Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a HARQ feedback method and apparatus thereof. Background Art

[0002] In the research of wireless communication technologies, satellite communication is considered an important aspect of the future development of wireless communication technologies. Satellite communication refers to the communication in which radio communication devices on the ground use satellites as relays. However, due to the long signal transmission distance in the satellite communication scenario, there is a relatively large delay in data transmission. This relatively large delay may cause a hybrid automatic repeat request (HARQ) delay problem, that is, the network device needs to wait for the HARQ feedback of the downlink transmission from the terminal device before it can perform subsequent downlink transmissions. However, due to this relatively large delay, the network device waits for a long time and the subsequent downlink transmissions are blocked.

[0003] To solve the HARQ delay problem, in related technologies, if the network device schedules a transport block through a scheduling instruction, the terminal device can determine whether to send HARQ feedback based on whether the HARQ process of the transport block is in an unenabled state. Correspondingly, for the network device, since the HARQ process of the transport block can be in an unenabled state, it can at least avoid the network device waiting for the HARQ feedback in the unenabled state. However, in related technologies, for the case where the scheduling instruction schedules multiple transport blocks, there is still no clear HARQ feedback method. Summary of the Invention

[0004] Embodiments of the present disclosure provide a HARQ feedback method and apparatus thereof, which can be applied to a terrestrial network and a non-terrestrial network. The non-terrestrial network includes the Internet of Things (IoT) based on satellite communication, such as the narrow band Internet of Things (NB-IoT); the vehicle-to-everything (V2X) network, such as vehicle-to-everything (V2X) communication, long term evolution-vehicle (LTE-V) for vehicle-to-vehicle communication, vehicle-to-vehicle (V2V) communication, etc., or can be used in fields such as intelligent driving and intelligent connected vehicles. It is used to solve the problem of how to perform HARQ feedback when the scheduling instruction of the network device schedules multiple transport blocks.

[0005] In a first aspect, embodiments of the present disclosure provide a HARQ feedback method, which is executed by a terminal device and includes:

[0006] Receive a scheduling instruction sent by a network device, where the scheduling instruction is used to schedule a plurality of transport blocks;

[0007] In response to the plurality of transport blocks including a first transport block enabling HARQ feedback and a second transport block not enabling HARQ feedback, send at least one HARQ feedback to the network device;

[0008] Wherein, the at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0009] In this technical solution, after the terminal device receives the information carried by the plurality of transport blocks scheduled by the same scheduling instruction, it can send the corresponding HARQ feedback to the network device only for the first transport block enabling HARQ feedback among the plurality of transport blocks. In this way, it can be avoided that the network device waits until all the HARQ feedbacks corresponding to all the transport blocks among the plurality of transport blocks are received and then performs subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0010] In one implementation, the at least one HARQ feedback further includes:

[0011] The HARQ feedback corresponding to the second transport block.

[0012] In one implementation, the HARQ information included in the HARQ feedback corresponding to the second transport block is one of the following HARQ information:

[0013] The HARQ information used to determine whether the information carried by the second transport block is successfully received;

[0014] The HARQ information of a set value.

[0015] In this technical solution, after the terminal device receives the information carried by the plurality of transport blocks scheduled by the same scheduling instruction, it can send the corresponding HARQ feedback to the network device for the first transport block enabling HARQ feedback among the plurality of transport blocks. The network device can wait for the HARQ feedback for the second transport block or can perform subsequent transmissions without waiting for the HARQ feedback for the second transport block. In this way, it can be avoided that the network device waits until all the HARQ feedbacks corresponding to all the transport blocks among the plurality of transport blocks are received and then performs subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0016] In one implementation, the method further includes:

[0017] Receive the indication information sent by the network device;

[0018] Wherein, the indication information is used to determine whether at least one transport block among the multiple transport blocks is the first transport block or the second transport block.

[0019] In one implementation, the method further includes:

[0020] Based on the configuration information agreed upon by the protocol, determine that at least one transport block among the multiple transport blocks is the first transport block or the second transport block.

[0022] In response to only the second transport blocks that do not enable HARQ feedback being included among the multiple transport blocks, do not send HARQ feedback corresponding to any of the second transport blocks to the network device.

[0023] In this technical solution, after the terminal device receives the information carried by the multiple transport blocks scheduled by the same scheduling instruction, if only the second transport blocks that do not enable HARQ feedback are included among the multiple transport blocks, then do not send HARQ feedback corresponding to any of the second transport blocks to the network device. Correspondingly, the network device does not need to wait until HARQ feedback corresponding to all the transport blocks among the multiple transport blocks is received, and then perform subsequent transmissions. In this way, it is possible to avoid the network device waiting until HARQ feedback corresponding to all the transport blocks among the multiple transport blocks is received, and then perform subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0024] In one implementation, the method further includes:

[0025] In response to only the first transport blocks that enable HARQ feedback being included among the multiple transport blocks, send HARQ feedback corresponding to at least one of the first transport blocks to the network device.

