[0033] The technical solution of this application will be described below with reference to the accompanying drawings. To facilitate understanding of this application, the communication process involved in the embodiment of this application will be described below with reference to Figures 1 to 8.

[0034] Dual-connection communication scenario

[0035] Currently, with the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP international standards organization has begun developing fifth-generation (5G) communication systems. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine-type communications (mMTC).

[0036] eMBB still aims to provide users with multimedia content, services, and data, and demand for this technology is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it cannot be generalized and requires detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical characteristics of mMTC include high connection density, small data volumes, latency-insensitive services, low module costs, and long service life.

[0037] In the early days of new radio (NR) deployment, complete NR coverage was difficult to achieve. Consequently, typical network coverage consisted of wide-area Long Term Evolution (LTE) coverage and NR island coverage. Furthermore, a large portion of LTE was deployed below 6 GHz, leaving limited spectrum available for 5G. Therefore, NR must explore spectrum applications above 6 GHz, but high-frequency bands suffer from limited coverage and rapid signal fading.

[0038] In order to realize the deployment and commercial application of 5G networks as soon as possible, 3GPP first completed the first 5G version, namely EN-DC (LTE-NR dual connectivity) before the end of December 2017. Figure 1 is a schematic diagram of the network architecture of EN-DC. Referring to Figure 1, EN-DC is a DC with an LTE base station (such as eNB) as the master node (MN) or main base station and an NR base station (such as gNB) as the secondary node (SN) or secondary base station, and the MN and SN can respectively establish data plane connections with the evolved packet core (EPC) network (i.e., the core network of the fourth generation (4G) communication system) to provide air interface transmission resources for data between terminal devices and EPC. Among them, EPC can include a mobility management entity (MME) and / or a serving gate way (S-GW).

[0039] It should be noted that in the architecture shown in Figure 1, the S1 interface is the communication interface between the LTE base station and the EPC. Based on the type of information transmitted in the S1 interface, the S1 interface can be divided into the S1-U interface and the S1-C interface. The S1-U interface can be used to transmit user plane data, and the S1-C interface can be used to transmit control plane signaling.

[0040] The following describes the connection method between the terminal device and the network device in the EN-DC dual connection scenario by taking the two networking methods shown in Figures 2 and 3 as examples.

[0041] As shown in Figure 2, the LTE eNB, acting as the mobile node, establishes both the S1-U and S1-C interfaces with the EPC. The gNB, acting as the network node, establishes the S1-U interface with the EPC. In this architecture, control plane signaling between the EPC and the base station is transmitted only between the EPC and the LTE eNB. The LTE eNB then forwards specific control plane signaling to the gNB. User plane data, however, can be transmitted between the EPC and the LTE eNB, and between the EPC and the gNB.

[0042] As shown in Figure 3, the LTE eNB, acting as a mobile node, establishes an S1-U interface and an S1-C interface with the EPC. The gNB, acting as a network node, does not communicate directly with the EPC. In this architecture, control plane signaling and user plane data transmission between the EPC and the base station must be transmitted only between the EPC and the LTE eNB. The LTE eNB then transmits specific control plane signaling and / or user plane data to the gNB.

[0043] It should be noted that in the networking modes shown in Figures 2 and 3, both the MN and the SN may be provided with RRC entities to generate RRC PDUs, see Figure 4. However, at the same time, the terminal device usually has only one RRC state machine and it is based on the MN side.

[0044] It should also be noted that in LTE, signaling bearers can include signaling radio bearers (SRB) 0, SRB1, and SRB2. EN-DC can further support SRB3 on this basis. SRB3 is used to transmit RRC signaling between SN and terminal equipment. The generation of this signaling bearer does not require resource negotiation and UE capability negotiation with MN. In addition, in order to improve the reliability of SRB1 and SRB2 transmission, EN-DC can also support split SRB1 (split SRB1) and split SRB2, that is, the packet data convergence protocol protocol data unit (PDCP PDU) corresponding to the RRC message generated by MN is repeatedly transmitted on the SN side.

[0045] The method provided in the embodiments of the present application can be used in various multi-RAT dual connectivity (MR-DC) architectures, such as dual connectivity between a 4G communication system and a 5G communication system, dual connectivity between a 5G communication system and a 4G communication system, or dual connectivity between a 5G communication system and a 5G communication system.

[0046] The dual connectivity between the 4G communication system and the 5G communication system may include: Evolved Universal Terrestrial Radio Access (E-UTRA) system and New Radio (NR) system dual connectivity (E-UTRA-NR dual connectivity, EN-DC), and E-UTRA system and NR system dual connectivity (NG-RAN E-UTRA-NR dual connectivity, NGEN-DC) under the 5G core network. EN-DC may also be referred to as option 3 series.

