Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an uplink transmission resource management method, an uplink data transmission method, and related apparatus. Background Technology

[0002] With the development of communication technology and the increasing number of networked devices, many devices have the need to transmit uplink data.

[0003] Terminal devices need to request uplink transmission resources from the network side to transmit uplink data. A flowchart illustrating the process of requesting uplink transmission resources in related technologies is shown below. Figure 1 As shown, taking a UE (User Equipment) as an example, when a UE needs to transmit data, it needs to transmit an SR (Scheduling Request) to the gNodeB (base station) on its PUCCH (Physical Uplink Control Channel) SRI (Scheduling Request Indication). Upon receiving the SR, the gNodeB will respond by scheduling the UE and allocating a PUSCH (Physical Uplink Shared Channel) for it. The UE will then transmit data and a BSR (Buffer Status Report) on the PUSCH allocated by the gNodeB. The BSR carries the amount of data to be transmitted. If the BSR received by the gNodeB is greater than 0, it understands that the UE still has data to transmit. The gNodeB will continue to schedule uplink transmission resources for the UE and determine the allocated uplink transmission resource amount based on the BSR, enabling the UE to successfully transmit uplink data.

[0004] However, for some terminal devices with low latency requirements, the above uplink data transmission process is difficult to meet the real-time requirements. How to manage uplink transmission resources and perform uplink data transmission to reduce latency needs to be addressed. Summary of the Invention

[0005] This application provides a method, apparatus, and storage medium for inter-cell beam interference coordination. It addresses the problem that existing beam interference coordination schemes can only handle a limited range of interference scenarios, and the coordination effect remains unsatisfactory.

[0006] Firstly, there is an uplink transmission resource management method, the method comprising:

[0007] After the terminal device is connected, uplink transmission resources are allocated and reserved for the terminal device, and the uplink transmission resources are allocated according to the preset minimum resource amount;

[0008] The allocated uplink transmission resources are indicated to the terminal device;

[0009] If the terminal device leaves the network, the uplink transmission resources are reclaimed.

[0010] In this embodiment, after the terminal device accesses the network, the network-side device allocates and reserves uplink transmission resources for the terminal device until the terminal device exits the network. These uplink transmission resources are then reclaimed. Therefore, as long as the terminal device generates uplink data while on the network, it can directly use the reserved uplink transmission resources for uplink control. For example, in a private network scenario, AGV uplink control commands need to be sent intermittently and the data volume is small. Therefore, low-speed uplink transmission resources can avoid the need to execute complex procedures each time. Thus, this application can reduce latency, and the low speed can still meet the uplink requirements of small data volumes for uplink control commands.

[0011] Optionally, the method further includes:

[0012] Receive uplink data sent by the terminal device using the uplink transmission resources, wherein the uplink data includes BSR information;

[0013] If, based on the BSR information, it is determined that the terminal device needs to increase uplink transmission resources and there are sufficient idle uplink transmission resources, then uplink transmission resources are added to the terminal device.

[0014] Therefore, when a terminal device needs to transmit a large amount of uplink data, the uplink transmission resources can be flexibly adjusted according to the requirements of the terminal device to meet its business needs.

[0015] Optionally, the transmission rate includes multiple levels, and determining that the terminal device needs to increase uplink transmission resources based on the BSR information specifically includes:

[0016] The amount of data requested by the terminal device for each of the multiple frame BSRs is obtained; the multiple frame BSRs are BSRs for a specified number of consecutive frames and / or BSRs for a specified duration.

[0017] Based on the amount of data requested by the multiple BSR frames respectively, the required transmission rate of the terminal device is determined, and the transmission rate of the next level is obtained; wherein the transmission rate of the next level is higher than the transmission rate of the current level.

[0018] If the ratio between the transmission rate required by the terminal device and the transmission rate of the next level remains higher than the ratio threshold within a first preset time period, it is determined that the terminal device needs to increase uplink transmission resources.

[0019] In this embodiment of the application, the terminal devices that need to increase uplink transmission resources are screened and identified based on the continuous high-speed requirements of the terminal devices, which can improve the efficiency of uplink transmission resource utilization.

[0020] Optionally, the method further includes:

[0021] If there are insufficient idle uplink transmission resources, reduce the uplink transmission resources of each terminal device to the minimum amount.

