Description

Coverage configuration method, device, readable storage medium and computer program product

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese Patent Application No. 202410386479.0 filed in China on April 1, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure belongs to the field of wireless communication technology, and in particular relates to a coverage configuration method, device, readable storage medium, and computer program product. Background Art

[0004] Currently, coverage and capacity optimization (CCO) typically involves identifying problems first and then resolving them. For example, once coverage holes or cell-edge interference are detected, the base station / Operations, Administration, and Maintenance (OAM) team will then develop a strategy to address the issues. OAM configures optional coverage configurations for each Next Generation Radio Access Network (NG-RAN) node. When an NG-RAN node detects a coverage issue or receives a CCO configuration adjustment notification from a neighboring NG-RAN node, it automatically adjusts the CCO configuration. However, this mechanism cannot predict or prevent coverage and capacity issues in advance.

[0005] Considering that coverage and capacity issues can have a significant impact on network performance, the introduction of artificial intelligence (AI) technology can predict CCO issues in advance and propose solutions in advance, which can avoid / reduce the occurrence of coverage and capacity issues and optimize related CCO mechanisms.

[0006] In a centralized unit-distributed unit (CU-DU) split architecture, a next-generation Node B (gNB) can consist of a gNB-CU and one or more gNB-DUs. The gNB-CU and gNB-DU are connected via the F1 interface. The gNB-CU is responsible for handling high-layer protocols, data forwarding, and network management, while the gNB-DU is responsible for handling physical layer functions. Currently, AI / ML training and inference in scenarios involving prediction using AI / machine learning (ML) are performed in the gNB-CU. However, for coverage and capacity optimization scenarios, the gNB-DU needs to send relevant information to the gNB-CU. However, this information contains a large amount of data, and the transmission results in high signaling overhead. Summary of the Invention

[0116] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0117] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects related to each other are in an "or" relationship.

[0118] The following first describes the related technologies related to the present disclosure.

[0119] Coverage and Capacity Optimization (CCO) is one of the optimization methods for radio access networks and a typical use case for Self-Orginazing Networks (SON). The main purpose of CCO is to detect and resolve coverage or capacity issues, such as weak coverage and coverage holes. There is a trade-off between optimizing coverage and capacity: increasing capacity often comes at the expense of reduced coverage, and vice versa. Therefore, optimizing coverage and capacity requires balancing these two key factors.

[0120] CCO allows the system to adapt to changes in traffic (i.e. load and location) and radio environment by automatically adjusting the coverage of the cell. Problems detected by the CCO function include:

[0121] 1. Coverage issues

[0122] Coverage issues focus on scenarios where suboptimal reference signal coverage degrades terminal performance, such as coverage holes and uplink (UL) / downlink (DL) coverage mismatch. It's worth noting that in a network with good cell planning, Mobility Robustness Optimization (MRO) addresses all types of failures caused by poor mobility settings. CCO, on the other hand, addresses failures caused by inappropriate coverage planning.

[0123] 2. Capacity Issues

[0124] When cell or beam capacity is saturated, one or more UEs may experience poor performance. This can occur for a variety of reasons, including: high service demand exceeding the available resources of the cell / beam; a harsh radio environment impacting a large number of user equipment (UEs) (a large number of UEs located at the cell edge cause high interference to other UEs and consume significant resources). It is worth noting that Mobility Load Balancing (MLB) primarily addresses inter-frequency load distribution scenarios. CCO addresses situations where UEs are at the cell / beam edge, where the edge is between cells / beams utilizing the same resources.

[0125] The disclosed embodiments propose a coverage and capacity optimization method involving coverage configuration modification prediction and signaling procedures for CU-DU interactions in scenarios where AI / ML models are deployed on the gNB-DU side. This method fully utilizes data on the gNB-DU side and reduces the signaling overhead required for data transmission.

[0126] The coverage configuration method, device, readable storage medium, and computer program product provided by the embodiments of the present disclosure are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0184] B112, predicting coverage problems or capacity problems within a second time frame;

[0185] Optionally, the coverage problem may be a cell edge problem, etc.; the capacity problem may be a capacity overload, etc.

[0186] B12. Receive a request message sent by a first distribution unit of a first network device, and send first information to the first distribution unit of the first network device according to the request message, wherein the request message is used to request the first information, and the request message is sent by the first distribution unit of the first network device when a coverage problem or a capacity problem is predicted to occur within a first time range;

[0187] It should be noted that this situation refers to the first distributed unit sending a request message to the centralized unit of the first network device when a coverage problem or capacity problem is predicted to occur within the first time range. For example, after the gNB-DU predicts that a coverage problem or capacity problem is about to occur, such as: the cell / beam served by the gNB-DU is overloaded, or there is interference at the serving cell edge (a large number of UEs are located at the cell edge, causing high interference to other UEs and consuming a large amount of resources), etc., it triggers the sending of a request message to the centralized unit.