[0047] NG EN-DC, also known as Option 7 series, is a DC that uses an LTE base station (e.g., ng-eNB) as the mobile network (MN) and an NR base station (e.g., gNB) as the network service (SN). Unlike EN-DC, in NG EN-DC, both the mobile network (MN) and the network service (SN) can connect to the 5G core network (5GC), providing air interface transmission resources for data between terminal devices and the 5GC.

[0048] Dual connectivity between the 5G communication system and the 4G communication system can include dual connectivity between the NR system and the E-UTRA system (NE-DC). NE-DC is also known as Option 4 series. NE-DC uses an NR base station (e.g., gNB) as the mobile node and an LTE base station (e.g., ng-eNB) as the network node. Both the mobile node and the network node can have data plane connections with the 5GC, providing air interface transmission resources for data between the terminal device and the 5GC.

[0049] The dual connection between the 5G communication system and the 5G communication system may include the DC between the NR system and the NR system. In the DC between the NR system and the NR system, both the MN and the SN are NR base stations.

[0050] The previous article introduced a variety of dual-connection networking methods. The following, combined with Figures 5 to 7, introduces the dual-connection networking methods based on different types of master nodes.

[0051] Figure 5 illustrates a dual-connectivity (EN-DC) networking configuration with an LTE eNB serving as the master node. As shown in Figure 5, the LTE eNB serves as the mobile node (MN) and the NR gNB serves as the network (SN). In this architecture, control plane signaling between the EPC and the base station is transmitted only between the EPC and the LTE eNB. The LTE eNB then forwards specific control plane signaling to the gNB. User plane data, however, can be transmitted between the EPC and the LTE eNB, and between the EPC and the gNB.

[0052] Figure 6A illustrates an example of an eLTE eNB-5GC connection. Figure 6B illustrates an example of a dual-connectivity (i.e., NGEN-DC) networking configuration with the eNB acting as the master node in Figure 6A. Referring to Figure 6B, an NR gNB can connect to a 5GC, and an eLTE eNB and NR gNB can form an NGEN-DC architecture, where the eLTE eNB connected to the 5GC acts as a mobile node (MN) and the NR gNB acts as a signaling node (SN). In this architecture, both the mobile node (MN) and the signaling node (SN) can connect to the 5GC, and user plane data between the mobile node and the signaling node can be aggregated via the 5GC. Control plane signaling, however, can only be transmitted between the 5GC and the eNB, and then forwarded by the eNB to the gNB.

[0053] Figure 7A is an example diagram of an NR gNB connected to a 5GC. Figure 7B is an example diagram of a dual-connectivity (i.e., NE-DC) networking configuration in which the gNB in ​​Figure 7A serves as the master node. Referring to Figure 7B , an eLTE eNB can connect to a 5GC and serve as a SN. In this architecture, both the mobile node and the SN can connect to the 5GC, and user-plane data between the mobile node and the SN can be aggregated via the 5GC. Control-plane signaling can only be transmitted between the 5GC and the gNB, and then forwarded by the gNB to the eNB. Figure 7C is another example diagram of a dual-connectivity (i.e., NR-DC) networking configuration in which the gNB in ​​Figure 7A serves as the master node. Referring to Figure 7C , an NR gNB can connect to a 5GC and serve as a SN. In this architecture, both the mobile node and the SN can connect to the 5GC, and user-plane data between the mobile node and the SN can be aggregated via the 5GC. Control-plane signaling can only be forwarded from the mobile node to the SN.

[0054] The following describes a communication system applicable to the embodiment of the present application by taking the communication system 80 shown in Figure 8 as an example.

[0055] Figure 8 is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Referring to Figure 8 , communication system 80 may include network device 801, network device 802, network device 805, terminal device 803, and terminal device 804. Figure 8 is merely a schematic diagram and does not limit the applicable scenarios of the technical solutions provided in this application.

[0056] The network device in Figure 8, namely network device 801, network device 802 or network device 805, can be any device with wireless transceiver functions. Including but not limited to: evolutionary Node B (NodeB or eNB or e-NodeB) in LTE, base station (gNodeB or gNB) or transmission receiving point (transmission reception point / transmission reception point, TRP) in NR, subsequent evolution of 3GPP, etc. The base station can be: macro base station, micro base station, pico base station, small station, relay station, or balloon station, etc. Multiple base stations can support the network of the same technology mentioned above, or they can support the networks of different technologies mentioned above. The base station can include one or more co-site or non-co-site TRPs. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario.

[0057] The terminal in Figure 8, namely the terminal device 803 or the terminal device 804, is a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a terminal in industrial control, a vehicle-mounted terminal device, a terminal in self-driving, a terminal in assisted driving, a terminal in remote medical care, a terminal in smart grid, a terminal in transportation safety, a terminal in smart city, a terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. A terminal may also be sometimes referred to as terminal equipment, user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal equipment, wireless communication equipment, machine terminal, UE agent, or UE device. A terminal can be fixed or mobile.

