Description

[0001] This application relates to the field of wireless communication, and particularly to a feedback method, apparatus, device, and storage medium for semi-persistent scheduling. Background Art

[0002] The NR (New Radio) system supports multiple SPS configurations (Semi-Persistent Schedule configurations), and for each SPS configuration's SPS PDSCH (Semi-Persistent Schedule Physical Downlink Shared Channel), HARQ-ACK (Hybrid Automatic Repeat request-Acknowledge character) needs to be fed back.

In the related art, in order to adapt to the fluctuations of data arrival, the network device often configures multiple SPS configurations to adapt to the data arriving at any time. In fact, within a transmission period of a downlink data, only one SPS PDSCH of one SPS configuration among multiple SPS configurations will carry data. That is, within the transmission period of this downlink data, only one SPS PDSCH needs to feedback HARQ-ACK, and the HARQ-ACK of other SPS PDSCHs is meaningless to the network device.

[0051] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0052] First, briefly introduce the nouns involved in the embodiments of the present application:

[0053] HARQ (Hybrid Automatic Repeat Request): It is a technology formed by combining Forward Error Correction (FEC) and Automatic Repeat-reQuest (ARQ). At the receiving end, the FEC technology is used to correct the part of all errors that can be corrected. Packets with errors that cannot be corrected are judged through error detection. The packets that cannot be error-corrected are discarded, and the same packets are requested to be resent to the transmitting end.

[0054] SPS (Semi-Persistent Schedule) configuration: Also known as semi-permanent scheduling, different from dynamically scheduling wireless resources for a UE (User Equipment) once per TTI (transmission time interval) (specified by PDCCH (Physical Uplink Control Channel)), the SPS configuration allows semi-static configuration of wireless resources and periodically allocates the resources to a specific UE. Simply put, the eNodeB (Evolved Node B) uses a PDCCH scrambled with SPSC-RNTI (Cell-Radio Network Temporary Identifier) to specify the SPS PDSCH used by the UE at a certain TTI. Every time a cycle passes, the UE uses this SPS PDSCH to receive or send data. The network device does not need to send a PDCCH in this subframe (referred to as the SPS subframe here) to specify the allocated resources. Due to the characteristic of "configured once and used multiple times" of the SPS configuration, it is not necessary to send DCI (Downlink Control Information) (including uplink or downlink DCI) to the UE at each TTI, thereby reducing the corresponding PDCCH overhead.

[0055] Figure 1 The block diagram of a communication system provided by an exemplary embodiment of the present application is shown. The communication system may include: an access network 12 and a terminal device 13.

[0056] The access network 12 includes several network devices 120. The network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functions for terminal devices. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems adopting different radio access technologies, the names of the devices with base station functions may be different. For example, in the LTE system, it is called eNodeB or eNB; in the 5G NR-U system, it is called gNodeB or gNB. With the evolution of communication technologies, the description of "base station" may change. For the convenience of the embodiments of this application, the device that provides wireless communication functions for the above terminal device 13 is collectively referred to as a network device.

[0057] The terminal device 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment, mobile stations (MS), terminal devices, etc. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The network device 120 and the terminal device 13 communicate with each other through a certain air interface technology, such as the Uu interface.

[0058] Optionally, the network device 120 transmits data through SPS configuration, and the terminal device 13 performs HARQ-ACK feedback on the SPS PDSCH.

[0059] The technical solution of the embodiments of this 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, New Radio (NR) system, evolved system of the NR system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication system or other communication systems, etc.

[0060] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technologies, mobile communication systems will not only support traditional communication but also support, for example, 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. Embodiments of this application can also be applied to these communication systems.

[0061] In the related art, the NR system supports multiple sets of SPS configurations. In order to adapt to the fluctuations of data arrival, network devices often configure at least one SPS configuration to adapt to the data arriving at any time. For each SPS PDSCH of each SPS configuration, the UE needs to feedback HARQ-ACK. However, although the network device configures one or more SPS configurations for the UE, the network device does not necessarily send data on all SPS PDSCHs of all SPS configurations. As Figure 2 shown, for a service with a transmission period of 4 time slots and a data arrival fluctuation range of 0-12 symbols, the network device configures 7 SPS configurations for this: SPS configuration 1, SPS configuration 2, SPS configuration 3, SPS configuration 4, SPS configuration 5, SPS configuration 6, and SPS configuration 7. The starting symbols of the SPS PDSCHs of the 7 SPS configurations are respectively offset by {0, 2, 4, 6, 8, 10, 12} symbols, and the period of each SPS configuration is 4 time slots. Therefore, actually within the same period, only one SPS configuration's SPS PDSCH among the 7 SPS configurations will carry data. For example, as Figure 2 shown in (1) below, the SPS PDSCH of SPS configuration 1 carries data, and the SPS PDSCHs of the remaining six SPS configurations do not carry data. Then the UE will feedback HARQ-ACK: A, N, N, N, N, N, N (1, 0, 0, 0, 0, 0, 0); where A represents ACK, that is, the acknowledgment character, used to indicate that the UE has received data on the SPS PDSCH of SPS configuration 1; N represents NACK, that is, the negative acknowledgment character, used to indicate that the UE has not received data on the SPS PDSCHs of SPS configuration 1 to SPS configuration 7. Again, for example, as Figure 2As shown in (2) therein, if the SPS PDSCH of SPS configuration 4 carries data and the SPS PDSCHs of the remaining six SPS configurations do not carry data, the UE will feedback HARQ-ACK: N,N,N,A,N,N,N(0,0,0,1,0,0,0). It can be seen that only one SPS PDSCH actually requires HARQ-ACK feedback, and the HARQ-ACKs of other SPS PDSCHs are meaningless to the network device.

[0062] Therefore, the present application provides a feedback method for semi-persistent scheduling. In the case of at least one SPS configuration, HARQ-ACK feedback is performed on the SPS PDSCHs corresponding to at least one SPS configuration according to HARQ-ACK groups, avoiding redundant and invalid HARQ-ACK feedback. It improves the reliability and efficiency of uplink transmission and reduces the power consumption of the terminal device.

[0063] Figure 3 The flowchart of the feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application is shown. This method can be applied to a terminal device in a communication system as shown in Figure 1 The method includes:

[0064] Step 201: The terminal device receives at least one semi-persistent scheduling SPS activation instruction sent by the network device. The SPS activation instruction is used to activate at least one SPS configuration among one or more SPS configurations (SPS configration) configured for the terminal device; each SPS configuration among the one or more SPS configurations corresponds to a Hybrid Automatic Repeat reQuest - ACKnowledgment (HARQ-ACK) group.

[0065] Schematically, the SPS activation instruction is carried in DCI (Downlink Control Information, downlink control information). Each SPS activation instruction is used to activate one SPS configuration. Alternatively, each SPS activation instruction is used to activate the SPS configuration information (SPSconfig) of one SPS configuration. However, in the embodiments of the present application, the possibility that one SPS activation instruction is used to activate more than two SPS configurations is not excluded.

[0066] The terminal device receives one or more SPS activation instructions and activates one SPS configuration according to each SPS activation instruction, or rather, activates the configuration information of one SPS configuration.

[0067] The network device sends one or more SPS configuration information to the terminal device in advance. Each SPS configuration information is used to configure one SPS configuration. Each SPS configuration information includes, but is not limited to, configuration parameters such as the period of the SPS configuration, the number of repetitions of the SPS configuration, and the resource location of the SPS configuration.

[0068] Among the configuration parameters carried in each SPS configuration information, the packet information of the HARQ-ACK packet is also carried. The packet information is used to indicate the HARQ-ACK packet corresponding to the SPS configuration, and the packet information may be a packet identifier.

[0069] When the terminal device is configured with multiple SPS configurations, the multiple SPS configurations may correspond to or belong to the same HARQ-ACK packet, or may correspond to or belong to different HARQ-ACK packets.

