Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to an uplink hybrid automatic repeat request (HARQ) transmission method, apparatus, electronic device, and storage medium. Background Technology

[0002] In the HARQ mechanism, the base station sends downlink control information (DCI) to the user equipment to schedule uplink data. The user equipment sends uplink data to the base station through uplink HARQ. If the base station fails to receive the uplink data due to network conditions or other reasons, or fails to decode the uplink data, the user equipment needs to retransmit the uplink data.

[0003] In high-latency scenarios such as non-terrestrial networks (NTNs), HARQ retransmissions waste uplink HARQ resources and affect data transmission. Therefore, in NTN scenarios, uplink HARQ retransmission is disabled. This means that user equipment (UE) immediately releases the UL HARQ process after reaching a designated time slot without uploading or after completing uploading, and the base station also immediately releases the UL HARQ process after reaching a designated time slot without receiving uplink data. This allows for the effective utilization of uplink HARQ resources.

[0004] However, disabling uplink HARQ retransmission will affect the base station-side algorithm that relies on HARQ feedback. Summary of the Invention

[0005] This invention provides an uplink HARQ transmission method, apparatus, electronic device, and storage medium that can meet the requirements of high-latency HARQ transmission without affecting algorithms that rely on HARQ feedback.

[0006] In a first aspect, embodiments of the present invention provide an uplink HARQ transmission method applied to a base station, the method comprising:

[0007] The target uplink UL HARQ process is used to send uplink scheduling signaling to the user equipment so that the user equipment uploads uplink data for a specified number of time slots.

[0008] If it is determined that no uplink data is received within the specified time slot, it is determined whether the target UL HARQ process is configured with enable feedback. If so, the release of the target UL HARQ process is prohibited until uplink data uploaded by the user equipment in response to the uplink scheduling signaling is received, at which point the target UL HARQ process is released.

[0009] Secondly, embodiments of the present invention provide an uplink HARQ transmission method applied to a user equipment, the method comprising:

[0010] After receiving uplink scheduling signaling sent by the base station, uplink data for responding to the uplink scheduling signaling is obtained; the uplink scheduling signaling is used to instruct the user equipment to upload uplink data for a specified number of time slots using a specified UL HARQ process.

[0011] When it is determined that uplink data has not been uploaded within the specified time slot, it is determined whether the specified UL HARQ process is configured with enable feedback. If so, the release of the specified UL HARQ process is prohibited until the uplink data is uploaded.

[0012] Thirdly, embodiments of the present invention also provide an uplink HARQ transmission device applied to a base station, the device comprising:

[0013] The transmission unit is used to send uplink scheduling signaling to the user equipment using the target uplink UL HARQ process, so that the user equipment uploads uplink data for a specified number of time slots;

[0014] The determination and processing unit is used to determine whether the target UL HARQ process is configured with enable feedback when it is determined that no uplink data is received in the specified time slot. If so, the release of the target UL HARQ process is prohibited until uplink data uploaded by the user equipment for the uplink scheduling signaling is received, at which point the target UL HARQ process is released.

[0015] Fourthly, embodiments of the present invention also provide an uplink HARQ transmission device for use by a user, the device comprising:

[0016] The data acquisition unit is used to acquire uplink data in response to the uplink scheduling signaling after receiving the uplink scheduling signaling sent by the base station; the uplink scheduling signaling is used to instruct the user equipment to upload uplink data in a specified number of time slots using a specified UL HARQ process.

[0017] The judgment and processing unit is used to determine whether the specified UL HARQ process is configured with enable feedback when it is determined that uplink data has not been uploaded within the specified time slot. If so, the release of the specified UL HARQ process is prohibited until the uplink data is uploaded.

[0018] Fifthly, embodiments of the present invention also provide an electronic device, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, it implements the method described in any embodiment of this specification.

[0019] In a sixth aspect, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed in a computer, causes the computer to perform the methods described in any embodiment of this specification.

[0020] This invention provides an uplink HARQ transmission method, apparatus, electronic device, and storage medium. It pre-configures enable feedback for the UL HARQ process. When uplink data uploaded by the user equipment is not received within a specified number of time slots, and it is determined that the UL HARQ process is configured with enable feedback, the release of the UL HARQ process is prohibited until the uplink data is received. Therefore, this solution retains HARQ feedback while disabling uplink HARQ retransmission, thus ensuring that base station-side algorithms relying on HARQ feedback remain unaffected.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] As mentioned earlier, in the NTN scenario, after disabling uplink HARQ retransmission, the base station uses the target UL HARQ process to send uplink scheduling signaling to the user equipment to instruct the user equipment to upload the scheduled uplink data using the specified UL HARQ process within a specified number of time slots. If the base station does not receive the uplink data within the specified number of time slots, it assumes that there is a data transmission error or a problem with the air interface, and the target UL HARQ process is released directly upon reaching the specified number of time slots. On the user equipment side, if the user equipment fails to send uplink data within the specified number of time slots, it will no longer send the uplink data and will release the specified UL HARQ process directly.