[0058] As an example and not a limitation, in an embodiment of the present 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. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those 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 those that only 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.

[0059] In addition, NR can also be deployed independently. In the 5G communication system, the maximum channel bandwidth can be 400MHz (wideband carrier), which is very large compared to the maximum 20M bandwidth of LTE. In the NR stand alone (SA) system, the rate can be increased through CA, that is, bandwidth is exchanged for rate. At present, carrier aggregation is usually performed between carriers with the same site and the same RAT. Each carrier participating in carrier aggregation is called a component carrier. Among the component carriers, the component carrier that carries signaling transmission and manages other component carriers is called the main carrier, also called the primary cell (PCell); the secondary carrier is also called the secondary cell (SCell). Among them, the secondary cell can be used to expand the bandwidth and increase the rate, and the main carrier decides when to add or release the secondary cell.

[0060] Cell switching

[0061] Cell handover (HO) aims to improve the continuity of services provided by the communication system to terminal devices. In a wireless communication system, when a terminal device moves from one cell (also known as the "source cell") to another, it needs to be handed over to another cell (also known as the "target cell") to maintain communication. The cell can be a primary cell (PCell) or a primary secondary cell (PSCell). Generally, cell handover can be divided into two types: traditional handover mechanism and conditional handover mechanism.

[0062] In a traditional handover mechanism, to improve the continuity of services provided by the communication system to connected terminal devices, the network device will send a handover command to the terminal device at an appropriate time (for example, when the signal measurement result of the terminal device in the serving cell falls below a threshold) to instruct the terminal device to perform a cell handover. In some implementations, the handover command may be an RRC reconfiguration message containing synchronization reconfiguration information.

[0063] For the conditional handover (CHO) mechanism, the network device can configure the configuration of one or more target cells, and the conditional handover events associated with one or more conditional handover target cells to the terminal device. Accordingly, the terminal device can perform a handover condition evaluation task to evaluate whether the conditional handover events associated with the above-mentioned one or more conditional handover target cells are satisfied. When the one or more conditional handover events associated with the above-mentioned one or more conditional handover target cells are satisfied, the terminal device can switch from the source cell (or "current serving cell") to the corresponding conditional handover target cell that meets the conditional handover event.

[0064] The CHO introduced in the R16 standard version does not support candidate cell configurations including secondary cell group (SCG) group configurations. In order to support CHO in MR-DC scenarios, RAN3 further enhanced the signaling design between the Xn interface during the R17 discussion phase to support the inclusion of an SCG configuration in the CHO candidate cell configuration. The potential problem with this configuration method is that when the terminal device determines the target PCell based on the execution conditions, the link quality of the PSCell associated with the PCell may become insufficient, or it may not be a suitable PSCell, which will result in the terminal device being unable to successfully access the PSCell. In order to further optimize the impact of mobility on DC scenario throughput, the R18 mobility enhancement further introduces a PSCell evaluation process based on the R17 CHO with SCG, which is called CHO with candidate SCGs. The relevant definitions in the protocol are as follows.

[0065] A CHO with candidate SCG(s) is defined as a PCell change with PSCell addition / change that is executed by the UE when the execution conditions for both PCell and the associated PSCell are met. The UE evaluates the execution conditions for candidate PCell(s) and candidate PSCell(s) simultaneously upon receiving the CHO with candidate SCG(s) configuration, and stops evaluating the execution conditions once PCell change or PSCell change is triggered. The UE does not execute CHO with candidate SCG(s)until the execution conditions for both PCell and the associated PSCell are met.

[0066] In related technologies, network equipment can provide cell handover configurations to terminal devices based on measurement results reported by terminal devices, such as performing SCell addition / change / release or SCG addition / change / release procedures in scenarios supporting CA / DC deployment. However, this approach has some problems.

[0067] For example, if the location of the terminal device changes, the terminal device may not be able to access the target cell based on the above-mentioned cell switching configuration. This is because the reported measurement results can usually only reflect the current channel quality of the target frequency / cell, and as the location of the terminal device changes, the wireless link situation of the target frequency / cell relative to the terminal device will also change accordingly. As an example, based on the current measurement results (such as the measurement results reported to the network device at time 1), cell 1 under frequency 1 has the best measurement results (such as meeting the access requirements). But in fact, the terminal device will soon move out of the coverage of cell 1 and move to cell 2 under frequency 2. If the network device provides the terminal device with a cell switching configuration based on the measurement results received at time 1, it is likely that the terminal device will fail to switch, resulting in service interruption.

[0068] For example, in a scenario that supports CA / DC deployment, based on the current cell measurement results reported by the terminal device, it may not be possible to determine the relevant information of the target secondary cell, or there may be some unnecessary information in the reported content, resulting in a large signaling overhead. This is because the terminal device does not know which base stations / cells can form a CA / DC relationship. Therefore, the measurement results reported by the terminal device may not be sufficient to help the network device determine the target SCell / SCG configuration and its activation / deactivation status, or there may be some unnecessary information in the reported content, resulting in a large signaling overhead.

