Description

Communication method, device and system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 21, 2023, with application number 202311557554.7 and application name “Communication Methods, Devices and Systems”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and more specifically, to a communication method, device, and system. Background Art

[0003] Coverage and capacity optimization (CCO) is an important network self-optimization function that can be used to detect and resolve one or both of coverage and capacity issues in a cell.

[0004] When a CCO problem is detected in a cell, the network device to which the cell belongs can resolve the CCO problem in the cell by adjusting the configuration of the cell. The configuration includes the coverage configuration of the cell and the coverage configuration of the cell's synchronization signal physical broadcast channel block (also referred to as synchronization signal block) (SSB). After completing the configuration adjustment, the network device to which the cell belongs sends the adjusted configuration of the cell to the adjacent network device, and the adjacent network device adjusts the configuration of the cell belonging to the adjacent network device according to the adjusted configuration.

[0005] However, the above solution may not bring higher gain to the network device that detects the CCO problem and solves the CCO problem. Summary of the Invention

[0006] The present application provides a communication method, apparatus, and system that can support a network device that detects a CCO problem and solve the CCO problem to bring higher gain.

[0007] In a first aspect, a communication method is provided, comprising: receiving first information from a first network device, the first information indicating information about a CCO problem of a first cell, the first cell belonging to the first network device; and sending second information to the first network device in response to the first information, the second information indicating a handling strategy for the CCO problem of the first cell.

[0008] The above method can be applied to the second network device. It is understood that the execution entity of the solution described in the first aspect can be the second network device, or a module of the second network device (such as a chip system, etc.), or a logical node, logic module, or software that can implement all or part of the functions of the second network device, without limitation. For ease of description, the following description uses the second network device as an example.

[0009] The sending of the second information in response to the first information may include: the second network device determining the second information based on the first information, or the second network device referencing the first information when determining the second information. In this manner, after receiving the first information, the second network device sends the second information to the first network device, thereby helping the first network device determine a strategy for handling the CCO issue in the first cell.

[0010] In one possible implementation, the second information indicating a handling strategy for the CCO problem of the first cell may include: after receiving the second information, the first network device may determine a handling strategy for the CCO problem of the first cell, for example, the first network device determining an appropriate configuration adjustment solution for the first cell (the appropriate configuration adjustment solution may eliminate the need for the first network device to significantly adjust the configuration of the first cell), or the first network device determining that the CCO problem of the first cell does not need to be resolved. In this way, the above solution can bring higher benefits to the first network device in resolving the CCO problem.

[0011] In the above solution, after the first network device determines that a CCO problem exists in the first cell, it can send information about the CCO problem in the first cell to the second network device. The second network device can, based on the information, instruct the first network device on a handling strategy for the CCO problem in the first cell, and the first network device handles the CCO problem in the first cell according to the handling strategy. For example, the first network device determines an appropriate configuration adjustment solution for the first cell (the appropriate configuration adjustment solution can eliminate the need for the first network device to make significant adjustments to the configuration of the first cell), or the first network device determines that there is no need to resolve the CCO problem in the first cell.

[0012] The above solution can bring greater benefits to the first network device in solving the CCO problem of the first cell. For example, the second network device solves the CCO problem of the first cell, and the first network device does not need to solve the CCO problem of the first cell; for example, the second network device helps the first network device determine a suitable configuration adjustment solution, and the first network device can adjust the configuration of the first cell in a lower power consumption manner to solve the CCO problem of the first cell.

[0013] In the first aspect, the method may further include: receiving third information, the third information including the adjusted configuration information of the cell.

[0014] The cell mentioned above may be the first cell, or may be another cell belonging to the first network device, for example, a neighboring cell of the first cell. By adjusting the configuration of the cell, the first network device may solve the CCO problem of the first cell.

[0015] After the first network device adjusts the configuration of the cell, it can send the adjusted configuration information of the cell to the second network device. The second network device can adaptively adjust the configuration of the cell belonging to the second network device according to the adjusted configuration information of the cell, so as to better communicate with the first network device.

[0016] In a second aspect, a communication method is provided, including: sending first information to a second network device, the first information indicating information about a CCO problem of a first cell, the first cell belonging to the first network device; receiving second information from the second network device, the second information indicating a processing strategy for the CCO problem of the first cell.

[0017] The above method can be applied to the first network device. It is understood that the execution entity of the solution described in the second aspect can be the first network device, or a module of the first network device (such as a chip system, etc.), or a logical node, logic module, or software that can implement all or part of the functions of the first network device, without limitation. For ease of description, the following description uses the first network device as an example.

[0018] In the above solution, after the first network device determines that a CCO problem exists in the first cell, it can send information about the CCO problem in the first cell to the second network device. The second network device can, based on the information, instruct the first network device on a handling strategy for the CCO problem in the first cell, and the first network device handles the CCO problem in the first cell according to the handling strategy. For example, the first network device determines an appropriate configuration adjustment solution for the first cell (the appropriate configuration adjustment solution can eliminate the need for the first network device to make significant adjustments to the configuration of the first cell), or the first network device determines that there is no need to resolve the CCO problem in the first cell.

[0019] The above solution can bring greater benefits to the first network device in solving the CCO problem of the first cell. For example, the second network device solves the CCO problem of the first cell, and the first network device does not need to solve the CCO problem of the first cell; for example, the second network device helps the first network device determine a suitable configuration adjustment solution, and the first network device can adjust the configuration of the first cell in a lower power consumption manner to solve the CCO problem of the first cell.

[0020] In combination with the solution described in any aspect of the first aspect and the second aspect, the first information includes at least one of the following: identification information of the first cell; the type of CCO problem of the first cell; or information of the terminal device served by the first cell.

[0021] In one example, when the first information includes identification information of the first cell, the identification information of the first cell can be used to indicate to the second network device that a CCO problem exists in the first cell. For example, embodiments of the present application can support a protocol agreement or configuration in which, when the first network device sends identification information of a certain cell to the second network device, the identification information of the cell can be used to indicate that a CCO problem exists in the cell.

[0022] In one example, when the first information includes the type of CCO problem in the first cell, the second network device determines that a cell in the first network device has a CCO problem and adjusts the configuration of one or more cells under the second network device's jurisdiction that are adjacent to the first cell. In this way, the first network device can resolve the CCO problem in the first cell without adjusting the configuration of the first cell, which helps reduce power consumption of the first network device and thus brings greater benefits.

[0023] In one example, when the first information includes information about a terminal device, the information about the terminal device can be used to indicate that a CCO problem exists in a cell in the first network device. For example, embodiments of the present application can support a protocol agreement or configuration in which, when the first network device sends information about the terminal device to the second network device, the information about the terminal device can be used to indicate that a CCO problem exists in a cell in the first network device.

[0024] Through one or more of the above, the second network device can obtain or determine information about the CCO problem of the first cell.

[0025] In combination with the solution described in any aspect of the first aspect and the second aspect, the first information also includes at least one of the following: identification information of the second cell, the second cell belongs to the second network device; or, at least one first configuration information, the first configuration information indicates configuration adjustment of the second cell.

[0026] The above-mentioned second cell is a neighboring cell of the first cell.

[0027] The second network device can adjust the configuration of the second cell according to one or two of the above items, so as to solve the CCO problem of the first cell, thereby bringing higher gains to the first network device in solving the CCO problem of the first cell, for example, saving the power consumption of the first network device.

[0028] In combination with the scheme described in any aspect of the first aspect and the second aspect, the information of the terminal device includes at least one of the following: identification information; measurement results of the first cell; measurement results of the synchronization signal block in the first cell; measurement results of the second cell; measurement results of the synchronization signal block in the second cell; measurement results of the third cell, the third cell belongs to the first network device; or, measurement results of the synchronization signal block in the third cell.

[0029] The second cell and the third cell are neighboring cells of the first cell. The second cell belongs to the second network device, and the third cell belongs to the first network device.

[0030] The second network device can determine that the first cell has a CCO problem based on one or more of the above-mentioned items, and then determine to adjust the configuration of the second cell. In this way, the CCO problem of the first cell can be solved, thereby bringing higher gains to the first network device in solving the CCO problem of the first cell, for example, saving the power consumption of the first network device.

[0031] In combination with the scheme described in any aspect of the first aspect and the second aspect, the first configuration information includes at least one of the following: the adjusted cell coverage status parameter of the second cell; the adjusted synchronization signal block coverage status parameter of the second cell; or the adjusted mobility parameter of the second cell and the identification information of the neighboring area of ​​the second cell.

[0032] The second network device adjusts the configuration of the second cell according to one or more of the above items, so as to solve the CCO problem of the first cell, thereby bringing higher gains to the first network device in solving the CCO problem of the first cell, for example, saving the power consumption of the first network device.

