[0066] In some possible implementations, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can be deployed on the water surface (such as ships, etc.); can be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0067] In some possible implementations, the terminal device may include a device with wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip and may also include other discrete devices.

[0068] In some possible implementations, the terminal device described in the embodiments of the present application may be a chip, a chip module, a device, a unit, etc., without specific limitation.

[0069] 2. Network Equipment

[0070] A network device may be a device with transceiver functions and may be used to communicate with a terminal device.

[0071] In some possible implementations, the network device may be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side.

[0072] In some possible implementations, the network device may include a base station (BS) in a communication system or a device deployed in a radio access network (RAN) for providing wireless communication functions, that is, the network device may include a device in the RAN.

[0073] For example, the devices in the RAN may include an evolved node B (eNB or eNodeB) in an LTE communication system, a next generation evolved node B (ng-eNB) in an NR communication system, a next generation node B (gNB) in an NR communication system, a master node (MN) in a dual-connection architecture, a second node or secondary node (SN) in a dual-connection architecture, etc., without specific limitation.

[0074] In some possible implementations, the network device may include a device in a core network (CN).

[0075] For example, the equipment in the CN may include an access and mobility management function (AMF), a user plane function (UPF), a session management function (SMF), etc.

[0076] In some possible implementations, the network device may also be an access point (AP) in a WLAN, a relay station, a communication device in a future evolved PLMN network, a communication device in an NTN network, and the like.

[0077] In some possible implementations, the network device may include a device that provides wireless communication functionality for the terminal device, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, or may include other discrete devices.

[0078] In some possible implementations, the network device may communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0079] In some possible implementations, the network device may include an independent node to implement the functions of the above-mentioned base station, or may include two or more independent nodes to implement the functions of the above-mentioned base station. For example, the network device includes a centralized unit (CU) and a distributed unit (DU), such as a gNB-CU and a gNB-DU. Furthermore, in other embodiments of the present application, the network device may also include an active antenna unit (AAU). The CU implements part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, RF processing, and related functions of the active antenna. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this network deployment, high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent jointly by the DU and AAU. It is understood that network devices may include at least one of the CU, DU, and AAU. Furthermore, the CU may be classified as a RAN device, or as a core network device, without specific limitation.

Among them, multi-site coherent cooperative transmission can be joint coherent transmission of multiple sites, or different data belonging to the same physical downlink shared channel (PDSCH) are sent from different sites to the terminal device, or multiple sites are virtualized into one site for transmission. Names with the same meaning specified in other standards also apply to this application, that is, this application does not limit the names of these parameters. The sites in multi-site coherent cooperative transmission can be remote radio heads (RRHs), transmission and reception points (TRPs), network devices, etc., and there is no specific limitation on this.

[0081] In some possible implementations, the network device may be any one of the multiple sites that perform incoherent collaborative transmission with the terminal device, or other sites outside the multiple sites, or other network devices that perform network communication with the terminal device, and there is no specific limitation on this.

[0085] To facilitate understanding of the embodiments of the present application, the relevant names or terms involved in the present application are explained below.

[0086] 1. Community

[0087] In a dual connectivity (DC) or carrier aggregation (CA) scenario, a terminal device is configured with two cell groups, one of which is a master cell group (MCG) and the other is a secondary cell group (SCG). A master cell group (MCG) refers to a cell group associated with a master eNB (MeNB), including a primary cell (PCell) and zero or at least one secondary cell (SCell). A secondary cell group (SCG) refers to a cell group associated with a secondary eNB (SeNB), including a primary secondary cell (PSCell) and zero or at least one secondary cell.

[0088] Among them, DC may include: Evolved Universal Terrestrial Radio Access NR dual connectivity (E-UTRA NR dual connectivity, ENDC), NR E-UTRA Dual Connectivity (NR E-UTRA Dual Connectivity, NEDC), NRDC, etc. ENDC refers to the terminal device accessing the NR network through a 4G access network device, with the 4G access network device serving as the primary base station and the 5G access network device serving as the secondary base station. NEDC refers to the 5G access network device serving as the primary base station and the 4G access network device serving as the secondary base station. NRDC refers to two 5G access network devices, one 5G access network device serving as the primary base station and the other 5G access network device serving as the secondary base station. For example, in the example shown in Figure 1, network device 1 can be the primary base station, and network device 2 can be the secondary base station.

[0089] It is understood that the primary cell refers to the cell that establishes a radio resource control (RRC) connection with the terminal device. The primary cell is responsible for providing security-related parameters and is configured with physical uplink control channel (PUCCH) resources. The primary and secondary cells refer to the secondary cells in the secondary cell group that are configured with PUCCH resources. Compared with the primary cell, the secondary cell can provide additional radio resources.

[0090] It should be understood that when a cell provides services to a terminal device, the cell may be referred to as a serving cell, such as a primary serving cell (i.e., the primary cell is the serving cell), a primary and secondary serving cell (i.e., the primary and secondary cells are the serving cells), or a secondary serving cell (i.e., the secondary cell is the serving cell).

[0091] In the DC scenario, one cell in the primary cell group and the secondary cell group may serve as the service cell for the terminal device, or multiple cells may serve as the service cells for the terminal device.

[0092] 2. Signal Quality

[0093] The signal quality of a cell mentioned in this application is the result of measuring the signal quality or signal energy based on the wireless signal, such as one or more of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), and signal to interference plus noise ratio (SINR).

[0094] Among them, the wireless signal may include, for example: synchronization signal block (synchronization signal and physical broadcast channel block, SSB), sounding reference signal (sounding reference signal, SRS), tracking reference signal (tracking reference signal, TRS), phase tracking reference signal (phase tracking reference signal, PTRS), channel state information reference signal (channel state information reference signal, CSI-RS), demodulation reference signal (demodulation reference signal, DMRS) or positioning reference signal (positioning reference signal, PRS), etc., which is not limited in this application.

[0095] 3. Signal Quality Prediction Function

[0096] The signal quality prediction function mentioned in this application refers to the use of AI technology to predict signal quality. For example, the terminal device can deploy an AI model (also known as an AI algorithm) that is used to predict signal quality.

[0097] Among them, AI models are a type of mathematical algorithm model that uses machine learning to solve practical problems. AI models can include a large number of parameters and calculation formulas (or calculation rules). The parameters in the AI ​​model are numerical values ​​that can be obtained by training the AI ​​model using a training data set. Exemplarily, the AI ​​model is used to predict signal quality, and the training data set may include, for example, one or more signal qualities.

[0098] 4. RLF failure prediction function

[0099] The RLF failure prediction function mentioned in this application refers to the use of AI technology to predict the occurrence of RLF failure. For example, the terminal device can deploy an AI model that is used to predict the occurrence of RLF failure.

[0100] 5. Cell Handover Failure (HO Failure) Prediction Function

[0101] The cell handover failure prediction function mentioned in this application refers to the use of AI technology to predict cell handover failure. For example, the terminal device can deploy an AI model that is used to predict cell handover failure.

[0102] In communication scenarios, AI technology is gradually being introduced on the terminal side, which leads to excessive energy consumption on the terminal side. Based on this, the present application provides an embodiment shown in Figure 2, Figure 3 or Figure 4 to solve this problem. Among them, the execution subject of the method shown in Figure 2, Figure 3 or Figure 4 can be a terminal device and a network device. Alternatively, the execution subject of the method shown in Figure 2, Figure 3 or Figure 4 can be a chip in the terminal device and the network device. Figure 2, Figure 3 or Figure 4 is illustrated by taking the terminal device and the network device as the execution subject of the method as an example.