[0070] For example, the terminal device is configured with 7 SPS configurations, and the 7 SPS configurations correspond to the same HARQ-ACK packet; for another example, SPS configuration 1, SPS configuration 2, and SPS configuration 3 among the 7 SPS configurations correspond to the first HARQ-ACK packet, and SPS configuration 4, SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the second HARQ-ACK packet.

[0071] Step 202: The terminal device receives data on the SPS PDSCH corresponding to at least one SPS configuration, and feeds back HARQ-ACK to the network device according to the HARQ-ACK packet corresponding to at least one SPS configuration.

[0072] Illustratively, within the same data transmission period, the network device only sends data on the SPS PDSCH corresponding to a certain SPS configuration among at least one SPS configuration, and the data is downlink data. The SPS configuration corresponding to the SPS PDSCH carrying the data is unknown to the terminal device or cannot be predicted by the terminal device.

[0073] The terminal device receives data on the SPS PDSCH corresponding to at least one SPS configuration, and feeds back HARQ-ACK to the network device according to the HARQ-ACK packet corresponding to at least one SPS configuration.

[0074] Illustratively, when there is more than one SPS configuration corresponding to the same HARQ-ACK packet, the HARQ-ACK is used to indicate the reception situation on the SPS PDSCH where effective data transmission has occurred.

[0075] In summary, the method provided in this embodiment simplifies the HARQ-ACK feedback method of the terminal device by grouping at least one SPS configuration, with each SPS configuration corresponding to its own HARQ-ACK packet, enabling the terminal device to feed back HARQ-ACK to the network device according to the HARQ-ACK packet, avoiding the feedback of redundant and ineffective HARQ-ACK, improving the reliability and efficiency of uplink transmission, and reducing the power consumption of the terminal device.

[0076] Figure 4 The flowchart shows a feedback method for semi - persistent scheduling provided by an exemplary embodiment of the present application. This method can be applied to a network device in a communication system as shown in Figure 1 The method includes:

[0077] Step 301: The network device sends at least one SPS activation instruction to the terminal device. The SPS activation instruction is used to activate at least one SPS configuration among one or more SPS configurations configured for the terminal device; each SPS configuration among the one or more SPS configurations corresponds to a HARQ - ACK packet;

[0078] The network device sends one or more SPS activation instructions. Each SPS activation instruction is used to activate one SPS configuration. Alternatively, each SPS activation instruction is used to activate the SPS configuration information (SPS config) of one SPS configuration. However, in the embodiments of the present application, the possibility that one SPS activation instruction is used to activate more than two SPS configurations is not excluded.

[0079] Schematically, the SPS activation instruction is carried in the DCI. The network device sends one or more DCIs, and each DCI carries one SPS activation instruction. Optionally, the DCI is carried in the PDCCH (Physical Downlink Control Channel, PDCCH).

[0080] The network device also sends one or more SPS configuration information to the terminal device in advance. Each SPS configuration information is used to configure one SPS configuration. Each SPS configuration information includes, but is not limited to, configuration parameters such as the period of the SPS configuration, the number of repetitions of the SPS configuration, and the resource location of the SPS configuration.

[0081] Among the configuration parameters carried in each SPS configuration information, the packet information of the HARQ - ACK packet is also carried. The packet information is used to indicate the HARQ - ACK packet corresponding to the SPS configuration, and the packet information can be a packet identifier.

[0082] In the case where the terminal device is configured with multiple SPS configurations, the multiple SPS configurations can correspond to or belong to the same HARQ - ACK packet, or can correspond to or belong to different HARQ - ACK packets.

[0083] For example, the terminal device is configured with 7 SPS configurations, and the 7 SPS configurations correspond to the same HARQ - ACK packet; for another example, SPS configuration 1, SPS configuration 2, and SPS configuration 3 among the 7 SPS configurations correspond to the first HARQ - ACK packet, and SPS configuration 4, SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the second HARQ - ACK packet.

[0084] Step 302: The network device sends data to the terminal device on the SPS PDSCH corresponding to at least one SPS configuration;

[0085] Due to the jitter in data arrival, within the same data transmission period, the network device only sends data on the SPS PDSCH corresponding to a certain SPS configuration among one or more SPS configurations, and this data is downlink data. The SPS configuration corresponding to the SPS PDSCH carrying data is unknown to the terminal device or cannot be predicted by the terminal device.

[0086] Step 303: The network device receives the HARQ-ACK fed back by the terminal device, and the HARQ-ACK is fed back by the terminal device according to the HARQ-ACK group corresponding to at least one SPS configuration.

[0087] Illustratively, when there is more than one SPS configuration corresponding to the same HARQ-ACK group, the HARQ-ACK is used to indicate the reception situation on the SPS PDSCH where effective data transmission has occurred.

[0088] In summary, the method provided in this embodiment simplifies the HARQ-ACK feedback method of the terminal device, avoids feedback of redundant and invalid HARQ-ACKs, improves the reliability and efficiency of uplink transmission, and reduces the power consumption of the terminal device by grouping at least one SPS configuration, where each SPS configuration corresponds to its own HARQ-ACK group, and the terminal device feeds back the HARQ-ACK to the network device according to the HARQ-ACK group.

[0089] Figure 5 shows a flowchart of a semi-persistent scheduling feedback method provided by an exemplary embodiment of the present application. This method can be applied to a communication system as shown in Figure 1 and includes:

[0090] Step 401: The network device sends one or more SPS configuration information corresponding to one or more SPS configurations. Each SPS configuration information corresponds to an SPS configuration, and each SPS configuration information includes the grouping information of the HARQ-ACK group corresponding to the SPS configuration.

[0091] Exemplarily, the network device sends SPS configuration information (such as SPS-Config) of one or more SPS configurations (SPS configration) to the terminal device through RRC (Radio Resource Control) signaling. Each RRC signaling is used to send SPS configuration information corresponding to one SPS configuration, but this embodiment does not exclude the possibility that one RRC signaling is used to send multiple SPS configuration information corresponding to multiple SPS configurations.

[0092] Each SPS configuration corresponds to one SPS configuration information, and each SPS configuration information includes configuration information of one or more SPS PDSCHs. Exemplarily, the network device adds grouping information of the HARQ-ACK packet corresponding to the SPS configuration to the configuration parameters of each SPS configuration information. The grouping information may be the HARQ-ACK group ID (HARQ-ACK packet identifier).

[0093] For example, the network device sends 7 SPS configuration information (SPS-configs) to the terminal device. Each SPS configuration information corresponds to one SPS configuration (SPS configuration), and grouping information of the HARQ-ACK packet corresponding to the SPS configuration (for example, HARQ-ACK group ID). If the HARQ-ACK group IDs in these 7 SPS configuration information are the same, then these 7 SPS configurations correspond to the same HARQ-ACK packet. When there is data transmission on the PDSCHs corresponding to these 7 SPS configurations, the terminal device will use the same HARQ-ACK resource to feedback HARQ-ACK. Exemplarily, the same HARQ-ACK resource refers to the same HARQ-ACK feedback time unit.

[0094] For example, as shown in Table 1, the network device sends three SPS configuration information to the terminal device to indicate three SPS configurations. Each SPS configuration information includes the period, frequency domain position, HARQ-ACK group ID, etc. of the SPS configuration. It can be seen from Table 1 that the HARQ-ACK group IDs of the three SPS configurations are all 001, so the three SPS configurations belong to the same HARQ-ACK packet.

[0095] Table 1

[0096] SPS Configuration Information SPS Configuration Period Frequency Domain Position HARQ-ACK group ID SPS Configuration Information 1 SPS Configuration 1 6 symbols Frequency Domain Position 1 001 SPS Configuration Information 2 SPS Configuration 2 6 symbols Frequency Domain Position 2 001 SPS Configuration Information 3 SPS Configuration 3 6 symbols Frequency Domain Position 3 001

[0097] Exemplarily, the above step 401 is optional. The above one or more SPS configuration information may also be pre-configured in the terminal device; or may be configured by the network device to the terminal device at one time and can be directly used when there is data to be sent subsequently.

