In the present application, a first network device receives a first message from a second network device for indicating information of CLI measurement, and then the first network device configures the CLI measurement for the terminal device according to the first message. That is, by negotiating the information of the CLI measurement configured for the terminal device between the first network device and the second network device, it helps to avoid the CLI measurement configured for the terminal device by the two network devices exceeding the limit of the CLI measurement of the terminal device.

Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method for configuring CLI measurement and a communication device. Background Art

[0002] Time division duplexing (TDD) is a duplexing method that realizes uplink and downlink transmissions through time division. In the TDD communication mode, reception and transmission in a communication system are performed at different times on the same frequency. When the TDD uplink / downlink ratio (TDD UL / DL pattern) between adjacent cells is different, the transmitted data in one cell may interfere with the received data in another cell, and this interference is called cross link interference (CLI).

[0003] As Figure 1 shown, user equipment (UE) 1 is performing uplink (UL) data transmission, and UE 2 is performing downlink (DL) data reception. Assume that the serving cell of UE 1 is cell1, corresponding to serving base station 1; the serving cell of UE 2 is cell2, corresponding to serving base station 2; cell 1 and cell 2 are two adjacent cells, UE 1 and UE 2 are respectively located at the edges of their serving cells, and the distance between UE 1 and UE 2 is small. From the perspective of the UE: when the UL data transmission of UE 1 and the DL data reception of UE 2 are performed simultaneously, the UL data transmission of UE 1 may cause CLI to the DL data reception of UE 2. From the perspective of the base station: when the DL data transmission of base station 2 and the UL data reception of base station 1 are performed simultaneously, the transmission of base station 2 may cause CLI to the reception of base station 1.

[0004] In summary, how to reduce the impact of CLI on communication is a technical problem that needs to be solved currently. Summary of the Invention

[0005] This application provides a method for configuring CLI measurement and a communication device for optimizing CLI measurement.

[0006] In a first aspect, this application provides a method for configuring CLI measurement. The method includes a first network device receiving a first message from a second network device, and the first network device configuring CLI measurement for a terminal device according to the first message, where the first message is used to indicate information about cross link interference (CLI) measurement.

[0007] This method can be executed by a communication device, and the communication device can be the first network device or a module in the first network device, such as a chip.

[0008] Based on this solution, by negotiating the CLI measurement information configured by the first network device and the second network device for the terminal device respectively, the first network device and the second network device can reasonably configure the CLI measurement information for the terminal device, thereby helping to avoid exceeding the limit of the CLI measurement that the terminal device needs to measure when the first network device and the second network device simultaneously configure the CLI measurement for the same terminal device. Furthermore, in the scenario where the terminal device is connected to the first network device and the second network device simultaneously, the CLI measurement can still be performed normally.

[0009] In this application, the CLI measurement information can be divided into the following two cases.

[0010] Case 1, the CLI measurement information includes the number of CLI measurement resources.

[0011] Based on Case 1, the first message is used to indicate the number of CLI measurement resources configured by the second network device for the terminal device; or, the first message is used to indicate the maximum number of CLI measurement resources allowed to be configured by the first network device for the terminal device; or, the first message is used to indicate the number of CLI measurement resources configured by the second network device for the terminal device per unit time; or, the first message is used to indicate the maximum number of CLI measurement resources allowed to be configured by the first network device for the terminal device per unit time.

[0012] In a possible implementation, if it is determined that the number of CLI measurement resources indicated by the first message does not meet the first threshold, the first network device sends a second message to the second network device; where the second message is used to notify the second network device to adjust the number of CLI measurement resources configured for the terminal device, or to notify the second network device to adjust the number of CLI measurement resources allowed to be configured by the first network device for the terminal device.

[0013] By the first network device sending the second message to the second network device, it helps to avoid the unreasonable number of CLI measurement resources indicated by the first message sent by the second network device to the first network device, resulting in the first network device being unable to configure the CLI measurement for the terminal device.

[0014] Case 2, the CLI measurement information includes the configuration information of the CLI measurement resources.

[0015] Based on Case 2, the first message is used to indicate the configuration information of the CLI measurement resources planned to be configured by the second network device for the terminal device.

[0016] In a possible implementation, the first network device may determine the total number of resources configured for CLI measurement of the terminal device by the first network device and the second network device according to the first message and the configuration information of the resources planned by the first network device for CLI measurement of the terminal device; if the total number is greater than the second threshold, the first network device may adjust the configuration information of the resources planned by the first network device for the terminal device. Here, the second threshold may be the maximum number of resources for CLI measurement; or the maximum number of resources for CLI measurement supported by the terminal device; or the maximum number of resources for CLI measurement within each unit time; or the maximum number of resources for CLI measurement supported by the terminal device within each unit time.

[0017] By the first network device adjusting the configuration information of the resources configured by the first network device for the terminal device, it helps to avoid exceeding the CLI measurement limit of the terminal device when two network devices simultaneously configure the configuration information of the resources for CLI measurement of a terminal device.

[0018] In this application, the first message may also be used to instruct the second network device to configure CLI measurement for the terminal device; or, the first message is used to instruct to allow the first network device to configure CLI measurement for the terminal device; or, the first message instructs the first network device to configure CLI measurement for the terminal device. That is, only one of the first network device and the second network device configures CLI measurement for the terminal device.

[0019] Through negotiation between the first network device and the second network device, it can be achieved that only one network device configures CLI measurement for the terminal device. That is, the terminal device will only receive the configuration of CLI measurement from one network device. In this way, it helps to avoid exceeding the CLI measurement limit required by the terminal device when the first network device and the second network device simultaneously configure CLI measurement for the terminal device, and thus enables the terminal device to still perform normal CLI measurement in the scenario where the terminal device is connected to the first network device and the second network device at the same time.

