In the method, a communication device sends a request message to a network device; the network device can send a first message to the communication device after receiving the request message, wherein the first message is used for the communication device to determine to prolong the duration of an activated state during DRX; and the communication device prolongs the activated state after receiving the first message. The communication device can make a request to the network device to prolong the duration of the activated state, and prolong the activated state after receiving the first message sent by the network device.

Taking the UE as an example, in the DRX mode, the UE is alternately placed. Active state and sleep state, and the UE turns on the receiver to listen for and receive downlink data and signaling only when it is in an active state, and turns off the receiver to stop receiving downlink data and signaling when in the sleep state, so that the UE is in an active state The transmission delay is lower than the transmission delay in which the UE is in a sleep state.

In the current DRX solution, the base station sends a DXR parameter to the communication device managed by itself, to configure the duration of the communication device in the sleep state and the duration of configuring the communication device to be in the active state. Once the communication device accepts the DRX parameter configured by the base station and executes according to the DRX parameter. DRX cannot actively request an extended activation state to reduce the transmission delay.

Summary of the invention

The present application provides a method and apparatus for reducing data reception delay to solve the technical problem that an existing communication device cannot actively request to extend an activation state or stop performing DRX to reduce transmission delay.

In a first aspect, an embodiment of the present application provides a method for reducing a data reception delay, where a communication device sends a request message to a network device, where the request message is used by the network device to determine to send a first message to the communication device, so that the network device receives After the request message, the first message may be sent to the communication device, where the first message is used by the communication device to determine an extended activation state, and the communication device extends the activation state after receiving the first message.

With the above method, the communication device such as the UE may request the network device to extend the duration of the active state, and extend the activation state after receiving the first message sent by the network device, because the user equipment is in the active state when transmitting in the DRX transmission mode. The delay is lower than the transmission delay when the user equipment is in a sleep state, so the method can reduce the transmission delay by extending the duration in which the communication device is in an active state.

In a possible design, the communication device can send a request message to the network device before determining that the duration timer and/or the inactivity timer timer of the self-maintenance timer expires, which can prevent the communication device from timing due to the persistent timer and the inactive state.

The following takes the communication device 101 as the UE as an example to describe the manner in which the communication device 101 performs the DRX: when the DRX is performed, the UE needs to configure the value of the on-time timer maintained by the UE according to the DRX parameter information sent by the network-side device 102 ( For example, the value of the on duration timer in the DRX parameter information is 100, and the UE can configure the on duration timer according to the DRX parameter information to perform the maximum timing of 100 milliseconds and the value of the DRX inactivity timer. The value of the duration timer and the value of the inactivity timer may be indicated by a slot or a number of symbols; the value of the duration timer may be used to indicate that the communication device remains in the active state after entering the active state. The duration, the value of the inactive state timer may be used to indicate the duration of the active state of the communication device after receiving the scheduling signaling of the physical downlink control channel (PDCCH); when the UE performs DRX according to the DRX parameter information, A schematic diagram of the DRX cycle is shown in FIG. 5. When performing DRX, the UE turns on the receiver only when necessary. The activated state, and to receive downlink data signaling, while at other times off the receiver to enter a sleep state, stops receiving downlink data and signaling to save UE power consumption. DRX is divided into idle state DRX and connected state DRX. C-DRX (C-DRX, which is the DRX in the RRC connected state) refers to the DRX feature when the UE is in the RRC connected state. The C-DRX is implemented by monitoring the PDCCH, and the UE (although in the connected state) The UE still enters the sleep state according to the DRX periodically, and the base station considers that the UE is in a sleep state; the base station does not schedule data for the UE in the sleep state, and the UE in the sleep state does not receive the PDCCH; (including the voice service, the UE also performs DRX); the base station only sends the PDCCH to the UE for scheduling when the UE is in the active state (including the time indicated by the on Duration Timer, we define the wake-up window), and the UE also receives the PDCCH sent by the base station in the wake-up window; In the Long DRX cycle window, the UE is in a sleep state except for the on Duration Timer. The base station does not send the PDCCH to the UE for scheduling. In the DRX long cycle, the UE can be in the sleep state except for the time indicated by on duration tiemr. If the UE sends an SR within the long cycle, the UE is in a awake state. The UE starts the timing of the persistent timer each time it enters the active state, and the UE remains in the active state before the duration timer expires (the timing timeout means that the timer count reaches the value configured by the UE), so that the UE can perform the UE. Receiving downlink data and signaling; when the duration of the timer expires, the UE determines whether the inactivity timer is in the timing state, and if the inactivity timer is not in the timing state (the timing is not started or the timeout has expired), the UE may end. The active state enters the sleep state of the DRX. If the inactive state timer is still in the timed state, the UE still needs to remain in the active state until the timeout of the inactive state timer expires, wherein the inactive state timer works, The UE in the active state starts the timing of the inactive state timer every time the PDCCH scheduling signaling is received (or restarts the timing of the inactive state timer, that is, the inactive state timer that has been in the timed state restarts timing) .

