Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a resource scheduling method, apparatus, device, storage medium, and computer program product. Background Technology

[0002] There are two existing uplink data transmission scheduling methods: Dynamic Grant (DG) and Semi-Static Grant (CG). Dynamic Grant involves the terminal device sending a Scheduled Request (SR) / Buffer Status Report (BSR) to the base station via Media Access Control (MAC) signaling, specifying the amount of uplink data to be transmitted. The base station then issues dynamic scheduling instructions for uplink transmission via the Physical Downlink Control Channel (PDCCH). CG eliminates the need for terminal device requests, allowing uplink data transmission directly within a configured period. This effectively reduces transmission latency and ensures uplink data transmission latency requirements are met. Therefore, base stations typically configure periodic resources for terminal uplink data transmission using Radio Resource Control (RRC) in a semi-static manner.

[0003] However, since semi-static resources are pre-configured, resource waste can occur when users' uplink data transmission needs change. How to reduce the waste of pre-configured semi-static resources has become an urgent technical problem to be solved.

[0066] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0067] The embodiments of this application provide a resource scheduling method, referring to... Figure 1 As shown, the method is applied to a network device and includes the following steps:

[0068] Step 101: Obtain the first uplink feature information.

[0069] In this embodiment, the network device acquires the first uplink characteristic information corresponding to the terminal it currently manages. The first uplink characteristic information may have been collected within a certain period prior to the current time. This period may be an empirically determined duration based on actual circumstances. The network device may be a device in a communication network that establishes a communication connection with the user terminal device and provides communication network services to the user terminal device, such as a base station or network node.

[0070] Step 102: Based on the first uplink feature information, determine an allocation strategy that includes at least the uplink resource allocation information of the first group.

[0071] In this embodiment, the network device comprehensively analyzes the acquired first uplink characteristic information to determine the distribution pattern of uplink data changes in the terminal devices. This allows the network device to determine an allocation strategy for uplink resources allocated to the group of terminals managed by the network device. The first group uplink resource allocation information refers to the uplink resource information allocated by the network device to the target group of terminals it manages.

[0072] Step 103: Based on the allocation strategy, configure the first group uplink resource allocation information for the target group terminals corresponding to the network devices.

[0073] In this embodiment, after the network device determines the allocation policy, other managed group terminals perform resource analysis. For example, the network device determines the first group uplink resource allocation information to be allocated to the target group terminal and configures the first group uplink resource allocation information to the target group terminal. When configuring the first group uplink resource allocation information for the target group terminal, the network device can use a resource configuration method between the network device and the target group terminal.

[0074] Based on the foregoing embodiments, in other embodiments of this application, step 102, which determines an allocation strategy based on the first uplink feature information, including at least the first group uplink resource allocation information, can be implemented through the following steps:

[0075] The first uplink feature information is predicted using the pre-trained first resource allocation model to obtain the allocation strategy.

[0076] In this embodiment, the network device obtains a pre-trained first resource allocation model, inputs the first uplink feature information into the first resource allocation model, and performs prediction processing on the first uplink feature information through the first resource allocation model to obtain an allocation strategy.

[0077] The first resource configuration model can be obtained by training a preset resource configuration model using a large amount of uplink resource data and corresponding channel characteristic data. This first resource configuration model can also be trained on other devices and then sent to the network device. In some application scenarios, other devices can periodically update the first resource configuration model and synchronize the updated model at the network device. In other application scenarios, after the first resource configuration model is sent to the network device from other devices, the network device can update the model based on its own collected uplink resource data and corresponding channel characteristic data. This ensures that the updated first resource configuration model is more compatible with the application scenario of the network device, improving the fit between the first resource configuration model and the network device's application scenario, guaranteeing effective resource management by the network device, and ensuring the resource utilization efficiency of the network device.

[0078] Based on the foregoing embodiments, in other embodiments of this application, the allocation strategy further includes grouping information of the target group terminals.

[0079] In some application scenarios, the allocation strategy may also include target group terminals. That is, when the network device determines an allocation strategy that includes at least the first group uplink resource allocation information based on the first uplink feature information, it may also perform group allocation on the terminal devices managed by the network device and determine the allocation configuration of the corresponding uplink resources for each group of terminals. In this case, the allocation strategy indicates the allocated group terminals and the uplink resource allocation configuration information corresponding to the group terminals.