[0022] Therefore, when resources are insufficient, uplink transmission resources for each terminal device can be reduced to ensure the normal operation of the entire network. Furthermore, even if uplink transmission resources are reduced due to terminal devices requiring large data transmissions, the service needs of such terminal devices can still be met by continuing to request uplink transmission resources.

[0023] Optionally, determining that the terminal device needs additional uplink transmission resources based on the BSR information specifically includes:

[0024] The amount of data requested by the terminal device for each of the multiple frame BSRs is obtained; the multiple frame BSRs are BSRs of a specified number of consecutive frames and / or BSRs included within a specified duration.

[0025] Based on the amount of data requested by each of the multiple BSR frames, the required transmission rate for the terminal device is determined.

[0026] If the required transmission rate of the terminal device remains higher than the current transmission rate within a second preset time period, it is determined that the terminal device needs to increase uplink transmission resources.

[0027] In this embodiment of the application, the terminal devices that need to increase uplink transmission resources are screened and identified based on the continuous high-speed requirements of the terminal devices, which can improve the efficiency of uplink transmission resource utilization.

[0028] Secondly, this application also provides an uplink data transmission method, the method comprising:

[0029] Retrieve the uplink data to be sent;

[0030] The uplink data is transmitted using uplink transmission resources pre-reserved by the network-side equipment;

[0031] The uplink transmission resources are allocated to the terminal device by the network-side device after the terminal device accesses the network, and the uplink transmission resources are retained until the terminal device leaves the network.

[0032] In this embodiment, the terminal device has available uplink transmission resources whenever it needs to transmit uplink data. In some private network scenarios, for terminal devices that do not continuously transmit uplink data, there is no need to transmit uplink data every time, thus reducing the uplink data transmission delay.

[0033] Optionally, the method further includes:

[0034] If uplink transmission resources are insufficient, a BSR is carried in the uplink data. The BSR includes the amount of data to be transmitted in order to request the network-side device to increase the uplink transmission resources of the terminal device.

[0035] In this implementation, the uplink transmission resources of the terminal device can be flexibly scheduled, thereby meeting the different service needs of the terminal device.

[0036] Optionally, the method further includes:

[0037] Send an access request to the network-side device;

[0038] After accessing the network, the terminal device receives an instruction message sent by the network-side device, which instructs the network-side device to allocate and reserve uplink transmission resources for the terminal device.

[0039] In this implementation, the terminal device can obtain allocated uplink transmission resources upon access, saving the terminal device the process of acquiring uplink transmission resources.

[0055] Optionally, the transmission rate includes multiple levels. The allocation module, specifically used to determine whether the terminal device needs additional uplink transmission resources based on the BSR information, is responsible for:

[0056] The amount of data requested by the terminal device for each of the multiple frame BSRs is obtained; the multiple frame BSRs are BSRs for a specified number of consecutive frames and / or BSRs for a specified duration.

[0057] Based on the amount of data requested by the multiple BSR frames respectively, the required transmission rate of the terminal device is determined, and the transmission rate of the next level is obtained; wherein the transmission rate of the next level is higher than the transmission rate of the current level.

[0058] If the ratio between the transmission rate required by the terminal device and the transmission rate of the next level remains higher than the ratio threshold within a first preset time period, it is determined that the terminal device needs to increase uplink transmission resources.

[0063] Based on the amount of data requested by each of the multiple BSR frames, the required transmission rate for the terminal device is determined.

[0064] If the required transmission rate of the terminal device remains higher than the current transmission rate within a second preset time period, it is determined that the terminal device needs to increase uplink transmission resources.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0098] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0099] First, for ease of understanding, the relevant technology will be analyzed and explained below. It should be understood that the analysis of the relevant technology below is also part of the embodiments of this application.

[0100] In related technologies, when a terminal device needs to perform uplink services, it needs to comply with... Figure 1 The process shown involves sending a Service Request (SR) to the gNodeB. Only after receiving the SR can the gNodeB allocate PUSCH resources to the terminal device. Furthermore, the SR does not carry the terminal device's Base Service Request (BSR) information, so the gNodeB cannot know the amount of data the terminal device needs to upload upon receiving the SR. Additionally, when the gNodeB receives scheduling requests from multiple terminals, it primarily determines the UE's scheduling priority by comprehensively considering channel quality, historical transmission rates, and the service's QCI (QoS Class Identifier) ​​level, and then determines which users to schedule based on this priority.

