Technical Field

[0001] This application relates to the field of communications, specifically to a control method, a communication device, and a storage medium. Background Technology

[0002] Hybrid Automatic Repeat Request (HARQ) is a technique that combines Forward Error Correction (FEC) and Automatic Repeat Request (ARQ), and uses ACK (Acknowledgment) / NACK (Negative Acknowledgment) messages for feedback.

[0003] In conceiving and implementing this application, the inventors discovered that in some implementations, in order to alleviate HARQ stalling caused by large network propagation delays, and to improve the power consumption and latency issues of terminal devices, HARQ feedback can be disabled. However, there is no suitable solution for how to disable HARQ feedback, which is an urgent problem to be solved.

[0057] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0058] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word “if” as used herein may be interpreted as “when…” or “in response to determination”. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms “or,” “and / or,” “including at least one of the following,” etc., as used in this application may be interpreted as inclusive, or mean any one or any combination thereof. For example, "including at least one of the following: A, B, C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Similarly, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Exceptions to this definition only occur when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0059] It should be understood that although the steps in the flowcharts of this application's embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0060] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

In specific implementation, those skilled in the art may execute S502 first and then S501, etc., but these should all be within the protection scope of this application.

[0062] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0063] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0078] The processor 110 is the control center of the terminal device, connecting various parts of the terminal device through various interfaces and lines.

[0079] The terminal device 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0080] although Figure 1 As not shown, the terminal device 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0081] To facilitate understanding of the embodiments of this application, the communication network system upon which the terminal device of this application is based is described below.

The embodiments of this application do not limit the specific technology or specific device form used in the network device.

[0082] Please see Figure 2 , Figure 2 This application provides a communication network system architecture diagram. The communication network system is an LTE system based on the universal mobile communication technology. The LTE system includes a User Equipment (UE) 201, an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) 202, an Evolved Packet Core (EPC) 203, and the operator's IP (Internet Protocol) service 204, which are connected in sequence.

It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).

[0086] IP services 204 may include the Internet, intranet, IP Multimedia Subsystem (IMS) or other IP services.

[0087] Although the above description uses the LTE system as an example, those skilled in the art should understand that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems (such as 5G, NR-NTN, IoT-NTN, NB-IoT), etc., which are not limited here.

[0088] Based on the aforementioned terminal device hardware structure and communication network system, various embodiments of this application are proposed.

[0089] To facilitate understanding of the solutions provided in the embodiments of this application, HARQ feedback is described below:

[0090] HARQ is a technique that combines FEC and ARQ, using ACK / NACK messages for feedback. HARQ technology offers anti-interference and anti-fading capabilities, and can improve system throughput (efficiency) and data transmission reliability. However, it also suffers from significant propagation delays, leading to HARQ congestion and increased power consumption and transmission latency in terminal devices. Disabling HARQ feedback can improve power consumption and transmission latency in terminal devices, but it also reduces data transmission reliability. Therefore, how to reasonably enable HARQ feedback remains a problem to be solved.

[0091] Based on the above description, in order to reasonably enable HARQ feedback, improve transmission efficiency, and ensure transmission reliability, this application provides a control method, a communication device, and a storage medium. The control method, communication device, and storage medium provided in the embodiments of this application will be further described in detail below.

[0092] Figure 3 This is a flowchart illustrating a control method provided in an embodiment of this application. Figure 3 As shown, the control method includes the following step S301. Figure 3 The method shown can be executed by a terminal device. Alternatively, Figure 3 The method shown can be executed by a chip in a terminal device. Figure 3 The method will be explained using a terminal device as the executing entity.

[0093] S301, The terminal device determines whether to enable HARQ feedback based on the first parameter.

[0094] In this embodiment, the first parameter may be sent by a network device or other associated device, or it may be specified by a protocol; no limitation is made here. If the first parameter is sent by a network device or other associated device, it is beneficial to improve the flexibility of the first parameter; if the first parameter is specified by a protocol, it is beneficial to improve the efficiency of the terminal device in determining whether to enable HARQ feedback. Based on the first parameter, the terminal device can reasonably enable HARQ feedback to improve transmission efficiency while ensuring transmission reliability.

