Description

Technical Field

[0002] Currently, in the SCG (Secondary Cell) activation mechanism, the UE (User Equipment) will not monitor the PDCCH (Physical Downlink Control Channel) during the SCG deactivation period, and will only start monitoring the PDCCH when the activation is completed. In the DRX mechanism, when DRX is configured, the UE will monitor the PDCCH only when the MAC entity is in the activation time (for example, the DRX is in the duration time), otherwise it will not monitor the PDCCH.

[0003] If we consider the case where DRX is not on duration when SCG is activated, the UE cannot monitor PDCCH during the activation process and needs to wait until the next on duration to start monitoring PDCCH. As a result, the UE cannot monitor PDCCH immediately, resulting in a large transmission delay of PDCCH. Summary of the invention

[0038] The following is an explanation of the terms and background technologies involved in this application.

[0039] 1. Discontinuous Reception (DRX)

[0040] The purpose of DRX is to save power. The terminal in DRX state does not need to connect to monitor the control channel. The DRX cycle consists of the on duration (i.e., On Duration) and the opportunity time for DRX (i.e., Opportunity for DRX): During the On Duration time, that is, the UE's DRX is in the active time (Active time), the UE monitors the PDCCH (Physical Downlink Control Channel); during the "Opportunity for DRX" time, the UE does not monitor the PDCCH to save power consumption.

[0041] It should be noted that the above-mentioned On Duration may also be called working duration, and the time of the above-mentioned opportunity for DRX may also be called intermittent duration.

[0042] In addition, the network configures an inactivity timer (ie, inactivity timer). If a new PDCCH is received within the on duration, the inactivity timer will be started or restarted to extend the time for the UE to monitor the PDCCH.

[0043] In combination with the above DRX basic model, Table 1 gives a description of the DRX timer.

[0044]

[0045]

[0046]

[0047] Table 1

[0048] It should be noted that the MAC entity monitors the PDCCH only during the active period. When the DRX cycle is configured, the active period includes:

[0049] drx-onDurationTime or drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, ra-ContentionResolutionTimer or msgB-ResponseWindow (i.e., the MAC entity is waiting for a message on random access conflict resolution) is running;

[0050] An SR has been sent on the PUCCH and is currently in the pending state (i.e., waiting for an UL grant);

[0051] After the MAC entity successfully receives the RAR in response to "a preamble not selected from the contention-based preamble set", it has not yet received the PDCCH indicating the initial transmission and scrambling with the C-RNTI.

[0052] 2. Basic Concepts of DC / CA

[0053] Dual Connectivity (DC) means providing the UE with resources of two network nodes (access network elements), one of which is called MN (Master node) and the other is called SN (Secondary node). Carrier aggregation technology (CA) is used at each network node, that is, a series of service cells controlled by the node, also called cell groups, are configured for the UE. The master node MN controls the master cell group (MCG), and the secondary node SN controls the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (Scell). In MCG, the special cell is called the primary cell (PCell), and in SCG, the special cell is called the primary secondary cell (PSCell). In a cell group, SpCell uses the main carrier, while other secondary cells use secondary carriers. Resource scheduling within a cell group is performed by SpCell.

[0054] 3. SCG activation / deactivation mechanism

[0055] Rel-16 introduced the SCG suspended state. When the UE has low data transmission or no data transmission on the SCG for a long time, the network can temporarily suspend the SCG instead of directly deleting the SCG and then adding it back when larger data appears. Temporarily suspending the SCG allows the terminal to work in a more power-saving manner for a longer period of time, and the SCG can be restored more quickly when there is a large amount of data demand. During the Rel-17 standardization process, the term SCG deactivation was used. SCG deactivation can also be initiated for the purpose of terminal overheating or power saving.

[0056] During SCG deactivation, the UE does not monitor the PDCCH on the SCG and does not perform PUSCH and SRS transmissions. For other UE behaviors during SCG deactivation, some behaviors will be restricted to save UE power consumption, and other behaviors (including RLM and BFD) can continue to be executed to speed up SCG activation to start data transmission as soon as possible. There are two mechanisms for SCG to activate from deactivation: one is a RACH-based activation process, in which the activation command carries RACH resource configuration and initiates the RACH process. The other is a RACH-less based activation process, which omits the RACH process.

[0057] The protocol defines RACH-less based and RACH-based SCG activation delays.

