Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a feedback method, apparatus, device, and storage medium for semi-persistent scheduling. Background Art

[0002] The NR (New Radio) system supports multiple SPS (Semi-Persistent Schedule) configurations. For each SPS configuration, the terminal device must send a HARQ-ACK (Hybrid Automatic Repeat request-Acknowledge character) to the network device for data transmitted on the SPS PDSCH (Semi-Persistent Schedule Physical Downlink Shared Channel).

[0003] However, although the network device has configured multiple SPS configurations for the terminal device, the network device does not necessarily transmit data on all SPS PDSCHs corresponding to all SPS configurations. In related technologies, in order to adapt to fluctuations in data arrival, the network device often configures multiple SPS configurations for the terminal device to adapt to data arriving at any time. In fact, during a downlink data transmission cycle, only the SPS PDSCH corresponding to one of the multiple SPS configurations will carry data. That is, during the downlink data transmission cycle, the terminal device only feeds back HARQ-ACK to the network device for the data transmitted on one SPS PDSCH. The other SPS PDSCHs do not actually carry data, so their corresponding HARQ-ACK feedback is meaningless to the network device. One way to optimize HARQ-ACK feedback is to feed back HARQ-ACK according to the SPS group. That is, multiple SPS configurations for the same service form an SPS group. The HARQ-ACK feedback is for the overall data reception status of an SPS group, thereby avoiding the terminal device feeding back redundant and invalid HARQ-ACK to the network device.

[0004] However, even if multiple SPS configurations belong to the same SPS group, the HARQ-ACK feedback corresponding to the multiple SPS configurations can be mapped in different time slots, so that the terminal device needs to feed back the HARQ-ACK to the network device in different time slots for the SPS PDSCH corresponding to the multiple SPS configurations in the same SPS group. In this way, the power consumption of the terminal device will be adversely affected, and the processing overhead of the terminal device will be wasted. SUMMARY

[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0049] First, some terms involved in the embodiments of this application are introduced and explained.

[0050] 1. HARQ (Hybrid Automatic Repeat Request)

[0051] HARQ is a technology that combines Forward Error Correction (FEC) and Automatic Repeat-reQuest (ARQ). FEC is used at the receiving end to correct the portion of all errors that can be corrected. Error detection identifies packets that cannot be corrected. Uncorrectable packets are discarded, and the sender is requested to resend the same packet.

[0052] 2. SPS configuration

[0053] SPS configuration is also known as semi-persistent scheduling. Unlike dynamic scheduling, which allocates radio resources to terminal devices once per TTI (transmission time interval) (specified by the PDCCH (Physical Uplink Control Channel)), SPS configuration allows semi-static configuration of radio resources and periodic allocation of these resources to a specific terminal device.

[0054] For example, the network device uses the SPS C-RNTI (Cell-Radio Network Temporary Identifier, cell radio network temporary identifier) ​​scrambled PDCCH to specify the SPS PDSCH used by the terminal device in a certain TTI, and the terminal device uses the SPS PDSCH to receive or send data every cycle. The network device does not need to send PDCCH in this subframe (here referred to as the SPS subframe) to specify the allocated resources. Since the SPS configuration has the characteristics of "one configuration, multiple uses", there is no need to send DCI (Downlink Control Information, downlink control information) (including uplink or downlink DCI) to the terminal device in each TTI, thereby reducing the corresponding PDCCH overhead.

[0055] Please refer to Figure 1 , which shows a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture may include: a terminal device 10 and a network device 20.

[0056] There are usually multiple terminal devices 10, and one or more terminal devices 10 can be distributed in each cell managed by each network device 20. The terminal devices 10 can include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminal devices.

[0057] The network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in the 5G (5th-Generation, fifth-generation mobile communication technology) NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name of "network device" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices. Optionally, the network device 20 and the terminal device 10 communicate with each other through some air interface technology, such as the Uu interface.

[0058] In an example, the network device 20 may configure multiple SPS configurations for the terminal device 10 and transmit data to the terminal device 10 via the SPS PDSCH corresponding to the SPS configuration. The terminal device 10 feeds back HARQ-ACK to the network device 20 based on the data reception status.

