Description

Wake-up method and apparatus

[0001] The present application claims priority to the Chinese patent application No. 202410889523.X, filed on July 3, 2024, entitled “Wake-up method and apparatus”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a wake-up method and apparatus. BACKGROUND

[0003] The wake-up radio (WUR) technology refers to that when a main radio (MR) of a terminal is in a sleep state or is powered off, only a low-power radio (LR) is turned on to monitor a low power wake-up signal (LP-WUS), and after the LR receives the LP-WUS, the MR is woken up.

[0004] As shown in FIG. 1, when a network device pages a terminal in a cell, if the MR of the terminal is in a sleep state, the network device needs to first wake up the MR of the terminal through an LP-WUS signal, and then the terminal performs physical downlink control channel (PDCCH) blind detection based on the MR to determine scheduling information, receives a physical downlink shared channel (PDSCH) according to a time-frequency resource indicated by the scheduling information, and reads a terminal identifier carried in the PDSCH to determine whether the terminal is a target terminal that needs to be woken up by the network device. If it is determined that the terminal is the target terminal that needs to be woken up by the network device, the terminal can further receive a paging (Paging) message from the network device. However, since the LP-WUS signal is broadcast, the terminals that do not belong to the target terminals that need to be woken up by the network device will also receive the LP-WUS signal. After receiving the LP-WUS signal, these terminals need to perform PDCCH blind detection, further read the terminal identifier carried in the PDSCH, and then determine that they are not the target terminals that need to be woken up by the network device according to the terminal identifier carried in the PDSCH. In this way, the power consumption of the terminal is wasted, thereby affecting the performance of the terminal. SUMMARY

[0005] The present application provides a wake-up method and apparatus, which is beneficial to save the power consumption of the terminal.

[0006] In a first aspect, the present application provides a wake-up method, which can be executed by a terminal-side device (e.g., a first terminal). The terminal-side device can be a terminal device or a processor, a module, a chip, a chip system, or a functional module, etc. implementing the method. The method comprises: receiving a first wake-up signal, the first wake-up signal carrying an identifier of a first group; if the first terminal belongs to the first group, receiving a second wake-up signal, the second wake-up signal carrying a first identifier of a target terminal to be woken up; and if the first identifier of the first terminal is carried in the second wake-up signal, switching the first terminal from a sleep state to a wake-up state.

[0007] In the method described in the first aspect, the target terminal belonging to the first group is woken up by combining the first wake-up signal and the second wake-up signal. The first wake-up signal carries an identifier of a first group, i.e., a group to which the target terminal to be woken up by the network device belongs. The first terminal can first determine whether it belongs to the group to which the target terminal to be woken up by the network device belongs according to the first wake-up signal. If the first terminal does not belong to the first group, the first terminal can continue to remain in the sleep state and can not need to receive the second wake-up signal, thereby saving power consumption. In the case where the first terminal belongs to the first group, the first terminal receives the second wake-up signal, and the second wake-up signal carries a first identifier of the target terminal to be woken up. The first terminal can determine whether it is the target terminal to be woken up by the network device in the first group according to the second wake-up signal. If the second wake-up signal does not carry the first identifier of the first terminal, the first terminal can continue to remain in the sleep state, thereby saving power consumption. If the second wake-up signal carries the first identifier of the first terminal, the first terminal is woken up and can further receive uplink and downlink data from the network device. Therefore, by combining the first wake-up signal and the second wake-up signal, the network device can more accurately wake up the target terminal, avoid waking up non-target terminals for blind detection, waste the power consumption of non-target terminals, and thus help save the power consumption of the terminal.

[0008] In a possible implementation, before receiving the second wake-up signal from the network device, the method further comprises: receiving first configuration information from the network device, the first configuration information including configuration information of the second wake-up signal; and the configuration information of the second wake-up signal includes one or more of the following: a time domain resource position where the second wake-up signal is located; a frequency domain resource position where the second wake-up signal is located; and a number of information bits carried by the second wake-up signal.

[0009] In a possible implementation, the first identifier of the first terminal is related to one or more of the following parameters: a terminal identifier (ue_id) of the first terminal, a signal measurement value of the first terminal, an area where the first terminal is located, or a frequency point of the first terminal.

[0010] In a possible implementation, the receiving the first wake-up signal further can be implemented as: performing signal measurement on the first wake-up signal sent by the network device through multiple beams, determining a first beam in the multiple beams, the first beam being a beam with the strongest signal in the multiple beams; and the receiving the second wake-up signal further can be implemented as: receiving the second wake-up signal from the network device at a position corresponding to the first beam. Based on this implementation, the power consumption of the first terminal is reduced.

[0011] In a possible implementation, the method further includes: sending first indication information to the network device, the first indication information indicating the first beam. Based on this implementation, the network device can use the first beam to send the second wake-up signal according to the first indication information, so as to reduce the power consumption of the network device.

