Measurement report reporting method and device

Abstract

The present application relates to the technical field of communications, and provides a measurement report reporting method and device. In the method, a network node can indicate to a terminal M measurement signals of a first cell and a first condition associated with the configuration of the M measurement signals, so that the terminal can send a measurement report for all or some of the M measurement signals to the network node when the first condition is satisfied, wherein the first cell is a candidate target cell for LTM handover, the first condition is a condition for signal quality of the measurement signals, and M is a positive integer. In the process, the terminal does not need to periodically send the measurement report to the network node; instead, the terminal sends the measurement report to the network node only when the measured signal quality satisfies the first condition, thereby reducing the resource overhead.

Method and device for reporting measurement reports

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 1, 2024, with application number 202410404582.3 and invention name “Method and device for reporting measurement reports”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method and apparatus for reporting a measurement report. Background Art

[0003] In a communication system, in order to ensure the service continuity of a terminal, before the terminal moves out of the serving cell, the access network node may switch the terminal to a target cell so that the target cell can continue to provide services to the terminal. Taking layer 1 or layer 2 triggered mobility (LTM) switching as an example, the access network node may configure the terminal to measure the signal quality of the neighboring cell based on the layer 3 (L3) measurement results reported by the terminal. Accordingly, the terminal can measure the neighboring cell according to the configuration of the access network node and periodically report a measurement report, which includes the layer 1 (L1) measurement results of the terminal on the neighboring cell, so that the access network node can determine whether the terminal performs a cell handover based on the measurement report. However, the above-mentioned method of the terminal reporting the measurement report has the problem of large resource overhead. Summary of the Invention

[0004] This application provides a method and apparatus for reporting measurement reports, which can reduce resource overhead.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a method for reporting a measurement report is provided, which can be executed by a terminal. The terminal here can refer to the terminal itself or a processor, circuit, module, logical node, chip, or chip system that implements the method in the terminal.

[0007] The method includes: receiving information about a first configuration and a second configuration from a first network node, and sending a first measurement report to the first network node if a first condition is met. The first configuration information includes information about M measurement signals of a first cell, where the first cell is a candidate target cell for a layer 1 or layer 2 triggered mobility handover; the second configuration information includes information about a first condition, where the first condition is associated with the first configuration and is a condition regarding the signal quality of the measurement signals, where M is a positive integer. The first measurement report includes measurement results of N measurement signals, where the M measurement signals include N measurement signals, where N is an integer greater than 0 and less than or equal to M.

[0008] Based on the method provided in the first aspect above, the terminal does not need to periodically send the first measurement report, but only sends the first measurement report when the first condition is met, thereby reducing resource overhead. In addition, the first condition is a condition for the signal quality of the measurement signal, so the first condition can be set so that the terminal sends the first measurement report when cell switching is required, and does not send the first measurement report when cell switching is not required, thereby avoiding unnecessary signaling overhead. For example, the satisfaction of the first condition is associated with poor signal quality of the serving cell. In this case, the terminal is more likely to perform cell switching, so the terminal can send the first measurement report to perform cell switching; the failure to meet the first condition is associated with good signal quality of the serving cell. In this case, the terminal does not need to perform cell switching, so the terminal does not send the first measurement report.

[0009] In one possible implementation, the first condition includes at least one of the following: the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to a first threshold; the quality of the measurement signal of the first cell is greater than or equal to a second threshold; the quality of the measurement signal of the serving cell is less than or equal to a third threshold. For example, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold, and the quality of the measurement signal of the first cell is greater than or equal to the second threshold. Alternatively, the first condition includes that the quality of the measurement signal of the first cell is greater than or equal to the second threshold, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, the quality of the measurement signal of the first cell is greater than or equal to the second threshold value, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold value.

[0010] Based on the foregoing possible implementation manner, the terminal may determine whether to send the first measurement report according to the foregoing first condition.

[0011] In one possible implementation, the information about the first condition includes at least one of a first threshold value, a second threshold value, or a third threshold value. For example, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, the information about the first condition includes the first threshold value. Alternatively, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, and the quality of the measured signal of the first cell is greater than or equal to the second threshold value, the information about the first condition includes the first threshold value and the second threshold value. Alternatively, when the first condition includes that the quality of the measured signal of the first cell is greater than or equal to the second threshold value, and the quality of the measured signal of the serving cell is less than or equal to the third threshold value, the information about the first condition includes the second threshold value and the third threshold value. Alternatively, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, and the quality of the measured signal of the serving cell is less than or equal to the third threshold value, the information about the first condition includes the first threshold value and the third threshold value. Alternatively, when the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, the quality of the measurement signal of the first cell is greater than or equal to the second threshold value, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold value, the information of the first condition includes the first threshold value, the second threshold value and the third threshold value.

[0012] Based on the possible implementation manner described above, the terminal may determine the corresponding first condition through a threshold value.

[0013] In one possible implementation, satisfying the first condition includes at least one of the following: the difference between the best signal quality among the M measurement signals and the best signal quality among the measurement signals of the serving cell is greater than or equal to a first threshold value; the best signal quality among the M measurement signals is greater than or equal to a second threshold value; and the best signal quality among the measurement signals of the serving cell is less than or equal to a third threshold value.

[0014] It can be understood that the best signal quality among the above-mentioned M measurement signals can be replaced by the signal quality of any one of the M measurement signals, or by the worst signal quality among the M measurement signals. And / or, the best signal quality among the measurement signals of the serving cell can be replaced by the signal quality of any one of the measurement signals of the serving cell, or by the worst signal quality among the measurement signals of the serving cell. For example, satisfying the first condition may mean that the difference between the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) and the best signal quality among the measurement signals of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is greater than or equal to a threshold value of 1. Alternatively, satisfying the first condition may mean that the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) is greater than or equal to a threshold value of 2, and the best signal quality among the measurement signals of the serving cell is less than or equal to a threshold value of 3. Alternatively, satisfying the first condition may mean that: the difference between the best signal quality of the M measurement signals (or the signal quality of any one of the M measurement signals) and the best signal quality of the measurement signal of the serving cell is greater than or equal to a threshold value of 4, and the best signal quality of the measurement signal of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is less than or equal to a threshold value of 5. Alternatively, satisfying the first condition may mean that: the best signal quality of the M measurement signals (or the signal quality of any one of the M measurement signals) is greater than or equal to a threshold value of 6, and the best signal quality of the measurement signal of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is less than or equal to a threshold value of 7, and the best signal quality of the M measurement signals is greater than or equal to a threshold value of 8. Alternatively, satisfying the first condition may mean that: the difference between the best signal quality of the M measurement signals and the best signal quality of the measurement signal of the serving cell is greater than or equal to a threshold value of 9, and the best signal quality of the measurement signal of the serving cell is less than or equal to a threshold value of 10.

[0015] Based on the possible implementations described above, it may be determined whether the first condition is met.

[0016] In a possible implementation, the M measurement signals are M synchronization signal blocks, or M channel state information reference signals.

[0017] Based on the above possible implementation, the terminal may measure the signal quality of M synchronization signal blocks and, if the first condition is met, report a measurement report for the M synchronization signal blocks. Alternatively, the terminal may measure the signal quality of M channel state information reference signals and, if the first condition is met, report a measurement report for the M channel state information reference signals.

[0018] In a possible implementation manner, the second configuration information is further used to indicate that the reporting type of the first measurement report is event reporting.

[0019] Based on the foregoing possible implementation manner, the terminal may report the first measurement report based on an event, such as reporting the first measurement report when the first condition is met.

[0020] In a possible implementation manner, the first measurement report further includes measurement results of Q measurement signals, where the Q measurement signals are configured using information of a third configuration, and the third configuration is different from the first configuration.

[0021] Based on the above possible implementation methods, the first network node can not only determine whether the terminal performs cell switching based on the measurement results of N measurement signals, but also determine whether the terminal performs cell switching based on the measurement results of Q measurement signals. It can be understood that for the terminal, the N measurement signals are not necessarily the measurement signals with the best signal quality, so the first network node can determine a measurement signal with better signal quality for the terminal by combining the measurement results of the N measurement signals and the measurement results of the Q measurement signals, so that the terminal can switch to the beam where the measurement signal is located, thereby ensuring the communication quality of the terminal. In addition, if the beam where each measurement signal in the Q measurement signals is located is a fine beam, such as the beam of the channel state information reference signal, the terminal switches to the fine beam without performing beam alignment, thereby reducing the delay of beam alignment.

[0022] In a possible implementation manner, the method further includes: receiving first indication information from the first network node; and in response to the first indication information, the first measurement report further includes measurement results of the Q measurement signals.

[0023] Based on the foregoing possible implementation manner, the terminal may include the measurement results of the Q measurement signals in the first measurement report based on the instruction of the first network node.

[0024] In one possible implementation, the method further includes: receiving a handover command from the first network node in response to the first measurement report, the handover command indicating handover to the first cell and indicating a first measurement signal, the N measurement signals including the first measurement signal; in response to the handover command, switching to the first cell; and communicating with the first cell based on the first measurement signal.

[0025] Based on the above possible implementation manner, the terminal may be switched to the first cell and communicate with the first cell through the first measurement signal to ensure the communication quality of the terminal.

[0026] In a second aspect, a method for reporting a measurement report is provided. The method can be performed by a first wireless network node. The first network node herein can refer to the first network node itself, or can refer to a processor, circuit, module, logical node, chip, or chip system in the first network node that implements the method. Exemplarily, the first network node is an access network node, a centralized unit, or a distributed unit.

[0027] The method includes: sending information about a first configuration and information about a second configuration to a terminal, and receiving a first measurement report sent by the terminal under a first condition. The first configuration information includes information about M measurement signals of a first cell, where the first cell is a candidate target cell for mobility handover triggered by layer 1 or layer 2; the second configuration information includes information about a first condition, where the first condition is associated with the first configuration and is a condition regarding the signal quality of the measurement signal, where M is a positive integer. The first measurement report includes measurement results of N measurement signals, where the M measurement signals include N measurement signals, where N is an integer greater than 0 and less than or equal to M.

[0028] Based on the method provided in the second aspect above, the first network node can configure a condition for measuring the signal quality of the signal for the terminal, so the terminal does not need to periodically send the first measurement report, but only sends the first measurement report when the first condition is met, thereby reducing resource overhead. In addition, the first condition is a condition for measuring the signal quality of the signal, so the first condition can be set so that the terminal sends the first measurement report when cell switching is required, and does not send the first measurement report when cell switching is not required, thereby avoiding unnecessary signaling overhead. For example, the satisfaction of the first condition is associated with poor signal quality of the serving cell. In this case, the terminal is more likely to perform cell switching, so the terminal can send the first measurement report to perform cell switching; the failure to meet the first condition is associated with good signal quality of the serving cell. In this case, the terminal does not need to perform cell switching, so the terminal does not send the first measurement report.

[0029] In one possible implementation, the first condition includes at least one of the following: the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to a first threshold; the quality of the measurement signal of the first cell is greater than or equal to a second threshold; the quality of the measurement signal of the serving cell is less than or equal to a third threshold. For example, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold, and the quality of the measurement signal of the first cell is greater than or equal to the second threshold. Alternatively, the first condition includes that the quality of the measurement signal of the first cell is greater than or equal to the second threshold, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold. Alternatively, the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, the quality of the measurement signal of the first cell is greater than or equal to the second threshold value, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold value.