[0059] The “5G NR system” in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art may understand its meaning.

[0060] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, NR system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to Unlicensed spectrum, LTE-U) system, NR-U (New Radio–Unlicensed, NR on unlicensed spectrum) system, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication system or other communication systems, etc.

[0061] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but also other types of communications, such as device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-everything (V2X) systems. The embodiments of the present application can also be applied to these communication systems.

[0062] In one example, the NR system supports multiple SPS configurations. For each SPS configuration corresponding to the SPS PDSCH data transmitted, the terminal device needs to feedback HARQ-ACK to the network device.

[0063] However, although the network device has configured multiple SPS configurations for the terminal device, the network device does not necessarily transmit data on all SPS PDSCHs corresponding to all SPS configurations. In related technologies, in order to adapt to fluctuations in data arrival, network devices often configure multiple SPS configurations for terminal devices to adapt to data arriving at any time. In fact, during a downlink data transmission cycle, only one SPS PDSCH corresponding to a multiple SPS configuration will carry data. That is, during the downlink data transmission cycle, the terminal device only feeds back HARQ-ACK to the network device for the data transmitted on one SPS PDSCH. Other SPS PDSCHs do not actually carry data, so their corresponding HARQ-ACK feedback is meaningless to the network device.

[0064] For example, Figure 2 As shown in the figure, for a service with a transmission period of 4 time slots and a data arrival fluctuation range of 0-12 time slots, the network device configures 7 SPS configurations for the terminal device: SPS configuration 1, SPS configuration 2, SPS configuration 3, SPS configuration 4, SPS configuration 5, SPS configuration 6, and SPS configuration 7. The starting time slots of the SPS PDSCH corresponding to these 7 SPS configurations are offset by {0, 2, 4, 6, 8, 10, 12} time slots respectively, and the period of each SPS configuration is 4 time slots. Therefore, in fact, within the same period, only one of the 7 SPS configurations will carry data. For example, Figure 2 As shown in (1), the SPS PDSCH corresponding to SPS configuration 1 carries data, and the SPS PDSCHs corresponding to the other 6 SPS configurations do not carry data. The terminal device then feeds back HARQ-ACK to the network device: A, N, N, N, N, N, N (1, 0, 0, 0, 0, 0); wherein A represents ACK (Acknowledge), which indicates that the terminal device has received data on the SPS PDSCH corresponding to SPS configuration 1; and N represents NACK (Non-Acknowledge), which indicates that the terminal device has not received data on the SPS PDSCHs corresponding to SPS configurations 2 to 7. For another example, Figure 2 As shown in (2), the SPS PDSCH corresponding to SPS configuration 4 carries data, and the SPS PDSCH corresponding to the other 6 SPS configurations do not carry data. The terminal device then feeds back HARQ-ACK to the network device: N,N,N,A,N,N,N(0,0,0,1,0,0,0). Figure 2As can be seen from the example shown, only one SPS PDSCH actually requires the terminal device to feedback HARQ-ACK, and the HARQ-ACKs corresponding to other SPS PDSCHs are meaningless to the network device.

[0065] In one example, the way to optimize HARQ-ACK feedback is to feedback HARQ-ACK according to the SPS group (in the embodiment of the present application, "SPS group" is also referred to as "HARQ-ACK group"), that is, multiple SPS configurations for the same service form a HARQ-ACK group, and the HARQ-ACK feedback is for the overall data reception status of a HARQ-ACK group, thereby avoiding the terminal device from feeding back redundant and invalid HARQ-ACK to the network device.

[0066] For example, Figure 3 As shown in FIG, the network device classifies the seven SPS configurations into the same HARQ-ACK group, and the SPS configurations included in the HARQ-ACK group correspond to the same HARQ-ACK feedback time unit 30. Therefore, the terminal device feeds back HARQ-ACK to the network device based on the data reception status on the SPS PDSCH corresponding to the seven SPS configurations through the HARQ-ACK feedback time unit 30. Figure 3 As shown in (1), the SPS PDSCH corresponding to SPS configuration 7 carries data. If the terminal device correctly receives data on the SPS PDSCH corresponding to SPS configuration 7, the terminal device feeds back HARQ-ACK: ACK to the network device. Figure 3 As shown in (2), the SPS PDSCH corresponding to SPS configuration 4 carries data. If the terminal device correctly receives data on the SPS PDSCH corresponding to SPS configuration 4, the terminal device feeds back HARQ-ACK: ACK to the network device.