[0103] Referring to Figure 2 , which is a flow chart of a communication method provided by an embodiment of the present application, the method includes the following steps 201 to 202 .

[0104] 201. A terminal device obtains first indication information, where the first indication information is used to indicate first threshold data for enabling a prediction function.

[0105] For example, the terminal device receives first indication information from the network device.

[0106] Optionally, the first indication information may be carried in a radio resource control (RRC) message, downlink control information (DCI) or a media access control-control element (MAC CE), which is not limited in this application.

[0107] 202. The terminal device starts a prediction function based on the first threshold data.

[0108] In this application, the prediction function may be a signal quality prediction function, an RLF failure prediction function, or a cell handover failure prediction function. Step 202 is described below in combination with these cases. Specifically:

[0109] 1. The prediction function is the signal quality prediction function

[0110] 1. The first threshold data includes first signal quality threshold data. The terminal device can obtain the first signal quality data measured by the terminal device and enable the signal quality prediction function based on the size relationship between the first signal quality threshold data and the first signal quality data.

[0111] 1.1. The first signal quality threshold data includes a signal quality threshold value H11 of the serving cell. The first signal quality data includes the signal quality measured by the terminal device for the serving cell. When the signal quality measured by the terminal device for the serving cell is less than or equal to H11, the terminal device enables the signal quality prediction function. The present application does not impose any restrictions on the value of H11.

[0112] As an example, the first signal quality data can be understood as: the signal quality of the serving cell measured one or more times by the terminal device in time period 1. In this case, it can be understood that: when the signal quality of the serving cell measured one or more times by the terminal device in time period 1 is less than or equal to H11, the terminal device turns on the signal quality prediction function. In this application, the length of time period 1 is not limited.

[0113] As another example, the first signal quality data can be understood as: the average value, minimum value, maximum value or median of the signal quality of the service cell measured multiple times by the terminal device in time period 1, or the weighted average value of the signal quality of the service cell measured multiple times. In this case, it can be understood that: when the average value, minimum value, maximum value or median or weighted average value of the signal quality of the service cell measured multiple times by the terminal device in time period 1 is less than or equal to H11, the terminal device turns on the signal quality prediction function.

[0114] As another example, the first signal quality data can be understood as: the signal quality of the service cell measured for the first time or the last time by the terminal device in time period 1. In this case, it can be understood that: when the signal quality of the service cell measured for the first time or the last time by the terminal device in time period 1 is less than or equal to H11, the terminal device turns on the signal quality prediction function.

[0115] Optionally, the number of times the terminal device measures the serving cell in time period 1 may be one or more times. The present application does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 1.

[0116] 1.2. The first signal quality threshold data includes a threshold value H12 of the difference between the signal quality of the neighboring cell and the signal quality of the primary cell. The first signal quality data includes the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the primary cell. When the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the primary cell is greater than or equal to H12, the terminal device enables the signal quality prediction function. The present application does not limit the size of H12.

[0117] As an example, the first signal quality data can be understood as: the signal quality of the neighboring cell measured K times by the terminal device in time period 1 and the signal quality of the primary cell measured K times, where K is an integer greater than or equal to 1. In this case, turning on the signal quality prediction function in this manner can be understood as:

[0118] For example, if the difference between the signal quality of the neighboring cell measured K times by the terminal device in time period 1 and the signal quality of the corresponding main cell is greater than or equal to H12, the terminal device turns on the signal quality prediction function. Specifically, assuming that the signal quality of the neighboring cell measured three times by the terminal device in time period 1 is signal quality 1 to signal quality 3, and the signal quality of the main cell measured three times by the terminal device in time period 1 is signal quality A to signal quality C, signal quality 1 is greater than signal quality A, and the difference between signal quality 1 and signal quality A is greater than or equal to H12; signal quality 2 is greater than signal quality B, and the difference between signal quality 2 and signal quality B is greater than or equal to H12, and so on, which will not be elaborated here.

[0119] For example, if the difference between the average value of the signal quality of the neighboring cell measured K times by the terminal device in time period 1 and the average value of the signal quality of the primary cell measured K times by the terminal device in time period 1 is greater than or equal to H12, the terminal device enables the signal quality prediction function. The average value here can be replaced by: minimum value, maximum value, weighted average value, or median.

[0120] For example, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 and the signal quality of the primary cell measured for the first time by the terminal device in time period 1 is greater than or equal to H12, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 and the signal quality of the primary cell measured for the last time by the terminal device in time period 1 is greater than or equal to H12, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 and the signal quality of the primary cell measured for the last time by the terminal device in time period 1 is greater than or equal to H12, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 and the signal quality of the primary cell measured for the first time by the terminal device in time period 1 is greater than or equal to H12, the terminal device turns on the signal quality prediction function.

[0121] It should be noted that the above lists some possible implementation methods of 'enabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0122] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 1 may be the same as or different from the number of times the terminal device measures the signal quality of the primary cell in time period 1, and this application does not limit this.

[0123] Optionally, the terminal device may measure the neighboring cell once or more times in time period 1, and the terminal device may measure the primary cell once or more times in time period 1. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 1.

[0124] 1.3. The first signal quality threshold data includes a signal quality threshold value H13 of a neighboring cell. The first signal quality data includes the signal quality of the neighboring cell measured by the terminal device. When the signal quality measured by the terminal device for the neighboring cell is greater than or equal to H13, the terminal device enables the signal quality prediction function. The present application does not impose any restrictions on the value of H13.

[0125] As an example, the first signal quality data can be understood as: the signal quality of the neighboring area measured once or multiple times by the terminal device in time period 1. In this case, it can be understood that: when the signal quality of the neighboring area measured once or multiple times by the terminal device in time period 1 is greater than or equal to H13, the signal quality prediction function is turned on.

[0126] As another example, the first signal quality data can be understood as: the average value, minimum value, maximum value, weighted average value or median of the signal quality of the neighboring area measured multiple times by the terminal device in time period 1. In this case, it can be understood that: when the average value, minimum value, maximum value, weighted average value or median of the signal quality of the neighboring area measured multiple times by the terminal device in time period 1 is greater than or equal to H13, the signal quality prediction function is turned on.

In this case, it can be understood that: when the signal quality of the neighboring area measured for the first time or the last time by the terminal device in time period 1 is greater than or equal to H13, the signal quality prediction function is turned on.

[0128] The number of times the terminal device measures the neighboring cell in time period 1 may be one or more times. The present application does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 1.

[0129] 1.4. The first signal quality threshold data includes a signal quality threshold value H14 of the primary cell and a signal quality threshold value H15 of the neighboring cell. The first signal quality data includes the signal quality measured by the terminal device for the primary cell and the signal quality measured by the terminal device for the neighboring cell. When the signal quality measured by the terminal device for the primary cell is less than or equal to H14 and the signal quality measured by the terminal device for the neighboring cell is greater than or equal to H15, the terminal device enables the signal quality prediction function. This application does not limit the values ​​of H14 and H15.

