Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and more specifically, to a communication method, device, and system. Background Art

[0002] Coverage and capacity optimization (CCO) is an important network self-optimization function, which can be used to detect and solve one or both of the coverage problem and capacity problem of a cell.

[0003] When a CCO problem is detected in a cell, the network device to which the cell belongs can solve 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 synchronization signal physical broadcast channel block (also referred to as synchronization signal block) (synchronization signal / physical broadcast channel block, SSB) of the cell. 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.

[0004] 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

[0005] The present application provides a communication method, apparatus and system, which can support a network device that detects a CCO problem and solves the CCO problem to bring higher gain.

[0006] In a first aspect, a communication method is provided, the method 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; in response to the first information, sending second information to the first network device, the second information indicating a handling strategy for the CCO problem of the first cell.

[0007] The above method can be applied to the second network device. It can be understood that the execution subject 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, logical module or software that can realize all or part of the functions of the second network device, without limitation. For ease of description, the following description is taken as an example of the second network device.

[0008] The sending of the second information in response to the first information may include: the second network device determines the second information based on the first information, or the second network device refers to the first information when determining the second information. In this way, 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 handling strategy for the CCO problem of the first cell.

[0009] In a possible implementation, the second information indicates a processing strategy for the CCO problem of the first cell, which may include: after receiving the second information, the first network device may determine a processing strategy for the CCO problem of the first cell, for example, the first network device determines a suitable configuration adjustment scheme for the first cell (the suitable configuration adjustment scheme may make it unnecessary for the first network device to make a large adjustment to the configuration of the first cell, etc.), or the first network device determines that it is unnecessary to solve the CCO problem of the first cell, etc. In this way, the above scheme may bring higher gain to the first network device in solving the CCO problem.

[0010] In the above scheme, after the first network device determines that there is a CCO problem in the first cell, it can send information about the CCO problem of the first cell to the second network device, and the second network device can indicate to the first network device a processing strategy for the CCO problem of the first cell based on the information, and the first network device processes the CCO problem of the first cell according to the processing strategy. For example, the first network device determines a suitable configuration adjustment scheme for the first cell (the suitable configuration adjustment scheme can make the first network device not need to make a large adjustment to the configuration of the first cell, etc.), or the first network device determines that there is no need to solve the CCO problem of the first cell, etc.

[0011] The above solution can bring greater gains 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 plan, 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.

[0012] In the first aspect, the method may further include: receiving third information, the third information including configuration information of the adjusted cell.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] The above method can be applied to the first network device. It can be understood that the execution subject 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, logical module or software that can realize all or part of the functions of the first network device, without limitation. For ease of description, the following description takes the first network device as an example.

[0017] In the above scheme, after the first network device determines that there is a CCO problem in the first cell, it can send information about the CCO problem of the first cell to the second network device, and the second network device can indicate to the first network device a processing strategy for the CCO problem of the first cell based on the information, and the first network device processes the CCO problem of the first cell according to the processing strategy. For example, the first network device determines a suitable configuration adjustment scheme for the first cell (the suitable configuration adjustment scheme can make the first network device not need to make a large adjustment to the configuration of the first cell, etc.), or the first network device determines that there is no need to solve the CCO problem of the first cell, etc.

[0018] The above solution can bring greater gains 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 plan, 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.

[0019] In 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.

[0020] 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 the first cell has a CCO problem. For example, an embodiment of the present application can support a protocol agreement or configuration that 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 the cell has a CCO problem.

[0021] In one example, when the first information includes the type of the CCO problem of the first cell, the second network device determines that a certain cell in the first network device has a CCO problem, and adjusts the configuration of one or more cells adjacent to the first cell under the jurisdiction of the second network device. In this way, the first network device can solve the CCO problem in the first cell without adjusting the configuration of the first cell, which is conducive to reducing the power consumption of the first network device, thereby bringing greater gains.

[0022] In one example, when the first information includes information of a terminal device, the information of the terminal device can be used to indicate that a certain cell in the first network device has a CCO problem. For example, an embodiment of the present application can support a protocol agreement or configuration that when the first network device sends information of a terminal device to the second network device, the information of the terminal device can be used to indicate that a certain cell in the first network device has a CCO problem.

[0023] Through one or more of the above, the second network device can obtain or determine the information of the CCO problem of the first cell.

[0024] 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: 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.

[0025] The above-mentioned second cell is a neighboring cell of the first cell.

[0026] The second network device can adjust the configuration of the second cell according to one or two of the above-mentioned items, so as to solve the CCO problem of the first cell, thereby bringing higher gain 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.

[0027] 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.

[0028] 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.

[0029] The second network device can determine that there is a CCO problem in the first cell 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 gain 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.

[0030] 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.

[0031] The second network device adjusts the configuration of the second cell according to one or more of the above-mentioned items, so as to solve the CCO problem of the first cell, thereby bringing higher gain 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.

[0032] In combination with the scheme described in any aspect of the first aspect and the second aspect, the second information includes the adjusted configuration information of the second cell, and the adjusted configuration information of the second cell includes at least one of the following: identification information of the second cell; adjusted cell coverage status parameters of the second cell; adjusted synchronization signal block coverage status parameters of the second cell; or, the adjusted mobility parameters of the second cell and the identification information of the neighboring cells of the second cell.

[0033] The first network device can determine, based on one or more of the above-mentioned items, 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 the power consumption of the first network device, thereby bringing higher gain to the first network device in solving the CCO problem of the first cell.

[0034] In 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.

[0035] Optionally, the second information may be used to indicate that configuration adjustment of the second cell fails.

[0036] 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 solve the CCO problem of the first cell by itself.