[0012] In a possible implementation, the second wake-up signal can be a periodic signal, an aperiodic signal, or a semi-persistent signal.

[0013] Optionally, the second wake-up signal is a semi-persistent signal. Further optionally, before receiving the second wake-up signal from the network device, the method further includes: receiving second indication information from the network device, the second indication information indicating that the second wake-up signal is activated, or the second indication information indicating that the network device sends the second wake-up signal in a first time window. Alternatively, further optionally, the first wake-up signal indicates that the second wake-up signal is activated, or the first wake-up signal indicates that the network device sends the second wake-up signal in the first time window.

[0014] Optionally, the second wake-up signal is a periodic signal. Further optionally, a period of the first wake-up signal is less than or equal to a period of the second wake-up signal.

[0015] In a possible implementation, the first wake-up signal and the second wake-up signal are both low-power wake-up signals.

[0016] In a possible implementation, the switching of the first terminal from the sleep state to the wake-up state can be implemented as: switching a main radio of the first terminal from the sleep state to the wake-up state.

[0017] In a second aspect, the present application provides a wake-up method, which can be executed by a network-side device. The network-side device can be a network device, or a processor, a module, a chip, or a chip system or a functional module, etc. implementing the method. The method includes: sending a first wake-up signal, the first wake-up signal carrying an identifier of a first packet; and sending a second wake-up signal, the second wake-up signal carrying a first identifier of a target terminal that needs to be woken up in the first packet.

Further optionally, before the second wake-up signal is sent, the method further includes: sending second indication information, the second indication information indicating that the second wake-up signal is activated, or the second indication information indicating that the network device sends the second wake-up signal in the first time window. Alternatively, further optionally, the first wake-up signal indicates that the second wake-up signal is activated, or the first wake-up signal indicates that the network device sends the second wake-up signal in the first time window.

[0023] Optionally, the second wake-up signal is a periodic signal. Further optionally, a period of the first wake-up signal is less than or equal to a period of the second wake-up signal.

[0024] In a possible implementation manner, the first wake-up signal and the second wake-up signal are both low-power-consumption wake-up signals.

[0057] The method provided in the embodiments of the present application can be applied to two entities in a communication system, for example, one of the two entities can send information to the other entity, or receive information sent by the other entity. In a wireless communication system, communication devices are included, and the communication devices can perform wireless communication by using air interface resources. The air interface resources can include at least one of a time domain resource, a frequency domain resource, a code resource, and a space resource, which are not limited in the present application. For example, the two entities mentioned above can include a network device and a terminal device, or a chip that can be placed in a network device, and a chip that can be placed in a terminal device, and the like. Of course, with the development of standards, other types of entities may also appear in the future, which are not limited in the embodiments of the present application.

[0058] FIG. 2 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. As shown in FIG. 2, the communication system can include at least one network device and at least one terminal device, such as terminal device 1 to terminal device 4 in FIG. 2. The terminal device and the network device can communicate with each other through an air interface Uu link or an NTN link, etc. For example, terminal device 3 and terminal device 4 can communicate with each other through a D2D sidelink, etc. The form of the terminal device shown in FIG. 2 is only an example. In a specific implementation, the terminal device can also include a vehicle-mounted device or a vehicle-mounted terminal in a vehicle network, etc. The embodiments of the present application do not limit the specific form of the terminal device when it is applied to a vehicle network or the Internet.

[0059] FIG. 3 is a schematic diagram of another architecture of a communication system according to an embodiment of the present application. Taking a network device named base station as an example, the present application can be applied to a scenario where a super base station (super BS) and a ground base station exist at the same time. The super base station can also be referred to as an anchor base station (anchor BS).

[0060] The super base station can be a satellite, a high altitude platform station (HAPS), an air balloon station, a drone station, a broadcast station, etc. The super base station and the ground base station can be connected through an optical fiber or wireless transmission. The ground base station can be a cellular station in the communication system, such as a macro station, a small station, a micro station, etc. or other implementation manners. The super base station has the functions of providing network services for terminal devices and managing and controlling base stations, such as waking up or shutting down a certain ground base station. The terminal devices in the network area covered by the super base station can access the super base station to obtain network services through the super base station, or can access the ground base station under the super base station. Generally, the super base station provides network coverage services for terminal devices, and the ground base station provides capacity services for terminal devices. Therefore, the signal coverage area of the super base station is generally larger than that of the ground base station, and the signal coverage area of the super base station and the signal coverage area of the ground base station have an intersection.

[0061] The terminal device and the network device are described in detail below.

[0062] A terminal device is a device with wireless transceiver function, which is referred to as terminal below. The terminal can communicate with an access network device (or also referred to as access device or network device shown below) in a radio access network (RAN). The terminal can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device, etc. In a possible implementation, the terminal can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; or can be deployed on water, including a ship; or can be deployed in the air, such as an airplane, balloon or satellite, etc. In another possible implementation, the terminal can be a handheld device, vehicle-mounted device, wearable device, sensor, terminal in Internet of Things, terminal in Internet of Vehicles, unmanned aerial vehicle, terminal in 5G network or future network with wireless communication function, etc. The embodiments of the present application do not limit this. In yet another possible implementation, the terminal can also be a virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in unmanned driving, wireless terminal in remote medical treatment, wireless terminal in smart power grid, wireless terminal in smart city, or wireless terminal in smart home, etc.