[0020] Furthermore, optionally, within a preset duration, only one network device configures CLI measurement for the terminal device.

[0021] In a possible implementation, the first network device sends a third message to the second network device, and the third message is used to query whether the first network device is allowed to configure CLI measurement for the terminal device.

[0022] When the first network device needs to configure CLI measurement for the terminal device, by the first network device actively sending the third message to the second network device, it does not need to wait for the second network device to send the first message.

[0023] In a possible implementation, the resource includes a sounding reference signal (SRS) resource or a received signal strength indicator (RSSI) resource.

[0024] In a second aspect, the present application provides a method for configuring CLI measurement. The method includes a second network device determining a first message, and the second network device sending the first message to a first network device, where the first message is used to indicate information about CLI measurement.

[0025] This method can be executed by a communication device, and the communication device can be the second network device or a module in the second network device, such as a chip.

[0026] For the beneficial effects of this solution, please refer to the description of the beneficial effects in the first aspect above, and details are not elaborated here.

[0027] In a possible implementation, the information about CLI measurement includes the number of resources for CLI measurement. Here, the first message is used to indicate the number of resources for CLI measurement configured by the second network device for the terminal device; or, the first message is used to indicate the maximum number of resources for CLI measurement allowed to be configured by the first network device for the terminal device; or, the first message is used to indicate the number of resources for CLI measurement configured by the second network device for the terminal device per unit time; or, the first message is used to indicate the maximum number of resources for CLI measurement allowed to be configured by the first network device for the terminal device per unit time.

[0028] In a possible implementation, the second network device can receive a second message from the first network device and adjust the number of resources for CLI measurement configured by the second network device for the terminal device according to the second message; or, the second network device adjusts the number of resources for CLI measurement allowed to be configured by the first network device for the terminal device according to the second message.

[0029] By the second network device adjusting the number of resources for CLI measurement allowed to be configured by the first network device for the terminal device, or adjusting the number of resources for CLI measurement configured by the second network device for the terminal device, it helps to avoid an unreasonable number of resources for CLI measurement indicated by the first message sent by the second network device to the first network device, resulting in the first network device being unable to configure CLI measurement for the terminal device.

[0030] In a possible implementation, the information about CLI measurement includes the configuration information of the resources for CLI measurement. Here, the first message is used to indicate the configuration information of the resources for CLI measurement planned to be configured by the second network device for the terminal device.

[0031] In a possible implementation, the second network device receives a third message from the first network device, where the third message is used to query whether the first network device is allowed to configure CLI measurement for the terminal device. In this way, the first network device can actively query whether it can configure CLI measurement for the terminal device.

[0032] In a third aspect, the present application provides a method for configuring CLI measurement. The method includes the first network device sending a fourth message to the second network device, where the fourth message is used to notify the second network device that the first network device starts to configure CLI measurement, or is used to notify the second network device that the terminal device is configured with CLI measurement by the first network device, or is used to notify the second network device to prohibit configuring CLI measurement for the terminal device. The first network device configures CLI measurement for the terminal device, and the first network device sends a fifth message to the second network device, where the fifth message is used to indicate that the first network device has completed the configured CLI measurement.

[0033] Based on this solution, by the first network device sending the fourth message to the second network device, it can be achieved that only one first network device configures CLI measurement for the terminal device. That is to say, based on this solution, the terminal device will only receive CLI measurement configured by one network device. In this way, it helps to avoid exceeding the limit of the CLI measurement that the terminal device needs to measure when the first network device and the second network device configure CLI measurement for the terminal device at the same time. Furthermore, in a scenario where the terminal device is connected to the first network device and the second network device at the same time, the terminal device can still perform CLI measurement normally. Further, in this solution, there is no need to negotiate CLI measurement between the first network device and the second network device, which helps to reduce the interaction between the first network device and the second network device.

[0034] In a fourth aspect, the present application provides a method for configuring CLI measurement. The method includes the terminal device sending first capability information to the first network device and sending second capability information to the second network device. The first capability information is determined by the terminal device for the first network device, and the second capability information is determined by the terminal device for the second network device.

[0035] Based on this solution, the first network device can configure CLI measurement for the terminal device according to the first capability information. The second network device can configure CLI measurement for the terminal device according to the second capability information. Exemplarily, the first network device and the second network device can respectively configure the number of resources for CLI measurement for the terminal device, or respectively configure the configuration information for CLI measurement for the terminal device.

[0036] Wherein, the sum of the first capability information and the second capability information does not exceed the total capability information supported by the terminal device.

[0037] In a possible implementation, the first capability information includes a first number of resources measured by CLI determined for the first network device, and the second capability information includes a second number of resources measured by CLI determined for the second network device, where the sum of the first number and the second number is less than or equal to the maximum number of resources measured by CLI supported by the terminal device.

[0038] In another possible implementation, the first capability information includes a third number of resources measured by CLI per unit time determined for the first network device, and the second capability information includes a fourth number of resources measured by CLI per unit time determined for the second network device; the sum of the third number and the fourth number is less than or equal to the maximum number of resources measured by CLI per unit time supported by the terminal device.

[0039] In a possible implementation, the resources include sounding reference signal (SRS) resources or received signal strength indication (RSSI) resources.

[0064] The embodiments of this application will be described in detail below in conjunction with the accompanying drawings.