[0033] In combination with the scheme described in any aspect of the first aspect and the second aspect, the second information includes the configuration information of the adjusted second cell, and the configuration information of the adjusted second cell includes at least one of the following: identification information of the second cell; cell coverage status parameters of the adjusted second cell; synchronization signal block coverage status parameters of the adjusted second cell; or, the mobility parameters of the adjusted second cell and identification information of the neighboring cells of the second cell.

[0034] The first network device can determine, based on one or more of the above, that the second network device has adjusted the configuration of the second cell, and determine that the CCO problem of the first cell can be solved after the configuration of the second cell is adjusted. In this way, the first network device can determine, based on the second information, that the first network device does not need to solve the CCO problem of the first cell, which can save power consumption of the first network device, thereby bringing higher gains for the first network device to solve the CCO problem of the first cell.

[0035] In combination with the solution described in any aspect of the first aspect and the second aspect, the second information includes a reason value for indicating a configuration adjustment failure of the second cell.

[0036] Optionally, the second information may be used to indicate that the configuration adjustment of the second cell has failed.

[0037] In this way, the first network device can determine, based on the second information, that the second network device has failed to adjust the configuration of the second cell, and can thereby determine that the first network device needs to resolve the CCO problem of the first cell by itself.

[0038] In combination with the solution described in any aspect of the first aspect and the second aspect, the above-mentioned cause value includes at least one of the following: no suitable configuration, or configuration adjustment is not supported.

[0039] For example, the reason value is configuration adjustment not supported, which means that the second network device uses a fixed cell configuration and cannot be adjusted. When the first network device subsequently finds that the cell has a CCO problem, it will no longer send the first information to the first network device.

[0040] For example, the reason value is "no suitable configuration", which means that the second network device supports cell configuration adjustment, but no suitable configuration was found at this time. When the first network device subsequently finds that the cell has a CCO problem, it can still send the first information to the second network device.

[0041] In combination with the scheme described in any aspect of the first aspect and the second aspect, the first information also includes at least one of the following: at least one second configuration information, the second configuration information indicates a configuration adjustment for the cell; or, at least one second configuration information and an evaluation indicator, the evaluation indicator indicates an indicator used when evaluating at least one second configuration information.

[0042] Optionally, the second configuration information may indicate a configuration adjustment that may be taken by the cell. The cell may be the first cell, or a neighboring cell of the first cell, such as a third cell, etc., which is not limited.

[0043] Optionally, the above-mentioned evaluation indicator may also be a feedback indicator, which is used to indicate an indicator used when providing feedback or evaluating the corresponding second configuration information.

[0044] The second network device can evaluate the second configuration information based on one or more of the above-mentioned items, which is helpful in helping the first network device determine a suitable configuration adjustment plan. The suitable configuration adjustment plan can enable the first network device to avoid making major adjustments to the configuration of the first cell, etc., which can bring higher gains to the first network device in solving the CCO problem of the first cell.

[0045] In combination with the scheme described in any aspect of the first aspect and the second aspect, the second configuration information includes at least one of the following groups: the identification information of the cell, the adjusted cell coverage status parameters of the cell; the identification information of the cell, the adjusted synchronization signal block coverage status parameters of the cell; or, the identification information of the cell, the adjusted mobility parameters of the cell and the identification information of the neighboring cells of the cell.

[0046] The above-mentioned cell may be the first cell, or a neighboring cell of the first cell, for example, the third cell, etc., and this is not limited.

[0047] The second network device may determine the configuration adjustment that the first network device may make to the first cell, and thus may help the first network device determine an appropriate configuration adjustment.

[0048] In combination with the scheme described in any aspect of the first aspect and the second aspect, the evaluation index includes at least one of the following information: at least one third configuration information, the third configuration information is used to adjust the configuration of the second cell, and at least one third configuration information corresponds one-to-one with at least one second configuration information; at least one prediction information, at least one prediction information corresponds one-to-one with at least one second configuration information, and the prediction information is used to predict the device performance under the corresponding first configuration information; or, in at least one second configuration information, configuration information acceptable to the second network device.

[0049] Optionally, the third configuration information may indicate configuration adjustments that may be taken by the second cell under the corresponding second configuration information.

[0050] Optionally, the configuration information acceptable to the second network device may also be understood as configuration information recommended by the second network device.

[0051] Through one or more of the above, the second network device reasonably evaluates each second configuration information, thereby helping the first network device to determine a suitable configuration adjustment solution.

[0052] In combination with the scheme described in any aspect of the first aspect and the second aspect, the prediction information includes at least one of the following: a prediction of the measurement results of the cell; a prediction of the measurement results of the synchronization signal block in the cell; a prediction of the measurement results of the cell; a prediction of the measurement results of the synchronization signal block in the cell; or, first indication information, the first indication information indicates whether the cell will have a CCO problem.

[0053] Through one or more of the above, the second network device can reasonably evaluate each second configuration information, thereby helping the first network device determine an appropriate configuration adjustment solution. In combination with the solution described in any of the first and second aspects, the second information includes at least one of the following: second indication information, the second indication information is used to indicate whether to accept at least one second configuration information; third indication information, the third indication information is used to indicate acceptable configuration information in at least one second configuration information; or at least one evaluation result, at least one evaluation result has a one-to-one correspondence with at least one second configuration information, and the evaluation result corresponds to the evaluation indicator.

[0054] The above evaluation result is obtained by evaluating the corresponding second configuration information according to the evaluation index.

[0055] The first network device can determine appropriate second configuration information in at least one second configuration information based on one or more of the above-mentioned items, and adjust the configuration of the cell based on the appropriate second configuration information, thereby solving the CCO problem of the first cell and bringing higher gains. For example, the power consumption of the first network device is lower, etc.

[0056] In the solution described in any of the first and second aspects, the second information includes a reason value for indicating evaluation failure.

[0057] Optionally, the second information mentioned above may indicate that the evaluation has failed.

[0058] The first network device may determine, based on the second information, that the second network device is unable to evaluate the second configuration information, and the first network device may determine appropriate second configuration information on its own.

[0059] In combination with the solution described in any aspect of the first aspect and the second aspect, the cause value includes at least one of the following: no evaluation result is obtained; or evaluation of at least one second configuration information is not supported.

[0060] For example, when the reason value is "no evaluation result obtained," it may indicate that the second network device has the evaluation function but did not obtain a suitable evaluation result this time. If the first network device subsequently discovers a CCO problem, it may still send the first information to the second network device.

[0061] For example, when the cause value indicates that the evaluation of the at least one second configuration information is not supported, it may indicate that the second network device does not have the evaluation function. When the first network device subsequently discovers a CCO problem, it will no longer send the first information to the second network device.

Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0106] 4. The terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or apparatus.

[0107] 5. In this application, "used to indicate" can be understood as "enabling," and "enabling" can include direct enabling and indirect enabling. When describing that certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and does not necessarily mean that the information contains A.

[0108] The information enabled by the information is called information to be enabled. In the specific implementation process, there are many ways to enable the enabled information, such as but not limited to, directly enabling the information to be enabled, such as the information to be enabled itself or the index of the information to be enabled. The information to be enabled can also be indirectly enabled by enabling other information, wherein there is an association between the other information and the information to be enabled. It is also possible to enable only a part of the information to be enabled, while the other parts of the information to be enabled are known or agreed in advance. For example, it is also possible to enable specific information with the help of the arrangement order of each piece of information agreed in advance (such as specified in the protocol), thereby reducing the enabling overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and enable them uniformly to reduce the enabling overhead caused by enabling the same information separately.

[0109] 6. In this application, "pre-configuration" may include pre-definition, such as protocol definition. "Pre-definition" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., including each network element).

For example, A / B can mean A or B. “And / or” in this application is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0114] First, a communication system to which the embodiments of the present application are applicable is described.

[0115] Figure 1 is a schematic diagram of a communication system applicable to embodiments of the present application. As shown in Figure 1 , the communication system includes: network device 110, network device 120, and terminal device 130. Terminal device 130 is within the coverage area of ​​network device 110. For example, network device 110 provides network access services for terminal device 130.

[0116] In actual applications, the communication system shown in FIG1 may further include a larger number of terminal devices and network devices, and may also include other devices, such as core network devices, etc., without limitation thereto.

[0117] In an embodiment of the present application, a terminal device is a device with wireless transceiver capabilities, which may refer to user equipment (UE), access terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user device.

[0118] In the embodiment of the present application, the terminal device may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a customer-premises equipment (CPE), a smart point of sale (POS) machine, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a communication device carried on a high-altitude aircraft, a wearable device, a drone, a robot, a terminal in device-to-device (D2D) communication, a terminal in vehicle-to-everything (V2X), a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a remote medical device, or a similar device. There is no restriction on wireless terminals in medical, smart grid, transportation safety, smart city, smart home, or terminal devices in communication networks evolved after 5G.