[0130] As an example, the first signal quality data can be understood as: the signal quality of the neighboring cell measured S times by the terminal device in time period 1 and the signal quality of the primary cell measured S times, where S is an integer greater than or equal to 1. In this case, turning on the signal quality prediction function in this manner can be understood as:

[0131] For example, if the signal quality of the main cell measured S times by the terminal device in time period 1 is less than or equal to H14, and the signal quality of the neighboring cell measured S times by the terminal device in time period 1 is greater than or equal to H15, the terminal device turns on the signal quality prediction function.

[0132] For example, if the average value (which can be replaced by: minimum value, maximum value, weighted average value or median) of the signal quality of the main cell measured S times by the terminal device in time period 1 is less than or equal to H14, and the average value (which can be replaced by: minimum value, maximum value, weighted average value or median) of the signal quality of the neighboring cell measured S times by the terminal device in time period 1 is greater than or equal to H15, the terminal device turns on the signal quality prediction function.

[0133] For example, if the signal quality of the primary cell measured for the first time by the terminal device in time period 1 is less than or equal to the threshold value H14, and the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 is greater than or equal to the threshold value H15, the terminal device turns on the signal quality prediction function. Or, if the signal quality of the primary cell measured for the last time by the terminal device in time period 1 is less than or equal to the threshold value H14, and the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 is greater than or equal to the threshold value H15, the terminal device turns on the signal quality prediction function. Or, if the signal quality of the primary cell measured for the first time by the terminal device in time period 1 is less than or equal to the threshold value H14, and the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 is greater than or equal to the threshold value H15, the terminal device turns on the signal quality prediction function. Or, if the signal quality of the primary cell measured for the last time by the terminal device in time period 1 is less than or equal to the threshold value H14, and the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 is greater than or equal to the threshold value H15, the terminal device turns on the signal quality prediction function.

[0134] It should be noted that the above lists some possible implementation methods of 'enabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0135] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 1 may be the same as or different from the number of times the terminal device measures the signal quality of the primary cell in time period 1, and this application does not limit this. Optionally, the number of times the terminal device measures the neighboring cell in time period 1 may be one or more times, and the number of times the terminal device measures the primary cell in time period 1 may be one or more times. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 1.

[0136] 1.5. The first signal quality threshold data includes a threshold value H16 of the difference between the signal quality of the neighboring cell and the signal quality of the secondary cell. The first signal quality data includes the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the secondary cell. When the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the secondary cell is greater than or equal to H16, the signal quality prediction function is enabled. The present application does not limit the size of H16.

[0137] As an example, the first signal quality data can be understood as: the signal quality of the neighboring cell measured X times and the signal quality of the secondary cell measured X times by the terminal device in time period 1, where X is an integer greater than or equal to 1. In this case, turning on the signal quality prediction function in this manner can be understood as:

[0138] For example, if the difference between the signal quality of the neighboring cell measured X times by the terminal device in time period 1 and the signal quality of the corresponding secondary cell is greater than or equal to the threshold value H16, the terminal device turns on the signal quality prediction function. Specifically, assuming that the signal quality of the neighboring cell measured three times by the terminal device in time period 1 is signal quality 1 to signal quality 3, and the signal quality of the secondary cell measured three times by the terminal device in time period 1 is signal quality A to signal quality C, signal quality 1 is greater than signal quality A, and the difference between signal quality 1 and signal quality A is greater than or equal to the threshold value H16; signal quality 2 is greater than signal quality B, and the difference between signal quality 2 and signal quality B is greater than or equal to the threshold value H16, and so on, it will not be repeated here.

[0139] For example, if the difference between the average value of the signal quality of the neighboring cell measured by the terminal device X times in time period 1 and the average value of the signal quality of the secondary cell measured by the terminal device X times in time period 1 is greater than or equal to threshold value H16, the terminal device enables the signal quality prediction function. The average value here can be replaced by: minimum value, maximum value, weighted average value, or median value.

[0140] For example, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 and the signal quality of the secondary cell measured for the first time by the terminal device in time period 1 is greater than or equal to the threshold value H16, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 and the signal quality of the secondary cell measured for the last time by the terminal device in time period 1 is greater than or equal to the threshold value H16, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 1 and the signal quality of the secondary cell measured for the last time by the terminal device in time period 1 is greater than or equal to the threshold value H16, the terminal device turns on the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 1 and the signal quality of the secondary cell measured for the first time by the terminal device in time period 1 is greater than or equal to the threshold value H16, the terminal device turns on the signal quality prediction function.

[0141] It should be noted that the above lists some possible implementation methods of 'enabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0142] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 1 may be the same as or different from the number of times the terminal device measures the signal quality of the secondary cell in time period 1, and this application does not limit this. Optionally, the number of times the terminal device measures the neighboring cell in time period 1 may be one or more times, and the number of times the terminal device measures the secondary cell in time period 1 may be one or more times. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 1.

[0143] It should be understood that the terminal device in the embodiment shown in FIG2 can be connected to one or more base stations, and this application does not limit the number of base stations to which the terminal can be connected simultaneously.

[0144] For example, any one or more of the above methods 1.1 to 1.5 may be applicable to scenarios where a terminal device is connected to one or more base stations. For example, in a DC or CA scenario, a terminal device may be connected to one or more base stations. In this case, the serving cell may include a cell in a primary cell group and / or a cell in a secondary cell group, and the primary cell may be a cell in the primary cell group. The secondary cell may be a cell in the secondary cell group, and this application does not impose any restrictions.

[0145] Exemplarily, in a DC or CA scenario, the service cell may include one or more of the following: a main cell in the main cell group of the terminal device (i.e., the service cell is the main service cell mentioned above), a secondary cell in the secondary cell group of the terminal device (i.e., the service cell is the secondary service cell mentioned above), a main and secondary cell in the secondary cell group of the terminal device (i.e., the service cell is the main and secondary service cell mentioned above), and a secondary cell in the main cell group of the terminal device.

[0146] For example, a serving cell is a primary cell of a terminal device. It should be understood that when a terminal device is configured with one serving cell, the serving cell may be referred to as the primary cell of the terminal device; when a terminal device is configured with multiple serving cells, one of the multiple serving cells may be referred to as the primary cell of the terminal device, and the other serving cells in the multiple serving cells may be referred to as secondary cells of the terminal device.

[0147] For example, a serving cell is a secondary cell of a terminal device. It should be understood that when a terminal device is configured with one serving cell, the serving cell may be referred to as the primary cell of the terminal device; when a terminal device is configured with multiple serving cells, one of the multiple serving cells may be referred to as the primary cell of the terminal device, and the other serving cells in the multiple serving cells may be referred to as secondary cells of the terminal device.

[0148] For example, the serving cells are the primary cell and the secondary cell of the terminal device. It should be understood that when the terminal device is configured with one serving cell, the serving cell can be referred to as the primary cell of the terminal device; when the terminal device is configured with multiple serving cells, one serving cell among the multiple serving cells can be referred to as the primary cell of the terminal device, and the other serving cells among the multiple serving cells can be referred to as the secondary cells of the terminal device.

[0149] Based on the above description, it can be understood that the application scenarios of this application are not limited to DC or CA scenarios, and can also be applied in other scenarios, such as non-DC and non-CA scenarios, where the terminal device is connected to a base station. In this case, the terminal device can use the above-mentioned method 1.1 and / or method 1.3 to enable the signal quality prediction function.