[0026] In this technical solution, after the terminal device receives the information carried by the multiple transport blocks scheduled by the same scheduling instruction, if only the first transport blocks that enable HARQ feedback are included among the multiple transport blocks, then send HARQ feedback corresponding to at least one of the first transport blocks to the network device. Correspondingly, after the network device receives HARQ feedback corresponding to at least one transport block among the multiple transport blocks, it can perform subsequent transmissions. In this way, it is possible to avoid the network device having to wait until HARQ feedback corresponding to all the transport blocks among the multiple transport blocks is received, and then perform subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0031] In this technical solution, after the network device sends the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device, it can wait to receive the corresponding HARQ feedback sent by the terminal device only for the first transport block enabling HARQ feedback among the plurality of transport blocks. In this way, it can be avoided that the network device waits until all the HARQ feedbacks corresponding to all the transport blocks among the plurality of transport blocks are received and then performs subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

The network device can wait for the HARQ feedback for the second transport block, or can perform subsequent transmissions without waiting for the HARQ feedback for the second transport block. In this way, it can be avoided that the network device waits until all the HARQ feedbacks corresponding to all the transport blocks among the plurality of transport blocks are received and then performs subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0042] In response to only the second transport block that does not enable HARQ feedback being included among the multiple transport blocks, there is no need to wait for the HARQ feedback corresponding to any of the second transport blocks sent by the terminal device.

That is to say, the network device does not need to wait until the HARQ feedback corresponding to all the transport blocks among the multiple transport blocks is received before performing subsequent transmissions. In this way, it is possible to avoid the network device waiting until the HARQ feedback corresponding to all the transport blocks among the multiple transport blocks is received before performing subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0044] In one implementation, the method may further include:

[0118] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present disclosure as detailed in the appended claims.

[0119] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0120] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "when" as used herein may be interpreted as "when" or "when" or "in response to a determination".

[0121] For ease of understanding, the terms related to the present disclosure are first introduced.

[0122] 1. Downlink Control Information (DCI)

[0123] DCI is carried by the Physical Downlink Control Channel (PDCCH). DCI may include uplink and downlink resource allocation, HARQ feedback, power control, etc. The PDCCH is a physical channel used to carry downlink control information.

[0124] 2. HARQ Feedback

[0125] The HARQ protocol is one of the most important features in a cellular communication system. The feedback information of HARQ feedback may be HARQ acknowledgement (ACK) feedback, or it may be HARQ negative acknowledgement (NACK) feedback. Using the HARQ protocol, the network device needs to wait for feedback from the terminal device before sending new data. In the case of NACK, the network device may need to re - send the data packet. Otherwise, the network device can send new data. This stop - and - wait process introduces an inherent delay to the communication protocol, which may reduce the link throughput.

[0126] To solve the HARQ delay problem, in the related art, if the network device schedules a transport block through a scheduling instruction, the terminal device can determine whether to send HARQ feedback based on whether the HARQ process of the transport block is in an un - enabled state. Correspondingly, for the network device, since the HARQ process of the transport block can be in an un - enabled state, it can at least avoid the network device waiting for HARQ feedback in the un - enabled state. However, in the related art, for the case where a scheduling instruction schedules multiple transport blocks, there is still a lack of a clear HARQ feedback method.

[0127] To better understand a HARQ feedback method disclosed in an embodiment of the present disclosure, the communication system applicable to the embodiment of the present disclosure is first described below.

[0128] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of the devices shown are only for illustration and do not constitute a limitation on the embodiments of the present disclosure. In practical applications, there may be two or more network devices and two or more terminal devices. Figure 1The illustrated communication system takes a network device 101 and a terminal device 102 as an example.

[0129] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems. For example: Long Term Evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems, etc.

[0130] The network device 101 in the embodiments of the present disclosure is an entity on the network side for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (WiFi) system, etc. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device. The network device provided by the embodiments of the present disclosure can be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU can also be called a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0131] The terminal device 102 in the embodiments of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device may be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the terminal device.

[0132] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly explaining the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0133] In order to clearly illustrate the HARQ feedback method of the terminal device in the case where multiple transport blocks are scheduled based on the scheduling instructions of the network device in the foregoing communication system, the HARQ feedback method and its device provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0134] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a HARQ feedback method provided by an embodiment of the present disclosure. As Figure 2 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0135] Step 201, receive a scheduling instruction sent by the network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0136] In all embodiments of the present disclosure, multiple transport blocks are scheduled by the same scheduling instruction.

[0137] The network device schedules the transmission of multiple transport blocks by means of a scheduling instruction, so that the terminal device correspondingly receives the information carried by the multiple transport blocks on the multiple transmission resources scheduled by the scheduling instruction. Then, after the terminal device receives the information carried by the multiple transport blocks, the terminal device can determine whether HARQ feedback is required for the multiple transport blocks, and / or determine the HARQ information for HARQ feedback. In the embodiments of the present disclosure, "multiple" means two or more.

