For example, the transmission of the remote UE is either entirely implemented through the indirect path or entirely through the direct path. Summary of the Invention

[0003] This application provides a communication path configuration method, apparatus, and terminal, which enables a remote UE to trigger a Radio Resource Control (RRC) procedure to achieve simultaneous communication with the network side via both non-directly connected paths and directly connected paths, and can shorten the configuration time of the radio link, ensuring the robustness of the remote UE's RRC.

[0004] In a first aspect, a method for configuring a communication path is provided, comprising: a remote UE performing a first operation or a second operation on at least one of a directly connected path and a non-directly connected path; the remote UE communicating with the network side through the directly connected path and the non-directly connected path; wherein the first operation includes an establishment operation, a reconstruction operation, or a first recovery operation, the second operation includes a second recovery operation, the second recovery operation including an operation by which the remote UE recovers a non-directly connected path through the directly connected path, or an operation by which the remote UE recovers a directly connected path through the non-directly connected path.

[0005] In a second aspect, a communication path configuration apparatus is provided, comprising: an operation module for performing a first operation or a second operation on at least one of a directly connected path and a non-directly connected path; wherein the remote UE communicates with the network side through the directly connected path and the non-directly connected path; the first operation includes an establishment operation, a reconstruction operation, or a first recovery operation; the second operation includes a second recovery operation, the second recovery operation including an operation in which the remote UE recovers the non-directly connected path through the directly connected path, or an operation in which the remote UE recovers the directly connected path through the non-directly connected path.

[0026] Figure 1aThis diagram illustrates the structure of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12 (also referred to as the network side). The terminal 11 can also be called a terminal device or user equipment (UE). Terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), etc. Wearable devices include smartwatches, wristbands, headphones, glasses, etc. It should be noted that this application does not limit the specific type of terminal 11.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0027] Based on the description of the aforementioned wireless communication system, such as Figure 1b , Figure 1c , Figure 1d , Figure 1e As shown, this application also provides a schematic diagram of an SL relay communication scenario. Wherein:

[0028] Figure 1b The SL relay communication scenario shown includes at least a remote UE, a relay UE, and a base station A. The remote UE and the base station A are connected via a direct path and a non-direct path. That is, in... Figure 1bIn the given SL relay communication scenario, the remote UE can simultaneously support transmission on both the direct path and the non-direct path, and the direct path and the non-direct path can be controlled by the same base station A.

[0029] Figure 1c The SL relay communication scenario shown includes at least a remote UE, a relay UE, base station A, and base station B. A direct connection path is established between the remote UE and base station A, and a non-direct connection path is established between the remote UE and base station B. That is, in... Figure 1c In the given SL relay communication scenario, the remote UE can simultaneously support transmission on both the direct path and the non-direct path, but the direct path and the non-direct path are controlled by different base stations A and B. It should be noted that base station A and base station B can communicate with each other via the Xn interface.

[0030] As mentioned above Figure 1b The difference is, Figure 1d In the SL relay communication scenario shown, the direct connection path of the remote UE includes the MCG path and the SCG path, i.e. Figure 1d The direct connection path of the remote UE shown is dual-connection.

[0031] As mentioned above Figure 1c The difference is, Figure 1e In the SL relay communication scenario shown, the direct connection path of the remote UE includes the MCG path and the SCG path, i.e. Figure 1e The direct connection path of the remote UE shown is dual-connection.

[0032] Additionally, it is understood that the "non-direct path" mentioned in the preceding and following questions of this application refers to the radio link through which the remote UE establishes an RRC connection with the base station via the relay UE and the air interface of the relay UE; the "direct path" refers to the radio link through which the remote UE establishes an RRC connection with the base station via its own Uu interface.

[0033] Based on the description of the aforementioned wireless communication system and SL relay communication scenario, the technical solutions provided by the embodiments of this application will be further explained in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0034] like Figure 2 The diagram shown illustrates a flowchart of a communication path configuration method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a remote UE, specifically by hardware and / or software installed in the remote UE. In this embodiment, the method 200 may include at least the following steps.

[0035] S210, the remote UE performs a first operation or a second operation on at least one of the direct path and the non-direct path.

[0036] The first operation includes an establishment operation, a reconstruction operation, or a first recovery operation. That is, when the remote UE needs to establish both direct and non-direct paths simultaneously, or when at least one of the direct and / or non-direct paths supported by the remote UE fails and path recovery or reconstruction is required, the remote UE can trigger an RRC procedure to execute an establishment operation, a reconstruction operation, or a first recovery operation to establish, rebuild, or restore the direct and / or non-direct paths. This allows the remote UE to support multi-path transmission while simultaneously achieving path reconstruction and recovery under multi-path transmission. Furthermore, since the remote UE supports multi-path transmission, even if one of the multiple paths supported by the remote UE fails, transmission can continue through other valid paths, thus ensuring the RRC robustness of the remote UE.

[0037] The second operation includes a second recovery operation, which includes the remote UE recovering a non-directly connected path via a directly connected path, or the remote UE recovering a directly connected path via a non-directly connected path. That is, when the remote UE supports both directly connected and non-directly connected paths, if either the directly connected or non-directly connected path fails, the remote UE can quickly recover the failed path using the unfailed path. This effectively shortens the radio link recovery time, avoids the long radio link recovery time caused by initiating an RRC reconstruction procedure in related technologies, and improves the RRC robustness of the remote UE.

[0038] Furthermore, the remote UE communicates with the network side through both the direct connection path and the non-direct connection path. That is, through the execution of the aforementioned first or second operation, the remote UE can simultaneously communicate with the network side through both the direct connection path and the non-direct connection path. In combination with... Figure 1b and Figure 1c As shown, the network side may include one base station for simultaneously controlling non-directly connected paths and directly connected paths, or it may include two base stations for independently and simultaneously controlling non-directly connected paths and directly connected paths. This embodiment does not impose any limitations here.

[0039] In this embodiment, the remote UE performs a first operation or a second operation on at least one of the supported direct and non-direct paths. This achieves two objectives: firstly, by establishing, rebuilding, or restoring the direct and / or non-direct paths through an establishment operation, a reconstruction operation, or a first recovery operation, the remote UE can communicate with network-side devices via multiple paths. Furthermore, it supports multi-path transmission (including direct and non-direct paths) while simultaneously enabling path reconstruction and recovery under multi-path transmission, ensuring the robustness of the remote UE's RRC. Secondly, by using paths that have not failed to quickly restore failed paths, the radio link recovery time can be effectively shortened, avoiding the long radio link recovery time caused by the need to initiate an RRC reconstruction process in related technologies, thus improving the RRC robustness of the remote UE.