[0150] It should be understood that, regardless of the application scenario, the above-mentioned neighboring cells may include one or more of the same-frequency cells and different-frequency cells. The same-frequency cell means that the SSB used for measurement has the same center frequency (central frequency) and subcarrier spacing (SCS) as the cell-defining SSB of the serving cell. The different-frequency cell means that the SSB used for measurement has at least one different center frequency and SCS from the cell-defining SSB of the serving cell.

[0151] 2. The first threshold data includes first speed threshold data. The terminal device can obtain the first speed data measured by the terminal device and enable the signal quality prediction function based on the size relationship between the first speed threshold data and the first speed data.

[0152] 2.1. The first speed threshold data includes a speed threshold value V11. The first speed data includes the movement speed of the terminal device. When the movement speed of the terminal device is greater than or equal to V11, the terminal device starts the signal quality prediction function. This application does not limit the size of V11.

[0153] As an example, the movement speed of the terminal device may include the movement speed of the terminal device measured once or multiple times within the first time period. In this case, enabling the signal quality prediction function in this manner may be understood as:

[0154] For example, when the movement speed measured by the terminal device once or multiple times within the first time period is greater than or equal to V11, the signal quality prediction function is turned on.

[0155] For example, when the average value, minimum value, maximum value, weighted average value or median of the movement speed measured one or more times by the terminal device in the first time period is greater than or equal to V11, the signal quality prediction function is enabled.

[0156] For example, when the movement speed measured for the first time or the last time by the terminal device within the first time period is greater than or equal to V11, the signal quality prediction function is enabled.

[0157] Among them, this application does not limit the length of the first time period.

[0158] 2.2. The first speed threshold data includes a threshold value M11 for the number of cells passed by the terminal device in the first time period. The first speed data includes the number of cells passed by the terminal device in the first time period. If the number of cells passed by the terminal device in the first time period is greater than or equal to M11, the terminal device enables the signal quality prediction function. The present application does not impose any restrictions on the value of M11.

[0159] As an example, the number of cells passed by the terminal device in the first time period may be the average number of cells passed by the terminal device in the first time period.

[0160] Optionally, if 'the number of cells passed by the terminal device in the first time period is greater than M11', it can be considered that the terminal device is in a high-speed motion state.

[0161] 2.3. The first speed threshold data includes a threshold value M11 and a threshold value M12 for the number of cells passed by the terminal device in the first time period. The first speed data includes the number of cells passed by the terminal device in the first time period. If the number of cells passed by the terminal device in the first time period is less than or equal to M11 and greater than or equal to M12, the terminal device enables the signal quality prediction function. This application does not limit the values ​​of M11 and M12.

[0162] As an example, the number of cells passed by the terminal device in the first time period may be the average number of cells passed by the terminal device in the first time period.

[0163] Optionally, if 'the number of cells passed by the terminal device in the first time period is less than or equal to M11 and greater than or equal to M12', it can be considered that the terminal device is in a medium-speed movement state.

[0164] It should be noted that the combination of 2.1 and 2.2 can also be used as a way of "enabling the terminal device to enable the signal quality prediction function", or the combination of 2.1 and 2.3 can also be used as a way of "enabling the terminal device to enable the signal quality prediction function", which is not limited here.

[0165] 3. The first threshold data includes first distance threshold data. The terminal device can obtain the first distance data measured by the terminal device and enable the signal quality prediction function based on the size relationship between the first distance threshold data and the first distance data.

[0166] 3.1. The first distance threshold data includes a threshold value L11 of the difference between the terminal device's location and a first reference location, and a threshold value L12 of the difference between the terminal device's location and a second reference location. The first distance data includes a first distance between the terminal device's location and the first reference location, and a second distance between the terminal device's location and the second reference location. When the first distance is greater than or equal to L11 and the second distance is less than or equal to L12, the terminal device enables the signal quality prediction function. This application does not limit the size of L11 and L12.

[0167] The first reference position is the position corresponding to the serving cell of the terminal device, for example, the first reference position is the center position or any position of the serving cell. The second reference position is the position corresponding to the neighboring cell of the terminal device, for example, the second reference position is the center position or any position of the neighboring cell.

[0168] 3.2. The first distance threshold data includes the threshold value L11 of the difference between the position of the terminal device and the first reference position. The first distance data includes the first distance between the position of the terminal device and the first reference position. When the first distance is greater than or equal to L11, the terminal device turns on the signal quality prediction function.

[0169] 4. The first threshold data includes first power threshold data. The terminal device can obtain the first power data measured by the terminal device and enable the signal quality prediction function based on the size relationship between the first power threshold data and the first power data.

[0170] 4.1. The first power threshold data includes a remaining power threshold value P11. The first power data includes the remaining power of the terminal device. When the remaining power of the terminal device is greater than P11, the terminal device starts a signal quality prediction function.

[0171] Optionally, the remaining power of the terminal device may be an average value, a minimum value, a maximum value, a weighted average value, or a median value of the remaining power of the terminal device in time period 2. The application does not limit the length of time period 2.

[0172] 4.2. The first power threshold data includes a remaining power threshold value P11 and a remaining power threshold value P12. The first power data includes the remaining power of the terminal device. When the remaining power of the terminal device is less than P11 and greater than P12, the terminal device enables the signal quality prediction function.

[0173] The present application does not limit the values ​​of P11 and P12. P11 and P12 can be percentage thresholds, such as 80% and 50%, respectively. Alternatively, P11 and P12 can be absolute power thresholds, such as 200 mWh and 100 mWh, respectively.

[0174] Optionally, the remaining power of the terminal device may be an average value, a minimum value, a maximum value, a weighted average value or a median value of the remaining power of the terminal device in time period 2.

[0175] It should be pointed out that the above lists the various conditions for 'the terminal device to turn on the signal quality prediction function'. Any at least two of the above methods 1.1 to 1.5, method 2.1 and method 2.2 (or method 2.3), method 3.1 (or method 3.2) and method 4.1 (or method 4.2) can be combined as the conditions for 'the terminal device to turn on the signal quality prediction function'. This application does not limit the combination method.

[0176] Optionally, the first threshold data described above can also serve as a condition for "disabling the signal quality prediction function of the terminal device." In other words, the conditions for "enabling the signal quality prediction function of the terminal device" and "disabling the signal quality prediction function of the terminal device" are relative, or in other words, the conditions for "enabling the signal quality prediction function of the terminal device" and "disabling the signal quality prediction function of the terminal device" are opposite.

[0177] Exemplarily, when the signal quality measured by the terminal device for the serving cell is greater than H11, the terminal device turns off the signal quality prediction function.

[0178] For example, when the signal quality of the service cell measured by the terminal device once or multiple times in time period 1 is greater than H11, the terminal device turns off the signal quality prediction function.

[0179] For example, when the average value, minimum value, maximum value, weighted average value or median of the signal quality of the service cell measured by the terminal device once or multiple times in time period 1 is greater than H11, the terminal device turns off the signal quality prediction function.

[0180] For example, when the signal quality of the serving cell measured for the first or last time by the terminal device in time period 1 is greater than H11, the terminal device turns off the signal quality prediction function.

[0181] 2. The prediction function is the RLF failure prediction function

[0182] (1) The first threshold data includes a continuous out-of-sync indication threshold value N1. When the number of continuous out-of-sync indications obtained by the terminal device is greater than N1, the terminal device enables the RLF failure prediction function.

[0183] Optionally, N1 is an integer smaller than N310. This ensures that the terminal device can enable the RLF failure prediction function in time before an RLF failure occurs.