[0138] For example: For the terminal device of NB-IoT, the network device can schedule the unicast transport blocks of multiple Narrowband Physical Downlink Shared Channels (NPDSCH) through the Narrowband Physical Downlink Control Channel (NPDCCH). In an example where the network device schedules the unicast transport blocks of two NPDSCH channels, the scheduled transport blocks can be denoted as Transport Block (TB) 1 and TB2. When the terminal device correspondingly receives the information carried by the transport blocks TB1 and TB2 on the transmission resources of the transport blocks TB1 and TB2 scheduled by the scheduling instruction, and then after the terminal device receives the information carried by the transport blocks TB1 and TB2, it determines whether to send the corresponding HARQ feedback for TB1 and TB2 respectively. The specific steps for HARQ feedback will be described in subsequent steps and will not be elaborated herein.

[0139] It should be noted that the network device can send the scheduling instruction based on DCI signaling, or send the scheduling instruction based on high-layer signaling such as Radio Resource Control (RRC), or send the scheduling instruction based on physical layer signaling such as Mobile Edge Computing (MEC) Customer Edge (CE). This is not limited in this embodiment.

[0140] Step 202: In response to the fact that the multiple transport blocks include a first transport block enabling HARQ feedback and a second transport block not enabling HARQ feedback, send at least one HARQ feedback to the network device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0141] The network device transmits information through a first transport block and a second transport block. After the terminal device receives the information carried by the first transport block and the second transport block from the network device, it decodes the information carried by the received first transport block and the second transport block respectively to determine whether the information carried by the first transport block and the second transport block has been correctly received.

[0142] For the first transport block, if the terminal device correctly receives the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the first transport block according to whether the HARQ information of the HARQ feedback corresponding to the first transport block sent by the terminal device is ACK or NACK.

[0143] For the second transport block, since it is a second transport block without HARQ feedback enabled, regardless of whether the terminal device correctly receives the information carried by the second transport block, it does not need to send the HARQ feedback corresponding to the second transport block to the network device. That is, in step 202, in response to the multiple transport blocks including the first transport block with HARQ feedback enabled and the second transport block without HARQ feedback enabled, at least one HARQ feedback is sent to the network device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and does not include the HARQ feedback corresponding to the second transport block.

[0144] As Figure 3 shown, the schematic diagram describes that in the case where two transport blocks are scheduled by the same scheduling instruction, the terminal device receives the TB1 transmission and the TB2 transmission based on the downlink channel (DL). Among them, the transport block TB1 used for the TB1 transmission is the first transport block with HARQ feedback enabled, and the transport block TB2 used for the TB2 transmission is the second transport block without HARQ feedback enabled. As Figure 3 shown, the terminal device can transmit the HARQ feedback for the transport block TB1 in the uplink channel (UL) without transmitting the HARQ feedback for the transport block TB2. Correspondingly, after the network device transmits the TB1 transmission and the TB2 transmission based on the downlink channel, it only needs to wait to receive the HARQ feedback for the transport block TB1 from the terminal device, without waiting for the HARQ feedback for the transport block TB2, and then can perform subsequent transmissions, thereby reducing the transmission delay caused by waiting to a certain extent.

[0145] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, it may send the corresponding HARQ feedback to the network device only for the first transport block that enables HARQ feedback among the multiple transport blocks. In this way, it is possible to avoid the network device waiting until all the HARQ feedbacks corresponding to all the transport blocks among the multiple transport blocks are received and then performing subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0146] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 4 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0147] Step 401: Receive a scheduling instruction sent by the network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0148] Referring to the relevant descriptions in the foregoing embodiments, they will not be elaborated in this embodiment.

[0149] Step 402: In response to the first transport block that enables HARQ feedback and the second transport block that does not enable HARQ feedback among the multiple transport blocks, send at least one HARQ feedback to the network device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and the HARQ feedback corresponding to the second transport block.

[0150] The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the first transport block and the second transport block of the network device, the terminal device decodes the information carried by the first transport block and the information carried by the second transport block respectively to determine whether the information carried by the first transport block and the information carried by the second transport block are correctly received.

[0151] For the first transport block, if the terminal device correctly receives the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the first transport block according to whether the HARQ information of the HARQ feedback corresponding to the first transport block sent by the terminal device is ACK or NACK.

