 3, 4, 5, and 6 is transmitted in Slot n+5, PUCCH resource 2 is used, and all time-domain symbols occupied by PUCCH resource 2 are uplink symbols, meaning PUCCH resource 2 is available. If only 7-bit feedback information corresponding to SPS PDSCH 2, 3, 4, 5, 6, 7, and 8 is transmitted in Slot n+5, PUCCH resource 2 is used, and all time-domain symbols occupied by PUCCH resource 2 are uplink symbols, meaning PUCCH resource 2 is available. Then the terminal device is determined as follows:

[0098] The 7-bit feedback information corresponding to SPS PDSCH2-8 is transmitted in Slot n+5.

[0099] This embodiment determines the transmission of HARQ-ACK bits using time slots as the smallest unit. It can also be extended to use HARQ-ACK bits corresponding to one PDSCH as the smallest unit.

[0100] The effect of this method is that it prioritizes the transmission of SPS ACK / NACK according to the time sequence, ensuring that the transmissions are sent as early as possible without causing out-of-order delivery, thus breaking the [previous principle]. Figure 3 The corresponding timing constraints are simple to implement on terminal devices. No additional SPSACK / NACK feedback latency is introduced.

[0101] During implementation, the feedback information of the first N SPS PDSCHs can be determined based on the HARQ-ACK bit corresponding to a PDSCH as the smallest unit.

[0102] The feedback information of M SPS PDSCHs includes: the feedback information of all SPS PDSCHs in one or more time-domain resources that precede the first time-domain resource and are associated with the first time-domain resource;

[0103] In some implementations, if the first time-domain resource is associated with another time-domain resource, the feedback information of the first N SPS PDSCHs may include: feedback information of a portion of the SPS PDSCHs in the time-domain resource associated with the first time-domain resource.

[0104] In other implementations, if the first time-domain resource is associated with multiple time-domain resources, the feedback information of the first N SPS PDSCHs may include: the feedback information of all SPSPDSCHs in the first P time-domain resources associated with the first time-domain resource and the feedback information of some SPS PDSCHs in the (P+1)th time-domain resource; where P is an integer greater than or equal to 1.

[0105] In this embodiment of the application, the feedback information of a portion of SPS PDSCH determined from a time-domain resource can be the feedback information of the preceding portion of SPS PDSCH determined from the feedback information of all SPS PDSCH included in the time-domain resource. For example, the feedback information of the portion of SPS PDSCH can be the feedback information of the earlier time, and / or the feedback information of the earlier HARQ process number of the SPSPDSCH, and / or the feedback information of the earlier SPS configuration number, and / or the feedback information of the earlier carrier number of the carrier on which the SPSPDSCH is located.

[0106] Figure 7 This is a schematic diagram illustrating the implementation flow of another data transmission method provided in an embodiment of this application, as shown below. Figure 7 As shown, this method is applied to a terminal device, and the method includes:

[0107] S701. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling (SPS) physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0108] S702. Determine the feedback information of the first N SPS PDSCHs in the feedback information set, corresponding to the second target resource, and the second target resource is allowed to be transmitted in the first time domain resource.

[0109] In this step, the second target resource being allowed to be transmitted within the first time-domain resource may include: data on the second target resource (including feedback information of the first N SPS PDSCHs, for example, feedback information of a portion of the SPS PDSCHs in a time-domain resource associated with the first time-domain resource, or feedback information of all the SPS PDSCHs in the first P time-domain resources and feedback information of a portion of the SPS PDSCHs in the P+1th time-domain resource among multiple time-domain resources associated with the first time-domain resource) being allowed to be transmitted within the first time-domain resource, and / or, the second target resource being an uplink resource and / or a flexible resource. In this embodiment, the symbol used for the flexible resource is the flexible symbol.

[0110] S703. Determine that the feedback information of the first N+1 SPS PDSCHs corresponds to the third target resource, and the third target resource is not allowed to be transmitted in the first time domain resource; the number of bits that the third target resource can carry is greater than the number of bits that the second target resource can carry.

[0111] In some embodiments, the third target resource is not allowed to be transmitted in the first time domain resource, which may include: the number of bits of feedback information of the first N+1 SPS PDSCH is greater than the number of bits that the third target resource can carry; or, the third target resource includes unavailable resources.