[0037] In the solution described in any aspect of the first aspect and the second aspect, the above-mentioned reason value includes at least one of the following: there is no suitable configuration, or configuration adjustment is not supported.

[0038] Exemplarily, the reason value is that configuration adjustment is 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.

[0039] Exemplarily, the reason value is no suitable configuration, which means: the second network device supports cell configuration adjustment, but no suitable configuration is found this time. When the first network device finds that the cell has a CCO problem later, it can still send the first information to the second network device.

[0040] 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 indicating configuration adjustment of the cell; or, at least one second configuration information and an evaluation indicator, the evaluation indicator indicating an indicator used when evaluating at least one second configuration information.

[0041] 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.

[0042] Optionally, the above-mentioned evaluation index may also be a feedback index, which is used to indicate an index used when providing feedback or evaluating the corresponding second configuration information.

[0043] 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 eliminate the need for the first network device to make major adjustments to the configuration of the first cell, etc. This can bring higher gains to the first network device in solving the CCO problem of the first cell.

[0044] 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, and the adjusted cell coverage status parameters of the cell; the identification information of the cell, and 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.

[0045] The above-mentioned cell may be the first cell, or a neighboring cell of the first cell, for example, the third cell, etc., which is not limited.

[0046] 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.

[0047] 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.

[0048] Optionally, the third configuration information may indicate configuration adjustments that may be taken by the second cell under the corresponding second configuration information.

[0049] Optionally, the configuration information acceptable to the second network device may also be understood as configuration information recommended by the second network device.

[0050] 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.

[0051] 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.

[0052] Through one or more of the above, the second network device can reasonably evaluate each second configuration information, thereby helping the first network device to determine a suitable configuration adjustment plan. In combination with the scheme described in any aspect of the first aspect and the second aspect, 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 corresponds to at least one second configuration information, and the evaluation result corresponds to the evaluation indicator.

[0053] The above evaluation result is obtained by evaluating the corresponding second configuration information according to the evaluation index.

[0054] 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, lower power consumption of the first network device, etc.

[0055] In the solution described in any aspect of the first aspect and the second aspect, the second information includes a reason value for indicating evaluation failure.

[0056] Optionally, the second information mentioned above may indicate that the evaluation has failed.

[0057] The first network device may determine, based on the second information, that the second network device cannot evaluate the second configuration information, and the first network device may determine appropriate second configuration information on its own.

[0058] In 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.

[0059] For example, when the reason value is that no evaluation result is obtained, it may indicate that the second network device has the evaluation function, but did not obtain a suitable evaluation result this time. When the first network device finds the CCO problem again later, it may still send the first information to the second network device.

[0060] Exemplarily, when the cause value is that the evaluation of 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 finds the CCO problem again, it will no longer send the first information to the second network device.

[0099] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0100] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0101] 1. Unless otherwise specified, “at least two or more” means two or more.

[0102] 2. Unless otherwise specified or there is no logical conflict, the terms and / or descriptions between different embodiments of the present application are consistent and can be referenced to each other. The technical features in different embodiments can be combined to form new embodiments based on their internal logical relationships.

[0103] 3. The various digital numbers involved in this application are only used for the convenience of description and are not used to limit the scope of protection of this application. The size of the serial numbers involved in this application does not mean the order of execution. The execution order of each process should be determined by its function and internal logic. For example, the terms "first", "second", "third", "fourth" and other various terminology labels (if any) in the specification and claims and drawings of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. Among them, the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than what is illustrated or described here.

[0104] At the same time, any embodiment or design described in the present application as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0105] 4. The terms "comprise", "include", "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising 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.

[0106] 5. In this application, "used to indicate" can be understood as "enable", and "enable" can include direct enablement and indirect enablement. When describing that a certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and it does not mean that the information must carry A.

[0107] The information enabled by the information is called information to be enabled. In the specific implementation process, there are many ways to enable the information to be enabled, such as but not limited to, the information to be enabled can be directly 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 relationship 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, the enabling of specific information can also be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified by the protocol), thereby reducing the enabling overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and enabled uniformly to reduce the enabling overhead caused by enabling the same information separately.

Among them, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including each network element), and this application does not limit its specific implementation method.

The “and / or” in this application is only a description of the association relationship between the associated objects, indicating that there can be three relationships.

[0113] First, a communication system to which the embodiments of the present application are applicable is described.

[0114] Figure 1 Schematic diagram of a communication system applicable to the embodiment of the present application. Figure 1 As shown, the communication system includes: a network device 110, a network device 120 and a terminal device 130. The terminal device 130 is within the coverage of the network device 110. For example, the network device 110 provides a network access service for the terminal device 130.

[0115] In practical applications, Figure 1 The communication system shown may also include a greater number of terminal devices and network devices, and may also include other devices, such as core network devices, etc., which are not limited to this.

[0116] In an embodiment of the present application, a terminal device is a device with wireless transceiver functions, 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 equipment, user agent or user device.

[0117] In the embodiment of the present application, the terminal device can 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 terminal 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 communication (D2D), 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, and a wireless terminal in industrial control. There is no restriction on wireless terminals in medical, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home, or terminal devices in communication networks evolved after 5G.

[0118] 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 6G and other future communication systems.

[0119] In the embodiment of the present application, the communication device for realizing the function of the terminal device may be the terminal device, or may be a device capable of supporting the terminal device to realize the function, such as a chip system. The device may be installed in the terminal device or used in combination with the terminal device. In the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0120] In the embodiment of the present application, the network device is a device with wireless transceiver function, 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 service gateway (BNG), an aggregation switch or the 3rd Generation Partnership Project (the 3 rd generation partnership project, 3GPP) network equipment, etc.