[0098] Step 402: The terminal device receives one or more SPS configuration information corresponding to one or more SPS configurations. Each SPS configuration information corresponds to an SPS configuration, and each SPS configuration information includes packet information of a HARQ-ACK packet corresponding to the SPS configuration.

[0099] The terminal device receives one or more RRC signaling. Each RRC signaling carries SPS configuration information of an SPS configuration. However, in this embodiment, the possibility that one RRC signaling carries SPS configuration information of at least two SPS configurations is not excluded.

[0100] Optionally, the packet information of the HARQ-ACK packet is a HARQ-ACK packet identifier.

[0101] Step 403: The network device sends at least one semi-persistent scheduling SPS activation instruction to the terminal device. The SPS activation instruction is used to activate at least one SPS configuration among the one or more SPS configurations configured for the terminal device; each SPS configuration among the one or more SPS configurations corresponds to a hybrid automatic repeat request-acknowledgment (HARQ-ACK) packet.

[0102] Exemplarily, when the network device has downlink data to be sent, it sends an SPS activation instruction to the terminal device. The SPS activation instruction is used to activate the SPS configuration corresponding to at least one SPS configuration information among the one or more SPS configuration information. Exemplarily, the network device sends the SPS activation instruction to the terminal device through DCI signaling. Exemplarily, one SPS configuration corresponds to one SPS activation instruction. The SPS activation instruction indicates the time domain position of the SPS PDSCH in the first period of the SPS configuration to the terminal device through information such as slot offset and symbol position within the slot.

[0103] Exemplarily, the SPS activation instruction also carries SPS feedback timing information (Timing). The SPS feedback timing is used to indicate the HARQ-ACK feedback time unit corresponding to the SPS configuration, so that the terminal device feeds back HARQ-ACK to the network device through the HARQ-ACK feedback time unit. HARQ-ACK is used to inform the network device of the data reception situation of the terminal device on the SPS PDSCH corresponding to the SPS configuration.

[0104] The HARQ-ACK feedback time unit may be a time slot, a sub-slot, a symbol, a sub-frame, etc., and this embodiment does not limit this. The above SPS feedback timing information may directly indicate the HARQ-ACK feedback time unit corresponding to each SPS PDSCH; it may also be indirectly indicated by a feedback offset or parameter. For example, the SPS feedback timing information includes a feedback offset k, and this feedback offset k is used to indicate that the terminal device feeds back HARQ-ACK in the k-th time slot after the last time slot of receiving the SPS PDSCH.

[0105] Illustratively, there are multiple SPS configurations corresponding to the same HARQ-ACK packet, and the network device indicates the SPS feedback timing information to the multiple SPS configurations, so that the HARQ feedback time units of the multiple SPS configurations within the same HARQ feedback period are the same. For example, the same one or more HARQ feedback time units.

[0106] For example, the SPS activation instruction includes a symbol offset and a feedback offset. The terminal device adds the symbol offset b to the time domain position a of the received SPS activation instruction to obtain the time domain position a + b of the first SPS PDSCH of this SPS configuration. The terminal device obtains the HARQ-ACK feedback time unit n + k corresponding to this SPS PDSCH according to the feedback offset k and the time domain position n of the SPS PDSCH.

[0107] For example, as shown in Table 2, the network device sends three SPS activation instructions corresponding to three SPS configurations to the terminal device, and each SPS activation instruction includes the symbol offset, feedback offset, etc. of the SPS configuration.

[0108] Table 2

[0109] SPS Activation Instruction SPS Configuration Symbol Offset Feedback Offset SPS Activation Instruction 1 SPS Configuration 1 1 symbol 4 symbols

[0110] SPS Activation Instruction 2 SPS Configuration 2 2 symbols 3 symbols SPS Activation Instruction 3 SPS Configuration 3 3 symbols 2 symbols

[0111] Exemplarily, taking the example that the terminal device receives three SPS configuration information as shown in Table 1 and three SPS activation instructions as shown in Table 2, in combination with Figure 6Describe the configuration and activation process of SPS configurations. According to Table 1, the network device allocates three SPS configurations for the terminal device, which are located at frequency-domain positions 1, 2, and 3 respectively, and the periods of the three SPS configurations are all 6 symbols. Assume that the terminal device receives three SPS activation instructions sent by the network device at symbol 3. Then, according to Table 2, the first SPS PDSCH of SPS configuration 1 is symbol 3 offset by 1 symbol, which is equal to symbol 4, that is, the SPS PDSCH 701 located at frequency-domain position 1 and symbol 4; the first SPS PDSCH of SPS configuration 2 is symbol 3 offset by 2 symbols, which is equal to symbol 5, that is, the SPS PDSCH 702 located at frequency-domain position 2 and symbol 5; the first SPS PDSCH of SPS configuration 3 is symbol 3 offset by 3 symbols, which is equal to symbol 6, that is, the SPS PDSCH703 located at frequency-domain position 3 and symbol 6. According to the period of each SPS configuration (6 symbols), the symbol positions of the next SPS PDSCH of each SPS can be determined, that is, as Figure 6 shown, the SPS PDSCHs in the shaded part of the figure. According to Table 2, the feedback offset of SPS configuration 1 is 4 symbols. Then, for the first SPS PDSCH of SPS configuration 1, its HARQ-ACK feedback time unit is symbol 4 plus 4 symbols, which is equal to symbol 8; the feedback offset of SPS configuration 2 is 3 symbols. Then, for the first SPS PDSCH of SPS configuration 2, its HARQ-ACK feedback time unit is symbol 5 plus 3 symbols, which is equal to symbol 8; the feedback offset of SPS configuration 3 is 2 symbols. Then, for the first SPS PDSCH of SPS configuration 3, its HARQ-ACK feedback time unit is symbol 6 plus 2 symbols, which is equal to symbol 8. It can be seen that the three SPS configurations all feedback HARQ-ACK at symbol 8, so the three SPS configurations belong to the same HARQ-ACK feedback time unit.

[0112] Exemplarily, the network device can group multiple SPS configurations configured for the terminal device into the same HARQ-ACK group, or divide multiple SPS configurations into multiple different HARQ-ACK groups.

[0113] Exemplarily, after the network device configures multiple SPS configurations for the terminal device, it can activate all the multiple SPS configurations, or only activate a part of them.

[0114] Exemplarily, the SPS configurations in the same HARQ-ACK group can point to the same HARQ-ACK feedback time unit, or point to different HARQ-ACK feedback time units.

[0115] In an exemplary embodiment, for SPS configurations with the same HARQ-ACK packet (e.g., the same HARQ-ACK group ID), the SPS feedback timing information points to the same feedback time (HARQ-ACK feedback time unit), for example, the same slot, the same subslot, the same one or several symbols, or the same subframe, etc. In another exemplary embodiment, for SPS configurations with the same HARQ-ACK packet (e.g., the same HARQ-ACK group ID), the SPS feedback timing information points to different feedback times (HARQ-ACK feedback time units), for example, different slots, different subslots, different symbols, or different subframes, etc.

[0116] The unit of the feedback time can be related to the priority in the SPS activation instruction. For example, a high priority corresponds to a sub-slot, and a low priority corresponds to a slot. The corresponding relationship can be configured by a higher layer. Exemplarily, the SPS feedback timing information is carried by the SPS activation signaling. Exemplarily, the SPS feedback timing information can also be configured by higher layer signaling.