[0065] Figure 2 is a schematic architecture diagram of an applicable communication system of this application. As Figure 2 shown, the communication system may include a network device 201, a terminal device 202, and a core network device 203. The terminal device communicates with the network device wirelessly, the network device communicates with the core network device wirelessly or wiredly, and the terminal devices communicate with each other wirelessly, for example, by using the sidelink (SL) air interface communication. The core network device and the network device may be independent different physical devices, or the functions of the core network device and the logical functions of the network device may be integrated on the same physical device, or the functions of part of the core network device and part of the network device may be integrated on a physical device. The terminal device may be fixed in position or movable. Figure 2 is only a schematic diagram, and other network devices may also be included in the communication system, such as wireless relay devices and wireless backhaul devices, which are not drawn in Figure 2 . This application does not limit the number of core network devices, network devices, and terminal devices included in the communication system.

[0066] A network device is an access device through which a terminal device accesses the communication system wirelessly. It can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5G communication system, a base station in a future communication system, or an access node in a wireless-fidelity (WiFi) system, etc. It can also be a module or unit that completes some functions of a base station. For example, it can be a central unit (CU) or a distributed unit (DU). Embodiments of this application do not limit the specific technologies and specific device forms adopted by the network device.

[0067] A terminal device can also be referred to as a terminal, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. This application does not limit the specific technologies and specific device forms adopted by the terminal device.

[0068] The network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and can also be deployed on airplanes, balloons, and artificial satellites in the air. This application does not limit the application scenarios of the network device and the terminal device.

[0069] The network device and the terminal device can communicate through licensed spectrum, or through unlicensed spectrum, or simultaneously through licensed spectrum and unlicensed spectrum. The network device and the terminal device can communicate through spectrum below 6 gigahertz (GHz), or through spectrum above 6 GHz, or simultaneously use spectrum below 6 GHz and spectrum above 6 GHz. This application does not limit the spectrum resources used between the network device and the terminal device.

[0070] Based on the above Figure 2The communication system architecture shown below is a possible application scenario provided by this application. That is, the multi-radio dual connectivity (MR-DC) application scenario. MR-DC means that a multi-transmit / multi-receive terminal device simultaneously uses resources (such as time-frequency resources) provided by two nodes (such as network devices). That is to say, a terminal device is simultaneously connected to two nodes (such as network devices). Refer to Figure 3 , where one node is used as the master node (MN), and the other node is used as the secondary node (SN). The MN and the SN are connected through a network interface.

[0071] Based on the type of the MN, the type of the SN, and the difference in the core network connected to the MN, MR-DC can be divided into the following four types.

[0072] Type 1, E-UTRA-NR dual connectivity (EN-DC) (or E-UTRA-NR DC).

[0073] As Figure 4a shown, it is a schematic diagram of an EN-DC architecture provided by this application. The master node in this architecture can be a long term evolution (LTE) eNB, and the secondary node is a new radio (NR) en-gNB. The LTE eNB and the NR en-gNB can be connected to the mobility management entity (MME) or the serving gateway (SGW) in the core network of the 4th Generation mobile communication technology (4G) through the S1 interface. The LTE eNB and the NR gNB can be connected through the X2 interface.

[0074] Type 2, next generation-radio access network E-UTRA-NR dual connectivity (NGEN-DC).

[0075] As Figure 4bAs shown in the figure, it is a schematic diagram of the NGEN-DC architecture provided by this application. The main node in this architecture is the ng-eNB, and the secondary node is the NR gNB. The ng-eNB can also be referred to as the anchor base station. The ng-eNB and the NR gNB are connected to the access and mobility management function (AMF) network element or the user plane function (UPF) network element of the fifth-generation (5G) core network through the NG interface. The NR gNB and the ng-eNB can be connected through the Xn interface.

[0076] Type III, NE-DC (or also known as NR-E-UTRA DC).

[0077] As Figure 4c shown in the figure, it is a schematic diagram of the NE-DC architecture provided by this application. The main node in this architecture is the NR gNB, and the secondary node is the ng-eNB. The NR gNB and the ng-eNB are connected to the AMF network element or the UPF network element of the 5G core network through the NG interface. The NR gNB and the ng-eNB can be connected through the Xn interface.

[0078] Type IV, NR-DC (or also known as NR-NR DC).

[0079] As Figure 4d shown in the figure, it is a schematic diagram of the NR-DC architecture provided by this application. The main node in this architecture is the NR gNB, and the secondary node is the NR gNB. The NR gNB is connected to the AMF network element or the UPF network element of the 5G core network through the NG interface. The NR gNB and the NR gNB can be connected through the Xn interface.

[0080] It should be noted that the network architecture and application scenarios described in this application are for more clearly explaining the technical solutions of this application, and do not constitute a limitation on the technical solutions provided by this application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by this application are equally applicable to similar technical problems.

[0081] The following is an explanation of some terms in this application to facilitate the understanding of those skilled in the art.

[0082] I. Reference Signal Received Power (RSRP)

[0083] RSRP refers to the power value of the reference signal received on all resource elements (REs) carrying the reference signal within a unit time (such as a certain symbol).

[0084] II. Received Signal Strength Indicator (RSSI)

[0085] RSSI refers to the total power value of the received signal, which includes not only the power value of the useful signal or reference signal, but also the power values of interference and thermal noise, etc.

[0086] III. Cross-Link Interference

[0087] When the TDD UL / DL pattern between adjacent cells is different, the transmitted data in one cell may interfere with the received data in another cell, and this kind of interference is called cross-link interference (CLI).

