[0002] In the existing technology, in order to extend the standby time of the terminal, a discontinuous reception (DRX) cycle or eDRX cycle is set. Since the DRX cycle or eDRX cycle is long, it will cause a large paging delay and cannot be applied to services that require both low latency and long standby time. For example, in an automatic fire alarm detection and fire extinguishing system, from the time the sensor detects a fire, it is necessary to complete the closing of the fire shutter door and the opening of the automatic fire extinguisher in a short time. In this scenario, a long paging cycle is not applicable.

[0003] That is, the long paging cycle in the prior art can reduce power consumption, but the wake-up delay is long. Summary of the Invention

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0025] The wake-up method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0026] See Figure 2 , Figure 2 This is a flowchart of a wake-up method provided in an embodiment of the present application, the wake-up method comprising:

[0027] Step 201: The first module of the terminal obtains a wake-up signal.

[0028] The first module may be a wake-up signal receiving module of the terminal. The wake-up signal includes at least one of the following: identification information of the terminal; identification information of the group to which the terminal belongs.

[0029] Step 202: When the first target time is outside the paging time window PTW of the first discontinuous reception DRX cycle, trigger the second module to switch to the idle state, wherein the first target time is determined according to the time when the first module obtains the wake-up signal, and the first DRX cycle includes the PTW.

[0030] When the first module receives the wake-up signal, if the first target time is outside the paging time window (PTW) of the first DRX cycle, the second module is triggered to switch to the idle state. The first DRX cycle can be understood as an eDRX (extended discontinuous reception) cycle. The first DRX cycle may include one PTW, and one PTW may include multiple second DRX cycles.

[0031] The first target time may be the time when the first module receives the wake-up signal, or the first target time may be the time when the first module receives the wake-up signal, and the terminal decodes the wake-up signal and determines the triggering time for triggering the second module to switch. Alternatively, the first target time may be the next time after a preset time period starting from the time when the first module receives the wake-up signal. The specific setting can be based on actual conditions and is not limited here. The second module may be the data transmission module of the terminal.

[0032] It should be noted that the second module is in an idle state, which means that the second module is awakened. When the second module is in an idle state, the second module can monitor the paging signal.

[0033] In this embodiment, a first module of a terminal receives a wake-up signal; and when a first target time is outside the paging time window (PTW) of a first discontinuous reception (DRX) cycle, the terminal triggers the second module to switch to an idle state, wherein the first target time is determined based on the time when the first module receives the wake-up signal, and the first DRX cycle includes the PTW. In the above description, at a time outside the PTW of the first DRX cycle, the terminal triggers the second module to switch to an idle state, i.e., awakens the second module using the wake-up signal. This can shorten the wake-up latency of the second module and meet the low-latency requirement for data transmission.

[0034] During the time outside the PTW of the first DRX cycle, the second module is in a dormant state. If the terminal triggers a switch of the second module, the second module switches from the dormant state to the idle state. While in the dormant state, the second module does not monitor paging messages. The dormant state can also be called a sleep state. The dormant state of the second module can save power consumption.

[0035] In one embodiment of the present application, the above-mentioned wake-up method further includes: when the second module is in an idle state, the terminal controls the second module to monitor the paging message according to the second DRX cycle.

[0036] In one embodiment of the present application, the above-mentioned wake-up method also includes: the terminal controls the second module to start monitoring the paging message according to the second DRX cycle at a second target time; the second target time is the switching completion time when the second module switches to the idle state.

[0037] If the first target time is the time when the first module receives the wake-up signal, the second target time can be the time after the first target time. Since it takes time for the second module to switch from the sleep state to the idle state after receiving the wake-up signal, the time period between the first target time and the second target time can be used for the second module to switch.

[0038] In one embodiment of the present application, the above-mentioned wake-up method further includes: when the second module is in an idle state, the terminal controls the second module to perform radio resource management (Radio Resource Management, RRM) measurement in the second DRX cycle.