[0121] The above-mentioned 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), etc. The network equipment can also include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, transmission points (transmitting and receiving points, TRP), transmission points (transmitting points, TP), mobile switching centers, and devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communications, network equipment in non-terrestrial networks (NTN), etc., without specific limitation.

[0122] In an embodiment of the present application, the network device may also include a network element or module that implements some functions of the base station, for example, including 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 radio frequency remote processing 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 the RU in the O-RAN system, etc., without limitation.

[0123] 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, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0124] In the embodiment of the present application, the network device may also be a device with communication functions in a 6G communication system, without limiting the form or type of the network device in 6G and other future communication systems.

[0125] In the embodiment of the present application, the communication device for realizing the function of the network device can be a network device, or a device that can support the network device to realize the function, such as a chip system. The device can be installed in the network device or used in combination with the network device. The chip system in the embodiment of the present application can be composed of a chip, or it can include a chip and other discrete devices.

[0126] The above-mentioned network equipment may include a baseband device and a radio frequency device. The baseband device may be implemented by one node or multiple nodes. The radio frequency device may be implemented independently from the baseband device or integrated in the baseband device, or some functions may be integrated independently and some functions may be integrated in 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 arranged remotely from the baseband device, for example, an RRU is a remote radio unit arranged relative to a BBU.

[0127] The communication between the network equipment and the terminal equipment follows a certain protocol layer structure. For example, the control plane protocol layer structure may include the functions of 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 the PDCP layer, the RLC layer, the MAC layer and the physical layer; in a possible implementation, a service data adaptation protocol (SDAP) layer may also be included above the PDCP layer.

[0128] The network device may implement the functions of the protocol layers such as RRC, PDCP, RLC and MAC by one node, or may implement the functions of these protocol layers by multiple nodes. For example, in an evolutionary structure, the network device includes a CU and a DU, and multiple DUs are centrally controlled by one CU. For example, the CU and the DU may be divided according to the protocol layers of the wireless network, such as the functions of the PDCP layer and above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP, such as the RLC layer and the MAC layer, are set in the DU.

[0129] This division of the protocol layer is only an example. It can also be divided in other protocol layers, such as dividing in the RLC layer, setting the functions of the RLC layer and the protocol layers above in the CU, and the functions of the protocol layers below the RLC layer in the DU; or dividing in a certain protocol layer, for example, setting some functions of the RLC layer and the functions of the protocol layers above the RLC layer in the CU, and setting the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer in the DU. In addition, it can also be divided in other ways, such as dividing by latency, setting the functions whose processing time needs to meet the latency requirements in the DU, and the functions that do not need to meet the latency requirements in the CU.

[0130] 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 partly remotely located and partly integrated in the DU, without any limitation here.

[0131] 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. It is known to those skilled in the art that with the evolution of the communication network architecture and the emergence of new service scenarios, the technical solutions provided by this application are also applicable to similar technical problems. For example, this application can be applied to V2X scenarios.

[0132] To facilitate understanding and explanation, the relevant terms involved in the embodiments of the present application are briefly described below.

[0133] Cell coverage problem: refers to weak coverage at the cell edge or coverage holes. For a description of cell coverage problems, see Figure 2 .

[0134] Figure 2 This is a schematic diagram of the coverage problem of a cell. Figure 2 As shown, cell 1 is a cell of network device 110, terminal device 130 is located in cell 1, cell 2 is a cell of network device 120, and cell 2 is a neighboring cell (or adjacent cell) of cell 1. Terminal device 130 measures cell 1 to obtain or acquire reference signal received power (RSRP) of cell 1 (it may also be to obtain the measurement result of cell 1, RSRP is an example of the measurement result of the cell). When the RSRP of cell 1 is less than 110 dBm (as an example, not limited to), network device 110 may consider that cell 1 has or has a coverage problem.

[0135] The terminal device 130 may also measure the cell 2, obtain or acquire the RSRP of the cell 2 (or obtain the measurement result of the cell 2), and report the RSRP of the cell 2 to the network device 110. The network device 110 may determine whether the cell 1 has or has a coverage problem based on the RSRP of the cell 2. For example, when the RSRP of the cell 2 is lower than a threshold value (e.g., 10 dBm), the network device 110 determines that the cell 1 has a coverage problem.

[0136] Cell capacity problem: refers to the small capacity (or user rate) at the cell edge. For a description of cell capacity problems, see Figure 3 .

[0137] Figure 3 This is a schematic diagram of the cell capacity problem. Figure 3 As shown, cell 1 is a cell of the network device 110, cell 2 is a cell of the network device 120, cell 2 is a neighboring cell of cell 1, and terminal device 130 is located in cell 1. Terminal device 130 is easily affected by cell 2. Terminal device 130 measures cell 1 and cell 2, obtains or acquires RSRP of cell 1 and RSRP of cell 2, and reports RSRP of cell 1 and RSRP of cell 2 to network device 110. When the difference between RSRP of cell 1 and RSRP of cell 2 is less than a threshold value (e.g., 6 dBm), network device 110 may consider that cell 1 has or has a capacity problem.

[0138] 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 great interference to edge users of cell 1. In addition, the capacity problem of the cell may also be expressed as a cell edge capacity problem of the cell.

[0139] In the embodiment of the present application, the coverage problem of the cell and the capacity problem of the cell can be collectively referred to as the CCO problem of the cell. Unless otherwise specified, the types of the CCO problem of the cell will not be distinguished below.

[0140] When the network device 110 detects that a CCO problem exists in cell 1 or occurs, the network device 110 can adjust the configuration of cell 1 (or the cell configuration, which includes but is not limited to: cell coverage, SSB coverage, mobility parameters, etc.), for example, by changing the downlink transmission power of cell 1, the tilt and azimuth of the antenna, etc. to enhance the coverage of cell 1, thereby solving the CCO problem of cell 1.