[0184] (2) The first threshold data includes a remaining duration threshold value T1 of the timer T310. When the remaining duration of the timer T310 in the terminal device is less than T1, the terminal device enables the RLF failure prediction function.

[0185] Generally, when the number of consecutive out-of-sync indications obtained by the terminal device is N310, timer T310 is started, and when the number of consecutive in-sync indications obtained by the terminal device is N311, timer T310 is stopped. When timer T310 times out, it is considered that an RLF failure has occurred.

[0186] Optionally, T1 may be smaller than the duration of timer T310 (or the value of timer T310 ), so as to ensure that the terminal device enables the RLF failure prediction function in time before an RLF failure occurs.

[0187] (3) The first threshold data includes a retransmission number threshold value N2 of the RLC PDU. When the retransmission number of the RLC PDU in the terminal device is greater than N2, the terminal device enables the RLF failure prediction function.

[0188] Optionally, N2 may be an integer less than the maximum number of retransmissions of the RLC PDU. The maximum number of retransmissions of the RLC PDU may be indicated by the network device to the terminal device. This ensures that the terminal device can promptly enable the RLF failure prediction function before an RLF failure occurs.

[0189] (4) The first threshold data includes a threshold value N3 of the number of times the random access preamble is sent. When the number of times the terminal device sends the random access preamble is greater than N3, the terminal device enables the RLF failure prediction function.

[0190] Optionally, N3 may be an integer less than the maximum number of random access preamble retransmissions. The network device may indicate the maximum number of random access preamble retransmissions to the terminal device. This ensures that the terminal device can enable the RLF failure prediction function in a timely manner before an RLF failure occurs.

[0191] (5) The first threshold data includes a threshold value N4 for consecutive listen-before-speak failures. When the number of consecutive listen-before-speak failures in the terminal device exceeds N4, the terminal device enables the RLF failure prediction function.

[0192] Optionally, N4 may be an integer less than the maximum number of consecutive LBT failures. The maximum number of consecutive LBT failures may be indicated by the network device to the terminal device. This ensures that the terminal device can enable the RLF failure prediction function in a timely manner before an RLF failure occurs.

[0193] (6) The first threshold data includes a signal quality threshold value H3 of the serving cell. When the signal quality measured by the terminal device for the serving cell is less than H3, the terminal device turns on the RLF failure prediction function.

[0194] Optionally, H3 may be less than a threshold for restoring the RRC connection of the terminal device in the serving cell. This threshold (i.e., the threshold for restoring the RRC connection of the terminal device in the serving cell) may be indicated by the network device to the terminal device. This ensures that the RLF failure prediction function is enabled in a timely manner before an RLF failure occurs.

[0195] It should be pointed out that the above lists the various conditions for "the terminal device to enable the signal quality prediction function". Any at least two of the above methods (1) to (6) can be combined as the conditions for "the terminal device to enable the RLF failure prediction function". This application does not limit the combination method.

[0196] In one possible implementation, after enabling the RLF failure prediction function, the terminal device may further ensure subsequent communication quality in the following manner, specifically:

[0197] 1. When an RLF failure is predicted, the terminal device sends signal quality data of related cells to the network device. The signal quality data of the related cells includes the signal quality of the terminal device's serving cell and / or the signal quality of the neighboring cell.

[0198] Optionally, the neighboring cell may be a neighboring cell with the best signal quality, which is not limited here.

[0199] Optionally, in this manner, the terminal device may further send second indication information to the network device, where the second indication information is used to indicate that the terminal device predicts an RLF failure. Upon learning from the second indication information that the terminal device predicts an RLF failure, the network device may perform a cell handover based on the signal quality data of the relevant cell. The specific handover process is not limited.

[0200] Optionally, the second indication information may be carried in an RRC message, UCI or MAC CE, which is not limited here.

[0201] 2. When an RLF failure is predicted, the terminal device performs a handover from a source cell to a target cell, where the target cell is one or more candidate cells, including a candidate cell configured with conditional handover (CHO) execution information. This application does not limit the specific process of "performing a handover from a source cell to a target cell."

[0202] The conditional handover execution information may include CHO trigger condition information corresponding to one or more candidate cells. The CHO trigger condition information is used to indicate the CHO trigger condition of the candidate cell, and the specific content is not limited here. Optionally, the conditional handover execution information may also include other information, such as random access channel (RACH) resources for accessing the candidate cell, etc., which is not limited here.

[0203] Optionally, the terminal device may further send second indication information to the network device, for example, when an RLF failure is predicted to occur, the terminal device may send the second indication information to the network device, wherein the second indication information is used to indicate to the terminal device that an RLF failure is predicted to occur.

[0204] Optionally, the second indication information may be carried in an RRC message, uplink control information (UCI) or MAC CE, which is not limited here.

[0205] 3. The prediction function is a cell handover failure prediction function

[0206] ①. The first threshold data includes a threshold value T2 of the remaining duration of the timer T304. When the remaining duration of the timer T304 in the terminal device is less than T2, the cell handover failure prediction function is enabled.

[0207] Among them, when the terminal device obtains the switching command (including reconfiguration synchronization (reconfigurationWithSync) information, the reconfigurationWithSync information contains one or more of the public configuration of the target cell, the identification of the terminal device, the value of timer T304, dedicated RACH resources, etc., which is used to instruct the terminal device to perform cell switching), it starts timer T304.

[0208] Optionally, T2 may be smaller than the duration of timer T304 (or the value of timer T304 ).

[0209] ②. The first threshold data includes a threshold value R1 for failure to perform random access to the target cell. When the number of times the terminal device fails to perform random access to the target cell is greater than R1, the cell handover failure prediction function is enabled.

[0210] Optionally, R1 is smaller than a maximum number of times that the terminal device fails to perform random access to the target cell, and the maximum number may be indicated to the terminal device by the network device.

[0211] It should be noted that the terminal device may have one or more prediction functions, for example, the terminal device may have one or more of a signal quality prediction function, an RLF failure prediction function, and a cell handover failure prediction function. The threshold data for enabling different prediction functions may be carried in the same message or in different messages, and this application does not limit this.

[0212] Optionally, when the terminal device turns on the corresponding prediction function, the terminal device may indicate to the network device the state of the prediction function. For example, the terminal device sends fourth indication information to the network device, where the fourth indication information is used to indicate that the prediction function is turned on.

[0213] In a possible embodiment, when one or more of the signal quality prediction function, the RLF failure prediction function, and the cell switching failure prediction function are turned on, the fourth indication information can be used to indicate that one or more of the signal quality prediction function, the RLF failure prediction function, and the cell switching failure prediction function are in the turned-on state.

[0214] Optionally, the fourth indication information may be carried in an RRC message, UCI or MAC CE, which is not limited here.

[0215] Referring to Figure 3, which is a flow chart of another communication method provided by an embodiment of the present application, the method includes the following steps 301 to 302.

[0216] 301. The terminal device obtains third indication information, where the third indication information is used to indicate second threshold data for disabling a prediction function.

[0217] For example, the terminal device receives third indication information from the network device.

[0218] Optionally, the third indication information may be carried in an RRC message, DCI or MAC CE, which is not limited in this application.

[0219] 302. The terminal device disables the prediction function based on the second threshold data.