For example, the UE may configure a duration timer according to the number of time slots or the number of symbols configured by the network side device 102. For example, the number of time slots configured by the network device 102 for the UE's duration timer is 10, assuming that the current UE 102 is activated. The bandwidth of the bandwidth part (BWP) is 1 millisecond (ms). The duration of the timer from the start of the timer to the timeout is actually 1 ms. If the UE 101 starts the duration of the timer, the duration timer is If the timeout expires after 10 ms, it means that the UE has listened to 10 time slots of the currently activated BWP; for example, the number of symbols configured by the network device 102 for the UE's duration timer is 10, and the current UE activated BWP has a time slot length of 1 ms. If the time slot length of the BWP is seven times the symbol length, that is, the symbol length of the BWP is 0.143 ms, the actual timer duration from the start of the timer to the timing timeout is 1.43 ms, and the timeout occurs after the timer is executed for 1.43 ms. , indicating that the UE has listened to 10 symbols. In the implementation manner, the configuration manner of the inactivity timer can be referred to the manner of configuring the persistent timer in the above example.

If the communication device 101 is a UE, the method for reducing the data reception delay provided by the embodiment of the present application may include the steps shown in FIG. 6:

Step S101: The UE sends a request message to the network device 102, where the request message is used by the network device 102 to determine to send a first message to the UE, where the first message is used by the UE to determine the duration of the activation state when the DRX is discontinuously received.

Step S102: The network device 102 receives the request message sent by the UE.

Step S103: The network device 102 sends a first message to the UE:

Step S104: After receiving the first message, the UE lengthens the duration that the UE is in an active state.

With the above method, the UE can actively send a request message to request to extend the activation state when DRX is performed. After receiving the first message sent by the network device 102, the UE can extend the duration of the activation state of the lower transmission delay, thereby Reduce the transmission delay of the UE.

In the implementation of step S104, the extension of the UE activation state may be implemented by starting or restarting (resetting) the timing of the UE's inactive state timer, specifically, if the UE's current inactivity timer is in the timing state. The UE may reset the inactivity timer to restart the inactivity timer; if the UE's current inactivity timer is not in operation, the UE may cause the inactivity timer to start timing.

According to the foregoing solution, the UE may reduce the transmission delay of the UE, but increase the power consumption of the UE, and enable the UE to determine that the UE enters the low-latency scenario before performing the step shown in S101 above, and/or determine that the UE uses the low-latency service. Therefore, the UE can be prevented from performing the method of reducing the data reception delay according to the method for reducing the data reception delay in the case that the UE does not enter the low-latency scenario and does not use the low-latency service, thereby reducing the power consumption of the UE. It should be noted that the low-latency scenario here includes, but is not limited to, an application scenario in which the UE enters a red packet, robs a train ticket, and performs an online game. In this scenario, the UE needs to be in a low transmission delay state for a long time; Including, but not limited to, calls used by the UE, virtual reality (VR), augmented reality (AR), or ultra-reliable low latency communication (URLLC).

It should be understood that the UE in step S101 sends a request message to the network device 102, including but not limited to one or more of the following: the UE sends a request message to the network device 102 and the request message is successfully sent; the UE prepares to the network device 102. Sending a request message, the request message has not been successfully sent; the UE has triggered the sending of the request message, and the request message has not been successfully sent.

Exemplarily, before step S101, the UE may receive DRX parameter information configured by the network device 102 for the UE, and perform DRX according to the DRX parameter information. Specifically, the network device 102 may send the first DRX parameter information to the UE, where the UE configures at least one of the following according to the first DRX parameter information: a long DRX cycle, an inactive state timer, and a short cycle. A timer (DRX short cycle timer), a hybrid automatic repeat request (HARQ) round trip time (RTT) timer (HARQ RTT timer), and a retransmission timer (DRX retransmission timer), On Duration Timer duration timer.