[0069] Figure 9 is a flow chart of a wireless communication method provided by an embodiment of the present application to solve the above-mentioned problem. The method shown in Figure 9 involves the interaction between a network device and a terminal device. The following will introduce the method provided by an embodiment of the present application from the perspective of the interaction between the terminal device and the network device.

[0070] The method shown in Figure 9 may include step S910. In step S910, the terminal device receives first configuration information sent by the network device, or in other words, the network device sends the first configuration information to the terminal device.

[0071] The first configuration information is associated with the first report of the terminal device. For example, the first configuration information can be used to determine the reporting content of the first report and / or the conditions for triggering the first report.

[0072] In some embodiments, the first report may be associated with a cell handover of the terminal device, or in other words, the first report is used to determine information associated with the cell handover of the terminal device, such as a cell handover configuration.

[0073] In some embodiments, the reporting content of the first report may include first prediction information, and the first prediction information may be associated with the predicted value of the cell measurement result. The predicted value of the cell measurement result can be obtained based on technologies such as artificial intelligence (AI). For example, AI technology can be used to predict the trajectory information of the terminal device and the channel quality of the target frequency / cell. Then the terminal device can report the cell / frequency information that meets the access requirements of the terminal device in the future period based on the predicted trajectory of the terminal device in the future period. As mentioned in the example above, cell 1 under frequency 1 has the best measurement result in the measurement result at time 1, but the terminal device quickly moves out of the coverage of cell 1 and moves to cell 2 under frequency 2. Using the method provided in the embodiment of the present application, the terminal device can report cell 2 under frequency 2 to the network device instead of reporting cell 1 under frequency 1, thereby avoiding service interruption caused by the terminal device attempting to access cell 1.

[0074] In some embodiments, the first configuration information may include a frequency / cell configuration, which may include, for example, a frequency / cell that the network device is interested in. The frequency / cell configuration may be determined based on information known to the network device, such as a positional relationship between the terminal device and the frequency / cell.

[0075] In some embodiments, the content of the first report may be associated with the frequency / cell in the first configuration information, or may be unassociated with the frequency / cell in the first configuration information. For example, the terminal device may only measure, predict, and report the relevant information of the frequency / cell in the first configuration information, or the terminal device may also measure, predict, and report the relevant information of the frequency / cell other than the frequency / cell in the first configuration information.

[0076] In some embodiments, the frequency / cell configuration may include one or more of the following: a first frequency / cell (such as a first frequency / cell list); and a second frequency / cell (such as a second frequency / cell list), wherein the second frequency / cell is associated with at least part of the first frequency / cell. The first frequency / cell configuration includes at least one cell / frequency information, and the second frequency / cell includes at least one cell / frequency configuration associated with all / part of the cells / frequencies in the first cell / frequency configuration. The association of the second frequency / cell with the first frequency / cell may, for example, mean that the second frequency / cell can form a CA / DC relationship with the first frequency / cell. Furthermore, the frequency / cell configuration may also include an association relationship between frequencies / cells, such as cell 1 being associated with cell 3.

[0077] In scenarios that support CA / DC deployment, the terminal device can obtain the cells that can form a CA / DC relationship based on the above-mentioned frequency / cell configuration, thereby determining the relevant reporting content. That is, the first reporting content may include information about the first cell and information about the second cell associated with the first cell, thereby helping the network device to provide the terminal device with appropriate primary cell configuration information and secondary cell configuration information. In addition, in the case where the network device expects the terminal device to perform primary cell group switching and secondary cell group switching, if the terminal device is not clear about which base stations / cells can form a CA / DC relationship, then the terminal device may need to report a large amount of cell information to obtain appropriate primary cell / secondary cell configuration information. Based on the above-mentioned frequency / cell configuration, the terminal device can determine the reporting content in a targeted manner, thereby helping to save signaling overhead.

[0078] In some embodiments, the first configuration information may include conditions for triggering the first report. Based on the conditions for triggering the first report, the terminal device can filter the reported content, thereby helping to avoid the signaling overhead caused by reporting all information, such as all prediction information. The following describes the conditions for triggering the first report, taking the first prediction information mentioned above as an example.

[0079] In some embodiments, the condition for triggering the first report may be associated with one or more of the channel quality of the cell, such as reference signal receiving power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR). Taking the association of the condition for triggering the first report with the RSRP threshold as an example, the condition for triggering the first report may include that the first prediction information meets a preset condition, wherein the preset condition may include one or more of the following: the predicted value of the RSRP measurement result of the first frequency point / cell is greater than or equal to the first RSRP threshold; the predicted value of the RSRP measurement result of the second frequency point / cell is greater than or equal to the second RSRP threshold; and the first time period and the second time period have a time overlap. The second frequency point / cell is associated with the first frequency point / cell, the first time period is the time when the predicted value of the RSRP measurement result of the first frequency point / cell is greater than or equal to the first RSRP threshold, and the second time period is the time when the predicted value of the RSRP measurement result of the second frequency point / cell is greater than or equal to the second RSRP threshold.