[0220] In this application, the prediction function may be a signal quality prediction function, an RLF failure prediction function, or a cell handover failure prediction function. Step 302 is described below in combination with these cases. Specifically:

[0221] 1. The prediction function is the signal quality prediction function

[0222] 1. The second threshold data includes second signal quality threshold data. The terminal device can obtain the second signal quality data measured by the terminal device and disable the signal quality prediction function based on the size relationship between the second signal quality threshold data and the second signal quality data.

[0223] 1.1. The second signal quality threshold data includes a signal quality threshold value H21 of the serving cell. The second signal quality data includes the signal quality measured by the terminal device for the serving cell. When the signal quality measured by the terminal device for the serving cell is greater than or equal to H21, the terminal device disables the signal quality prediction function. The present application does not impose any restrictions on the value of H21.

[0224] As an example, the second signal quality data can be understood as: the signal quality of the serving cell measured once or multiple times by the terminal device in time period 2. In this case, it can be understood that: when the signal quality of the serving cell measured once or multiple times by the terminal device in time period 2 is greater than or equal to H21, the terminal device turns off the signal quality prediction function. In this application, the length of time period 2 is not limited.

[0225] As another example, the second signal quality data can be understood as: the average value, minimum value, maximum value, weighted average value or median of the signal quality of the serving cell measured multiple times by the terminal device in time period 2. In this case, it can be understood that: when the average value, minimum value, maximum value, weighted average value or median of the signal quality of the serving cell measured multiple times by the terminal device in time period 2 is greater than or equal to H21, the terminal device turns off the signal quality prediction function.

[0226] As another example, the second signal quality data can be understood as: the signal quality of the serving cell measured for the first time or the last time by the terminal device in time period 2. In this case, it can be understood that: when the signal quality of the serving cell measured for the first time or the last time by the terminal device in time period 2 is greater than or equal to H21, the terminal device turns off the signal quality prediction function.

[0227] Optionally, the number of times the terminal device measures the serving cell in time period 2 may be one or more times. The present application does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 2.

[0228] 1.2. The second signal quality threshold data includes a threshold value H22 of the difference between the signal quality of the neighboring cell and the signal quality of the primary cell. The second signal quality data includes the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the primary cell. When the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the primary cell is less than or equal to H22, the terminal device disables the signal quality prediction function. The present application does not limit the size of H22.

[0229] As an example, the second signal quality data can be understood as: the signal quality of the neighboring cell measured K times by the terminal device in time period 2 and the signal quality of the primary cell measured K times, where K is an integer less than or equal to 1. In this case, turning off the signal quality prediction function in this manner can be understood as:

[0230] For example, if the difference between the signal quality of the neighboring cell measured K times by the terminal device in time period 2 and the signal quality of the corresponding main cell is less than or equal to H22, the terminal device turns off the signal quality prediction function. Specifically, assuming that the signal quality of the neighboring cell measured three times by the terminal device in time period 2 is signal quality 1 to signal quality 3, and the signal quality of the main cell measured three times by the terminal device in time period 2 is signal quality A to signal quality C, signal quality 1 is less than signal quality A, and the difference between signal quality 1 and signal quality A is less than or equal to H22; signal quality 2 is less than signal quality B, and the difference between signal quality 2 and signal quality B is less than or equal to H22, and so on, which will not be elaborated here.

[0231] For example, if the difference between the average value of the signal quality of the neighboring cell measured K times by the terminal device in time period 2 and the average value of the signal quality of the primary cell measured K times by the terminal device in time period 2 is less than or equal to H22, the terminal device disables the signal quality prediction function. The average value here can be replaced by: minimum value, maximum value, weighted average value, or median value.

[0232] For example, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 and the signal quality of the primary cell measured for the first time by the terminal device in time period 2 is less than or equal to H22, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 and the signal quality of the primary cell measured for the last time by the terminal device in time period 2 is less than or equal to H22, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 and the signal quality of the primary cell measured for the last time by the terminal device in time period 2 is less than or equal to H22, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 and the signal quality of the primary cell measured for the first time by the terminal device in time period 2 is less than or equal to H22, the terminal device turns off the signal quality prediction function.

[0233] It should be noted that the above lists some possible implementation methods of 'disabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0234] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 2 may be the same as or different from the number of times the terminal device measures the signal quality of the primary cell in time period 2, and this application does not limit this.

[0235] Optionally, the terminal device may measure the neighboring cell once or more times in time period 2, and the terminal device may measure the primary cell once or more times in time period 2. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 2.

[0236] 1.3. The second signal quality threshold data includes a signal quality threshold value H23 of a neighboring cell. The second signal quality data includes the signal quality of the neighboring cell measured by the terminal device. When the signal quality measured by the terminal device for the neighboring cell is less than or equal to H23, the terminal device disables the signal quality prediction function. The present application does not impose any restrictions on the value of H23.

[0237] As an example, the second signal quality data can be understood as: the signal quality of the neighboring area measured one or more times by the terminal device in time period 2. In this case, it can be understood that: when the signal quality of the neighboring area measured one or more times by the terminal device in time period 2 is less than or equal to H23, the signal quality prediction function is turned off.

[0238] As another example, the second signal quality data can be understood as: the average value, minimum value, maximum value, weighted average value or median of the signal quality of the neighboring area measured multiple times by the terminal device in time period 2. In this case, it can be understood that: when the average value, minimum value, maximum value, weighted average value or median of the signal quality of the neighboring area measured multiple times by the terminal device in time period 2 is less than or equal to H23, the signal quality prediction function is turned off.

[0239] As another example, the second signal quality data can be understood as: the signal quality of the neighboring area measured for the first time or the last time by the terminal device in time period 2. In this case, it can be understood that: when the signal quality of the neighboring area measured for the first time or the last time by the terminal device in time period 2 is less than or equal to H23, the signal quality prediction function is turned off.

[0240] The number of times the terminal device measures the neighboring cell in time period 2 may be one or more times. The present application does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 2.

[0241] 1.4. The second signal quality threshold data includes a signal quality threshold value H24 of the primary cell and a signal quality threshold value H25 of the neighboring cell. The second signal quality data includes the signal quality measured by the terminal device for the primary cell and the signal quality measured by the terminal device for the neighboring cell. When the signal quality measured by the terminal device for the primary cell is greater than or equal to H24 and the signal quality measured by the terminal device for the neighboring cell is less than or equal to H25, the terminal device disables the signal quality prediction function. This application does not limit the values ​​of H24 and H25.

[0242] As an example, the second signal quality data can be understood as: the signal quality of the neighboring cell measured S times by the terminal device in time period 2 and the signal quality of the primary cell measured S times, where S is an integer greater than or equal to 1. In this case, turning off the signal quality prediction function in this manner can be understood as:

[0243] For example, if the signal quality of the main cell measured S times by the terminal device in time period 2 is greater than or equal to H24, and the signal quality of the neighboring cell measured S times by the terminal device in time period 2 is less than or equal to H25, the terminal device turns off the signal quality prediction function.

[0244] For example, if the average value (which can be replaced by: minimum value, maximum value, weighted average value or median) of the signal quality of the main cell measured S times by the terminal device in time period 2 is greater than or equal to H24, and the average value (which can be replaced by: minimum value, maximum value, weighted average value or median) of the signal quality of the neighboring cell measured S times by the terminal device in time period 2 is less than or equal to H25, the terminal device turns off the signal quality prediction function.