[0058] Among them, from the above definition of TΔ and TIU, it can be obtained that: after the UE completes accurate time tracking (to obtain the complete timing information of the target PSCell), for RACH-based SCG activation, the first available PRACH opportunity in the PSCell will be obtained. For RACH-less based SCG activation, the first available PUSCH opportunity (or SR on PUCCH) will be obtained, and the SCG activation process ends here.

[0059] The timer operation method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0060] Figure 2 A flowchart of a timer operation method provided in an embodiment of the present application, such as Figure 2 As shown, the timer operation method may include the following steps S201:

[0061] Step S201: The UE performs a first operation at a first moment, where the first operation includes any one of the following:

[0062] The UE starts a timer and monitors the physical downlink control channel PDCCH during the timer.

[0063] The UE does not follow the DRX configuration and monitors the PDCCH.

[0064] The first moment is related to the activation process of the UE performing SCG activation of the secondary cell group, and the activation process includes: SCG direct activation process or SCG activation process based on random access; the PDCCH is used to transmit data related to the SCG.

[0065] In the embodiment of the present application, the above-mentioned UE is configured with DRX configuration.

[0066] Optionally, in an embodiment of the present application, the above-mentioned SCG direct activation process is that the UE does not perform a random access process when performing the SCG activation process.

[0067] It should be noted that the SCG direct activation process is the RACH-less based SCG activation process; the SCG activation process based on random access is the RACH-based SCG activation process.

[0068] In some possible implementations, the UE starts a timer at a first moment, and is in an awake state and monitors the PDCCH while the timer is running.

[0069] Optionally, in the embodiment of the present application, the timer includes any one of the following:

[0070] DRX inactivity timer defined in the protocol;

[0071] Newly introduced timer.

[0072] Exemplarily, the timer defined in the above protocol may be a DRX inactivity timer (ie, drx-InactivityTimer) defined in TS38.321.

[0073] It should be noted that the above-mentioned inactivity timer may also be referred to as an inactivity timer.

[0074] Exemplarily, the newly introduced timer may be a DRX activation timer (ie, drx-activationTimer).

[0075] Optionally, in an embodiment of the present application, the timer length of the above-mentioned timer may be agreed upon by a protocol or configured by a network side device.

[0076] Optionally, in an embodiment of the present application, during the operation of the above-mentioned timer, a MAC (Media Access Control) entity of the UE is within an activation time or in a state of monitoring a PDCCH.

[0077] It should be noted that when the MAC entity of the UE is in the activation time, the UE can monitor the PDCCH.

[0078] In some other possible implementations, the UE does not follow the original DRX configuration at the first moment, and monitors the PDCCH during the period when the original DRX configuration is not followed.

[0079] Optionally, in an embodiment of the present application, the network side device may instruct the UE to use the no DRX configuration at the first moment, and after applying the no DRX configuration, the UE does not follow the original DRX configuration.

[0080] It should be noted that the UE uses the no DRX configuration, which means that the UE does not use the original DRX configuration.

[0081] Optionally, in an embodiment of the present application, the UE may not follow the original DRX configuration at the first moment, and monitor the PDCCH during the period of not following the original DRX configuration.

[0082] Optionally, in the embodiment of the present application, the first moment may include any of the following:

[0083] During the SCG activation process, the UE obtains the time corresponding to the complete timing information of the SCG;

[0084] The moment when the UE obtains the first available PUSCH;

[0085] The time when the UE obtains the first available SR (Scheduling Request);

[0086] The time corresponding to the activation of SCG as agreed in the agreement;

[0087] The upper layer indicates the time corresponding to when the SCG is activated;

[0088] The moment when the UE receives the SCG activation command;

[0089] The moment when the fourth timer stops, the fourth timer may be a contention resolution timer (ie, ra-ContentionResolutionTimer).

[0090] Exemplarily, the moment corresponding to when the UE acquires the complete timing information of the SCG may be the moment corresponding to when the UE completes precise timing tracking.

[0091] Exemplarily, the time corresponding to the activation of the SCG agreed upon in the protocol may be the time corresponding to the activation of the SCG defined in TS38.133.

[0092] Exemplarily, the moment when the upper layer indicates that the SCG is activated may include: the moment when the upper layer sends the indication information for activating the SCG, or the moment when the SCG is activated after the upper layer sends the indication information for activating the SCG.