[0039] In one embodiment of the present application, the method further includes: the terminal controlling the second module to monitor the paging message in a second DRX cycle within a PTW of the first DRX cycle, where the PTW includes a plurality of the second DRX cycles.

[0040] That is to say, within the PTW of the first DRX cycle, the terminal controls the second module to listen to the paging message in the second DRX cycle within the PTW; outside the PTW of the first DRX cycle, the terminal wakes up the second module based on the wake-up signal, triggers the second module to switch to the idle state, and within the time outside the PTW of the first DRX cycle, with the second target time as the starting time, listens to the paging message according to the second DRX cycle.

[0041] By configuring the eDRX cycle for the second module (also known as the main communication module), the second module monitors the paging occasion (PO) during each DRX cycle and performs RRM measurements. If downlink traffic arrives during the time period between the PTWs of two eDRX cycles, the main communication module can be awakened by the first module (also known as the low-power wake-up module), thereby achieving low power consumption while reducing the wake-up latency of the second module. Furthermore, the main communication module performs RRM measurements according to the eDRX cycle configuration, enabling the terminal to perform resource and mobility management.

[0042] The following is an example of the wake-up method provided in this application.

[0043] The eDRX cycle is configured for the second module of the terminal. The first module can wake up the second module at a position other than PTW in each eDRX cycle of the second module. When not woken up by the first module at the position, the first module is in a dormant state.

[0044] like Figure 3 As shown in the figure, label a indicates a DRX cycle within the PTW, label b indicates an eDRX cycle, and label c indicates the time outside the PTW of the eDRX cycle. The second module is in a dormant state during the time indicated by label c. If the first module receives a wake-up signal during the time indicated by label c, it can trigger the second module to switch to an idle state and wake up the second module; label d indicates the PO within the DRX cycle. The second module monitors the paging message once in each DRX cycle within the PTW of each eDRX cycle, and the second module performs RRM measurement within the PTW. According to the configuration of the second module, the measurement reference signal includes but is not limited to the synchronization signal block (Synchronization Signal Block, abbreviated as SSB). The terminal can perform RRM management and mobility management based on the measurement value of the measurement reference signal.

[0045] When downlink data arrives outside the PTW, the transmitter can send a wake-up signal at any time as needed. Upon receiving the wake-up signal, the first module triggers the second module to switch to the idle state. After switching from the dormant state to the idle state, the second module monitors paging messages according to the DRX cycle and further performs RRM measurements.

[0046] The first module receives a wake-up signal and triggers the second module to switch to an idle state. When downlink data arrives, the first module detects the wake-up signal sent by the transmitter and determines that the wake-up signal contains information to wake up the terminal, such as the identification information of the terminal or the identification information of the group to which the terminal belongs. The first module then triggers the second module to switch from the sleep state to the idle state. The second module monitors paging messages according to the DRX cycle. The second module can also perform RRM measurements. The second module is in a dormant state when it is not awakened by the first module. After the first module triggers the second module to switch, the first module can switch from the working state to the closed state.

[0047] like Figure 4As shown in the figure, the eDRX period configured by the base station for the second module of the terminal is 17.92ms, the length of PTW is 5.12ms, and the DRX period is 1.28ms. At time t1, the terminal receives a wake-up signal sent by the base station. The wake-up signal contains information for waking up the terminal, such as the identification information of the terminal, or the identification information of the group to which the terminal belongs. The first module detects the information of the terminal included in the wake-up signal and triggers the second module to switch from the sleep state to the idle state. Since the switching of the second module takes time, the second module is a time offset after the wake-up moment (i.e., the moment when the first module receives the wake-up signal), as shown in the figure. Figure 4 In the example, at the time t2, the paging message is monitored according to the 1.28ms DRX cycle, and subsequent data transmission is performed according to the received paging message. In addition, the first module can also perform RRM measurement.