In an implementation, the UE may further perform the step shown in S101 before determining that the duration timer and/or the inactivity timer expired by the UE is timed out, so that the UE may be prevented from extending the activation state according to the method shown in steps S101 to S104. The sleep state occurs due to the duration timer and the inactivity timer expired.

Specifically, before step S101, the UE may determine that the duration timer maintained by itself does not time out, and/or determine that the inactive state timer maintained by itself does not time out; or, the UE may also determine the duration timer maintained by itself. In the case that the inactive state timer is not timed out, and the inactive state timer that is determined to be maintained by itself is not timed out, the step shown in S101 is performed; or the UE may also be in the inactive state timer maintained by itself or not. In the case of being in the timed state and determining that the continuous timer maintained by itself has not timed out, the step shown in S101 is performed.

It should be understood that the embodiment of the present application does not limit the UE to perform the step shown in S101 after determining that the duration timer and/or the inactivity timer of the self-maintenance timer expires, for example, even if the UE has determined the duration timer and the inactive state timer. The timer of the device times out, and the UE can still perform the steps shown in the above S101 to reduce the transmission delay. For example, after the duration timer expires, the UE may perform the step shown in S101 if it is determined that the duration of the duration timer has expired is less than N times the duration indicated by the value of the UE configured for the duration timer. , N may be 3, 2, or 1.5; the UE may also determine, after the inactivity timer, that the duration of the inactivity timer has expired is less than the duration of the timer represented by the value of the UE configured for the inactive timer. In the case of multiples, the steps shown in S101 are performed, where N may be 3, 2 or 1.5. In the above manner, even if the timer of the persistent timer and/or the inactivity timer expires, the UE can be activated for a period of time after performing the steps shown in S101 to S104 to reduce the transmission delay.

Exemplarily, in the implementation of step S101, when sending a request message to the network device 102, the UE may generate uplink data through a higher layer (such as through an application layer), and trigger a modem of the UE based on the generated uplink data. The module sends a request message; or the UE may trigger the modem module to send the request message through an application processor (AP) module; or the user equipment may directly send the request message through the modem module. In an implementation, the UE may also trigger the sending of the SR by sending an IP (Internet Protocol) packet to the designated one or more servers.

In the implementation of the step S101, the request message sent by the UE to the network device 102 is a scheduling request (SR), and the SR may be used to request an uplink resource, where the uplink resource may be used by the UE to send uplink data, and the network device 102 receives the uplink data. After the SR, the PDCCH scheduling signaling may be sent to the UE for indicating the uplink resource to the UE, and the UE may restart the timing of the inactive state timer after receiving the PDCCH scheduling signaling, thereby extending the time duration of the inactive timer. It is not active until the timer of the active state timer expires.

As shown in FIG. 7, a method for reducing data reception delay provided by an embodiment of the present application may include the following steps:

Step 701: The network device 102 sends the first DRX information to the UE. The first DRX information is used to configure the UE to perform DRX.

Step 702: After receiving the first DRX parameter information sent by the network device 102, the UE performs DRX according to the first DRX parameter information.

Step 703: The UE determines to enter the low-latency scenario and/or the UE determines to use the low-latency service. For example, after receiving the downlink red-packet data, the UE may determine to enter the low-latency red-strap scenario; the low-latency service may be the call. Business and so on;

Step 704: The UE determines that the duration of the duration timer and/or the inactivity timer maintained by itself is not timed out;

Step 705: The UE sends an SR to the network device 102.

Step 706: After receiving the SR sent by the UE, the network device 102 sends PDCCH scheduling signaling to the UE, and starts or restarts the inactive state timer maintained by the network device 102, and the timer of the inactive state timer maintained by the network device 102. Before the timeout, the network device 102 determines that the UE is in an active state;

Step 707: After receiving the PDCCH scheduling signaling sent by the network device 102, the UE starts or restarts the timing of the inactive state timer, and keeps the active state before the timeout of the inactive state timer expires, and then ends the process.