[0093] In the timer operation method provided in the embodiment of the present application, the UE performs a first operation at a first moment, and the UE is configured with a DRX configuration, and the above-mentioned first operation includes any one of the following: the UE starts a timer, and during the operation of the timer, monitors the downlink physical control channel PDCCH; the UE does not follow the DRX configuration and monitors the PDCCH; wherein the above-mentioned first moment is related to the activation process of the UE performing the secondary cell group SCG activation, and the above-mentioned activation process includes: SCG direct activation process or SCG activation process based on random access, and the above-mentioned PDCCH is used to transmit data related to the SCG. Through this method, during the activation process of the SCG, the time for the UE to start monitoring the PDCCH is set by the timer, or the UE may not follow the original DRX configuration, so that the UE can start monitoring the PDCCH at the first moment, so that the UE can quickly monitor the PDCCH during the SCG activation process, thereby reducing the transmission delay of the PDCCH.

[0094] Optionally, in the embodiment of the present application, after the UE starts the timer in the above step S201, the timer operation method provided in the embodiment of the present application further includes the following step S202 or step S203:

[0095] Step S202: When the timer times out, the MAC entity of the UE enters sleep time.

[0096] Step S203: When the timer times out, the UE stops monitoring the PDCCH.

[0097] Exemplarily, if there are no other factors causing the MAC entity of the UE (ie, the MAC entity) to be in the activation time, the MAC entity of the UE enters the sleep time.

[0098] Exemplarily, if there are no other factors causing the MAC entity of the UE to be in the active time, the UE stops monitoring the PDCCH or the PDCCH command (ie, the PDCCH order).

[0099] In some possible implementations, for the SCG direct activation process, the UE runs a first timer at a first moment and monitors the PDCCH during the first timer.

[0100] Optionally, in an embodiment of the present application, the UE performs an SCG direct activation process; the first moment includes any one of the following:

[0101] During the SCG activation process, the UE obtains the time corresponding to the complete timing information of the SCG;

[0102] The moment when the UE obtains the first available PUSCH;

[0103] The moment when the UE obtains the first available SR;

[0104] The time corresponding to the activation of SCG as agreed in the agreement;

[0105] The upper layer indicates the time when the SCG is activated.

[0106] Optionally, in an embodiment of the present application, the UE performs an SCG direct activation process; the timer includes a first timer;

[0107] The starting condition for starting the first timer at the first moment includes any one of the following:

[0108] The first moment is not within the duration of the DRX cycle of the UE;

[0109] The first moment is within the DRX on-duration period of the UE's MAC entity, and the time interval between the first moment and the third moment is greater than the first time interval, and the third moment is the starting moment of the on-duration period of the next DRX cycle of the UE's MAC entity.

[0110] In this way, the UE can start the timer when the DRX cycle of the MAC entity is outside the activation time, and monitor the PDCCH during the timer running, thereby breaking the restriction of the original DRX configuration on the UE monitoring of the PDCCH, so that the UE can quickly monitor the PDCCH during the SCG activation process, thereby reducing the PDCCH transmission delay.

[0111] Figure 3 The schematic diagram of the running time of the first timer and the DRX cycle of the MAC entity of the UE provided in the embodiment of the present application. Figure 3 As shown, during the operation of the DRX on-duration timer (i.e., drx-onduration Timer) of the UE, the UE monitors the PDCCH during the on-duration period, and after the first timer is started at the first moment, the UE monitors the PDCCH during the operation of the first timer, and during the operation of the DRX on-duration timer and the first timer, the MAC entity of the UE is in the activation time, and will not enter the sleep state without monitoring the PDCCH after the drx-onduration Timer times out. After entering the next DRX cycle of the MAC entity of the UE, the UE monitors the PDCCH during the on-duration period, and after the first timer is started at the first moment, the UE monitors the PDCCH during the operation of the first timer.

[0112] It should be noted that the first moment mentioned above may be a moment during the operation of the drx-onduration Timer.

[0113] It should be noted that the above-mentioned first operation can be performed for each DRX cycle of the UE, or the above-mentioned first operation can be performed for part of the DRX cycles of the UE, and the implementation of this application does not limit this.

[0114] Exemplarily, the first timer may be the drx-InactivityTimer defined in TS38.321 or the newly introduced timer drx-activationTimer.

[0115] Exemplarily, for drx-activationTimer, the UE may be in any of the following states during the timer running:

[0116] Activation time, that is, the MAC entity of the UE is in the Active time;

[0117] The UE monitors PDCCH, and there is no impact between this timer and the activation time.

[0118] Exemplarily, for drx-activationTimer, its timer length may be agreed upon by the protocol or configured by the network.