[0152] For the second transmission block, as a first possible implementation method, the HARQ information contained in the HARQ feedback corresponding to the second transmission block is HARQ information used to determine whether the information carried by the second transmission block is received successfully. If the terminal device correctly receives the information carried by the second transmission block, the HARQ information contained in the HARQ feedback corresponding to the second transmission block is ACK; if the terminal device does not correctly receive the information carried by the second transmission block, the HARQ information contained in the HARQ feedback corresponding to the second transmission block is NACK. Accordingly, the network device determines whether the terminal device has correctly received the information carried by the second transmission block based on whether the HARQ information of the HARQ feedback corresponding to the second transmission block sent by the terminal device is ACK or NACK. The network device can wait for the HARQ feedback for the second transmission block, or it can perform subsequent transmission without waiting for the HARQ feedback for the second transmission block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0153] For the second transmission block, as a second possible implementation method, the HARQ information in the HARQ feedback corresponding to the second transmission block is a default value. That is to say, regardless of whether the terminal device correctly receives the information carried by the second transmission block, the HARQ information contained in the HARQ feedback corresponding to the second transmission block is the same default value, and this default value can be ACK or NACK for example. Accordingly, the network device cannot determine whether the terminal device has correctly received the information carried by the second transmission block based on the HARQ information of the HARQ feedback corresponding to the second transmission block sent by the terminal device. Therefore, the network device can perform subsequent transmission without waiting for the HARQ feedback for the second transmission block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0154] like Figure 5 As shown in FIG, the diagram describes that when two transmission blocks are scheduled by the same scheduling instruction, the terminal device receives TB1 transmission and TB2 transmission based on the downlink channel (DL). Among them, the transmission block TB1 used for TB1 transmission is the first transmission block with HARQ feedback enabled, and the transmission block TB2 used for TB2 transmission is the second transmission block without HARQ feedback enabled. Figure 5As shown in the figure, the terminal device may transmit HARQ feedback for transport block TB1 in the uplink channel (UL), and transmit HARQ feedback for transport block TB2. Accordingly, after the network device transmits TB1 transmission and TB2 transmission based on the downlink channel, it needs to wait to receive the HARQ feedback from the terminal device for transport block TB1. After receiving the HARQ feedback for transport block TB1, the network device may wait for the HARQ feedback for transport block TB2, or may perform subsequent transmissions without waiting for the HARQ feedback for transport block TB2, thereby reducing the transmission delay caused by waiting to a certain extent.

[0155] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, it may send corresponding HARQ feedback to the network device for the first transport block that enables HARQ feedback among the multiple transport blocks. The network device may wait for the HARQ feedback for the second transport block, or may perform subsequent transmissions without waiting for the HARQ feedback for the second transport block. In this way, it is possible to prevent the network device from waiting until all the HARQ feedbacks corresponding to all the transport blocks among the multiple transport blocks are received before performing subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0156] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 6 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0157] Step 601: Receive a scheduling instruction sent by the network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0158] Referring to the relevant descriptions in the foregoing embodiments, details are not described herein again.

[0159] Step 602: In response to that only the second transport blocks that do not enable HARQ feedback are included among the multiple transport blocks, do not send the HARQ feedback corresponding to any of the second transport blocks to the network device.

[0160] The network device transmits information through a second transport block. After the terminal device receives the information carried by the network device through the second transport block, the terminal device decodes the information carried by each second transport block respectively to determine whether the information carried by each second transport block is correctly received. For each second transport block, regardless of whether the terminal device correctly receives the information carried by each second transport block, the terminal device does not send HARQ feedback corresponding to any second transport block to the network device. Therefore, the network device can perform subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0161] As Figure 7 shown, the schematic diagram describes that when two transport blocks are scheduled by the same scheduling instruction, the terminal device receives TB1 transmission and TB2 transmission based on the downlink channel (DL). Among them, the transport block TB1 used for TB1 transmission and the transport block TB2 used for TB2 transmission are both second transport blocks for which HARQ feedback is not enabled. As Figure 7 shown, the terminal device may not send any HARQ feedback in the uplink channel (UL), that is, it does not send HARQ feedback for the transport block TB1 and does not send HARQ feedback for the transport block TB2. Accordingly, after the network device transmits the transport block TB1 and the transport block TB2 based on the downlink channel, it can perform subsequent transmissions without waiting to receive HARQ feedback from the terminal device for the transport blocks TB1 and TB2, thereby reducing the transmission delay caused by waiting to a certain extent.

[0162] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, if only second transport blocks for which HARQ feedback is not enabled are included in the multiple transport blocks, the terminal device does not send HARQ feedback corresponding to any second transport block to the network device. Accordingly, the network device can perform subsequent transmissions without waiting until HARQ feedback corresponding to all transport blocks in the multiple transport blocks is received. In this way, it is possible to avoid the network device waiting until HARQ feedback corresponding to all transport blocks in the multiple transport blocks is received before performing subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0163] Please refer to Figure 8 , Figure 8 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 8 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0164] Step 801: Receive a scheduling instruction sent by a network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0165] Referring to the relevant descriptions in the foregoing embodiments, they will not be elaborated herein.

[0166] Step 802: In response to only the first transport block enabling HARQ feedback among the multiple transport blocks, send HARQ feedback corresponding to at least one first transport block to the network device.

[0167] The network device transmits information through the first transport block. After the terminal device receives the information carried by the first transport block from the network device, the terminal device decodes the information carried by each first transport block respectively to determine whether the information carried by each first transport block is correctly received.

[0168] For each first transport block, the terminal device may send HARQ feedback corresponding to only one first transport block among the multiple first transport blocks to the network device, or may also send corresponding HARQ feedback to the network device for each first transport block.

[0169] As a possible implementation, the terminal device only sends HARQ feedback corresponding to one first transport block among the multiple first transport blocks to the network device. The HARQ information of the HARQ feedback sent by the terminal device may be determined based on whether the information carried by the multiple first transport blocks is correctly received. For example: when the information carried by all the multiple first transport blocks is correctly received, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network may be ACK; when there is at least one transport block among the multiple first transport blocks whose carried information is not correctly received, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network may be NACK.