[0080] Based on the foregoing embodiments, the first uplink feature information includes at least the first historical uplink data and the first historical user channel feature data corresponding to the first historical uplink data.

[0081] In this embodiment of the application, the first historical uplink data is the data uploaded by the terminal device to the network device, and the first historical user channel characteristic data is the channel characteristic data corresponding to the data transmitted in the first historical uplink data.

[0082] Based on the foregoing embodiments, in other embodiments of this application, the first uplink feature information is communication status information collected for one or more group terminals within a first preset time period before the prediction operation is performed.

[0083] In this embodiment, the first preset duration is an empirical duration determined based on actual conditions or extensive experiments, and can be expressed in units such as seconds, minutes, hours, days, weeks, months, and days. One or more group terminals belong to the group terminals managed by the network device. The network device obtains communication status information collected from one or more group terminals within the first preset duration before performing the prediction operation, and obtains first uplink characteristic information, namely, first historical uplink data and first historical user channel characteristic data.

[0084] Based on the foregoing embodiments, in other embodiments of this application, the uplink resource allocation information of the first group includes one or more of the following:

[0085] One or more statically allocated frequency resource cycles;

[0086] Frequency resource parameters allocated for each frequency resource cycle;

[0087] Modulation coding scheme (MCS).

[0088] Based on the foregoing embodiments, in other embodiments of this application, the configuration method for configuring the uplink resource allocation information of the first group is at least the following: Radio Resource Control Protocol (RRC) signaling method.

[0089] In the embodiments of this application, the configuration method for configuring the uplink resource allocation information of the first group can also be other than the Radio Resource Control (RRC) signaling method. In some application cases, other signaling methods can also be used.

[0090] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0091] If the first information reported by the terminal devices included in the target group terminal is received, the second uplink feature information is obtained; wherein, the first information is used to indicate that the uplink data reported by the terminal device failed to upload;

[0092] The first resource allocation model is updated using the first information and the second uplink feature information to obtain the second resource allocation model.

[0093] After updating the first resource configuration model to the second resource configuration model, the steps are executed to obtain the first uplink feature information.

[0094] In this embodiment, after the target group terminals receive the first group uplink resource allocation information, when the terminal devices in the target group terminals upload data according to the first group uplink allocation information, if the terminal device detects that the uplink data upload has failed, the terminal device reports the first information to the network device. The network device determines that the resources configured based on the first group uplink resource allocation information cannot support the communication operation currently reported by the terminal device. Therefore, the network device obtains the second uplink feature information, which includes at least the second historical uplink data and the second historical user channel feature data. The second uplink feature information is the communication status information collected within a certain period before the first information was received. Then, based on the received first information and the obtained second uplink feature information, the network device updates the first resource configuration model, that is, it trains the first resource configuration model to obtain the updated second resource configuration model. Then, it updates the first resource configuration model to the second resource configuration model and repeats the process of steps 101 to 103 to determine a new allocation strategy and reallocate the first group uplink resource allocation information to the target group terminals to ensure that the group terminals corresponding to the network device have sufficient resources to upload data to the network device.

[0095] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0096] If the first information is received from the terminal devices included in the target group, the second group uplink resource allocation information is reconfigured for the terminal devices; wherein, the first information is used to indicate that the uplink data reported by the terminal devices failed to upload.

[0097] In this embodiment, after receiving the first information reported by the terminal device, in order to ensure that the terminal device can upload uplink data normally, the network device, according to the pre-configured resources, prioritizes reconfiguring the resources that can ensure the terminal device can upload data normally, obtains the second group of uplink resource allocation information, and configures the second group of uplink resource allocation information for the terminal device. In this way, the terminal device reports uplink data according to the communication resources indicated in the second group of uplink resource allocation information, ensuring the communication service of the terminal device, improving communication efficiency, and ensuring the user experience.

[0098] Based on the foregoing embodiments, in other embodiments of this application, the first information includes a resource scheduling request / buffer status report.

[0099] In this embodiment of the application, when the terminal device reports the first information, the first information can be implemented through a resource scheduling request / buffer status report.

[0100] Based on the foregoing embodiments, in other embodiments of this application, the configuration method for configuring the uplink resource allocation information of the second group is at least the following: downlink control information (DCI) method.

[0101] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0102] Receive uplink data sent by the terminal device.