[0119] Exemplarily, after drx-activationTimer expires, if there are no other factors causing the UE's MAC entity to be in activation time, the UE's MAC entity enters sleep time; or, if there are no other factors causing the UE's MAC entity to be in activation time, the UE stops monitoring PDCCH or PDCCH order.

[0120] Optionally, in an embodiment of the present application, the UE performs an SCG direct activation process; the timer includes a first timer;

[0121] After the UE starts the first timer, the method further includes the following steps A1:

[0122] Step A1: When a first condition is met, the UE stops the first timer.

[0123] The first condition includes at least one of the following:

[0124] There is no uplink new transmission indication from any MAC entity in the PDCCH;

[0125] There is no new downlink transmission indication from any MAC entity in the PDCCH;

[0126] There is no new transmission indication of the sidelink from any MAC entity in the PDCCH;

[0127] The DRX of the MAC entity of the UE is in the on-duration of the next DRX cycle.

[0128] Exemplarily, if the PDCCH does not have any new transmission indication of the downlink (DL), uplink (UL) or sidelink (SL) of any MAC entity, the first timer is stopped. After stopping the first timer, the UE continues to follow the original DRX configuration to execute the existing UE behavior.

[0129] Exemplarily, when the DRX cycle of the MAC entity of the UE is within the duration of the next on-duration, the first timer is stopped.

[0130] In this way, when the UE does not need to monitor the PDCCH or is already in the on-duration phase and can monitor the PDCCH, the UE can follow the original DRX configuration without starting a timer or breaking the restrictions of the existing DRX configuration to monitor the PDCCH, thereby reducing the power consumption of the UE.

[0131] In some other possible implementations, for the SCG direct activation process, the UE runs a first timer upon receiving an SCG activation command and always monitors the PDCCH during the timer operation, or uses the no DRX configuration upon receiving an activation command, that is, the UE does not follow the original DRX configuration.

[0132] Optionally, in an embodiment of the present application, the UE performs an SCG direct activation process; the first moment includes any one of the following:

[0133] The moment when the UE receives the SCG activation command;

[0134] The upper layer indicates the time when the SCG is activated.

[0135] Optionally, in an embodiment of the present application, the UE performs an SCG direct activation process; the timer includes a second timer; after the UE starts the timer, the timer operation method provided in the embodiment of the present application further includes the following steps B1:

[0136] Step B1: When the second condition is met, the UE stops the second timer.

[0137] The second condition includes at least one of the following:

[0138] There is no uplink new transmission indication from any MAC entity in the PDCCH;

[0139] There is no new downlink transmission indication from any MAC entity in the PDCCH;

[0140] There is no new transmission indication of the sidelink from any MAC entity in the PDCCH;

[0141] The DRX of the MAC entity of the UE is within the on-duration of the next DRX cycle;

[0142] Beam failure or radio link failure occurs during SCG activation.

[0143] Exemplarily, the second timer may be the drx-InactivityTimer defined in TS38.321 or the newly introduced timer drx-activationTimer.

[0144] Exemplarily, for drx-activationTimer, the UE may be in any of the following states during the timer running:

[0145] Activation time, that is, the MAC entity of the UE is in the Active time;

[0146] The UE monitors the PDCCH. This timer has no impact on the activation time.

[0147] Exemplarily, for drx-activationTimer, its timer length may be agreed upon by the protocol or configured by the network.

[0148] Exemplarily, after drx-activationTimer expires, if there are no other factors causing the UE's MAC entity to be in activation time, the UE's MAC entity enters sleep time; or, if there are no other factors causing the UE's MAC entity to be in activation time, the UE stops monitoring PDCCH or PDCCH order.

[0149] In one example, within a preset time period D1, if the PDCCH does not have any new transmission indication of any MAC entity for downlink (Down Link, DL), uplink (UP Link, UL) or sidelink (Sidelink, SL), the first timer is stopped. After stopping the first timer, the UE continues to follow the original DRX configuration to execute the existing UE behavior.

[0150] Exemplarily, the starting point of the above-mentioned time period D1 may be a moment corresponding to X milliseconds after the first moment, and the value of X is related to the empirical value of the SCG activation delay.

[0151] In another example, when a beam failure (i.e., beam failure) or a radio link failure (i.e., radio link failure) occurs during the SCG activation process, the first timer is stopped. After stopping the first timer, the UE continues to follow the original DRX configuration to execute the existing UE behavior.

[0152] Optionally, in the embodiment of the present application, the UE performs the SCG direct activation process; when the UE does not follow the DRX configuration, the timer operation method provided in the embodiment of the present application further includes the following steps C1:

[0153] Step C1: The UE follows the original DRX configuration at the second moment.