[0067] However, even if multiple SPS configurations belong to the same SPS group, the HARQ-ACK feedback corresponding to the multiple SPS configurations may be mapped to different feedback time units. Therefore, the terminal device needs to feedback HARQ-ACK to the network device in different feedback time units for the SPS PDSCH corresponding to multiple SPS configurations in the same SPS group.

[0068] For example, Figure 4As shown, the network device groups the seven SPS configurations into the same HARQ-ACK group, and the SPS configurations in the group correspond to four HARQ-ACK feedback time units: the first HARQ-ACK feedback time unit 410, the second HARQ-ACK feedback time unit 420, the third HARQ-ACK feedback time unit 430, and the fourth HARQ-ACK feedback time unit 440. SPS configurations 1 and 2 correspond to the first HARQ-ACK feedback time unit 410; SPS configurations 3 and 4 correspond to the second HARQ-ACK feedback time unit 420; SPS configurations 5 and 6 correspond to the third HARQ-ACK feedback time unit 430; and SPS configuration 7 corresponds to the fourth HARQ-ACK feedback time unit 440. The terminal device uses these four HARQ-ACK feedback time units to provide the network device with feedback on the data reception status of the SPS PDSCH corresponding to the seven SPS configurations.

[0069] like Figure 4 As shown in (1), the SPS PDSCH corresponding to SPS configuration 7 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 7. Since the terminal device does not correctly receive data in the SPS PDSCH corresponding to the first 6 SPS configurations (the SPS PDSCH corresponding to the first 6 SPS configurations does not carry data), the terminal device feeds back HARQ-ACK: NACK to the network device in the first HARQ-ACK feedback time unit 410, the second HARQ-ACK feedback time unit 420 and the third HARQ-ACK feedback time unit 430 respectively; and feeds back HARQ-ACK: ACK to the network device in the fourth HARQ-ACK feedback time unit 440. As shown in Figure 4 As shown in (2), the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 4. Since the terminal device does not correctly receive data in the SPS PDSCH corresponding to the other 6 SPS configurations (the SPS PDSCH corresponding to the other 6 SPS configurations does not carry data), the terminal device feeds back HARQ-ACK: NACK to the network device in the first HARQ-ACK feedback time unit 410, the third HARQ-ACK feedback time unit 430, and the fourth HARQ-ACK feedback time unit 440, and feeds back HARQ-ACK: ACK to the network device in the second HARQ-ACK feedback time unit 420.

[0070] based on Figure 4As can be seen from the example shown, the terminal device may need to feedback HARQ-ACK to the network device in different feedback time units for the SPS PDSCHs corresponding to multiple SPS configurations in the same SPS group. This will not be conducive to reducing the power consumption of the terminal device and will cause waste in the processing overhead of the terminal device. Based on this, an embodiment of the present application provides a feedback method for semi-permanent scheduling, which can be used to reduce the processing overhead and power consumption of the terminal device. Below, the technical solution of the present application is introduced and explained in conjunction with several embodiments.

[0071] Please refer to Figure 5 , which shows a flow chart of a feedback method for semi-permanent scheduling provided by an embodiment of the present application. Figure 1 In the system architecture shown in Figure 5 As shown, the method includes at least one or more of the following steps.

[0072] In step 510, the network device sends an SPS activation instruction to the terminal device. The SPS activation instruction is used to activate a first SPS configuration, and the first SPS configuration corresponds to a first HARQ-ACK packet.

[0073] The network device sends one or more SPS activation instructions to the terminal device, and the terminal device activates the corresponding SPS configuration according to each SPS activation instruction. For ease of description, in the embodiments of the present application, an example of a network device sending an SPS activation instruction to a terminal device is used for description, but this does not constitute a limitation of the present application.