[0095] In one possible implementation, the first parameter includes at least one of the following: a repetition count threshold and an offset threshold. In one embodiment, the first parameter can also be other parameters, such as indicating the HARQ feedback status of each HARQ process, etc., and is not limited thereto. For example, the first parameter may include a repetition count threshold, such as 16 times. Another example is that the first parameter may include an offset threshold, such as 400ms.

[0096] (1) The first parameter is the threshold value for the number of repetitions.

[0097] In one implementation, the repetition threshold is a threshold value for the number of repetitions of the Narrow-band Physical Downlink Shared Channel (NPDSCH) corresponding to the HARQ feedback.

[0098] It should be noted that when scheduling NPDSCH, network devices can ensure coverage for terminal devices by increasing NPDSCH repetitions. An NPDSCH repetition can be considered a downlink retransmission. The terminal device demodulates by merging NPDSCH repetitions to ensure the reliability of downlink transmission. Under the same channel conditions, the higher the repetition count, the better the reliability. Therefore, when the NPDSCH repetition count reaches a preset threshold, the reliability of data transmission can be considered guaranteed. At this point, HARQ feedback can be disabled to improve transmission efficiency. In other words, the terminal device can determine whether to disable HARQ feedback based on the repetition count threshold.

[0099] In one implementation, the repetition number threshold is the repetition number threshold value corresponding to the coverage level of the terminal device. It should be noted that the reliability of channel transmission varies depending on the coverage level of the terminal device, therefore the required repetition number threshold value will also be different.

[0100] For example, as shown in Table 1, when the coverage level of the terminal device is 0, the threshold for the number of repetitions is 4 times; when the coverage level of the terminal device is 1, the threshold for the number of repetitions is 8 times; and when the coverage level of the terminal device is 2, the threshold for the number of repetitions is 16 times.

[0101] Table 1

[0102] Coverage level of the terminal device Repetition threshold 0 4 times 1 8 times 2 16 times

[0103] (2) The first parameter is the offset threshold value.

[0104] In one implementation, the offset threshold value is the threshold value of the offset of the original scheduling sequence.

[0105] It should be noted that HARQ stalling in non-terrestrial networks is mainly caused by large propagation delays, specifically reflected in the offset of the original scheduling sequence, i.e., Koffset. Network devices will issue cell-specific offsets (CellSpecificKoffset) through System Information Block (SIB), which can be considered as the initial scheduling offset and are effective for all terminal devices. After the terminal device reports the TA report, the network device will issue differential offsets (DifferentialKoffset) through MAC CE signaling to adjust the initial scheduling offset, thereby obtaining the offset of the original scheduling sequence of the terminal device, i.e., formula (1):

[0106] Koffset = CellSpecificKoffset- DifferentialKoffset (1)

[0107] When Koffset is large, it significantly impacts the scheduling of terminal devices, increasing transmission latency. Therefore, to ensure efficient scheduling of terminal devices, HARQ feedback can be disabled when the offset of the original scheduling sequence reaches a preset threshold. In other words, the terminal device can determine whether to disable HARQ feedback based on the threshold value of the offset of the original scheduling sequence.

[0108] In one possible implementation, the method further includes: the terminal device receiving first information indicating the first parameter. It should be noted that the first parameter can be carried within the first information, and the network device or other associated devices can send the first information to the terminal device so that the terminal device can obtain the first parameter. This approach improves the flexibility of the first parameter.

[0109] In one implementation, the first information is carried in Radio Resource Control (RRC) signaling or Media Access Control Control Element (MACCE) signaling.

[0110] In one possible implementation, the first parameter includes a repetition number threshold. When the terminal device determines whether to enable HARQ feedback based on the first parameter, the specific implementation may be: if the repetition number of the NPDSCH corresponding to the HARQ feedback is greater than or equal to the repetition number threshold, then the terminal device disables the HARQ feedback.

[0111] For example, such as Figure 4aAs shown, k0 represents the offset between the NPUSCH start subframe carrying HARQ feedback and the corresponding NPDSCH end subframe in the Terrestrial Network (TN). Assuming the NPDSCH corresponding to this HARQ feedback is repeated 8 times, after the NPDSCH transmission ends, after an offset of k0, the terminal device performs HARQ-ACK / NACK feedback based on the NPDSCH demodulation result.