[0101] Based on the above working mechanism, when the terminal device is not operating continuously, the base station will reclaim the uplink transmission resources of the terminal device once it cannot detect the BSR information of the terminal device. Therefore, each time the terminal device sends uplink data, it needs to perform the following... Figure 1 The SR (Streaming Service) process shown leads to relatively high data latency. This is especially true in private network scenarios, where many command-control terminal devices generate very small amounts of command data and do not continuously send data, but still have high latency requirements. For example, AGVs (Automated Guided Vehicles, equipped with electromagnetic or optical automatic navigation devices) used in factories typically only communicate with the backend control via heartbeats. When control is needed, a few control data messages are sent. Because the AGVs intermittently send uplink data, each time they need to go through the SR and BSR processes, resulting in significant uplink latency.

[0102] Secondly, when the gNodeB receives scheduling requests from multiple terminal devices, if the CQI (Channel Quality Indicator) parameters configured on the terminals are consistent, the gNodeB will maintain a consistent scheduling priority for all terminals. This means that when the overall uplink data volume of the cell is large, newly requesting terminal devices, especially those with poor air interface quality, will not be able to obtain real-time scheduling. However, in private network scenarios, control signal latency requirements are high, necessitating real-time scheduling. Therefore, the latency issue caused by the inability to schedule in real-time with a large number of terminals also needs to be addressed.

[0103] In view of this, embodiments of this application provide an uplink transmission resource management method and an uplink data transmission method. In this embodiment, after a terminal device accesses the network, the network-side device allocates and reserves uplink transmission resources for the terminal device until the terminal device exits the network, at which point these uplink transmission resources are reclaimed. Therefore, as long as the terminal device generates uplink data while on the network, it can directly use the reserved uplink transmission resources for uplink control. To ensure reasonable allocation of uplink transmission resources, in this embodiment, the network-side device can reserve multiple uplink transmission resources for each terminal device, such as one low-speed uplink transmission resource and one high-speed uplink transmission resource. This can meet the different service needs of the terminal device. For example, in a private network scenario, AGV uplink control commands need to be sent intermittently and the data volume is small; therefore, the low-speed uplink transmission resource can avoid executing such commands every time data is sent. Figure 1 The illustrated process reduces latency, and even at low speeds, it can meet the uplink requirements of small data volumes, such as uplink control commands. Therefore, a single low-speed uplink transmission resource can satisfy the low latency and intermittent uplink data transmission needs of this type of terminal device. For example, if a terminal device needs to transmit large amounts of uplink data, it can request the network side to allocate high-speed uplink transmission resources to meet its needs. In this embodiment, low-speed and high-speed uplink transmission resources are represented by resource quantities. For example, supplementing low-speed uplink transmission resources can upgrade them to high-speed uplink transmission resources.

[0104] like Figure 3 As shown, the flowchart of the uplink transmission resource management method provided in the application embodiment includes:

[0105] In step 301, the terminal device sends an access request to the network-side device.

[0106] In step 302, after the terminal device accesses the network, the network-side device allocates and reserves uplink transmission resources for the terminal device, and the uplink transmission resources are allocated according to a preset minimum resource amount.

[0107] In some embodiments, the network-side device can preset multiple uplink schedules with different transmission rates and priorities based on preset rules. For example, two uplink schedules can be configured: one is a default uplink schedule with a high priority and a low transmission rate, and the other is an uplink schedule with a low priority and a high transmission rate. A low transmission rate, such as 500Kbps, is sufficient for everyday scenarios, and the specific transmission rate can be flexibly configured according to the actual application scenario and requirements. A high transmission rate, such as 3Mbps, and the specific transmission rate can be reasonably allocated according to actual service needs, all of which are applicable to the embodiments of this application.

[0108] When there are multiple pre-configured uplink schedules, the network-side equipment can, by default, allocate uplink transmission resources corresponding to the high-priority, low-rate uplink schedule to the terminal device after the terminal device is connected.

[0109] In step 303, the network-side device indicates the allocated uplink transmission resources to the terminal device. Thus, regardless of whether the terminal device performs the following... Figure 1 Both the SR and BSR procedures shown have available uplink transmission resources. Whenever uplink data is generated, the terminal device always has available uplink transmission resources to send the uplink data.