[0030] Based on the possible implementation manner described above, the terminal may determine whether to send the first measurement report according to the first condition described above.

[0031] In one possible implementation, the information about the first condition includes at least one of a first threshold value, a second threshold value, or a third threshold value. For example, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, the information about the first condition includes the first threshold value. Alternatively, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, and the quality of the measured signal of the first cell is greater than or equal to the second threshold value, the information about the first condition includes the first threshold value and the second threshold value. Alternatively, when the first condition includes that the quality of the measured signal of the first cell is greater than or equal to the second threshold value, and the quality of the measured signal of the serving cell is less than or equal to the third threshold value, the information about the first condition includes the second threshold value and the third threshold value. Alternatively, when the first condition includes that the difference between the quality of the measured signal of the first cell and the quality of the measured signal of the serving cell is greater than or equal to the first threshold value, and the quality of the measured signal of the serving cell is less than or equal to the third threshold value, the information about the first condition includes the first threshold value and the third threshold value. Alternatively, when the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, the quality of the measurement signal of the first cell is greater than or equal to the second threshold value, and the quality of the measurement signal of the serving cell is less than or equal to the third threshold value, the information of the first condition includes the first threshold value, the second threshold value and the third threshold value.

[0032] Based on the foregoing possible implementation manner, the first network node may indicate the corresponding first condition to the terminal through a threshold value.

[0033] In one possible implementation, satisfying the first condition includes at least one of the following: the difference between the best signal quality among the M measurement signals and the best signal quality among the measurement signals of the serving cell is greater than or equal to a first threshold value; the best signal quality among the M measurement signals is greater than or equal to a second threshold value; and the best signal quality among the measurement signals of the serving cell is less than or equal to a third threshold value.

[0034] It can be understood that the best signal quality among the above-mentioned M measurement signals can be replaced by the signal quality of any one of the M measurement signals, or by the worst signal quality among the M measurement signals. And / or, the best signal quality among the measurement signals of the serving cell can be replaced by the signal quality of any one of the measurement signals of the serving cell, or by the worst signal quality among the measurement signals of the serving cell. For example, satisfying the first condition may mean that the difference between the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) and the best signal quality among the measurement signals of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is greater than or equal to a threshold value of 1. Alternatively, satisfying the first condition may mean that the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) is greater than or equal to a threshold value of 2, and the best signal quality among the measurement signals of the serving cell is less than or equal to a threshold value of 3. Alternatively, satisfying the first condition may mean that: the difference between the best signal quality of the M measurement signals (or the signal quality of any one of the M measurement signals) and the best signal quality of the measurement signal of the serving cell is greater than or equal to a threshold value of 4, and the best signal quality of the measurement signal of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is less than or equal to a threshold value of 5. Alternatively, satisfying the first condition may mean that: the best signal quality of the M measurement signals (or the signal quality of any one of the M measurement signals) is greater than or equal to a threshold value of 6, and the best signal quality of the measurement signal of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is less than or equal to a threshold value of 7, and the best signal quality of the M measurement signals is greater than or equal to a threshold value of 8. Alternatively, satisfying the first condition may mean that: the difference between the best signal quality of the M measurement signals and the best signal quality of the measurement signal of the serving cell is greater than or equal to a threshold value of 9, and the best signal quality of the measurement signal of the serving cell is less than or equal to a threshold value of 10.

[0035] Based on the possible implementation manner described above, the terminal may determine whether the first condition is met.

[0036] In a possible implementation manner, the method further includes: determining information of the first configuration and information of the second configuration.

[0037] Based on the above possible implementation manner, the first network node may determine the first configuration information and the second configuration information, and send the first configuration information and the second configuration information to the terminal. For example, if the first cell belongs to the first network node, the first network node may determine the first configuration information and the second configuration information.

[0038] In a possible implementation manner, the method further includes: receiving first configuration information from a second network node that manages the first cell; and determining second configuration information.

[0039] Based on the above possible implementation, the first network node may obtain the first configuration information from the second network node, determine the second configuration information, and send the first configuration information and the second configuration information to the terminal. For example, if the first cell belongs to the second network node, the first network node may obtain the first configuration information from the second network node and determine the second configuration information itself.

[0040] In a possible implementation, the M measurement signals are M synchronization signal blocks, or M channel state information reference signals.

[0041] Based on the above possible implementation, the terminal may measure the signal quality of M synchronization signal blocks and, if the first condition is met, report a measurement report for the M synchronization signal blocks. Alternatively, the terminal may measure the signal quality of M channel state information reference signals and, if the first condition is met, report a measurement report for the M channel state information reference signals.

[0042] In a possible implementation manner, the second configuration information is further used to indicate that the reporting type of the first measurement report is event reporting.

[0043] Based on the above possible implementation manner, the terminal may report the first measurement report based on an event, such as reporting the first measurement report when the first condition is met.

[0044] In a possible implementation, the first measurement report further includes measurement results of Q measurement signals, where the Q measurement signals are configured using information of a third configuration, and the third configuration is different from the first configuration.

[0045] Based on the above possible implementation methods, the first network node can not only determine whether the terminal performs cell switching based on the measurement results of N measurement signals, but also determine whether the terminal performs cell switching based on the measurement results of Q measurement signals. It can be understood that for the terminal, the N measurement signals are not necessarily the measurement signals with the best signal quality, so the first network node can determine a measurement signal with better signal quality for the terminal by combining the measurement results of the N measurement signals and the measurement results of the Q measurement signals, so that the terminal can switch to the beam where the measurement signal is located, thereby ensuring the communication quality of the terminal. In addition, if the beam where each measurement signal in the Q measurement signals is located is a fine beam, such as the beam of the channel state information reference signal, the terminal switches to the fine beam without performing beam alignment, thereby reducing the delay of beam alignment.

[0046] In a possible implementation manner, the method further includes: sending first indication information to the terminal, where the first indication information is used to instruct to report a measurement result of a measurement signal different from the first configuration.

[0047] Based on the foregoing possible implementation manner, the terminal may include, in the first measurement report based on the instruction of the first network node, measurement results of measurement signals different from the first configuration, such as measurement results of Q measurement signals.

[0048] In a possible implementation, the method further includes: sending a handover command to the terminal in response to the first measurement report, where the handover command indicates handover to the first cell and indicates a first measurement signal, and the N measurement signals include the first measurement signal.

[0049] Based on the above possible implementation manner, the terminal may be switched to the first cell and communicate with the first cell through the first measurement signal to ensure the communication quality of the terminal.

[0050] In one possible implementation, the method further includes: sending notification information to a second network node that manages the first cell, where the notification information is used to indicate that a handover command has been sent, the notification information including identification information of a transmission configuration indication status of the first cell and second indication information, where the second indication information is used to indicate accessing the first cell via random access or accessing the first cell via non-random access.

[0051] Based on the above possible implementation manner, the second network node can be informed of when the transmission configuration indication state of the first cell indicated in the notification information can be used, thereby avoiding resource waste.

[0081] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0082] The method provided in this application can be used in various communication systems. For example, the communication system can be a universal mobile telecommunications system (UMTS) system, a long term evolution (LTE) system, a fifth generation (5G) communication system, a wireless fidelity (WiFi) system, a communication system related to the third generation partnership project (3GPP), a communication system evolved after 5G (such as: a sixth generation (6G) communication system), or a system integrating multiple systems, etc., without limitation. Among them, 5G can also be called new radio (NR). The method provided in this application is described below using the communication system 1000 shown in Figure 1 as an example. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.

[0083] As shown in Figure 1, a schematic diagram of the architecture of the communication system 1000 provided in this application is provided. In Figure 1, the communication system 1000 includes a radio access network (RAN) 100. Optionally, the communication system 1000 also includes a core network (CN) 200 and / or the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (such as 120a-120j in Figure 1, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal 120 is connected to the RAN node 110 wirelessly. The RAN node 110 is connected to the core network 200 wirelessly or wiredly. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices, or they can be the same physical device that integrates the core network logical functions and the radio access network logical functions. The RAN 100 and / or the core network 200 may also be connected to the Internet 300 via wireless or wired means.

[0084] The RAN 100 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a WiFi system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0085] RAN node 110, sometimes also referred to as access network equipment, RAN entities, access nodes, or network equipment, constitutes part of a communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in communication system 1000 can be of the same type or different types.

[0086] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Alternatively, a RAN node may be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle-to-everything (V2X) technology may be a roadside unit (RSU).

[0087] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0088] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0089] In one possible design, a RAN node includes a CU and at least one DU. The DU can be responsible for processing functions with high real-time requirements, such as those of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. The CU can be responsible for processing non-real-time functions, such as those of the service data adaptation protocol (SDAP) layer, the radio resource control (RRC) layer, and the packet data convergence protocol (PDCP) layer. The CU and DU can communicate through the F1 interface.

[0090] For example, taking a RAN node 110a including one CU and two DUs, the architecture of RAN node 110a may be as shown in FIG2 . In FIG2 , RAN node 110a includes CU 1101, DUs 1102 and 1103, which communicate with CU 1101 via an F1 interface. CU 1101 may communicate with RAN node 110b via an Xn interface. RAN node 110a and RAN node 110b may communicate with core network 200 via an NG interface.

[0091] The terminal in this application, for example, terminal 120 is a device with wireless transceiver capabilities. The terminal can be deployed on land, including indoors, outdoors, handheld or vehicle-mounted; it can also be deployed on the water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal can also be called a terminal device, and the terminal device can be a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., or a device for providing voice or data connectivity to users. Among them, UE includes handheld devices with wireless communication capabilities, vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed railways, etc.), wearable devices (such as smart watches, smart bracelets, pedometers, etc.) or computing devices. Exemplarily, UE can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a satellite terminal or a computer with wireless transceiver capabilities. A UE may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless modem, a smart point of sale (POS) machine, customer-premises equipment (CPE), an intelligent robot, a robotic arm, workshop equipment, smart home devices (e.g., refrigerators, televisions, air conditioners, electric meters, etc.), a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in intelligent transportation, a wireless terminal in a smart city, a wireless terminal in a smart home, an in-vehicle terminal, an RSU with terminal functions, or an aerial device (e.g., an intelligent robot, a hot air balloon, a drone, an airplane), etc. A terminal may also be other devices with terminal functions, for example, a terminal may also be a device that functions as a terminal in device-to-device (D2D) communication.

[0092] As an example and not a limitation, in this application, the terminal may be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. For example, a wearable device is not only a hardware device, but also a device that achieves powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as devices that focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0093] In this application, a terminal may be a terminal in an Internet of Things (IoT) system. IoT is an important component of future information technology development. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network that interconnects humans and machines and things. The terminal in this application may be a terminal in machine type communication (MTC).

[0094] The terminal of the present application can be an on-board module, on-board module, on-board component, on-board chip, on-board unit (OBU) or telematics box (T-BOX) built into the vehicle as one or more components or units. The vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip, on-board unit or T-BOX. The terminal can also be a whole vehicle device. Therefore, the present application can be applied to the Internet of Vehicles, such as vehicle to everything (V2X), long-term evolution vehicle (LTE-V), vehicle to vehicle (V2V), etc.

[0095] It is understandable that in some scenarios, the roles of RAN nodes and terminals are relative. For example, a helicopter or drone, which is usually configured as a terminal, can also be configured as a mobile base station, and the device that accesses the RAN via the helicopter or drone is configured as a terminal.