[0033] However, the failure to receive uplink data within a specified time slot is not necessarily due to default reasons. Since the satellite is in motion in its orbit, it's necessary to calculate whether adjustments to certain communication parameters are needed based on the HARQ feedback from the user equipment regarding the uplink scheduling signaling. Therefore, it is essential to wait for the user equipment's HARQ feedback on the uplink scheduling signaling.

[0034] Based on this, the inventive concept of the present invention is as follows: while disabling uplink HARQ retransmission, uplink HARQ feedback is retained, so that the user equipment releases the UL HARQ process after sending uplink data, and the base station releases the UL HARQ process after receiving uplink data.

[0035] The following describes the specific implementation of the above concept.

[0036] Please refer to Figure 1 This invention provides an uplink hybrid automatic repeat request (HARQ) transmission method applied to a base station, the method comprising:

[0037] Step 100: Use the target uplink UL HARQ process to send uplink scheduling signaling to the user equipment so that the user equipment uploads uplink data for a specified number of time slots;

[0038] Step 102: When it is determined that the uplink data has not been received in the specified time slot, determine whether the target ULHARQ process is configured with enable feedback. If so, prevent the release of the target UL HARQ process until the uplink data uploaded by the user equipment for the uplink scheduling signaling is received, and then release the target UL HARQ process.

[0039] In this embodiment of the invention, enable feedback is pre-configured for the UL HARQ process. If no uplink data is received from the user equipment within a specified number of time slots, and it is determined that the UL HARQ process is configured with enable feedback, then the UL HARQ process is prevented from being released until the uplink data is received. Therefore, this solution retains HARQ feedback while disabling uplink HARQ retransmission, thus ensuring that algorithms relying on HARQ feedback on the base station side remain unaffected.

[0040] In this embodiment of the invention, when a user equipment accesses a base station, the base station allocates UL HARQ process resources to the user equipment, and allocates different numbers of UL HARQ processes to the user equipment based on its different processing capabilities. For example, 16 UL HARQ processes or 32 UL HARQ processes may be allocated to the user equipment.

[0041] Furthermore, when allocating UL HARQ processes to user equipment, the maximum number of transmissions and feedback parameters can be configured for each UL HARQ process.

[0042] The maximum number of transmissions is used to indicate whether the UL HARQ process can retransmit data after failing to upload the uplink and the number of times it can retransmit. If the maximum number of transmissions is configured to 1, it means that retransmission is not possible. If the maximum number of transmissions is configured to an integer n greater than 1, it means that the number of times it can retransmit is (n-1).

[0043] Feedback parameters are used to indicate whether the user equipment (UE) needs to wait for uplink data transmission to complete before releasing the UL HARQ process, and whether the base station needs to wait for uplink data reception to complete before releasing the UL HARQ process. If the configured feedback parameter is enabled, it indicates that the UE needs to wait for uplink data transmission to complete before releasing the UL HARQ process, and the base station needs to wait for uplink data reception to complete before releasing the UL HARQ process. If the configured feedback parameter is disabled, it indicates that the UE does not need to wait for uplink data transmission to complete; it can release the UL HARQ process as long as the specified upload time slot is reached, even if the uplink data has not been transmitted. Similarly, the base station does not need to wait for uplink data reception to complete; it can release the UL HARQ process as long as the specified upload time slot is reached, even if the uplink data has not been received.

[0044] In one embodiment of the present invention, enable feedback can be configured for all UL HARQ processes in the UL HARQ processes allocated to the user equipment, and the user equipment can be instructed to configure use feedback for all UL HARQ processes. In this way, each UL HARQ process can only be released after completing data upload and reception, thereby ensuring that the data dependent on the algorithm on the base station side that relies on UL HARQ feedback is more accurate, and thus improving the accuracy of the algorithm calculation results.

[0045] In another embodiment of the present invention, if all UL HARQ processes are configured to enable feedback, data transmission will be blocked when the network condition is poor. Therefore, enable feedback can be configured for some of the UL HARQ processes allocated to the user equipment, and the user equipment can be instructed to configure enable feedback for the same part of the UL HARQ processes.

[0046] The number of UL HARQ processes that are enabled for feedback can be determined based on the actual application scenario. For scenarios with high accuracy requirements, more UL HARQ processes can be configured to enable feedback, such as 2 / 3 of the UL HARQ processes. For scenarios with lower accuracy requirements, fewer UL HARQ processes can be configured to enable feedback, such as half or 1 / 3 of the UL HARQ processes.