[0063] In the embodiments of the present application, the apparatus for implementing the function of the terminal can be a terminal; or can be an apparatus capable of supporting the terminal to implement the function, such as a chip system. The apparatus can be installed in the terminal or used in matching with the terminal. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. For ease of description, the apparatus for implementing the function of the terminal is taken as an example of UE to describe the technical solutions provided by the embodiments of the present application.

[0064] The network device can be a device deployed in a wireless access network to provide wireless communication services for terminals. The network device can also be referred to as an access network device, an access device, or a RAN device, etc. An exemplary network device can be a super base station or a ground base station shown in FIG. 2. As another example, the network device can be a next generation node B (gNB), a next generation evolved node B (ng-eNB), or a network device in 6G communication, etc. The network device can be any device with wireless transceiver function, including but not limited to the base stations shown above (including base stations deployed on satellites). The network device can also be a device with base station function in 6G. As an example, the network device can be an access node, a wireless relay node, a wireless backhaul node, etc. in a wireless fidelity (Wi-Fi) system. As another example, the network device can be a wireless controller in a cloud radio access network (CRAN) scenario. As yet another example, the network device can be a wearable device or a vehicle-mounted device, etc. that can provide wireless communication services. As yet another example, the network device can also be a small station, a transmission reception point (TRP), or a transmission point (TP), etc. In different wireless access technology systems, the names of devices with network device functions may be different, and the embodiments of the present application will not be listed one by one.

[0065] The network device can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, the helicopter or the drone can be configured to act as a device that communicates with another network device.

[0066] In some deployments of a network device, the network device can include a central unit (CU) and a distributed unit (DU), etc. For example, part of protocol layers of the network device are placed in the CU for centralized control, and the rest or all of the protocol layers are distributed in the DU, which is controlled by the CU. In some other deployments of the network device, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In yet some other deployments of the network device, the network device can also be an open radio access network (ORAN) architecture. When the network device is the ORAN architecture, the network device can be a functional entity or a module in the ORAN, etc. For example, the network device can be a combination of one or more of a CU, a DU, or a RU. In the ORAN system, the CU can also be referred to as an open (O)-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, etc. The deployment manners of the network device listed herein are only examples, and as the standard technology evolves, there can be other deployment forms of the network device, which are not limited by the embodiments of the present application.

[0067] In some deployments, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes implement part of the functions of the access network, respectively. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or a RU, etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a base band unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0068] The RAN node can support one or more types of fronthaul interfaces, different fronthaul interfaces respectively corresponding to DUs and RUs having different functions. If the fronthaul interface between the DU and the RU is a common public radio interface (CPRI), the DU is configured to implement one or more of the baseband functions, and the RU is configured to implement one or more of the radio frequency functions. If the fronthaul interface between the DU and the RU is another interface, relative to the CPRI, one or more of the partial baseband functions of the downlink and / or uplink, such as, for the downlink, precoding, digital beamforming (BF), or one or more of inverse fast Fourier transform (IFFT) / adding a cyclic prefix (CP), is moved from the DU to the RU for implementation, and for the uplink, one or more of digital beamforming (BF), or one or more of fast Fourier transform (FFT) / removing a cyclic prefix (CP) is moved from the DU to the RU for implementation. In a possible implementation, the interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the splitting manner between the DU and the RU is different, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, and F.

[0069] Taking the eCPRI Cat A as an example, for downlink transmission, the splitting is layer mapping, the DU is configured to implement one or more of the functions before the layer mapping (i.e., one or more of encoding, rate matching, scrambling, modulation, and layer mapping), and other functions after the layer mapping (e.g., one or more of resource element (RE) mapping, digital beamforming, or IFFT / adding a CP) are moved to the RU for implementation. For uplink transmission, the splitting is RE demapping, the DU is configured to implement one or more of the functions before the demapping (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, and RE demapping), and other functions after the demapping (e.g., one or more of digital BF or FFT / CP removal) are moved to the RU for implementation. It can be understood that the function description of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, and will not be described here.

[0070] In a possible design, a processing unit in the BBU for implementing baseband functions is referred to as a base band high (BBH) unit, and a processing unit in the RRU / AAU / RRH for implementing baseband functions is referred to as a base band low (BBL) unit.

[0071] In different systems, the CU (or CU-CP and CU-UP), DU, or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0072] The network device and / or the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; and can also be deployed on aircraft, balloons, and satellites in the air. The scenario in which the network device and the terminal are located is not limited in the embodiments of this application. In addition, the terminal and the network device can be hardware devices, or software functions running on special-purpose hardware, general-purpose hardware, such as virtualized functions instantiated on a platform (for example, a cloud platform), or entities including special-purpose or general-purpose hardware devices and software functions. The specific form of the terminal and the network device is not limited in this application.