[0080] Reporting the first prediction information associated with a frequency / cell greater than the RSRP threshold helps improve the success rate of terminal devices accessing the target cell. In addition, considering the scenario of supporting CA / DC deployment, if the first time period and the second time period overlap, reporting the first prediction information associated with the first frequency / cell and the second frequency / cell helps terminal devices achieve simultaneous access to the primary cell and the primary and secondary cells.

[0081] In some embodiments, the condition for triggering the first report may be associated with time information, wherein the time information may include a predicted time period for obtaining the first prediction information and / or a time threshold, wherein the time threshold is associated with the time when the first prediction information meets the preset condition.

[0082] For example, the condition for triggering the first report may include that the first prediction information meets the preset condition within a predicted time period (such as within the future time A). Since there may be a certain time interval between the moment of the first report and the moment when the terminal device performs cell switching, reporting the relevant information of the cell that meets the preset condition within the predicted time period helps to improve the success rate of the terminal device accessing the target cell. The predicted time period may, for example, include the moment when the terminal device performs cell switching.

[0083] For another example, the condition for triggering the first report may include that the duration for which the first prediction information meets the preset condition is greater than or equal to a time threshold (which may include a first time threshold and / or a second time threshold). As an example, the condition for triggering the first report may include that the predicted value of the RSRP measurement result of the first frequency point / cell is greater than or equal to the first RSRP threshold for a duration greater than or equal to the first time threshold, and / or the predicted value of the RSRP measurement result of the second frequency point / cell is greater than or equal to the second RSRP threshold for a duration greater than or equal to the second time threshold. The above-mentioned condition for triggering the first report can, on the one hand, further improve the success rate of the terminal device accessing the target cell, and on the other hand, avoid frequent switching of the terminal device serving cell. As another example, the condition for triggering the first report may include that the duration for which the first time period and the second time period overlap is greater than or equal to a third time threshold, thereby facilitating the success rate of the terminal device accessing the primary cell and the primary and secondary cells at the same time.

[0084] For example, the conditions for triggering the first report include that the first prediction information meets the preset conditions within the prediction time period, and the duration for which the first prediction information meets the preset conditions is greater than or equal to a time threshold. As an example, the conditions for triggering the first report include that within the future time A, the predicted value of the RSRP measurement result of the first frequency point / cell is greater than or equal to the first RSRP threshold, and the duration for which the predicted value of the RSRP measurement result of the first frequency point / cell is greater than or equal to the first RSRP threshold is greater than or equal to the first time threshold. As another example, the conditions for triggering the first report include that within the future time B, the predicted value of the RSRP measurement result of the second frequency point / cell is greater than or equal to the second RSRP threshold, and the duration for which the predicted value of the RSRP measurement result of the second frequency point / cell is greater than or equal to the second RSRP threshold is greater than or equal to the second time threshold.

[0085] In some embodiments, the value of B may be greater than the value of A. In some cases, a secondary cell or a primary-secondary cell may not be able to complete access at the same time as the primary cell, but the secondary cell or the primary-secondary cell may complete access within a short period of time after the terminal device completes the primary cell handover. In this case, the value of B is greater than the value of A, which helps to improve the success rate of the terminal device accessing the secondary cell or the primary-secondary cell in the above scenario. In addition, in this case, the network device can provide the configuration information of the secondary cell or the primary-secondary cell to the terminal device, but deactivate the secondary cell or the primary-secondary cell.

[0086] In some embodiments, the condition for triggering the first report may be associated with frequency / cell priority information. Frequency / cell priority information may include, for example, one or more of the following: the priority of the first frequency / cell; the priority of the second frequency / cell; the third frequency / cell; and a priority threshold. The second frequency / cell is associated with the first frequency / cell, the third frequency / cell belongs to the first frequency / cell or the second frequency / cell, and the third frequency / cell has a higher priority than other frequencies / cells in the first or second frequency / cell. In other words, the third frequency / cell is a higher priority frequency / cell.

[0087] In some embodiments, frequency / cell priority information can be determined based on load conditions, etc. For example, when the load is heavy, or when the amount of data to be transmitted is large, frequencies / cells with larger bandwidths, or idle frequencies / cells, are given higher priority. Furthermore, frequency / cell priorities can be preconfigured or predefined fixed priorities, or they can be dynamically adjusted, for example, based on changes in load.

[0088] When the frequency / cell priority information includes the frequency / cell priority and a priority threshold, the condition for triggering the first report may include that the priority of the frequency / cell associated with the first prediction information is greater than or equal to the priority threshold. The priority threshold may, for example, be included in the first configuration information or pre-configured via other messages. For another example, the priority threshold may also be pre-defined by a protocol.