[0096] It is understood that the communication system 1000 shown in Figure 1 is for illustrative purposes only and is not intended to limit the technical solutions of this application. Those skilled in the art will appreciate that, in a specific implementation, the communication system 1000 may further include other devices, and the number of RAN nodes and terminals may be determined based on specific needs and is not limited.

[0097] Optionally, each network element or device (such as a RAN node or terminal, etc.) in Figure 1 of the present application can also be referred to as a communication device, which can be a general device or a dedicated device. This application does not make specific limitations on this.

This application does not impose specific limitations on this. It is understood that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (such as a cloud platform).

[0099] In specific implementation, each network element or device (such as a RAN node or terminal, etc.) in Figure 1 of the present application can adopt the composition structure shown in Figure 3, or include the components shown in Figure 3.

The memory provided in this application may generally be non-volatile. Optionally, the memory 303 stores a program 307 (sometimes also referred to as code or instruction), and the program 307 can be executed on the processor 301 so that the communication device 30 executes the method described in the following method embodiment.

For example, the AI ​​module may be a near-real-time RIC or a non-real-time RIC.

[0103] Optionally, data may be stored in the processor 301 and / or the memory 303. The processor 301 and the memory 303 may be provided separately or integrated together.

[0104] Optionally, the communication device 30 may further include a transceiver 302 and / or an antenna 304.

[0105] It is understandable that the composition structure shown in Figure 3 does not constitute a limitation on the communication device. In addition to the components shown in Figure 3, the communication device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0106] The method provided by the present application will be described below with reference to the accompanying drawings. Each network element in the following embodiment may include the components shown in FIG3 , which will not be described in detail.

[0107] It can be understood that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in specific implementations, and the present application does not make any specific limitations on this.

[0108] It is understood that in this application, " / " can indicate that the objects associated with each other are in an "or" relationship, for example, A / B can mean A or B; "and / or" can be used to describe that there are three relationships between the associated objects, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In addition, expressions similar to "at least one of A, B and C" or "at least one of A, B or C" are usually used to indicate any of the following: A exists alone; B exists alone; C exists alone; A and B exist at the same time; A and C exist at the same time; B and C exist at the same time; A, B and C exist at the same time. The above uses A, B and C as an example to illustrate the optional items of the item. When there are more elements in the expression, the meaning of the expression can be obtained according to the above rules.

[0109] In order to facilitate the description of the technical solutions of the present application, in the present application, words such as "first" and "second" may be used to distinguish between technical features with the same or similar functions. The words such as "first" and "second" do not limit the quantity and execution order, and the words such as "first" and "second" do not necessarily limit them to be different. In the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or design. The use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0110] It is understood that the "embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, the various embodiments in the entire specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It is understood that in the various embodiments of the present application, the size of the sequence number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the present application.

[0111] It can be understood that in this application, "when...", "in the case of...", "if" and "if" all mean that corresponding processing will be taken under certain objective circumstances, and do not limit the time, nor do they require judgment actions when implementing them, nor do they mean that there are other limitations.

[0112] The term "simultaneously" in this application may be understood as at the same time point, within a period of time, or within the same cycle.

[0113] In this application, "condition" can be replaced with "event." For example, "first condition" in the following embodiments can be replaced with "first event." Furthermore, in this application, "performing an action when a condition is met" can also be understood as "performing an action when an event is met." For example, if the first condition is met, the terminal sends a first measurement report to the first network node, which can be understood as the terminal sending the first measurement report to the first network node when the first event is met.

[0114] In this application, "greater than or equal to" can be replaced by "greater than" or "equal to"; "less than or equal to" can be replaced by "less than" or "equal to".

[0115] It is understood that some optional features in this application may, in certain scenarios, be implemented independently of other features, such as the solution on which they are currently based, to solve corresponding technical problems and achieve corresponding effects. They may also be combined with other features in certain scenarios as needed. Accordingly, the devices provided in this application may also implement these features or functions accordingly, which will not be described in detail here.

[0116] It is understandable that the same step or steps or technical features with the same function in different embodiments of the present application can be referenced to each other.

[0117] It is understood that in the present application, a RAN node (such as the first RAN node, the second RAN node, the CU, the first DU, or the second DU in the following embodiments) and / or a terminal may perform some or all of the steps in the present application. These steps are merely examples, and the present application may also perform other steps or variations of various steps. In addition, the steps may be performed in a different order than presented in the present application, and it is possible that not all of the steps in the present application need to be performed.

[0118] It is understandable that the methods provided below in this application use a RAN node (such as the first RAN node, the second RAN node, the CU, the first DU, or the second DU in the following embodiments) and a terminal as examples of the execution entities of the interaction diagram to illustrate the method, but this application does not limit the execution entities of the interaction diagram. For example, the RAN node in the methods provided in the following embodiments of this application may also be a chip, a chip system, or a processor that supports the RAN node to implement the method, or may be a logical node, a logical module, or software that can implement all or part of the RAN node functions; the terminal in the methods provided below in this application may also be a chip, a chip system, or a processor that supports the terminal to implement the method, or may be a logical node, a logical module, or software that can implement all or part of the terminal functions.

[0119] As shown in FIG4 , a method for reporting a measurement report provided by the present application may include the following steps:

[0120] S401: A terminal sends a measurement report to a first RAN node. Correspondingly, the first RAN node receives the measurement report from the terminal.

[0121] The first RAN node can be any RAN node in the communication system 1000 shown in Figure 1, and the terminal is any terminal in the communication system 1000 that is communicatively connected to the first RAN node. The area covered by the first RAN node can be divided into multiple cells, and the terminal communicates with the first RAN node through one of the cells (which can be referred to as the terminal's serving cell). The following uses an example in which the multiple cells include cell 1 and cell 2, where cell 1 is the terminal's serving cell and cell 2 is a neighboring cell of cell 1, to illustrate the method provided in this application.

[0122] In one possible design, the measurement report includes the terminal's measurement result of the neighboring cell of cell 1, and the measurement result may be an L3 measurement result. For example, the measurement report includes the signal quality of cell 2 measured by the terminal. It will be understood that if the multiple cells also include cell 3, the measurement report may also include the signal quality of cell 3 measured by the terminal. Exemplarily, the signal quality in this application may refer to signal received power, such as reference signal received power (RSRP), or to signal received quality, such as reference signal received quality (RSRQ), without limitation.

[0123] S402: The first RAN node determines to initiate LTM configuration according to the measurement report.

[0124] Exemplarily, taking the case where the measurement report includes the signal quality of cell 2 measured by the terminal, if the signal quality of cell 2 measured by the terminal is greater than or equal to a threshold, the first RAN node determines to initiate LTM configuration for cell 2. For example, the first RAN node may determine a first reporting configuration and a first resource configuration.

[0125] The first report configuration includes information about the first condition. The first condition is a condition for the signal quality of the measurement signal. Optionally, the first report configuration also includes identification information of the first report configuration. The first resource configuration is associated with the first condition. The first resource configuration is used to configure M measurement signals of cell 2. The M measurement signals can be used by the terminal to measure the signal quality of cell 2, where M is a positive integer. Cell 2 is a candidate target cell for LTM handover. In this application, the candidate target cell can also be replaced by a candidate cell or an alternative cell, etc.

[0126] Optionally, the M measurement signals are signals of the same type. For example, the M measurement signals are M synchronization signal blocks (SSBs). In this case, the first resource configuration may include identification information of each of the M SSBs, such as an index of each SSB. For another example, the M measurement signals are M channel state information reference signals (CSI-RSs). In this case, the first resource configuration includes information of M CSI-RSs, which is used to indicate the time-frequency resources occupied by each CSI-RS.

[0127] It is understandable that in order to associate the M measurement signals (or the first resource configuration) with the first condition (or the first reporting configuration), an identifier, such as a first identifier, can be assigned to the M measurement signals (or the first resource configuration), and both the first reporting configuration and the first resource configuration include the identifier. Subsequently, the terminal receives the first reporting configuration and the first resource configuration, recognizes that the identifiers included in the two are the same, and determines that the first condition (or the first reporting configuration) is for the M measurement signals (or the first resource configuration).

[0128] In the present application, the first condition may be used by the terminal to determine whether to report measurement results for some or all of the M measurement signals.

[0129] In one possible design, the first condition includes at least one of the following: the difference between the quality of the measurement signal of cell 2 and the quality of the measurement signal of cell 1 is greater than or equal to the first threshold value; the quality of the measurement signal of cell 2 is greater than or equal to the second threshold value; the quality of the measurement signal of cell 1 is less than or equal to the third threshold value.

[0130] It can be understood that in order to indicate any of the above-mentioned first conditions to the terminal, the information of the first condition may include the corresponding threshold value. For example, if the first condition includes that the difference between the quality of the measurement signal of cell 2 and the quality of the measurement signal of cell 1 is greater than or equal to the first threshold value, the information of the first condition includes the first threshold value; if the first condition includes that the difference between the quality of the measurement signal of cell 2 and the quality of the measurement signal of cell 1 is greater than or equal to the first threshold value, and the quality of the measurement signal of cell 2 is greater than or equal to the second threshold value, the information of the first condition includes the first threshold value and the second threshold value; if the first condition includes that the difference between the quality of the measurement signal of cell 2 and the quality of the measurement signal of cell 1 is greater than or equal to the first threshold value, the quality of the measurement signal of cell 2 is greater than or equal to the second threshold value, and the quality of the measurement signal of cell 1 is less than or equal to the third threshold value, the information of the first condition includes the first threshold value, the second threshold value and the third threshold value.

[0131] It is understandable that the quality of the measurement signal of cell 2 can be the best signal quality among the M measurement signals, or the signal quality of any one of the M measurement signals, or the worst signal quality among the M measurement signals. The measurement signal of cell 1 can be the best signal quality among the measurement signals of cell 1, or the signal quality of any one of the measurement signals of cell 1, or the worst signal quality among the measurement signals of cell 1. The first condition is described below using Examples 1 to 5 as examples. It should be understood that Examples 1 to 5 are merely examples of the first condition. In specific applications, the first condition can also be other forms of conditions without limitation.

[0132] Example 1, the first condition includes that the difference between the quality of the measurement signal of cell 2 (for example, the best signal quality among M measurement signals, or the signal quality of any one of the M measurement signals, or the worst signal quality among the M measurement signals) and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1) is greater than or equal to the threshold value 1.

[0133] Example 2, the first condition includes that the quality of the measurement signal of cell 2 (for example, the best signal quality among M measurement signals, or the signal quality of any one of the M measurement signals, or the worst signal quality among the M measurement signals) is greater than or equal to threshold value 2, and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1) is less than or equal to threshold value 3.

[0134] Example 3, the first condition includes that the difference between the quality of the measurement signal of cell 2 (for example, the best signal quality among the M measurement signals, or the signal quality of any one of the M measurement signals, or the worst signal quality among the M measurement signals) and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1) is greater than or equal to the threshold value 4, and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1, or the signal quality of any one of the measurement signals of cell 1, or the worst signal quality among the measurement signals of cell 1) is less than or equal to the threshold value 5.

[0135] Example 4, the first condition includes that the quality of the measurement signal of cell 2 (for example, the best signal quality among the M measurement signals, or the signal quality of any one of the M measurement signals, or the worst signal quality among the M measurement signals) is greater than or equal to the threshold value 6, the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1, or the signal quality of any one of the measurement signals of cell 1, or the worst signal quality of the measurement signal of cell 1) is less than or equal to the threshold value 7, and the quality of the measurement signal of cell 2 (for example, the best signal quality among the M measurement signals) is greater than or equal to the threshold value 8.