[0117] Exemplarily, the HARQ-ACK feedback time unit in the above example is independently set for each SPS configuration; the HARQ-ACK feedback time unit can also be independently set for each HARQ-ACK packet. For example, the first HARQ-ACK feedback time unit is indicated for the first HARQ-ACK packet.

[0118] Step 404: The terminal device receives at least one semi-persistent scheduling SPS activation instruction sent by the network device, and the SPS activation instruction is used to activate at least one SPS configuration among one or more SPS configurations configured for the terminal device; each SPS configuration among the one or more SPS configurations corresponds to a hybrid automatic repeat request-acknowledgment (HARQ-ACK) packet.

[0119] Step 405: The network device sends data to the terminal device on the SPS PDSCH corresponding to at least one SPS configuration.

[0120] Step 406: The terminal device receives the data on the SPS PDSCH corresponding to at least one SPS configuration.

[0121] Since each SPS configuration information includes the packet information of the HARQ-ACK packet corresponding to the corresponding SPS configuration. Therefore, the terminal device can send HARQ-ACK to the network device according to the packet information of the HARQ-ACK packet corresponding to the at least one activated SPS configuration above, in accordance with the HARQ-ACK packet. The network device receives the received HARQ-ACK sent by the terminal device. For example, when the above at least one SPS configuration corresponds to the same HARQ-ACK packet, when the terminal device correctly receives data on the SPS PDSCH corresponding to any one or several SPS configurations of the at least one SPS configuration, it can feedback HARQ-ACK through the HARQ-ACK resource corresponding to the HARQ-ACK packet.

[0122] For example, when the terminal device in step 406 correctly receives data on the SPS PDSCH corresponding to the activated at least one SPS configuration information, it feedbacks ACK. If data is not correctly received on all the AP APD SCHs corresponding to the at least one SPS configuration information, it feedbacks NACK.

[0123] Step 407: The terminal device feedbacks HARQ-ACK to the network device according to the HARQ-ACK packet corresponding to the at least one SPS configuration.

[0124] Step 408: The network device receives the HARQ-ACK feedback by the terminal device, and the HARQ-ACK is feedback by the terminal device according to the HARQ-ACK packet corresponding to the at least one SPS configuration.

[0125] Exemplarily, this technology can also be used for sidelink, that is, communication between terminal devices.

[0126] In summary, the method provided in this embodiment simplifies the HARQ-ACK feedback method by grouping the SPS PDSCHs corresponding to at least one SPS configuration, enabling the terminal device to perform HARQ-ACK feedback according to the HARQ-ACK packet, avoiding redundant and invalid HARQ-ACK feedback, improving the reliability and efficiency of uplink transmission, and reducing the power consumption of the terminal device.

[0127] Exemplarily, this application gives six exemplary embodiments for enabling the terminal device to perform HARQ-ACK feedback according to the HARQ-ACK packet.

[0128] First, the feedback information bit corresponding to a HARQ-ACK packet can be 1 bit, or can be n bits determined according to the number of SPS configurations in the HARQ-ACK packet. Then, multiple SPS configurations in the same HARQ-ACK packet may feedback HARQ-ACK through the same HARQ-ACK feedback time unit, or may feedback HARQ-ACK through multiple different HARQ-ACK feedback time units. When the SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through multiple different HARQ-ACK feedback time units, the terminal device may feedback HARQ-ACK in each HARQ-ACK feedback time unit, or may only feedback HARQ-ACK in the last HARQ-ACK feedback time unit.

[0129] Therefore, the present embodiment gives exemplary embodiments of the following six cases:

[0130] 1. The SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through the same HARQ-ACK feedback time unit, and the HARQ-ACK packet occupies 1 bit of feedback information bit in the HARQ-ACK feedback time unit.

[0131] 2. The SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through the same HARQ-ACK feedback time unit, and the HARQ-ACK packet occupies n bits of feedback information bit in the HARQ-ACK feedback time unit, where n is the number of SPS configurations in the HARQ-ACK packet.

[0132] 3. The SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units, the HARQ-ACK packet occupies 1 bit of feedback information bit in each HARQ-ACK feedback time unit, and feedbacks HARQ-ACK in each HARQ-ACK feedback time unit.

[0133] 4. The SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units, the HARQ-ACK packet occupies 1 bit of feedback information bit in the last HARQ-ACK feedback time unit, and only feedbacks HARQ-ACK in the last HARQ-ACK feedback time unit.

[0134] 5. The SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units, and occupies n in each HARQ-ACK feedback time unit jbit feedback information bits, and HARQ-ACK is fed back in each HARQ-ACK feedback time unit, where n j is the number of SPS configurations corresponding to the j-th HARQ-ACK feedback time unit.

[0135] 6. For the SPS configurations of the same HARQ-ACK packet, HARQ-ACK is fed back through different HARQ-ACK feedback time units, and in the last HARQ-ACK feedback time unit, it occupies n k bit feedback information bits, and HARQ-ACK is only fed back in the last HARQ-ACK feedback time unit, where n k is the number of SPS configurations corresponding to the last HARQ-ACK feedback time unit.

[0136] Exemplary embodiments for the first case.

[0137] That is, for the SPS configurations of the same HARQ-ACK packet, HARQ-ACK is fed back through the same HARQ-ACK feedback time unit, and this HARQ-ACK packet occupies 1 bit of feedback information bit in the HARQ-ACK feedback time unit.

[0138] Figure 7 Shows a flowchart of a feedback method for semi-static scheduling provided by an exemplary embodiment of the present application. This method can be applied to a terminal device in a communication system as shown in Figure 1 Based on the exemplary embodiment shown in Figure 5 Before step 406, step 501 is further included, and step 406 further includes step 4061:

[0139] Exemplarily, there are n activated SPS configurations corresponding to the first HARQ-ACK packet; the n SPS configurations of the first HARQ-ACK packet correspond to the same HARQ-ACK feedback time unit, and n is a positive integer; the first HARQ-ACK packet corresponds to 1 bit of feedback information bit, and n is a positive integer. Exemplarily, the terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations, and feeds back HARQ-ACK to the network device through the 1-bit feedback information bit of the first HARQ-ACK packet corresponding to the n SPS configurations.

[0140] Step 501: The terminal device generates a 1-bit HARQ-ACK according to the reception situation of the SPS PDSCH on which effective data transmission occurs among the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer; or, the terminal device generates a 1-bit HARQ-ACK according to the logical OR result of the reception situations of the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer.

[0141] For example, as Figure 8 shown, if the network device divides 7 SPS configurations into the same HARQ-ACK group, then n is 7, and the SPS configurations in this HARQ-ACK group correspond to the same HARQ-ACK feedback time unit 601. The terminal device uses 1-bit HARQ-ACK through the HARQ-ACK feedback time unit 601 to feedback to the network device the data reception situation on the SPS PDSCHs of the 7 SPS configurations.

[0142] Step 4061: The terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations, and feeds back HARQ-ACK to the network device through the 1-bit feedback information bit of the first HARQ-ACK group corresponding to the n SPS configurations.

[0143] Exemplarily, if the terminal device correctly receives data on a certain SPS PDSCH among the n SPS configurations (the SPS PDSCH carries data and the data is correctly received by the terminal device), then the terminal device feeds back 1-bit HARQ-ACK: ACK to the network device to indicate that the data has been correctly received. If the terminal device does not correctly receive data on all n SPS PDSCHs, then the terminal device feeds back 1-bit HARQ-ACK: NACK to the network device to indicate that the data has not been correctly received. Therefore, the terminal device only needs to send 1-bit HARQ-ACK to the network device to inform the network device whether the data has been correctly received in the current period, thereby reducing the data volume of the HARQ-ACK sent by the terminal device, improving the uplink transmission efficiency, and reducing the power consumption of the terminal device.