[0047] During uplink scheduling, the selection of which UL HARQ process to perform uplink scheduling is controlled and determined by the base station. When some UL HARQ processes are configured to enable feedback, the base station can select either a UL HARQ process with enabled feedback as the target UL HARQ process during uplink scheduling, or a UL HARQ process without enabled feedback as the target UL HARQ process. Specifically, in one embodiment of the present invention, the selection of whether a UL HARQ process with enabled feedback is configured can be based on the communication status with the user equipment, and the selected UL HARQ process can be used as the target UL HARQ process to send uplink scheduling signaling to the user equipment.

[0048] When a base station sends uplink scheduling signaling to a user equipment (UE), it needs to instruct the UE to upload a designated UL HARQ process for uplink data. It can be understood that in this embodiment of the invention, the base station selects UL HARQ processes configured with the same feedback parameters as both the target UL HARQ process and the designated UL HARQ process. That is, when selecting a UL HARQ process with enabled feedback as the target UL HARQ process, it also selects a UL HARQ process with enabled feedback as the designated UL HARQ process; and when selecting a UL HARQ process without enabled feedback as the target UL HARQ process, it also selects a UL HARQ process without enabled feedback as the designated UL HARQ process. This ensures that when the UE provides enabled feedback for uplink data, the base station will wait for the uplink data; and when the UE does not provide enabled feedback for uplink data, the base station does not need to wait for the uplink data. To prevent a situation where the user equipment's designated UL HARQ process is not configured with enabled feedback, while the base station's target UL HARQ process is configured with enabled feedback, resulting in the user equipment releasing the designated UL HARQ process before completing uplink data upload, while the base station continues to wait for the user equipment's uploaded data, causing the target UL HARQ process to be unable to be released.

[0049] For one of the implementation methods, please refer to Figure 2 The selection of whether to configure a UL HARQ process with enable feedback based on the communication status with the user equipment may include:

[0050] Step 200: Based on the first number of uplink data that could not be received in the corresponding specified time slots during the current stage, and the second number of uplink data that could be received in the corresponding specified time slots, the ratio of the first number to the second number is taken as the communication status with the user equipment.

[0051] Step 202: Determine whether the ratio is greater than a set threshold; if the ratio is greater than the set threshold, proceed to step 204; otherwise, proceed to step 206.

[0052] Step 204: Prioritize UL HARQ processes configured with enable feedback;

[0053] Step 206: Prioritize UL HARQ processes that are not configured with enable feedback.

[0054] In this embodiment of the invention, a first number of uplink data that failed to be received within a specified time slot and a second number of uplink data that could be received within the specified time slot are counted within a certain period. The communication status between the base station and the user equipment can be determined by calculating the ratio of the first number to the second number. If the ratio is smaller, it indicates a better communication status. When the communication status is better, there are fewer cases where uplink data was not received within the specified time slot. In this way, UL HARQ processes without enabled feedback can be preferentially selected. Conversely, if the ratio is larger, it indicates a poor communication status. It is necessary to calculate the corresponding algorithm on the base station side based on the uplink HARQ feedback from the user equipment to measure which situation caused the poor communication status. In this way, UL HARQ processes with enabled feedback should be preferentially selected to improve the accuracy of the HARQ feedback data on which they are based.

[0055] In step 200, the current stage can be a preset duration, such as 10 minutes.

[0056] In step 200, when calculating the first and second quantities, it is important to ensure that their statistical ranges are as similar as possible. For example, if there are 100 uplink data scheduling records in the current stage, of which 60 uplink data records are scheduled using a UL HARQ process configured with feedback enabled, and 40 uplink data records are scheduled using a UL HARQ process not configured with feedback enabled, then the first and second quantities can be calculated for the 60 uplink data records scheduled using a UL HARQ process configured with feedback enabled, for example, the first quantity is 5 and the second quantity is 55; alternatively, the first and second quantities can be calculated for the 40 uplink data records scheduled using a UL HARQ process not configured with feedback enabled, for example, the first quantity is 3 and the second quantity is 37; and of course, the first and second quantities can be calculated for all 100 uplink data records, for example, the first quantity is 8 and the second quantity is 92.

[0057] In traditional NTN systems, UL HARQ retransmission is disabled. If a base station does not receive uplink data within a specified number of time slots, it directly releases the target UL HARQ process. However, in this embodiment of the invention, a judgment step is added before releasing the target UL HARQ process. Specifically, it checks whether the release of the target UL HARQ process is configured with enable feedback. If no enable feedback is configured, the target UL HARQ process can be released directly. If enable feedback is configured, it is necessary to wait for uplink data uploaded by the user equipment and prohibit the release of the target UL HARQ process until uplink data uploaded by the user equipment in response to the uplink scheduling signaling is received, at which point the target UL HARQ process is released.