[0119] In the embodiment of the present application, the terminal device may also be a device with communication functions in the 6G communication system, without limiting the form or type of the terminal device in the 6G and other future communication systems.

[0120] In the embodiments of the present application, the communication device used to implement the functions of the terminal device can be the terminal device, or it can be a device that can support the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the present application, the chip system can be composed of a chip or include a chip and other discrete devices.

[0121] In the embodiment of the present application, the network device is a device with wireless transceiver functions, which is used to communicate with the terminal device. The network device can be a node in the radio access network (RAN), which can also be called a base station, or a RAN node. It can be an evolved Node B (eNB or eNodeB) of LTE; or a base station of a 5G network such as gNodeB (gNB) or a base station in a public land mobile network (PLMN) evolved after 5G, a broadband network gateway (BNG), an aggregation switch or the 3GPP (the 3GPP) rd generation partnership project, 3GPP) network equipment, etc.

[0122] The RAN can be configured as a RAN defined by the 3GPP protocol, an open radio access network (O-RAN), or a cloud radio access network (C-RAN). Network equipment can also include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, transmission points (transmitting and receiving points, TRPs), transmission points (transmitting points, TPs), mobile switching centers, and devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, network equipment in non-terrestrial networks (NTNs), etc., without specific limitation.

[0123] In an embodiment of the present application, the network device may further include a network element or module that implements part of the functions of the base station, for example, one or more of the following: a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). Optionally, the CU can be further separated into a CU-control plane (CP) and a CU-user plane (UP). The functions of the CU and DU can be implemented by different network elements, or simultaneously by the baseband unit (BBU) of the base station. The function of the RU can be implemented by the radio frequency equipment of the base station. For example, the radio frequency equipment of the base station may be a remote radio unit (RRU), a pico remote radio unit (pRRU), an active antenna unit (AAU), or other units, modules or devices with radio frequency processing functions. The communication interface protocol between the BBU and the radio frequency equipment can be a common public radio interface (CPRI) interface protocol, an enhanced common public radio interface (eCPRI) interface protocol, or a fronthaul interface protocol between the DU and RU in the O-RAN system, etc., without limitation.

[0124] In different communication systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0125] In the embodiment of the present application, the network device may also be a device with communication functions in the 6G communication system, without limiting the form or type of the network device in the 6G and other future communication systems.

[0126] In the embodiments of the present application, the communication device used to implement the functions of the network device can be a network device, or a device that can support the network device to implement the functions, such as a chip system. The device can be installed in the network device or used in conjunction with the network device. The chip system in the embodiments of the present application can be composed of a chip, or can include a chip and other discrete devices.

[0127] The aforementioned network equipment may include a baseband device and a radio frequency device. The baseband device may be implemented by a single node or by multiple nodes. The radio frequency device may be independently implemented remotely from the baseband device or integrated into the baseband device, or some functions may be integrated independently and some functions may be integrated into the baseband device. For example, in an LTE communication system, the network equipment includes a baseband device and a radio frequency device. The radio frequency device may be remotely located relative to the baseband device, such as an RRU, which is a remote radio unit located relative to the BBU.

[0128] The communication between network equipment and terminal equipment follows a certain protocol layer structure. For example, the control plane protocol layer structure may include the functions of protocol layers such as the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the media access control (MAC) layer and the physical layer; the user plane protocol layer structure may include the functions of protocol layers such as the PDCP layer, the RLC layer, the MAC layer and the physical layer; in one possible implementation, a service data adaptation protocol (SDAP) layer may also be included above the PDCP layer.

[0129] A network device may implement the functions of protocol layers such as RRC, PDCP, RLC, and MAC by a single node, or may implement the functions of these protocol layers by multiple nodes. For example, in an evolutionary structure, a network device includes a CU and DU, and multiple DUs are centrally controlled by a single CU. For example, the CU and DU may be divided based on the protocol layers of the wireless network, such as the PDCP layer and above, which are located in the CU, while the functions of protocol layers below the PDCP layer, such as the RLC layer and MAC layer, are located in the DU.

[0130] This protocol layer division is merely an example. Division can also be performed at other protocol layers, such as the RLC layer, where functions at and above the RLC layer are located in the CU, while functions at layers below the RLC layer are located in the DU. Alternatively, division can be performed within a specific protocol layer, such as where some functions at the RLC layer and functions at layers above the RLC layer are located in the CU, while the remaining functions at the RLC layer and functions at layers below the RLC layer are located in the DU. Furthermore, division can be performed in other ways, such as by latency, where functions that require processing time to meet latency requirements are located in the DU, while functions that do not require latency requirements are located in the CU.

[0131] In addition, the radio frequency device can be independently integrated and not placed in the DU, or it can be integrated in the DU, or part of it can be remotely located and part of it can be integrated in the DU. There is no limitation here.

[0132] The network architecture and service scenarios described in this application are intended to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute a limitation on the technical solutions provided by this application. Persons skilled in the art will appreciate that, with the evolution of communication network architectures and the emergence of new service scenarios, the technical solutions provided in this application are equally applicable to similar technical problems. For example, this application may be applicable to V2X scenarios.

[0133] To facilitate understanding and explanation, the relevant terms involved in the embodiments of the present application are briefly described below.

[0134] Cell coverage issues: This refers to weak coverage or coverage holes at the cell edge. See Figure 2 for an illustration of cell coverage issues.

[0135] Figure 2 is a schematic diagram of a cell coverage problem. As shown in Figure 2, cell 1 is a cell of the network device 110, the terminal device 130 is located in cell 1, and cell 2 is a cell of the network device 120. Cell 2 is a neighboring cell (or adjacent cell) of cell 1. The terminal device 130 measures cell 1 and obtains or acquires the reference signal received power (RSRP) of cell 1 (it can also be a measurement result of cell 1, where RSRP is an example of a measurement result of a cell). When the RSRP of cell 1 is less than 110dBm (as an example, not a limitation), the network device 110 may deem that a coverage problem occurs or exists in cell 1.

[0136] The terminal device 130 may also measure cell 2, obtain or acquire the RSRP of cell 2 (or obtain the measurement result of cell 2), and report the RSRP of cell 2 to the network device 110. The network device 110 may determine whether cell 1 has or has a coverage problem based on the RSRP of cell 2. For example, when the RSRP of cell 2 is lower than a threshold (e.g., 10 dBm), the network device 110 determines that cell 1 has a coverage problem.

[0137] Cell capacity problem: refers to the low capacity (or user rate) at the cell edge. For a description of the cell capacity problem, see Figure 3.

[0138] Figure 3 is a schematic diagram illustrating a cell capacity problem. As shown in Figure 3, cell 1 is a cell of network device 110, cell 2 is a cell of network device 120, cell 2 is a neighboring cell of cell 1, and terminal device 130 is located within cell 1. Terminal device 130 is susceptible to the impact of cell 2. Terminal device 130 measures cell 1 and cell 2, obtains or acquires the RSRP of cell 1 and the RSRP of cell 2, and reports the RSRP of cell 1 and cell 2 to network device 110. When the difference between the RSRP of cell 1 and the RSRP of cell 2 is less than a threshold (e.g., 6 dBm), network device 110 may determine that a capacity problem exists or is occurring in cell 1.

[0139] In the embodiment of the present application, the capacity problem of cell 1 may be that the coverage of cell 2 is too large, causing significant interference to edge users of cell 1. In addition, the capacity problem of a cell may also be expressed as a cell edge capacity problem of the cell.

[0140] In the embodiment of the present application, the coverage problem and the capacity problem of the cell can be collectively referred to as the CCO problem of the cell. Unless otherwise specified, the following will not distinguish the types of CCO problems of the cell.

[0141] When the network device 110 detects that a CCO problem exists or occurs in cell 1, the network device 110 may adjust the configuration of cell 1 (or cell configuration, including but not limited to: cell coverage, SSB coverage, mobility parameters, etc.), for example, by changing the downlink transmission power of cell 1, the tilt angle and azimuth angle of the antenna, etc. to enhance the coverage of cell 1, thereby solving the CCO problem of cell 1.

[0142] However, the above solution may not bring greater benefits to the network device 110 in solving the CCO problem of cell 1 .

[0143] In view of this, the present application provides a communication method, apparatus, and system that can support a network device that detects a CCO problem and solve the CCO problem to bring higher gain.

[0144] The following describes the communication method, device, and system according to the embodiments of the present application in conjunction with the accompanying drawings.

[0145] FIG4 is a schematic diagram of an interaction flow of a communication method according to an embodiment of the present application. As shown in FIG4 , the method includes:

[0146] S401 : Network device 110 (eg, a first network device) sends information 1 (eg, first information) to network device 120 (eg, a second network device).