[0144] Exemplarily, the terminal device can also perform an "OR" operation on the HARQ-ACKs of the SPS PDSCHs in the same HARQ-ACK group, that is, as long as the terminal device correctly receives data on at least one SPS PDSCH in the same HARQ-ACK group, the terminal device feeds back ACK. Only when all SPS PDSCHs in the same HARQ-ACK group have not been correctly received, NACK is fed back.

[0145] For example, as Figure 8 shown in (1) below, the SPS PDSCH of SPS configuration 7 carries data, and the terminal device correctly receives the data on the SPS PDSCH of SPS configuration 7. Then the terminal device generates 1-bit HARQ-ACK: ACK and sends this HARQ-ACK: ACK to the network device. As Figure 8As shown in (2) in [reference], data is carried on the SPS PDSCH of SPS configuration 4. If the terminal device correctly receives data on the SPS PDSCH of SPS configuration 4, the terminal device generates a 1-bit HARQ-ACK: ACK and sends this HARQ-ACK: ACK to the network device.

[0146] In summary, the method provided in this embodiment enables the terminal device to generate a 1-bit HARQ-ACK according to whether it correctly receives data on the SPS PDSCH in a HARQ-ACK packet. If the terminal device correctly receives data, it feeds back ACK to the network device; if the terminal device does not correctly receive data, it feeds back NACK. Thereby, the data volume of the terminal device for sending HARQ-ACK is reduced, the uplink transmission efficiency is improved, and the power consumption of the terminal device is reduced.

[0147] Exemplary embodiment for the second case.

[0148] That is, the SPS configurations of the same HARQ-ACK packet feed back HARQ-ACK through the same HARQ-ACK feedback time unit, and this HARQ-ACK packet occupies n-bit feedback information bits in the HARQ-ACK feedback time unit, where n is the number of SPS configurations in the HARQ-ACK packet.

[0149] Figure 9 Shows a flowchart of a feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application. This method can be applied to a terminal device in a communication system as shown in Figure 1 As shown, based on the exemplary embodiment shown in Figure 5 Before step 406, step 502 is further included, and step 406 further includes step 4062:

[0150] Exemplarily, there are n activated SPS configurations corresponding to the first HARQ-ACK packet; the n SPS configurations of the first HARQ-ACK packet correspond to the same HARQ-ACK feedback time unit, where n is a positive integer; the first HARQ-ACK packet corresponds to n-bit feedback information bits, where n is a positive integer; Exemplarily, the terminal device receives data on at least one SPS PDSCH corresponding to the n SPS configurations and feeds back HARQ-ACK to the network device through the 1-bit feedback information bits of the first HARQ-ACK packet corresponding to the n SPS configurations.

[0151] Step 502: The terminal device generates n-bit HARQ-ACK with the same value according to the reception of the SPS PDSCHs on which valid data transmission occurs among the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer; or, the terminal device generates n-bit HARQ-ACK with the same value according to the logical OR result of the reception of the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer.

[0152] Step 4062: The terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations and feeds back HARQ-ACK to the network device through the n-bit feedback information bits of the first HARQ-ACK packet corresponding to the n SPS configurations.

[0153] For example, as Figure 10 shown, if the network device divides 7 SPS configurations into the same HARQ-ACK packet, then n is 7, and the SPS PDSCHs in this HARQ-ACK packet correspond to the same HARQ-ACK feedback time unit 601. The terminal device feeds back the data reception on the SPS PDSCHs of the 7 SPS configurations to the network device with 7-bit HARQ-ACK through the HARQ-ACK feedback time unit 601.

[0154] Exemplarily, if the terminal device correctly receives data on at least one SPS PDSCH among the n SPS configurations (the SPS PDSCH carries data and the data is successfully received by the terminal device), the terminal device feeds back n-bit feedback information: n ACKs, to indicate that the data has been correctly received. If the terminal device does not correctly receive data on any of the SPS PDSCHs among the n SPS configurations, the terminal device feeds back n-bit feedback information: n NACKs, to indicate that the data has not been correctly received. Therefore, the terminal device sends n-bit identical HARQ-ACK to the network device to inform the network device whether the data has been correctly received in the current period. If the data is correctly received, n ACKs are sent; if the data is not correctly received, n NACKs are sent. This improves the reliability of the uplink transmission of the terminal device. Even if some HARQ-ACKs are interfered during the communication process, the network device can accurately determine whether the terminal device has correctly received the data. For example, if two of the 7 ACKs sent by the terminal device are interfered and become NACKs, the network device can still determine that the terminal device has correctly received the data based on the ACKs that are in the majority in the HARQ-ACK.

[0155] For example, as Figure 10As shown in (1) in [reference], the SPS PDSCH of SPS configuration 7 carries data. If the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7, the terminal device generates a 7-bit HARQ-ACK: ACK, ACK, ACK, ACK, ACK, ACK, ACK, and sends this HARQ-ACK: ACK, ACK, ACK, ACK, ACK, ACK, ACK to the network device. As Figure 10 As shown in (2) in [reference], the SPS PDSCH of SPS configuration 4 carries data. If the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 4, the terminal device generates a 7-bit HARQ-ACK: ACK, ACK, ACK, ACK, ACK, ACK, ACK, and sends this HARQ-ACK: ACK, ACK, ACK, ACK, ACK, ACK, ACK to the network device.

[0156] In summary, the method provided in this embodiment enables the terminal device to generate an n-bit HARQ-ACK according to whether the data is correctly received on the SPS PDSCH of the SPS configuration in a HARQ-ACK packet. If the terminal device correctly receives the data, it feeds back n ACKs to the network device. If the terminal device does not correctly receive the data, it feeds back n NACKs, thereby improving the accuracy of the uplink transmission.

[0157] An exemplary embodiment for the third case.

[0158] That is, the SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units. This HARQ-ACK packet occupies 1 bit of feedback information bit in each HARQ-ACK feedback time unit, and HARQ-ACK is fed back in each HARQ-ACK feedback time unit.

[0159] Figure 11 shows a flowchart of a feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application. This method can be applied to a terminal device in a communication system as shown in Figure 1 Based on the exemplary embodiment shown in Figure 5 Before step 406, step 503 is further included, and step 406 further includes step 4063:

[0160] There are n activated SPS configurations corresponding to a second HARQ-ACK packet; the n SPS configurations of the second HARQ-ACK packet correspond to K HARQ-ACK feedback time units, where K is a positive integer; each HARQ-ACK feedback time unit corresponds to 1 bit of feedback information bit, and the second HARQ-ACK packet corresponds to a total of K bits of feedback information bits, where n and K are positive integers; Exemplarily, the terminal device receives data on the SPS PDSCH corresponding to n SPS configurations and feeds back HARQ-ACK to the network device within the K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0161] Step 503: The terminal device generates a 1-bit HARQ-ACK corresponding to the j-th HARQ-ACK feedback time unit according to the reception situation of the SPS PDSCHs on which valid data transmission occurs among the n SPS PDSCHs corresponding to the j-th HARQ-ACK feedback time unit; generate K bits of HARQ-ACK corresponding to K HARQ-ACK feedback time units, where n is a positive integer less than or equal to n, and j is a positive integer less than or equal to K; or, the terminal device generates a 1-bit HARQ-ACK corresponding to the j-th HARQ-ACK feedback time unit according to the logical OR result of the reception situations of the n SPS PDSCHs corresponding to the j-th HARQ-ACK feedback time unit; generate K bits of HARQ-ACK corresponding to K HARQ-ACK feedback time units, where n is a positive integer less than or equal to n, and j is a positive integer less than or equal to K. j among the n j SPS PDSCHs corresponding to the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit; generate K bits of HARQ-ACK corresponding to K HARQ-ACK feedback time units, where n j is a positive integer less than or equal to n, and j is a positive integer less than or equal to K; or, the terminal device generates a 1-bit HARQ-ACK corresponding to the j-th HARQ-ACK feedback time unit according to the logical OR result of the reception situations of the n j SPS PDSCHs corresponding to the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit; generate K bits of HARQ-ACK corresponding to K HARQ-ACK feedback time units, where n

[0162] Step 4063: The terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations and feeds back HARQ-ACK to the network device through the K-bit feedback information bits of the K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0163] For example, as Figure 12As shown, the network device groups 7 SPS configurations into the same HARQ-ACK packet. Then n is 7, and the SPS configurations in this packet correspond to two HARQ-ACK feedback time units: the first HARQ-ACK feedback time unit 1001 and the second HARQ-ACK feedback time unit 1002, that is, K is 2. Among them, SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4 correspond to the first HARQ-ACK feedback time unit 1001; SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the second HARQ-ACK feedback time unit 1002. That is, 4 SPS configurations correspond to the first HARQ-ACK feedback time unit; 3 SPS configurations correspond to the second HARQ-ACK feedback time unit. The terminal device uses 1-bit HARQ-ACK in two HARQ-ACK feedback time units respectively to feedback to the network device the data reception situation on the SPS PDSCH of 7 SPS configurations.