[0136] Example 5, the first condition includes that the difference between the quality of the measurement signal of cell 2 (for example, the best signal quality among the M measurement signals) and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1) is greater than or equal to the threshold value 9, and the measurement signal of cell 1 (for example, the best signal quality among the measurement signals of cell 1) is less than or equal to the threshold value 10.

[0137] In addition to indicating the first condition through a threshold value, the information about the first condition may also indicate the first condition through an identifier of the corresponding condition. For example, assuming that the first conditions shown in Examples 1 to 5 correspond to identifiers 1 to 5, respectively, then when the information about the first condition includes identifier 1, the first condition is the condition shown in Example 1, and when the information about the first condition includes identifier 3, the first condition is the condition shown in Example 3.

[0138] Optionally, the first reporting configuration may also indicate that the reporting type of the measurement report of the following S405 is event reporting, so that the terminal determines that the measurement report for all or part of the M measurement signals can be reported based on event triggering, such as triggering the reporting of the measurement report for all or part of the M measurement signals when the first condition is met.

[0139] In specific applications, in addition to event reporting, measurement report reporting types also include periodic reporting, semi-static reporting, and aperiodic reporting. If the reporting type is periodic reporting, the terminal can periodically report measurement reports. If the reporting type is semi-static reporting, the terminal periodically reports measurement reports within a certain time period. If the reporting type is aperiodic reporting, the terminal aperiodically reports measurement reports.

[0140] In one possible design, the first reporting configuration may indicate the reporting type of the measurement report by carrying an identifier of the corresponding reporting type, or may indicate the reporting type of the measurement report by means of a bitmap.

[0141] For example, taking the identifier of event reporting as "sj", the identifier of periodic reporting as "zq", the identifier of semi-static reporting as "bjt", and the identifier of non-periodic reporting as "fzq" as an example, if the first reporting configuration includes "sj", it indicates that the reporting type of the measurement report of S405 is event reporting; if the first reporting configuration includes "zq", it indicates that the reporting type of the measurement report of S405 is periodic reporting; if the first reporting configuration includes "bjt", it indicates that the reporting type of the measurement report of S405 is semi-static reporting; if the first reporting configuration includes "fzq", it indicates that the reporting type of the measurement report of S405 is non-periodic reporting. In summary, in order to indicate that the reporting type of the measurement report of S405 is event reporting, in this example, the first reporting configuration includes "sj".

[0142] Exemplarily, the first report configuration includes 4 bits of indication information, and each of the 4 bits corresponds to a reporting type. For example, when the value of the indication information is "1000", it indicates that the reporting type of the measurement report of S405 is event reporting; when the value of the indication information is "0100", it indicates that the reporting type of the measurement report of S405 is periodic reporting; when the value of the indication information is "0010", it indicates that the reporting type of the measurement report of S405 is semi-static reporting; when the value of the indication information is "0001", it indicates that the reporting type of the measurement report of S405 is non-periodic reporting. In summary, in order to indicate that the reporting type of the measurement report of S405 is event reporting, in this example, the value of the indication information included in the first report configuration is "1000".

[0143] It is understandable that if the measurement report of S401 also includes the signal quality of cell 3 measured by the terminal, and the signal quality meets certain conditions, for example, the signal quality is greater than or equal to a certain threshold, the first RAN node may further determine to initiate the LTM configuration of cell 3. For example, the first RAN node may further determine a second reporting configuration and a second resource configuration.

[0144] Among them, the second resource configuration is used to configure P measurement signals of cell 3. The P measurement signals can be used by the terminal to measure the signal quality of cell 3, where P is a positive integer. Cell 3 is a candidate target cell for LTM switching. The second report configuration can indicate the reporting type of the measurement report for all or part of the P measurement signals, and / or the second report configuration may include information of the second condition. The second condition is used by the terminal to determine whether to report the measurement results for all or part of the P measurement signals. It can be understood that the introduction of the P measurement signals can refer to the above description of the M measurement signals, the introduction of the second condition can refer to the above description of the corresponding first condition, and the information of the second condition can refer to the above description of the information of the first condition, which will not be repeated.

[0145] Optionally, the first RAN node may further determine information about measurement signals other than the M measurement signals and the P measurement signals. For example, the first RAN node determines a third resource configuration. The third resource configuration is used to configure R measurement signals, where R is a positive integer. The R measurement signals may be R measurement signals for cell 1, R measurement signals for cell 2, R measurement signals for cell 3, and so on. It will be appreciated that information about the R measurement signals may also be included in the first resource configuration or the second resource configuration, without limitation.

[0146] Optionally, the first RAN node may further determine a third reporting configuration associated with the R measurement signals. For an introduction to the third reporting configuration, reference may be made to the above description of the second reporting configuration.

[0147] S403: The first RAN node sends an RRC reconfiguration message to the terminal. Correspondingly, the terminal receives the RRC reconfiguration message from the first RAN node.

[0148] In one possible design, the RRC reconfiguration message includes a first reporting configuration and a first resource configuration. Optionally, the RRC reconfiguration message also includes at least one of the following: a second resource configuration, a second reporting configuration, a third resource configuration, or a third reporting configuration. It should be understood that the above information may also be sent to the terminal via other messages without limitation.

[0149] It can be understood that the first resource configuration is associated with the first reporting configuration, the second resource configuration is associated with the second reporting configuration, and the third resource configuration is associated with the third reporting configuration. Taking the example of M measurement signals being M SSBs, P measurement signals being P CSI-RSs, and R measurement signals being R SSBs of cell 2, with the third reporting configuration including information on the third condition, the above association relationship can be shown in Figure 5. Specifically, the M SSBs of cell 2 are associated with the first condition. Therefore, when the first condition is met, the terminal can report a measurement report that includes measurement results for all or part of the M SSBs. The P CSI-RSs of cell 3 are associated with the second condition. Therefore, when the second condition is met, the terminal can report a measurement report that includes measurement results for all or part of the P CSI-RSs. The R SSBs of cell 2 are associated with the third condition. Therefore, when the third condition is met, the terminal can report a measurement report that includes measurement results for all or part of the R SSBs.

[0150] Optionally, the RRC reconfiguration message also includes first indication information. The first indication information may be used to indicate reporting of measurement results different from M measurement signals, or reporting of measurement results different from P measurement signals, or reporting of measurement results different from R measurement signals. Optionally, the first indication information may also indicate conditions for reporting the above measurement results. It will be understood that the first indication information is located in different fields of the RRC reconfiguration message and has different functions.

[0151] As an example, if the first reporting configuration includes first indication information, it indicates that the scope of the first indication information is the first reporting configuration, i.e., the first indication information indicates reporting of measurement results different from the M measurement signals. For example, in addition to reporting measurement results for all or part of the M measurement signals, the terminal can also report measurement results for all or part of the P measurement signals. In other words, even if the reporting conditions for the measurement results of the P measurement signals are not met, such as if the reporting period for the measurement results has not expired, the terminal can still report the measurement results. Of course, the terminal can also report measurement results for all or part of the R measurement signals. In this way, the first RAN node can determine the cell to be handed over for the terminal based not only on the measurement results of the M measurement signals, but also on measurement results different from the M measurement signals. In other words, when determining the cell to be handed over for the terminal, the first RAN node can have more options, so that the terminal can be handed over to a cell with better signal quality to provide better service for the terminal. Taking the example of a terminal reporting measurement results for all or part of M measurement signals (referred to as measurement result A), and measurement results for all or part of R measurement signals (referred to as measurement result B), assuming that measurement result B is better than measurement result A, although the reporting period of measurement result B is reached, because the terminal reports both measurement result A and measurement result B to the first RAN node based on the first indication information, the first RAN node can instruct the terminal to switch to the cell where the R measurement signals are located. In addition, if the M measurement signals correspond to wide beams and the R measurement signals correspond to narrow beams, the terminal can also directly switch to the narrow beam, thereby improving transmission efficiency. For details, please refer to the description corresponding to Figure 7 below.

[0152] As another example, if the second reporting configuration includes the first indication information, it indicates that the scope of the first indication information is the second reporting configuration, that is, the first indication information indicates reporting of measurement results different from the P measurement signals. For example, in addition to reporting measurement results for all or part of the P measurement signals, the terminal may also report measurement results for all or part of the M measurement signals and / or measurement results for all or part of the R measurement signals. This allows the first RAN node to have more options when determining a cell to be handed over for the terminal, facilitates handover of the terminal to a cell with better signal quality, and improves transmission efficiency.

[0153] As another example, if the third reporting configuration includes the first indication information, it indicates that the scope of the first indication information is the third reporting configuration, that is, the first indication information indicates reporting of measurement results different from the R measurement signals. For example, in addition to reporting measurement results for all or part of the R measurement signals, the terminal may also report measurement results for all or part of the M measurement signals and / or measurement results for all or part of the P measurement signals. This allows the first RAN node to have more options when determining a cell to be handed over for the terminal, thereby facilitating handover of the terminal to a cell with better signal quality and improving transmission efficiency.

[0154] As another example, the RRC reconfiguration message includes first indication information, a first reporting configuration, a second reporting configuration, and a third reporting configuration, but the first indication is not included in the first reporting configuration, the second reporting configuration, and the third reporting configuration, indicating that the scope of the first indication information is the first reporting configuration, the second reporting configuration, and the third reporting configuration. In other words, in addition to reporting measurement results for all or part of the M measurement signals, the terminal also reports measurement results different from the M measurement signals. Similarly, in addition to reporting measurement results for all or part of the P measurement signals, the terminal also reports measurement results different from the P measurement signals. In addition to reporting measurement results for all or part of the R measurement signals, the terminal also reports measurement results different from the R measurement signals.

[0155] Optionally, in response to the RRC reconfiguration message, the terminal may send an RRC reconfiguration complete message to the first RAN node. After receiving the RRC reconfiguration complete message, the first RAN node may determine that the terminal configuration completes the content configured in the RRC reconfiguration message.

[0156] S404: The terminal performs measurement on all or part of the M measurement signals of cell 2.

[0157] It is understandable that if the RRC reconfiguration message includes the second reporting configuration and the second resource configuration, the terminal further measures all or part of the P measurement signals. Similarly, if the RRC reconfiguration message includes the third reporting configuration and the third resource configuration, the terminal further measures all or part of the R measurement signals.

[0158] S405: When the first condition is met, the terminal sends a measurement report to the first RAN node. Correspondingly, the first RAN node receives the measurement report sent by the terminal when the first condition is met.

[0159] The measurement report includes measurement results of N measurement signals, where the M measurement signals include N measurement signals, where N is an integer greater than 0 and less than or equal to M. The measurement result is an L1 measurement result. Exemplarily, the N measurement signals may be measurement signals that can be measured by the terminal among the M measurement signals, or N measurement signals with the best signal quality among the M measurement signals, without limitation.

[0160] In one possible implementation, when the measurement signal with the best signal quality among the M measurement signals meets the first condition, the terminal sends the measurement report to the first RAN node; or when any one measurement signal among the M measurement signals meets the first condition, the terminal sends the measurement report to the first RAN node.