[0058] As can be seen, in this embodiment of the invention, the HARQ RTT does not increase due to the increase in latency. It only sacrifices a portion of the efficiency of the UL HARQ process to ensure that the algorithm on the base station side that relies on UL HARQ feedback obtains the dependent data.

[0059] Please refer to Figure 3 This invention provides an uplink HARQ transmission method, applied to a user equipment, comprising:

[0060] Step 300: After receiving the uplink scheduling signaling sent by the base station, acquire the uplink data used to respond to the uplink scheduling signaling; the uplink scheduling signaling is used to instruct the user equipment to upload uplink data in a specified number of time slots using a specified UL HARQ process.

[0061] Step 302: When it is determined that uplink data has not been uploaded in the specified time slot, determine whether the specified UL HARQ process is configured with enable feedback. If so, prevent the release of the specified UL HARQ process until the uplink data is uploaded.

[0062] In this embodiment of the invention, enable feedback is pre-configured for the UL HARQ process. When uplink data cannot be uploaded to the base station within a specified number of time slots, and it is determined that the UL HARQ process is configured with enable feedback, the release of the UL HARQ process is prohibited until the uplink data transmission is completed. Therefore, this scheme retains HARQ feedback while disabling uplink HARQ retransmission, thus ensuring that algorithms relying on HARQ feedback on the base station side remain unaffected.

[0063] In one embodiment of the present invention, the method further includes: configuring enable feedback for a portion of the UL HARQ processes allocated for the user equipment based on an indication from the base station.

[0064] The base station and user equipment maintain the same feedback parameters for the UL HARQ process. In other words, the user equipment must also configure enable feedback for the same UL HARQ processes that the base station has configured.

[0065] Since the uplink scheduling signaling indicates the number of time slots for uplink data upload, uplink data upload needs to be performed within that specified time slot. In the traditional NTN mechanism for disabling uplink HARQ retransmission, if the uplink data cannot be uploaded within the specified time slot, even if the uplink data is ready, it will not be sent again, and the specified ULHARQ process used for uplink data transmission will be immediately released. However, in this embodiment of the invention, when it is determined that uplink data cannot be uploaded within the specified time slot, a judgment step needs to be added before releasing the specified ULHARQ process. That is, it is determined whether the specified ULHARQ process is configured with enable feedback. If it is not configured with enable feedback, then data upload will not be sent and the specified ULHARQ process will be released immediately; if it is configured with enable feedback, then the release of the specified ULHARQ process will be prohibited until the uplink data upload is completed, at which point the specified ULHARQ process will be released.

[0066] As can be seen, in this embodiment of the invention, the HARQ RTT does not increase due to the increase in latency. It only sacrifices a portion of the efficiency of the UL HARQ process to ensure that the algorithm on the base station side that relies on UL HARQ feedback obtains the dependent data.

[0067] Please refer to Figure 4 This invention provides an uplink HARQ transmission device applied to a base station, the device comprising:

[0068] Transmission unit 401 is used to send uplink scheduling signaling to user equipment using the target uplink UL HARQ process, so that the user equipment uploads uplink data for a specified number of time slots;

[0069] The judgment processing unit 402 is used to determine whether the target UL HARQ process is configured with enable feedback when it is determined that the uplink data has not been received in the specified time slot. If so, the release of the target UL HARQ process is prohibited until the uplink data uploaded by the user equipment for the uplink scheduling signaling is received, and then the target UL HARQ process is released.

[0070] In one embodiment of the present invention, please refer to Figure 5 The device may also include:

[0071] Configuration unit 403 is configured to configure enable feedback for a portion of the UL HARQ processes allocated to the user equipment, and to instruct the user equipment to configure enable feedback for the same portion of the UL HARQ processes.

[0073] Selection unit 404 is used to select whether a UL HARQ process with enable feedback is configured based on the communication status with the user equipment, and to use the selected UL HARQ process as the target UL HARQ process.

[0074] In one embodiment of the present invention, the selection unit is specifically used to: based on a first number of uplink data that could not be received in the corresponding specified time slots during the current stage, and a second number of uplink data that could be received in the corresponding specified time slots, take the ratio of the first number to the second number as the communication status with the user equipment; if the ratio is greater than a set threshold, then a UL HARQ process configured with enabled feedback is selected first; otherwise, a UL HARQ process without enabled feedback is selected first.

[0077] The judgment processing unit 702 is used to determine whether the specified UL HARQ process is configured with enable feedback when it is determined that uplink data has not been uploaded in the specified time slot. If so, the release of the specified UL HARQ process is prohibited until the uplink data is uploaded.

[0079] Configuration unit 703 is configured to configure enable feedback for a portion of the UL HARQ processes allocated for the user equipment based on an instruction from the base station.