[0112] like Figure 4b As shown, compared to terrestrial networks, HARQ stalling in non-terrestrial networks is mainly due to larger propagation delays, specifically reflected in the offset (Koffset) of the original scheduling sequence. Assume the NPDSCH corresponding to this HARQ feedback repeats 8 times, and the terminal device obtains a repetition threshold value of 16 times indicated by the first parameter. Since the NPDSCH repetition count corresponding to this HARQ feedback is less than this repetition threshold value, the terminal device enables this HARQ feedback. That is, after the NPDSCH transmission ends, after an offset of k0 + Koffset, the terminal device performs HARQ-ACK / NACK feedback based on the NPDSCH demodulation result.

[0113] like Figure 4c As shown, in a non-terrestrial network, assuming the NPDSCH corresponding to the HARQ feedback is repeated 16 times, the terminal device obtains the repetition threshold value indicated by the first parameter as 16 times. Since the repetition number of the NPDSCH corresponding to the HARQ feedback is equal to the repetition threshold value, the terminal device disables the HARQ feedback, that is, after the NPDSCH transmission is completed, the terminal device does not perform HARQ-ACK / NACK feedback.

[0114] In one possible implementation, the first parameter includes an offset threshold. When the terminal device determines whether to enable HARQ feedback based on the first parameter, the specific implementation may be: if the offset of the original scheduling sequence corresponding to the HARQ feedback is greater than or equal to the offset threshold, then the terminal device enables the HARQ feedback.

[0115] For example, such as Figure 4dAs shown, in a non-terrestrial network, assuming the NPDSCH corresponding to the HARQ feedback is repeated 8 times, the offset of the original scheduling sequence corresponding to the HARQ feedback is 300ms, and the terminal device obtains the offset threshold value indicated by the first parameter as 400ms. Since the offset of the original scheduling sequence corresponding to the HARQ feedback is less than the offset threshold value, the terminal device enables the HARQ feedback. That is, after the NPDSCH transmission is completed, the terminal device performs HARQ-ACK / NACK feedback based on the NPDSCH demodulation result.

[0116] like Figure 4e As shown, in a non-terrestrial network, assuming the NPDSCH corresponding to the HARQ feedback is repeated 8 times, the offset of the original scheduling sequence corresponding to the HARQ feedback is 1023ms, and the terminal device obtains an offset threshold value of 400ms indicated by the first parameter. Since the offset of the original scheduling sequence corresponding to the HARQ feedback is greater than the offset threshold value, the terminal device disables the HARQ feedback. That is, after the NPDSCH transmission is completed, the terminal device does not perform HARQ-ACK / NACK feedback.

[0117] In one possible implementation, the first parameter includes the repetition number threshold value, and the method further includes: the terminal device receiving downlink control information (DCI) for scheduling the NPDSCH corresponding to the HARQ feedback, the DCI including a repetition number compensation value; and adjusting the repetition number of the NPDSCH based on the repetition number compensation value (delta). In one embodiment, the repetition number compensation value can be positive or negative. This method can improve transmission reliability or transmission efficiency. Specifically, the repetition number of the NPDSCH can be adjusted using formula (2):

[0118] Number of repetitions of NPDSCH = NPDSCHrepetition + delta (2)

[0119] It should be noted that this repetition compensation value can be positive, which can improve transmission reliability. Assuming the repetition threshold indicated by the first parameter is 8 times, and the network device configures 4 repetitions for the first NPDSCH scheduling, the terminal device needs to perform HARQ feedback. Based on the feedback result, the current channel reliability is relatively low. In the next NPDSCH scheduling, to ensure downlink demodulation, the network device may configure 8 repetitions. At this time, the NPDSCH repetition count corresponding to the HARQ feedback reaches the repetition threshold, so the terminal device disables HARQ feedback. However, the NPDSCH repetition count corresponding to this HARQ feedback is increased to 8 times through downlink adaptive modulation and coding (AMC) adjustment. Therefore, the current channel reliability may still be relatively low, so an additional 8 NPDSCH repetitions can be added to ensure transmission reliability. In other words, with a repetition compensation value of 8 times (delta = 8), the adjusted NPDSCH repetition count is 16 times.