[0088] IV. Cross-Link Interference Measurement (CLI measurement)

[0089] The network device configures CLI measurement for the terminal device. The terminal device measures the configured reference signal (such as the interference source), and then reports the CLI measurement result (such as the intensity of the interference) to the network device. The network device can coordinate scheduling based on the CLI measurement result reported by the terminal device to avoid or mitigate CLI as much as possible.

[0090] V. Types of CLI Measurement

[0091] According to the types of reference signals (i.e., resources) for CLI measurement, CLI measurement can be divided into the following two types. 1) CLISRS-RSRP measurement. In this type of CLI measurement, the reference signal is the SRS resource. The terminal device measures the SRS resources sent by one or more interfering terminal devices (i.e., aggressor terminal devices), and obtains the RSRP results of each SRS resource, that is, the terminal device can measure the interference intensity of each interference source respectively. 2) CLI RSSI measurement. In this type of CLI measurement, the reference signal is the RSSI resource. The terminal device measures the total received power value on the configured RSSI resource. The network device judges the overall interference situation of the terminal device based on the total received power value measured by the terminal device.

[0092] To ensure that the CLI measurement itself does not impose a significant burden on the terminal device, some restrictions are defined for the CLI measurement, which can be divided into the following two aspects: a) The total number of resources of the CLI measurement that the terminal device needs to measure. For example, the total number of CLI SRS resources that the terminal device needs to measure is 32, that is, the maximum number of CLI SRS resources that the terminal device needs to measure is 32. Another example is that the total number of CLI RSSI resources that the terminal device needs to measure is 64, that is, the maximum number of CLI RSSI resources that the terminal device needs to measure is 64. b) The number of resources of the CLI measurement that the terminal device needs to measure within a time slot (slot). For example, the maximum number of CLI SRS resources that the terminal device needs to measure within a time slot is 8.

[0093] Combined with the above MR-DC scenario, a terminal device is connected to two network devices at the same time, that is, a terminal device is connected to an MN and an SN. In the case where both the MN and the SN configure CLI measurements for the terminal device simultaneously, it is possible that the CLI measurements configured by the MN and the SN for the terminal device exceed the specified CLI measurement limits. For example, the total number of SRS resources that the terminal device needs to measure is 32. Among the CLI measurements configured by the MN for the terminal device, there are 20 SRS resources. The SN also configures CLI measurements for the terminal device at the same time, and there are 15 SRS resources in the configured CLI measurements. At this time, the terminal device receives the number of resources of the two CLI measurements, and the sum of the numbers of these two resources is 15 + 20 = 35, which exceeds the total number of SRS resources of 32 that the terminal device needs to measure, and the terminal device cannot perform the CLI measurement normally.

[0094] In view of this, the method for configuring CLI measurement provided in this application is proposed. In the following introduction, this method for configuring CLI measurement can be applied to the network architectures shown in any of the above Figures 2 to 4d figures. In a possible case, the first network device can be the Figure 3 MN above, and the second network device is the Figure 3 SN above. In this case, the first network device can be the Figure 4a LTE eNB above, and the second network device can be the Figure 4a NR gNB above; or the first network device can be the Figure 4b ng-eNB above, and the second network device can be the Figure 4b NR gNB above; or the first network device is the Figure 4c NR gNB above, and the second network device is the Figure 4c ng-eNB above; or the first network device is the Figure 4d NR gNB above, and the second network device is the Figure 4dAnother NR gNB in it. In another possible case, the first network device may be the above-mentioned Figure 3 SN in it, and the second network device is the above-mentioned Figure 3 MN in it. In this case, the first network device may be the above-mentioned Figure 4a NR gNB in it, and the second network device may be the above-mentioned Figure 4a LTE eNB in it; or the first network device may be the above-mentioned Figure 4b NR gNB in it, and the second network device may be the above-mentioned Figure 4b ng-eNB in it; or the first network device is the above-mentioned Figure 4c ng-eNB in it, and the second network device is the above-mentioned Figure 4c NR gNB in it; or the first network device is the above-mentioned Figure 4d NR gNB in it, and the second network device is the above-mentioned Figure 4d Another NR gNB in it. The terminal device may be the terminal device 202 shown in the above-mentioned Figure 2 or may also be the terminal device shown in the above-mentioned Figure 3 terminal device.

[0095] See the following Figure 5 , which is a schematic flowchart of a method for configuring CLI measurement provided by this application. The method includes the following steps:

[0096] Step 501, the second network device sends a first message to the first network device, and the first message is used to indicate the information of CLI measurement. Correspondingly, the first network device receives the first message from the second network device.

[0097] In this application, the information that can be based on CLI measurement includes the number of resources for CLI measurement and the configuration information of CLI measurement. The following takes the information of CLI measurement as the number of resources for CLI measurement and the information of CLI measurement as the configuration information of CLI measurement as examples for introduction.

[0098] Case 1, the information of CLI measurement includes the number of resources for CLI measurement.

[0099] Here, the resources for CLI measurement include time-frequency resources. The resources for CLI measurement are such as CLI SRS resources or CLI-RSSI resources.

[0100] The first message may be used to indicate the number of resources for CLI measurement configured by the second network device for the terminal device. That is to say, the second network device may notify the first network device of the number of resources for CLI measurement configured by the second network device for the terminal device.

[0101] Alternatively, the first message may be used to indicate the maximum number of resources that the first network device is allowed to configure for the terminal device to perform CLI measurement. That is to say, the second network device may notify the first network device of the number of resources that the first network device is allowed to configure for the terminal device to perform CLI measurement.