[0154] The second moment mentioned above includes any one of the following:

[0155] The moment of completing SCG activation;

[0156] The moment when the UE obtains the first available PUSCH (Physical Uplink Shared Channel);

[0157] The moment when the UE obtains the first available SR on the PUCCH;

[0158] The time after there is no uplink new transmission indication from any MAC entity in the PDCCH;

[0159] The time after there is no new downlink transmission indication from any MAC entity in the PDCCH;

[0160] The time after which there is no new sidelink transmission indication from any MAC entity in the PDCCH.

[0161] Exemplarily, at the time corresponding to the completion of the SCG activation process, or the time corresponding to the first available PUSCH opportunity or the SR opportunity on the PUCCH, the UE can end the application of the no DRX configuration, that is, follow the original DRX configuration. In this way, the UE can follow the original DRX configuration when it is not necessary to monitor the PDCCH for data transmission, without starting the timer or breaking the restrictions of the existing DRX configuration to monitor the PDCCH, thereby reducing the power consumption of the UE.

[0162] In some other possible implementations, for the SCG activation process based on random access, the UE runs a third timer and monitors the PDCCH during the running of the third timer.

[0163] Optionally, in an embodiment of the present application, the UE performs an SCG activation process based on random access; the above-mentioned first moment is the moment when the fourth timer stops, and the above-mentioned fourth timer is a contention resolution time timer.

[0164] Optionally, in an embodiment of the present application, the UE performs an SCG activation process based on random access; the timer includes a third timer; and a start condition for starting the third timer at the first moment includes at least one of the following:

[0165] The fourth timer stops and the first moment is outside the DRX on duration of the MAC entity of the UE;

[0166] At the first moment, the DRX of the MAC entity of the UE is not in the on-duration period, and the time interval between the first moment and the third moment is greater than the second time interval. The above third moment is the starting moment of the on-duration period of the next DRX cycle of the MAC entity of the UE.

[0167] Exemplarily, the third timer may be the drx-InactivityTimer defined in TS38.321 or the newly introduced timer drx-activationTimer.

[0168] Exemplarily, for drx-activationTimer, the UE may be in any of the following states during the timer running:

[0169] Activation time, that is, the MAC entity of the UE is in the Active time;

[0170] The UE monitors the PDCCH. This timer has no impact on the activation time.

[0171] Exemplarily, for drx-activationTimer, its timer length may be agreed upon by the protocol or configured by the network.

[0172] In one example, when the ra-ContentionResolutionTimer stops and the DRX cycle of the UE's MAC entity is outside the activation time (ie, active time), the UE starts the drx-activationTimer.

[0173] In another example, ra-ContentionResolutionTimer stops and DRX is outside the active time, and this time and the time when the next DRX starts are in the on duration T on-duration When the time interval between the two is greater than δT, the UE starts the drx-activationTimer.

[0174] In this way, the UE can start the timer when the DRX of the MAC entity is outside the activation time, and monitor the PDCCH during the timer running, thereby breaking the restriction of the original DRX configuration on the UE monitoring of the PDCCH, so that the UE can quickly monitor the PDCCH during the SCG activation process, thereby reducing the PDCCH transmission delay.

[0175] Exemplarily, after drx-activationTimer expires, if there are no other factors causing the UE's MAC entity to be in activation time, the UE's MAC entity enters sleep time; or, if there are no other factors causing the UE's MAC entity to be in activation time, the UE stops monitoring PDCCH or PDCCH order.

[0176] Optionally, in the embodiment of the present application, the UE performs an SCG activation process based on random access; the timer includes a third timer; after the UE starts the timer, the timer operation method provided in the embodiment of the present application further includes the following steps D1:

[0177] Step D1: When the third condition is met, the UE stops the third timer;

[0178] The third condition mentioned above includes at least one of the following:

[0179] There is no uplink new transmission indication from any MAC entity in the PDCCH;

[0180] There is no new downlink transmission indication from any MAC entity in the PDCCH;

[0181] There is no new transmission indication of the sidelink from any MAC entity in the PDCCH;

[0182] The DRX of the MAC entity of the UE is in the on-duration of the next DRX cycle.

[0183] In this way, when the UE does not need to monitor the PDCCH or is already in the on-duration phase and can monitor the PDCCH, the UE can follow the original DRX configuration without starting a timer or breaking the restrictions of the existing DRX configuration to monitor the PDCCH, thereby reducing the power consumption of the UE.