With the above method, the UE may actively send the PDCCH scheduling signaling to the UE to indicate the uplink resource by sending the SR to the network device 102, and the UE may start (or restart) the inactive state by receiving the PDCCH scheduling signaling. The timing of the timer is extended to prevent the UE from entering the DRX sleep state, and the downlink data cannot be received in the low latency scenario and/or the low latency service cannot be used. The network device 102 can also start after sending the PDCCH scheduling signaling to the UE. (or restart) the timing of the inactive timer.

In the implementation of step S101, the UE may further carry the second DRX parameter information in the request message sent to the network device 102, where the second DRX parameter information is different from the first DRX parameter information previously received by the UE, and thus, step S103 The medium network device 102 may send a first message to the UE to indicate that the network device 102 agrees to configure the second DRX parameter information for the UE. For example, the first message may carry a specific bit, and the UE may receive the first message carrying the specific bit. Performing DRX according to the second DRX parameter information; or the network device 102 may also carry the second DRX parameter information in the first message to indicate that the second DRX parameter information is agreed to be configured for the UE; in implementation, the network device 102 sends the message to the UE. The first message may be a radio resource control (RRC) message;

The second DRX parameter information may indicate that the UE does not enter the sleep state, so that the UE may remain in the active state without entering the sleep state. For example, the second DRX parameter information may include at least one of the following: used to indicate that the UE does not Information for using the DRX mechanism, information for indicating that the UE does not enter the sleep mode during the long DRX cycle, for indicating that the long DRX cycle is set to 0; wherein the information indicating that the UE does not use the DRX mechanism may include indicating that the UE is not used Time information of the DRX mechanism, for example, information indicating that the UE does not use the DRX mechanism, including information indicating that the UE does not use the DRX mechanism within 60 minutes;

The second DRX parameter information may also indicate that the UE performs a shorter long DRX cycle. For example, the second DRX parameter information carries information indicating a length of the long DRX cycle, and the length of the long DRX cycle is less than the length. The length of the long DRX cycle indicated by a DRX parameter information;

The second DRX parameter information may also indicate that the UE performs a shorter short DRX cycle. For example, the second DRX parameter information carries information indicating a length of the short DRX cycle, and the length of the short DRX cycle is greater than the length. The length of the short DRX cycle indicated by a DRX parameter information;

Additionally, the second DRX parameter information may also indicate that the UE increases the maximum timing of the duration timer and/or increases the maximum timing of the inactivity timer. For example, the second DRX parameter information carries information indicating a value of the duration timer, the value of the duration timer being greater than the value of the duration timer indicated by the first DRX parameter information; the second DRX parameter information may also be carried for Information indicating the value of the inactivity timer, the value of the inactivity timer being greater than the value of the inactivity timer indicated by the first DRX parameter information.

In another implementation manner, after the UE sends the second DRX parameter information to the network device 102, if the network device 102 does not agree to configure the second DRX parameter information for the UE, the network device 102 may further configure a new DRX for the UE. The parameter information indicates that the UE performs DRX according to the new DRX parameter information by using the first message to extend the activation state of the UE, where the new DRX parameter information configured by the network device 102 for the UE is different from the second DRX parameter information. Specifically, the network device 102 may carry the third DRX parameter information in the first message in the execution of S103, so that after receiving the first message, the UE performs DRX according to the third DRX parameter information. In an implementation, the first message sent by the network device 102 to the UE may be an RRC message.

The third DRX parameter information may indicate that the UE does not enter the sleep state, so that the UE may remain in the active state without entering the sleep state. For example, the third DRX parameter information may include at least one of the following: used to indicate that the UE does not Information for using the DRX mechanism, information for indicating that the UE does not enter the sleep mode during the long DRX cycle, for indicating that the long DRX cycle is set to 0; wherein the information indicating that the UE does not use the DRX mechanism may include indicating that the UE is not used Time information of the DRX mechanism;

The third DRX parameter information may also indicate that the UE performs a shorter long DRX cycle. For example, the third DRX parameter information carries information indicating a length of the long DRX cycle, where the length of the long DRX cycle is smaller than the first DRX parameter information. The length of the indicated long DRX cycle;

The third DRX parameter information may also indicate that the UE performs a longer short DRX cycle. For example, the third DRX parameter information carries information indicating a length of the short DRX cycle, where the length of the short DRX cycle is greater than the first DRX parameter information. The length of the indicated short DRX cycle;

Additionally, the third DRX parameter information may also indicate that the UE increases the maximum timing of the duration timer and/or increases the maximum timing of the inactivity timer. For example, the third DRX parameter information carries information indicating a value of the duration timer, the value of the duration timer being greater than the value of the duration timer indicated by the first DRX parameter information; the third DRX parameter information may also be carried for Information indicating the value of the inactivity timer, the value of the inactivity timer being greater than the value of the inactivity timer indicated by the first DRX parameter information.