[0170] As another possible implementation, the terminal device sends corresponding HARQ feedback for each first transport block among the multiple first transport blocks to the network device. The HARQ information of the HARQ feedback sent by the terminal device may be determined based on whether the information carried by the corresponding first transport block is correctly received.

[0171] As Figure 9 shown, the schematic diagram describes the situation where the terminal device receives TB1 transmission and TB2 transmission based on the downlink channel (DL) when two transport blocks are scheduled by the same scheduling instruction. Among them, the transport block TB1 used for TB1 transmission and the transport block TB2 used for TB2 transmission are both first transport blocks enabling HARQ feedback. The terminal device may send HARQ feedback for at least one transport block in the uplink channel (UL). For example: as Figure 9As shown, HARQ feedback can be sent for both transport block TB1 and transport block TB2. Correspondingly, after the network device transmits transport block TB1 and transport block TB2 based on the downlink channel, it can wait to receive HARQ feedback for at least one of the transport blocks TB1 and TB2, without waiting to receive HARQ feedback from the terminal device for the remaining transport blocks among TB1 and TB2, and then can perform subsequent transmissions, thereby reducing the transmission delay caused by waiting to a certain extent.

[0172] It should be noted that those skilled in the art can understand that the network device can also wait to receive HARQ feedback for all of the transport blocks among TB1 and TB2 before performing subsequent transmissions, and this embodiment does not limit this.

[0173] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, if only the first transport block that enables HARQ feedback is included among the multiple transport blocks, it sends HARQ feedback corresponding to at least one first transport block to the network device. Correspondingly, after the network device receives HARQ feedback corresponding to at least one of the multiple transport blocks, it can perform subsequent transmissions. In this way, it can be avoided that the network device must wait to receive HARQ feedback corresponding to all of the multiple transport blocks before performing subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0174] Please refer to Figure 10 , Figure 10 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 10 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0175] Step 1001: Receive indication information sent by the network device, where the indication information is used to determine whether at least one of the multiple transport blocks is a first transport block that enables HARQ feedback or a second transport block that does not enable HARQ feedback.

[0176] In an embodiment of the present disclosure, in one possible implementation, it may be indicated whether each transport block enables HARQ feedback or does not enable HARQ feedback. In another possible implementation, it may be default that the transport block enables HARQ feedback, and the network device indicates the transport blocks that do not enable HARQ feedback. In yet another possible implementation, it may be default that the transport block does not enable HARQ feedback, and the network device indicates the transport blocks that enable HARQ feedback. The network device sends this indication information based on high-layer signaling such as RRC, or based on physical-layer signaling such as MEC CE, or the network device sends this indication information based on DCI signaling. This is not limited in this embodiment.

[0177] As a possible implementation, this indication information is used to indicate multiple available transport blocks between the network device and the terminal device. The signaling for sending this indication information also carries an indication field, which may be newly added or may reuse an existing indication field. The terminal device determines, according to this indication field, whether at least one transport block among the multiple transport blocks is a first transport block that enables HARQ feedback or a second transport block that does not enable HARQ feedback.

[0178] The network device enables the terminal device to determine multiple available transport blocks between the network device and the terminal device, and whether the multiple transport blocks are the first transport block or the second transport block, so that the network device selects at least some of the transport blocks from the multiple available transport blocks for scheduling through a scheduling instruction.

[0179] Those skilled in the art may be aware that the indication information for indicating whether multiple transport blocks are the first transport block or the second transport block may be sent through multiple signaling. For example: each signaling indicates whether at least one transport block is the first transport block or the second transport block; the indication information may also be sent through one signaling. For example: this indication information is sent through one signaling, indicating whether each of the multiple transport blocks is the first transport block or the second transport block.

[0180] Step 1002, receive a scheduling instruction sent by the network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0181] Step 1003, in response to the multiple transport blocks including a first transport block that enables HARQ feedback and a second transport block that does not enable HARQ feedback, send at least one HARQ feedback to the network device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0182] For the specific descriptions of step 1002 and step 1003, refer to the relevant descriptions in the foregoing embodiments. This is not elaborated in this embodiment.

[0183] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, it can send the corresponding HARQ feedback to the network device only for the first transport block that enables HARQ feedback among the multiple transport blocks. In this way, it can be avoided that the network device waits until the HARQ feedback corresponding to all transport blocks among the multiple transport blocks is received and then proceeds with subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0184] Please refer to Figure 11 , Figure 11 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 10 shown, this method is executed by the terminal device, and this method may include but is not limited to the following steps:

[0185] Step 1101: Based on the configuration information agreed upon by the protocol, determine that at least one transport block among the multiple transport blocks is the first transport block or the second transport block.

[0186] As a possible implementation, in the configuration information agreed upon by the protocol, multiple transport blocks available between the network device and the terminal device are agreed upon, and whether the multiple transport blocks are the first transport block or the second transport block. So that the network device selects at least some of the transport blocks from the agreed available multiple transport blocks for scheduling through a scheduling instruction.

[0187] Step 1102: Receive the scheduling instruction sent by the network device, where the scheduling instruction is used to schedule the transmission of multiple transport blocks.