[0141] However, the above solution may not bring greater benefits to the network device 110 in solving the CCO problem of cell 1 .

[0142] In view of this, the present application provides a communication method, apparatus and system, which can support a network device that detects a CCO problem and solve the CCO problem to bring higher gain.

[0143] The following describes the communication method, device and system according to the embodiments of the present application in conjunction with the accompanying drawings.

[0144] Figure 4 Schematic diagram of an interactive process of a communication method in an embodiment of the present application. Figure 4 As shown, the method includes:

[0145] S401 . The network device 110 (eg, a first network device) sends information 1 (eg, first information) to the network device 120 (eg, a second network device).

[0146] Accordingly, the network device 120 receives information 1. The information 1 indicates information about the CCO problem of the cell 1 (eg, the first cell).

[0147] The network device 120 can determine or obtain information about the CCO problem of the cell 1 according to the information 1. For example:

[0148] Information 1 indicates information about the CCO problem of cell 1 (such as CCO issue / CCO problem / CCO matter / CCOtrouble, etc.);

[0149] Information 1 indicates information related to the CCO problem of cell 1;

[0150] Information 1 includes or carries information about a CCO problem of cell 1;

[0151] Information 1 includes or carries information related to the CCO problem of cell 1; or,

[0152] Information 1 indicates one or more processing strategies for solving the CCO problem of cell 1. The strategy may also be understood as an alternative expression such as a solution or a method, which is not limited thereto.

[0153] In summary, the network device 120 may determine the information of the CCO problem of the cell 1 according to one or more of the above items.

[0154] 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., and are not limited to this.

[0155] In a possible implementation, the network device 120 may determine that the cell 1 has a CCO problem according to the information 1. Based on this, the network device 120 may provide assistance for solving the CCO problem of the cell 1, for example, adjusting the configuration of the cell adjacent to the cell 1 in one or more cells belonging to the network device 120; for example, providing a reference for the network device 110 to determine a suitable configuration adjustment solution. For details, please refer to the following description.

[0156] In the embodiment of the present application, cell 1 belongs to network device 110. The “belongs” mentioned above 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 a subordinate relationship or a subordinate relationship.

[0157] 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 CCO problem of cell 1 is taken as an example for description below, but other expressions are not limited.

[0158] In a possible implementation, the network device 110 may determine whether the cell 1 has a CCO problem by one or more of the following:

[0159] 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);

[0160] 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);

[0161] 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 the network device 110) is less than a threshold value (e.g., 6 dBm); or,

[0162] In cell 1, the 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 the neighboring cell measured is less than a threshold value (for example, 6 dBm).

[0163] Exemplarily, the terminal device 130 measures the cell 1, obtains the RSRP of the cell 1, and reports the RSRP of the cell 1 to the network device 110. When the RSRP of the cell 1 is less than the threshold, the network device 110 determines that the cell 1 has or has a CCO problem (such as a coverage problem).

[0164] Exemplarily, the terminal device 130 measures cell 1 and cell 2 (cell 1 and cell 3 may also be measured, not limited to this), 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 value, the network device 110 determines that a CCO problem (such as a capacity problem) exists or occurs in cell 1.

[0165] Through the above listed conditions, the network device 110 can determine whether there is a CCO problem and the type of the CCO problem in cell 1. For example, if one or both of the first two conditions are met, it can be determined that there is a coverage problem in cell 1, and if one or both of the last two conditions are met, it can be determined that there is a capacity problem in cell 1.

[0166] It should be noted that the above-mentioned conditions are examples and are not intended to be final limitations.

[0167] In a possible implementation, information 1 may include at least one of the following:

[0168] identification information of cell 1;

[0169] The type of CCO problem in cell 1; or,

[0170] Information of terminal devices served by cell 1.

[0171] 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 there is a CCO problem in cell 1. For example, when an embodiment of the present application supports a protocol agreement or configures network device 110 to send identification information of a certain cell to network device 120, the identification information of the cell can be used to indicate that there is a CCO problem in the cell.

[0172] The network device 120 determines that the CCO problem exists in the cell 1 according to the identification information of the cell 1, and determines the cell adjacent to the cell 1 in one or more cells under the jurisdiction of the network device 120. Taking the cell 2 as an example, the network device 120 solves the CCO problem of the cell 1 by adjusting the configuration of the cell 2. In this way, the network device 110 can solve the CCO problem of the cell 1 without adjusting the configuration of the cell 1, which is conducive to reducing the power consumption of the network device 110, thereby bringing greater gain.

[0173] 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.

[0174] 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.

[0175] In one example, information 1 includes the type of the CCO problem of cell 1, and network device 120 determines that a certain cell in network device 110 has a CCO problem, and performs configuration adjustment on a cell adjacent to cell 1 in one or more cells under the jurisdiction of network device 120. In this way, network device 110 can solve the CCO problem of cell 1 without adjusting the configuration of cell 1, which is conducive to reducing the power consumption of network device 110, thereby bringing greater gain.

[0176] The types of CCO problems of cell 1 may include: coverage problems and capacity problems. By distinguishing the types of CCO problems, it is helpful for the network device 120 to determine a suitable strategy for solving the CCO problem of cell 1. For example, for coverage problems, the network device 120 solves the CCO problem of cell 1 by enhancing the coverage of cell 2; for capacity problems, the network device 120 solves the CCO problem of cell 1 by reducing the coverage of cell 2.

