[0151] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0152] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0153] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0154] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other processing methods, and next-generation systems based on and extending these systems. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0155] In some embodiments, embodiments of the present disclosure involve a packet discard mechanism, and the packet discard involved is described below. In some embodiments, the network device defines a packet discard mechanism at the PDCP layer. For example, the network device configures a timer for the PDCP entity, and when the transmitting PDCP entity receives a PDCP SDU from a higher layer, it starts a corresponding timer for the PDCP SDU. If the timer of a PDCP SDU times out, the transmitting PDCP entity will discard the PDCP SDU and the corresponding PDCP Data PDU. If the corresponding PDCP Data PDU has been sent to the RLC layer for processing, the PDCP will indicate the discard operation to the RLC layer. Optionally, the timer is a discardTimer (discard timer).

[0156] In some embodiments, each PDU Set has some parameters related to QoS processing, one of which is the PDU Set Importance (PSI). This parameter indicates the relative importance of a PDU Set relative to other PDU Sets in the same QoS Flow. When congestion occurs, PSI can be used for packet discarding. That is, when the network notifies the terminal to activate PSI-based packet discarding through MAC CE, the terminal will use a shorter timer (i.e., discardTimerForLowImportance) for PDU Sets with lower importance. In this way, the timer of the corresponding data packet will be more likely to time out and be discarded.

[0157] In some embodiments, the communication system involved in the present disclosure is applied in dual connectivity. Optionally, the dual connectivity includes MR-DC

[0158] (Multi-Radio Dual Connectivity). Optionally, the terminal can connect to different access network devices to utilize the resources provided by the access network devices. Optionally, the access network device can also be referred to as a node. In some embodiments, one access network device provides NR access, and another access network device provides E-UTRA (Evolved Universal Terrestrial Radio Access) or NR access. Optionally, one access network device serves as a primary access network device, such as a master node (MN), and the other serves as a secondary access network device, such as a secondary node (SN). In some embodiments, the MN and the SN are connected through a network interface, and at least the MN is connected to a core network device.

[0159] In some embodiments, the terminal has different types of bearers. Optionally, the bearers include MCG bearers, SCG bearers, and split bearers. In some embodiments, the split bearer refers to a bearer that supports both MCG bearers and SCG bearers. Alternatively, it can be understood that the split bearer has more comprehensive functions, not only having the functions of an MCG bearer, but also the functions of an SCG bearer.

[0160] FIG2 is an interactive diagram of a processing method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a processing method, which includes:

[0161] Step S2101: The first access network device sends configuration information to the terminal.

[0162] In some embodiments, the configuration information is used to configure a first configuration for the DRB of the terminal. In an embodiment of the present disclosure, the first access network device can configure different configurations for the DRB of the terminal so that the terminal can determine whether the corresponding DRB is configured with the first configuration.

[0163] In some embodiments, the terminal includes multiple DRBs, and different DRBs may correspond to different access network devices, and different DRBs may be configured or not configured with the first configuration.

[0164] In some embodiments, the first configuration is used to instruct the DRB to use PSI-based packet discarding. In embodiments of the present disclosure, if the DRB is configured with the first configuration, then when the first configuration is activated, the terminal may discard packets based on the PSI. If the first configuration is in an inactive state, the terminal will not discard packets based on the PSI. If the terminal is not configured with the first configuration, it will not discard packets based on the PSI either.

[0165] Step S2102: The terminal determines that a DRB configured with the first configuration is configured based on the configuration information.

[0166] In an embodiment of the present disclosure, after receiving the configuration information, the terminal can determine which DRBs are configured with the first configuration, and subsequently determine which DRBs' first configurations are in an activated state and which DRBs' first configurations are in an inactivated state.

[0167] Step S2103: The first access network device sends first information to the terminal.

[0168] In some embodiments, the terminal receives the first information sent by the first access network device. In some embodiments, the first access network device sends the first information. In some embodiments, the terminal receives the first information.