[0147] Accordingly, the network device 120 receives information 1. The information 1 indicates information about the CCO problem of cell 1 (eg, the first cell).

[0148] The network device 120 can determine or obtain information about the CCO problem of cell 1 based on information 1. For example:

[0149] Information 1 indicates information about the CCO problem of cell 1 (such as CCO issue / CCO problem / CCO matter / CCO trouble, etc.);

[0150] Information 1 indicates information related to the CCO problem of cell 1;

[0151] Information 1 includes or carries information about a CCO problem in cell 1;

[0152] Information 1 includes or carries information related to the CCO problem of cell 1; or,

[0153] Information 1 indicates one or more processing strategies for solving the CCO problem of cell 1. Here, strategy can also be understood as alternative expressions such as solution or method, which is not limited to this.

[0154] In summary, the network device 120 may determine the information about the CCO problem of cell 1 based on one or more of the above items.

[0155] It should be noted that other expressions of information 1 may be CCO information, CCO feedback information, CCO problem information, or CCO feedback information of a cell, etc., which are not limited thereto.

[0156] In one possible implementation, network device 120 may determine, based on information 1, that cell 1 has a CCO problem. Based on this, network device 120 may provide assistance in resolving the CCO problem in cell 1, for example, by adjusting the configuration of one or more cells belonging to network device 120 that are adjacent to cell 1; for example, this may provide a reference for network device 110 to determine an appropriate configuration adjustment solution. Details are described below.

[0157] In the embodiment of the present application, cell 1 belongs to network device 110. The term "belongs" can be understood as: cell 1 is a cell of network device 110, or cell 1 is one of multiple cells managed by network device 110. In summary, cell 1 and network device 110 have an affiliation or subordinate relationship.

[0158] In the embodiment of the present application, the CCO problem of cell 1 can be understood as: a CCO problem existing in cell 1; or a CCO problem occurring in cell 1; or a CCO problem in cell 1, etc. For ease of description, the following description takes the CCO problem of cell 1 as an example, but other expressions are not limited.

[0159] In one possible implementation, the network device 110 may determine whether the cell 1 has a CCO problem by one or more of the following:

[0160] In cell 1, the RSRP of cell 1 measured by a terminal device (for example, terminal device 130) is less than a threshold value (for example, 110 dBm);

[0161] In cell 1, the RSRP of cell 1 measured by a certain number of terminal devices (for example, 10% of the terminal devices) is less than a threshold value (for example, 110 dBm);

[0162] In cell 1, a difference between the RSRP of cell 1 measured by a terminal device (e.g., terminal device 130) and the RSRP of a measured neighboring cell (e.g., cell 2 (e.g., the second cell) or cell 3 (e.g., the third cell), where cell 3 is a cell of network device 110) is less than a threshold value (e.g., 6 dBm); or,

[0163] In cell 1, a difference between the RSRP of cell 1 measured by a certain number of terminal devices (for example, 10% of the terminal devices) and the RSRP of a neighboring cell measured is less than a threshold value (for example, 6 dBm).

[0164] Exemplarily, terminal device 130 measures cell 1, obtains the RSRP of cell 1, and reports the RSRP of cell 1 to network device 110. When the RSRP of cell 1 is less than a threshold, network device 110 determines that a CCO problem (such as a coverage problem) exists or occurs in cell 1.

[0165] Exemplarily, the terminal device 130 measures cell 1 and cell 2 (cell 1 and cell 3 may also be measured, without limitation), obtains the RSRP of cell 1 and the RSRP of cell 2, and reports the RSRP of cell 1 and the RSRP of cell 2 to the network device 110. When the difference between the RSRP of cell 1 and the RSRP of cell 2 is less than a threshold, the network device 110 determines that a CCO problem (such as a capacity problem) exists or occurs in cell 1.

[0166] Through the above-listed conditions, network device 110 can determine whether a CCO problem exists in cell 1 and the type of CCO problem. For example, if one or both of the first two conditions are met, it can be determined that cell 1 has a coverage problem, and if one or both of the last two conditions are met, it can be determined that cell 1 has a capacity problem.

[0167] It should be noted that the above-mentioned conditions are examples and are not intended to be final limitations.

[0168] In one possible implementation, information 1 may include at least one of the following:

[0169] identification information of cell 1;

[0170] The type of CCO problem in cell 1; or,

[0171] Information of terminal devices served by cell 1.

[0172] In one example, information 1 includes identification information of cell 1, and the identification information of cell 1 can be used to indicate to network device 120 that a CCO problem exists in cell 1. For example, an embodiment of the present application can support a protocol agreement or configure that when network device 110 sends identification information of a certain cell to network device 120, the identification information of the cell can be used to indicate that a CCO problem exists in the cell.

[0173] Based on the identification information of cell 1, network device 120 determines that cell 1 has a CCO problem. It then identifies one or more cells under the jurisdiction of network device 120 that are adjacent to cell 1. Taking cell 2 as an example, network device 120 resolves the CCO problem in cell 1 by adjusting the configuration of cell 2. In this way, network device 110 can resolve the CCO problem in cell 1 without having to adjust the configuration of cell 1. This helps reduce the power consumption of network device 110, thereby achieving greater benefits.

[0174] The identification information of cell 1 may include an identifier of cell 1, such as a cell global identifier (CGI), a physical cell ID (PCI), or other identifiers, and may also include other information for distinguishing cells, such as an index.

[0175] It should be noted that the configuration adjustment can be understood as: adjusting the coverage status of the cell, adjusting the coverage status of the SSB in the cell, adjusting the mobility parameters of the cell, etc., which will be described in detail below.

[0176] In one example, information 1 includes the type of CCO problem in cell 1. Network device 120 determines that a cell in network device 110 has a CCO problem and adjusts the configuration of one or more cells adjacent to cell 1 under the management of network device 120. In this way, network device 110 can resolve the CCO problem in cell 1 without adjusting the configuration of cell 1, which helps reduce power consumption of network device 110 and thus brings greater benefits.

[0177] The types of CCO issues in cell 1 can include coverage issues and capacity issues. Distinguishing the types of CCO issues facilitates network device 120 in determining an appropriate strategy for resolving the CCO issue in cell 1. For example, for coverage issues, network device 120 can resolve the CCO issue in cell 1 by enhancing the coverage of cell 2. For capacity issues, network device 120 can resolve the CCO issue in cell 1 by reducing the coverage of cell 2.

[0178] In one example, information 1 includes information about a terminal device served by cell 1, and the information about the terminal device can be used to indicate that a CCO problem exists in a certain cell in network device 110. For example, an embodiment of the present application can support a protocol agreement or configure network device 110 to send information about a terminal device to network device 120, and the information about the terminal device can be used to indicate that a CCO problem exists in a certain cell in network device 110.

[0179] Based on the determination that a cell in network device 110 has a CCO problem, network device 120 can adjust the configuration of one or more cells under the network device 120's jurisdiction, for example, to enhance the coverage of cell 2. In this way, network device 110 can resolve the CCO problem in cell 1 without having to adjust the configuration of cell 1, which helps reduce power consumption of network device 110.

[0180] The above-mentioned terminal device information may be understood as information of one or more terminal devices. The one or more terminal devices may all be located in cell 1, or may be located in cell 1 and another cell (eg, cell 3).

[0181] Through one or more of the above, the network device 120 can obtain or determine information about the CCO problem of cell 1.

[0182] Optionally, the above-mentioned one or more terminal devices may include all terminal devices in cell 1, or may only include terminal devices in cell 1 that are related to the CCO problem (for example, terminal devices whose measured RSRP of cell 1 is less than a threshold).

[0183] In one possible implementation, the information of the terminal device served by cell 1 may include at least one of the following:

[0184] Identification information;

[0185] Measurement results for cell 1;

[0186] Measurement results of SSB in cell 1;

[0187] Measurement results for cell 2;

[0188] Measurement results of SSB in cell 2;

[0189] The measurement result for cell 3; or

[0190] Measurement results for SSB in cell 3.

[0191] For example:

[0192] The terminal device information includes identification information of the terminal device. Network device 120 determines the corresponding terminal device based on the identification information of the terminal device and can determine that there is no data transmission between the terminal device and network device 120. Furthermore, network device 120 determines that a certain cell in network device 110 has a CCO problem and, based on this determination, can filter cells requiring configuration adjustment from one or more cells under the jurisdiction of network device 120. For example, if cell 2 is determined to be a cell requiring configuration adjustment, coverage of cell 2 can be enhanced. In this way, network device 110 can resolve the CCO problem in cell 1 without having to adjust the configuration of cell 1, which helps reduce the power consumption of network device 110 and thus brings greater benefits.