[0074] Taking the example of a network device sending an SPS activation instruction to a terminal device, optionally, the SPS activation instruction is carried in a DCI. In an embodiment of the present application, the SPS activation instruction is used to activate a first SPS configuration. The first SPS configuration can be a single SPS configuration, but the embodiment of the present application does not exclude the possibility that the first SPS configuration can be multiple SPS configurations.

[0075] Optionally, one SPS configuration corresponds to one HARQ-ACK group, and one HARQ-ACK group includes at least one SPS configuration. In this embodiment of the present application, the first SPS configuration corresponds to the first HARQ-ACK group, and the first HARQ-ACK group includes at least one SPS configuration, that is, in addition to the first SPS configuration, the first HARQ-ACK group may also include other SPS configurations.

[0076] In one example, the first SPS configuration activated by the SPS activation instruction is the first SPS configuration among one or more SPS configurations configured in advance by the network device for the terminal device. Figure 6As shown, before the above step 510, step 500 is also included: the network device sends SPS configuration information to the terminal device, and the SPS configuration information is used to configure the first SPS configuration. The network device can send one or more SPS configuration information to the terminal device. For the convenience of description, in the embodiment of the present application, the network device sends an SPS configuration information to the terminal device as an example for introduction and explanation. It should be understood that this does not constitute a limitation of the present application. Taking the network device sending an SPS configuration information to the terminal device as an example, the SPS configuration information is used to configure the first SPS configuration, but the embodiment of the present application does not exclude the possibility that the SPS configuration information also configures other SPS configurations at the same time. The embodiment of the present application does not limit the specific configuration parameters included in the SPS configuration information. Optionally, the SPS configuration information includes at least one of the following configuration parameters: SPS configuration index, HARQ-ACK group corresponding to the SPS configuration, period of the SPS configuration, number of repetitions of the SPS configuration, and resource location of the SPS configuration.

[0077] Taking the example of a network device configuring multiple SPS configurations for a terminal device in advance, optionally, the multiple SPS configurations can correspond to (or be referred to as "belong to") the same HARQ-ACK group, or can correspond to multiple different HARQ-ACK groups. For example, the network device has configured 7 SPS configurations for the terminal device in advance, and these 7 SPS configurations correspond to the same HARQ-ACK group. For another example, the network device has configured 7 SPS configurations for the terminal device in advance, and SPS configuration 1, SPS configuration 2, and SPS configuration 3 of these 7 SPS configurations correspond to one HARQ-ACK group, and SPS configuration 4, SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to another HARQ-ACK group.

[0078] In step 520 , the terminal device feeds back HARQ-ACK to the network device based on the first HARQ-ACK feedback time unit for the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet.

[0079] In one example, after activating the first SPS configuration through an SPS activation instruction, the network device may send data to the terminal device on the SPS PDSCH corresponding to the first SPS configuration. Figure 6As shown, after step 510, the method further includes step 530: the network device transmits data to the terminal device on the SPS PDSCH corresponding to the first SPS configuration. Since the network device may activate other SPS configurations in the embodiments of the present application, the network device may also transmit data to the terminal device on the SPS PDSCH corresponding to the other SPS configurations. In the case where the network device activates multiple SPS configurations, the network device may also transmit data to the terminal device on the SPS PDSCH corresponding to part of the multiple SPS configurations, that is, there may be no data actually carried on the SPS PDSCH corresponding to part of the multiple SPS configurations. Alternatively, in the same data transmission period, the network device transmits data to the terminal device only on the SPS PDSCH corresponding to one SPS configuration.

[0080] After the network device transmits data to the terminal device, the terminal device needs to feed back HARQ-ACK to the network device for data reception. Alternatively, the terminal device feeds back HARQ-ACK to the network device in groups, which can avoid feeding back redundant and invalid HARQ-ACK. Based on this, in the embodiments of the present application, the terminal device feeds back HARQ-ACK to the network device for the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK group, that is, for the data reception corresponding to the first HARQ-ACK group.