[0110] For example, in step 304, whenever uplink data is generated, the terminal device can obtain the uplink data to be sent; then, it uses the uplink transmission resources reserved in advance by the network-side device to transmit the uplink data to the network-side device.

[0111] When a terminal device sends uplink data, the uplink data can still carry BSR information, which contains the amount of data that the terminal device will transmit.

[0112] Since the uplink transmission resources allocated to terminal devices by default have a low transmission rate, which may not meet the service needs of the terminal devices, the BSR information of the terminal devices can help network-side devices identify the uplink transmission resource requirements of the terminal devices so as to flexibly adjust the uplink transmission rate.

[0113] like Figure 3 As shown, in step 305, the network-side device receives the uplink data sent by the terminal device using the uplink transmission resources.

[0114] In step 306, if the network-side device determines, based on the BSR information, that the terminal device needs additional uplink transmission resources and that there are sufficient idle uplink transmission resources, then it adds uplink transmission resources to the terminal device.

[0115] Therefore, when a terminal device needs to increase its uplink transmission rate, it can request more uplink transmission resources from the network-side device through the BSR information of the uplink data. When the network-side device senses the terminal device's need based on the BSR information, it can add uplink transmission resources to the terminal device to meet its service requirements. Thus, the embodiments of this application not only ensure that the terminal device has basic uplink transmission resources available, but also can flexibly allocate uplink transmission resources to the terminal device by sensing its needs through existing BSR information.

[0116] This application provides several exemplary implementation methods for determining whether a sensing terminal device needs additional uplink transmission resources:

[0117] 1) Example 1 of determining whether to add uplink transmission resources

[0118] In this embodiment of the application, there may be multiple uplink schedules, each with a different transmission rate and a different amount of uplink transmission resources.

[0119] In a simplified implementation, the amount of data indicated by a single BSR message can be read, and the required transmission rate for the terminal device can be calculated based on this data amount. When this transmission rate is higher than the current transmission rate, it indicates that the uplink transmission resources of the terminal device are insufficient, and more uplink transmission resources need to be allocated to the terminal device to improve the uplink transmission rate.

[0120] Since the transmission rate requested in a single instance may only be a momentary demand, in order to rationally allocate uplink transmission resources, the requirements of the terminal device are continuously monitored in this embodiment. When the terminal device continuously needs to increase the uplink transmission rate, uplink transmission resources can be added to the terminal device, that is, uplink scheduling with a lower priority than the current transmission rate can be adopted. In one possible implementation, in order to continuously monitor the terminal device, the amount of data requested by the terminal device in multiple frame BSRs can be obtained. These multiple frame BSRs are BSRs of a specified number of consecutive frames and / or BSRs of a specified consecutive duration. Continuous multiple frame BSRs, especially those of a specified consecutive duration, can well reflect the continuous demands of the terminal device. After obtaining the multiple frame BSRs, the transmission rate required by each frame BSR of the terminal device can be determined based on the amount of data requested by each frame BSR. The ratio of the transmission rate required by each frame BSR to the transmission rate of the next level is determined. If the ratio corresponding to each frame BSR reflects that the terminal device continuously demands an increased transmission rate, then uplink transmission resources need to be added to the terminal device.

[0121] In one possible implementation, for example, if the proportion of each frame's BSR within a specified time period is higher than a proportion threshold, then the uplink transmission resources of the terminal device are increased. For example, if there are two uplink schedules, one for low rate and the other for high rate, and the terminal device is currently using the low-rate uplink schedule, but its BSR indicates a transmission rate that can be as high as 80% of the high rate, and the terminal device requests this transmission rate multiple times, then the terminal device is upgraded to the low-priority high-rate uplink schedule.

[0122] In another possible implementation, for example, if more than half of the BSRs in each frame have a percentage higher than a percentage threshold, then the uplink transmission resources of the terminal device are increased. Alternatively, if the average percentage of BSRs in each frame is higher than the percentage threshold, then the uplink transmission resources of the terminal device are increased.

[0123] In practice, the method for determining whether a terminal device continuously requests an increase in transmission rate based on the BSR can be configured according to specific business needs, and all of these are applicable to the embodiments of this application.