[0188] Optionally, in one implementation, after receiving the second information sent by the first distribution unit of the first network device, the method further includes at least one of the following:

[0189] C11. Perform coverage adjustment according to the second information;

[0190] It should be noted that, in this case, the centralized unit directly performs coverage adjustment based on the second information fed back by the first distributed unit.

[0191] C12. Send the second information to the second network device;

[0192] Optionally, in this case, the centralized unit needs to send its own second information to the adjacent network devices, so that the adjacent network devices also perform corresponding coverage adjustments.

[0193] Optionally, in one implementation, the method further includes:

[0194] respectively obtaining terminal performance information of the target terminal before and after the coverage configuration is adjusted;

[0195] The target terminal includes at least one of the following:

[0196] D11, a terminal served by the first distribution unit of the first network device;

[0197] It should be noted that, in this case, the first distribution unit feeds back the terminal performance information of the terminals it serves to the central unit.

[0198] D12, terminals served by other distribution units of the first network device except the first distribution unit;

[0199] It should be noted that in this case, the distribution units other than the first distribution unit feed back the terminal performance information of the terminals they serve to the central unit.

[0200] D13, terminals that are served by the first distribution unit of the first network device before the coverage configuration adjustment, and terminals that are served by other distribution units except the first distribution unit of the first network device after the coverage configuration adjustment;

[0201] This situation refers to the situation where the service distribution unit of the terminal whose coverage is adjusted changes, and the terminal performance of the terminal whose service distribution unit needs to be changed by other distribution units is sent to the central unit.

[0202] D14. Adjust the terminal served by the second network device with coverage configuration;

[0203] It should be noted that in this case, the second network device feeds back the terminal performance information of the terminal it serves to the centralized unit. Generally, it can be understood that before and after the coverage configuration adjustment, the terminal has a service adjustment between the first network device and the second network device.

[0204] Optionally, the method further includes:

[0205] Before and / or after the coverage configuration is adjusted, a request message is sent to the terminal, where the request message is used to request the terminal to report terminal performance information, and the request message includes a reporting time.

[0206] It should be noted that for the terminal performance information obtained from the terminal, before the coverage configuration is modified, the centralized unit sends a request message to the terminal and carries the reporting time, and the terminal reports the measurement report before the reporting time; after the coverage configuration is modified, the centralized unit sends a request message to the terminal again, and the terminal reports the relevant measurement report.

[0207] Optionally, in one implementation, the specific implementation of respectively obtaining the terminal performance information of the target terminal before and after the coverage configuration adjustment includes:

[0208] The terminal performance information of the terminal served by the second network device before or after the coverage configuration is adjusted is received and sent by the second network device.

[0209] Optionally, the method further includes:

[0210] Sending instruction information to the second network device, where the instruction information is used to instruct the second network device to feed back terminal performance information after performing coverage adjustment.

[0211] It should be noted that after the centralized unit makes coverage adjustments, some terminals may switch to the second network device. At this time, the centralized unit needs to evaluate the terminal performance of these terminals that have switched. The centralized unit needs to actively obtain the terminal performance information of these terminals from the second network device. After receiving the instruction information from the centralized unit, the second network device will feedback the terminal performance information of the relevant terminals to the centralized unit.

[0212] It should be noted that for terminals that adjust coverage beams / access network devices before and after coverage configuration adjustment, network devices can instruct adjacent network devices to feedback performance information of such terminals after the coverage configuration is modified when exchanging coverage configuration adjustment related information.

[0213] Optionally, the terminal performance information before and after the coverage configuration is modified may be used to compare and evaluate the impact of the network device coverage configuration adjustment on the terminal.

[0214] In summary, the coverage and capacity optimization method proposed in the embodiment of the present disclosure is suitable for scenarios where AI / ML model inference is located on the distribution unit side. The centralized unit sends a first information indicating at least one of layer 3 measurement information, self-optimization network report, minimized drive test report, terminal performance information, wireless resource status of the second distributed unit, and coverage configuration adjustment related information of the target object, so that the distributed unit can obtain relevant information used by the centralized unit for coverage and capacity optimization, thereby reducing the signaling overhead in the coverage configuration process; the centralized unit sends the first information through event triggering or active request by the distributed unit; considering that the coverage configuration modification of the distribution unit may affect the coverage of adjacent network devices, the network devices exchange the second information of the distribution unit to notify the adjacent network devices of the upcoming coverage configuration adjustment before the coverage configuration is modified, so that the adjacent network devices can prepare for the configuration modification in advance; the network device can obtain the terminal performance information of the specified terminal before and after the coverage configuration modification, compare the impact of this coverage configuration modification on the terminal, and consider whether to modify the coverage configuration again.