[0169] In some embodiments, the first access network device includes at least one of an MN access network device or an SN access network device. For example, if the first access network device is an MN access network device, the MN access network device sends the first information to the terminal. For example, if the first access network device is an SN access network device, the SN access network device sends the first information to the terminal. For example, if the first access network device includes an MN access network device and an SN access network device, the MN access network device and the SN access network device both send the first information to the terminal. In some embodiments, the MN access network device and the SN access network device may be the MN access network device sending the first information to the terminal, and the SN access network device sending the second information to the terminal. For another example, the MN access network device and the SN access network device may be the SN access network device sending the first information to the terminal, and the MN access network device sending the second information to the terminal.

[0170] In some embodiments, the first information is used to indicate activation / deactivation of the first configuration of at least one DRB corresponding to the first information. Optionally, the first information is used to indicate activation of the first configuration of at least one DRB corresponding to the first information. Optionally, the first information is used to indicate deactivation of the first configuration of at least one DRB corresponding to the first information. In some embodiments, activation means that the first configuration of at least one DRB corresponding to the first information is in use. Deactivation means that the first configuration of at least one DRB corresponding to the first information is not in use.

[0171] Optionally, the first information includes a certain number of bits, and different bits are used to indicate whether the first configuration of different DRBs is activated. Optionally, the DRB includes a DRB configured with the first configuration and a DRB not configured with the first configuration.

[0172] For example, the terminal is configured with 6 DRBs, namely DRB 1, DRB 2, DRB 3, DRB 4, DRB 5, and DRB 6, among which DRB1 is an MCG bearer type, the configured RLC entity corresponds to MN, and the first configuration is not configured; DRB2 is an MCG bearer type, the configured RLC entity corresponds to MN, and the first configuration is configured; DRB3 is an SCG bearer type, the configured RLC entity corresponds to SN, and the first configuration is not configured; DRB4 is an SCG bearer type, the configured RLC entity corresponds to SN, and the first configuration is configured; DRB5 is a split bearer type, the configured RLC entities correspond to MN and SN, and the first configuration is not configured; DRB6 is a split bearer type, the configured RLC entities correspond to MN and SN, and the first configuration is configured.

[0173] In some embodiments, the first information is used to indicate activation / deactivation of a first configuration of a first DRB, and the RLC entity configured with the first DRB is associated with a MAC entity of a first access network device. In some embodiments, the first information is used to indicate activation / deactivation of a first configuration of a first DRB, in which the configured RLC entity is associated with a MAC entity of a first access network device. Optionally, the association of the configured RLC entity with the MAC entity of the first access network device means that the RLC entity of the first DRB is in the MAC entity of the first access network device.

[0174] In some embodiments, the first access network device includes at least one of a MN access network device or a SN access network device. In some embodiments, the first information is used to indicate activation / deactivation of a first configuration of a first DRB, and the RLC entity configured with the first DRB is associated with a MAC entity of the MN access network device or a MAC entity of the SN access network device.

[0175] In some embodiments, the first information includes a first number of bits, and a second number of bits in the first number of bits are used to indicate activation / deactivation of a first configuration of at least one first DRB corresponding to the first information; wherein the second number of bits corresponds one-to-one to the DRB identifier of the first DRB. In an embodiment of the present disclosure, some of the bits in the first number of bits are used to indicate whether the first configuration of the corresponding first DRB is activated or deactivated. Optionally, the one-to-one correspondence between the second number of bits and the DRB identifier of the first DRB means that one bit corresponds to one first DRB. wherein the RLC entity configured with the first DRB is associated with the MAC entity of the first access network device. It can also be understood that the second number of bits refers to the DRB associated with the corresponding configured RLC entity and the MAC entity of the first access network device. Optionally, the second number is the same as the number of the first DRB.

[0176] Optionally, the second number of bits corresponds one-to-one to the first DRB. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an MN access network device, the first DRB is DRB2 and DRB6 in the above DRB, so the second number of bits correspond to DRB2 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB2, and D1 corresponds to DRB6. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an SN access network device, the first DRB is DRB4 and DRB6 in the above DRB, so the second number of bits correspond to DRB4 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB4, and D1 corresponds to DRB6.