[0120] Additionally, the repetition compensation value can also be negative, which can improve transmission efficiency. Assuming the repetition threshold indicated by the first parameter is 8 times, when the network device schedules NPDSCH for the first time, it configures the NPDSCH repetition count corresponding to the HARQ feedback to be 1 time. Therefore, the terminal device needs to perform HARQ feedback, and the feedback result indicates that the current channel reliability is relatively high. When the network device schedules NPDSCH for the next time, in order to disable HARQ feedback, it configures the NPDSCH repetition count to be 8 times. At this time, because the NPDSCH repetition count has reached the repetition threshold, the terminal device disables HARQ feedback. However, in reality, the NPDSCH corresponding to the HARQ feedback only needs to be repeated once. Therefore, to save NPDSCH resources, it is necessary to adjust the NPDSCH repetition count corresponding to the HARQ feedback, which can reduce the NPDSCH repetition by 7 times. In other words, the repetition compensation value is -7 times (delta is -7). The adjusted NPDSCH repetition count is still 1 time, but by disabling the corresponding HARQ feedback, transmission efficiency is improved.

[0121] In one possible implementation, the method further includes: the terminal device receiving a DCI for scheduling the NPDSCH corresponding to the HARQ feedback, the DCI including a first parameter, the first parameter being used to indicate whether the terminal device disables the HARQ feedback.

[0122] It should be noted that network devices can use DCI to indicate the scheduling resources for NPDSCH and the corresponding HARQ-ACK resources during dynamic scheduling. The first parameter in this DCI is used to dynamically indicate whether the current scheduling requires HARQ feedback. If the first parameter indicates that the current scheduling requires HARQ feedback, the terminal device receives NPDSCH on the resources indicated by the DCI and performs HARQ feedback on the corresponding resources. If the first parameter indicates that the current scheduling disables HARQ feedback, the HARQ-ACK resources indicated by the DCI are invalid, and the terminal device only needs to receive NPDSCH on the resources indicated by the DCI without performing HARQ feedback.

[0123] In one implementation, the first parameter can be reused in the DCI by reusing other fields or adding a HARQ feedback field to dynamically indicate whether the current schedule requires HARQ feedback.

[0124] For example, suppose a HARQ feedback field exists in the DCI. If the HARQ feedback field is False, it instructs the terminal device to disable HARQ feedback. If the HARQ feedback field is True, it instructs the terminal device to enable HARQ feedback.

[0125] It can be seen that, based on Figure 3 The described method enables terminal devices to reasonably enable HARQ feedback, improving transmission efficiency while ensuring transmission reliability.

[0126] Figure 5 This is a flowchart illustrating another control method provided in an embodiment of this application. For example... Figure 5 As shown, the control method includes the following step S501. Figure 5 The method shown can be executed by a terminal device. Alternatively, Figure 5 The method shown can be executed by a chip in a terminal device. Figure 5 The method will be explained using a terminal device as the executing entity.

[0127] S501, The terminal device responds to the first preset condition by disabling HARQ feedback.

[0128] In this embodiment, when a first preset condition is met, the terminal device can enable HARQ feedback. That is, the first preset condition is used to determine whether to enable HARQ feedback. This method allows for the reasonable enabling of HARQ feedback, thereby improving transmission efficiency while ensuring transmission reliability.

[0129] In one possible implementation, satisfying the first preset condition includes at least one of the following: the number of repetitions of the NPDSCH corresponding to the HARQ feedback is greater than or equal to a repetition count threshold; the offset of the original scheduling sequence corresponding to the HARQ feedback is greater than or equal to an offset threshold. That is, when the number of repetitions of the NPDSCH corresponding to the HARQ feedback is greater than or equal to the repetition count threshold, the terminal device disables HARQ feedback. Alternatively, when the offset of the original scheduling sequence corresponding to the HARQ feedback is greater than or equal to the offset threshold, the terminal device disables HARQ feedback.

[0130] In one possible implementation, at least one of the following is included: the repetition number threshold is a threshold value for the repetition number of the NPDSCH corresponding to the HARQ feedback; the repetition number threshold is a threshold value for the repetition number corresponding to the coverage level of the terminal device; and the offset threshold is a threshold value for the offset of the original scheduling sequence.

[0131] In one possible implementation, the number of repetitions of the NPDSCH corresponding to the HARQ feedback is greater than or equal to a repetition count threshold. The method further includes: the terminal device receiving a DCI for scheduling the NPDSCH corresponding to the HARQ feedback, the DCI including a repetition count compensation value; and adjusting the number of repetitions of the NPDSCH based on the repetition count compensation value.