As shown in FIG. 8, a method for reducing data reception delay provided by an embodiment of the present application may include the following steps:

Step 801: The network device 102 sends the first DRX information to the UE. The first DRX information is used to configure the UE to perform DRX.

Step 802: After receiving the first DRX parameter information, the UE performs DRX according to the first DRX parameter information.

Step 803: The UE determines to enter the low-latency scenario and/or the UE determines to use the low-latency service. For example, after receiving the downlink red-packet data, the UE may determine to enter the low-latency red-strap scenario; the low-latency service may be the call. Business and so on;

Step 804: The UE determines that the duration of the sustained timer and/or the inactive state timer maintained by itself is not timed out;

Step 805: The UE sends a request message to the network device 102, where the request message carries the second DRX parameter information.

Step 806: After receiving the request message sent by the UE, the network device 102 sends a first message to the UE. In an implementation, the first message may be used to indicate that the network device 102 agrees to configure the second DRX parameter information for the UE, or the first message. The third DRX parameter information configured by the network device 102 for the UE may be carried;

Step 807: After receiving the first message sent by the network device 102, the UE performs DRX according to the second DRX parameter information. Alternatively, the UE performs DRX according to the third DRX parameter information carried in the first message.

With the above method, the UE may request the network device 102 to configure the second DRX parameter information to reduce the duration of the data receiving delay. The network device 102 may send the first message indicating the consent to the UE, or may be carried as the UE in the first message. The third DRX parameter information is configured, and the UE may perform DRX according to the second DRX parameter information or the third DRX parameter information to implement extension of the activation state.

In another implementation manner of step S101, the UE may also notify the network device 102 that the DRX capability of the UE is not supporting DRX by using a request message sent to the network device 102. For example, the UE sends the DRX capability indicating that the UE is the network device 102 to The request message of the DRX is not supported, so that the UE can no longer enter the sleep state from the active state according to the first message sent by the network device 102, the first message can be used to indicate that the UE does not perform DRX, and the network device 101 can be in the UE. After the first message is sent, it is determined that the UE does not enter the sleep state. Therefore, after receiving the downlink data that needs to be sent to the UE, the network device 102 can perform downlink transmission to the UE, so that it is no longer necessary to wait for the UE to enter the active state from the sleep state, which is reduced. Transmission delay.

Specifically, the request message sent by the UE to the network device 102 may be a registration request for the UE to access the network, where the registration request may carry information indicating that the DRX capability of the UE is not supporting DRX; The message may be specifically used to indicate that the UE does not configure at least one of the following: a long DRX cycle, a persistent timer, an inactive timer, a short cycle timer, a hybrid automatic repeat request loopback timer, or a retransmission timer Device. In an implementation, in the registration request sent by the network device 102, the bit position corresponding to the DRX command MAC control element may be set to 0 to indicate that the DRX capability of the UE is not supporting DRX.

Exemplarily, before sending the foregoing registration request to the network device 102, the UE may further determine that the time interval from the sending time of the first registration request has reached a preset duration, where the first registration request is a registration request previously sent by the UE, the first The DRX capability of the UE indicated by the registration request is different from the DRX capability indicated by the registration request sent by the UE to the network device 102 in step S101. For example, the first registration request may carry information indicating that the UE supports DRX. For example, the preset duration can be set to 24 hours, or 60 minutes, or ten minutes to avoid frequent modification of the UE's DRX capability.

As shown in FIG. 9, a method for reducing data reception delay provided by an embodiment of the present application may include the following steps:

Step 901: The UE sends a first registration request to the network device 102, and carries information indicating that the UE supports DRX. In an implementation, the UE may determine and record the time for sending the first registration request.

Step 902: After completing registration of the UE, the network device 102 sends the first DRX information to the UE; the first DRX information is used to configure the UE to perform DRX;

Step 903: After receiving the first DRX parameter information, the UE performs DRX according to the first DRX parameter information.