[0177] In some embodiments, the second number of bits corresponds one-to-one in the order of the DRB identifier of the first DRB from small to large. In the embodiment of the present disclosure, the one-to-one correspondence in the order of small to large means that the second number of bits corresponds one-to-one in the order of the DRB identifier from small to large from front to back. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an MN access network device, then the first DRB is DRB2 and DRB6 in the above DRB, so the second number of bits correspond to DRB2 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB2 and D1 corresponds to DRB6. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an SN access network device, then the first DRB is DRB4 and DRB6 in the above DRB, so the second number of bits correspond to DRB4 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB4 and D1 corresponds to DRB6.

[0178] In some embodiments, the second number of bits corresponds one-to-one in descending order of the DRB identifier of the first DRB. In the embodiment of the present disclosure, the one-to-one correspondence in descending order means that the second number of bits corresponds one-to-one in descending order of the DRB identifier from front to back. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an MN access network device, the first DRB is DRB2 and DRB6 in the above DRB, so the second number of bits correspond to DRB2 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB6, and D1 corresponds to DRB2. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an SN access network device, the first DRB is DRB4 and DRB6 in the above DRB, so the second number of bits correspond to DRB4 and DRB6 respectively. For example, the second number of bits includes D0 and D1 bits, where D0 corresponds to DRB6, and D1 corresponds to DRB4.

[0179] In some embodiments, the bits in the first number of bits other than the second number of bits are ignored. In an embodiment of the present disclosure, if the first number of bits is 8 bits and the second number of bits is 2 bits, the last 6 bits are ignored.

[0180] In some embodiments, the first information is used to indicate activation / deactivation of the first configuration of the second DRB, and the terminal ignores the DRB in which the configured RLC entity in the second DRB is not associated with the MAC entity of the first access network device. In some embodiments, the first information is used to indicate activation / deactivation of the second DRB including the first configuration. Optionally, the configured RLC entity is not associated with the MAC entity of the first access network device means that the RLC entity of the first DRB is not in the MAC entity of the first access network device.

[0181] In some embodiments, the first access network device includes at least one of a MN access network device or a SN access network device. In some embodiments, the first information is used to indicate activation / deactivation of a first configuration of a second DRB, and the terminal ignores a DRB in which the configured RLC entity in the second DRB is not associated with a MAC entity of the MN access network device or a MAC entity of the SN access network device.

[0182] In some embodiments, the terminal ignores the DRB that is not associated with the MAC entity of the first access network device and the RLC entity configured in the second DRB, which means that the first information not only indicates the DRB associated with the MAC entity of the MN access network device, but also indicates the DRB associated with the MAC entity of the SN access network device. If the first access network device is the MN access network device, the terminal ignores the DRB associated with the MAC entity of the SN access network device indicated by the first information.

[0183] In some embodiments, the first information includes a first number of bits, and a third number of bits in the first number of bits are used to indicate activation / deactivation of a first configuration of at least one second DRB corresponding to the first information; wherein the third number of bits corresponds one-to-one with the DRB identifier of the second DRB. In an embodiment of the present disclosure, some of the bits in the first number of bits are used to indicate whether the first configuration of the corresponding first DRB is activated or deactivated. Optionally, the one-to-one correspondence between the third number of bits and the DRB identifier of the second DRB means that one bit corresponds to one second DRB. Optionally, the third number is the same as the number of second DRBs.

[0184] Optionally, the third number of bits corresponds one-to-one to the second DRB. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an MN access network device, the second DRB is DRB2, DRB4 and DRB6 in the above DRB, so the third number of bits corresponds to DRB2, DRB4 and DRB6 respectively. For example, the third number of bits includes D0, D1 and D2 bits, where D0 corresponds to DRB2, D1 corresponds to DRB4, and D2 corresponds to DRB6. For example, if the DRB includes DRB1-DRB6 in the above example, and the first access network device is an SN access network device, the second DRB is DRB2, DRB4 and DRB6 in the above DRB, so the third number of bits corresponds to DRB2, DRB4 and DRB6 respectively. For example, the third number of bits includes D0, D1 and D2 bits, where D0 corresponds to DRB2, D1 corresponds to DRB4, and D2 corresponds to DRB6.