[0089] When the frequency / cell priority information includes the third frequency / cell, the condition for triggering the first report may include that the frequency / cell associated with the first prediction information belongs to the third frequency / cell. The third frequency / cell may be included in the first configuration information.

[0090] In some embodiments, the configuration granularity of the priority information may be for each frequency point or for each cell.

[0091] In some embodiments, the condition for triggering the first report may be associated with a probability threshold. The probability threshold mentioned here may be associated with the probability that the first prediction information meets the preset condition. For example, the condition for triggering the first report may include that the probability that the first prediction information meets the preset condition is greater than or equal to the probability threshold. As another example, the condition for triggering the first report may include that the probability that the first prediction information meets the preset condition within the prediction time period is greater than or equal to the probability threshold. As another example, the condition for triggering the first report may include that the probability that the duration of the first prediction information meeting the preset condition within the prediction time period is greater than or equal to the time threshold is greater than or equal to the probability threshold. The preset conditions mentioned here may include any one or more of the preset conditions mentioned above, or may be other types of preset conditions.

[0092] In some embodiments, the condition for triggering the first report may include the existence of at least one secondary cell in an activated state, or the condition for triggering the reporting of the second frequency point / cell related information may include the existence of at least one secondary cell in an activated state. If there is at least one secondary cell in an activated state, the system may operate in DC mode. At this time, reporting to the network device information associated with the second frequency point / cell that can form a DC relationship with the first frequency point / cell, such as the predicted value of the measurement result, can assist the network device in providing corresponding configuration information for the terminal device. If no secondary cell is in an activated state, the terminal device may not report the second frequency point / cell related information to the network device, thereby helping to save signaling overhead.

[0093] For the primary cell (such as the first cell) and the primary and secondary cells / secondary cells (such as the second cell), the reporting conditions for triggering the first report may be the same or different. For example, the preset conditions associated with the first cell and the preset conditions associated with the second cell may be different, such as the first RSRP threshold and the second RSRP threshold mentioned above may be different. For another example, the time information associated with the first cell and the time information associated with the second cell may be different. As an example, the predicted time period associated with the first cell and the predicted time period associated with the second cell may be different, such as the A time and the B time mentioned above. As an example, the time threshold associated with the first cell and the time threshold associated with the second cell may be different, such as the first time threshold and the second time threshold mentioned above. For another example, the priority threshold associated with the first cell and the priority threshold associated with the second cell may be different. For another example, the probability threshold associated with the first cell and the probability threshold associated with the second cell may be different.

[0094] It should be noted that for the first cell and the second cell, the reporting conditions triggering the first report may be partially the same and partially different. For example, the preset conditions associated with the first cell are different from the preset conditions associated with the second cell, but the probability threshold associated with the first cell and the probability threshold associated with the second cell may be the same.

[0095] It should be noted that the conditions for triggering the first report may include one or more of the conditions introduced above, that is, one or more of the following: the first prediction information meets the preset conditions; within the prediction time period, the first prediction information meets the preset conditions; the duration for which the first prediction information meets the preset conditions is greater than or equal to the time threshold; the probability that the first prediction information meets the preset conditions is greater than or equal to the probability threshold; the priority of the frequency / cell associated with the first prediction information is greater than or equal to the priority threshold; and the frequency / cell associated with the first prediction information belongs to the third frequency / cell.

[0096] In some embodiments, the terminal device may send first prediction information to the network device, or the network device may receive the first prediction information sent by the terminal device. The first prediction information may be determined based on the above-mentioned first configuration information. For example, the terminal device may predict the measurement results of at least one cell under at least one frequency point (such as obtaining a predicted value of the measurement result based on an AI model), and determine the first prediction information to be reported to the network device based on the predicted value of the measurement result and the first configuration information (such as the condition for triggering the first report indicated in the first configuration information).

[0097] In some embodiments, the first prediction information may include one or more of the following: a predicted value of a measurement result of a serving cell of a terminal device; a predicted value of a measurement result of a target frequency point / cell; and probability information.

[0098] The predicted value of the measurement result of the serving cell of the terminal device may include, for example, the predicted value of the measurement result within a predicted time period, such as the future time A.

[0099] The target frequency / cell may include, for example, one or more frequency points / cells among the above-mentioned first frequency points / cells, or may include one or more frequency points / cells among the above-mentioned first frequency points / cells and one or more frequency points / cells among the second frequency points / cells. Referring to Figure 10, the neighboring cells of the terminal device may include cell 1, cell 2, cell 3, cell 4 and cell 5, wherein cell 2, cell 3, cell 4 and cell 5 are associated with cell 1. The target frequency / cell may include cell 1, or may include cell 1 and cell 2, cell 3, cell 4 and cell 5. The predicted value of the target frequency / cell measurement result may include, for example, the predicted value of the measurement result of cell 1 within the future A time period, and / or the predicted value of the measurement results of cells 2 to cell 5 within the future B time period.