Step 904: The UE determines to enter the low-latency scenario and/or the UE determines to use the low-latency service. For example, after receiving the downlink red-packet data, the UE may determine to enter the low-latency red-strap scenario; the low-latency service may be the call. Business and so on;

Step 905: The UE determines that the duration of the duration timer and/or the inactivity timer maintained by itself does not time out;

Step 906: The UE sends a registration request to the network device 102, where the registration request carries information indicating that the UE does not support DRX.

Step 907: After receiving the registration request sent by the UE, the network device 102 sends a message to the UE for instructing the UE not to perform the DRX first message.

Step 908: After receiving the first message sent by the network device 102, the UE does not enter the sleep state.

With the above method, the UE may request the network device 102 to perform re-registration of the UE, and instruct the UE not to perform DRX by re-registering the other network device 102, so that the UE no longer enters the sleep state from the active state, thereby realizing the extension of the activation state.

In another method for reducing data reception delay provided by the embodiment of the present application, the UE performing DRX by using the first discontinuous reception DRX parameter information configured according to the network device, multiple times to the network within a preset first duration The device 102 sends a scheduling request SR, which is used to request the network device 102 to configure an uplink resource for the UE. The time interval between any two consecutive transmissions of the SR is determined according to the value of the inactive state timer, and the network device receives each time. After the SR is sent, the PDCCH scheduling signaling is sent to the UE. After receiving the PDCCH scheduling signaling, the UE starts or restarts the inactive state timer maintained by the UE, and remains in the inactive timer before the timer expires. The activation state; in an implementation, the network device 102 may also start or restart the timing of the inactive state timer maintained by itself after each time the PDCCH scheduling signaling is sent, and determine before the timeout of the inactive state timer expires. The UE is in an active state. For example, the first duration may be a preset duration, for example, may be 1000 ms, 60 minutes, etc., and may be determined according to a low transmission delay scenario entered by the communication device or a delay requirement of the performed low transmission delay service. For a long time.

In an implementation, after the communication device determines to enter the low-latency scenario and/or uses the low-latency service, the scheduling request SR is sent to the network device 102 multiple times within a preset first duration to save communication device power consumption. .

In an implementation, the time interval may be determined according to the maximum timing of the inactive state timer, and the time interval when the SR is transmitted any two times may be different. For example, if the maximum value of the inactivity timer is 100 (the unit can be s seconds, ms milliseconds, or subframe, or slot time slot, or symbol), we take ms as an example. For example, the UE may send the SR once in the first time period after about 100 ms. For example, the UE may send an SR after 130 (ie, 100+30) ms, and then pass 70 again (ie, 100-30). After the ms time, the next SR is sent; for example, the UE may send an SR after 120 (ie, 100+20) ms, or send an SR after 80 (ie, 100-20) ms.

In another embodiment, the time interval may be less than the maximum timing of the inactive state timer. For example, the maximum timing of the inactive state timer is 100 ms, and the user equipment may send an SR over a time interval of less than 100 ms, for example, the time interval is 80 or 90 ms, so that the UE can not enter the sleep state, or less time is in the sleep state.

In another embodiment, the time interval may also be greater than or equal to the maximum timing of the inactive state timer. For example, the time interval may be greater than the maximum timing of the inactive state timer maintained by the communication device and less than N times the maximum timing, N being 3, 2, or 1.5.

For example, if the maximum timing of the inactivity timer is 100 ms, the UE may wait for an interval of more than 100 ms and less than 300 ms to transmit one SR at a time; or, the UE sends an SR every time interval of more than 100 ms and less than 150 ms. Therefore, the UE may be in a waking state for a period of time in the DRX long cycle (excluding the time indicated by the on durationtimer) to reduce the receiving delay of the UE. Otherwise, the UE will be in the DRX long cycle (excluding the time indicated by the on durationtimer). Both are in a dormant state.

In a feasible implementation manner, the time interval between the communication device transmitting the SRs in any two consecutive times is a preset duration, so that the communications device can send a scheduling request to the network device every preset time in the first time duration. SR, for example, if the maximum timing of the inactivity timer is 100 ms, the preset duration may take 80 ms, so that the communication device can transmit one SR every 80 ms in the first duration.

Exemplarily, the embodiment of the present application further provides a method for extending a wake-up state, which is applied to a user equipment, including:

The user equipment determines that the on duration timer duration timer and/or the inactivity timer activity timer expires or times out or after a timeout;