[0073] In the embodiments of this application, the apparatus for implementing the function of the network device can be a network device; or can be an apparatus capable of supporting the network device to implement the function, such as a chip system. The apparatus can be installed in the network device or used in matching with the network device. For ease of description, the apparatus for implementing the function of the network device is taken as a base station to describe the technical solutions provided in the embodiments of this application when some specific examples are involved.

[0074] With the development of 5G technology, the capability requirements of 5G networks on terminals are getting higher and higher. In typical services (such as comprehensive web browsing, instant messaging, gaming, video, etc.), the power consumption of 5G terminal communication is much higher than that of 4th generation (4G) terminal communication. The terminal's persistent endurance capability is an important aspect of user experience, which will affect the use of 5G terminals or services. Therefore, the 5G terminal's persistent endurance capability is facing great challenges, and research on how to save 5G terminal power consumption is the key to solving the problem.

[0075] In order to save the power consumption of the terminal, an embodiment of the present application provides a wake-up method, as shown in FIG. 4, which includes steps 401-403. The method shown in FIG. 4 corresponds to the execution subject of the first terminal and the network device, or the execution subject of the method shown in FIG. 4 can be a chip in the first terminal and the network device. FIG. 4 takes the first terminal and the network device as an example for description. The execution subject of the wake-up method is not limited in the embodiments of the present application. The first terminal can be a terminal in the communication system shown in FIG. 1 and FIG. 2, and the network device can be a network device in the communication system shown in FIG. 1, or a super base station or a ground base station in the communication system shown in FIG. 2. Wherein:

[0076] 401. The network device sends a first wake-up signal, and the first wake-up signal carries the identification of a first subgroup.

[0077] Correspondingly, the first terminal receives the first wake-up signal.

[0078] In order to wake up the target terminal more accurately from the plurality of terminals, the network device divides the plurality of terminals to obtain a plurality of subgroups, each terminal in the plurality of terminals belongs to a subgroup, and any two subgroups in the plurality of subgroups include different terminals. It can be understood that the first wake-up signal carries the identification of the first subgroup, indicating that the target terminal needed to be woken up by the network device belongs to the first subgroup. The terminal not belonging to the first subgroup can determine that it is not the target terminal needed to be woken up by the network device according to the identification of the first subgroup after receiving the first wake-up signal, and can continue to be in the sleep state.

[0079] Wherein, the terminal can save power consumption through the sleep state, and the sleep state can also be called sleep mode, sleep state, sleep mode, energy-saving state, or energy-saving mode. The sleep state is mainly described in the embodiments of the present application. The terminal in the sleep state will no longer perform one or more of the following operations: data transmission, synchronization signal / physical broadcast channel block (SSB) detection, system message acquisition, or paging message monitoring.

[0080] The terminal in the sleep state can detect a wake-up signal. After the terminal receives the wake-up signal and determines that it is the target terminal needed to be woken up by the network device, the terminal can switch from the sleep state to the wake-up state. The wake-up state refers to the state of the terminal after being woken up from the sleep state, wherein the wake-up state can also be called wake-up mode, active state, active mode, normal state, or normal mode. The terminal in the wake-up state will perform one or more of the following operations: data transmission, SSB detection, system message acquisition, or paging message monitoring.

[0081] In some examples, the first wake-up signal is a low power wake-up signal (LP-WUS). Further, the terminal being in the sleep state means that a main radio (MR) of the terminal is in the sleep state or is powered off, and a low-power radio (LR) of the terminal is turned on. The MR can be referred to as a main receiver, a main communication module, a main circuit, or the like, and can be used to receive or send signaling, data, measurement signals, and the like. The low-power radio (LP-R module) can also be referred to as a low-power radio, a wake-up receiver (WUR), a low power WUR (LP-WUR), a wake-up circuit, an auxiliary communication module, an auxiliary circuit, or the like. The LR has a much lower power consumption than the MR. The LR is used to receive or send low-power signals (such as a low-power wake-up signal, a low-power synchronization signal, a low-power measurement signal, or the like), notify the MR of wake-up or sleep, and the like.

[0082] 402. The network device sends a second wake-up signal, and the second wake-up signal carries a first identifier of a target terminal that needs to be woken up.

[0083] Correspondingly, if the first terminal belongs to the first group, the first terminal receives the second wake-up signal. It can be understood that the first terminal can compare the identifier of the group to which the first terminal belongs with the identifier of the first group carried by the first wake-up signal to determine whether the first terminal belongs to the first group. If the identifier of the group to which the first terminal belongs is the same as the identifier of the first group, it can be considered that the first terminal belongs to the first group.