[0193] The identification information of the terminal device may include the identification of the terminal device, for example, the next generation radio access network node user equipment Xn application protocol ID (NG-RAN node UE XnAP ID) or other identification, and may also include other information used to distinguish the terminal device, which is not limited.

[0194] For example:

[0195] The information of the terminal device includes the measurement result of cell 1. The network device 120 can determine whether the cell 1 has a CCO problem based on the measurement result of cell 1.

[0196] The measurement result of cell 1 may include one or more of: RSRP of cell 1, reference signal received quality (RSRQ) of cell 1, and signal to interference plus noise ratio (SINR) of cell 1. The measurement result of cell 1 may also include identification information of cell 1.

[0197] For example:

[0198] The information of the terminal device includes the measurement result of the SSB in cell 1. The network device 120 can determine whether there is a CCO problem in cell 1 based on the measurement result of the SSB in cell 1.

[0199] The SSBs in cell 1 may include all SSBs in cell 1, or may include only SSBs in cell 1 that are related to the CCO problem (eg, SSBs whose RSRP is less than a threshold).

[0200] The measurement result of the SSB in cell 1 may include an SSB index (SSB index) and at least one of the following: one or more of RSRP, RSRQ or SINR of the SSB.

[0201] For example:

[0202] The information of the terminal device includes the measurement result of cell 2. The network device 120 can determine whether the configuration of cell 2 needs to be adjusted based on the measurement result of cell 2, so as to solve the CCO problem of cell 1.

[0203] The measurement result of cell 2 includes identification information of cell 2 and at least one of the following: one or more of RSRP, RSRQ or SINR of cell 2.

[0204] For example:

[0205] The information of the terminal device includes the measurement results of SSB in cell 2. The network device 120 can determine whether the configuration of cell 2 needs to be adjusted based on the measurement results of SSB in cell 2, which can help solve the CCO problem of cell 1.

[0206] The SSBs in cell 2 may include all SSBs in cell 2, or may include only SSBs related to the CCO problem (eg, the SSBs that cause the strongest interference to the terminal device in cell 1).

[0207] The measurement result of the SSB in cell 2 may include identification information of cell 2, an SSB index, and at least one of the following: one or more of RSRP, RSRQ, or SINR of the SSB.

[0208] For example:

[0209] The information of the terminal device includes the measurement result of cell 3. The network device 120 can determine whether cell 1 has a CCO problem based on the measurement result of cell 3 (for example, if the difference between the measurement result of cell 3 and the measurement result of cell 1 is less than a threshold, it means that the user in cell 1 is easily affected by cell 3; for example, if the measurement result of cell 3 is less than a threshold, the network device 120 can determine that cell 1 may have a CCO problem), and then determine whether the configuration of cell 2 needs to be adjusted, which can help solve the CCO problem in cell 1.

[0210] The measurement result of cell 3 includes identification information of cell 3 and at least one of the following: one or more of RSRP, RSRQ, and SINR of cell 3.

[0211] For example:

[0212] When the information of the terminal device includes the measurement result of the SSB in cell 3, the network device 120 can determine whether there is a CCO problem in cell 1 based on the measurement result of cell 3 (for example, if the difference between the measurement result of cell 3 and the measurement result of cell 1 is less than a threshold, it means that the user in cell 1 is easily affected by cell 3), and then determine whether the configuration of cell 2 needs to be adjusted, which can help solve the CCO problem of cell 1.

[0213] The SSBs in cell 3 may include all SSBs in cell 3, or may include only SSBs related to the CCO problem (for example, the SSBs that have the strongest interference to the terminal device in cell 1).

[0214] The measurement result of the SSB in cell 3 may include identification information of cell 3, an SSB index, and at least one of the following: one or more of RSRP, RSRQ, and SINR of the SSB.

[0215] It should be noted that the network device 110 may also send information about measurement results of more neighboring cells of the cell 1 to the network device 120. The network device 120 may determine whether the cell 1 has a CCO problem based on the measurement results of more neighboring cells of the cell 1.

[0216] The network device 120 can determine that there is a CCO problem in cell 1 based on one or more of the above-mentioned items, and then determine to adjust the configuration of cell 2. In this way, the CCO problem of cell 1 can be solved, thereby bringing higher gains to the network device 110 in solving the CCO problem of cell 1, for example, saving the power consumption of the network device 110.

[0217] Optionally, the terminal device information may also include location information of the terminal device. For example, time advance (TA), angle of arrival (AOA), and SSB index of the serving terminal device. In this way, network device 120 can determine the approximate location of the terminal device and further determine whether cell 1 has a CCO problem.

[0218] In summary, one or more of the information 1 listed above can be used by the network device 120 to determine the cell that needs to be configured and adjusted, to help solve the CCO problem of cell 1, which is beneficial for the network device 110 to solve the CCO problem of cell 1 and bring greater gains, for example, it can reduce the power consumption of the network device 110.

[0219] In one possible implementation, the information 1 may further include at least one of the following:

[0220] Identification information of cell 2, or at least one first configuration information, where the first configuration information indicates that configuration adjustment of cell 2 is to be performed.

[0221] In one example, information 1 includes identification information of cell 2. Network device 120 can determine cell 2 based on the identification information of cell 2 and adjust the configuration of cell 2. For example, embodiments of the present application can support protocol agreement or configure network device 110 to send identification information of a certain cell to network device 120, which is used to indicate that the cell is a cell that requires configuration adjustment. In this way, the CCO problem of cell 1 can be solved, thereby bringing greater benefits to network device 110 in solving the CCO problem of cell 1, for example, the power consumption of network device 110 can be reduced.

[0222] In one example, information 1 includes at least one first configuration information, and the network device 120 can adjust the configuration of cell 2 according to any first configuration information. In this way, the CCO problem of cell 1 can be solved, thereby bringing greater gains to the network device 110 in solving the CCO problem of cell 1, for example, the power consumption of the network device 110 can be reduced.

[0223] The network device 120 can adjust the configuration of cell 2 according to one or two of the above items, so as to solve the CCO problem of cell 1, thereby bringing higher gains to the network device 110 in solving the CCO problem of cell 1, for example, saving the power consumption of the network device 110.

[0224] In one possible implementation, the first configuration information may include at least one of the following:

[0225] Adjusted cell coverage state parameters of cell 2;

[0226] Adjusted SSB coverage state parameters of cell 2;

[0227] The adjusted mobility parameters of cell 2 and identification information of the neighboring cells of cell 2.

[0228] The network device 120 adjusts the configuration of cell 2 according to one or more of the above items, thereby solving the CCO problem of cell 1, thereby bringing higher gains to the network device 110 in solving the CCO problem of cell 1, for example, saving the power consumption of the network device 110.

[0229] When the first configuration information includes the adjusted cell coverage status parameter of cell 2, the network device 120 adjusts the cell coverage status of cell 2 according to the parameter. The value of the cell coverage status can be an integer, and the cell coverage configuration corresponding to the integer is pre-determined by the network management and issued to each network device.

[0230] When the first configuration information includes the adjusted SSB coverage status parameter of cell 2, the network device 120 adjusts the SSB coverage status of cell 2 according to the parameter. The value of the SSB coverage status can be an integer, and the SSB coverage configuration corresponding to the integer is pre-determined by the network management and issued to each network device.

[0231] Optionally, the adjusted SSB coverage state parameter of cell 2 may further include an SSB index, which may be used to indicate an SSB for which coverage state adjustment is required.

[0232] When the first configuration information includes the adjusted mobility parameters of cell 2, the network device 120 adjusts the mobility parameters of cell 2 according to the parameters. The mobility parameters may include a handover trigger value (Handover Trigger) or a change amount of the handover trigger value.

[0233] The mobility parameter may be used to indicate a condition for a terminal device located in cell 2 to switch from cell 2 to a neighboring cell of cell 2. For example, if the mobility parameter is 20 dBm, when the terminal device located in cell 2 determines that the difference between the RSRP of cell 2 and the RSRP of a neighboring cell of cell 2 is less than 20 dBm, the terminal device located in cell 2 may switch from cell 2 to the neighboring cell.

[0234] It should be noted that information 1 includes identification information of cell 2 and at least one first configuration information, and the first configuration information may not carry identification information of cell 2. Information 1 only includes at least one first configuration information, and the first configuration information may include identification information of cell 2. Information 1 does not carry identification information of cell 2, but carries identification information of cell 1. The first configuration information can be applicable to any cell adjacent to cell 1 and under the jurisdiction of network device 120, without limitation.

[0235] In one possible implementation, the information 1 may further include at least one of the following:

[0236] at least one second configuration information, where the second configuration information indicates a configuration adjustment for a cell*;

[0237] At least one second configuration information and an evaluation index, where the evaluation index indicates an index used when evaluating the at least one second configuration information.