[0081] In one example, in the case where the first HARQ-ACK group includes multiple SPS configurations, the HARQ-ACK feedback time units corresponding to the multiple SPS configurations may be mapped at different time domain positions. In the embodiments of the present application, whether the HARQ-ACK feedback time units corresponding to the SPS configurations included in the first HARQ-ACK group are mapped at different time domain positions or not, the terminal device feeds back HARQ-ACK to the network device based on the first HARQ-ACK feedback time unit. Alternatively, the HARQ-ACK fed back by the terminal device to the network device based on the first HARQ-ACK feedback time unit is feedback for the overall data reception of the first HARQ-ACK group, but this does not constitute a limitation on the embodiments of the present application, for example, the HARQ-ACK fed back by the terminal device to the network device based on the first HARQ-ACK feedback time unit may also be feedback for the data reception corresponding to one SPS configuration in the first HARQ-ACK group.

[0082] Optionally, in an embodiment of the present application, the first HARQ-ACK packet corresponds to a 1-bit feedback information bit, so that the terminal device can feedback ACK or NACK to the network device. Exemplarily, when the terminal device feedbacks 1 to the network device, it indicates that the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet is correctly received; when the terminal device feedbacks 0 to the network device, it indicates that the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK packet is not correctly received.

[0083] The embodiment of the present application does not limit the form of expression of the first HARQ-ACK feedback time unit. Optionally, the first HARQ-ACK feedback time unit includes any of the following time units: time slot, sub-time slot, symbol, frame, subframe. The embodiment of the present application does not limit the specific method for determining the first HARQ-ACK feedback time unit. Optionally, the SPS activation instruction includes HARQ-ACK timing information corresponding to the first SPS configuration, and the HARQ-ACK timing information corresponding to the first SPS configuration is used to indicate the first HARQ-ACK feedback time unit. Based on this, the above method also includes: the terminal device determines the first HARQ-ACK feedback time unit based on the HARQ-ACK timing information corresponding to the first SPS configuration and the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration. Exemplarily, the terminal device offsets the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration according to the HARQ-ACK timing information corresponding to the first SPS configuration to obtain the first HARQ-ACK feedback time unit. For example, the HARQ-ACK timing information corresponding to the first SPS configuration is 4 time slots, and the data transmission time unit of the SPS PDSCH corresponding to the first SPS configuration is time slot 3. Then, the first HARQ-ACK feedback time unit is time slot 7.

[0084] For other descriptions of the first HARQ-ACK feedback time unit and the first SPS configuration, please refer to the following method embodiment, which will not be repeated here.

[0085] To sum up, the technical solution provided in the embodiment of the present application, through the terminal device's feedback of the data reception status of the SPS PDSCH corresponding to the SPS configuration included in a HARQ-ACK group, to the network device based on a HARQ-ACK feedback time unit, realizes the feedback of the data reception status of the SPS PDSCH corresponding to the SPS configuration belonging to the same HARQ-ACK group to the network device in one HARQ-ACK feedback time unit, avoids the need for the terminal device to feedback HARQ-ACK to the network device for the same HARQ-ACK group in different HARQ-ACK feedback time units, helps to reduce the power consumption and processing overhead of the terminal device, and also improves the reliability and efficiency of uplink transmission.

[0086] In the embodiment of the present application, in order to enable the terminal device to feedback HARQ-ACK to the network device within one HARQ-ACK feedback time unit for the same HARQ-ACK packet, multiple methods for determining the first HARQ-ACK feedback time unit are provided. These multiple methods are described below.

[0087] First, the first method is introduced: the HARQ-ACK feedback time units corresponding to the SPS configurations belonging to the same HARQ-ACK group are aligned.

[0088] In one example, the HARQ-ACK timing information corresponding to the SPS configuration included in the first HARQ-ACK group is used to indicate the first HARQ-ACK feedback time unit.

[0089] That is, the first HARQ-ACK group includes the HARQ-ACK timing information corresponding to each SPS configuration, ensuring that the HARQ-ACK feedback time unit corresponding to each SPS configuration is the same HARQ-ACK feedback time unit, that is, the first HARQ-ACK feedback time unit, thereby achieving alignment of the HARQ-ACK feedback time units corresponding to each SPS configuration belonging to the same HARQ-ACK group.