[0040] like Figure 3 The diagram shown illustrates a flowchart of a communication path configuration method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a remote UE, specifically by hardware and / or software installed in the remote UE. In this embodiment, the method 300 may include at least the following steps.

[0041] S310, the remote UE performs a first operation or a second operation on at least one of the direct path and the non-direct path.

[0042] The remote UE communicates with the network side through the direct connection path and the non-direct connection path.

[0043] The first operation includes an establishment operation, a reconstruction operation, or a first recovery operation. The second operation includes a second recovery operation, which includes the operation of the remote UE restoring a non-directly connected path through a direct path, or the operation of the remote UE restoring a direct path through a non-directly connected path.

[0044] It is understood that, in addition to referring to the relevant description in method embodiment 200, the implementation process of S310 can also be described again as a possible implementation method. Figure 3 The process by which the remote UE performs the first operation on at least one of the direct path and the non-direct path can be implemented by S311, as follows.

[0045] S311, the remote UE performs a first operation on at least one of the direct path and the non-direct path when it determines at least one first cell and / or at least one first relay UE.

[0046] The remote UE communicates with the network side through the direct connection path and the non-direct connection path.

[0047] The at least one first cell is a cell obtained by the remote UE through a cell selection or reselection procedure and that meets the cell selection or reselection conditions, i.e., a suitable cell; correspondingly, the at least one first relay UE is a relay UE obtained by the remote UE through a relay selection or reselection procedure and that meets the relay selection or reselection conditions, i.e., a suitable relay UE.

[0048] Based on this, the process by which the remote UE performs an establishment operation on at least one of the direct path and non-direct path based on at least one first cell and / or at least one first relay UE may include the following (11) and / or (12), the contents of which are as follows.

[0049] (11) The remote UE establishes the direct connection path based on the RRC connection establishment procedure initiated by the target cell. Wherein, the target cell is one of the at least one first cell.

[0050] For example, the remote UE can first select the target cell from the at least one first cell, and then initiate an RRC connection establishment process based on the target cell to establish a direct connection path with the first target base station to which the target cell belongs.

[0051] It is understood that the remote UE may select the target cell from the at least one first cell in a random manner, or select it according to the performance of the first cell, etc., and there are no restrictions here.

[0052] (12) The remote UE establishes the non-directly connected path based on the RRC connection establishment procedure initiated by the target relay UE. The target relay UE is one of the at least one first relay UE.

[0053] For example, the remote UE can first select the target relay UE from the at least one first relay UE, and then initiate an RRC connection establishment process based on the relay UE to establish a non-direct connection path with the second target base station to which the target relay UE belongs.

[0054] Similar to the selection of the target cell, the remote UE may select the target relay UE from the at least one first relay UE in a random manner, or according to the performance of the first relay UE, etc., without any restrictions.

[0055] Furthermore, the first target base station mentioned in (11) and the second target base station mentioned in (12) can be the same or different. That is, the direct connection path and the non-direct connection path can be controlled by the same base station or independently controlled by different base stations. For example, Figure 1b and Figure 1c As shown in the image.

[0056] Furthermore, the process by which the remote UE performs a reconstruction operation on at least one of the direct path and the non-direct path based on at least one first cell and / or at least one first relay UE may include the following (13) and / or (14), the contents of which are as follows.

[0057] (13) The remote UE reconstructs the direct connection path based on the RRC connection reconstruction procedure initiated by the target cell. Wherein, the target cell is one of the at least one first cell.

[0058] For example, the remote UE can first select the target cell from the at least one first cell, and then initiate an RRC connection reconstruction process based on the target cell to reconstruct the direct connection path with the first target base station to which the target cell belongs.

[0059] (14) The remote UE reconstructs the non-directly connected path based on the RRC connection reconstruction procedure initiated by the target relay UE. The target relay UE is one of the at least one first relay UE.

[0060] For example, the remote UE can first select the target relay UE from the at least one first relay UE, and then initiate an RRC connection reconstruction process based on the relay UE to reconstruct the non-directly connected path with the second target base station to which the target relay UE belongs.

[0061] Furthermore, the process by which the remote UE performs a first recovery operation on at least one of the direct path and non-direct path based on at least one first cell and / or at least one first relay UE may include the following (15) and / or (16), the contents of which are as follows.

[0062] (15) The remote UE restores the direct connection path based on the RRC connection recovery procedure initiated by the target cell; wherein the target cell is one of the at least one first cell.

[0063] For example, the remote UE can first select the target cell from the at least one first cell, and then initiate an RRC connection recovery process based on the target cell to establish a direct connection path with the first target base station to which the target cell belongs, thereby realizing the recovery of the direct connection path.

[0064] (16) The remote UE restores the non-directly connected path based on the RRC procedure initiated by the target relay UE. The target relay UE is one of the at least one first relay UE.

[0065] For example, the remote UE can first select the target relay UE from the at least one first relay UE, and then initiate an RRC connection recovery procedure based on the relay UE to rebuild the non-directly connected path with the second target base station to which the target relay UE belongs, thereby realizing the recovery of the non-directly connected path.

[0066] It should be noted that the relevant descriptions of the selection of target cell, target relay UE, first target base station and second target base station involved in (13)-(16) can be referred to the relevant descriptions in (11)-(12) above. To avoid repetition, they will not be repeated here.

[0067] In addition, in the aforementioned (11)-(16), for scenarios where the first operation needs to be performed on both the direct path and the non-direct path, this embodiment does not restrict the order of operation of the direct path and the non-direct path. For example, the remote UE can first establish / restore the direct path and then establish / restore the non-direct path; or it can first establish / restore the non-direct path and then establish / restore the direct path, etc.

[0068] Of course, in addition to the operation methods (such as establishment, reconstruction, and restoration) for direct and non-direct paths given above, if the terminal has already established a direct path (such as the direct path supported by the remote UE has not failed, or the remote UE has completed the establishment, reconstruction, or restoration of the direct path based on the aforementioned (11), (13), and (15), then the remote UE can directly establish, rebuild, or restore the non-direct path based on the direct path, thereby improving the configuration efficiency of the non-direct path, shortening the configuration time of the non-direct path, and enhancing the RRC robustness of the remote UE.