[0185] In some embodiments, the third number of bits correspond one-to-one in the order of the DRB identifier of the second DRB from small to large, or the third number of bits correspond one-to-one in the order of the DRB identifier of the second DRB from large to small. In the embodiment of the present disclosure, the one-to-one correspondence in the order of small to large means that the third number of bits correspond one-to-one from front to back in the order of DRB identifiers from small to large. For example, if the DRB includes DRB1-DRB6 in the above example, and the DRB configured with the first configuration includes DRB2, DRB4 and DRB6, the third number of bits includes D0, D1 and D2 bits, where D0 corresponds to DRB2, D1 corresponds to DRB4, and D2 corresponds to DRB6. In the embodiment of the present disclosure, the one-to-one correspondence in the order of large to small means that the third number of bits correspond one-to-one from front to back in the order of DRB identifiers from large to small. For example, if the DRB includes DRB1-DRB6 in the above example, and the DRB configured with the first configuration includes DRB2, DRB4 and DRB6, the third number of bits includes D0, D1 and D2 bits, where D0 corresponds to DRB6, D1 corresponds to DRB4, and D2 corresponds to DRB2.

[0186] In some embodiments, the bits other than the third number of bits in the first number of bits are ignored. In an embodiment of the present disclosure, if the first number of bits is 8 bits and the third number of bits is 3 bits, the last 5 bits are ignored.

[0187] Step S2104: The terminal activates / deactivates the first configuration of the DRB based on the indication of the first information.

[0188] In some embodiments, determining the first configuration of the DRB indicated for activation / deactivation by the first access network device based on the first information includes: when the first configuration of the third DRB indicated for activation / deactivation by the first information conflicts with the first configuration of the third DRB indicated for activation / deactivation by the second information, activating / deactivating the first configuration of the third DRB based on the first rule; wherein the second information is sent by the second access network device. Optionally, the second access network device can also be understood as an access network device different from the first access network device in the above embodiment. For example, if the first access network device is an MN access network device, then the second access network device is an SN access network device. Alternatively, if the first access network device is an SN access network device, then the second access network device is an MN access network device. In some embodiments, the second access network device can also be understood as the first access network device, the difference being that the first access network device in steps S2101-S2103 above is one type of access network device, and the second access network device in step S2104 is another type of first access network device.

[0189] It should be noted that the first rule in the embodiments of the present disclosure is effective for a certain duration. In some embodiments, within a first duration after receiving the first information, the terminal executes the first configuration of activating / deactivating at least one DRB corresponding to the first information based on the first rule. Optionally, the first duration is agreed upon by the communication protocol, configured by the network device, or set in other ways.

[0190] In some embodiments, the first rule includes at least one of the following:

[0191] (1) Activate / deactivate the first configuration of the third DRB according to the instruction of the first information.

[0192] In some embodiments, the priority of the first information is higher than the priority of the second information. Therefore, the first configuration of the third DRB is activated / deactivated according to the instructions of the first information.

[0193] (2) Activate / deactivate the first configuration of the third DRB according to the instruction of the second information.

[0194] In some embodiments, the priority of the second information is higher than the priority of the first information. Therefore, the first configuration of the third DRB is activated / deactivated according to the indication of the second information.

[0195] (3) Activate the first configuration of the third DRB.

[0196] In some embodiments, the first configuration of the third DRB is directly activated by default. In some embodiments, the step of activating the first configuration of the third DRB is performed by communication protocol agreement or network device configuration.

[0197] (4) Deactivate the first configuration of the third DRB.

[0198] In some embodiments, the first configuration of the third DRB is directly deactivated by default. In some embodiments, the step of deactivating the first configuration of the third DRB is performed by communication protocol agreement or network device configuration.

[0199] In some embodiments, activating / deactivating the first configuration of the third DRB according to the instruction of the first information includes any one of the following:

[0200] (1) For a third DRB of any bearer type, activate / deactivate the first configuration of the third DRB according to the instruction of the first information;

[0201] (2) for a third DRB of the MCG bearer type, activating / deactivating the first configuration of the third DRB according to the instruction of the first information;

[0202] (3) For the third DRB of the split bearer type, activate / deactivate the first configuration of the third DRB according to the instruction of the first information.