[0112] For example, the feedback information of the first N+1 SPS PDSCHs is 3 bits, but the third target resource can only carry 2 bits, thus determining that the third target resource is not allowed to be transmitted in the first time domain resource.

[0113] S704. Determine the feedback information of the first N SPS PDSCH as the target feedback information.

[0114] S705, transmit target feedback information on the first time domain resource.

[0115] Still with Figure 4 For example, for Figure 7 The corresponding implementation example illustrates this: If only 1 bit of feedback information corresponding to SPSPDSCH 0 is transmitted in Slot n+3, PUCCH resource 1 is used. PUCCH resource 1 occupies all uplink symbols in the time domain, meaning PUCCH resource 1 is available. If only 2 bits of feedback information corresponding to SPS PDSCH 0 and SPS PDSCH 1 are transmitted in Slot n+3, PUCCH resource 1 is used. PUCCH resource 1 occupies all uplink symbols in the time domain, meaning PUCCH resource 1 is available. However, if 3 bits of feedback information corresponding to SPS PDSCH 0-2 are transmitted in Slot n+3, PUCCH resource 2 is required. But PUCCH resource 2 occupies downlink symbols in the time domain, meaning PUCCH resource 2 is unavailable. Therefore, the terminal device determines:

[0116] (1) The 2-bit feedback information corresponding to SPS PDSCH 0 and SPS PDSCH 1 is transmitted in Slot n+3;

[0117] (2) Feedback information from SPS PDSCH 2-5 is further postponed to Slot n+5.

[0118] The feedback information from SPS PDSCH in Slot n+5 can be based on Figure 7 The corresponding embodiments can be deduced by analogy, and the embodiments in this application will not be described in detail.

[0119] Figure 8 This is a schematic diagram illustrating the implementation flow of another data transmission method provided in an embodiment of this application, as shown below. Figure 8 As shown, this method is applied to a terminal device, and the method includes:

[0120] S801. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling (SPS) physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0121] S802. Determine a fourth target resource from one or more uplink resources; the number of bits that the fourth target resource can carry is the maximum number of bits that the one or more uplink resources can carry respectively; the one or more uplink resources are uplink resources available in the first time domain resources for transmitting feedback information.

[0122] In any embodiment of this application, the fourth target resource can be not only an uplink resource, but also a resource with the largest number of bits that can be carried, thereby enabling the transmission of as much SPS PDSCH feedback information as possible.

[0123] S803. Based on the number of bits that the fourth target resource can carry, determine the feedback information of all SPS PDSCH in the first P time domain resources of one or more time domain resources associated with the first time domain resource; one or more time domain resources are before the first time domain resource.

[0124] Among them, the number of bits that the fourth target resource can carry is greater than or equal to the number of bits of feedback information of all SPSPDSCH in the first P time-domain resources, and less than the number of bits of feedback information of all SPS PDSCH in the first P+1 time-domain resources.

[0125] S804. Determine the feedback information of all SPS PDSCH in the first P time-domain resources as the target feedback information.

[0126] S805, transmit target feedback information on the first time domain resource.

[0127] exist Figure 8 In the corresponding embodiment, the feedback information of the first N SPS PDSCHs is determined based on time-domain resources as the smallest unit, and the target feedback information is determined based on the number of bits that the fourth target resource that meets the requirements in the first time-domain resources can carry.

[0128] Figure 9 Another SPS HARQ-ACK feedback diagram provided for an embodiment of this application, as shown below. Figure 9As shown, the terminal device can be configured with two SPS configurations: SPS configuration 1 and SPS configuration 2. The pre-configured feedback time slot k1 is always one time slot. Additionally, the network device is configured with three PUCCH resources for transmitting SPS ACK / NACK, where PUCCH resource 1 is used to transmit 1 or 2 bits of information, and PUCCH resources 2 and 3 are used to transmit more than 2 bits of information. Uplink resources are configured in Slot n+3 and Slot n+5.

[0129] Feedback information for SPS PDSCH 0 and SPS PDSCH 1 in Slot n is transmitted in Slot n+1. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 2 and SPS PDSCH 3 in Slot n+1 is transmitted in Slot n+2. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 4 and SPS PDSCH 5 in Slot n+2 is transmitted in Slot n+3.

[0130] In Slot n+3, the available PUCCH resources are PUCCH 1 and PUCCH 2, where PUCCH 1 can carry 2 bits and PUCCH 2 can carry 5 bits.