[0069] For example, assuming that the UE has completed the establishment, reconstruction or restoration of the direct path based on the aforementioned (11), (13) and (15), that is, when the remote UE performs the first operation on the direct path based on the target cell, the remote UE can further perform the first operation on the non-direct path, such as establishment, reconstruction or restoration, by performing the following (21)-(23).

[0070] (21) The remote UE may receive the first RRC reconfiguration message or the first RRC recovery message sent by the first target base station.

[0071] The first target base station is the base station to which the target cell belongs.

[0072] The first RRC reconfiguration message includes at least the configuration information of the second relay UE for the establishment or reconstruction of the non-directly connected path, and the first RRC recovery message includes at least the configuration information of the second relay UE for the recovery of the non-directly connected path.

[0073] In one implementation, the second relay UE can be selected by the first target base station from its cached relay UEs, or it can be selected based on at least one third relay UE reported by the remote UE, or it can be selected by combining the relay UEs it has cached and at least one first and third relay UE reported by the remote UE. This embodiment does not impose any restrictions here.

[0074] In other words, before receiving the first RRC reconfiguration message or the first RRC recovery message sent by the first target base station, the remote UE may report relevant information of at least one third relay UE to the first target base station for the first target relay UE to select the second relay UE.

[0075] Optionally, the at least one third relay UE includes at least one of the following (211)-(212).

[0076] (211) At least partially the first relay UE.

[0077] (212) The remote UE is at least one fourth relay UE determined according to the measurement configuration of the first target base station and satisfying the first measurement reporting event. The first measurement reporting event can be implemented by protocol agreement, higher layer configuration or network side configuration, and is not limited here.

[0078] In addition, the relevant information of the at least one third relay UE may include at least one of the following (213)-(214).

[0079] (213) Identification information of at least one of the third relay UEs.

[0080] (214) PC5 path quality information between the remote UE and at least one of the third relay UEs.

[0081] (22) Based on the configuration information of the second relay UE, the remote UE sends a first RRC reconfiguration completion message or a first RRC recovery completion message to the first target base station through the second relay UE.

[0082] (23) When the first RRC reconfiguration completion message or the first RRC recovery completion message is successfully sent to the first target base station, the remote UE establishes the non-direct path with the first target base station through the second relay UE.

[0083] Of course, it should be noted that in this implementation, the direct connection path and the non-direct connection path are controlled by the same first target base station.

[0084] In addition, please refer to Figure 1dand 1e If the direct path supported by the remote UE is dual connectivity (DC), that is, the direct path includes a Master cell group (MCG) path and a Secondary Cell Group (SCG) path, then, assuming the aforementioned direct path is an MCG path, the first RRC reconfiguration message or the first RRC recovery message may also include the configuration information of the third target base station (which can be understood as: SN configuration or SCG configuration), and the remote UE establishes the SCG path based on the configuration information of the third target base station.

[0085] Furthermore, corresponding to the aforementioned establishment of non-directly connected paths based on direct paths, if the terminal has already established a non-directly connected path (e.g., the non-directly connected path supported by the remote UE has not failed, or the remote UE has completed the establishment, reconstruction, or recovery of the non-directly connected path based on the aforementioned (12), (14), (16), then the remote UE can directly establish, reconstruct, or recover the direct path based on the non-directly connected path, thereby improving the configuration efficiency of the direct path, shortening the configuration time of the direct path, and enhancing the RRC robustness of the remote UE.

[0086] For example, assuming that the UE has completed the establishment, reconstruction or restoration of the non-directly connected path based on the aforementioned (12), (14) and (16), that is, when the remote UE performs the first operation on the non-directly connected path based on the target relay UE, the remote UE can further perform the first operation on the non-directly connected path, such as establishment, reconstruction or restoration, by performing the following (24)-(26).

[0087] (24) The remote UE receives the second RRC reconfiguration message or the second RRC recovery message sent by the second target base station.

[0088] The second target base station is the base station to which the target relay UE belongs.

[0089] The second RRC reconfiguration message includes at least the configuration information of the second cell for the establishment or reconstruction of the direct path, and the second RRC recovery message includes at least the configuration information of the second cell for the recovery of the direct path.

[0090] In one implementation, the second cell can be selected by the second target base station from its cached relay UEs, or it can be selected based on at least one third cell reported by the remote UE, or it can be selected by combining the cell information cached by the base station and at least one third cell reported by the remote UE. This embodiment does not impose any restrictions on this.

[0091] In other words, before receiving the second RRC reconfiguration message or the second RRC recovery message sent by the second target base station, the remote UE may report relevant information of at least one third cell to the second target base station for the second target relay UE to select the second cell.

[0092] Optionally, the at least one third cell may include at least one of the following (241)-(242).

[0093] (241) At least partially the first cell.

[0094] (242) The remote UE determines at least one fourth cell based on the measurement configuration of the second target base station and satisfies the second measurement reporting event.

[0095] In addition, the relevant information of the at least one third cell may include at least one of the following (243)-(244).

[0096] (243) Identification information of at least one of the third cells.

[0097] (244) Uu path quality information between the remote UE and at least one of the third cells.

[0098] (25) Based on the configuration information of the second cell, the remote UE sends a second RRC reconfiguration completion message or a second RRC recovery completion message to the second target base station through the second cell.

[0099] (26) When the second RRC reconfiguration completion message or the second RRC recovery completion message is successfully sent to the second target base station, the remote UE establishes the direct connection path with the second target base station.

[0100] Of course, it should be noted that in this implementation, the direct connection path and the non-direct connection path are controlled by the same second target base station.

[0101] In addition, please refer to the following: Figure 1d and 1e If the direct path supported by the remote UE is DC, that is, the direct path includes MCG path and SCG path, then, assuming that the aforementioned direct path is MCG path, the second RRC reconfiguration message or the second RRC recovery message may also include the configuration information of the fourth target base station (which can be understood as: SN configuration or SCG configuration), and the remote UE establishes the SCG path based on the configuration information of the fourth target base station.

[0102] like Figure 4The diagram shown illustrates a flowchart of a communication path configuration method 400 provided in an exemplary embodiment of this application. This method 400 can be executed by, but is not limited to, a remote UE, specifically by hardware and / or software installed in the remote UE. In this embodiment, the method 400 may include at least the following steps.

[0103] S410, the remote UE performs a first operation or a second operation on at least one of the direct path and the non-direct path.

[0104] The remote UE communicates with the network side through the direct connection path and the non-direct connection path.

[0105] The first operation includes an establishment operation, a reconstruction operation, or a first recovery operation. The second operation includes a second recovery operation, which includes the operation of the remote UE restoring a non-directly connected path through a direct path, or the operation of the remote UE restoring a direct path through a non-directly connected path.