[0238] Cell* can be used to indicate cell 1, or a neighboring cell of cell 1, such as cell 3. In other words, by adjusting the configuration of cell*, the CCO problem of cell 1 can be solved. For ease of description, the following description uses cell* as an example.

[0239] In one example, information 1 includes at least one second configuration information, and network device 120 determines or selects one or more second configuration information from the at least one second configuration information. In this way, network device 110 can determine appropriate second configuration information based on the recommendation of network device 120. A detailed description is provided below.

[0240] In one example, information 1 includes an evaluation indicator and at least one second configuration information, and the network device 120 evaluates the at least one second configuration information according to the evaluation indicator.

[0241] Optionally, the evaluation indicator may also be understood as a feedback indicator, which indicates an indicator used when providing feedback or evaluating the at least one second configuration information.

[0242] Optionally, the evaluation indicators may also be expressed using other terms, which are not limited thereto.

[0243] Optionally, the evaluation indicator can also be understood as an indicator for requesting feedback, wherein the evaluation indicator is used to indicate which indicators to use when requesting the network device 120 to evaluate the second configuration information, or to indicate which indicators to feedback after requesting the network device 120 evaluates the second configuration information.

[0244] The network device 120 can evaluate the second configuration information based on one or more of the above-mentioned items, which is helpful in helping the network device 110 determine a suitable configuration adjustment plan. The suitable configuration adjustment plan can enable the network device 110 to avoid making major adjustments to the configuration of cell 1, etc., which can bring higher gains to the network device 110 in solving the CCO problem of cell 1.

[0245] In one possible implementation, the evaluation indicators may include at least one of the following:

[0246] at least one third configuration information, where the third configuration information is used to adjust the configuration of cell 2, and the at least one third configuration information corresponds one-to-one with the at least one second configuration information;

[0247] at least one prediction information, the at least one prediction information corresponding to the at least one second configuration information, the prediction information being used to predict device performance under the corresponding second configuration information;

[0248] The at least one second configuration information is configuration information acceptable to the network device 120 .

[0249] Optionally, the third configuration information mentioned above may indicate configuration adjustments that may be taken by cell 2 under the corresponding second configuration information.

[0250] Optionally, the configuration information acceptable to the network device 120 may also be understood as the configuration information recommended by the network device 120 .

[0251] Through one or more of the above, the network device 120 reasonably evaluates each second configuration information, thereby helping the network device 110 determine an appropriate configuration adjustment solution.

[0252] Exemplary:

[0253] The evaluation indicator includes at least one third configuration information, which indicates that the network device 120 needs to determine a configuration adjustment solution for the cell 2 according to each second configuration information.

[0254] For example, when network device 110 adjusts the configuration of cell * based on the second configuration information, network device 120 also needs to make corresponding configuration adjustments to cell 2. For each piece of second configuration information, network device 120 needs to determine the corresponding third configuration information, which is used to adjust the configuration of cell 2. The third configuration information can be understood as configuration information that network device 120 may adopt.

[0255] For the description of the third configuration information, please refer to the description of the first configuration information above and will not be repeated here.

[0256] Exemplary:

[0257] The evaluation indicator includes at least one prediction information, which may indicate that the network device 120 needs to predict the performance of the terminal device after the cell* is configured and adjusted using the second configuration information.

[0258] For example, the network device 110 uses the second configuration information to adjust the configuration of the cell *, then the performance of the terminal devices in the cell * will change to a certain extent, and the network device 120 needs to predict the performance change of the terminal devices in the cell *.

[0259] In one possible implementation, the prediction information includes at least one of the following:

[0260] Prediction of measurement results for cell*.

[0261] Prediction of measurement results for neighboring cells of cell*.

[0262] Prediction of the measurement results of SSB for cell*.

[0263] Prediction of the SSB measurement results in the neighboring cells of cell*.

[0264] Indication information 1 (for example, the first indication information) indicates whether the cell* has a CCO problem.

[0265] Through one or more of the above, the network device 120 can reasonably evaluate each second configuration information, thereby helping the network device 110 to determine an appropriate configuration adjustment solution.

[0266] Exemplary:

[0267] After the cell* uses a certain second configuration information to perform configuration adjustment, what will be the measurement result obtained by the terminal equipment in the cell* by re-measuring the cell*?

[0268] The prediction of the measurement result of cell* includes at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0269] After the cell* uses a certain second configuration information to perform configuration adjustment, what will be the measurement result obtained by the terminal equipment in the cell* by re-measuring the neighboring cells of the cell*?

[0270] The neighboring cells of cell* may include all neighboring cells of cell*, or may include only neighboring cells related to the CCO problem (eg, neighboring cells that have the strongest interference to the terminal device in cell*).

[0271] The prediction of the measurement result of the neighboring cell of cell* includes identification information of the neighboring cell of cell* and at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0272] After the cell* uses a certain second configuration information to adjust the configuration, what will be the measurement result obtained by the terminal equipment in the cell* when re-measuring the SSB in the cell*?

[0273] The SSBs in the cell* may include all SSBs in the cell*, or may include only SSBs in the cell* that are related to the CCO problem (eg, SSBs whose RSRP is less than a predetermined threshold).

[0274] The prediction of the measurement result of the SSB in cell* includes the SSB index and at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0275] After the cell * uses a certain second configuration information to adjust the configuration, what will be the measurement result obtained by the terminal equipment in the cell * by re-measuring the SSB in the neighboring area of ​​the cell *?

[0276] The SSBs in the neighboring cells of cell* may include all SSBs in all neighboring cells of cell*, or may only include SSBs related to the CCO problem (e.g., the SSBs that cause the strongest interference to the terminal devices in cell*).

[0277] The prediction of the measurement result of the SSB in the neighboring cell of cell* includes identification information of the neighboring cell of cell*, an SSB index, and at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0278] After cell * is configured and adjusted using the second configuration information, network device 120 needs to predict whether CCO problem will continue to occur or exist in cell 1 or cell *. Network device 120 may indicate the prediction of whether CCO problem will exist in cell * or cell 1 through indication information 1.

[0279] For example, the indication information 1 may be 1 bit: if the value is "1", it indicates that the prediction result is "yes", and if the value is "0", it indicates that the prediction result is "no".

[0280] The network device 120 needs to predict each piece of second configuration information to obtain corresponding prediction information.

[0281] The prediction information may be for one terminal device or for multiple terminal devices, and there is no limitation on this.

[0282] The neighboring cells of cell* may include all neighboring cells or only the neighboring cells that are relevant to the CCO problem (for example, the neighboring cells that have the strongest interference to the terminal devices in cell*).

[0283] Exemplary:

[0284] When the evaluation indicator includes configuration information acceptable to the network device 120 in at least one second configuration information, it may mean that after the network device 120 evaluates each second configuration information (for example, predicts or determines the corresponding third configuration information), it is necessary to determine the second configuration information acceptable or recommended by the network device 120 in at least one second configuration information.

[0285] The evaluation indicator may include several bits, each bit corresponding to an indicator. For example, the evaluation indicator includes two bits, the first bit corresponding to the "third configuration information" and the second bit corresponding to the "prediction information." When each bit is set to "1," it indicates that the network device 120 is requested to provide feedback on the corresponding indicator, and when the bit is set to "0," it indicates that the network device 120 is not requested to provide feedback on the corresponding indicator.

[0286] Optionally, the evaluation indicator may also be used to request an evaluation of acceptable second configuration information or to request feedback of recommended second configuration information. For example, the evaluation indicator may be used to instruct network device 120 to evaluate or provide feedback on whether to accept at least one second configuration information that network device 110 may adopt, or to accept part of the second configuration information among the at least one second configuration information that network device 110 may adopt, or to recommend to network device 110 a second configuration information among the at least one second configuration information that network device 110 may adopt.

[0287] In one possible implementation, the second configuration information may include at least one of the following:

[0288] identification information of the cell*, and the adjusted cell coverage status parameters of the cell*;

[0289] Identification information of cell*, and adjusted SSB coverage status parameters of cell*;

[0290] Identification information of the cell*, the adjusted mobility parameters of the cell*, and identification information of the neighboring cells of the cell*.

[0291] The network device 120 may determine the configuration adjustments that the network device 110 may make to the cell 1, thereby helping the network device 110 to determine an appropriate configuration adjustment.

[0292] When the second configuration information includes the identification information of the cell* and the adjusted cell coverage status parameter of the cell*, the network device 120 determines that the network device 110 will adjust the cell coverage configuration of the cell*.

[0293] When the second configuration information includes the identification information of the cell* and the adjusted SSB coverage status parameter of the cell*, the network device 120 determines that the network device 110 will adjust the SSB coverage configuration of the cell*.