[0084] If the first terminal does not belong to the first group, the first terminal will continue to be in the sleep state and will not receive the second wake-up signal corresponding to the first wake-up signal. It can be understood that the first wake-up signal carries the identifier of the first group, indicating that the target terminal that needs to be woken up by the network device belongs to the first group. It can be understood that the first terminal can compare the identifier of the group to which the first terminal belongs with the identifier of the first group carried by the first wake-up signal to determine whether the first terminal belongs to the first group. If the identifier of the group to which the first terminal belongs is not the same as the identifier of the first group, it can be considered that the first terminal does not belong to the first group. The first terminal can determine that it is not the target terminal that needs to be woken up by the network device, and therefore, the first terminal can continue to be in the sleep state, thereby reducing power consumption.

[0085] In the embodiments of the present application, in order to avoid waking up non-target terminals in the first group, the second wake-up signal carries the first identifier of the target terminal in the first group that needs to be woken up. In the case that the first terminal belongs to the first group, the first terminal receives the second wake-up signal, and then can determine whether it is the target terminal that needs to be woken up by the network device in the first group according to the second wake-up signal. If the second wake-up signal does not carry the first identifier of the first terminal, the first terminal can continue to remain in the sleep state, thereby saving power consumption. Therefore, by the combination of the first wake-up signal and the second wake-up signal, the network device can more accurately wake up the target terminal, avoid waking up the non-target terminal for blind detection, waste the power consumption of the non-target terminal, thereby being beneficial to saving the power consumption of the terminal.

[0086] The first identifier can also be understood as a subgroup terminal identifier (subgroup-ue-index), that is, the first identifier is used to identify a terminal in a group, and the first identifiers of any two terminals in the same group are different, that is, in a group, one first identifier is used to identify one terminal.

[0087] In some examples, the one first identifier can be commonly used by the multiple groups, that is, two terminals belonging to different groups can use the same first identifier. Since the group identifier carried by the first wake-up signal can be used to distinguish different groups, such a way will not affect the accuracy of the network device waking up the terminal, and is also beneficial to making the second wake-up signal carry fewer information bits.

[0088] For example, as shown in FIG. 5, group 1 includes 3 terminals (terminal 1, terminal 2 and terminal 3), group 2 includes 3 terminals (terminal 4, terminal 5 and terminal 6), and group 3 includes 3 terminals (terminal 1, terminal 2 and terminal 3). The first identifiers of terminal 1, terminal 4 and terminal 7 are all 1, the first identifiers of terminal 2, terminal 5 and terminal 8 are all 2, and the first identifiers of terminal 3, terminal 6 and terminal 9 are all 3. If the first wake-up signal sent by the network device carries the identifier of group 2, and the first identifier carried in the second wake-up signal is 2, it can be determined that the target terminal woken up by the network device is terminal 5. If the first wake-up signal sent by the network device carries the identifier of group 1, and the first identifier carried in the second wake-up signal is 3, it can be determined that the target terminal woken up by the network device is terminal 3.

[0089] In some examples, the first identifier of the terminal is related to one or more of the following parameters: a terminal identifier (ue_id) of the terminal, a signal measurement value of the terminal, an area where the terminal is located, or a frequency point of the terminal.

[0090] For example, the first identifier of the terminal is calculated, for example, the first identifier of the terminal is determined according to the ue_id of the terminal. Wherein, the terminal and the network device calculate the same method, the terminal can calculate the first identifier according to its own ue_id, when the network device wakes up the target terminal through the second wake-up signal, the terminal can compare the first identifier carried in the second wake-up signal, so as to judge whether it is the target terminal which the network device needs to wake up.

[0091] For another example, the network device can sort a plurality of terminals according to the parameter, for example, the plurality of terminals can be sorted in descending order or ascending order according to the size of the parameter. Then, the network device can determine the first identifier of each terminal in the plurality of terminals according to the order, and inform the corresponding first identifier of each terminal in the plurality of terminals by sending indication information. For example, the network device can send third indication information to the first terminal, and the corresponding first terminal receives the third indication information, which indicates the identifier of the first terminal.

[0092] Optionally, the parameter can be one or more of the following: the area where the terminal is located, the frequency point of the terminal, or the signal measurement value of the terminal. Wherein, the area where the terminal is located refers to the location of the terminal, for example, it can be a location coordinate, and the network device can determine the area where the terminal is located according to one or more of the following: radio frequency map (Rfmap), satellite map, positioning algorithm, etc. The signal measurement value of the terminal can also be understood as signal strength information, for example, the signal measurement value can be reference signal received power (RSRP) or reference signal received quality (RSRQ), and the terminal can obtain the signal measurement value by measuring the reference signal sent by the network device, which can be channel state information reference signal (CSI-RS), demodulation reference signal (DMRS), sounding reference signal (SRS), phase tracking reference signal (PTRS), or positioning reference signal (PRS), etc. The frequency point of the terminal refers to the frequency point allocated by the network device to the terminal, and the terminal transmits signals on the frequency point.