[0131] In Adoption Figure 8 In the corresponding embodiment, both PUCCH1 and PUCCH2 are uplink resources. Therefore, based on PUCCH2, which has a larger number of bearer bits, the feedback information of all SPS PDSCHs in the first P time-domain resources can be determined. Then, the terminal device can determine:

[0132] (1) The 4-bit feedback information corresponding to SPS PDSCH 0-3 is transmitted in Slot n+3 via PUCCH2;

[0133] (2) Feedback information from SPS PDSCH 4-5 is further postponed to Slot n+5.

[0134] In Slot n+5, the available PUCCH resources are PUCCH1, PUCCH2, and PUCCH3. PUCCH1 can carry 2 bits, PUCCH2 can carry 5 bits, and PUCCH3 can carry 10 bits. The total number of HARQ-ACK bits required for Slot n+5 is 4 bits. Therefore, the terminal device determines:

[0135] The 5-bit feedback information corresponding to SPS PDSCH 4-8 is transmitted via PUCCH2 in Slot n+5.

[0136] Figure 10 A schematic diagram illustrating the implementation flow of a data transmission method provided in another embodiment of this application is shown below. Figure 10 As shown, this method is applied to a terminal device, and the method includes:

[0137] S1001. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling SPS physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0138] S1002. Determine a fourth target resource from one or more uplink resources; the number of bits that the fourth target resource can carry is the maximum number of bits that the one or more uplink resources can carry; the one or more uplink resources are uplink resources available in the first time domain resources for transmitting feedback information.

[0139] S1003. Based on the number of bits that the fourth target resource can carry, determine the feedback information of the first N SPS PDSCHs; the number of bits that the fourth target resource can carry is greater than or equal to the feedback information of the first N SPS PDSCHs, and less than or equal to the feedback information of the first N+1 SPS PDSCHs.

[0140] S1004. Determine the feedback information of the first N SPS PDSCH as the target feedback information.

[0141] S1005. Transmit target feedback information on the first time domain resource.

[0142] exist Figure 10 In the corresponding embodiment, the feedback information of the first N SPS PDSCHs is determined based on the HARQ-ACK bit corresponding to a PDSCH as the smallest unit, and the target feedback information is determined based on the number of bits that the fourth target resource that meets the requirements in the first time domain resource can carry.

[0143] Continue reading Figure 9 In adopting Figure 10 In the case of the corresponding embodiment, the terminal device can determine:

[0144] (1) The 5-bit feedback information corresponding to SPS PDSCH 0-4 is transmitted in Slot n+3 via PUCCH2;

[0145] (2) Feedback information from SPS PDSCH 5 is further delayed until Slot n+5.

[0146] Therefore, it was determined that the 4-bit feedback information corresponding to SPS PDSCH5-8 was transmitted through PUCCH2 in Slot n+5.

[0147] exist Figure 8 and Figure 10 Both methods determine the target feedback information based on the number of bits that the fourth target resource, which meets the requirements, can carry in the first time domain resource. In this approach, delaying the transmission of SPS ACK / NACK will not cause out-of-order delivery, thus breaking the... Figure 3 The corresponding timing constraints make implementation simple on terminal devices. Compared to... Figure 6 and Figure 7 In the corresponding implementation, unnecessary SPS ACK / NACK delays can be avoided when PUCCH resources are available under heavy load but unavailable under light load. This is because Implementation 1 determines PUCCH resources and HARQ-ACK bits by sorting them from smallest to largest load, and stops processing once an unavailable resource is encountered. Figure 8 and Figure 10 The corresponding implementation is to select available and high-load PUCCH resources as much as possible to ensure that SPS ACK / NACK can be transmitted as much as possible.

[0148] To avoid HARQ-ACK codebook reassembly, this application embodiment can also provide a data transmission method. In the method provided by this embodiment, the feedback information of M SPS PDSCHs includes: the feedback information of all SPS PDSCHs in one or more time-domain resources before the first time-domain resource;

[0149] The target feedback information includes: the delayed first feedback information associated with the first time domain resource;

[0150] The first feedback information includes: specified feedback information transmitted on the second time domain resource based on the time domain offset; the second time domain resource is prior to the first time domain resource, and there is no available resource in the second time domain resource for transmitting the specified feedback information.