[0161] It is understandable that the N measurement signals may include the measurement signal that triggers the first condition, or may not include the measurement signal that triggers the first condition, without limitation. Taking the M measurement signals including measurement signals 1 to 3 as an example, assuming that the signal quality of measurement signal 1 measured by the terminal is the best and the signal quality of measurement signal 3 is the worst, and the first condition is that the difference between the signal quality of measurement signal 3 and the signal quality of the serving cell is greater than the first threshold value, then when the signal quality of measurement signal 3 meets the first condition, the terminal can send the above-mentioned measurement report to the first RAN node. The measurement report can include the measurement result of measurement signal 1, the measurement result of measurement signal 2, and the measurement result of measurement signal 3, or the measurement report includes the measurement result of measurement signal 1 and the measurement result of measurement signal 2, but does not include the measurement result of measurement signal 3.

[0162] Optionally, the measurement report further includes at least one of the following: identification information of cell 2, identification information of the N measurement signals, identification information of the measurement report, or an identifier of the first resource configuration (such as the first identifier described above). The identification information of the measurement report and the identifier of the first resource configuration may be associated with cell 2, so that the second RAN node determines that the measurement report is for cell 2.

[0163] Optionally, the measurement report also includes measurement results of Q measurement signals. The Q measurement signals are different from the M measurement signals. For example, the R measurement signals include the Q measurement signals, or the P measurement signals include the Q measurement signals. In other words, the Q measurement signals may be measurement signals in cell 2 that are different from the M measurement signals, for example, the Q measurement signals are Q SSBs of cell 2, the M measurement signals are M CSI-RSs of cell 2, or the Q measurement signals are SSBs with indices of 0 to (Q-1) of cell 2, and the M measurement signals are SSBs with indices of T to (T+M-1) of cell 2, where T is greater than (Q-1) or greater than 0. Alternatively, the Q measurement signals may be measurement signals of cells other than cell 2. It should be understood that when the M measurement signals are M SSBs, the indexes of the M SSBs may be discontinuous. Similarly, when the Q measurement signals are Q SSBs, the indexes of the Q SSBs may be discontinuous.

[0164] In a possible implementation, in response to the first indication information, the measurement report further includes measurement results of the Q measurement signals. Alternatively, based on protocol provisions, the measurement report further includes measurement results of the Q measurement signals.

[0165] Optionally, if the RRC reconfiguration message also includes a second reporting configuration, the terminal may send measurement reports for all or some of the P measurement signals according to the second reporting configuration. For example, if the second condition is met, the terminal sends measurement results of S measurement signals to the first RAN node. The P measurement signals include S measurement signals, where S is an integer greater than 0 and less than or equal to P. Similarly, if the RRC reconfiguration message also includes a third reporting configuration, the terminal may send measurement reports for all or some of the R measurement signals according to the third reporting configuration.

[0166] S406: The first RAN node sends a handover command to the terminal. Correspondingly, the terminal receives the handover command from the first RAN node.

[0167] In one possible implementation, in response to the measurement report in S405, the first RAN node sends a handover command (cell switch command) to the terminal. The handover command instructs handover to cell 2. The handover command may be carried in a layer 2 (L2) message, such as a medium access control control element (MAC-CE).

[0168] Exemplarily, when the measurement results of the N measurement signals meet certain conditions, the first RAN node sends a handover command to the terminal. Taking the measurement results shown in Figure 6 as an example, the terminal is currently communicating with the first RAN node via signal 601. Because the signal quality of signal 604 measured by the terminal is significantly greater than the signal quality of signal 601 and the signal quality of signal 602, the first RAN node may determine to handover the terminal to cell 2 and send a handover command to the terminal.

[0169] Optionally, different measurement signals among the above-mentioned M measurement signals correspond to different beams, so that the first RAN node completes beam alignment during the handover process, and there is no need to perform beam alignment again after the handover is completed, which can reduce the delay of beam alignment. For example, the first RAN node also indicates the first measurement signal to the terminal, for example, by carrying identification information of the first measurement signal or transmission configuration indicator (TCI) state (TCI state) identification information through a handover command, so that the terminal directly switches to the beam where the first measurement signal is located when performing cell handover. The above-mentioned identification information is associated with the first measurement signal. The above-mentioned N measurement signals include the first measurement signal. Taking the measurement results shown in Figure 6 as an example, since the signal quality of signal 604 is greater than the signal quality of signal 603, the first measurement signal can be signal 604. Therefore, the terminal can directly switch to the beam where signal 604 is located during the cell handover process to provide the terminal with better service quality and reduce the delay of beam alignment.

[0170] It is understandable that if the signal quality of signal 603 and the signal quality of signal 604 are both lower than the signal quality of signal 602, the first RAN node may also determine not to perform cell switching, but to switch the terminal from the beam where signal 601 is located to the beam where signal 602 is located.

[0171] In the present application, the first measurement signal may not be a measurement signal among the N measurement signals, but a measurement signal among the Q measurement signals mentioned above. Taking the beam shown in Figure 7 as an example, cell 1 includes beam 701 and beam 702, and the beam where the terminal is currently located is beam 701. The measurement report of S405 includes the signal quality of the measurement signals corresponding to beams 703 to 706 respectively. Among them, the N measurement signals include the measurement signal corresponding to beam 704 and the measurement signal corresponding to beam 705, and the Q measurement signals include the measurement signal corresponding to beam 703 and the measurement signal corresponding to beam 706. Beam 701, beam 702, beam 704 and beam 705 are wide beams, such as beams corresponding to SSB, and beam 703 and beam 706 are narrow beams, such as beams corresponding to CSI-RS. When the first RAN node determines to switch the terminal to cell 2, it can directly switch the terminal to a narrow beam, such as beam 703 or beam 706, to improve transmission efficiency. It can be understood that in this example, the beam where the first measurement signal is located is beam 703 or beam 706.

[0172] S407: The terminal switches to cell 2.

[0173] It can be understood that after receiving the handover command, the terminal can be handed over to cell 2. If the first RAN node further indicates a first measurement signal, the terminal can communicate with cell 2 based on the first measurement signal.

[0174] In the present application, after the terminal completes random access, the first RAN node may use the TCI state of cell 2 to schedule the terminal for uplink data transmission. Alternatively, the first RAN node may directly use the TCI state of cell 2 to schedule the terminal for uplink data transmission. For example, if, before S407, the first RAN node has not sent an uplink synchronization configuration, such as a timing advance (TA) configuration, to the terminal, the first RAN node may use the TCI state of cell 2 to schedule the terminal for uplink data transmission after the terminal completes random access; if, before S407, the first RAN node has already sent an uplink synchronization configuration, such as a TA configuration, to the terminal, the first RAN node may directly use the TCI state of cell 2 to schedule the terminal for uplink data transmission.

[0175] It can be understood that the actions of the first RAN node or terminal in the above steps can be executed by the processor 301 in the communication device 30 shown in Figure 3 calling the application code stored in the memory 303, and this application does not impose any limitation on this.

[0176] Based on the method shown in Figure 4, the first RAN node can configure the terminal to report measurement reports based on events. Accordingly, the terminal can report measurement reports when the trigger conditions of the event are met, without having to report measurement reports periodically. On the one hand, this can reduce resource overhead. On the other hand, when the trigger conditions of the event are met, it indicates that the signal quality of the serving cell is poor, and the terminal is more likely to perform a cell handover, so the terminal can report the measurement report. When the trigger conditions of the event are not met, it indicates that the signal quality of the serving cell is good, and the terminal does not need to perform a cell handover, so there is no need for the terminal to report the measurement report. Therefore, the above method can reduce signaling overhead.

[0177] The above description of the method provided by this application uses the example of a terminal handover from one cell of a first RAN node to another cell. In specific applications, the terminal may also perform inter-site handover, such as handover from a cell of a first RAN node to a cell of a second RAN node. The following describes the method provided by this application in conjunction with the inter-site handover scenario.

[0178] As shown in FIG8 , another method for reporting a measurement report provided by the present application may include the following steps:

[0179] S801: A terminal sends a measurement report to a first RAN node. Correspondingly, the first RAN node receives the measurement report from the terminal.

[0180] The first RAN node may be any RAN node in the communication system 1000 shown in FIG1 , and the terminal may be any terminal in the communication system 1000 that is communicatively connected to the first RAN node. The area covered by the first RAN node may be divided into multiple cells, and the terminal communicates with the first RAN node through one of the cells, such as cell 1.

[0181] In one possible design, the measurement report includes the terminal's measurement results of neighboring cells of cell 1, which may be L3 measurement results. The method provided in this application is described below using an example where the neighboring cells of cell 1 include a cell of a second RAN node, such as cell 2. The second RAN node may be a RAN node different from the first RAN node in the communication system 1000 shown in FIG1 . In this case, the measurement report includes the signal quality of cell 2 measured by the terminal.

[0182] It is understandable that, in addition to including the signal quality of cell 2 measured by the terminal, the measurement report may also include the signal quality of cells other than cell 1 and cell 2, such as cell 3. Cell 3 may be a cell of a second RAN node, or a cell of a RAN node other than the first and second RAN nodes. This application is described using the example of cell 3 being also a cell of the second RAN node.

[0183] S802: The first RAN node determines to initiate LTM configuration according to the measurement report.

[0184] For example, taking the measurement report including the signal quality of cell 2 measured by the terminal as an example, if the signal quality of cell 2 measured by the terminal is greater than or equal to a threshold, the first RAN node determines to initiate LTM configuration of cell 2. For example, the first RAN node may request the second RAN node to configure cell 2 for handover.

[0185] For example, taking the example of a measurement report including the signal quality of cell 2 measured by the terminal and the signal quality of cell 3 measured by the terminal, if the signal quality of cell 2 measured by the terminal is greater than or equal to a threshold, the first RAN node determines to initiate LTM configuration for cell 2. For example, the first RAN node may request the second RAN node for the configuration of cell 2 for handover. If the signal quality of cell 3 measured by the terminal is greater than or equal to a threshold, the first RAN node determines to initiate LTM configuration for cell 3. For example, the first RAN node may request the second RAN node for the configuration of cell 3 for handover.

[0186] S803: The first RAN node sends a handover request message to the second RAN node. Correspondingly, the second RAN node receives the handover request message from the first RAN node.

[0187] It will be appreciated that if the first RAN node determines to initiate LTM configuration for cell 2 (hereinafter referred to as Scenario 1), the handover request message is used to request the configuration of cell 2 for handover, with respect to LTM. For example, the handover request message includes identification information of cell 2 and an LTM indication. The LTM indication indicates that a handover is initiated with respect to LTM. Optionally, the handover request message also includes resource request information for cell 2, which is used to request resources of cell 2, which can be used by the terminal to measure the signal quality of cell 2.

[0188] It will be appreciated that if the first RAN node determines to initiate LTM configuration for cell 2 and cell 3 (hereinafter referred to as scenario 2), the handover request message is used to request the configuration of cell 2 and cell 3 for handover with respect to LTM. For example, the handover request message includes identification information for cell 2, identification information for cell 3, and an LTM indication. It will be appreciated that the handover request message may include two LTM indications, which respectively indicate the initiation of LTM handover for cell 2 and cell 3, or the handover request message may include one LTM indication, which indicates the initiation of LTM handover for both cell 2 and cell 3. Optionally, the handover request message also includes resource request information for cell 2 and cell 3. This resource request information is used to request resources for cell 2 and cell 3. The resources of cell 2 are used by the terminal to measure the signal quality of cell 2. The resources of cell 3 are used by the terminal to measure the signal quality of cell 3.