[0093] Optionally, the third indication information can indicate the first identifier through a predefined bitmap. For example, the third indication information is M-bit information, the i-th bit of the M-bit information corresponds to the first identifier i, and i is an integer between 1 and M (inclusive). Among them, only one bit of the M-bit information has a first value, and the first identifier corresponding to the bit with the first value is the first identifier of the first terminal. The first value can be 1 or 0. For example, M = 4, the 4-bit information is 0010, and the bit with the value 1 corresponds to the first identifier of the first terminal. The third bit of the 4-bit information has a value of 1, so the first identifier of the first terminal is 3.

[0094] Optionally, the third indication information can be carried in radio resource control (RRC) configuration information.

[0095] In some examples, the second wake-up signal is an LP-WUS. In combination with the above description that the first wake-up signal is an LP-WUS, the first wake-up signal and the second wake-up signal can be different types of wake-up signals, i.e., the contents carried by the first wake-up signal and the second wake-up signal are different. After the first terminal receives the first wake-up signal and the second wake-up signal through the LR, the first terminal determines that the first terminal is the target terminal that needs to be woken up by the network device according to the identifier of the first group carried by the first wake-up signal and the first identifier of the target terminal carried by the second wake-up signal, and then triggers the main MR wake-up or startup. If it is determined that the first terminal is not the target terminal that needs to be woken up by the network device, the LR will not trigger the MR wake-up or startup, but continue to monitor the wake-up signal.

[0096] In some examples, the first wake-up signal and the second wake-up signal are two-level wake-up signals. The first wake-up signal can be a first-level wake-up signal, and the second wake-up signal is a second-level wake-up signal; or the second wake-up signal is a first-level wake-up signal, and the first wake-up signal is a second-level wake-up signal.

[0097] In some examples, before the first terminal receives the second wake-up signal, the method further includes: the network device sending first configuration information to the first terminal, and correspondingly, the first terminal receiving the first configuration information from the network device, wherein the first configuration information includes configuration information of the second wake-up signal. The configuration information of the second wake-up signal includes one or more of the following: the time domain resource position of the second wake-up signal, the frequency domain resource position where the second wake-up signal is located, or the number of information bits carried by the second wake-up signal. The number of information bits carried by the second wake-up signal refers to the payload size of the second wake-up signal.

[0098] Exemplarily, the first configuration information can indicate the time domain resource where the second wake-up signal is located in the following two ways:

[0099] (1) The first configuration information can directly indicate the time domain resource position where the second wake-up signal is located, for example, the first configuration information can indicate one or more of the following: the system frame number (SFN) where the second wake-up signal is located, the slot ID where the second wake-up signal is located, the symbol index where the second wake-up signal is located, or the number of symbols occupied by the second wake-up signal.

[0100] (2) The first configuration information can indicate the time interval between the first wake-up signal and the second wake-up signal. As shown in FIG. 6, after receiving the first wake-up signal, the first terminal can determine the time domain resource where the second wake-up signal associated with the first wake-up signal is located according to the time where the first wake-up signal is located and the time interval indicated by the first configuration information.

[0101] Exemplarily, the way in which the first configuration information indicates the frequency domain resource position where the second wake-up signal is located can be by indicating one or more of the following parameters: the index of the physical resource block (PRB) where the second wake-up signal is located, the resource element (RE) index where the second wake-up signal is located, or the frequency band length occupied by the second wake-up signal.

[0102] Optionally, the first configuration information can be RRC configuration information, system information, or high layer signaling.

[0103] In some other examples, the first wake-up signal carries the configuration information of the second wake-up signal, where the definition of the configuration information of the second wake-up signal is the same as described in the above examples and will not be repeated here. In this case, the terminal needs to receive the first wake-up signal before determining the configuration of the second wake-up signal. This way can make the configuration of the second wake-up signal by the network device more flexible.

[0104] In a possible implementation, since the target terminal is in a sleep state, the network device does not determine the actual position of the target terminal that needs to be woken up, and therefore needs to find the target terminal within the coverage of the network device by means of beam sweeping.

[0105] Example 1: The network device can send the first wake-up signal and the second wake-up signal through multiple beams. Wherein, the beam sweeping mode of the network device can be one of the following two patterns:

[0106] (1) The network device transmits the first wake-up signal through the multiple beams in a first time period, and transmits the second wake-up signal through the multiple beams in a second time period, where the first time period is before the second time period. It can be understood that the network device first transmits the first wake-up signal through the multiple beams, and then transmits the second wake-up signal through the multiple beams.

[0107] For example, as shown in FIG. 7A, the network device can use 4 beams to transmit signals, which are beam 1, beam 2, beam 3 and beam 4 respectively. The network device first transmits the first wake-up signal through the 4 beams in turn, and then transmits the second wake-up signal through the 4 beams in turn. The network device transmits the first wake-up signal through any beam before transmitting the second wake-up signal.