[0090] For example, Figure 7 As shown, the network device divides the 7 SPS configurations into the same HARQ-ACK group, wherein the HARQ-ACK feedback time unit corresponding to each SPS configuration is a HARQ-ACK feedback time unit 710. Figure 7As shown, the starting time slots of the SPS PDSCH corresponding to the seven SPS configurations are offset by {0, 1, 2, 3, 4, 5, 6} time slots, and the period of each SPS configuration is 10 time slots. In order to ensure that the seven SPS configurations correspond to the same HARQ-ACK feedback time unit 710, the HARQ-ACK timing information corresponding to the seven SPS configurations needs to be configured as {7, 6, 5, 4, 3, 2, 1} time slots respectively.

[0091] Next, a second method is described: using the SPS configuration corresponding to the SPS PDSCH that correctly receives data in a HARQ-ACK packet as a basis for determining the HARQ-ACK feedback time unit corresponding to the HARQ-ACK packet.

[0092] In one example, the first SPS configuration refers to the SPS configuration included in the first HARQ-ACK packet, and the SPS configuration corresponding to the SPS PDSCH on which the terminal device correctly receives data.

[0093] That is, the terminal device uses the SPS configuration corresponding to the SPSPDSCH that correctly receives data in the SPS configuration included in a HARQ-ACK group, and the corresponding HARQ-ACK feedback time unit as the HARQ-ACK feedback time unit for the data reception status of the HARQ-ACK group. Since in this example, the terminal device correctly receives data on the SPSPDSCH corresponding to the first SPS configuration, the HARQ-ACK includes ACK; the above step 520 includes: the terminal device feeds back ACK to the network device based on the first HARQ-ACK feedback time unit for the data transmitted on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK group. For the SPS configuration corresponding to the SPS PDSCH that did not correctly receive data in the SPS configuration included in the first HARQ-ACK group, the terminal device does not feed back HARQ-ACK to the network device.

[0094] For example, Figure 8As shown, the network device groups the seven SPS configurations into the same HARQ-ACK group, and the SPS configurations in the group correspond to four HARQ-ACK feedback time units: the first HARQ-ACK feedback time unit 810, the second HARQ-ACK feedback time unit 820, the third HARQ-ACK feedback time unit 830, and the fourth HARQ-ACK feedback time unit 840. Among them, SPS configuration 1 and SPS configuration 2 correspond to the first HARQ-ACK feedback time unit 810; SPS configuration 3 and SPS configuration 4 correspond to the second HARQ-ACK feedback time unit 820; SPS configuration 5 and SPS configuration 6 correspond to the third HARQ-ACK feedback time unit 830; and SPS configuration 7 corresponds to the fourth HARQ-ACK feedback time unit 840.

[0095] like Figure 8 As shown in FIG, the starting time slots of the SPS PDSCH corresponding to the 7 SPS configurations are offset by {0, 1, 2, 3, 4, 5, 6} time slots respectively, and the HARQ-ACK timing information corresponding to the 7 SPS configurations is configured as {2, 1, 2, 1, 2, 1, 1} time slots respectively, and the period of each SPS configuration is 10 time slots. Figure 8 As shown in (1), for the first data transmission cycle, the SPS PDSCH corresponding to SPS configuration 7 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 7, then the terminal device feeds back HARQ-ACK to the network device in the 4th HARQ-ACK feedback time unit 840 (time slot 7) corresponding to SPS configuration 7. Figure 8 As shown in (2), for the second data transmission cycle, the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 4, then the terminal device feeds back HARQ-ACK to the network device in the second HARQ-ACK feedback time unit 820 (time slot 14) corresponding to SPS configuration 4.

[0096] Secondly, the third method is introduced: using the SPS configuration that meets certain conditions in a HARQ-ACK group as the basis for determining the HARQ-ACK feedback time unit corresponding to the HARQ-ACK group.

[0097] In one example, the first SPS configuration refers to an SPS configuration that satisfies the first condition among the SPS configurations included in the first HARQ-ACK group.

[0098] That is, the terminal device uses the HARQ-ACK feedback time unit corresponding to the SPS configuration that meets the first condition in the SPS configuration included in a HARQ-ACK group as the HARQ-ACK feedback time unit for the data reception situation of the HARQ-ACK group. The embodiment of the present application does not limit the specific content of the first condition. Optionally, the first condition includes any one of the following: the data transmission unit of the SPS PDSCH in the SPS configuration included in the first HARQ-ACK group is located last, the SPS configuration index in the SPS configuration included in the first HARQ-ACK group is the smallest, the SPS configuration index in the SPS configuration included in the first HARQ-ACK group is the largest, and the SPS configuration included in the first HARQ-ACK group is configured to be used to determine the first HARQ-ACK feedback time unit.