[0124] 2) Example 2 of determining whether to add uplink transmission resources

[0125] In one simple implementation, the transmission rate of uplink resources requested in a single frame BSR can be calculated. If the transmission rate is higher than the current transmission rate, uplink transmission resources can be added to the terminal device.

[0126] Similarly, to rationally allocate and manage uplink transmission resources, it's possible to determine whether the terminal device is continuously requesting an increased transmission rate. A simple implementation is to determine if the terminal device is continuously requesting an increased transmission rate if multiple consecutive BSR requests have transmission rates higher than the current transmission rate, or if multiple consecutive BSR requests have transmission rates higher than the current transmission rate and the difference between them is greater than a preset difference. In this case, uplink transmission resources are allocated to the terminal device.

[0127] It should be noted that the above two embodiments are merely illustrative of how to detect increased uplink transmission resources in terminal devices. During implementation, the scheme can be flexibly configured according to the needs of the business scenario, and all are applicable to the embodiments of this application.

[0128] Furthermore, uplink transmission resources on the network device side are limited. As the number of terminal devices increases, or when multiple terminal devices all require high-speed transmission, uplink transmission resources can easily become strained. Therefore, adding uplink transmission resources for terminal devices can be done when there is sufficient idle uplink transmission resources.

[0129] In step 307, if the terminal device leaves the network, the uplink transmission resources of the terminal device are reclaimed.

[0130] Furthermore, whenever uplink transmission resources are insufficient, the uplink transmission resources of each terminal device can be reduced to the minimum amount. This is equivalent to implementing a default configuration. When certain terminal devices require increased uplink transmission resources due to service demands, adjustments can be made dynamically based on the terminal device's BSR. Therefore, the method for dynamically adjusting uplink resources in this application embodiment is as follows: Figure 4 As shown, for any terminal device, the network-side device can perform the following operations:

[0131] In step 401, after the terminal device is connected, the minimum amount of uplink transmission resources is allocated to the terminal device.

[0132] In step 402, uplink data from the terminal device is received. If it is determined based on the uplink data that uplink transmission resources need to be increased, and if there are sufficient unallocated uplink transmission resources, then uplink transmission resources are increased for the terminal device.

[0133] In step 403, if uplink transmission resources are insufficient at any time, the uplink transmission resources of each terminal device are reduced to the minimum resource amount, and the process returns to step 402.

[0134] In step 404, if the terminal device leaves the network, the uplink transmission resources allocated to the terminal device are reclaimed.

[0135] like Figure 5 As shown, the 5G private network scenario includes AVG vehicle 1, AVG vehicle 2, terminal device 3, and terminal device 4. At time T1, when AVG vehicle 1 and AVG vehicle 2 access the 5G private network, the network-side equipment allocates high-priority but low-uplink transmission rate uplink scheduling to each of them. This uplink scheduling transmission rate is 500Kbps, which meets the daily needs of the AVG vehicles. Then, at time T2, when terminal device 3 accesses the 5G private network, it is also allocated 500Kbps of uplink transmission resources.

[0136] Because the terminal device needs to transmit a large amount of data, terminal device 3 continuously requests large data transmissions in the BSR. At time T3, the network-side device updates the uplink transmission resources of terminal device 3 to high-speed uplink scheduling with low priority and a transmission rate of up to 3Mbps. Similarly, terminal device 4 is also adjusted to high-speed uplink scheduling at time T4 due to service needs.

[0137] At time T5, if the network-side device detects a shortage of uplink transmission resources, it will adjust the uplink scheduling of all four devices—avg car 1, avg car 2, terminal device 3, and terminal device 4—to a low-priority uplink speed of 500Kbps. If terminal device 3 does not have a large uplink data requirement, it will maintain a low uplink speed. However, if terminal device 4 has not finished transmitting its large data volume after the transmission speed decreases, it will continue to request a high transmission speed in the BSR (Background Scheduler). In the subsequent time T6, the network-side device will readjust the uplink scheduling for terminal device 4 to a low-priority, high-speed speed based on its BSR.

[0138] Furthermore, for devices maintaining low speeds, even if AVG vehicle 1, AVG vehicle 24, and terminal device 3 have no uplink data, the network-side devices will reserve uplink transmission resources for themselves. Once data needs to be transmitted uplink, the reserved uplink transmission resources can be used immediately to transmit data without executing the SR and BSR procedures, thereby reducing latency compared to existing technologies.