[0188] Step 1103: In response to the first transport block that enables HARQ feedback and the second transport block that does not enable HARQ feedback being included among the multiple transport blocks, send at least one HARQ feedback to the network device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0189] For the specific details of Step 1102 and Step 1103, please refer to the relevant descriptions in the foregoing embodiments, and they will not be elaborated in this embodiment.

[0190] By implementing the embodiments of the present disclosure, after the terminal device receives the information carried by multiple transport blocks scheduled by the same scheduling instruction, it can send the corresponding HARQ feedback to the network device only for the first transport block that enables HARQ feedback among the multiple transport blocks. In this way, it can be avoided that the network device waits until the HARQ feedback corresponding to all transport blocks among the multiple transport blocks is received and then proceeds with subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0191] Those skilled in the art can understand that the foregoing multiple embodiments executed by the terminal device can be implemented independently or in any combination, and the embodiments of the present disclosure do not limit this.

[0192] Please refer to Figure 12 , Figure 12 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 12 shown, this method is executed by a network device, and this method may include but is not limited to the following steps:

[0193] Step 1201: Send a scheduling instruction to the terminal device, where the scheduling instruction is used to schedule multiple transport blocks.

[0194] The network device may send a scheduling instruction to the terminal device. Among them, the scheduling instruction is used to schedule the transmission of multiple transport blocks. It can be understood that since the network device can schedule the transmission of multiple transport blocks in the scheduling instruction, the terminal device can correspondingly receive the information carried by multiple transport blocks on multiple transport resources scheduled by the scheduling instruction. Furthermore, after the terminal device receives the information carried by multiple transport blocks, the terminal device can determine whether HARQ feedback is required for these multiple transport blocks and / or determine the HARQ information of the HARQ feedback.

[0195] It should be noted that the network device may send this scheduling instruction based on DCI signaling, or based on high-layer signaling such as RRC, or based on physical layer signaling such as MEC CE. This is not limited in this embodiment.

[0196] Step 1202: If the multiple transport blocks include a first transport block that enables HARQ feedback and a second transport block that does not enable HARQ feedback, then wait to receive at least one HARQ feedback sent by the terminal device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0197] The network device transmits information through the first transport block and the second transport block. After the terminal device receives the information carried by the first transport block and the second transport block of the network device, it will respectively decode the information carried by the received first transport block and the information carried by the second transport block to determine whether the information carried by the first transport block and the information carried by the second transport block are correctly received, and send HARQ feedback to the network device so that the network device can continue subsequent transmissions after receiving the HARQ feedback sent by the terminal device.

[0198] For the first transport block, the terminal device may send HARQ information corresponding to the HARQ feedback of the first transport block to the network device based on whether the information carried by the first transport block and the information carried by the second transport block are correctly received. Specifically, if the terminal device correctly receives the information carried by the first transport block, the HARQ information corresponding to the HARQ feedback of the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, the HARQ information corresponding to the HARQ feedback of the first transport block is NACK. Correspondingly, the network device may wait to receive the HARQ information corresponding to the HARQ feedback of the first transport block sent by the terminal device, and determine whether the terminal device has correctly received the information carried by the first transport block according to whether the HARQ information is ACK or NACK.

[0199] For the second transport block, since it is a second transport block for which HARQ feedback is not enabled, the terminal device does not need to send HARQ feedback corresponding to the second transport block to the network device regardless of whether the terminal device correctly receives the information carried by the second transport block. Correspondingly, the network device also does not need to wait to receive the HARQ feedback corresponding to the second transport block sent by the terminal device. That is, in step 1202, in response to the plurality of transport blocks including the first transport block for which HARQ feedback is enabled and the second transport block for which HARQ feedback is not enabled, wait to receive at least one HARQ feedback sent by the terminal device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and does not include the HARQ feedback corresponding to the second transport block.

[0200] By implementing the embodiments of the present disclosure, after the network device sends the information carried by the plurality of transport blocks scheduled by the scheduling instruction to the terminal device, it can wait to receive the corresponding HARQ feedback sent by the terminal device only for the first transport block for which HARQ feedback is enabled among the plurality of transport blocks. In this way, it is possible to avoid the network device waiting until all the HARQ feedbacks corresponding to all the transport blocks among the plurality of transport blocks are received and then performing subsequent transmissions, thereby helping to reduce the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0201] Please refer to Figure 13 , Figure 13 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 13 shown, this method is executed by the network device, and this method may include but is not limited to the following steps:

[0202] Step 1301: Send a scheduling instruction to the terminal device, where the scheduling instruction is used to schedule a plurality of transport blocks.

[0203] Referring to the relevant descriptions in the foregoing embodiments, details are not described herein again in this embodiment.

[0204] Step 1302: In response to the first transport block enabling HARQ feedback and the second transport block disabling HARQ feedback among multiple transport blocks, wait for at least one HARQ feedback sent by the receiving terminal device, where the at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block and the HARQ feedback corresponding to the second transport block.

[0205] The network device transmits information through the first transport block and the second transport block. After receiving the information carried by the first transport block and the second transport block from the network device, the terminal device decodes the information carried by the received first transport block and the second transport block respectively to determine whether the information carried by the first transport block and the second transport block has been correctly received, and sends HARQ feedback to the network device, so that the network device can continue subsequent transmissions after receiving the HARQ feedback sent by the terminal device.