[0099] In this example, regardless of whether the terminal device receives the data correctly, it is necessary to feedback HARQ-ACK to the network device. Based on this, optionally, HARQ-ACK includes ACK or NACK; the above step 520 includes: the terminal device is on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK group, and if the terminal device correctly receives the data, the terminal device feedbacks ACK to the network device based on the first HARQ-ACK feedback time unit; the terminal device is on the SPS PDSCH corresponding to the SPS configuration included in the first HARQ-ACK group, and if the terminal device does not correctly receive the data, the terminal device feedbacks NACK to the network device based on the first HARQ-ACK feedback time unit. That is, only when the terminal device fails to correctly receive data on the SPS PDSCH corresponding to all the SPS configurations included in the first HARQ-ACK group, the terminal device feedbacks NACK to the network device, and in all other cases, the terminal device feedbacks ACK to the network device. It should be understood that this does not constitute a limitation of the present application. For example, the terminal device may also feedback to the network device the reception status of the data transmitted on the SPS PDSCH corresponding to a specific SPS configuration in the first HARQ-ACK group. When the data transmitted on the SPS PDSCH corresponding to the SPS configuration is correctly received, the terminal device feedbacks ACK to the network device; when the data transmitted on the SPS PDSCH corresponding to the SPS configuration is not correctly received, the terminal device feedbacks NACK to the network device.

[0100] For example, Figure 9As shown, the network device groups seven SPS configurations into the same HARQ-ACK group, and the SPS configurations in the group correspond to four HARQ-ACK feedback time units: a first HARQ-ACK feedback time unit 910, a second HARQ-ACK feedback time unit 920, a third HARQ-ACK feedback time unit 930, and a fourth HARQ-ACK feedback time unit 940. SPS configuration 1 and SPS configuration 2 correspond to the first HARQ-ACK feedback time unit 910; SPS configuration 3 and SPS configuration 4 correspond to the second HARQ-ACK feedback time unit 920; SPS configuration 5 and SPS configuration 6 correspond to the third HARQ-ACK feedback time unit 930; and SPS configuration 7 corresponds to the fourth HARQ-ACK feedback time unit 940.

[0101] like Figure 9 As shown in FIG, the starting time slots of the SPS PDSCH corresponding to the 7 SPS configurations are offset by {0, 1, 2, 3, 4, 5, 6} time slots respectively, and the HARQ-ACK timing information corresponding to the 7 SPS configurations is configured as {2, 1, 2, 1, 2, 1, 1} time slots respectively, and the period of each SPS configuration is 10 time slots. Figure 9 As shown in (1), for the first data transmission cycle, the SPS PDSCH corresponding to SPS configuration 7 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 7. Since the data transmission unit of the SPS PDSCH corresponding to SPS configuration 7 is located at the end, the terminal device feeds back HARQ-ACK to the network device in the 4th HARQ-ACK feedback time unit 940 (time slot 7) corresponding to SPS configuration 7. Figure 9 As shown in (2), for the second data sending cycle, the SPS PDSCH corresponding to SPS configuration 4 carries data, and the terminal device correctly receives data in the SPS PDSCH corresponding to SPS configuration 4. Since the data transmission unit of the SPS PDSCH corresponding to SPS configuration 7 is at the end, the terminal device feeds back HARQ-ACK to the network device in the fourth HARQ-ACK feedback time unit 940 (time slot 17) corresponding to SPS configuration 7.

[0102] It should be noted that in the above embodiments, the present invention describes the feedback method for semi-persistent scheduling provided by the present invention from the perspective of the interaction between a terminal device and a network device. It should be understood that each step performed by the terminal device can be independently implemented as a feedback method for semi-persistent scheduling on the terminal device side; and each step performed by the network device can be independently implemented as a feedback method for semi-persistent scheduling on the network device side.