[0164] Exemplarily, the terminal device determines the HARQ-ACK on the j-th HARQ-ACK feedback time unit according to the data reception situation in the SPS PDSCH of the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit. If the terminal device correctly receives data on at least one SPS PDSCH among the SPS PDSCH of the n j SPS configurations, the terminal device uses the j-th HARQ-ACK feedback time unit to feedback 1-bit HARQ-ACK to the network device: ACK, to indicate that it has correctly received data in the SPS PDSCH of the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit. If the terminal device does not correctly receive data on the SPS PDSCH of the n j SPS configurations, the terminal device uses the j-th HARQ-ACK feedback time unit to feedback 1-bit HARQ-ACK to the network device: NACK, to indicate that it does not correctly receive data in the SPS PDSCH of the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit. Therefore, the terminal device only needs to send 2 bits of HARQ-ACK to the network device to inform the network device whether it has correctly received data in the current period, thereby reducing the data volume of the terminal device sending HARQ-ACK, improving the uplink transmission efficiency, and reducing the power consumption of the terminal device.

[0165] Exemplarily, the terminal device may also perform an "OR" operation on the HARQ-ACKs corresponding to the same SPS configuration for the same HARQ-ACK feedback time unit, that is, as long as at least one SPS PDSCH corresponding to the same SPS configuration for the same HARQ-ACK feedback time unit correctly receives data, the terminal device feeds back ACK. Only when all SPS PDSCHs corresponding to the same SPS configuration for the same HARQ-ACK feedback time unit do not correctly receive data, NACK is fed back.

[0166] For example, as Figure 12 shown in (1) of, the SPS PDSCH of SPS configuration 7 carries data, and the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7. Since the terminal device does not correctly receive data in the SPS PDSCHs of the first 4 SPS configurations (there is no data on the SPS PDSCHs of the first four SPS configurations), the terminal device generates 1-bit HARQ-ACK at the first HARQ-ACK feedback time unit 1001: NACK; since the terminal device does not correctly receive data in the SPS PDSCHs of SPS configuration 5 and SPS configuration 6 and correctly receives data in the SPS PDSCH of SPS configuration 7, 1-bit HARQ-ACK is generated at the second HARQ-ACK feedback time unit 1002: ACK, and two HARQ-ACKs of two HARQ-ACK feedback time units, NACK and ACK, are sent to the network device. As Figure 12 shown in (2) of, the SPS PDSCH of SPS configuration 4 carries data, the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 4, and does not correctly receive data in the SPS PDSCHs of the other 6 SPS configurations. Then the terminal device generates 1-bit HARQ-ACK at the first HARQ-ACK feedback time unit 1001: ACK, and generates 1-bit HARQ-ACK at the second HARQ-ACK feedback time unit 1002: NACK, and sends two HARQ-ACKs of two HARQ-ACK feedback time units, ACK and NACK, to the network device.

[0167] In summary, for the method provided in this embodiment, the terminal device generates a 1-bit HARQ-ACK in each HARQ-ACK feedback time unit according to whether data is correctly received on at least one SPS configuration corresponding to the HARQ-ACK feedback time unit. If the terminal device correctly receives the data, it feeds back ACK to the network device through this HARQ-ACK feedback time unit; if the terminal device does not correctly receive the data, it feeds back NACK to the network device through this HARQ-ACK feedback time unit. Thereby, the amount of data for the terminal device to send HARQ-ACK is reduced, the uplink transmission efficiency is improved, and the power consumption of the terminal device is reduced.

[0168] An exemplary embodiment for the 4th scenario.

[0169] That is, for the SPS configurations of the same HARQ-ACK packet, HARQ-ACK is fed back through different HARQ-ACK feedback time units. This HARQ-ACK packet occupies 1 bit of feedback information bit in the last HARQ-ACK feedback time unit, and HARQ-ACK is only fed back in the last HARQ-ACK feedback time unit.

[0170] Figure 13 The flowchart of the feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application is shown. This method can be applied to a terminal device in a communication system as shown in Figure 1 Based on the exemplary embodiment shown in Figure 5 Before step 406, step 504 is further included, and step 406 further includes step 4064:

[0171] There are n activated SPS configurations corresponding to the second HARQ-ACK packet; the n SPS configurations of the second HARQ-ACK packet correspond to K HARQ-ACK feedback time units, where K is a positive integer; the Kth HARQ-ACK feedback time unit corresponds to 1 bit of feedback information bit, and the second HARQ-ACK packet corresponds to a total of 1 bit of feedback information bit, where n and K are positive integers; Exemplarily, the terminal device receives data on the SPS PDSCH corresponding to n SPS configurations and feeds back HARQ-ACK to the network device in the K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0172] Step 504: The terminal device generates a 1-bit HARQ-ACK according to the reception situation of the SPS PDSCH on which effective data transmission occurs among the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer; or, the terminal device generates a 1-bit HARQ-ACK according to the logical OR result of the reception situations of the n SPS PDSCHs corresponding to the n SPS configurations, where n is a positive integer.

[0173] Step 4064: The terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations, and feeds back HARQ-ACK to the network device through the 1-bit feedback information bit of the Kth HARQ-ACK feedback time unit corresponding to the n SPS configurations.

[0174] For example, as Figure 14 shown, if the network device divides 7 SPS configurations into the same HARQ-ACK group, then n is 7, and the SPS configurations in this group correspond to two HARQ-ACK feedback time units: the 1st HARQ-ACK feedback time unit 1001 and the 2nd HARQ-ACK feedback time unit 1002, that is, K is 2. Among them, SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4 correspond to the 1st HARQ-ACK feedback time unit 1001; SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the 2nd HARQ-ACK feedback time unit 1002. That is, 4 SPS configurations corresponding to the 1st HARQ-ACK feedback time unit; 3 SPS configurations corresponding to the 2nd HARQ-ACK feedback time unit. The terminal device only feeds back to the network device the data reception situation on the SPS PDSCH of the 7 SPS configurations with 1-bit HARQ-ACK through the 2nd HARQ-ACK feedback time unit.

[0175] Exemplarily, the terminal device determines the HARQ-ACK on the Kth HARQ-ACK feedback time unit (the last HARQ-ACK feedback time unit) according to the data reception situation in the SPS PDSCH of the n SPS configurations in a HARQ-ACK group. If the terminal device correctly receives data on at least one SPS PDSCH among the SPS PDSCH of the n SPS configurations, the terminal device feeds back 1-bit HARQ-ACK: ACK to the network device through the Kth HARQ-ACK feedback time unit to indicate correct data reception. If the terminal device does not correctly receive data on any of the SPS PDSCH of the n SPS configurations, the terminal device feeds back 1-bit HARQ-ACK: NACK to the network device through the Kth HARQ-ACK feedback time unit to indicate incorrect data reception. Therefore, the terminal device only needs to send 1-bit HARQ-ACK to the network device to inform the network device whether it has correctly received data in the current period, thereby reducing the data volume of the terminal device for sending HARQ-ACK, improving the uplink transmission efficiency, and reducing the power consumption of the terminal device.