[0132] In one possible implementation, the repetition count threshold or the offset threshold is obtained through the received first information. It should be noted that the repetition count threshold or the offset threshold is carried in the first information, which may be sent to the terminal device by the network device or other associated devices; this is not limited here.

[0133] In one possible implementation, the network device determines the HARQ feedback status of each HARQ process and sends it to the terminal device via a first parameter, provided that a first preset condition is met. Specifically, the HARQ process used for transmission is determined based on the QoS requirements of the currently transmitted service. If the reliability requirement of the service is high, the service can be transmitted through a HARQ process with enabled HARQ feedback; if the rate requirement of the service is high, the service can be transmitted through a HARQ process with disabled HARQ feedback.

[0134] In one implementation, the first information is carried in RRC signaling or MAC CE signaling.

[0135] In one embodiment, the specific implementation of step S501 and one or more possible implementations can refer to the specific implementation and one or more possible implementations described in step S301 above, and will not be repeated here.

[0136] It can be seen that, based on Figure 5 The described method enables terminal devices to reasonably enable HARQ feedback, improving transmission efficiency while ensuring transmission reliability.

Figure 6 As shown, the control method includes the following steps S601 and S602. Figure 6 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 6 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 6 The method will be explained using terminal devices and network devices as examples.

[0138] S601, the network device sends first information indicating a first parameter, which is used to determine whether to enable HARQ feedback. Accordingly, the terminal device can receive the first information.

[0139] In this embodiment of the application, the network device sends the first parameter to the terminal device through the first information, which helps to improve the flexibility of the first parameter.

[0140] In one possible implementation, the first parameter includes at least one of the following: a repetition number threshold and an offset threshold. In one embodiment, the first parameter may also be other parameters, such as indicating the HARQ feedback status of each HARQ process, etc., which are not limited here.

[0141] In one possible implementation, at least one of the following is included: the repetition number threshold is a threshold value for the repetition number of the NPDSCH corresponding to the HARQ feedback; the repetition number threshold is a threshold value for the repetition number corresponding to the coverage level of the terminal device; and the offset threshold is a threshold value for the offset of the original scheduling sequence.

[0142] In one possible implementation, the first parameter includes a repetition count threshold, and the method further includes: the network device sending a DCI for scheduling the NPDSCH corresponding to the HARQ feedback. Accordingly, the terminal device receives the DCI, which includes a repetition count compensation value; the terminal device adjusts the repetition count of the NPDSCH based on the repetition count compensation value.

[0143] In one possible implementation, the network device determines the HARQ feedback status of each HARQ process and sends it to the terminal device via a first parameter, provided that a first preset condition is met. Specifically, the HARQ process used for transmission is determined based on the QoS requirements of the currently transmitted service. If the reliability requirement of the service is high, the service can be transmitted through the HARQ process with enabled HARQ feedback; if the rate requirement of the service is high, the service can be transmitted through the HARQ process with disabled HARQ feedback.

[0144] In one implementation, the first information is carried in RRC signaling or MAC CE signaling.

[0145] S602, The terminal device determines whether to enable HARQ feedback based on the first parameter.

[0146] In one possible implementation, the first parameter includes the repetition number threshold. When the terminal device determines whether to enable HARQ feedback based on the first parameter, the specific implementation may be: if the repetition number of the NPDSCH corresponding to the HARQ feedback is greater than or equal to the repetition number threshold, then the HARQ feedback is disabled.

[0147] In one possible implementation, the first parameter includes the offset threshold value. When the terminal device determines whether to enable HARQ feedback based on the first parameter, the specific implementation method may be: if the offset of the original scheduling sequence corresponding to the HARQ feedback is greater than or equal to the offset threshold value, then the HARQ feedback is disabled.

[0148] In one embodiment, the specific implementation of steps S601 and S602, as well as one or more possible implementations, can be referred to the specific implementation and one or more possible implementations described in step S301 above, and will not be repeated here.

[0149] It can be seen that, based on Figure 6 The described method enables terminal devices to reasonably enable HARQ feedback, improving transmission efficiency while ensuring transmission reliability.