[0189] S804: The second RAN node sends a handover request acknowledgement message to the first RAN node. Correspondingly, the first RAN node receives the handover request acknowledgement message from the second RAN node.

[0190] It can be understood that for the above scenario 1 and scenario 2, the content included in the handover request confirmation message is different.

[0191] For scenario 1, the handover request confirmation message is used to confirm the LTM configuration of cell 2 provided for handover. For example, the handover request confirmation message includes a first resource configuration. The first resource configuration is used to configure M measurement signals for cell 2. For details, please refer to the corresponding description in the embodiment shown in Figure 4. The difference is that in the embodiment shown in Figure 4, cell 2 belongs to the first RAN node, while in the embodiment shown in Figure 8, cell 2 belongs to the second RAN node. Optionally, if the handover request message includes resource request information for cell 2, then in response to the resource request information, the handover request confirmation message includes the first resource configuration.

[0192] For scenario 2, the handover request confirmation message is used to confirm the LTM configuration of cell 2 and the LTM configuration of cell 3 provided for handover. For example, the handover request confirmation message includes a first resource configuration and a second resource configuration. The first resource configuration is used to configure M measurement signals of cell 2, and the second resource configuration is used to configure P measurement signals of cell 3. For details, please refer to the corresponding introduction in the embodiment shown in Figure 4. The difference is that in the embodiment shown in Figure 4, cell 2 and cell 3 belong to the first RAN node, and in the embodiment shown in Figure 8, cell 2 and cell 3 belong to the second RAN node. Optionally, if the handover request message includes resource request information of cell 2 and cell 3, then in response to the resource request information, the handover request confirmation message includes the first resource configuration and the second resource configuration.

[0193] Optionally, the handover request confirmation message may further include a resource configuration different from the first resource configuration and the second resource configuration, such as a third resource configuration. The third resource configuration is used to configure R measurement signals, where the R measurement signals may be R measurement signals for cell 2, or R measurement signals for cell 3, etc. It is understandable that information about the R measurement signals may also be included in the first resource configuration or the second resource configuration, without limitation.

[0194] S805: The first RAN node determines a first reporting configuration.

[0195] It is understood that for scenario 1, the first RAN node determines a first reporting configuration. The first reporting configuration is associated with the first resource configuration, and the first reporting configuration includes information about the first condition. For a detailed description of the first reporting configuration, please refer to the corresponding description in the embodiment shown in FIG4 .

[0196] As will be appreciated, for scenario 2, the first RAN node determines a first reporting configuration and a second reporting configuration. The first reporting configuration is associated with the first resource configuration and includes information about the first condition. The second reporting configuration is associated with the second resource configuration. Optionally, the second reporting configuration includes information about the second condition. For a detailed description of the first and second reporting configurations, please refer to the corresponding description in the embodiment shown in FIG4 .

[0197] It will be appreciated that if the handover request confirmation message includes the third resource configuration, the first RAN node may further determine a third reporting configuration. The third reporting configuration is associated with the third resource configuration. Optionally, if the handover request confirmation message does not include the third resource configuration, the first RAN node may determine the third resource configuration, where the third resource configuration is used to configure R measurement signals for cell 1. The first RAN node may further determine a third reporting configuration associated with the third resource configuration. For a description of the third resource configuration, the third reporting configuration, and the R measurement signals, please refer to the corresponding description of the embodiment shown in FIG.

[0198] S806: The first RAN node sends an RRC reconfiguration message to the terminal. Correspondingly, the terminal receives the RRC reconfiguration message from the first RAN node.

[0199] In one possible design, the RRC reconfiguration message includes a first reporting configuration and a first resource configuration. Optionally, the RRC reconfiguration message also includes at least one of the following: a second resource configuration, a second reporting configuration, a third resource configuration, a third reporting configuration, or first indication information. The process of S806 is similar to the process of S403 above, and reference may be made to the corresponding description in S403, which is not repeated here.

[0200] S807: The terminal performs measurement on all or part of the M measurement signals of cell 2.

[0201] S808: When the first condition is met, the terminal sends a measurement report to the first RAN node. Correspondingly, the first RAN node receives the measurement report sent by the terminal when the first condition is met.

[0202] S809: The first RAN node sends a handover command to the terminal. Correspondingly, the terminal receives the handover command from the first RAN node.

[0203] It can be understood that the specific process of S807 to S809 is similar to the specific process of S404 to S406. Please refer to the corresponding introduction of S404 to S406 above and no further details will be given.

[0204] S810: The first RAN node sends notification information to the second RAN node. Correspondingly, the second RAN node receives the notification information from the first RAN node.

[0205] The notification information is used to indicate that a handover command has been sent. The communication information may include identification information of the TCI state of cell 2 and second indication information. The second indication information is used to indicate access to cell 2 by random access (RA based LTM) or access to cell 2 by non-random access (RA-less LTM). For example, the second indication information includes 1 bit. When the value of the 1 bit is "0", it indicates access to cell 2 by non-random access. When the value of the 1 bit is "1", it indicates access to cell 2 by random access, and vice versa. Alternatively, if the second indication information includes the field "RACH-based LTM", the second indication information indicates access to cell 2 by random access. If the second indication information includes the field "RACH-less LTM", the second indication information indicates access to cell 2 by non-random access. The notification information may also include identification information of cell 2.

[0206] In one possible implementation, if, before S810, the first RAN node has sent an uplink synchronization configuration, such as a TA configuration, to the terminal, the second indication information indicates access to cell 2 without random access; if, before S810, the first RAN node has not sent an uplink synchronization configuration, such as a TA configuration, to the terminal, the second indication information indicates access to cell 2 through random access. The uplink synchronization configuration may be obtained by the first RAN node from the second RAN node and sent to the terminal.

[0207] It is understandable that the present application does not limit the execution order of S809 and S810. For example, S809 may be executed first and then S810, or S810 may be executed first and then S809, or S810 and S809 may be executed simultaneously without limitation.

[0208] S811: The terminal switches to cell 2.

[0209] It can be understood that after receiving the handover command, the terminal can be handed over to cell 2. If the first RAN node further indicates a first measurement signal, the terminal can communicate with cell 2 based on the first measurement signal.

[0210] It is understandable that if the second indication information indicates access to cell 2 in a random access manner, the second RAN node may use the TCI state of cell 2 to perform data transmission with the terminal after the terminal completes random access. If the second indication information indicates access to cell 2 in a non-random access manner, the second RAN node directly uses the TCI state of cell 2 to perform data transmission with the terminal.

[0211] Optionally, after the terminal is switched to cell 2, the first RAN node may release resources configured for the terminal.

[0212] It can be understood that the actions of the first RAN node or the second RAN node or the terminal in the above steps can be executed by the processor 301 in the communication device 30 shown in Figure 3 calling the application code stored in the memory 303, and this application does not impose any restrictions on this.

[0213] Based on the method shown in Figure 8, the first RAN node can request the second RAN node for the configuration of cell 2 for handover, based on LTM, and configure the terminal with a reporting configuration for event-based measurement reporting based on this configuration. This allows the terminal to report a measurement report when the event triggering conditions are met, without the need for periodic measurement reports. This reduces resource overhead. Furthermore, when the event triggering conditions are met, it indicates that the signal quality of the serving cell is poor, and the terminal is more likely to perform a cell handover, so the terminal can report a measurement report. However, when the event triggering conditions are not met, it indicates that the signal quality of the serving cell is good, and the terminal does not need to perform a cell handover, so there is no need for the terminal to report a measurement report. Therefore, the above method can reduce signaling overhead.

[0214] In addition to the method shown in FIG4 and the method shown in FIG8 , the method provided in this application can also be combined with the scenario where the CU and DU are separated, as described in detail below.

[0215] As shown in FIG9 , another method for reporting a measurement report provided by the present application may include the following steps:

[0216] S901: The terminal sends a measurement report to the first DU. Correspondingly, the first DU receives the measurement report from the terminal.

[0217] The first DU may be DU 1102 in Figure 2. The terminal is any terminal that is in communication with the first DU. The area covered by the first DU may be divided into at least one cell, and the terminal communicates with the first DU through one of the cells, such as cell 1.

[0218] In one possible design, the measurement report includes the terminal's measurement result of the neighboring cell of cell 1, and the measurement result may be an L3 measurement result. The method provided in this application is described below using a cell in which the neighboring cell of cell 1 includes a second DU, such as cell 2, as an example. The second DU and the first DU are connected to the same CU. For example, the second DU may be DU 1103 in Figure 2, and the CU may be CU 1101 in Figure 2. In this case, the measurement report includes the signal quality of cell 2 measured by the terminal.

[0219] It is understandable that, in addition to including the signal quality of cell 2 measured by the terminal, the measurement report may also include the signal quality of cells other than cell 1 and cell 2, such as cell 3. Cell 3 may be the cell of the second DU, or the cell of a DU other than the first DU and the second DU. This application is described using the example of cell 3 being the cell of the second DU.

[0220] S902: The first DU sends a measurement report to the CU. Correspondingly, the CU receives the measurement report from the first DU.

[0221] Exemplarily, the measurement report may be sent to the CU via an uplink (UL) RRC message transmission (UL RRC MESSAGE TRANSFER) message.

[0222] S903: The CU determines to initiate LTM configuration according to the measurement report.

[0223] For example, taking the measurement report including the signal quality of cell 2 measured by the terminal as an example, if the signal quality of cell 2 measured by the terminal is greater than or equal to a threshold, the CU determines to initiate the LTM configuration of cell 2. For example, the CU may request the second DU to configure cell 2 for handover.

[0224] For example, taking the case where the measurement report includes the signal quality of cell 2 measured by the terminal and the signal quality of cell 3 measured by the terminal, if the signal quality of cell 2 measured by the terminal is greater than or equal to a threshold, the CU determines to initiate the LTM configuration of cell 2. For example, the CU may request the second DU to configure cell 2 for handover. If the signal quality of cell 3 measured by the terminal is greater than or equal to a threshold, the CU determines to initiate the LTM configuration of cell 3. For example, the CU may request the second DU to configure cell 3 for handover.

[0225] S904: The CU sends a UE context setup request message to the second DU. Correspondingly, the second DU receives the UE context setup request message from the CU.

[0226] It is understandable that if the CU determines to initiate the LTM configuration of cell 2 (hereinafter referred to as scenario 3), the UE context establishment request message is used to request the configuration of cell 2 for handover for LTM. For example, the UE context establishment request message includes identification information of cell 2 and an LTM indication. The LTM indication is used to indicate the initiation of handover for LTM. Optionally, the UE context establishment request message also includes resource request information of cell 2, and the resource request information of cell 2 is used to request resources of cell 2, which can be used by the terminal to measure the signal quality of cell 2.

[0227] It can be understood that if the CU determines to initiate the LTM configuration of cell 2 and the LTM configuration of cell 3 (hereinafter referred to as scenario 4), the UE context establishment request message is used to request the configuration of cell 2 and the configuration of cell 3 for switching for LTM. For example, the UE context establishment request message includes the identification information of cell 2, the identification information of cell 3 and the LTM indication. It should be understood that the UE context establishment request message may include two LTM indications, which respectively indicate the initiation of LTM switching for cell 2 and the initiation of LTM switching for cell 3, or the UE context establishment request message includes one LTM indication, which initiates LTM switching for cell 2 and cell 3. Optionally, the UE context establishment request message also includes resource request information for cell 2 and cell 3. The resource request information is used to request the resources of cell 2 and cell 3. The resources of cell 2 are used by the terminal to measure the signal quality of cell 2. The resources of cell 3 are used by the terminal to measure the signal quality of cell 3.