[0151] Figure 11 A schematic diagram illustrating the implementation flow of a data transmission method provided in another embodiment of this application is shown below. Figure 11 As shown, this method is applied to a terminal device, and the method includes:

[0152] S1101. Obtain the set of feedback information associated with the first time domain resource; the set of feedback information includes: feedback information of M semi-persistent scheduling SPS physical downlink shared channels (PDSCH); M is an integer greater than or equal to 1.

[0153] S1102. Determine the target feedback information from the set of feedback information; the target feedback information includes: the feedback information of the first N SPS PDSCHs out of the feedback information of M SPS PDSCHs; N is an integer greater than or equal to 1 and less than or equal to M.

[0154] S1103. If a fifth target resource exists in one or more uplink resources, first feedback information is transmitted on the fifth target resource; the number of bits that the fifth target resource can carry is greater than or equal to the number of bits of the first feedback information, and is the number of bits that is closest to the number of bits of the first feedback information among the number of bits that the one or more uplink resources can carry respectively; the one or more uplink resources are uplink resources available in the first time domain for transmitting feedback information.

[0155] In some embodiments, the target feedback information further includes: undelayed second feedback information associated with the first time-domain resource; the second feedback information includes: feedback information transmitted on the first time-domain resource based on the time-domain offset;

[0156] The data transmission method may further include: transmitting the first feedback information and the second feedback information on the fifth target resource when the number of bits that the fifth target resource can carry is greater than or equal to the sum of the number of bits of the first feedback information and the number of bits of the second feedback information.

[0157] In some instances, the data transmission method may further include: determining a sixth target resource from one or more uplink resources if the number of bits that the fifth target resource can carry is less than the sum of the number of bits of the first feedback information and the number of bits of the second feedback information; the number of bits that the sixth target resource can carry is greater than or equal to the sum of the number of bits of the first feedback information and the number of bits of the second feedback information; and transmitting the first feedback information and the second feedback information on the sixth target resource.

[0158] The second feedback information includes: feedback information transmitted on the first time domain resource based on the time domain offset.

[0159] In other embodiments, if the number of bits that the fifth target resource can carry is less than the sum of the number of bits of the first feedback information and the number of bits of the second feedback information, and there is no sixth target resource in one or more uplink resources, the second feedback information is transmitted on a time domain resource after the first time domain resource.

[0160] In some instances, the data transmission method may also include transmitting first feedback information on a time domain resource following the first time domain resource, in the case that a fifth target resource is not present in one or more uplink resources.

[0161] In some implementations, the time-domain resource following the first time-domain resource can be a third time-domain resource, which can be one or more time-domain resources. The third time-domain resource can be adjacent to the first time-domain resource, or it can be separated from the first time-domain resource by at least one time-domain resource. The third time-domain resource can be determined based on a time-domain offset and the SPS PDSCH in the first time-domain resource or the SPS PDSCH in a resource before or after the first time-domain resource. For example, if the first time-domain resource contains an SPS PDSCH, the third time-domain resource is determined based on the position and time-domain offset of the SPS PDSCH in the first time-domain resource.

[0162] Transmitting first feedback information on a time domain resource following the first time domain resource may include: determining a delayed third feedback information associated with a third time domain resource; the third feedback information includes the first feedback information; determining a fifth target resource from multiple uplink resources in the third time domain resource used for transmitting feedback information to be transmitted, wherein the number of bits that the fifth target resource can carry is greater than or equal to the number of bits that the third feedback information can carry, and is the number of bits that the multiple uplink resources can carry that is closest to the number of bits that the third feedback information can carry; and transmitting the third feedback information based on the fifth target resource.

[0163] Figure 12 Another SPS HARQ-ACK feedback diagram provided for embodiments of this application, such as... Figure 12 As shown, the terminal device can be configured with two SPS configurations, namely SPS configuration 1 and SPS configuration 2, with a pre-configured feedback time slot k1 of only one time slot. Additionally, the network device is configured with three PUCCH resources for transmitting SPS ACK / NACK, where PUCCH resource 1 is used to transmit 1 or 2 bits of information, and PUCCH resources 2 and 3 are used to transmit more than 2 bits of information. Uplink resources are configured in Slot n+3, Slot n+5, and Slot n+6.