[0102] Alternatively, the first message may be used to indicate the number of resources that the second network device configures for the terminal device to perform CLI measurement within a unit time. That is to say, the second network device may notify the first network device of the number of resources that the second network device configures for the terminal device to perform CLI measurement within each unit time. Herein, the unit time may be a time slot, a symbol, a subframe, a half frame, a frame, etc.

[0103] Alternatively, the first message may be used to indicate the maximum number of resources that the first network device is allowed to configure for the terminal device to perform CLI measurement within a unit time. That is to say, the second network device may notify the first network device of the maximum number of resources that the first network device is allowed to configure for the terminal device to perform CLI measurement within each unit time. Herein, the unit time may be a time slot.

[0104] In Case 2, the information for CLI measurement includes the configuration information (information element, IE) of the resources for CLI measurement.

[0105] Exemplarily, the configuration information of the resources for CLI measurement includes the time-domain configuration information of the resources, the frequency-domain configuration information of the resources, the period, the identifier of the resources, etc.

[0106] Here, the first message is used to indicate the configuration information of the resources for CLI measurement that the second network device plans to configure for the terminal device.

[0107] In a possible implementation, the type of the first message sent by the second network device to the first network device may be an X2 / Xn message. Further, optionally, when the second network device is an MN and the first network device is an SN, the X2 / Xn message may be a CG-ConfigInfo message; when the second network device is an SN and the first network device is an MN, the X2 / Xn message may be a CG-Config message.

[0108] Step 502, the first network device may configure CLI measurement for the terminal device according to the first message.

[0109] In a possible implementation, after receiving the first message, if the first network device determines that the number of resources for CLI measurement indicated by the first message does not meet the first threshold, the first network device may send a second message to the second network device (see Figure 2In step 503), the second message is used to notify the second network device to adjust the number of resources configured for the terminal device for CLI measurement, or the second message is used to notify the second network device to adjust the number of resources that allow the first network device to configure CLI measurement for the terminal device.

[0110] Here, based on the content indicated by the first message, the following four cases are introduced in detail.

[0111] Case A: The first message is used to indicate the number of resources configured by the second network device for CLI measurement of the terminal device.

[0112] In a possible implementation, the first network device can configure the number of resources for CLI measurement of the terminal device according to the first message and the total number of resources for CLI measurement that the terminal device needs to measure. For example, if the first message is used to indicate that the number of CLI SRS resources configured by the second network device for the terminal device is 10, and the first network device determines, according to the total number of CLI SRS resources 32 that the terminal device needs to measure and the first message, that the number of CLI SRS resources configured for the terminal device is 32 - 10 = 22, the first network device can configure for the terminal device a number of CLI SRS resources less than or equal to 22. Another example, if the first message is used to indicate that the number of CLI RSSI resources configured by the second network device for the terminal device is 15, the first network device can determine, according to the total number of CLI RSSI resources 64 that the terminal device needs to measure and the first message, that the number of CLI RSSI resources configured for the terminal device is 64 - 15 = 49, and the first network device can configure for the terminal device a number of CLI RSSI resources less than or equal to 49.

[0113] Based on Case A, if it is determined that the number of resources indicated by the first message is greater than the first threshold, it means that the number of resources configured by the second network device for CLI measurement of the terminal device is relatively large, which may cause the first network device to be unable to normally configure resources for CLI measurement of the terminal device. The first network device can send a second message to the second network device, and the second message is used to notify the second network device to adjust the number of resources configured for the terminal device for CLI measurement. In a possible implementation, after receiving the second message, the second network device adjusts the number of resources configured for the terminal device for CLI measurement. Further, optionally, after the second network device adjusts the number of resources configured for the terminal device for CLI measurement, it can resend the first message to the first network device. At this time, the number of resources configured by the second network device for CLI measurement of the terminal device indicated by the first message is the adjusted one by the second network device.

[0114] Case B: The first message is used to indicate the maximum number of resources that allow the first network device to configure CLI measurement for the terminal device.

[0115] In a possible implementation, the first network device may determine the maximum number of resources for CLI measurement configured for the terminal device according to the first message. For example, if the first message is used to indicate that the number of CLI SRS resources allowed to be configured by the first network device for the terminal device is 10, the number of CLI SRS resources that the first network device can configure for the terminal device is less than or equal to 10. For another example, if the first message is used to indicate that the number of CLI RSSI resources allowed to be configured by the first network device for the terminal device is 15, the number of CLI RSSI resources that the first network device can configure for the terminal device is less than or equal to 15.

[0116] Based on this Scenario B, if it is determined that the number of resources for CLI measurement indicated by the first message is less than the first threshold, it means that the number of resources for CLI measurement allowed to be configured by the first network device is small, which may cause the first network device to be unable to normally configure the resources for CLI measurement for the terminal device. The first network device sends a second message to the second network device, and the second message is used to notify the second network device to adjust the maximum number of resources for CLI measurement allowed to be configured by the first network device for the terminal device. In a possible implementation, the second network device may adjust the maximum number of resources for CLI measurement allowed to be configured by the first network device for the terminal device based on the second message. Further, optionally, after the second network device adjusts the maximum number of resources for CLI measurement allowed to be configured by the first network device for the terminal device, it may resend the first message to the first network device. At this time, the maximum number of resources for CLI measurement allowed to be configured by the first network device indicated by the first message is the adjusted one by the second network device.

[0117] In Scenario C, the first message may be used to indicate the number of resources for CLI measurement configured by the second network device for the terminal device per unit time. In this Scenario C, the unit time is illustrated by taking one time slot as an example.