[0189] DRX inactivity timer (i.e., drx-InactivityTimer);

[0190] DRX cycle;

[0191] DRX downlink retransmission timer (i.e., drx-RetransmissionTimerDL);

[0192] DRX downlink hybrid automatic repeat request round trip time timer (ie, drx-HARQ-RTT-TimerDL);

[0193] DRX uplink retransmission timer (i.e., drx-RetransmissionTimerUL);

[0194] DRX uplink hybrid automatic repeat request round trip time timer (ie, drx-HARQ-RTT-TimerUL);

[0195] DRX short cycle timer (ie, drx-ShortCycleTimer);

[0196] The length of the DRX short cycle.

[0197] Step S302: The first network side device receives first indication information from the second network side device.

[0198] Step S303: The first network side device sends a first SCG activation command to the UE based on the DRX configuration in the first indication information.

[0199] Among them, the above-mentioned first SCG activation command is used to activate the SCG of the second network side device.

[0200] Optionally, in an embodiment of the present application, the first network side device may parse the first indication information and read the DRX configuration therefrom.

[0201] Optionally, the above DRX configuration is the DRX configuration of the UE.

[0202] Optionally, in an embodiment of the present application, the first network side device may generate a first SCG activation command based on the DRX configuration.

[0203] Step S304: The UE receives a first SCG activation command from a first network side device.

[0204] Among them, the above-mentioned first SCG activation command is used to activate SCG.

[0205] In the SCG activation configuration method provided in the embodiment of the present application, a first network side device receives first indication information from a second network side device, wherein the first indication information includes a DRX configuration; the first network side device sends a first SCG activation command to the UE based on the DRX configuration in the first indication information; wherein the first SCG activation command is used to activate the SCG of the second network side device. Through this method, the first network side device can send the SCG activation command to the UE according to the DRX configuration of the UE, so that the first network side device can select an appropriate time to send the DRX activation command according to the DRX configuration, so that when the SCG is activated or the SCG activation process is completed, the UE's MAC entity is within the activation time and can monitor the PDCCH as soon as possible.

[0206] Combined with the above Figure 4 ,like Figure 5 As shown, before the above step S302, the SCG activation configuration method provided in the embodiment of the present application further includes the following steps S305 to S307:

[0207] Step S305: The first network side device sends second indication information to the second network side device.

[0208] Among them, the above-mentioned second indication information is used to notify that the SCG is about to be activated.

[0209] Among them, the above DRX configuration is an updated DRX configuration.

[0210] Optionally, in an embodiment of the present application, the updated DRX configuration is a DRX configuration updated to the original DRX configuration of the UE.

[0211] Step S306: The second network side device receives the second indication information from the first network side device.

[0212] Among them, the above-mentioned second indication information is used to indicate that the SCG of the second network side device is about to be activated.

[0213] Step S307: When the DRX configuration of the UE meets a preset update condition, the second network side device sends first indication information to the first network side device.

[0214] Among them, the above-mentioned first indication information includes the updated DRX configuration, and the DRX configuration is used to activate the SCG.

[0215] Optionally, in an embodiment of the present application, the preset update condition includes: the on-duration time of the DRX cycle in the DRX configuration is less than a third threshold.

[0216] Optionally, the third threshold may be an empirical value provided by the SN, and the empirical value is related to the SCG activation delay.

[0217] Exemplarily, the SN determines whether the current DRX configuration needs to be updated; wherein, the criteria for determining whether an update is required include but are not limited to: if the DRX on-duration time in the current DRX configuration is less than a threshold, the DRX configuration needs to be updated; if it is determined that the current DRX configuration is updated, the SN sends the updated DRX configuration to the MN; if not updated, no need to send.

[0218] Exemplarily, when the SN determines that the current DRX configuration needs to be updated, the SN may send the updated DRX configuration to the UE to trigger an update of the original DRX configuration of the UE.

[0219] According to the SCG activation configuration method provided in the embodiment of the present application, the first network side device can send indication information to the second network side device indicating that the SCG is about to be activated. After receiving the indication information, the second network side device can determine whether the DRX configuration of the UE needs to be updated, and if the DRX configuration of the UE needs to be updated, send the updated DRX configuration to the first network side device, so that the first network side device can send the SCG activation command to the UE according to the DRX configuration of the UE, so that the first network side device can select the appropriate time to send the DRX activation command according to the DRX configuration, so that when the SCG is activated or the SCG activation process is completed, the UE's MAC entity is within the activation time and can monitor the PDCCH as soon as possible.