[0103] In this embodiment of the application, after the network device configures the first group uplink resource allocation information and the second group uplink resource allocation information of the terminal device, the terminal device reports uplink data according to the configuration. If the reporting is successful, the network device can receive the uplink data reported by the terminal device. In this way, the network device can process the uplink data accordingly and perform subsequent related operations, such as forwarding it to the Internet.

[0104] The resource scheduling method provided in this application obtains first uplink characteristic information through a network device, determines an allocation strategy based on the first uplink characteristic information, including at least first group uplink resource allocation information, and configures the first group uplink resource allocation information for the target group terminals corresponding to the network device based on the allocation strategy, so that the terminal devices belonging to the target group terminals receive the first group uplink resource allocation information configured by the network device. In this way, the network device determines the allocation strategy corresponding to the target group terminals based on the first uplink characteristic information and configures the first group uplink resource allocation information for the target group terminals according to the allocation strategy. This dynamically adjusts the uplink resources of the target group terminals according to the actual application scenario, solving the problem of resource waste caused by changes in uplink data during current uplink data transmission. This resource scheduling method proposes a semi-static resource allocation method based on actual conditions, reducing the possibility of resource waste and improving resource utilization.

[0105] Based on the foregoing embodiments, embodiments of this application provide a resource scheduling method, which is applied to terminal devices belonging to a target group of terminals, with reference to... Figure 2 As shown, the method includes the following steps:

[0106] Step 201: Receive the first group uplink resource allocation information configured by the network device.

[0107] Among them, the uplink resource allocation information of the first group is configured by the network device based on the allocation strategy determined by the first uplink feature information.

[0108] In this embodiment of the application, after the terminal device in the target group receives the first group uplink resource allocation information configured by the corresponding network device, the terminal device configures the first group uplink resource allocation information and determines the uplink resources allocated to it by the network device. In this way, when the terminal device needs to upload uplink data to the network device, it uploads uplink data based on the uplink resources allocated by the network device.

[0109] Based on the foregoing embodiments, in other embodiments of this application, the uplink resource allocation information of the first group includes one or more of the following:

[0110] One or more statically allocated frequency resource cycles;

[0111] Frequency resource parameters allocated for each frequency resource cycle;

[0112] Modulation coding scheme (MCS).

[0113] Based on the foregoing embodiments, in other embodiments of this application, the configuration method for configuring the uplink resource allocation information of the first group is at least the following: Radio Resource Control Protocol (RRC) signaling method.

[0114] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0115] Report upstream data;

[0116] If it is determined that the reported uplink data upload failed, the first information is reported to the network device; wherein, the first information is used to indicate that the uplink data upload failed.

[0117] In this embodiment, the terminal device reports uplink data according to the uplink resources allocated in the first group uplink resource allocation information. If the reported uplink data is detected as successfully uploaded, the terminal device generates first information and sends the first information to the network device to notify the network device that the uplink data upload failed based on the first group uplink resource allocation information. Then, the network device can reallocate uplink resources for the terminal device according to the actual situation to ensure the normal communication of the terminal device.

[0118] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0119] Receive the second group uplink resource allocation information configured by the network device; wherein, the second group uplink resource allocation information is the resource allocation information reconfigured for the terminal device by the network device after receiving the first information.

[0120] Based on the foregoing embodiments, in other embodiments of this application, the first signal includes a resource scheduling request / buffer status report.

[0121] Based on the foregoing embodiments, in other embodiments of this application, the method further includes:

[0122] The uplink resource allocation information for the second group configured by the network device is received via downlink control information (DCI).

[0123] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0124] The resource scheduling method provided in this application involves a terminal device of a target group receiving first group uplink resource allocation information configured by a network device. This first group uplink resource allocation information is obtained by the network device through acquiring first uplink characteristic information, determining an allocation strategy that includes at least the first group uplink resource allocation information based on the first uplink characteristic information, and configuring the target group terminals corresponding to the network device based on the allocation strategy. In this way, the network device determines the allocation strategy corresponding to the target group terminals based on the first uplink characteristic information and configures the first group uplink resource allocation information for the target group terminals according to the allocation strategy. This dynamically adjusts the uplink resources of the target group terminals according to the actual application scenario, solving the problem of resource waste caused by changes in uplink data during current uplink data transmission. This resource scheduling method proposes a semi-static resource allocation method based on actual conditions, reducing the possibility of resource waste and improving resource utilization.