[0177] In one example, information 1 includes information of a terminal device served by cell 1, and the information of the terminal device can be used to indicate that a certain cell in network device 110 has a CCO problem. For example, when an embodiment of the present application supports a protocol agreement or configures network device 110 to send information of a terminal device to network device 120, the information of the terminal device can be used to indicate that a certain cell in network device 110 has a CCO problem.

[0178] The network device 120 can adjust the configuration of one or more cells under the jurisdiction of the network device 120 according to the judgment that a certain cell in the network device 110 has a CCO problem, for example, to enhance the coverage of cell 2. In this way, the network device 110 can solve the CCO problem of cell 1 without adjusting the configuration of cell 1, which is conducive to reducing the power consumption of the network device 110.

[0179] 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 other cells (eg, cell 3).

[0180] Through one or more of the above, the network device 120 can obtain or determine the information of the CCO problem of cell 1.

[0181] Optionally, the one or more terminal devices mentioned above 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).

[0182] In a possible implementation, the information of the terminal device served by cell 1 may include at least one of the following:

[0183] Identification information;

[0184] Measurement results for cell 1;

[0185] Measurement results of SSB in cell 1;

[0186] Measurement results for cell 2;

[0187] Measurement results of SSB in cell 2;

[0188] The measurement result of cell 3; or

[0189] Measurement results for SSB in cell 3.

[0190] For example:

[0191] The information of the terminal device includes the identification information of the terminal device. The network device 120 determines the corresponding terminal device according to the identification information of the terminal device, and can determine that there is no data transmission between the terminal device and the network device 120. Further, the network device 120 determines that a certain cell in the network device 110 has a CCO problem, and can screen the cells that need to be configured and adjusted in one or more cells under the jurisdiction of the network device 120 according to this judgment. For example, if it is determined that cell 2 is a cell that needs to be configured and adjusted, the coverage of cell 2 can be enhanced. In this way, the network device 110 can solve the CCO problem of cell 1 without adjusting the configuration of cell 1, which is conducive to reducing the power consumption of the network device 110, thereby bringing greater gains.

[0192] 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 (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 to this.

[0193] For example:

[0194] The information of the terminal device includes the measurement result of the cell 1 , and the network device 120 can determine whether the cell 1 has a CCO problem according to the measurement result of the cell 1 .

[0195] 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.

[0196] For example:

[0197] The information of the terminal device includes the measurement result of the SSB in cell 1, and 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.

[0198] 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).

[0199] 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.

[0200] For example:

[0201] 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 according to the measurement result of cell 2, so as to solve the CCO problem of cell 1.

[0202] 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.

[0203] For example:

[0204] The information of the terminal device includes the measurement results of the 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 the SSB in cell 2, which can help solve the CCO problem of cell 1.

[0205] The SSB 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).

[0206] 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.

[0207] For example:

[0208] The information of the terminal device includes the measurement result of 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; for another example, if the measurement result of cell 3 is less than a threshold, the network device 120 can determine that there may be a CCO problem in cell 1), and then determine whether it is necessary to adjust the configuration of cell 2, which can help solve the CCO problem in cell 1.

[0209] 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.

[0210] For example:

[0211] 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 users in cell 1 are easily affected by cell 3), and then determine whether it is necessary to adjust the configuration of cell 2, which can help solve the CCO problem of cell 1.

[0212] The SSB in cell 3 may include all SSBs in cell 3, or may include only SSBs related to the CCO problem (for example, the SSB that has the strongest interference to the terminal device in cell 1).

[0213] 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.

[0214] 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 according to the measurement results of more neighboring cells of the cell 1.

[0215] 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 gain to the network device 110 in solving the CCO problem of cell 1, for example, saving the power consumption of the network device 110.

[0216] Optionally, the above-mentioned 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, the network device 120 can determine the approximate location of the terminal device, and further determine whether cell 1 has a CCO problem.

[0217] 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, the power consumption of the network device 110 can be reduced.

[0218] In a possible implementation, the information 1 may further include at least one of the following:

[0219] Identification information of cell 2, or at least one first configuration information, where the first configuration information indicates that configuration adjustment is to be performed on cell 2.

[0220] In one example, information 1 includes identification information of cell 2, and network device 120 can determine cell 2 according to the identification information of cell 2, and adjust the configuration of cell 2. For example, the embodiment of the present application can support protocol agreement or configure that when network device 110 sends identification information of a certain cell to network device 120, it is used to indicate that the cell is a cell that needs to be configured and adjusted. In this way, the CCO problem of cell 1 can be solved, thereby bringing greater gains to network device 110 in solving the CCO problem of cell 1, for example, the power consumption of network device 110 can be reduced.

[0221] 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.

[0222] The network device 120 can adjust the configuration of cell 2 according to one or both of the above items, so as to solve the CCO problem of cell 1, thereby bringing higher gain to the network device 110 in solving the CCO problem of cell 1, for example, saving the power consumption of the network device 110.

[0223] In a possible implementation, the first configuration information may include at least one of the following:

[0224] The adjusted cell coverage state parameters of cell 2;

[0225] The adjusted SSB coverage state parameter of cell 2;

[0226] The adjusted mobility parameters of cell 2 and identification information of the neighboring cells of cell 2.

[0227] The network device 120 adjusts the configuration of the cell 2 according to one or more of the above items, so as to solve the CCO problem of the cell 1, thereby bringing higher gain to the network device 110 in solving the CCO problem of the cell 1, for example, saving the power consumption of the network device 110.

[0228] When the first configuration information includes the adjusted cell coverage state parameter of cell 2, the network device 120 adjusts the cell coverage state of cell 2 according to the parameter. The value of the cell coverage state may 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.

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

[0230] Optionally, the adjusted SSB coverage state parameter of cell 2 may also include an SSB index, which may be used to indicate an SSB for which coverage state adjustment is required.