[0176] Exemplarily, the terminal device can also perform an "OR" operation on the HARQ-ACKs of the SPS configurations of the same HARQ-ACK packet, that is, as long as at least one SPS PDSCH in the SPS configurations of the same HARQ-ACK packet correctly receives data, the terminal device feeds back ACK. Only when all SPS PDSCHs in the SPS configurations of the same HARQ-ACK packet do not correctly receive data, NACK is fed back.

[0177] For example, as Figure 14 shown in (1) of, the SPS PDSCH of SPS configuration 7 carries data, and the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7. Since the terminal device does not correctly receive data in the SPS PDSCHs of the previous 6 SPS configurations (there is no data on the SPS PDSCHs of the previous 6 SPS configurations), and the terminal device correctly receives data in the SPS PDSCH of SPS configuration 7, the terminal device generates a 1-bit HARQ-ACK: ACK at the second HARQ-ACK feedback time unit 1002 and sends HARQ-ACK: ACK to the network device. As Figure 14 shown in (2) of, the SPS PDSCH of SPS configuration 4 carries data, the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 4, and does not correctly receive data in the SPS PDSCHs of the other 6 SPS configurations. Then the terminal device generates a 1-bit HARQ-ACK: ACK at the second HARQ-ACK feedback time unit 1002 and sends HARQ-ACK: ACK to the network device.

[0178] In summary, the method provided in this embodiment enables the terminal device to generate a 1-bit HARQ-ACK at the last HARQ-ACK feedback time unit according to whether the data is correctly received on the SPS PDSCH of the SPS configurations of the same HARQ-ACK packet. If the terminal device correctly receives the data, it feeds back ACK to the network device through the last HARQ-ACK feedback time unit. If the terminal device does not correctly receive the data, it feeds back NACK to the network device through the last HARQ-ACK feedback time unit. Thereby reducing the data volume of the HARQ-ACK sent by the terminal device, improving the uplink transmission efficiency, and reducing the power consumption of the terminal device.

[0179] An exemplary embodiment for the fifth scenario.

[0180] That is, the SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units, and occupy n in each HARQ-ACK feedback time unit jBit feedback information bits, and HARQ-ACK is fed back in each HARQ-ACK feedback time unit, where n j is the number of SPS configurations corresponding to the j-th HARQ-ACK feedback time unit.

[0181] Figure 15 shows a flowchart of a feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application. This method can be applied to a terminal device in a communication system as shown in Figure 1 Based on the exemplary embodiment shown in Figure 5 Before step 406, step 505 is further included, and step 406 further includes step 4065:

[0182] There are n SPS configurations corresponding to the second HARQ-ACK packet that are activated; the n SPS configurations of the second HARQ-ACK packet correspond to K HARQ-ACK feedback time units, where K is a positive integer; the j-th HARQ-ACK feedback time unit corresponds to n j bit feedback information bits, and the second HARQ-ACK packet corresponds to a total of n bit feedback information bits, where n j is the number of SPS configurations corresponding to the j-th HARQ-ACK feedback time unit, n is a positive integer, and n j is a positive integer less than or equal to n, and j is a positive integer less than or equal to K; Exemplarily, the terminal device receives data on the SPS PDSCH corresponding to n SPS configurations and feeds back HARQ-ACK to the network device within the K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0183] Step 505: The terminal device generates HARQ-ACK with the same value corresponding to the j-th HARQ-ACK feedback time unit according to the reception situation of the SPS PDSCH on which valid data transmission occurs among the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit, where there are n j SPS PDSCHs; generate HARQ-ACK with n bits corresponding to a total of K HARQ-ACK feedback time units, where n and K are positive integers, and n j is a positive integer less than or equal to n, and j is a positive integer less than or equal to K; or, the terminal device generates HARQ-ACK with the same value corresponding to the j-th HARQ-ACK feedback time unit according to the logical OR result of the reception situations of the n j SPS configurations corresponding to the j-th HARQ-ACK feedback time unit, where there are n j SPS PDSCHs; where there are n j SPS PDSCHs; generate HARQ-ACK with n bits corresponding to the j-th HARQ-ACK feedback time unit, where n jHARQ-ACK for bits; generate n-bit HARQ-ACK corresponding to K HARQ-ACK feedback time units, where n and K are positive integers, and n j is a positive integer less than or equal to n, and j is a positive integer less than or equal to K.

[0184] Step 4065: The terminal device receives data on at least one SPS PDSCH corresponding to n SPS configurations, and feeds back HARQ-ACK to the network device through the n-bit feedback information bits of the K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0185] For example, as Figure 16 shown, the network device divides 7 SPS configurations into the same HARQ-ACK group, then n takes 7, and the SPS configurations in this group correspond to two HARQ-ACK feedback time units: the first HARQ-ACK feedback time unit 1001 and the second HARQ-ACK feedback time unit 1002, that is, K takes 2. Among them, SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4 correspond to the first HARQ-ACK feedback time unit 1001; SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the second HARQ-ACK feedback time unit 1002. That is, 4 SPS configurations corresponding to the first HARQ-ACK feedback time unit; 3 SPS configurations corresponding to the second HARQ-ACK feedback time unit. The terminal device uses 4-bit HARQ-ACK in the first HARQ-ACK feedback time unit 1001 and 3-bit HARQ-ACK in the second HARQ-ACK feedback time unit 1002 to feed back the data reception situation on the SPS PDSCH of 7 SPS configurations to the network device.

[0186] Exemplarily, the terminal device determines the HARQ-ACK on the jth HARQ-ACK feedback time unit according to the data reception situation in the SPS PDSCH of the n j SPS configurations corresponding to the jth HARQ-ACK feedback time unit. If the terminal device correctly receives data on at least one SPS PDSCH among the SPS PDSCH of the n j SPS configurations, the terminal device feeds back n j bits of HARQ-ACK to the network device through the jth HARQ-ACK feedback time unit: n j ACKs, to indicate that the data has been correctly received in the SPS PDSCH of the n j SPS configurations corresponding to the jth HARQ-ACK feedback time unit. If the terminal device is in the n jIf no data is correctly received on the SPS PDSCHs configured with the SPS, the terminal device feeds back an n-bit HARQ-ACK to the network device through the j-th HARQ-ACK feedback time unit: n j NACKs, indicating that no data is correctly received in the n SPS PDSCHs configured with the SPS corresponding to the j-th HARQ-ACK feedback time unit. Thereby, the reliability of the uplink transmission of the terminal device is improved. j j j j

[0187] Exemplarily, the terminal device can also perform an "OR" operation on the HARQ-ACKs of the SPS configurations corresponding to the same HARQ-ACK feedback time unit, that is, as long as at least one SPS PDSCH in the SPS configurations corresponding to the same HARQ-ACK feedback time unit correctly receives data, the terminal device feeds back an ACK. Only when all SPS PDSCHs in the SPS configurations corresponding to the same HARQ-ACK feedback time unit do not correctly receive data, an NACK is fed back.