[0228] S905: The second DU sends a UE context setup response message to the CU. Correspondingly, the CU receives the UE context setup response message from the second DU.

[0229] It can be understood that for the above scenario 3 and scenario 4, the content included in the UE context establishment response message is different.

[0230] For scenario 3, the UE context establishment response message includes a first resource configuration. The first resource configuration is used to configure M measurement signals for cell 2. For details, refer to the corresponding description in the embodiment shown in Figure 4 . The difference is that in the embodiment shown in Figure 4 , cell 2 belongs to the first RAN node, while in the embodiment shown in Figure 9 , cell 2 belongs to the second DU. Optionally, if the UE context establishment request message includes resource request information for cell 2, then in response to the resource request information, the UE context establishment response message includes the first resource configuration.

[0231] For scenario 4, the UE context setup response message includes a first resource configuration and a second resource configuration. The first resource configuration is used to configure M measurement signals for cell 2, and the second resource configuration is used to configure P measurement signals for cell 3. For details, please refer to the corresponding description in the embodiment shown in Figure 4. The difference is that in the embodiment shown in Figure 4, cells 2 and 3 belong to the first RAN node, while in the embodiment shown in Figure 9, cells 2 and 3 belong to the second DU. Optionally, if the UE context setup request message includes resource request information for cells 2 and 3, then in response to the resource request information, the UE context setup response message includes the first resource configuration and the second resource configuration.

[0232] Optionally, the UE context establishment response message may further include a resource configuration different from the first resource configuration and the second resource configuration, such as a third resource configuration. The third resource configuration is used to configure R measurement signals, where the R measurement signals may be R measurement signals of cell 2, or R measurement signals of cell 3, etc. It is understandable that information about the R measurement signals may also be included in the first resource configuration or the second resource configuration, without limitation.

[0233] S906: The CU sends a UE context modification request message to the first DU. Correspondingly, the first DU receives the UE context modification request message from the CU.

[0234] It will be appreciated that the UE Context Modification Request message includes different content for Scenario 3 and Scenario 4. For example, for Scenario 3, the UE Context Modification Request message includes the first resource configuration. For Scenario 4, the UE Context Modification Request message includes the first resource configuration and the second resource configuration. Optionally, the UE Context Modification Request message may also include a third resource configuration.

[0235] S907: The first DU determines a first reporting configuration.

[0236] It is understandable that for scenario 3, the first DU determines the first reporting configuration. The first reporting configuration is associated with the first resource configuration, and the first reporting configuration includes information about the first condition. Specifically, the description of the first reporting configuration can refer to the corresponding introduction in the embodiment shown in Figure 4.

[0237] As can be understood, for scenario 4, the first DU determines a first reporting configuration and a second reporting configuration. The first reporting configuration is associated with the first resource configuration and includes information about the first condition. The second reporting configuration is associated with the second resource configuration. Optionally, the second reporting configuration includes information about the second condition. For a detailed description of the first reporting configuration and the second reporting configuration, please refer to the corresponding descriptions in the embodiment shown in FIG4 .

[0238] It will be appreciated that if the UE context modification request message includes the third resource configuration, the first DU may also determine a third reporting configuration. The third reporting configuration is associated with the third resource configuration. Optionally, if the UE context modification request message does not include the third resource configuration, the first DU may determine the third resource configuration, where the third resource configuration is used to configure R measurement signals for cell 1. The first DU may also determine a third reporting configuration associated with the third resource configuration. For a description of the third resource configuration, the third reporting configuration, and the R measurement signals, please refer to the corresponding description of the embodiment shown in FIG.

[0239] It is understandable that, in specific applications, the first, second, and third reporting configurations may be determined by the CU rather than the first DU. In other words, after S905, the CU may determine the corresponding reporting configuration and send it to the terminal via the first DU.

[0240] S908: The first DU sends a UE context modification response message to the CU. Correspondingly, the CU receives the UE context modification response message from the first DU.

[0241] It can be understood that for scenario 3, the UE context modification response message includes the first reporting configuration and the first resource configuration. For scenario 4, the UE context modification response message includes the first reporting configuration, the first resource configuration, the second reporting configuration, and the second resource configuration.

[0242] Optionally, the UE context modification response message also includes a third reporting configuration and a third resource configuration.

[0243] S909: The CU sends an RRC reconfiguration message to the terminal via the first DU. Correspondingly, the terminal receives the RRC reconfiguration message from the CU via the first DU.

[0244] It can be understood that the CU can transparently transmit the RRC reconfiguration message to the terminal through the first DU.

[0245] In one possible design, the RRC reconfiguration message includes a first reporting configuration and a first resource configuration. Optionally, the RRC reconfiguration message also includes at least one of the following: a second resource configuration, a second reporting configuration, a third resource configuration, a third reporting configuration, or the first indication information.

[0246] Optionally, in response to the RRC reconfiguration message, the terminal may send an RRC reconfiguration complete message to the CU via the first DU. After receiving the RRC reconfiguration complete message, the CU may determine that the terminal configuration completes the content configured in the RRC reconfiguration message.

[0247] It is understandable that for the rest of the introduction of S909, reference can be made to the corresponding description in S403, which will not be repeated here.

[0248] S910: The terminal performs measurement on all or part of the M measurement signals of cell 2.

[0249] S911: When a first condition is met, the terminal sends a measurement report to the first DU. Correspondingly, the first DU receives the measurement report sent by the terminal when the first condition is met.

[0250] S912: The first DU sends a handover command to the terminal. Correspondingly, the terminal receives the handover command from the first DU.

[0251] It can be understood that the specific process of S910 to S912 is similar to the specific process of S404 to S406. Please refer to the corresponding introduction of S404 to S406 above and no further details will be given.

[0252] S913: The first DU sends notification information to the CU. Correspondingly, the CU receives the notification information from the first DU.

[0253] The notification information is used to indicate that the handover command has been sent. The communication information may include identification information of the TCI state of cell 2 and the second indication information. For details, please refer to the corresponding introduction in the embodiment shown in Figure 8.

[0254] Optionally, the notification information is carried in a cell switch notify message.

[0255] S914: The CU sends notification information to the second DU. Correspondingly, the second DU receives the notification information from the CU.

[0256] Optionally, the notification information is carried in a cell switching notification message.

[0257] It can be understood that the present application does not limit the execution order of S912 and S913~S914. For example, S912 can be executed first and then S913~S914, or S913~S914 can be executed first and then S912, or S912 and S913~S914 can be executed at the same time without limitation.

[0258] S915: The terminal switches to cell 2.

[0259] It can be understood that after receiving the handover command, the terminal can be handed over to cell 2. If the first DU also indicates a first measurement signal, the terminal can communicate with cell 2 based on the first measurement signal.

[0260] It can be understood that if the second indication information indicates access to cell 2 in a random access manner, the second DU can use the TCI state of cell 2 to transmit data with the terminal after the terminal completes random access. If the second indication information indicates access to cell 2 without random access, the second DU directly uses the TCI state of cell 2 to transmit data with the terminal.

[0261] Optionally, after the terminal switches to cell 2, the first DU may release resources configured for the terminal.

[0262] It can be understood that the actions of the first DU or second DU or CU or terminal in the above steps can be executed by the processor 301 in the communication device 30 shown in Figure 3 calling the application code stored in the memory 303, and this application does not impose any restrictions on this.

[0263] Based on the method shown in Figure 9, the CU can request the second DU for the configuration of cell 2 for handover based on LTM, and send the configuration to the first DU, so that the first DU can configure the terminal with a report configuration based on event-reported measurement reports based on the configuration, so that the terminal reports the measurement report when the triggering conditions of the event are met, without the need to report the measurement report periodically. On the one hand, it can reduce resource overhead. On the other hand, when the triggering conditions of the event are met, it indicates that the signal quality of the serving cell is poor and the terminal is more likely to perform cell handover, so the terminal can report the measurement report. When the triggering conditions of the event are not met, it indicates that the signal quality of the serving cell is good and the terminal does not need to perform cell handover, so there is no need for the terminal to report the measurement report. Therefore, the above method can reduce signaling overhead.

[0264] The embodiments shown in FIG4 , FIG8 , and FIG9 respectively introduce the method provided in the present application by taking the intra-station handover scenario, the inter-station handover scenario, and the CU / DU separation scenario as examples. However, the method provided in the present application is not limited to the above-mentioned scenarios. Based on the design idea of ​​the method provided in the present application, the method provided in the present application can be applied to other handover scenarios. For example, in any handover scenario, in addition to configuring at least one group of resources for measurement for the terminal (for example, the above-mentioned M measurement signals can be regarded as a group of resources), the network node can also configure corresponding conditions for reporting measurement reports for each group of resources, which are related to the signal quality of the measurement signal. Therefore, the terminal can determine whether to report the measurement report based on the signal quality of the measurement signal, rather than periodically reporting the measurement report, to reduce resource overhead. In order to better understand the above-mentioned design ideas, the method provided in the present application is introduced below by taking the method shown in FIG10 as an example.

[0265] As shown in FIG10 , another method for reporting a measurement report provided by the present application may include the following steps:

[0266] S1001: A first network node sends first configuration information and second configuration information to a terminal. Correspondingly, the terminal receives the first configuration information and the second configuration information from the first network node.

[0267] The information of the first configuration is associated with the information of the second configuration. Exemplarily, the first configuration is a CSI resource configuration, and the second configuration is a CSI report configuration. The CSI resource may include a CSI-RS or an SSB.

[0268] In one possible implementation, a first network node determines information about a first configuration and information about a second configuration associated with the first configuration, and sends the first and second configuration information to a terminal. Alternatively, a second network node managing a first cell sends the first configuration information to the first network node. Accordingly, the first network node receives the first configuration information from the second network node. Thereafter, the first network node determines information about a second configuration associated with the first configuration, and sends the first and second configuration information to the terminal. It should be understood that the first and second configuration information can be sent to the terminal in a single message or in separate messages, without limitation.

[0269] In the present application, the first configuration information includes information about M measurement signals of a first cell, where the M measurement signals can be used by a terminal to measure the signal quality of the first cell, where M is a positive integer. The first cell is a candidate target cell for mobility handover triggered by layer 1 or layer 2. Optionally, the M measurement signals are signals of the same type. For example, the M measurement signals are M SSBs, or the M measurement signals are M CSI-RSs.

[0270] In the present application, the information of the second configuration includes information of the first condition, and the first condition is associated with the first configuration (such as the configuration of M measurement signals of the first cell). The first condition is a condition for the signal quality of the measurement signal, which can be used by the terminal to determine whether to report the measurement results for some or all of the M measurement signals. Optionally, the information of the second configuration is also used to indicate that the reporting type of the first measurement report in S1002 is event reporting, so that the terminal determines to report the first measurement report based on the event, such as reporting the first measurement report when the first condition is met.

[0271] In one possible design, the first condition includes at least one of the following: the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value; the quality of the measurement signal of the first cell is greater than or equal to the second threshold value; the quality of the measurement signal of the serving cell is less than or equal to the third threshold value.