[0164] Feedback information for SPS PDSCH 0 and SPS PDSCH 1 in Slot n is transmitted in Slot n+1. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 2 and SPS PDSCH 3 in Slot n+1 is transmitted in Slot n+2. However, this Slot is a downlink time slot and cannot transmit feedback information, so the corresponding feedback information needs to be delayed. Feedback information for SPS PDSCH 4 and SPS PDSCH 5 in Slot n+2 is transmitted in Slot n+3.

[0165] If the 4-bit feedback information corresponding to SPS PDSCH 0-3 (delayed) is to be transmitted in Slot n+3, PUCCH resource 2 is required. However, the time-domain symbols occupied by PUCCH resource 2 include downlink symbols, meaning PUCCH resource 2 is unavailable. Therefore, the terminal device determines:

[0166] Feedback information from SPS PDSCH 0-5 continues to be delayed until Slot n+5.

[0167] If only the 7-bit feedback information corresponding to SPS PDSCH 0-6 (delayed) is transmitted in Slot n+5, PUCCH resource 2 is used. The time-domain symbols occupied by PUCCH resource 2 are all uplink symbols, meaning PUCCH resource 2 is available. If the 9-bit feedback information corresponding to SPS PDSCH 0-8 is transmitted in Slot n+5, PUCCH resource 3 is used. The time-domain symbols occupied by PUCCH resource 3 are downlink symbols, meaning PUCCH resource 3 is unavailable. Then the terminal device determines:

[0168] (1) The 7-bit feedback information corresponding to SPS PDSCH 0-6 is transmitted in Slot n+5;

[0169] (2) Feedback information from SPS PDSCH 7-8 is further postponed to Slot n+6.

[0170] If only the 2-bit feedback information corresponding to SPS PDSCH 7-8 is transmitted in Slot n+6, using PUCCH resource 1, and the time domain symbols occupied by PUCCH resource 1 are all uplink symbols, i.e., PUCCH resource 1 is available; then the terminal device determines:

[0171] The 2-bit feedback information corresponding to SPS PDSCH 7-8 is transmitted in Slot n+6.

[0172] This embodiment determines the transmission of HARQ-ACK bits using time slots as the smallest unit. It can also be extended to use HARQ-ACK bits corresponding to one PDSCH as the smallest unit.

[0173] In this embodiment, the transmission of SPS ACK / NACK follows the principle of prioritizing early transmission based on time sequence, thus avoiding out-of-order transmission and breaking the rule. Figure 3 The corresponding timing constraints simplify implementation on terminal devices. It does not introduce additional SPSACK / NACK feedback latency. Compared to... Figures 6 to 8 and Figure 10 The embodiment is divided into two parts: delayed and non-delayed. The delayed SPS PDSCH feedback information is transmitted on a time-domain resource, avoiding HARQ-ACK codebook reassembly.

[0174] The UE handles out-of-order issues differently for PDSCHs of different types. Since network devices have complete control over dynamically scheduled transmissions, out-of-order transmissions can be avoided through network device scheduling. However, for SPS PDSCHs, network devices cannot prevent out-of-order transmissions through scheduling. The data transmission method provided in this application's embodiments can prevent out-of-order feedback information from occurring in SPS PDSCHs.

[0175] This section describes the method performed by the network device during data transmission. In the implementation process, the network device can perform corresponding calculation processes with the terminal device to confirm that it can receive the target feedback information in the first time domain resource, and then receive the target feedback information on the first time domain resource. Based on the target feedback information, it can be determined that the terminal device has received the first N SPS PDSCH.

[0176] Figure 13 This is a schematic diagram illustrating the implementation flow of a data transmission method provided in another embodiment of this application, as shown below. Figure 13 As shown, this method is applied to a network device, and the method includes:

[0185] The second feedback information includes: feedback information transmitted on the first time domain resource based on the time domain offset.

[0186] In some embodiments, the first target resource in the first time domain resource used for transmitting target feedback information is a resource corresponding to the target number of bits; the target number of bits belongs to the number of bits that one or more uplink resources can carry respectively, the target number of bits is closest to the number of bits in the feedback information set, and the target number of bits is greater than or equal to the number of bits in the feedback information set; the one or more uplink resources are uplink resources available in the first time domain resource for transmitting feedback information;

[0187] or,

[0188] The first target resource used for transmitting target feedback information in the first time domain resource is the resource corresponding to the largest number of bits among the number of bits that one or more available uplink resources can carry, and the number of bits that the first target resource can carry is less than or equal to the number of bits of the feedback information set.