[0203] In some embodiments, activating / deactivating the first configuration of the third DRB according to the instruction of the second information includes any one of the following:

[0204] (1) For a third DRB of any bearer type, activate / deactivate the first configuration of the third DRB according to the instruction of the first information;

[0205] (2) for a third DRB of the SCG bearer type, activating / deactivating the first configuration of the third DRB according to the instruction of the first information;

[0206] (3) For the third DRB of the split bearer type, activate / deactivate the first configuration of the third DRB according to the instruction of the first information.

[0207] In some embodiments, activating the first configuration of the third DRB includes any of the following:

[0208] (1) For the third DRB of any bearer type, activate the first configuration of the third DRB;

[0209] (2) For the third DRB of the split bearer type, activate the first configuration of the third DRB.

[0210] In some embodiments, deactivating the first configuration of the third DRB includes any of the following:

[0211] (1) For the third DRB of any bearer type, deactivate the first configuration of the third DRB;

[0212] (2) For the split third DRB, deactivate the first configuration of the third DRB.

[0213] Step S2105: The first access network device sends third information to the second access network device.

[0214] In some embodiments, the third information is used to instruct the first access network device to instruct the terminal to activate / deactivate the first configuration of the DRB.

[0215] Step S2106: The second access network device determines the first configuration of activating / deactivating the DRB based on the third information.

[0216] In an embodiment of the present disclosure, the first access network device and the second access network device can negotiate to explain their own activation / deactivation status of the DRB of the terminal so that the other access network device no longer performs the opposite operation on the DRB.

[0217] Optionally, the MN access network device notifies the SN access network device that DRB 2 has activated the first configuration and DRB 6 has deactivated the first configuration. When the SN access network device sends first information to activate / deactivate the first configuration, the SN access network device may set DRB 2 to active to avoid conflict with the MN access network device. With respect to DRB 6, the SN access network device decides whether to activate or deactivate the first configuration based on its own congestion status and the notification from the MN access network device.

[0218] It should be noted that steps S2105 and S2106 in the embodiment of the present disclosure are optional steps. In another embodiment, steps S2105 and S2106 may not be performed.

[0284] FIG6 is a flow chart of a processing method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a processing method, which includes:

[0285] Step S6101: activating / deactivating the MAC CE for PSI-based packet discard only controls the DRBs for which PSI-based packet discard is configured and for which an RLC entity is associated with the current MAC CE entity.

[0286] In some embodiments, for example, it is assumed that the UE has the following configuration:

[0287] DRB ID 1: MCG bearer, the configured RLC entities are all in the MN MAC entity, and PSI-based packet discard is not configured for this DRB.

[0288] DRB ID 2: MCG bearer, the configured RLC entities are all in the MN MAC entity, and this DRB is configured with PSI-based packet discard.

[0289] DRB ID 3: SCG bearer, the configured RLC entities are all in the SN MAC entity, and this DRB is not configured with PSI-based packet discard.

[0290] DRB ID 4: SCG bearer, the configured RLC entities are all in the SN MAC entity, and this DRB is configured with PSI-based packet discard.

[0291] DRB ID 5: Split bearer, the configured RLC entity is in the MN MAC entity and the SN MAC entity, and this DRB is not configured with PSI-based packet discard.

[0292] DRB ID 6: Split bearer, the configured RLC entity is in the MN MAC entity and the SN MAC entity, and this DRB is configured with PSI-based packet discard.

[0293] In some embodiments, when the MN sends a MAC CE to activate / deactivate PSI-based packet discard, D0 in the bitmap corresponds to DRB ID 2, D1 corresponds to DRB ID 6, and D2 to D7 will be ignored.

[0294] In some embodiments, when the SN sends a MAC CE to activate / deactivate PSI-based packet discard, D0 in the bitmap corresponds to DRB ID 4, D1 corresponds to DRB ID 6, and D2 to D7 will be ignored.