[0106] It is understood that, in addition to referring to the relevant descriptions in method embodiments 200 and / or 300, the implementation process of S410 can also be referred to again. Figure 4 As one possible implementation, the step of the remote UE performing a first operation or a second operation on at least one of the direct path and the non-direct path can be implemented by S411 and S412, as follows.

[0107] S411, the remote UE determines the first information.

[0108] The first information includes at least one of the following (31)-(32).

[0109] (31) Whether the direct connection path meets the direct connection path failure condition.

[0110] Optionally, the direct path failure condition includes at least one of the following (311)-(312).

[0111] (311) The remote UE experienced a Uu wireless link failure.

[0112] (312) The remote UE experienced a Uu wireless link recovery failure.

[0113] (32) Whether the non-directly connected path meets the non-directly connected path failure condition.

[0114] Optionally, the failure condition of the non-directly connected path may include at least one of the following (321)-(323).

[0115] (321) A PC5 wireless link failure occurred between the remote UE and the relay UE.

[0116] (322) The PC5 radio link is released between the remote UE and the relay UE.

[0117] (323) The remote UE receives the first indication information of the relay UE. The first indication information is sent by the relay UE when a first condition is met. The first condition includes at least one of the following: the relay UE experiences a Uu radio link failure, the relay UE experiences a Uu radio link recovery failure, the relay UE experiences a Uu handover, and the relay UE experiences a Uu handover failure.

[0118] In this embodiment, the first information, the direct connection path failure condition, and the non-direct connection path failure condition can all be implemented by protocol agreement, higher layer configuration, or network side configuration, and no restrictions are imposed here.

[0119] S412, the remote UE performs the first operation or the second operation on at least one of the direct path and the non-direct path according to the first information.

[0120] In one possible implementation, the step of the remote UE performing the first operation or the second operation on at least one of the direct path and the non-direct path according to the first information may include any one of the following (41)-(43).

[0121] (41) If the direct path meets the direct path failure condition and the non-direct path does not meet the non-direct path failure condition, the remote UE performs the operation of restoring the direct path through the non-direct path.

[0122] In one implementation, the process by which the remote UE restores the direct path through the non-direct path can be referred to the relevant description of the remote UE restoring the direct path based on the non-direct path in the aforementioned method embodiment 300. To avoid repetition, it will not be repeated here.

[0123] In another implementation, the remote UE may also determine the method of restoring the direct path based on whether the fifth target base station corresponding to the non-directly connected path supports the RRC procedure for restoring the direct path through the non-directly connected path, as described in (411) and (412) below. It can be understood that in this embodiment, the remote UE may determine whether the fifth target base station supports the RRC procedure for restoring the direct path through the non-directly connected path based on whether a first timer is configured. If the first timer is configured, it is determined that the fifth target base station supports the RRC procedure for restoring the direct path through the non-directly connected path; otherwise, it does not. The first timer is used to indicate the effective duration of the RRC procedure for restoring the direct path through the non-directly connected path by the remote UE. Furthermore, all timers mentioned in the context of this application can be configured by the base station (such as broadcast signaling configuration or RRC-specific signaling configuration) and run on the remote UE.

[0124] (411) If the fifth target base station corresponding to the non-directly connected path supports the RRC procedure of restoring the direct path through the non-directly connected path, the remote UE performs the operation of restoring the direct path through the non-directly connected path.

[0125] The process of restoring the direct path through the non-direct path may include the following (4111)-(4113), the contents of which are as follows.

[0126] (4111) The remote UE reports the direct path failure message corresponding to the direct path to the fifth target base station corresponding to the non-direct path, and starts the first timer.

[0127] (4112) When the remote UE receives the third RRC reconfiguration message sent by the fifth target base station, it stops the first timer. The third RRC reconfiguration message includes at least the configuration information of a fifth cell. The configuration information of the fifth cell is used to instruct the remote UE to establish the direct connection path with the sixth target base station to which the fifth cell belongs.

[0128] Optionally, the configuration information of the fifth cell can be determined by the fifth target base station based on its cached cell information, or it can be determined based on the cell information reported by the remote UE. No restriction is imposed here.

[0129] It should be noted that the fifth target base station corresponding to the non-directly connected path and the sixth target base station to which the fifth cell belongs may be the same or different. Of course, if the fifth target base station is different from the sixth target base station, the configuration information of the fifth cell included in the third RRC reconfiguration message may be generated by the sixth target base station and then sent to the fifth target base station.

[0130] Furthermore, depending on the communication scenario, the fifth target base station may be the same as or different from the first or second target base station described in the aforementioned method embodiments. Correspondingly, the sixth target base station may be the same as or different from the aforementioned first or second target base station.

[0131] (4113) If the first timer times out, the remote UE performs the reconstruction operation to rebuild the direct path.

[0132] (412) If the fifth target base station corresponding to the non-directly connected path does not support the RRC procedure of restoring the directly connected path through the non-directly connected path, the remote UE performs the reconstruction operation to reconstruct the directly connected path.

[0133] It should be noted that the reconstruction operations described in (4113) and (412) can be referred to the relevant descriptions in the aforementioned method embodiments 200 and / or 300. To avoid repetition, they will not be repeated here.

[0134] (42) If the direct path does not meet the direct path failure condition, and the non-direct path meets the non-direct path failure condition, the remote UE performs the operation of restoring the non-direct path through the direct path.

[0135] In one implementation, the process by which the remote UE recovers the non-directly connected path through the direct path can be referred to the relevant description of the remote UE recovering the non-directly connected path based on the direct path in the aforementioned method embodiment 300. To avoid repetition, it will not be repeated here.

[0136] In another implementation, the remote UE may also determine the method of restoring the non-directly connected path based on whether the seventh target base station corresponding to the direct path supports the RRC procedure for restoring the non-directly connected path through the direct path, as described in (421) and (422) below. It can be understood that in this embodiment, the remote UE may determine whether the seventh target base station supports the RRC procedure for restoring the non-directly connected path through the direct path based on whether a second timer is configured. If the second timer is configured, it is determined that the seventh target base station supports the RRC procedure for restoring the non-directly connected path through the direct path; otherwise, it does not. The second timer is used to indicate the effective duration of the RRC procedure for restoring the non-directly connected path through the direct path for the remote UE.

[0137] (421) If the seventh target base station corresponding to the direct path supports the RRC procedure of restoring the non-direct path through the direct path, the remote UE performs the operation of restoring the non-direct path through the direct path.