[0231] When the first configuration information includes the adjusted mobility parameter of the cell 2, the network device 120 adjusts the mobility parameter of the cell 2 according to the parameter. The mobility parameter may include a handover trigger value (Handover Trigger) or a change amount of the handover trigger value.

[0232] The mobility parameter can be used to indicate the conditions 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 can switch from cell 2 to the neighboring cell.

[0233] 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 may be applicable to any cell adjacent to cell 1 and under the jurisdiction of network device 120, and is not limited to this.

[0234] In a possible implementation, the information 1 may further include at least one of the following:

[0235] at least one second configuration information, where the second configuration information indicates to adjust the configuration of the cell*;

[0236] 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.

[0237] Cell* can be used to indicate cell 1, and can also be used to indicate 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 takes cell* as an example.

[0238] 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, and the specific description can be found below.

[0239] 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.

[0240] Optionally, the evaluation indicator may also be understood as a feedback indicator, which indicates an indicator used when providing feedback or evaluating at least one second configuration information.

[0241] Optionally, the evaluation index may also be expressed using other terms, which are not limited thereto.

[0242] Optionally, the evaluation index can also be understood as an index for requesting feedback, wherein the evaluation index is used to indicate which indexes are used when requesting the network device 120 to evaluate the second configuration information, or which indexes are fed back after requesting the network device 120 evaluates the second configuration information.

[0243] 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.

[0244] In a possible implementation, the evaluation indicators may include at least one of the following:

[0245] 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 to the at least one second configuration information;

[0246] at least one prediction information, the at least one prediction information corresponds to at least one second configuration information, and the prediction information is used to predict device performance under the corresponding second configuration information;

[0247] The at least one second configuration information is configuration information acceptable to the network device 120 .

[0248] Optionally, the third configuration information mentioned above may indicate configuration adjustments that may be taken by cell 2 under the corresponding second configuration information.

[0249] Optionally, the configuration information acceptable to the network device 120 may also be understood as the configuration information recommended by the network device 120 .

[0250] Through one or more of the above, the network device 120 reasonably evaluates each second configuration information, thereby helping the network device 110 to determine a suitable configuration adjustment solution.

[0251] Exemplary:

[0252] 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.

[0253] For example, when the network device 110 adjusts the configuration of the cell * according to the second configuration information, the network device 120 also needs to make corresponding configuration adjustments to the cell 2. For each second configuration information, the network device 120 needs to determine the corresponding third configuration information, and the third configuration information is used to adjust the configuration of the cell 2. The third configuration information can be understood as the configuration information that the network device 120 may adopt.

[0254] 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.

[0255] Exemplary:

[0256] The evaluation index 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.

[0257] For example, the network device 110 uses the second configuration information to adjust the configuration of the cell *, then the performance of the terminal equipment in the cell * will change to a certain extent, and the network device 120 needs to predict the performance change of the terminal equipment in the cell *.

[0258] In a possible implementation, the above prediction information includes at least one of the following:

[0259] Prediction of measurement results for cell*.

[0260] Prediction of the measurement results of the neighboring cells of cell*.

[0261] Prediction of the measurement results of SSB for cell*.

[0262] Prediction of the measurement results of SSB in the neighboring cells of cell*.

[0263] Indication information 1 (for example, the first indication information), indication information 1 indicates whether the cell* will have a CCO problem.

[0264] 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 a suitable configuration adjustment solution.

[0265] Exemplary:

[0266] 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* after re-measuring the cell*?

[0267] The prediction of the measurement result of the cell* includes at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0268] 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 cell of the cell*?

[0269] 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 equipment in cell*).

[0270] The prediction of the measurement result of the neighboring cell of the cell* includes the identification information of the neighboring cell of the cell* and at least one of the following: a predicted value of RSRP, a predicted value of RSRQ, and a predicted value of SINR.

[0271] After the cell* uses a certain second configuration information to make configuration adjustments, what will be the measurement results of the terminal equipment in the cell* re-measuring the SSB in the cell*?

[0272] 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).

[0273] The prediction of the measurement result of the SSB in the 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.

[0274] After the cell * uses a certain second configuration information to make a configuration adjustment, what will be the measurement result obtained by the terminal equipment in the cell * by re-measuring the SSB in the neighboring cell of the cell *?

[0275] The SSBs in the neighboring cells of cell* may include all SSBs in all neighboring cells of cell*, or may include only SSBs related to the CCO problem (eg, the SSBs that cause the strongest interference to the terminal devices in cell*).

[0276] The prediction of the measurement result of the SSB in the neighboring cell of the cell* includes the identification information of the neighboring cell of the cell*, the SSB index and at least one of the following: the predicted value of RSRP, the predicted value of RSRQ and the predicted value of SINR.

[0277] After cell * uses a certain second configuration information for configuration adjustment, network device 120 also needs to predict whether CCO problem will continue to occur or exist in cell 1 or cell *. Network device 120 can indicate the prediction of whether CCO problem will exist in cell * or cell 1 through indication information 1.

[0278] 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".

[0279] The network device 120 needs to predict each second configuration information to obtain corresponding prediction information.

[0280] The prediction information may be for one terminal device or for multiple terminal devices, and there is no limitation on this.

[0281] The neighboring cells of cell* may include all neighboring cells, or may only include neighboring cells related to the CCO problem (e.g., neighboring cells that have the strongest interference to the terminal devices in cell*)

[0282] Exemplary:

[0283] When the evaluation index includes configuration information acceptable to the network device 120 in at least one second configuration information, it can 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.