[0188] For example, as shown in (1) of Figure 16 the SPS PDSCH of SPS configuration 7 carries data, and the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7. Since the terminal device does not correctly receive data on the SPS PDSCHs of the first 4 SPS configurations (there is no data on the SPS PDSCHs of the first four SPS configurations), the terminal device generates a 4-bit HARQ-ACK at the first HARQ-ACK feedback time unit 1001: NACK, NACK, NACK, NACK; since the terminal device does not correctly receive data on the SPS PDSCHs of SPS configuration 5 and SPS configuration 6 and correctly receives data on the SPS PDSCH of SPS configuration 7, a 3-bit HARQ-ACK is generated at the second HARQ-ACK feedback time unit 1002: ACK, ACK, ACK, and the terminal device sends two HARQ-ACKs of two HARQ-ACK feedback time units to the network device: NACK, NACK, NACK, NACK and ACK, ACK, ACK. As shown in Figure 16As shown in (2) of [description], the SPS PDSCH of SPS configuration 4 carries data. The terminal device correctly receives data in the SPS PDSCH of SPS configuration 4, and does not correctly receive data in the SPS PDSCH of the first 3 SPS configurations. Then the terminal device generates 4-bit HARQ-ACK at the first HARQ-ACK feedback time unit 1001: ACK, ACK, ACK, ACK; Since the terminal device does not correctly receive data in the SPS PDSCH of the last 3 SPS configurations, the terminal device generates 3-bit HARQ-ACK at the second HARQ-ACK feedback time unit 1002: NACK, NACK, NACK, and sends two HARQ-ACKs of two HARQ-ACK feedback time units to the network device: ACK, ACK, ACK, ACK and NACK, NACK, NACK.

[0189] In summary, the method provided in this embodiment enables the terminal device to generate n-bit HARQ-ACK at the jth HARQ-ACK feedback time unit according to whether it correctly receives data on the SPS PDSCH of at least one SPS configuration corresponding to the jth HARQ-ACK feedback time unit. If the terminal device correctly receives data, it feeds back n ACKs to the network device through the jth HARQ-ACK feedback time unit. If the terminal device does not receive data, it feeds back n NACKs to the network device through this HARQ-ACK feedback time unit. j bit HARQ-ACK. If the terminal device correctly receives the data, it feeds back n ACKs to the network device through the jth HARQ-ACK feedback time unit. j If the terminal device does not receive the data, it feeds back n NACKs to the network device through this HARQ-ACK feedback time unit. j Thereby improving the reliability of the uplink transmission.

[0190] Exemplary embodiment for the 6th case.

[0191] That is, the SPS configurations of the same HARQ-ACK packet feedback HARQ-ACK through different HARQ-ACK feedback time units, and occupy n-bit feedback information bits in the last HARQ-ACK feedback time unit, and only feedback HARQ-ACK in the last HARQ-ACK feedback time unit, where n is the number of SPS configurations corresponding to the last HARQ-ACK feedback time unit. k bit feedback information bits, and only feedback HARQ-ACK in the last HARQ-ACK feedback time unit, where n k is the number of SPS configurations corresponding to the last HARQ-ACK feedback time unit.

[0192] Figure 17 shows a flowchart of a feedback method for semi-persistent scheduling provided by an exemplary embodiment of the present application. This method can be applied to a terminal device in a communication system as shown in Figure 1 As shown, based on Figure 5 the exemplary embodiment shown, before step 406, there is also step 506, and step 406 also includes step 4066:

[0193] There are n activated SPS configurations corresponding to the second HARQ-ACK group; the n SPS configurations of the second HARQ-ACK group correspond to K HARQ-ACK feedback time units, K is a positive integer; the Kth HARQ-ACK feedback time unit corresponds to n k bit feedback information bit, the second HARQ-ACK packet corresponds to n k Bit feedback information bit, n k is the number of SPS configurations corresponding to the Kth HARQ-ACK feedback time unit, n and K are positive integers, n k is a positive integer less than or equal to n; illustratively, the terminal device receives data on the SPS PDSCH corresponding to n SPS configurations, and feeds back HARQ-ACK to the network device within K HARQ-ACK feedback time units corresponding to the n SPS configurations.

[0194] Step 506: The terminal device generates n SPSPDSCHs with the same value according to the reception status of the SPSPDSCHs with effective data transmission on the n SPSPDSCHs corresponding to the n SPS configurations. k bits of HARQ-ACK, n is a positive integer, n k is a positive integer less than or equal to n; or, the terminal device generates n SPSs with the same value according to the logical OR result of the reception conditions on the n SPSPDSCHs corresponding to the n SPS configurations. k bits of HARQ-ACK, n is a positive integer, n k is a positive integer less than or equal to n.

[0195] Step 4066: The terminal device receives data on at least one SPS PDSCH corresponding to the n SPS configurations, and feeds back the nth time unit of the Kth HARQ-ACK corresponding to the n SPS configurations. k The bit feedback information bit feeds back HARQ-ACK to the network device.

[0196] For example, Figure 18As shown in the figure, the network device divides 7 SPS configurations into the same HARQ-ACK group. Then n is 7, and the SPS configurations in this group correspond to two HARQ-ACK feedback time units: the first HARQ-ACK feedback time unit 1001 and the second HARQ-ACK feedback time unit 1002, that is, K is 2. Among them, SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4 correspond to the first HARQ-ACK feedback time unit 1001; SPS configuration 5, SPS configuration 6, and SPS configuration 7 correspond to the second HARQ-ACK feedback time unit 1002. That is, 4 SPS configurations corresponding to the first HARQ-ACK feedback time unit; 3 SPS configurations corresponding to the second HARQ-ACK feedback time unit. The terminal device only uses 3-bit HARQ-ACK in the second HARQ-ACK feedback time unit to feedback to the network device the data reception situation on the SPS PDSCH of the 7 SPS configurations.

[0197] Exemplarily, the terminal device determines the HARQ-ACK on the Kth HARQ-ACK feedback time unit (the last HARQ-ACK feedback time unit) according to the data reception situation in the n SPS configurations of a HARQ-ACK group. If the terminal device correctly receives data on at least one SPS PDSCH among the n SPS configurations, the terminal device feedbacks n k bits of HARQ-ACK: n k ACKs to indicate correct data reception. If the terminal device does not correctly receive data on the SPS PDSCH of the n SPS configurations, the terminal device feedbacks n k bits of HARQ-ACK: n k NACKs to indicate that the data has not been correctly received. Thus, the reliability of the uplink transmission is improved.

[0198] Exemplarily, the terminal device can also take the "OR" of the HARQ-ACKs of the SPS configurations in the same HARQ-ACK group, that is, as long as the data is correctly received on at least one SPS PDSCH in the SPS configurations of the same HARQ-ACK group, the terminal device feedbacks ACK. Only when all SPS PDSCHs in the SPS configurations of the same HARQ-ACK group have not been correctly received, NACK is feedback.

[0199] For example, as Figure 18As shown in (1) therein, the SPS PDSCH of SPS configuration 7 carries data, and the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7. If the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 7 and does not correctly receive the data in the SPS PDSCHs of the other 6 SPS configurations, the terminal device generates 3-bit HARQ-ACK: ACK, ACK, ACK at the second HARQ-ACK feedback time unit 1002 and sends the HARQ-ACK: ACK, ACK, ACK to the network device. As Figure 14 As shown in (2) therein, the SPS PDSCH of SPS configuration 4 carries data, and the terminal device correctly receives the data in the SPS PDSCH of SPS configuration 4 and does not correctly receive the data in the SPS PDSCHs of the other 6 SPS configurations. Then the terminal device generates 3-bit HARQ-ACK: ACK, ACK, ACK at the second HARQ-ACK feedback time unit 1002 and sends the HARQ-ACK: ACK, ACK, ACK to the network device.

[0200] In summary, the method provided in this embodiment enables the terminal device to generate n k bit HARQ-ACK at the last HARQ-ACK feedback time unit according to whether the data is correctly received on the SPS PDSCH of the SPS configuration in the same HARQ-ACK packet. If the terminal device correctly receives the data, it feeds back n k ACKs to the network device through the last HARQ-ACK feedback time unit. If the terminal device does not correctly receive the data, it feeds back n k NACKs to the network device through the last HARQ-ACK feedback time unit, thereby improving the reliability of the uplink transmission.