[0108] (2) The network device transmits the first wake-up signal and the second wake-up signal through the multiple beams in turn based on the ordering of the multiple beams. It can be understood that the network device first transmits the first wake-up signal and the second wake-up signal through a beam according to the ordering of the multiple beams, and then transmits the first wake-up signal and the second wake-up signal through the next beam according to the ordering. Taking beam 1 and beam 2 included in the multiple beams as an example, assuming that the ordering of beam 1 is before that of beam 2, the network device transmits the first wake-up signal and the second wake-up signal through beam 1 before transmitting the first wake-up signal and the second wake-up signal through beam 2. Optionally, the ordering of the multiple beams is related to the identification of the multiple beams, for example, the multiple beams can be arranged in order from small to large or from large to small according to the identification of the multiple beams. Optionally, when the network device transmits the first wake-up signal and the second wake-up signal through the same beam, the network device transmits the first wake-up signal through the beam before transmitting the second wake-up signal through the beam.

[0109] For example, as shown in FIG. 7B, the network device can use 4 beams to transmit signals, which are beam 1, beam 2, beam 3 and beam 4 respectively. The network device first transmits the first wake-up signal and the second wake-up signal through beam 1, then transmits the first wake-up signal and the second wake-up signal through beam 2, then transmits the first wake-up signal and the second wake-up signal through beam 3, and finally transmits the first wake-up signal and the second wake-up signal through beam 4.

[0110] Optionally, in combination with the above two modes, the network device can send third indication information to the first terminal, and the first terminal receives the third indication information, and the third indication information indicates the mode of beam sweeping of the network device, so that the first terminal determines which mode the network device uses to send the first wake-up signal and the second wake-up signal, and receives the first wake-up signal and the second wake-up signal based on the mode of beam sweeping of the network device. Further optionally, the third indication information is carried in RRC configuration information.

[0111] In example one, the first terminal can detect the first wake-up signal in the first detection window, and detect the second wake-up signal in the second detection window.

[0112] Optionally, the first terminal can perform signal measurement on the first wake-up signal sent by the network device through multiple beams, determine a first beam in the multiple beams, the first beam being the beam with the strongest signal strength in the multiple beams, and the first terminal receives the second wake-up signal from the network device at a position corresponding to the first beam. In combination with the above description, the first terminal detects the second wake-up signal in the second detection window, i.e. the position corresponding to the first beam is located in the second detection window. It can be understood that although the network device still sends the second wake-up signal through multiple beams, the first terminal has determined that the signal strength of the first beam is the highest, so the first terminal can not need to detect the second wake-up signal sent by the network device through beams other than the first beam, and therefore the second detection window can be set to be smaller than the first detection window, which is beneficial to saving the power consumption of the first terminal.

[0113] For example, as shown in FIG. 8, the network device can use four beams to send signals, and the four beams are beam 1, beam 2, beam 3 and beam 4. The network device first uses the four beams to send the first wake-up signal, and the first terminal performs signal measurement in the first detection window to obtain a signal measurement result, which includes the signal strengths corresponding to the four beams sending the first wake-up signal respectively. Through the signal measurement result, it is determined that the beam with the strongest signal strength in the four beams is beam 2, and then the second terminal can detect the second wake-up signal in the second detection window corresponding to beam 2.

[0114] In Example II, the network device can send the first wake-up signal through multiple beams, the first terminal can perform signal measurement on the first wake-up signal sent by the network device through multiple beams, determine a first beam in the multiple beams, the first beam being the beam with the strongest signal strength in the multiple beams, the first terminal sends first indication information to the network device, the first indication information indicating the first beam, the network device sends the second wake-up signal using the first beam, and correspondingly, the first terminal receives the second wake-up signal from the network device at a position corresponding to the first beam. In this example, the first terminal is taken as an example, and in actual scenarios, the terminals in the first group can all use the method described in Example II to inform the network device of the beam with the strongest signal strength measured by themselves through indication information, and then the network device can only use the beam with the strongest signal strength indicated by the terminal in the first group when sending the second wake-up signal. In this way, the network device can not need to use all beams to send the second wake-up signal, but only use part of the beams to send the second wake-up signal, which is conducive to reducing the power consumption of the network device.

[0115] For example, as shown in FIG. 9, the network device can use four beams to send signals, the four beams being beam 1, beam 2, beam 3, and beam 4. The network device first uses the four beams to send the first wake-up signal, and correspondingly, the first terminal performs signal measurement in the first detection window to obtain a signal measurement result, the signal measurement result including the signal strengths corresponding to the first wake-up signal sent by the four beams respectively. It is determined from the signal measurement result that the beam with the strongest signal strength in the four beams is beam 2. The first terminal sends first indication information, the first indication information indicating the first beam, and the network device sends the second wake-up signal using the first beam.