[0284] The above evaluation index may include several bits, each bit corresponding to an index. For example, the evaluation index includes 2 bits, the first bit corresponds to the "third configuration information", the second bit corresponds to the "prediction information", and each bit has a value of "1" indicating that the network device 120 is requested to feedback the corresponding index, and a value of "0" indicating that the network device 120 is not requested to feedback the corresponding index.

[0285] Optionally, the evaluation indicator may also be used to request evaluation of acceptable second configuration information or to request feedback of recommended second configuration information. For example, the evaluation indicator is used to indicate whether to request network device 120 to evaluate or provide feedback: whether to accept at least one second configuration information that may be adopted by network device 110, or to accept part of the second configuration information in at least one second configuration information that may be adopted by network device 110, or to recommend to network device 110 the second configuration information in at least one second configuration information that may be adopted by network device 110.

[0286] In a possible implementation, the second configuration information may include at least one of the following:

[0287] identification information of the cell*, and cell coverage status parameters of the adjusted cell*;

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

[0289] The identification information of the cell*, the adjusted mobility parameters of the cell* and the identification information of the neighboring cells of the cell*.

[0290] The network device 120 may determine the configuration adjustments that the network device 110 may make to the cell 1, and thus may help the network device 110 determine the appropriate configuration adjustments.

[0291] 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*.

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

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

[0294] 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.

[0295] In summary, the network device 120 can obtain or determine the information about the CCO problem of the cell 1 through the information 1 .

[0296] S402 , the network device 120 sends information 2 to the network device 110 .

[0297] Accordingly, the network device 110 receives information 2. The information 2 indicates a processing strategy for the CCO problem of the cell 1.

[0298] Information 2 is sent by network device 120 to network device 110 in response to information 1.

[0299] The above-mentioned sending of information 2 in response to information 1 may include: the network device 120 determines the second information 2 according to the first information 1, or the network device 120 refers to the information 1 when determining the information 2. In this way, after receiving the information 1, the network device 120 sends the information 2 to the network device 110, thereby helping the network device 110 determine the processing strategy of the CCO problem of the cell 1.

[0300] Exemplarily, after the network device 120 obtains or determines the information about the CCO problem of cell 1 according to information 1, the network device 120 determines a processing strategy for 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, and 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 scheme for cell 1, so that the network device 110 can select a configuration adjustment scheme with lower power consumption to adjust the configuration of cell 1, which can not only solve the CCO problem of cell 1, but also reduce the power consumption of the network device 110.

[0301] In summary, after determining that there is a CCO problem in cell 1, network device 110 may send information about the CCO problem in cell 1 to network device 120, and network device 120 may indicate a processing strategy for the CCO problem in cell 1 to network device 110 based on the information, and network device 110 processes the CCO problem in cell 1 based on the processing strategy. For example, network device 110 determines a suitable configuration adjustment scheme for cell 1, and the suitable configuration adjustment scheme may enable the first network device to avoid making a large adjustment to the configuration of the first cell, or network device 110 determines that there is no need to solve the CCO problem in cell 1, etc.

[0302] Therefore, 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 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 plan, 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.

[0303] Combined with the following Figure 5-Figure 7 right Figure 4 The method shown is further described.

[0304] Figure 5 FIG. 1 is a schematic diagram of an interaction flow of another communication method according to an embodiment of the present application. Figure 5 As shown, the method includes:

[0305] Optionally, S501: The network device 110 determines that a CCO problem exists in cell 1.

[0306] 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 cell 1 has a CCO problem according to the measurement result of the cell 1 .

[0307] Exemplarily, the terminal device 130 sends the measurement result of cell 1 and the measurement result of cell 2 to the network device 110 , and the network device 110 may determine that the CCO problem exists in cell 1 according to the difference between the measurement result of cell 1 and the measurement result of cell 2 .

[0308] In summary, for the description of the network device 110 determining that the cell 1 has a CCO problem, reference can be made to the description of the aforementioned four conditions, which will not be elaborated herein.

[0309] S502 , the network device 110 sends information 1 to the network device 120 .

[0310] Accordingly, the network device 120 receives information 1, wherein the information 1 indicates information about the CCO problem of the cell 1.

[0311] After the network device 110 determines that the CCO problem exists in the cell 1, the network device 110 determines whether to adjust the configuration of the cell 1. For example, the coverage of the cell 1 is large, and there is no need to expand the coverage of the cell 1. The network device 110 can determine that the network device 120 adjusts the configuration of the cell under the jurisdiction of the network device 120, so as to solve the CCO problem of the cell 1.

[0312] The above-mentioned information 1 may include:

[0313] identification information of cell 1;

[0314] Types of CCO problems in cell 1;

[0315] Information of the terminal device, which belongs to cell 1.

[0316] For the description of the above information, please refer to the previous description and will not be repeated here.

[0317] S503 : The network device 120 adjusts the configuration of the cell 2 .

[0318] After the network device 120 determines that the cell 1 has a CCO problem according to the information 1, a possible implementation is that the network device 120 screens cells adjacent to the cell 1 in one or more cells under the jurisdiction of the network device 120 to determine the cell that needs to be configured and adjusted.

[0319] 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.

[0320] Optionally, the network device 120 may also perform configuration adjustment on one or more cells under the jurisdiction of the network device 120 , without limitation.

[0321] Through the above scheme, when the 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 the network device 120. The network device 120 determines the cell that needs to be configured and adjusted among one or more cells under the jurisdiction of the network device 120 based on the information, thereby helping to solve the CCO problem of cell 1.

[0322] 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 beneficial to reducing the power consumption of the network device 110.

[0323] 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 is conducive to reducing the probability of CCO problem in cell 2 after configuration adjustment.

[0324] Optionally, the method may further include:

[0325] S504a: The network device 120 sends information 2 to the network device 110, where the information 2 includes the adjusted configuration information of the cell 2.