[0272] Optionally, in the present application, the quality of the measurement signal can be understood as the quality of the beam (such as the quality of the beam in which the measurement signal is located or the quality of the beam associated with the measurement signal), rather than the quality of the cell.

[0273] In one possible design, the information of the first condition includes at least one of a first threshold value, a second threshold value, or a third threshold value. That is, in order to indicate any of the above-mentioned first conditions to the terminal, the information of the first condition may include the corresponding threshold value. For example, if the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, then the information of the first condition includes the first threshold value; if the first condition includes that the difference between the quality of the measurement signal of the first cell and the quality of the measurement signal of the serving cell is greater than or equal to the first threshold value, and the quality of the measurement signal of the first cell is greater than or equal to the second threshold value, then the information of the first condition includes the first threshold value and the second threshold value.

[0274] The following introduces the first network node, the second network node, the terminal, the first cell, the serving cell, the first configuration information, the second configuration information, the first condition and the information of the first condition in combination with the embodiment shown in Figure 4, the embodiment shown in Figure 8 and the embodiment shown in Figure 9 respectively.

[0275] For example, using the embodiment shown in Figure 4 as an example, the first network node is the first RAN node in the embodiment shown in Figure 4 , the terminal is the terminal in the embodiment shown in Figure 4 , and the embodiment shown in Figure 4 does not involve a second network node. The first cell is cell 2 in the embodiment shown in Figure 4 , and the serving cell is cell 1 in the embodiment shown in Figure 4 . The first configuration information and the second configuration information can be carried in the RRC reconfiguration message in S403 . For example, the first configuration information includes the first resource configuration, and the second configuration information includes the first reporting configuration. The first condition is the first condition in the embodiment shown in Figure 4 , and the information of the first condition is the information of the first condition in the embodiment shown in Figure 4 .

[0276] For example, taking the embodiment shown in FIG8 as an example, the first network node is the first RAN node in the embodiment shown in FIG8 , the second network node is the second RAN node in the embodiment shown in FIG8 , and the terminal is the terminal in the embodiment shown in FIG8 . The first cell is cell 2 in the embodiment shown in FIG8 , and the serving cell is cell 1 in the embodiment shown in FIG8 . The first configuration information and the second configuration information can be carried in the RRC reconfiguration message in S806 . For example, the first configuration information includes the first resource configuration, and the second configuration information includes the first reporting configuration. The first condition is the first condition in the embodiment shown in FIG8 , and the information of the first condition is the information of the first condition in the embodiment shown in FIG8 .

[0277] For example, taking the embodiment shown in Figure 9 as an example, the first network node is the first DU or CU in the embodiment shown in Figure 9, the second network node is the second DU in the embodiment shown in Figure 9, and the terminal is the terminal in the embodiment shown in Figure 9. The first cell is cell 2 in the embodiment shown in Figure 9, and the serving cell is cell 1 in the embodiment shown in Figure 9. The first configuration information and the second configuration information can be carried in the RRC reconfiguration message in S909. For example, the first configuration information includes the first resource configuration, and the second configuration information includes the first reporting configuration. The first condition is the first condition in the embodiment shown in Figure 9, and the information of the first condition is the information of the first condition in the embodiment shown in Figure 9.

[0278] S1002: When a first condition is met, the terminal sends a first measurement report to the first network node. Correspondingly, the first network node receives the first measurement report sent by the terminal when the first condition is met.

[0279] In the present application, the first measurement report includes measurement results of N measurement signals, where the measurement results may indicate, for example, the quality of the N measurement signals, so that the first network node determines whether the terminal performs cell handover based on the measurement results. The M measurement signals include N measurement signals, where N is an integer greater than 0 and less than or equal to M.

[0280] Optionally, the first measurement report also includes measurement results of Q measurement signals, which may indicate the quality of the Q measurement signals. The Q measurement signals are configured using information from a third configuration, which is different from the first configuration. For example, the first network node may send first indication information to the terminal. In response to the first indication information, the first measurement report also includes measurement results of the Q measurement signals. Through the above solution, the first network node can determine whether the terminal should perform cell handover based not only on the measurement results of the N measurement signals, but also on the measurement results of the Q measurement signals. It is understandable that, for the terminal, the N measurement signals are not necessarily the measurement signals with the best signal quality. Therefore, the first network node can combine the measurement results of the N measurement signals with the measurement results of the Q measurement signals to determine a measurement signal with better signal quality for the terminal, so that the terminal can switch to the beam containing the measurement signal, thereby ensuring the communication quality of the terminal. In addition, if the beam containing each of the Q measurement signals is a thin beam, such as a CSI-RS beam, the terminal does not need to perform beam alignment when switching to the thin beam, which can reduce the delay of beam alignment.

[0281] Optionally, the first indication information may be included in the first configuration, or in other configurations, without limitation. For an introduction to the first indication information, reference may be made to the corresponding descriptions in the embodiments shown in FIG4 , FIG8 , and FIG9 , and no further details will be given.

[0282] In a possible implementation, the Q measurement signals are all different from the M measurement signals, or are partially different. For details, reference may be made to the corresponding descriptions in the embodiments shown in FIG4 , FIG8 , and FIG9 .

[0283] A possible design that satisfies the first condition includes at least one of the following: the difference between the best signal quality among the M measurement signals and the best signal quality among the measurement signals of the serving cell is greater than or equal to the first threshold value; the best signal quality among the M measurement signals is greater than or equal to the second threshold value; the best signal quality among the measurement signals of the serving cell is less than or equal to the third threshold value.

[0284] It is understandable that the best signal quality among the M measurement signals may be replaced by the signal quality of any one of the M measurement signals, or by the worst signal quality among the M measurement signals. And / or, the best signal quality among the measurement signals of the serving cell may be replaced by the signal quality of any one of the measurement signals of the serving cell, or by the worst signal quality among the measurement signals of the serving cell.

[0285] Exemplarily, satisfying the first condition may mean that the difference between the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) and the best signal quality among the measurement signals of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is greater than or equal to the threshold value 1.

[0286] Exemplarily, satisfying the first condition may mean that: the best signal quality among the M measurement signals (or the signal quality of any one measurement signal among the M measurement signals) is greater than or equal to threshold value 2, and the best signal quality among the measurement signals of the serving cell is less than or equal to threshold value 3.

[0287] Exemplarily, satisfying the first condition may mean that: the difference between the best signal quality among the M measurement signals (or the signal quality of any one measurement signal among the M measurement signals) and the best signal quality among the measurement signals of the serving cell is greater than or equal to the threshold value 4, and the best signal quality among the measurement signals of the serving cell (or the signal quality of any one measurement signal among the measurement signals of the serving cell) is less than or equal to the threshold value 5.

[0288] Exemplarily, satisfying the first condition may mean that: the best signal quality among the M measurement signals (or the signal quality of any one of the M measurement signals) is greater than or equal to the threshold value 6, and the best signal quality among the measurement signals of the serving cell (or the signal quality of any one of the measurement signals of the serving cell) is less than or equal to the threshold value 7, and the best signal quality among the M measurement signals is greater than or equal to the threshold value 8.

[0289] Exemplarily, satisfying the first condition may mean that the difference between the best signal quality among the M measurement signals and the best signal quality among the measurement signals of the serving cell is greater than or equal to the threshold value 9, and the best signal quality among the measurement signals of the serving cell is less than or equal to the threshold value 10.

[0290] The first measurement report, the first indication information, and the Q measurement signals are described below in conjunction with the embodiment shown in FIG. 4 , the embodiment shown in FIG. 8 , and the embodiment shown in FIG. 9 .

[0291] Exemplarily, taking the embodiment shown in FIG4 as an example, the first measurement report is the measurement report in S405 of the embodiment shown in FIG4 , the first indication information is the first indication information in S405 , and the Q measurement signals are the Q measurement signals in S405 .

[0292] Exemplarily, taking the embodiment shown in FIG8 as an example, the first measurement report is the measurement report in S808 of the embodiment shown in FIG8 , the first indication information is the first indication information in S808 , and the Q measurement signals are the Q measurement signals in S808 .

[0293] Exemplarily, taking the embodiment shown in FIG9 as an example, the first measurement report is the measurement report in S912 of the embodiment shown in FIG9 , the first indication information is the first indication information in S912, and the Q measurement signals are the Q measurement signals in S912.

[0294] Based on the method shown in FIG10 , the first network node can configure a first condition for measuring signal quality for the terminal. Therefore, the terminal does not need to periodically report measurement reports to the first network node. Instead, the terminal sends measurement reports to the first network node only when the first condition is met. Therefore, the above method can reduce resource overhead.

[0295] Optionally, in a possible implementation of the method shown in FIG10 , in response to the first measurement report, the first network node may send a handover command to the terminal so that the terminal performs cell handover. For example, the method shown in FIG10 may further include the following steps:

[0296] S1003: In response to the first measurement report, the first network node sends a handover command to the terminal. Correspondingly, the terminal receives the handover command from the first network node.

[0297] The handover command indicates handover to the first cell. The handover command also indicates the first measurement signal. Specifically, the handover command includes identification information of the TCI state of the first cell, the TCI state is associated with the first measurement signal, and the identification information of the TCI state may indicate the first measurement signal. The N measurement signals include the first measurement signal, or the Q measurement signals include the first measurement signal.

[0298] S1004: In response to the handover command, the terminal switches to the first cell.

[0299] S1005: The terminal communicates with the first cell based on the first measurement signal.

[0300] It can be understood that the specific processes of the above S1003~S1005 can refer to the corresponding descriptions in S406~S407 in the embodiment shown in Figure 4, or refer to the corresponding descriptions in S809 and S811 in the embodiment shown in Figure 8, or refer to the corresponding descriptions in S912 and S915 in the embodiment shown in Figure 9.

[0301] Optionally, the first network node also sends notification information to the second network node. Accordingly, the second network node receives the notification information from the first network node. The notification information is used to indicate that a handover command has been sent. The notification information includes identification information of the TCI state of the first cell and second indication information. The second indication information is used to indicate access to the first cell through random access (RA based) or access to the first cell through RACH-less. For example, if the second indication information includes the field "RACH-based LTM", the second indication information indicates access to the first cell through random access; if the second indication information includes the field "RACH-less LTM", the second indication information indicates access to the first cell through random access.

[0302] It can be understood that in response to the second indication information used to indicate access to the first cell by random access, the second network node uses the TCI state of the first cell indicated by the notification message to communicate with the terminal (for example, perform physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH) transmission with the terminal) after the random access is completed (for example, receiving hybrid automatic repeat request (HARQ) feedback for message 4 for random access).

[0303] It can be understood that in response to the second indication information for indicating access to the first cell in a non-random access manner, the second network node, after receiving the notification message, uses the TCI state of the first cell indicated by the notification message to communicate with the terminal (for example, perform PDCCH or PDSCH transmission with the terminal). Accessing the first cell in a non-random access (RACH-less) manner should be understood as accessing the first cell through the PUSCH without sending a random access preamble.

[0304] In this way, the second network node can know when to use the TCI state indicated in the notification information, thereby avoiding resource waste. For details of the above process, please refer to the corresponding description in S810 of the embodiment shown in Figure 8, or refer to the corresponding description in S913-S914 of the embodiment shown in Figure 9.

[0305] It is understandable that the actions of the first network node or the second network node or the terminal in the above steps can be executed by the processor 301 in the communication device 30 shown in Figure 3 calling the application code stored in the memory 303, and this application does not impose any limitation on this.