[0138] The process of restoring the non-directly connected path through the direct path may include the following (4211)-(4213).

[0139] (4211) The remote UE reports the non-direct path failure message corresponding to the non-direct path to the seventh target base station corresponding to the direct path, and starts the second timer.

[0140] (4212) When the remote UE receives the fourth RRC reconfiguration message sent by the seventh target base station, it stops the second timer. The fourth RRC reconfiguration message includes at least the configuration information of a fifth relay UE, wherein the configuration information of the fifth relay UE is used to instruct the remote UE to establish the non-direct path with the eighth target base station to which the fifth relay UE belongs.

[0141] Optionally, the configuration information of the fifth relay UE can be determined by the seventh target base station based on the relay UE information it caches, or it can be determined based on the relay UE information reported by the remote UE. No restriction is imposed here.

[0142] It should be noted that the seventh target base station corresponding to the direct connection path and the eighth target base station to which the fifth relay UE belongs may be the same or different. Of course, if the seventh target base station is different from the eighth target base station, the configuration information of the fifth relay UE included in the fourth RRC reconfiguration message may be generated by the eighth target base station and then sent to the seventh target base station.

[0143] Furthermore, depending on the communication scenario, the seventh target base station may be the same as or different from the first target base station or the second target base station mentioned in the aforementioned method embodiments. Correspondingly, the eighth target base station may be the same as or different from the aforementioned first target base station or the second target base station.

[0144] (4213) If the second timer times out, the remote UE performs the reconstruction operation to reconstruct the non-directly connected path.

[0145] (422) If the seventh target base station corresponding to the direct path does not support the RRC procedure of restoring the non-direct path through the direct path, the remote UE performs the reconstruction operation to reconstruct the non-direct path.

[0146] It should be noted that the reconstruction operations described in (4213) and (422) can be referred to the relevant descriptions in the aforementioned method embodiments 200 and / or 300. To avoid repetition, they will not be repeated here.

[0147] (43) If the direct path meets the direct path failure condition and the non-direct path meets the non-direct path failure condition, the remote UE performs the reconstruction operation.

[0148] The relevant description of the reconstruction operation can be referred to in the relevant descriptions in the aforementioned method embodiments 200 and / or 300. To avoid repetition, it will not be repeated here.

[0149] In this embodiment, the remote UE restores the corresponding path by either restoring the non-directly connected path through the direct path or restoring the direct path through the non-directly connected path, based on the first information. This effectively shortens the path restoration time and improves the RRC robustness of the remote UE.

[0150] like Figure 5 The diagram shown illustrates a flowchart of a communication path configuration method 500 provided in an exemplary embodiment of this application. This method 500 can be executed by, but is not limited to, a remote UE, specifically by hardware and / or software installed in the remote UE. In this embodiment, the method 500 may include at least the following steps.

[0151] S510, the remote UE performs a first operation or a second operation on at least one of the direct path and the non-direct path.

[0152] The remote UE communicates with the network side through the direct connection path and the non-direct connection path.

[0153] The first operation includes an establishment operation, a reconstruction operation, or a first recovery operation. The second operation includes a second recovery operation, which includes the operation of the remote UE restoring a non-directly connected path through a direct path, or the operation of the remote UE restoring a direct path through a non-directly connected path.

[0154] It is understood that, in addition to referring to the relevant descriptions in method embodiments 200, 300, and 400, the implementation process of S510 can be implemented in one possible way. In this case, the direct connection path of the remote UE is dual-connection (DC), that is, the direct connection path may include an MCG path and an SCG path. Correspondingly, the second operation may include the operation of the remote UE restoring the SCG path through the MCG path, or the operation of the remote UE restoring the MCG path through the SCG path, or the operation of the remote UE restoring the non-direct connection path through the MCG path, or the operation of the remote UE restoring the non-direct connection path through the SCG path, or the operation of the remote UE restoring the MCG path through the non-direct connection path, or the operation of the remote UE restoring the SCG path through the non-direct connection path.

[0155] In this case, please refer to [the relevant documentation] again. Figure 5 The steps by which the remote UE performs a first operation or a second operation on at least one of the direct path and the non-direct path may include S511 and S512, as follows.

[0156] S511, the remote UE determines the second information.

[0157] Optionally, the second information includes at least one of the following (51)-(53).

[0158] (51) Whether the MCG path meets the MCG path failure condition.

[0159] The failure conditions of the MCG path include at least one of the following (511)-(512).

[0160] (511) The remote UE experienced a Uu wireless link failure.

[0161] (512) The remote UE experienced a Uu wireless link recovery failure.

[0162] (52) Whether the SCG path meets the SCG path failure conditions.

[0163] The SCG path failure condition includes: the remote UE experiencing an SCG failure.

[0164] (53) Whether the non-directly connected path meets the non-directly connected path failure condition.

[0165] The failure condition of the non-directly connected path may include at least one of the following (531)-(533).

[0166] (531) A PC5 wireless link failure occurred between the remote UE and the relay UE.

[0167] (532) The PC5 radio link is released between the remote UE and the relay UE.

[0168] (533) The remote UE receives a first indication information from the relay UE. The first indication information is sent by the relay UE when a first condition is met. The first condition includes at least one of the following: the relay UE experiences a Uu radio link failure, the relay UE experiences a Uu radio link recovery failure, the relay UE experiences a Uu handover, and the relay UE experiences a Uu handover failure.

[0169] It is understood that the second information, the MCG path failure condition, and the non-directly connected path failure condition can be agreed upon by the protocol, configured by higher layers, or configured by network-side devices, and no restrictions are imposed here.

[0170] S512, the remote UE performs the first operation or the second operation on at least one of the MCG path, SCG path and non-directly connected path according to the second information.

[0171] In one implementation, the steps of the remote UE performing a first operation or a second operation on at least one of the direct path and the non-direct path according to the second information include any one of the following (61)-(67).

[0172] (61) If the MCG path meets the failure condition, the SCG path meets the failure condition, and the non-directly connected path does not meet the failure condition, the remote UE performs the step of restoring the MCG path through the non-directly connected path, and / or the remote UE performs the operation of restoring the SCG path through the non-directly connected path.