[0245] For example, if the signal quality of the primary cell measured for the first time by the terminal device in time period 2 is greater than or equal to the threshold value H24, and the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 is less than or equal to the threshold value H25, the terminal device turns off the signal quality prediction function. Or, if the signal quality of the primary cell measured for the last time by the terminal device in time period 2 is greater than or equal to the threshold value H24, and the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 is less than or equal to the threshold value H25, the terminal device turns off the signal quality prediction function. Or, if the signal quality of the primary cell measured for the first time by the terminal device in time period 2 is greater than or equal to the threshold value H24, and the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 is less than or equal to the threshold value H25, the terminal device turns off the signal quality prediction function. Or, if the signal quality of the primary cell measured for the last time by the terminal device in time period 2 is greater than or equal to the threshold value H24, and the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 is less than or equal to the threshold value H25, the terminal device turns off the signal quality prediction function.

[0246] It should be noted that the above lists some possible implementation methods of 'disabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0247] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 2 may be the same as or different from the number of times the terminal device measures the signal quality of the primary cell in time period 2, and this application does not limit this. Optionally, the number of times the terminal device measures the neighboring cell in time period 2 may be one or more times, and the number of times the terminal device measures the primary cell in time period 2 may be one or more times. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 2.

[0248] 1.5. The second signal quality threshold data includes a threshold value H26 of the difference between the signal quality of the neighboring cell and the signal quality of the secondary cell. The second signal quality data includes the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the secondary cell. If the difference between the signal quality measured by the terminal device for the neighboring cell and the signal quality measured by the terminal device for the secondary cell is less than or equal to H26, the signal quality prediction function is disabled. The present application does not limit the size of H26.

[0249] As an example, the second signal quality data can be understood as: the signal quality of the neighboring cell measured X times and the signal quality of the secondary cell measured X times by the terminal device in time period 2, where X is an integer less than or equal to 1. In this case, turning off the signal quality prediction function in this manner can be understood as:

[0250] For example, if the difference between the signal quality of the neighboring cell measured by the terminal device X times in time period 2 and the signal quality of the corresponding secondary cell is less than or equal to the threshold value H26, the terminal device turns off the signal quality prediction function. Specifically, assuming that the signal quality of the neighboring cell measured three times by the terminal device in time period 2 is signal quality 1 to signal quality 3, and the signal quality of the secondary cell measured three times by the terminal device in time period 2 is signal quality A to signal quality C, signal quality 1 is less than signal quality A, and the difference between signal quality 1 and signal quality A is less than or equal to the threshold value H26; signal quality 2 is less than signal quality B, and the difference between signal quality 2 and signal quality B is less than or equal to the threshold value H26, and so on, it will not be repeated here.

[0251] For example, if the difference between the average value of the signal quality of the neighboring cell measured by the terminal device X times in time period 2 and the average value of the signal quality of the secondary cell measured by the terminal device X times in time period 2 is less than or equal to threshold value H26, the terminal device disables the signal quality prediction function. The average value here can be replaced by: minimum value, maximum value, weighted average value, or median value.

[0252] For example, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 and the signal quality of the secondary cell measured for the first time by the terminal device in time period 2 is less than or equal to the threshold value H26, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 and the signal quality of the secondary cell measured for the last time by the terminal device in time period 2 is less than or equal to the threshold value H26, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the first time by the terminal device in time period 2 and the signal quality of the secondary cell measured for the first time by the terminal device in time period 2 is less than or equal to the threshold value H26, the terminal device turns off the signal quality prediction function. Or, if the difference between the signal quality of the neighboring cell measured for the last time by the terminal device in time period 2 and the signal quality of the secondary cell measured for the first time by the terminal device in time period 2 is less than or equal to the threshold value H26, the terminal device turns off the signal quality prediction function.

[0253] It should be noted that the above lists some possible implementation methods of 'disabling the signal quality prediction function of the terminal device'. There may be other combinations, which are not listed here one by one.

[0254] Optionally, the number of times the terminal device measures the signal quality of the neighboring cell in time period 2 may be the same as or different from the number of times the terminal device measures the signal quality of the secondary cell in time period 2, and this application does not limit this. Optionally, the number of times the terminal device measures the neighboring cell in time period 2 may be one or more times, and the number of times the terminal device measures the secondary cell in time period 2 may be one or more times. This application also does not limit the number of times the terminal device measures the signal quality of the corresponding cell in time period 2.

[0255] For example, the scenarios involved in the above-mentioned methods 1.1 to 1.5 are similar to those in FIG2 and are not described in detail here.

[0256] 2. The second threshold data includes second speed threshold data. The terminal device can obtain the second speed data measured by the terminal device and disable the signal quality prediction function based on the size relationship between the second speed threshold data and the second speed data.

[0257] 2.1. The second speed threshold data includes a speed threshold value V21. The second speed data includes the movement speed of the terminal device. When the movement speed of the terminal device is less than or equal to V21, the terminal device turns off the signal quality prediction function. This application does not limit the size of V21.

[0258] As an example, the movement speed of the terminal device may include the movement speed of the terminal device measured once or multiple times during the second time period. In this case, turning off the signal quality prediction function in this manner can be understood as:

[0259] For example, when the movement speed measured once or multiple times by the terminal device in the second time period is less than or equal to V21, the signal quality prediction function is turned off.

[0260] For example, when the average value, minimum value, maximum value, weighted average value or median of the movement speed measured one or more times by the terminal device in the second time period is less than or equal to V21, the signal quality prediction function is turned off.

[0261] For example, when the movement speed measured for the first time or the last time by the terminal device in the second time period is less than or equal to V21, the signal quality prediction function is turned off.

[0262] The present application does not limit the duration of the second time period.

[0263] 2.2. The second speed threshold data includes a threshold value M21 for the number of cells passed by the terminal device during the second time period. The second speed data includes the number of cells passed by the terminal device during the second time period. If the number of cells passed by the terminal device during the second time period is less than or equal to M21, the terminal device disables the signal quality prediction function. The present application does not impose any restrictions on the value of M21.

[0264] As an example, the number of cells passed by the terminal device in the second time period may be the average number of cells passed by the terminal device in the second time period.

[0265] Optionally, if 'the number of cells passed by the terminal device in the second time period is less than or equal to M21', it can be considered that the terminal device is in a low-speed movement state.

[0266] 2.3. The second speed threshold data includes a threshold value M21 and a threshold value M22 for the number of cells passed by the terminal device in the second time period. The second speed data includes the number of cells passed by the terminal device in the second time period. If the number of cells passed by the terminal device in the second time period is greater than or equal to M21 and less than or equal to M22, the terminal device disables the signal quality prediction function. This application does not limit the values ​​of M21 and M22.

[0267] As an example, the number of cells passed by the terminal device in the second time period may be the average number of cells passed by the terminal device in the second time period.

[0268] Optionally, if 'the number of cells passed by the terminal device in the second time period is greater than or equal to M21 and less than or equal to M22', it can be considered that the terminal device is in a medium-speed movement state.

[0269] It should be noted that the combination of 2.1 and 2.2 can also be used as a way of "the terminal device turns off the signal quality prediction function", or the combination of 2.1 and 2.3 can also be used as a way of "the terminal device turns off the signal quality prediction function", which is not limited here.

[0270] 3. The second threshold data includes second distance threshold data. The terminal device can obtain the second distance data measured by the terminal device and disable the signal quality prediction function based on the size relationship between the second distance threshold data and the second distance data.