[0294] When the second configuration information includes the identification information of cell*, the adjusted mobility parameter of cell*, and the identification information of the neighboring cells of cell*, network device 120 determines that network device 110 will adjust the mobility parameter configuration of cell*.

[0295] For the description of the cell coverage status parameters, SSB coverage status parameters and mobility parameters of cell *, please refer to the above description of cell 2 and will not be repeated here.

[0296] In summary, the network device 120 can obtain or determine the information about the CCO problem of the cell 1 through the information 1 .

[0297] S402 : Network device 120 sends information 2 to network device 110 .

[0298] Accordingly, the network device 110 receives information 2. The information 2 indicates a handling strategy for the CCO problem of the cell 1.

[0299] Information 2 is sent by network device 120 to network device 110 in response to information 1.

[0300] The sending of information 2 in response to information 1 may include: network device 120 determining second information 2 based on first information 1, or network device 120 referring to information 1 when determining information 2. In this manner, after receiving information 1, network device 120 sends information 2 to network device 110, thereby helping network device 110 determine a strategy for handling the CCO problem in cell 1.

[0301] Exemplarily, after the network device 120 obtains or determines information about the CCO problem of cell 1 according to information 1, the network device 120 determines a strategy for handling the CCO problem of cell 1. For example, the network device 120 adjusts the configuration of cell 2, which can help solve the CCO problem of cell 1. The network device 110 does not need to solve the CCO problem of cell 1, thereby reducing the power consumption of the network device 110. For example, the network device 120 helps the network device 110 determine a suitable configuration adjustment solution for cell 1, so that the network device 110 can select a configuration adjustment solution with lower power consumption to adjust the configuration of cell 1. This can not only solve the CCO problem of cell 1, but also reduce the power consumption of the network device 110.

[0302] In summary, after determining that a CCO problem exists in cell 1, network device 110 may send information about the CCO problem in cell 1 to network device 120. Network device 120 may, based on the information, indicate to network device 110 a strategy for handling the CCO problem in cell 1, and network device 110 may handle the CCO problem in cell 1 according to the strategy. For example, network device 110 may determine a suitable configuration adjustment solution for cell 1, where the suitable configuration adjustment solution may eliminate the need for the first network device to make significant adjustments to the configuration of the first cell, or network device 110 may determine that the CCO problem in cell 1 does not need to be resolved.

[0303] Therefore, the above solution can bring greater benefits to the network device 110 in solving the CCO problem of cell 1. For example, the network device 120 solves the CCO problem of cell 1, and the network device 110 does not need to solve the CCO problem of cell 1; for example, the network device 120 helps the network device 110 determine a suitable configuration adjustment solution, and the network device 110 can adjust the configuration of cell 1 in a manner with lower power consumption to solve the CCO problem of cell 1.

[0304] The method shown in FIG. 4 is further described below in conjunction with FIG. 5 to FIG. 7 .

[0305] FIG5 is a schematic diagram of an interaction flow of another communication method according to an embodiment of the present application. As shown in FIG5 , the method includes:

[0306] Optionally, in S501 , the network device 110 determines that a CCO problem exists in cell 1 .

[0307] Exemplarily, the terminal device 130 sends the measurement result of the cell 1 to the network device 110 , and the network device 110 determines that the CCO problem exists in the cell 1 according to the measurement result of the cell 1 .

[0308] Exemplarily, the terminal device 130 sends the measurement results of cell 1 and cell 2 to the network device 110. The network device 110 may determine that a CCO problem exists in cell 1 based on the difference between the measurement results of cell 1 and cell 2.

[0309] In summary, for the description of the network device 110 determining that the CCO problem exists in cell 1, reference can be made to the description of the aforementioned four conditions, which will not be elaborated herein.

[0310] S502 : The network device 110 sends information 1 to the network device 120 .

[0311] Accordingly, the network device 120 receives information 1, wherein the information 1 indicates the CCO problem of the cell 1.

[0312] After network device 110 determines that a CCO problem exists in cell 1, network device 110 determines whether to adjust the configuration of cell 1. For example, if the coverage of cell 1 is large and there is no need to expand the coverage of cell 1, network device 110 may determine that network device 120 adjusts the configuration of the cells under its jurisdiction to resolve the CCO problem in cell 1.

[0313] The above-mentioned information 1 may include:

[0314] identification information of cell 1;

[0315] Type of CCO problem in cell 1;

[0316] Information of the terminal device, which belongs to cell 1.

[0317] For the description of the above information, please refer to the previous description and will not be repeated here.

[0318] S503 : The network device 120 adjusts the configuration of cell 2 .

[0319] After the network device 120 determines that the CCO problem exists in cell 1 according to information 1, a possible implementation is that the network device 120 screens cells adjacent to cell 1 in one or more cells under the jurisdiction of the network device 120 to determine the cell requiring configuration adjustment.

[0320] For example, the network device 120 determines that cell 2 is adjacent to cell 1 and the coverage range of cell 2 is smaller. The network device 120 can adjust the configuration of cell 2, for example, adjust one or more of the cell coverage status parameters, SSB coverage status parameters, and mobility parameters of cell 2, thereby solving the CCO problem of cell 1.

[0321] Optionally, the network device 120 may further perform configuration adjustment on one or more cells under the jurisdiction of the network device 120 , without limitation.

[0322] Through the above solution, when network device 110 determines that there is a CCO problem in cell 1, it can send information about the CCO problem of cell 1 to network device 120. Network device 120 determines the cell that needs to be configured and adjusted among one or more cells under the jurisdiction of network device 120 based on the information, thereby helping to solve the CCO problem in cell 1.

[0323] Compared with the solution in which the network device 110 directly adjusts the configuration of cell 1 after determining that there is a CCO problem in cell 1, the above solution can bring greater gains to the network device 110 in solving the CCO problem of cell 1. For example, the network device 110 does not need to solve the CCO problem of cell 1, and the network device 120 solves the CCO problem of cell 1, which is conducive to reducing the power consumption of the network device 110.

[0324] Since there is no terminal device in cell 2, network device 120 cannot determine whether there is a CCO problem in cell 2. Through the above solution, network device 120 can adjust the configuration of cell 2, which helps to reduce the probability of CCO problem in cell 2 after the configuration adjustment.

[0325] Optionally, the method may further include:

[0326] S504a: The network device 120 sends information 2 to the network device 110. The information 2 includes the adjusted configuration information of the cell 2.

[0327] Accordingly, the network device 110 receives the information 2 .

[0328] For example, the adjusted configuration information of cell 2 may include at least one of the following:

[0329] Adjusted cell coverage status parameters of cell 2;

[0330] Adjusted SSB coverage status parameters in cell 2;

[0331] The adjusted mobility parameters of cell 2 and identification information of the neighboring cells of cell 2.

[0332] The network device 110 can determine that the network device 120 has adjusted the configuration of cell 2 based on one or more of the above-mentioned items, and determine that the CCO problem of cell 1 can be solved after the configuration of cell 2 is adjusted. In this way, the network device 110 can determine that the network device 110 does not need to solve the CCO problem of cell 1 based on information 2, which can save the power consumption of the network device 110, thereby bringing higher gains for the network device 110 to solve the CCO problem of cell 1.

[0333] Specifically, the network device 110 may determine whether the CCO problem still exists in cell 1 based on the adjusted configuration information of cell 2. When the network device 110 determines that the CCO problem still exists in cell 1, the network device 110 may send an indication message to the network device 120, where the indication message is used to indicate that the CCO problem still exists in cell 1. The network device 120 may optimize the configuration of cell 2 based on the indication message to resolve the CCO problem in cell 1.

[0334] Optionally, the method may further include:

[0335] S504b: The network device 120 sends information 2 to the network device 110 , where the information 2 includes a reason value indicating that the configuration adjustment of the cell 2 has failed.

[0336] Accordingly, the network device 110 receives the information 2 .

[0337] Optionally, information 2 may indicate that the configuration adjustment of cell 2 has failed. In one possible implementation, information 2 includes a cause value, which is used to indicate that the configuration adjustment of cell 2 has failed. In this way, network device 110 can determine, based on information 2, that network device 120 has failed to adjust the configuration of cell 2, and can therefore determine that network device 110 needs to resolve the CCO problem of cell 1 on its own.

[0338] When the network device 120 determines that the configuration adjustment of cell 2 cannot be performed, the network device 120 can send a reason value indicating the failure of the configuration adjustment of cell 2 to the network device 110. The network device 110 can determine that the network device 120 cannot adjust the configuration of cell 2 based on the reason value. The network device 110 can then adjust the configuration of cell 1 or cell 3, thereby solving the CCO problem of cell 1.

[0339] In a possible implementation, the above-mentioned reason value may include: no suitable configuration, or configuration adjustment is not supported.