[0118] In a possible implementation, the first network device may configure the number of resources for CLI measurement for the terminal device according to the first message and the maximum number of resources for CLI measurement that the terminal device needs to measure within one time slot (slot). For example, if the first message is used to indicate that the number of CLI SRS resources configured by the second network device for the terminal device within one time slot is 6, the first network device may, according to the maximum number of CLI SRS resources 8 that the terminal device needs to measure within one time slot and the first message, configure less than or equal to 8 - 6 = 2 CLI SRS resources for the terminal device within one time slot.

[0119] Based on this situation C, if it is determined that the number of resources indicated by the first message is greater than the third threshold, it means that the number of resources for CLI measurement configured by the second network device for the terminal device per unit time is relatively large, which may cause the first network device to be unable to normally configure resources for CLI measurement for the terminal device. The first network device may send a second message to the second network device, and the second message is used to notify the second network device to adjust the number of resources for CLI measurement configured for the terminal device per unit time. In a possible implementation, after receiving the second message, the second network device adjusts the number of resources for CLI measurement configured for the terminal device per unit time. Further, optionally, after the second network device adjusts the number of resources for CLI measurement configured for the terminal device per unit time, it may resend the first message to the first network device. At this time, the first message is used to indicate that the number of resources for CLI measurement configured by the second network device for the terminal device per unit time is the adjusted number of the second network device.

[0120] Situation D, the first message may be used to indicate the maximum number of resources for CLI measurement that the first network device is allowed to configure for the terminal device per unit time. In this situation D, the unit time is illustrated by taking one time slot as an example.

[0121] In a possible implementation, the first network device may configure the number of resources for CLI measurement for the terminal device according to the first message and the maximum number of resources for CLI measurement that the terminal device needs to measure within one time slot. For example, the first message is used to indicate that the number of CLI SRS resources that the first network device is allowed to configure for the terminal device within one time slot is 6, and the first network device determines that the number of CLI SRS resources that can be configured for the terminal device within one time slot is less than or equal to 6.

[0122] Based on this situation D, if it is determined that the number of resources for CLI measurement indicated by the first message is less than the fourth threshold, it indicates that the number of resources for CLI measurement that the first network device is allowed to configure per unit time is small, which may cause the first network device to be unable to normally configure resources for CLI measurement for the terminal device. The first network device sends a second message to the second network device. The second message is used to notify the second network device to adjust the maximum number of resources for CLI measurement that the first network device is allowed to configure for the terminal device per unit time. In a possible implementation, the second network device may adjust the maximum number of resources for CLI measurement that the first network device is allowed to configure for the terminal device per unit time based on the second message. Further, optionally, after the second network device adjusts the maximum number of resources for CLI measurement that the first network device is allowed to configure for the terminal device per unit time, the second network device may resend the first message to the first network device. At this time, the first message is used to indicate the maximum number of resources for CLI measurement that the first network device is allowed to configure for the terminal device per unit time after the adjustment by the second network device.

[0123] Based on the above situation two, after receiving the first message, the first network device determines the number of resources for CLI measurement that the second network device plans to configure for the terminal device according to the configuration information of the resources for CLI measurement that the second network device plans to configure for the terminal device; then the first network device determines the sum of the number of resources for CLI measurement that the first network device plans to configure for the terminal device and the number of resources for CLI measurement that the second network device plans to configure for the terminal device. If this sum is greater than the second threshold, the first network device needs to adjust the configuration information of the resources for CLI measurement that the first network device plans to configure for the terminal device. Among them, the second threshold may be the maximum number of resources for CLI measurement. For example, the total number of CLI SRS resources that the terminal device needs to measure is 32. Another example is that the total number of CLI RSSI resources that the terminal device needs to measure is 64; the second threshold may also be the maximum number of resources for CLI measurement per unit time. For example, the maximum number of CLI SRS resources that the terminal device needs to measure in a time slot is 8; the second threshold may also be the maximum number of resources for CLI measurement supported by the terminal device; the second threshold may also be the maximum number of resources for CLI measurement supported by the terminal device per unit time.

[0124] As can be seen from the above steps 501 and 502, by negotiating the CLI measurement information configured for the terminal device by the first network device and the second network device respectively, the first network device and the second network device can both reasonably configure the CLI measurement information for the terminal device, which helps to avoid exceeding the limit of the CLI measurement that the terminal device needs to measure when the first network device and the second network device simultaneously configure the CLI measurement for the terminal device. Furthermore, in the scenario where the terminal device is connected to the first network device and the second network device simultaneously, the terminal device can still perform the CLI measurement normally.

[0125] In this application, when a terminal device is connected to two network devices, it is also possible to negotiate through the two network devices so that only one network device configures the CLI measurement for the terminal device. For example, Figure 6 As shown, it is a schematic flowchart of another method for configuring the CLI measurement provided by this application. This method includes the following steps:

[0126] Step 601, the second network device sends a first message to the first network device. Correspondingly, the first network device receives the first message from the second network device.

[0127] Here, the first message is used to indicate that the second network device configures the CLI measurement for the terminal device. That is to say, the first message is used to indicate that the second network device configures the CLI measurement for the terminal device, and the first network device cannot configure the CLI measurement for the terminal device.

[0128] Alternatively, the first message is used to indicate that the first network device is allowed to configure the CLI measurement for the terminal device. It can also be understood that the first message is used to indicate that the first network device is allowed to configure the CLI measurement for the terminal device and the second network device is not allowed to configure the CLI measurement for the terminal device.