[0173] In this embodiment, when the remote UE performs the operation of restoring the MCG path through the non-directly connected path, the remote UE can determine the method of restoring the MCG path based on whether the ninth target base station corresponding to the non-directly connected path supports the RRC procedure for restoring the MCG path through the non-directly connected path, as described in (611) and (612) below. It can be understood that in this embodiment, the remote UE can determine whether the ninth target base station supports the RRC procedure for restoring the MCG path through the non-directly connected path based on whether a third timer is configured. If the third timer is configured, it is determined that the ninth target base station supports the RRC procedure for restoring the MCG path through the non-directly connected path; otherwise, it does not. The third timer is used to indicate the effective duration of the RRC procedure for restoring the MCG path through the non-directly connected path by the remote UE.

[0174] (611) If the ninth target base station corresponding to the non-directly connected path supports the RRC procedure of restoring the MCG path through the non-directly connected path, the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0175] The process by which the remote UE restores the MCG path through the non-direct connection path may include the following (6111)-(6113), the contents of which are as follows.

[0176] (6111) The remote UE reports the MCG direct connection failure message corresponding to the MCG path to the ninth target base station corresponding to the non-direct connection path, and starts the third timer.

[0177] (6112) When the remote UE receives the fifth RRC reconfiguration message sent by the ninth target base station, it stops the third timer. The fifth RRC reconfiguration message includes configuration information of at least one sixth cell, wherein the configuration information of the sixth cell is used to instruct the remote UE to establish the MCG path with the tenth target base station to which the sixth cell belongs.

[0178] Optionally, the configuration information of the sixth cell can be determined by the ninth target base station based on its cached cell information, or it can be determined based on the cell information reported by the remote UE. No restriction is imposed here.

[0179] It should be noted that the ninth target base station corresponding to the non-directly connected path may be the same as or different from the tenth target base station to which the sixth cell belongs. Of course, if the ninth target base station is different from the tenth target base station, the configuration information of the sixth cell included in the fifth RRC reconfiguration message may be generated by the tenth target base station and then sent to the ninth target base station.

[0180] (6113) If the third timer times out, the remote UE performs the reconstruction operation to reconstruct the MCG path.

[0181] (612) If the ninth target base station corresponding to the non-directly connected path does not support the RRC procedure for restoring the MCG path through the non-directly connected path, the remote UE performs the reconstruction operation to reconstruct the MCG path.

[0182] It should be noted that the reconstruction operations described in (6113) and (612) can refer to the relevant descriptions of the reconstruction of the direct connection path in the aforementioned method embodiments 200-400. To avoid repetition, they will not be repeated here.

[0183] Furthermore, depending on the communication scenario, the ninth target base station may be the same as or different from the first target base station or the second target base station described in the aforementioned method embodiments. Correspondingly, the tenth target base station may be the same as or different from the aforementioned first target base station or the second target base station.

[0184] Furthermore, when the remote UE performs the operation of restoring the SCG path through the non-directly connected path, the remote UE can determine the method of restoring the SCG path based on whether the target base station corresponding to the non-directly connected path supports the RRC procedure for restoring the SCG path through the non-directly connected path, as described in (613) and (614) below. It can be understood that in this embodiment, the remote UE can determine whether the ninth target base station supports the RRC procedure for restoring the SCG path through the non-directly connected path based on whether a sixth timer is configured. If the sixth timer is configured, it is determined that the ninth target base station supports the RRC procedure for restoring the SCG path through the non-directly connected path; otherwise, it does not. The sixth timer is used to indicate the effective duration of the RRC procedure for restoring the SCG path through the non-directly connected path by the remote UE.

[0185] (613) If the ninth target base station corresponding to the non-directly connected path supports the RRC procedure of restoring the MCG path through the non-directly connected path, the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0186] Optionally, the process by which the remote UE recovers the SCG path through the non-directly connected path may include the following (6131)-(6133), the contents of which are as follows.

[0187] (6131) The remote UE reports the SCG direct connection failure message corresponding to the SCG path to the ninth target base station corresponding to the non-direct connection path, and starts the sixth timer.

[0188] (6132) When the remote UE receives the fifth RRC reconfiguration message sent by the ninth target base station, it stops the sixth timer. The fifth RRC reconfiguration message includes configuration information of at least one sixth cell, wherein the configuration information of the sixth cell is used to instruct the remote UE to establish the SCG path with the fifteenth target base station to which the sixth cell belongs.

[0189] Optionally, the configuration information of the sixth cell can be determined by the ninth target base station based on its cached cell information, or it can be determined based on the cell information reported by the remote UE. No restriction is imposed here.

[0190] It should be noted that the ninth target base station corresponding to the non-directly connected path may be the same as or different from the fifteenth target base station to which the sixth cell belongs. Of course, if the ninth target base station is different from the fifteenth target base station, the configuration information of the sixth cell included in the fifth RRC reconfiguration message may be generated by the fifteenth target base station and then sent to the ninth target base station.

[0191] (6133) If the sixth timer times out, the remote UE performs the reconstruction operation to reconstruct the SCG path.

[0192] (614) If the ninth target base station corresponding to the non-directly connected path does not support the RRC procedure for restoring the SCG path through the non-directly connected path, the remote UE performs the reconstruction operation to reconstruct the SCG path.

[0193] It should be noted that the reconstruction operations described in (6133) and (614) can refer to the relevant descriptions of the reconstruction of the direct connection path in the aforementioned method embodiments 200 and / or 300. To avoid repetition, they will not be repeated here.

[0194] Furthermore, depending on the communication scenario, the ninth target base station may be the same as or different from the first target base station or the second target base station mentioned in the aforementioned method embodiments. Correspondingly, the fifteenth target base station may be the same as or different from the aforementioned first target base station or the second target base station.

[0195] (62) If the MCG path meets the failure condition of the MCG path, the SCG path does not meet the failure condition of the SCG path, and the non-directly connected path does not meet the failure condition of the non-directly connected path, the remote UE performs the operation of restoring the MCG path through the SCG path, or the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0196] The operation of restoring the MCG path through the SCG path performed by the remote UE can refer to the existing MCG recovery process, and this application does not limit it.

[0197] In addition, the implementation process of the remote UE performing the operation of restoring the MCG path through the non-direct path can be referred to the relevant descriptions in (611)-(612) above, and will not be repeated here to avoid repetition.

[0198] Furthermore, in a scenario where the MCG path meets the MCG path failure condition, the SCG path does not meet the SCG path failure condition, and the non-directly connected path does not meet the non-directly connected path failure condition, the remote UE determines the method for restoring the MCG path based on one of the following: random selection, network configuration, or protocol specification.

[0199] For example, assuming the network is configured with third information, the remote UE can determine whether to restore the MCG path via the SCG path or via the non-directly connected path based on the third information configured in the network.