[0116] In some examples, the second wake-up signal can be a periodic signal, an aperiodic signal, or a semi-persistent signal. The types of the second wake-up signal are introduced as follows:

[0117] (1) The second wake-up signal is a periodic signal. That is, the second wake-up signal needs to be sent periodically, and the time interval between two second wake-up signals sent by the network device in succession is fixed, being a period.

[0118] Optionally, the first wake-up signal is a periodic signal, and a period of the first wake-up signal is less than or equal to a period of the second wake-up signal. In this way, the network device does not need to send the second wake-up signal each time after sending the first wake-up signal. For example, in some scenarios, the network device can only send the first wake-up signal without sending the second wake-up signal. For example, when the network device needs to wake up all the first terminals in a group, the network device only needs to send the first wake-up signal. Therefore, in general, the network device sends the first wake-up signal more frequently than the second wake-up signal. By setting the period of the first wake-up signal to be less than or equal to the period of the second wake-up signal, the network device can send more first wake-up signals.

[0119] As shown in FIG. 10, the period of the first wake-up signal refers to the interval between the start time or the end time of two consecutive time domain resources for sending the first wake-up signal, and the period of the second wake-up signal refers to the interval between the start time or the end time of two consecutive time domain resources for sending the second wake-up signal. In time period 1, the first wake-up signal is sent 3 times, and the second wake-up signal is sent 2 times. In this way, the network device can send the second wake-up signal less frequently than the first wake-up signal.

[0120] Optionally, the network device can send fourth indication information to the first terminal, where the fourth indication information is used to indicate the period of the first wake-up signal and / or the second wake-up signal. Further optionally, the fourth indication information is carried in RRC configuration information or high-layer signaling.

[0121] (2) The second wake-up signal is a non-periodic signal. That is, the network device does not need to send the second wake-up signal periodically, but can send the second wake-up signal flexibly when needed.

[0122] Optionally, the network device sends fifth indication information before sending the second wake-up signal, where the fifth indication information indicates the resource for sending the second wake-up signal. Further optionally, the fifth indication information can be carried in high-layer signaling or the first wake-up signal.

[0123] (3) The second wake-up signal is a semi-static signal. That is, the second wake-up signal needs to be activated or triggered by activation information. That is, the network device can send the activation information, and after sending the activation information, the network device will send the second wake-up signal periodically.

[0124] Exemplarily, the second indication information carries activation information for activating the second wake-up signal, i.e., the second wake-up signal can be activated or triggered by the second indication information. The implementation manner is that: before the network device sends the second wake-up signal, the network device sends the second indication information, and correspondingly, the first terminal receives the second indication information, the second indication information indicates to activate the second wake-up signal, or the second indication information indicates that the network device sends the second wake-up signal in the first time window. Optionally, the second indication information is high-layer signaling.

[0125] When the second indication information indicates to activate the second wake-up signal, it means that the network device will send the second wake-up signal after sending the second indication information. Correspondingly, after the first terminal receives the second indication information, the first terminal detects the second wake-up signal.

[0126] When the second indication information indicates that the network device sends the second wake-up signal in the first time window, it means that the network device will send the second wake-up signal in the first time window. Correspondingly, as shown in FIG. 11, after the first terminal receives the second indication information, the first terminal can directly detect the second wake-up signal in the first time window.

[0127] Exemplarily, the first wake-up signal carries activation information for activating the second wake-up signal, i.e., the second wake-up signal can be activated or triggered by the first wake-up signal. It can be understood that the first wake-up signal is also used to indicate to activate the second wake-up signal, or the first wake-up signal indicates that the network device sends the second wake-up signal in the first time window.

[0128] Similarly, when the first wake-up signal indicates to activate the second wake-up signal, it means that the network device will send the second wake-up signal after sending the first wake-up signal indicating to activate the second wake-up signal. Correspondingly, after the first terminal receives the first wake-up signal indicating to activate the second wake-up signal, the first terminal detects the second wake-up signal.

[0129] When the first wake-up signal indicates that the network device sends the second wake-up signal in the first time window, it means that the network device will send the second wake-up signal in the first time window. Correspondingly, as shown in FIG. 11, after the first terminal receives the first wake-up signal, the first terminal detects the second wake-up signal in the first time window.

[0130] Optionally, when the second indication information or the first wake-up signal carries activation information for activating the second wake-up signal, the network device can also send deactivation information for deactivating the second wake-up signal, and after sending the deactivation information, the network device will no longer periodically send the second wake-up signal.

[0131] 403、if the first terminal belongs to the first group, receiving a second wake-up signal carrying a first identifier of a target terminal to be woken up; and

[0132] By carrying the group in which the target terminal is located through the first wake-up signal and carrying the first identifier of the target terminal through the second wake-up signal, the first terminal can directly determine whether it is the target terminal that needs to be woken up by the network device, and thus based on the method described in the application. The network device can more accurately wake up the target terminal, avoid waking up the non-target terminal for blind detection, waste the power consumption of the non-target terminal, thereby saving the power consumption of the terminal.