[0129] Alternatively, the first message is used to indicate that the first network device configures the CLI measurement for the terminal device. That is to say, the first message is used to indicate that the first network device configures the CLI measurement for the terminal device, and the second network device does not configure the CLI measurement for this terminal device.

[0130] Step 602, the first network device determines whether to configure the CLI measurement for the terminal device according to the first message.

[0131] Here, according to the content indicated by the first message, it can be divided into the following three situations.

[0132] Situation 1, the first message is used to indicate that the second network device configures the CLI measurement for the terminal device.

[0133] Based on this Scenario 1, the first network device can determine, according to the first message, that the second network device configures CLI measurement for the terminal device, and the first network device determines that the first network device cannot configure CLI measurement for the terminal device.

[0134] In Scenario 2, the first message is used to indicate that the first network device is allowed to configure CLI measurement for the terminal device.

[0135] Based on this Scenario 2, the first network device can determine, according to the first message, that the first network device is allowed to configure CLI measurement for the terminal device. In this Scenario 2, the first network device may or may not configure CLI measurement for the terminal device. That is to say, in this Scenario 2, whether the first network device configures CLI measurement for the terminal device can be determined by the first network device itself.

[0136] In Scenario 3, the first message is used to indicate that the first network device configures CLI measurement for the terminal device.

[0137] That is to say, the second network device can directly instruct the first network device to configure CLI measurement for the terminal device, that is, instruct the first network device to configure CLI measurement for the terminal device.

[0138] Furthermore, optionally, the first message can also indicate that within a preset duration corresponding to only one network device configuring CLI measurement for the terminal device. That is to say, the first message can indicate that within the preset duration, the first network device or the second network device configures CLI measurement for the terminal device.

[0139] In this application, the first network device can also actively send a third message to the second network device (see step 603 in Figure 6 ). The third message is used to query whether the first network device is allowed to configure CLI measurement for the terminal device. After receiving the third message, the second network device sends the first message to the first network device to notify the first network device whether it is allowed to configure CLI measurement for the terminal device. When the first network device needs to configure CLI measurement for the terminal device, by actively sending the third message to the second network device, the first network device does not need to wait for the second network device to send the first message.

[0140] It should be noted that configuring CLI measurement for the terminal device includes configuring measurement object configuration information for CLI measurement of the terminal device (for example, configuration information of resources for CLI measurement), reporting configuration information for CLI measurement, and configuration information for measurement quantities of CLI measurement (i.e., filtering configuration).

[0141] As can be seen from the above steps 601 and 602, through negotiation between the first network device and the second network device, it is possible to achieve that only one network device configures CLI measurement for the terminal device. That is to say, based on this solution, the terminal device will only receive CLI measurement configured by one network device. In this way, it helps to avoid exceeding the limit of the CLI measurement that the terminal device needs to measure when the first network device and the second network device configure CLI measurement for the terminal device at the same time. Furthermore, in the scenario where the terminal device is connected to the first network device and the second network device at the same time, the terminal device can still perform CLI measurement normally.

[0142] It should be noted that when the terminal device changes from having only one serving network device (the second network device) to having two serving network devices (the first network device and the second network device), the above Figure 6 second network device can be used as the MN, and the first network device can be used as the SN.

[0143] As Figure 7 shown, it is a schematic flowchart of another method for configuring CLI measurement provided by this application. The method includes the following steps:

[0144] Step 701, the first network device sends a fourth message to the second network device. Correspondingly, the second network device receives the fourth message from the first network device.

[0145] Here, the fourth message is used to notify the second network device that the first network device starts to configure CLI measurement; or the fourth message is used to notify the second network device that the terminal device is configured with CLI measurement by the first network device; or the fourth message is used to notify the second network device to prohibit configuring CLI measurement for the terminal device.

[0146] Step 702, the first network device configures CLI measurement for the terminal device.

[0147] Here, the first network device can configure the measurement object configuration information for the CLI measurement of the terminal device (for example, the configuration information of the resources for CLI measurement), the reporting configuration information for CLI measurement, and the configuration information for the measurement quantity of CLI measurement (i.e., filtering configuration).

[0148] Step 703, after the first network device completes the configured CLI measurement, it sends a fifth message to the second network device. Correspondingly, the second network device receives the fifth message from the first network device.

[0149] Here, the fifth message is used to indicate that the first network device has completed the configured CLI measurement. Or, it can also be understood that the fifth message is used to notify the second network device that the terminal device currently has no configured CLI measurement. It should be understood that the first network device completing the configured CLI measurement means after the first network device removes the CLI measurement configured for the terminal device.

[0150] In a possible implementation, after the second network device receives the fourth message, it can determine that the first network device is configuring CLI measurement for the terminal device. At this time, the second network device does not configure CLI measurement for the terminal device. When the second network device receives the fifth message, it can determine that the first network device has completed the configured CLI measurement. At this time, the second network device can configure CLI measurement for the terminal device.

[0151] It can be seen from the above steps 701 and 703 that by the first network device sending the fourth message to the second network device, it can be realized that only one first network device configures CLI measurement for the terminal device. That is to say, based on this solution, the terminal device will only receive CLI measurement configured by one network device. In this way, it helps to avoid exceeding the limit of the CLI measurement that the terminal device needs to measure when the first network device and the second network device configure CLI measurement for the terminal device at the same time. Furthermore, in a scenario where the terminal device is connected to the first network device and the second network device at the same time, the terminal device can still perform CLI measurement normally. Further, in this solution, there is no need for negotiation of CLI measurement between the first network device and the second network device, which helps to reduce the interaction between the first network device and the second network device.