[0200] The third information may include at least one of the following (621)-(625).

[0201] (623) Second indication information, the second indication information is used to indicate to the remote UE whether to restore the MCG path through the SCG path or through the non-direct path.

[0202] The second indication information may be a 1-bit indication information configured by the network, and there is no limitation on it.

[0203] (624) First threshold, the first threshold is the Uu link quality threshold of the SCG path.

[0204] It should be noted that the link quality mentioned in this application can be determined based on parameters such as reference signal received power (RSRP).

[0205] (625) Second threshold, the second threshold is the PC5 link quality threshold of the non-directly connected path.

[0206] Based on this, the step of the remote UE determining whether to restore the MCG path through the SCG path or through the non-directly connected path according to the Uu link quality of the SCG path and / or the PC5 link quality of the non-directly connected path includes any one of (6251)-(6256).

[0207] (6251) Assuming the network is configured with the first threshold, then, if the Uu link quality of the SCG path meets the first threshold, the remote UE performs the operation of restoring the MCG path through the SCG path.

[0208] (6252) Assuming the network is configured with the first threshold, if the quality of the Uu link of the SCG path does not meet the first threshold, the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0209] (6253) Assuming the network is configured with the second threshold, then, if the PC5 link quality of the non-directly connected path meets the second threshold, the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0210] (6254) Assuming the network is configured with the second threshold, then, if the quality of the PC5 link of the non-directly connected path does not meet the second threshold, the remote UE performs the operation of restoring the MCG path through the SCG path;

[0211] (6255) Assuming the network is configured with the first threshold and the second threshold, then, if the Uu link quality of the SCG path meets the first threshold and the PC5 link quality of the non-directly connected path does not meet the second threshold, the remote UE performs the operation of restoring the MCG path through the SCG path.

[0212] (6256) Assuming the network is configured with the first threshold and the second threshold, if the quality of the Uu link of the SCG path does not meet the first threshold and the quality of the PC5 link of the non-directly connected path meets the second threshold, the remote UE performs the operation of restoring the MCG path through the non-directly connected path.

[0213] (63) If the MCG path meets the failure condition of the MCG path, the SCG path does not meet the failure condition of the SCG path, and the non-directly connected path meets the failure condition of the non-directly connected path, the remote UE performs the operation of restoring the MCG path through the SCG path, and / or the remote UE performs the operation of restoring the non-directly connected path through the SCG path.

[0214] It is understood that the implementation process of the remote UE performing the operation of restoring the MCG path through the SCG path can be referred to the relevant description in (62). To avoid repetition, it will not be repeated here.

[0215] Furthermore, when the remote UE performs the operation of restoring the non-directly connected path through the SCG path, the remote UE can determine the method of restoring the non-directly connected path based on whether the thirteenth target base station corresponding to the SCG path supports the RRC procedure for restoring the non-directly connected path through the SCG path, as described in (631) and (632) below. It can be understood that in this embodiment, the remote UE can determine whether the thirteenth target base station supports the RRC procedure for restoring the non-directly connected path through the SCG path based on whether a fifth timer is configured. If the fifth timer is configured, it is determined that the thirteenth target base station supports the RRC procedure for restoring the non-directly connected path through the SCG path; otherwise, it does not. The fifth timer is used to indicate the effective duration of the RRC procedure for the remote UE to restore the non-directly connected path through the SCG path.

[0216] (631) If the thirteenth target base station corresponding to the SCG path supports the recovery of the non-directly connected path through the SCG path, the remote UE performs the operation of recovering the non-directly connected path through the SCG path.

[0217] Optionally, the process by which the remote UE restores the non-directly connected path through the SCG path may include the following (6311)-(6133), the contents of which are as follows.

[0218] (6311) The remote UE reports the non-direct path failure message corresponding to the non-direct path to the thirteenth target base station corresponding to the SCG path, and starts the fifth timer.

[0219] (6312) When the remote UE receives the sixth RRC reconfiguration message sent by the thirteenth target base station corresponding to the SCG path, it stops the fifth timer. The sixth RRC reconfiguration message includes at least the configuration information of an eighth relay UE, wherein the configuration information of the eighth relay UE is used to instruct the remote UE to establish a non-direct path with the fourteenth target base station to which the eighth relay UE belongs.

[0220] Optionally, the configuration information of the eighth relay UE can be determined by the thirteenth target base station based on its cached relay UE information, or it can be determined based on the relay UE information reported by the remote UE. No restriction is imposed here.

[0221] It should be noted that the thirteenth target base station corresponding to the non-directly connected path and the fourteenth target base station to which the eighth relay UE belongs may be the same or different. Of course, if the thirteenth target base station is different from the fourteenth target base station, the configuration information of the eighth relay UE included in the sixth RRC reconfiguration message may be generated by the fourteenth target base station and then sent to the thirteenth target base station.

[0222] (6313) If the fifth timer times out, the remote UE performs the reconstruction operation to restore the non-directly connected path.

[0223] (632) If the thirteenth target base station corresponding to the SCG path does not support the recovery of the non-directly connected path through the SCG path, the remote UE performs the reconstruction operation to recover the non-directly connected path.

[0224] It should be noted that the reconstruction operations described in (6313) and (632) can refer to the relevant descriptions of the reconstruction of the non-directly connected path in the aforementioned method embodiments 200 and / or 300. To avoid repetition, they will not be repeated here.

[0225] Furthermore, depending on the communication scenario, the thirteenth target base station may be the same as or different from the first, second, third, or fourth target base station mentioned in the aforementioned method embodiments. Correspondingly, the fourteenth target base station may be the same as or different from the aforementioned first, second, third, or fourth target base station.

[0226] (64) If the MCG path meets the MCG path failure condition, the SCG path meets the SCG path failure condition, and the non-directly connected path meets the non-directly connected path failure condition, the remote UE performs the reconstruction operation to reconstruct the MCG path, the SCG path, and at least one of the non-directly connected paths.

[0227] The implementation process of the reconstruction operation can be referred to the relevant descriptions in the aforementioned method embodiments 200-400. To avoid repetition, it will not be repeated here.

[0228] (65) If the non-directly connected path meets the failure condition of the non-directly connected path, the MCG path does not meet the failure condition of the MCG path, and the SCG path meets the failure condition of the SCG path, the remote UE performs the operation of restoring the non-directly connected path through the MCG path, and / or the remote UE performs the operation of restoring the SCG path through the MCG path.