[0340] Exemplary:

[0341] The reason value is "configuration adjustment not supported", which means that the network device 120 uses a fixed cell configuration and cannot be adjusted. If the network device 110 subsequently finds that the cell has a CCO problem, it will no longer send information 1 to the network device 120.

[0342] Exemplary:

[0343] The reason value is "No Suitable Configuration", which means: the network device 120 supports cell configuration adjustment, but no suitable configuration was found at this time. If the network device 110 finds that the cell has a CCO problem later, it can still send information 1 to the network device 120.

[0344] The solution shown in FIG5 is described by taking the example of the network device 120 adjusting the configuration of cell 2 to solve the CCO problem of cell 1. The present application also supports solving the CCO problem of cell 1 by other means, as shown in FIG6.

[0345] FIG6 is a schematic diagram of an interaction flow of another communication method according to an embodiment of the present application. As shown in FIG6 , the method includes:

[0346] Optionally, in S601 , the network device 110 determines that a CCO problem exists in cell 1 .

[0347] For the description of S601 , refer to the description of S501 .

[0348] S602 : Network device 110 sends information 1 to network device 120 , where information 1 indicates the CCO problem of cell 1 .

[0349] Accordingly, the network device 120 receives the information 1 .

[0352] The description of the above information can be found in the previous article and will not be repeated here.

[0353] An example description of information 1 can be found in Table 1. The content shown in Table 1 is only an example and is not intended to be a final limitation.

[0362] Line 20 represents configuration information 2 (such as the second second configuration information);

[0363] The content described in line 21 is of the same type as the content described in lines 6 to 19;

[0364] Line 22 indicates the evaluation indicators. Please refer to the description of the evaluation indicators above.

[0365] Line 23 indicates the second configuration information that is acceptable to the request evaluation, which can be found in the previous description.

[0366] The contents described in Table 1 are only examples. In specific applications, some of the contents in Table 1 can be used for indication without limitation.

[0367] S603: The network device 120 evaluates at least one second configuration information included in the information 1.

[0368] In one example, the network device 120 may evaluate the at least one second configuration information according to the evaluation indicator.

[0369] For a detailed description, please refer to the description of the evaluation indicators above, which will not be repeated here.

[0370] S604a: The network device 120 sends information 2 to the network device 110. The information 2 includes the evaluation result.

[0371] Accordingly, the network device 110 receives the information 2 .

[0372] Information 2 may also include at least one of the following:

[0373] Indication information 2 is used to indicate whether to accept the at least one second configuration information. Indication information 2 can be one bit: a value of "1" indicates acceptance of the at least one second configuration information that network device 110 may adopt; a value of "0" indicates rejection of the at least one second configuration information that network device 110 may adopt.

[0374] Indication information 3 is used to indicate acceptable second configuration information or recommended second configuration information in at least one second configuration information. Indication information 3 can be used to instruct network device 120 to accept or recommend second configuration information in the second configuration information that network device 110 may adopt.

[0375] At least one evaluation result, wherein the at least one evaluation result corresponds to the at least one second configuration information, wherein the evaluation result is determined based on the aforementioned evaluation index, in other words, the evaluation result corresponds to the evaluation index.

[0376] The network device 110 can determine appropriate second configuration information in at least one second configuration information based on one or more of the above-mentioned items, and adjust the configuration of the cell based on the appropriate second configuration information, thereby solving the CCO problem of cell 1, and at the same time bringing higher gains, for example, lower power consumption of the network device 110, etc.

[0377] Each of the above assessment results may include at least one of the following:

[0378] Third configuration information;

[0379] Predictive information.

[0380] For the description of the third configuration information and prediction information, please refer to the previous text and will not be repeated here.

[0381] Optionally, S604b, the network device 120 sends information 2 to the network device 110, where the information 2 includes a reason value indicating a failure in the evaluation.

[0382] Accordingly, the network device 110 receives the information 2 .

[0383] Optionally, the aforementioned information 2 may indicate an evaluation failure. In one possible implementation, information 2 includes a reason value indicating an evaluation failure. Thus, network device 110 may determine, based on information 2, that network device 120 has failed to evaluate the second configuration information, and may thereby determine that network device 110 needs to independently determine appropriate second configuration information.

[0384] The network device 110 may determine, based on the above-mentioned information 2, that the network device 120 is unable to evaluate the second configuration information, and the network device 110 may determine appropriate second configuration information on its own.

[0385] When network device 120 fails to evaluate at least one second configuration information, network device 120 may send a reason value indicating evaluation failure to network device 110, and network device 110 may determine the reason for evaluation failure of network device 120 according to the reason value.

[0386] In a possible implementation, the above-mentioned reason value may include: no evaluation result is obtained or evaluation of at least one second configuration is not supported, etc.

[0387] Exemplary:

[0388] When the reason value is "no evaluation result obtained," it may indicate that the network device 120 has the evaluation function, but has not obtained a suitable evaluation result this time. If the network device 110 subsequently discovers a CCO problem, it may still send information 1 to the network device 120.

[0389] Exemplary:

[0390] When the reason value indicates that the evaluation of at least one second configuration information is not supported, it may indicate that the network device 120 does not have the evaluation function. When the network device 110 subsequently discovers the CCO problem, it will no longer send information 1 to the network device 120.

[0391] An example description of information 2 can be found in Table 2. The content shown in Table 2 is only an example and is not intended to be a final limitation.

[0392] Table 2

[0393] As shown in Table 2:

[0394] Line 1 indicates that network device 120 accepts the second configuration information that network device 110 may adopt:

[0395] The second line indicates that the recommended second configuration information is configuration information 1;

[0396] Line 3 shows the evaluation result list:

[0397] The fourth line shows the evaluation result of configuration information 1:

[0398] The fifth row indicates that corresponding to the configuration information 1, the third configuration information that the network device 120 may adopt is the configuration information 3;

[0400] The 7th line indicates the identity of cell M;

[0401] The eighth row shows the coverage status of cell M, which is the coverage status of the cell after configuration adjustment;

[0402] The 9th row represents cell N, which belongs to network device 120;

[0403] Line 10 indicates the identity of cell N;

[0404] Line 11 shows the coverage adjustment list of SSB in cell N;

[0405] Line 12 indicates the index of SSB1;

[0406] Line 13 indicates the coverage status of SSB1;

[0407] Line 14 indicates that corresponding to configuration information 1, another third configuration information that the network device 120 may adopt is configuration information 4;

[0408] Line 15 indicates the specific content of configuration information 4, which can be found in lines 6 to 13.

[0409] Line 16 represents the prediction information;

[0410] Line 17 represents the performance prediction information of terminal device 1, which belongs to cell 1;

[0411] The 18th row represents the prediction information of the performance of terminal device 2, which belongs to cell 1.

[0412] Network device 120 may indicate the evaluation result to network device 110 in the form of Table 2.

[0413] The contents described in Table 2 are only examples. In specific applications, some of the contents in Table 2 may be used for indication without limitation.

[0414] S605: The network device 110 determines the adjusted configuration information of the cell*.

[0415] When information 2 includes a cause value, network device 110 selects a second configuration information from the at least one second configuration information and adjusts the configuration of cell * based on the second configuration information. When information 2 includes at least one evaluation result, network device 110 selects an appropriate second configuration information from the at least one second configuration information based on the at least one evaluation result and adjusts the configuration of cell * based on the second configuration information.

[0416] The description of the adjusted configuration information of cell* can refer to the aforementioned description of the adjusted configuration information of cell 2, which is not repeated here.

[0417] Through the above scheme, the network device 110 can obtain the evaluation result of the network device 120 on the second configuration information, and can determine a suitable configuration adjustment scheme based on the evaluation result, so that the network device 110 can adjust the configuration of the cell* in a lower power consumption manner, which is conducive to reducing the power consumption of the network device 110.

[0418] In addition, the above solution can also effectively avoid negative impacts on the network device 120 .

[0419] S606 : The network device 110 sends information 3 to the network device 120 , where the information 3 includes the adjusted configuration information of the cell*.

[0420] Accordingly, the network device 120 receives information 3 and obtains the adjusted configuration information of the cell* based on information 3, and can adjust the configuration of one or more cells under the jurisdiction of the network device 120 accordingly based on the adjusted configuration information of the cell*.

[0421] It should be noted that some steps in the solution described in Figure 6 may be optional, for example, S604b is optional. Therefore, the above description is only understood as an example and not as a final limitation.

Specifically, the DU is responsible for protocol layers with high real-time requirements, while the CU is responsible for protocol layers with low real-time requirements. The DU should be deployed as close to the antenna as possible; the CU can be located further away from the antenna, and multiple CUs can be deployed centrally in the cloud to achieve resource sharing.