[0206] For the first transport block, the terminal device can send HARQ information of the HARQ feedback corresponding to the first transport block to the network device based on whether the information carried by the first transport block and the second transport block has been correctly received. Specifically, if the terminal device correctly receives the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is ACK; if the terminal device does not correctly receive the information carried by the first transport block, the HARQ information of the HARQ feedback corresponding to the first transport block is NACK. Correspondingly, the network device can wait to receive the HARQ information of the HARQ feedback corresponding to the first transport block sent by the terminal device, and determine whether the terminal device has correctly received the information carried by the first transport block based on whether the HARQ information is ACK or NACK.

[0207] For the second transport block, as a first possible implementation, the HARQ information included in the HARQ feedback corresponding to the second transport block is the HARQ information used to determine whether the information carried by the second transport block has been successfully received. If the terminal device correctly receives the information carried by the second transport block, the HARQ information included in the HARQ feedback corresponding to the second transport block is ACK; if the terminal device does not correctly receive the information carried by the second transport block, the HARQ information included in the HARQ feedback corresponding to the second transport block is NACK. Correspondingly, the network device determines whether the terminal device has correctly received the information carried by the second transport block based on whether the HARQ information of the HARQ feedback corresponding to the second transport block sent by the terminal device is ACK or NACK. It should be noted that the network device can wait for the HARQ feedback for the second transport block, or can perform subsequent transmissions without waiting for the HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0208] For the second transport block, as a second possible implementation, the HARQ information in the HARQ feedback corresponding to the second transport block is a default value. That is, regardless of whether the terminal device correctly receives the information carried by the second transport block, the HARQ information included in the HARQ feedback corresponding to the second transport block is the same default value, which can be, for example, ACK or NACK. Accordingly, the network device cannot determine whether the terminal device has correctly received the information carried by the second transport block based on the HARQ information in the HARQ feedback corresponding to the second transport block sent by the terminal device. Therefore, the network device can perform subsequent transmissions without waiting for the HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0209] By implementing the embodiments of the present disclosure, after the network device sends the information carried by multiple transport blocks scheduled by the scheduling instruction to the terminal device, it can wait to receive the corresponding HARQ feedback sent by the terminal device only for the first transport block that enables HARQ feedback among the multiple transport blocks. The network device can wait for the HARQ feedback for the second transport block, or can perform subsequent transmissions without waiting for the HARQ feedback for the second transport block. In this way, it is possible to prevent the network device from waiting until all the HARQ feedbacks corresponding to all the transport blocks among the multiple transport blocks are received before performing subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for the HARQ feedback to a certain extent.

[0210] Please refer to Figure 14 , Figure 14 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 14 shown, this method is executed by the network device, and this method may include but is not limited to the following steps:

[0211] Step 1401: Send a scheduling instruction to the terminal device, where the scheduling instruction is used to schedule multiple transport blocks.

[0212] Referring to the relevant descriptions in the foregoing embodiments, details are not described again in this embodiment.

[0213] Step 1402: In response to that only the second transport block that does not enable HARQ feedback is included among the multiple transport blocks, do not wait to receive the HARQ feedback corresponding to any of the second transport blocks sent by the terminal device.

[0214] The network device transmits information through a second transport block. After the terminal device receives the information carried by the network device through the second transport block, it decodes the information carried by each received second transport block respectively to determine whether the information carried by each second transport block is correctly received. For each second transport block, regardless of whether the terminal device correctly receives the information carried by each second transport block, the terminal device does not send HARQ feedback corresponding to any second transport block to the network device. Therefore, the network device can perform subsequent transmissions without waiting for HARQ feedback for the second transport block, thereby reducing the transmission delay caused by waiting to a certain extent.

[0215] By implementing the embodiments of the present disclosure, after the network device sends the information carried by multiple transport blocks scheduled by a scheduling instruction to the terminal device, if only the second transport block that does not enable HARQ feedback is included in the multiple transport blocks, it does not need to wait for the HARQ feedback corresponding to any second transport block sent by the terminal device. That is to say, the network device does not need to wait until the HARQ feedback corresponding to all transport blocks in the multiple transport blocks is received before performing subsequent transmissions. In this way, it can be avoided that the network device waits until the HARQ feedback corresponding to all transport blocks in the multiple transport blocks is received before performing subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0216] Please refer to Figure 15 , Figure 15 is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 15 shown, this method is executed by the network device, and this method may include but is not limited to the following steps:

[0217] Step 1501: Send a scheduling instruction to the terminal device, where the scheduling instruction is used to schedule multiple transport blocks.

[0218] Referring to the relevant descriptions in the foregoing embodiments, details are not described herein again.

[0219] Step 1502: In response to only the first transport block that enables HARQ feedback being included in the multiple transport blocks, wait to receive the HARQ feedback corresponding to at least one first transport block sent by the terminal device.