[0271] 3.1. The second distance threshold data includes a threshold value L21 for the difference between the terminal device's location and the first reference location, and a threshold value L22 for the difference between the terminal device's location and the second reference location. The second distance data includes a first distance between the terminal device's location and the first reference location, and a second distance between the terminal device's location and the second reference location. When the first distance is less than or equal to L21 and the second distance is greater than or equal to L22, the terminal device disables the signal quality prediction function. This application does not limit the size of L21 and L22.

[0272] The first reference position is the position corresponding to the serving cell of the terminal device, for example, the first reference position is the center position or any position of the serving cell. The second reference position is the position corresponding to the neighboring cell of the terminal device, for example, the second reference position is the center position or any position of the neighboring cell.

[0273] 3.2. The second distance threshold data includes the threshold value L21 of the difference between the position of the terminal device and the first reference position. The second distance data includes the first distance between the position of the terminal device and the first reference position. When the first distance is less than or equal to L21, the terminal device turns off the signal quality prediction function.

[0274] 4. The second threshold data includes second power threshold data. The terminal device can obtain the second power data measured by the terminal device and disable the signal quality prediction function based on the size relationship between the second power threshold data and the second power data.

[0275] 4.1. The second power threshold data includes a remaining power threshold value P21 and a remaining power threshold value P22. The second power data includes the remaining power of the terminal device. When the remaining power of the terminal device is less than or equal to P21 and greater than or equal to P22, the terminal device turns off the signal quality prediction function.

[0276] The present application does not limit the values ​​of P21 and P22. P21 and P22 can be percentage thresholds, such as 80% and 50%, respectively. Alternatively, P21 and P22 can be absolute power thresholds, such as 200 mWh and 150 mWh, respectively.

[0277] Optionally, the remaining power of the terminal device may be an average value, a minimum value, a maximum value, a weighted average value, or a median value of the remaining power of the terminal device in time period 2. The application does not limit the length of time period 2.

[0278] 4.2. The second power threshold data includes a remaining power threshold value P22. The second power data includes the remaining power of the terminal device. When the remaining power of the terminal device is less than or equal to P22, the terminal device turns off the signal quality prediction function.

[0279] Optionally, the remaining power of the terminal device may be an average value, a minimum value, a maximum value, a weighted average value or a median value of the remaining power of the terminal device in time period 2.

[0280] It should be pointed out that the above lists the various conditions for 'the terminal device turns off the signal quality prediction function'. Any at least two of the above methods 1.1 to 1.5, method 2.1 and method 2.2 (or method 2.3), method 3.1 (or method 3.2) and method 4.1 (or method 4.2) can be combined as the conditions for 'the terminal device turns off the signal quality prediction function'. This application does not limit the combination method.

[0281] Optionally, the second threshold data described above can also serve as a condition for "enabling the signal quality prediction function on the terminal device." That is, the condition for "enabling the signal quality prediction function on the terminal device" and the condition for "disabling the signal quality prediction function on the terminal device" are relative, or in other words, the condition for "enabling the signal quality prediction function on the terminal device" and the condition for "disabling the signal quality prediction function on the terminal device" are opposite.

[0282] Exemplarily, when the signal quality measured by the terminal device for the serving cell is less than H21, the terminal device turns off the signal quality prediction function.

[0283] For example, when the signal quality of the service cell measured by the terminal device once or multiple times within time period 2 is less than H21, the terminal device turns off the signal quality prediction function.

[0284] For example, when the average value, minimum value, maximum value, weighted average value or median of the signal quality of the service cell measured by the terminal device once or multiple times in time period 2 is less than H21, the terminal device turns off the signal quality prediction function.

[0285] For example, when the signal quality of the service cell measured for the first or last time by the terminal device in time period 2 is less than H21, the terminal device turns off the signal quality prediction function.

[0286] 2. The prediction function is the RLF failure prediction function

[0287] (1) The second threshold data includes a continuous synchronization indication threshold value N5. When the number of continuous synchronization indications obtained by the terminal device is greater than N5, the terminal device turns off the RLF failure prediction function.

[0288] Optionally, N5 is an integer smaller than N311. This ensures that the terminal device disables the RLF failure prediction function in time before an RLF failure occurs.

[0289] (2) The second threshold data includes the maximum retransmission number threshold value N6 of the RLC PDU. If the RLC PDU is successfully retransmitted before the retransmission number of the RLC PDU in the terminal device reaches N6, the terminal device turns off the RLF failure prediction function.

[0290] (4) The second threshold data includes a maximum threshold value N7 of the number of times the random access preamble is sent. If the terminal device successfully accesses the random access before the number of times the random access preamble is sent reaches N7, the terminal device disables the RLF failure prediction function.

[0291] (5) The second threshold data includes the maximum threshold value N8 for consecutive listen-before-speak failures. If the terminal device successfully performs LBT before the number of consecutive LBT failures reaches N8, the terminal device disables the RLF failure prediction function.

[0292] It should be pointed out that the above lists the various conditions for 'the terminal device to turn off the signal quality prediction function'. Any at least two of the above methods (1) to (5) can be combined as the conditions for 'the terminal device to turn off the RLF failure prediction function'. This application does not limit the combination method.

[0293] Referring to Figure 4 , which is a flow chart of another communication method provided by an embodiment of the present application, the method includes the following steps 401 to 402 .

[0294] 401. The terminal device obtains sixth indication information, where the sixth indication information is used to instruct the terminal device to turn off the prediction function when random access to the target cell is successful.

[0295] For example, the terminal device receives sixth indication information from the network device. The prediction function in the embodiment shown in FIG4 is a cell handover failure prediction function.

[0296] Optionally, the sixth indication information may be carried in an RRC message, DCI or MAC CE, which is not limited in this application.

[0297] 402. The terminal device successfully performs random access to the target cell and turns off the prediction function.

[0298] It should be noted that in the embodiments described in FIG. 3 or FIG. 4 , the terminal device may have one or more prediction functions. For example, the terminal device may have one or more of a signal quality prediction function, an RLF failure prediction function, and a cell handover failure prediction function. The relevant information for disabling different prediction functions may be carried in the same message or in different messages, and this application does not limit this.

[0299] Optionally, when the terminal device turns off the corresponding prediction function, the terminal device may indicate to the network device the state of the prediction function. For example, the terminal device sends fifth indication information to the network device, where the fifth indication information is used to indicate that the prediction function is turned off.

[0300] In a possible implementation, when one or more of the signal quality prediction function, the RLF failure prediction function, and the cell switching failure prediction function are turned off, the fifth indication information may be used to indicate that one or more of the signal quality prediction function, the RLF failure prediction function, and the cell switching failure prediction function are in a turned-off state.

[0301] Optionally, the fifth indication information may be carried in an RRC message, UCI or MAC CE, which is not limited here.

[0302] It should be noted that in this application, there is no necessary order between enabling a prediction function and disabling it on a terminal device. For example, a terminal device may enable a prediction function first and then disable it. Or vice versa.

[0303] For example, the terminal device may first enable the prediction function based on the first threshold data, and then disable the prediction function based on the second threshold data. The reverse is also possible. The prediction function here may be a signal quality prediction function, an RLF failure prediction function, or a cell handover failure prediction function.

The reverse is also possible. The prediction function here may be a signal quality prediction function.