[0100] In some embodiments, the probability information in the first prediction information may include the probability that the target frequency / cell meets the preset conditions. The preset conditions mentioned here may be the conditions indicated by the first configuration information, such as any one or more of the preset conditions mentioned above, or other preset conditions. By reporting the probability information that the target frequency / cell meets the preset conditions, the network device can be assisted in providing the terminal device with a cell handover configuration, which helps to provide the accuracy of the configuration information.

[0101] In some embodiments, the terminal device can predict the measurement results of the terminal device's serving cell and / or neighboring cells based on the predicted information of the terminal device's movement trajectory (or the predicted movement trajectory of the terminal device). Figure 11 shows a predicted movement trajectory 1110 of the terminal device. Based on the predicted movement trajectory 1110, the terminal device can predict the measurement results of the serving cell and neighboring cells (cells 1 to 5).

[0102] In some embodiments, the first prediction information can assist the network device in releasing / adding a secondary cell, and activating / deactivating the secondary cell. For example, the first prediction information includes information associated with cells (such as the first cell and the second cell) that can establish a CA / DC relationship, and this information can assist the network device in adding / releasing the secondary cell. As an example, the first prediction information may include time information when the first cell and the second cell can establish a CA / DC relationship, and based on the time information, the network device can determine the time to add / release the secondary cell and / or the time to activate / deactivate the secondary cell. In the case where the first cell and the second cell cannot complete access at the same time (such as the second cell can only meet the access conditions after a period of time), the terminal device may complete access to the second cell after completing the first cell handover. In this case, the network device can add the second cell in advance, but deactivate the second cell. In addition, the network device can activate the second cell when the second cell meets the access conditions or before the second cell meets the access conditions.

[0103] In some embodiments, the terminal device may receive second configuration information sent by the network device, where the second configuration information includes configuration information of the candidate cell of the terminal device. For example, the second configuration information may be determined based on the first prediction information described above.

[0104] The configuration information of the candidate cells may include, for example, candidate master cell group (MCG) configuration information; and / or candidate SCG configuration information, wherein the candidate SCG is associated with at least some of the candidate MCGs.

[0105] In some embodiments, the second configuration information also includes one or more of the following: first indication information, used to instruct the terminal device to delay accessing the SCG in the candidate cell; second indication information, used to indicate the time information for the terminal device to activate and / or access the SCG in the candidate cell; and third configuration information, used to indicate the candidate cell for retaining the configuration information, and / or, the time information for activating and / or accessing the candidate cell for retaining the configuration information.

[0106] The first indication information can, for example, be used to instruct a terminal device to delay initiating random access to an SCG in a candidate cell. In some cases, such as when a secondary cell meets access conditions only after a period of time, the terminal device may not be able to access both the primary and secondary cells simultaneously. In this case, the second configuration information includes the first indication information, which helps avoid access failures caused by premature access to the secondary cell.

[0107] In some embodiments, the second indication information may include a first timer and / or a third threshold, wherein the third threshold may be associated with a predicted value of the SCG signal quality measurement result. For example, when the target SCG signal quality measurement result and / or the predicted value of the measurement result is greater than or equal to the third threshold, the target SCG is activated and / or random access is initiated to the target SCG. After the terminal device applies the target SCG configuration, when the terminal device considers the target SCG to be in a deactivated state and / or does not initiate random access to the target SCG, when the measurement result of the target SCG and / or the predicted value of the measurement result is greater than the third threshold, the target SCG is activated and / or random access is initiated to the target SCG. The third threshold mentioned here may be, for example, a third RSRP threshold. For another example, the second indication information may include a duration configuration of the first timer. As an example, when the first timer times out, the target SCG is activated and / or random access is initiated to the target SCG. After the terminal device executes conditional switching, it starts the first timer when it considers that the state of the target SCG is deactivated and / or does not initiate random access to the target, and activates the target SCG and / or initiates random access to the target SCG after the first timer expires.

[0108] In some embodiments, after the terminal device completes the conditional switching, it can retain some configuration information of the candidate cells, thereby assisting the terminal device in performing the next cell switching, which helps to avoid signaling overhead.

[0109] The third configuration information can be used, for example, to indicate the candidate cells for which configuration information is retained, or in other words, the third configuration information is used to indicate which candidate cells' configuration information is retained. As an example, the third configuration information can indicate the retained candidate cell configuration information through the index of the candidate cell configuration. Taking the second configuration information as an example, which contains 4 sets of candidate cell configurations (corresponding indexes are 1 to 4), the third configuration information can indicate the candidate cell configuration information retained by the terminal device after completing the conditional switching, such as the candidate cell configuration corresponding to the index value of 4. Accordingly, the terminal device can release the configuration information of other cells other than the candidate cells for which the configuration information is retained.