[0229] In this embodiment, when the remote UE performs the operation of restoring the non-directly connected path through the MCG path, the remote UE can determine the method of restoring the non-directly connected path based on whether the eleventh target base station corresponding to the MCG path supports the RRC procedure for restoring the non-directly connected path through the MCG path, as described in (651) and (652) below. It can be understood that in this embodiment, the remote UE can determine whether the eleventh target base station supports the RRC procedure for restoring the non-directly connected path through the MCG path based on whether a fourth timer is configured. If the fourth timer is configured, it is determined that the eleventh target base station supports the RRC procedure for restoring the non-directly connected path through the MCG path; otherwise, it does not. The fourth timer is used to indicate the effective duration of the RRC procedure for the remote UE to restore the non-directly connected path through the MCG path.

[0230] (651) If the eleventh target base station corresponding to the MCG path supports the RRC procedure of restoring the non-directly connected path through the MCG path, the remote UE performs the operation of restoring the non-directly connected path through the MCG path.

[0231] The process by which the remote UE restores the non-directly connected path through the MCG path may include the following (6511)-(6513), the contents of which are as follows.

[0232] (6511) The remote UE reports the non-directly connected path failure message corresponding to the non-directly connected path to the eleventh target base station corresponding to the MCG path, and starts the fourth timer.

[0233] (6512) When the remote UE receives the sixth RRC reconfiguration message sent by the eleventh target base station, it stops the fourth timer. The sixth RRC reconfiguration message includes at least the configuration information of a sixth relay UE. The configuration information of the sixth relay UE is used to instruct the remote UE to establish a non-direct path with the twelfth target base station to which the sixth relay UE belongs.

[0234] Optionally, the configuration information of the sixth relay UE can be determined by the eleventh target base station based on the relay UE information it caches, or it can be determined based on the relay information reported by the remote UE. No restriction is imposed here.

[0235] It should be noted that the eleventh target base station corresponding to the non-directly connected path and the twelfth target base station to which the sixth relay UE belongs may be the same or different. Of course, if the eleventh target base station is different from the twelfth target base station, the configuration information of the sixth relay UE included in the sixth RRC reconfiguration message may be generated by the twelfth target base station and then sent to the eleventh target base station.

[0236] (6513) If the fourth timer times out, the remote UE performs the reconstruction operation to reconstruct the non-directly connected path.

[0237] (652) If the eleventh target base station corresponding to the MCG path does not support the RRC procedure of restoring the non-directly connected path through the MCG path, the remote UE performs the reconstruction operation to reconstruct the non-directly connected path.

[0238] It should be noted that the implementation process of the reconstruction operation described in (6513) and (652) can be referred to the relevant description in the aforementioned method embodiments 200-400. To avoid repetition, it will not be repeated here.

[0239] Furthermore, the process by which the remote UE performs the operation of restoring the SCG path through the MCG path can be referred to the relevant descriptions in method embodiments 200-400, and will not be repeated here to avoid repetition.

[0240] (66) If the non-directly connected path meets the non-directly connected path failure condition, the MCG path does not meet the MCG path failure condition, and the SCG path does not meet the SCG path failure condition, the remote UE performs the operation of restoring the non-directly connected path through the MCG path, or performs the operation of restoring the non-directly connected path through the SCG path.

[0241] It is understood that the implementation process of the remote UE performing the operation of restoring the non-direct path through the MCG path can refer to the relevant descriptions in (651)-(652) above. To avoid repetition, it will not be repeated here.

[0242] Furthermore, the implementation process of the remote UE performing the operation of restoring the non-directly connected path through the SCG path can be referred to the relevant descriptions in (631)-(632) above. To avoid repetition, it will not be repeated here.

[0243] Furthermore, in scenarios where the non-directly connected path meets the non-directly connected path failure condition, the MCG path does not meet the MCG path failure condition, and the SCG path does not meet the SCG path failure condition, the remote UE can determine the method for restoring the non-directly connected path through random selection, network configuration, or protocol-defined methods.

[0244] For example, assuming the network is configured with fourth information, the remote UE can determine, based on the fourth information, whether to restore the non-directly connected path via the MCG path or via the SCG path.

[0245] The fourth information may include at least one of the following (661)-(663).

[0246] (661) Third indication information, the third indication information being used to indicate to the remote UE whether to restore the non-direct path through the MCG path or through the SCG path.

[0247] For example, the third indication information may be a 1-bit indication information configured by the network.

[0248] (662) The third threshold is the Uu link quality threshold of the SCG path.

[0249] (663) Fourth threshold, the fourth threshold being the Uu link quality threshold of the MCG path.

[0250] Based on this, the step of the remote UE determining whether to restore the non-directly connected path through the MCG path or through the SCG path according to the Uu link quality of the SCG path and / or the Uu link quality of the MCG path may include any one of the following (6631)-(6636).

[0251] (6631) If the quality of the Uu link of the SCG path meets the third threshold, the remote UE performs the operation of restoring the non-directly connected path through the SCG path.

[0252] (6632) If the quality of the Uu link of the SCG path does not meet the third threshold condition, the remote UE performs the operation of restoring the non-directly connected path through the MCG path.

[0253] (6633) If the Uu link quality of the MCG path meets the fourth threshold, the remote UE performs the operation of restoring the non-directly connected path through the MCG path.

[0254] (6634) If the quality of the Uu link of the MCG path does not meet the fourth threshold, the remote UE performs the operation of restoring the non-directly connected path through the SCG path.

[0255] (6635) If the Uu link quality of the SCG path meets the third threshold and the Uu link quality of the MCG path does not meet the fourth threshold, the remote UE performs the operation of restoring the non-directly connected path through the SCG path.

[0256] (6636) If the Uu link quality of the SCG path does not meet the third threshold, and the Uu link quality of the MCG path meets the fourth threshold, the remote UE performs the operation of restoring the non-directly connected path through the MCG path.

[0257] (67) If the non-directly connected path meets the failure condition of the non-directly connected path, the MCG path meets the failure condition of the MCG path, and the SCG path does not meet the failure condition of the SCG path, the remote UE performs the operation of restoring the MCG path through the SCG path, and / or the remote UE performs the operation of restoring the non-directly connected path through the SCG path.

[0258] The implementation process of the remote UE performing the operation of restoring the MCG path through the SCG path can be referred to the relevant description in (62), and the implementation process of the remote UE performing the operation of restoring the non-directly connected path through the SCG path can be referred to the relevant description in (631)-(632). To avoid repetition, it will not be described again here.