[0152] In this application, the terminal device can report the capability information of the terminal device to the network device. When a terminal device is connected to two network devices, the terminal device can reasonably plan the capability information reported to the first network device and the second network device so that the CLI measurement configured by the first network device and the second network device for the terminal device does not exceed the total capability of the terminal device. As Figure 8 shown, it is a schematic flowchart of another method for configuring CLI measurement provided by this application. The method includes the following steps:

[0153] Step 801, the terminal device sends the first capability information to the first network device, and the first capability information is determined by the terminal device for the first network device. Correspondingly, the first network device receives the first capability information from the terminal device.

[0154] Step 802, the terminal device sends the second capability information to the second network device, and the second capability information is determined by the terminal device for the second network device. Correspondingly, the second network device receives the second capability information from the terminal device.

[0155] Here, the sum of the first capability information and the second capability information does not exceed the total capability information supported by the terminal device.

[0156] Based on this solution, the first network device can configure CLI measurement for the terminal device according to the first capability information. The second network device can configure CLI measurement for the terminal device according to the second capability information. Exemplarily, the first network device and the second network device can respectively configure the number of resources for CLI measurement for the terminal device, or respectively configure the configuration information for CLI measurement for the terminal device.

[0157] In a possible implementation, the first capability information includes the first number of resources for CLI measurement determined for the first network device, and the second capability information includes the second number of resources for CLI measurement determined for the second network device; wherein, the sum of the first number and the second number is less than or equal to the maximum number of resources for CLI measurement supported by the terminal device.

[0158] Exemplarily, the first capability information includes the first number of CLI SRS resources supported by the terminal device, and the second capability information includes the second number of CLI SRS resources supported by the terminal device. Or the first capability information includes the first number of CLI RSSI resources supported by the terminal device, and the second capability information includes the second number of CLI SRS resources supported by the terminal device.

[0159] Combined with the above Figure 3 , the first capability information reported by the terminal device to the MN is: the first number K1 of CLI SRS resources supported by the terminal device; the second capability information reported by the terminal device to the SN is: the second number K2 of CLI SRS resources supported by the terminal device; the total number of CLI SRS resources supported by the terminal device is K, where K1 + K2 ≤ K.

[0160] Or, the first capability information reported by the terminal device to the MN is: the first number L1 of CLI RSSI resources supported by the terminal device; the second capability information reported by the terminal device to the SN is: the second number L2 of CLI RSSI resources supported by the terminal device; the total number of CLI RSSI resources supported by the terminal device is L, where L1 + L2 ≤ L.

[0161] In another possible implementation, the first capability information includes the third number of resources for CLI measurement determined for the first network device per unit time, and the second capability information includes the fourth number of resources for CLI measurement determined for the second network device per unit time; the sum of the third number and the fourth number is less than or equal to the maximum number of resources for CLI measurement supported by the terminal device per unit time.

[0162] Exemplarily, the first capability information includes the third number of CLI SRS resources supported by the terminal device per unit time, and the second capability information includes the fourth number of CLI SRS resources supported by the terminal device per unit time. Alternatively, the first capability information includes the third number of CLI RSSI resources supported by the terminal device per unit time, and the second capability information includes the fourth number of CLI RSSI resources supported by the terminal device per unit time.

[0163] Combined with the above Figure 3 , the first capability information reported by the terminal device to the MN is: the third number M1 of CLI SRS resources supported by the terminal device per unit time; the second capability information reported by the terminal device to the SN is: the fourth number M2 of CLI SRS resources supported by the terminal device per unit time; the total number of CLI SRS resources supported by the terminal device is M, where M1 + M2 ≤ M.

[0164] Alternatively, the first capability information reported by the terminal device to the MN is: the first number N1 of CLI RSSI resources supported by the terminal device per unit time; the second capability information reported by the terminal device to the SN is: the second number N2 of CLI RSSI resources supported by the terminal device per unit time; the total number of CLI RSSI resources supported by the terminal device is N, where N1 + N2 ≤ N.

[0165] It should be noted that there is no sequence between the above step 801 and step 802. Step 801 can be executed first and then step 802; or step 802 can be executed first and then step 801; or step 801 and step 802 can be executed simultaneously.

[0166] As can be seen from the above step 801 and step 802, the terminal device reasonably allocates the capability information to the first network device and the second network device according to the total supported capability information. The sum of the first capability information and the second capability information does not exceed the total supported capability information of the terminal device. In this way, it can be ensured that the CLI measurement configured by the first network device for the terminal device based on the first capability information and the CLI measurement configured by the second network device for the terminal device based on the second capability information do not exceed the total supported capability information of the terminal device. Furthermore, in the scenario where the terminal device is connected to the first network device and the second network device simultaneously, the terminal device can still perform CLI measurement normally. Further, in this solution, there is no need for the first network device and the second network device to negotiate CLI measurement, which helps to reduce the interaction between the first network device and the second network device.

[0167] In this application, the resources for CLI measurement include the SRS resources for CLI measurement or the RSSI resources for CLI measurement.

[0168] It should be noted that the content indicated by the first message, the second message, the third message, the fourth message, and the fifth message in this application can be pre-agreed between the first network device and the second network device, or can be predefined by the protocol. This application does not make any limitations in this regard. Here, these messages can be identified by an index, or can also be identified by one or more bit information, or may also be in any other possible form. This application does not make any limitations in this regard. In addition, the content indicated by the first message, the second message, the third message, the third message, the fourth message, and the fifth message can also be indicated by a certain field in the message.