[0220] The network device transmits information through the first transport block. After the terminal device receives the information carried by the network device through the first transport block, it decodes the information carried by each received first transport block respectively to determine whether the information carried by each first transport block is correctly received, and sends HARQ feedback corresponding to at least one first transport block to the network device, so that the network device can continue subsequent transmissions after receiving the HARQ feedback corresponding to at least one transport block among multiple transport blocks.

[0221] For each first transport block, the terminal device may send HARQ feedback corresponding to only one first transport block among multiple first transport blocks to the network device, or may also send HARQ feedback corresponding to each first transport block to the network device.

[0222] As a possible implementation, the terminal device only sends HARQ feedback corresponding to one first transport block among multiple first transport blocks to the network device, so that the network device can wait to receive the HARQ feedback corresponding to this one first transport block sent by the terminal device. Optionally, the HARQ information of the HARQ feedback sent by the terminal device may be determined based on whether the information carried by multiple first transport blocks is correctly received. For example, when the information carried by multiple first transport blocks is correctly received, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network may be ACK; when there is at least one transport block among the information carried by multiple first transport blocks whose information is not correctly received, the HARQ feedback information of the HARQ feedback sent by the terminal device to the network may be NACK.

[0223] As another possible implementation, the terminal device sends HARQ feedback corresponding to each first transport block among multiple first transport blocks to the network device, so that the network device can wait to receive the HARQ feedback corresponding to each first transport block sent by the terminal device. Optionally, the HARQ information of the HARQ feedback sent by the terminal device may be determined based on whether the information carried by the corresponding first transport block is correctly received.

[0224] By implementing the embodiments of the present disclosure, after the network device sends the information carried by multiple transport blocks scheduled by a scheduling instruction to the terminal device, if only the first transport block enabling HARQ feedback is included in the multiple transport blocks, it waits to receive the HARQ feedback corresponding to at least one first transport block sent by the terminal device. That is to say, after the network device receives the HARQ feedback corresponding to at least one transport block among the multiple transport blocks, it can perform subsequent transmissions. In this way, it can be avoided that the network device has to wait until all the HARQ feedbacks corresponding to all the transport blocks among the multiple transport blocks are received before performing subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0225] Please refer to Figure 16 , Figure 16 which is a schematic flowchart of another HARQ feedback method provided by the embodiments of the present disclosure. As Figure 16 shown, this method is executed by the network device, and this method may include but is not limited to the following steps:

[0226] Step 1601: Send indication information to the terminal device, where the indication information is used to determine whether at least one transport block among multiple transport blocks is a first transport block or a second transport block.

[0227] In the embodiments of the present disclosure, in a possible implementation manner, it may be indicated whether each transport block enables HARQ feedback or does not enable HARQ feedback. The network device sends this indication information based on high-layer signaling such as RRC or based on physical-layer signaling such as MECCE, or the network device sends this indication information based on DCI signaling. This is not limited in this embodiment.

[0228] As a possible implementation manner, the indication information is used to indicate multiple transport blocks available between the network device and the terminal device. The signaling for sending this indication information also carries an indication field, which may be a newly added field or a reused existing indication field. The terminal device determines whether at least one transport block among the multiple transport blocks is a first transport block enabling HARQ feedback or a second transport block not enabling HARQ feedback according to this indication field.

[0229] The network device enables the terminal device to determine multiple transport blocks available between the network device and the terminal device, and whether the multiple transport blocks are first transport blocks or second transport blocks, so that the network device selects at least some transport blocks from the available multiple transport blocks for scheduling through a scheduling instruction.

[0230] Those skilled in the art can know that the indication information used to indicate whether multiple transport blocks are the first transport block or the second transport block can be sent through multiple signaling. For example, each signaling indicates whether at least one transport block is the first transport block or the second transport block; the indication information can also be sent through one signaling. For example, the indication information is sent through one signaling, indicating whether each of the multiple transport blocks is the first transport block or the second transport block.

[0231] Step 1602: Send a scheduling instruction to the terminal device, where the scheduling instruction is used to schedule multiple transport blocks.

[0232] Step 1603: In response to the first transport block that enables HARQ feedback and the second transport block that does not enable HARQ feedback being included in the multiple transport blocks, wait to receive at least one HARQ feedback sent by the terminal device, where at least one HARQ feedback includes the HARQ feedback corresponding to the first transport block.

[0233] For the specific details of Step 1602 and Step 1603, please refer to the relevant descriptions in the foregoing embodiments, and they will not be elaborated in this embodiment.

[0234] By implementing the embodiments of the present disclosure, after the network device sends the information carried by the multiple transport blocks scheduled by the scheduling instruction to the terminal device, it can wait to receive the corresponding HARQ feedback sent by the terminal device only for the first transport block that enables HARQ feedback among the multiple transport blocks. In this way, it can be avoided that the network device waits until all the HARQ feedbacks corresponding to all the transport blocks among the multiple transport blocks are received and then performs subsequent transmissions, which is beneficial to reducing the transmission delay caused by waiting for HARQ feedback to a certain extent.

[0235] Those skilled in the art can understand that the foregoing multiple embodiments executed by the network device can be implemented independently or in any combination, and the embodiments of the present disclosure do not limit this.