[0110] The third configuration information may include, for example, a second timer, such as a duration configuration of the second timer. The retained candidate cell configuration information may be used for the next cell handover. The second timer may be used to indicate time information for activating and / or accessing the candidate cell for which the configuration information is retained. For example, when the second timer expires, the terminal device may perform one or more of the following: applying the retained candidate cell configuration information, activating the candidate cell for which the configuration information is retained, and accessing the candidate cell for which the configuration information is retained.

[0111] The above method for a terminal device to determine the target candidate SCG related information based on the second configuration information configured by the network device is described below. The following method for a terminal device to determine the target candidate SCG related information based on the first prediction information mentioned above. The target candidate SCG related information mentioned here may include, for example, time information for activating / deactivating the target candidate SCG and / or time information for accessing the target candidate SCG.

[0112] In some embodiments, the terminal device determines whether it can access the candidate MCG and the candidate SCG at the same time (the candidate SCG is associated with at least some of the candidate MCGs) based on the first prediction information. For example, the terminal device can determine whether the terminal device at moment 3 is simultaneously in the coverage of the candidate MCG and the candidate SCG based on the first prediction information. For another example, the terminal device can determine whether the candidate MCG and the candidate SCG at moment 3 both meet the access conditions, or the time period when the candidate MCG meets the access conditions and the time period when the candidate SCG meets the access conditions based on the first prediction information. As an example, if the terminal device at moment 3 is simultaneously in the coverage of the candidate MCG and the candidate SCG, and both the candidate MCG and the candidate SCG meet the access conditions, the terminal device can simultaneously access the candidate MCG and the candidate SCG at moment 3. Otherwise, the terminal device cannot simultaneously access the candidate MCG and the candidate SCG at moment 3.

[0113] In some embodiments, if the terminal device cannot access both the candidate MCG and the candidate SCG simultaneously, the terminal device performs a first operation. The first operation includes one or more of the following: applying the configuration of the candidate MCG and the candidate SCG; deactivating the candidate SCG; delaying initiating random access to the candidate SCG; and sending third indication information to a network device corresponding to a fourth cell; wherein the fourth cell is a cell in the candidate MCG that the terminal device accesses, and the third indication information is used to indicate information associated with the candidate SCG.

[0114] For example, the terminal device cannot access the candidate MCG and the candidate SCG at the same time, but after a period of time, the candidate SCG may meet the access requirements: for example, the terminal device moves to the coverage of the candidate SCG, or the measurement result of the candidate SCG / the predicted value of the measurement result meets the execution condition of the conditional switching. In this case, the terminal device can perform the first operation. Among them, applying the configuration of the candidate MCG and the candidate SCG in advance helps to reduce the switching delay. Deactivating the candidate SCG and / or delaying the initiation of random access to the candidate SCG can avoid invalid access when the SCG does not meet the access conditions.

[0115] The third indication information may include, for example, one or more of the following: an index associated with the candidate SCG; whether to delay initiating random access to the candidate SCG; and whether to deactivate the candidate SCG. When the terminal device cannot access the candidate MCG and the candidate SCG at the same time, the terminal device sends the third indication information to the network device corresponding to the fourth cell, so that the network device and the terminal device can align and understand information related to the candidate SCG.

[0116] It should be noted that the candidate MCG and candidate SCG mentioned above can be the MCG and SCG that the terminal device intends to access, or can be replaced by the target MCG and target SCG.

[0117] In some embodiments, when the measurement result of the target SCG and / or the predicted value of the measurement result meets the access condition, the target SCG can be activated and / or random access can be initiated to the target SCG.

[0118] It should be noted that the “frequency / cell” mentioned in this application can be replaced by frequency and / or cell.

[0119] It should be noted that the method provided in the embodiment of the present application can be applied to a conditional switching process, and can also be applied to other types of cell switching processes.

[0120] In the embodiments of the present application, by introducing predicted values ​​for cell measurement results during the cell handover process, the network device can provide the terminal device with more accurate information, such as cell configuration, thereby helping to reduce the impact of mobility on system throughput. Furthermore, the network device can configure certain information for the terminal device to assist with the first report, thereby helping to improve system performance. For example, the network device can configure certain criteria for the terminal device, such as the conditions that trigger the first report, to filter the reported objects, thereby helping to reduce reporting overhead. Furthermore, considering that the terminal device is unaware of the network device's deployment method and cell accessibility, the network device can provide the terminal device with a second frequency / cell associated with the first frequency / cell, thereby assisting the terminal device in filtering the reported content, thereby helping to reduce overhead. Taking the conditional handover with a candidate secondary cell group mentioned above as an example, in the embodiments of the present application, the network device can determine whether / when the terminal device can simultaneously access the PCell and / or PSCell, or the probability of accessing different PCell & PSCell pairs, thereby providing the terminal device with more appropriate configuration information, thereby helping to increase the probability of successful access.