[0326] Accordingly, the network device 110 receives the information 2 .

[0327] For example, the adjusted configuration information of cell 2 may include at least one of the following:

[0328] The adjusted cell coverage status parameters of cell 2;

[0329] The adjusted SSB coverage status parameters in cell 2;

[0330] The adjusted mobility parameters of cell 2 and identification information of the neighboring cells of cell 2.

[0331] 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 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 gain for the network device 110 to solve the CCO problem of cell 1.

[0332] Specifically, the network device 110 may determine whether the CCO problem still exists in the cell 1 according to the adjusted configuration information of the cell 2. When the network device 110 determines that the CCO problem still exists in the cell 1, the network device 110 may send an indication information to the network device 120, where the indication information is used to indicate that the CCO problem still exists in the cell 1, and the network device 120 may optimize the configuration of the cell 2 according to the indication information, so as to solve the CCO problem of the cell 1.

[0333] Optionally, the method may further include:

[0334] 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.

[0335] Accordingly, the network device 110 receives the information 2 .

[0336] Optionally, information 2 may indicate that the configuration adjustment of cell 2 has failed. In a 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 may determine, based on information 2, that the configuration adjustment of cell 2 by network device 120 has failed, and may thereby determine that the CCO problem of cell 1 needs to be solved by network device 110 itself.

[0337] 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 perform the configuration adjustment of cell 2 based on the reason value. The network device 110 can then perform the configuration adjustment of cell 1 or cell 3, thereby solving the CCO problem of cell 1.

[0338] In a possible implementation, the above reason value may include: no suitable configuration, or configuration adjustment is not supported.

[0339] Exemplary:

[0340] The reason value is configuration adjustment not supported, which means that the network device 120 uses a fixed cell configuration and cannot be adjusted. When the network device 110 finds that the cell has a CCO problem later, it will no longer send information 1 to the network device 120.

[0341] Exemplary:

[0342] The reason value is no suitable configuration, which means: the network device 120 supports cell configuration adjustment, but no suitable configuration is found this time. When the network device 110 finds that the cell has a CCO problem later, it can still send information 1 to the network device 120.

[0343] Figure 5 The solution shown is described by taking the example of 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 methods, which can be seen in Figure 6 .

[0344] Figure 6 FIG. 1 is a schematic diagram of an interaction flow of another communication method according to an embodiment of the present application. Figure 6 As shown, the method includes:

[0345] Optionally, S601: The network device 110 determines that a CCO problem exists in cell 1.

[0346] For the description of S601 , refer to the description of S501 .

[0347] S602 . The network device 110 sends information 1 to the network device 120 . The information 1 indicates information about the CCO problem of the cell 1 .

[0348] Accordingly, the network device 120 receives the information 1 .

[0349] The information 1 may include an evaluation index and at least one second configuration information.

[0350] Optionally, the information 1 may also include: identification information of the cell 1; type of the CCO problem of the cell 1; and information of the terminal device.

[0351] For the description of the above information, please refer to the previous article and will not be repeated here.

[0352] For an example description of information 1, please refer to Table 1. The content shown in Table 1 is only an example and is not a final 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 in the previous article, which will not be repeated here.

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

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

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

[0373] ◇Indication information 2, which is used to indicate whether to accept at least one second configuration information. Indication information 2 can be 1 bit: if the value is "1", it means accepting at least one second configuration information that the network device 110 may adopt; if the value is "0",

[0374] This indicates that at least one second configuration information that the network device 110 may adopt is not accepted.

[0375] ◇Indication information 3, the indication information 3 is used to indicate the second configuration information that can be accepted or the second configuration information that is recommended in at least one second configuration information. Indication information 3 can be used to instruct the network device 120 to accept or recommend the second configuration information that the network device 110 may adopt.

[0376] ◇At least one evaluation result, at least one evaluation result corresponds to at least one second configuration information. The evaluation result is determined based on the aforementioned evaluation index, in other words, the evaluation result corresponds to the evaluation index.

[0377] 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 can also bring higher gains, for example, lower power consumption of the network device 110, etc.

[0378] Each of the above evaluation results may include at least one of the following:

[0379] ◇Third configuration information;

[0380] ◇Prediction information.

[0381] For the description of the third configuration information and prediction information, please refer to the previous text and will not be repeated here.

[0382] Optionally, S604b, the network device 120 sends information 2 to the network device 110, where the information 2 includes a reason value for indicating evaluation failure.

[0383] Accordingly, the network device 110 receives the information 2 .

[0384] Optionally, the above-mentioned information 2 may indicate that the evaluation failed. In a possible implementation, the information 2 includes a reason value, which is used to indicate that the evaluation failed. In this way, the network device 110 can determine that the network device 120 fails to evaluate the second configuration information based on the information 2, and can determine that the network device 110 needs to determine the appropriate second configuration information by itself.

[0385] 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 by itself.

[0386] When the network device 120 is unable to evaluate at least one second configuration information, the network device 120 may send a reason value indicating the evaluation failure to the network device 110, and the network device 110 may determine the reason for the evaluation failure of the network device 120 according to the reason value.

[0387] In a possible implementation manner, the above-mentioned reason value may include: no evaluation result is obtained or evaluation of at least one second configuration is not supported, etc.

[0388] Exemplary:

[0389] When the reason value is that no evaluation result is obtained, it may indicate that the network device 120 has the evaluation function, but has not obtained a suitable evaluation result this time. When the network device 110 finds the CCO problem again later, it may still send information 1 to the network device 120 .

[0390] Exemplary:

[0391] 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 finds the CCO problem again, it will no longer send information 1 to the network device 120.