[0125] Based on the foregoing embodiments, this application provides a resource scheduling method for a network device to allocate uplink resources to a group of devices. The method is illustrated using a base station, UE1, UE2, and UE3 as network devices. The corresponding implementation process can be found by referring to [reference needed]. Figure 3 As shown, the specific implementation steps include the following:

[0126] Step a11: The base station uses an AI model to predict group users and group uplink resource allocation information.

[0127] The Artificial Intelligence (AI) model corresponds to the aforementioned first resource allocation model. The group uplink resource allocation information includes one or more statically allocated frequency resource periods, the statically allocated frequency resources within each period, and the MCS used for uplink data transmission. For example, if it is predicted that UE1, UE2, and UE3 belong to the same group of users, corresponding to the aforementioned target group terminals, the base station acquires communication status information of terminal uploaded data collected within a historical time period.

[0128] Step a12: The base station configures the group uplink resource allocation information to UE1, UE2 and UE3 in the group via RRC.

[0129] Step a13: When UE1 has an uplink data packet transmission requirement, it sends the uplink data packet on the uplink group resource.

[0130] Step a14: When the uplink data packet transmission of UE1 fails, UE1 records the data packet transmission failure information.

[0131] In particular, the failure to send uplink data packets for UE1 can be determined, for example, when no ACK information for uplink data packets is received.

[0132] Step a15: UE1 sends a group resource data packet transmission failure message to the base station.

[0133] Step a16: Based on the collected uplink resource transmission information within the group, the base station updates the AI ​​model to obtain new uplink resource allocation information for the group.

[0134] The uplink resource transmission information collected by the base station within the group includes: failure information reported by terminals within the group over a period of time and communication status information corresponding to successful data transmission by other terminals within the group.

[0135] Step a17: The base station reconfigures the new group uplink resource allocation information to UE1 in the group via RRC.

[0136] The communication status information collected in steps a11 and a16 during the historical time period includes at least the following information: the characteristics of uplink data packets of user terminals, including the characteristics of uplink data packets of multiple user terminals over a period of time; and the channel characteristics of user terminals, such as the changing trends of Channel Quality Indicator (CQI) / Signal to Interference plus Noise Ratio (SNIR).

[0137] The process of obtaining the AI ​​model in step a11, i.e., the process of training the model to obtain the AI ​​model, can be referred to... Figure 4 As shown, it includes: model input, model output, calculating the loss value using a loss function based on the model output, and adjusting the adjustable parameters of the model to be trained in reverse. The data transmission path for reverse adjustment can be referenced. Figure 4 The model is shown by the dashed path in the diagram. The model input is the uplink communication status information of multiple user terminals collected historically; the model output is the group uplink resource allocation information; the loss function used is denoted as: LOSS = F(group uplink resource allocation information, transmission result), where the transmission result is the result of whether the corresponding terminal device successfully uploaded data when configuring the group uplink resource allocation information.

[0138] After UE1 executes step a14, this application embodiment also provides a method for fast retransmission of group semi-static resources, the specific implementation process of which can be referred to Figure 5 As shown, it includes at least the following implementation steps:

[0139] Step a18: When UE1's data packet transmission fails, send a scheduling request / buffer status report to the base station.

[0140] Among them, the Scheduling Request (SR) and Buffer Status Report (BSR) carry an identifier indicating that the group resource transmission failed.

[0141] Step a19: After receiving the SR / BSR, the base station determines that the group resource transmission of UE1 has failed and prioritizes reallocating uplink transmission resources for UE1.

[0142] Step a20: The base station reallocates uplink transmission resources to UE1 via DCI.

[0143] Step a21: UE1 retransmits the previously failed uplink data packets to the base station.

[0144] In this way, by predicting groups using AI models and allocating uplink resources for those predicted groups, the transmission latency of uplink data packets is reduced. Furthermore, uplink transmission resources are adjusted according to actual conditions, rather than allocating a fixed amount, thus saving uplink transmission resources. In addition, when data transmission failure occurs after configuring uplink transmission resources for the terminal based on the configured group uplink resource allocation information, a method for fast retransmission of semi-static group resources is proposed. This enables a rapid rollback from semi-static uplink scheduling to dynamic scheduling, ensuring a good user experience.

[0145] Based on the foregoing embodiments, embodiments of this application provide a first resource scheduling device, which is applied to a network device and can be used in various applications.