[0295] In some embodiments, the bitmap of the MAC CE for activating / deactivating PSI-based packet discard indicates all DRBs configured with PSI-based packet discard (i.e., configured with discardTimerForLowImportance), but the UE ignores DRBs that have no RLC entity associated with this MAC entity.

[0296] In some embodiments, when the MN or SN sends a MAC CE to activate / deactivate PSI-based packet discard, D0 in the bitmap corresponds to DRB ID 2, D1 corresponds to DRB ID 4, and D2 corresponds to DRB ID 6. D3 to D7 are ignored. When the UE receives a MAC CE to activate / deactivate PSI-based packet discard from the MN, the UE ignores D1; ​​when the UE receives a MAC CE to activate / deactivate PSI-based packet discard from the SN, the UE ignores D0.

[0297] In some embodiments, the bitmap of the MAC CE for activating / deactivating PSI-based packet discard indicates all DRBs configured with PSI-based packet discard (i.e., configured with discardTimerForLowImportance), and the UE handles the conflicting MAC CEs for activating / deactivating PSI-based packet discard according to certain rules. For example, when the UE receives a MAC CE for activating / deactivating PSI-based packet discard sent by a network node (e.g., MN), where the activation / deactivation of PSI-based packet discard for a certain (or multiple) DRB conflicts with the indication of the MAC CE for activating / deactivating PSI-based packet discard previously sent from another network node (e.g., MN) (i.e., one node activates PSI-based packet discard for a DRB, and another node deactivates PSI-based packet discard for this DRB), the UE handles it according to certain rules. These rules include:

[0298] a) Regardless of the bearer type, activation / deactivation is performed according to the MAC CE sent by the MN;

[0299] b) Regardless of the bearer type, activation / deactivation is performed according to the MAC CE sent by the SN;

[0300] c) For the MCG bearer, activate / deactivate according to the MAC CE sent by the MN;

[0301] d) For SCG bearer, activate / deactivate according to the MAC CE sent by SN;

[0302] e) For the split bearer, activate / deactivate according to the MAC CE sent by the MN;

[0303] f) For split bearer, activate / deactivate according to the MAC CE sent by the SN;

[0304] g) Activate PSI-based packet discard regardless of bearer type;

[0305] h) PSI-based packet discarding is disabled regardless of the bearer type;

[0306] i) For split bearer, activate PSI-based packet dropping;

[0307] j) For split bearer, deactivate PSI-based packet discarding;

[0308] In some embodiments, these rules may be specified by a standard or configured by the network, for example, via RRC signaling. The granularity of the configuration may be UE, MAC entity, or DRB.

[0309] In some embodiments, the UE applies the above rules based on the time interval between MAC CEs received from two nodes. Specifically, the UE applies the above rules only when the time interval is less than a threshold; otherwise, the UE processes only the most recently received MAC CE. This threshold can be specified by the standard, such as 2ms, or it can be network-configured, for example, via RRC signaling.

[0310] In some embodiments, the MN and SN coordinate PSI-based packet discarding via Xn signaling. For example, the MN and SN use Xn signaling to notify each other of the current activation / deactivation status of DRBs configured with PSI-based packet discarding (i.e., configured with discardTimerForLowImportance), thereby avoiding conflicts between MAC CEs sent by different nodes.

[0311] In some embodiments, the MN notifies the SN via Xn signaling that PSI-based packet discarding has been activated in DRB 2 and deactivated in DRB 6. Therefore, when the SN sends a MAC CE to activate / deactivate PSI-based packet discarding, it can set DRB 2 to active (D0 to 1) to avoid conflict with the MN. For DRB 6 (D2 in the MAC CE), the SN decides whether to activate or deactivate PSI-based packet discarding based on its own congestion status and the Xn signaling sent by the MN.

[0312] In some embodiments, the MN notifies the SN via Xn signaling that PSI-based packet discarding has been deactivated in DRB 6. Thus, when the SN sends a MAC CE to activate / deactivate PSI-based packet discarding, the SN decides whether to activate or deactivate PSI-based packet discarding for DRB 6 (D1 in the MAC CE) based on its own congestion status and the Xn signaling sent by the MN.

[0313] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
