Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a wake-up signal monitoring method and a communication device. Background Art

[0002] The low power wake up signal (LP-WUS), also known as the wake up signal (WUS), is used to trigger the opening of the main circuit to receive paging messages or initiate random access. Usually, the terminal device monitors WUS in two ways: continuous monitoring and discontinuous monitoring. The discontinuous monitoring method is also called duty-cycle monitoring. In the duty-cycle monitoring method, the terminal device determines the WUS monitoring occasion (MO) corresponding to the terminal device according to the configuration of the network device. How to configure the WUS MO corresponding to the terminal device has become an urgent problem to be solved. Summary of the invention

[0039] The terms "first" and "second" and the like in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It should be understood that the embodiments described herein may be combined with other embodiments.

[0041] In order to facilitate a specific understanding of the embodiments of the present application, the system architecture involved in the embodiments of the present application is first introduced below.

[0042] Figure 1a FIG. 1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1a As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as Figure 1a 110a and 110b in the figure, collectively referred to as 110), and may also include at least one terminal (such as Figure 1a RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1a The terminal 120 is connected to the RAN node 110 (hereinafter also referred to as the network device 110) by wireless means, and the RAN node 110 is connected to the core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be independent and different physical devices, or may be the same physical device that integrates the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals and RAN nodes and RAN nodes may be connected to each other by wired or wireless means.

[0043] RAN100 may be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, and a future radio access system defined in the 3rd generation partnership project (3GPP). RAN100 may also include two or more of the above-mentioned different radio access systems. RAN100 may also be an open RAN (O-RAN).

[0044] RAN nodes, also known as radio access network equipment, RAN entities or access nodes, are used to help terminals access the communication system wirelessly. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, a next generation NodeB in a sixth generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (such as a Figure 1a 110a), or a micro base station or an indoor station (such as Figure 1a 110b) in the figure, it can also be a relay node or a donor node.

[0045] In another application scenario, the cooperation of multiple RAN nodes can be used to help the terminal achieve wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU) or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of 3GPP. RU can be used to implement the transceiver function of radio frequency signals. CU and DU can be two independent RAN nodes, or they can be integrated in the same RAN node, such as integrated in a baseband unit (BBU). RU can be included in a radio frequency device, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0046] In different systems, RAN nodes may have different names. For example, in an O-RAN system, CU may be called an open CU (open CU, O-CU), DU may be called an open DU (open DU, O-DU), and RU may be called an open RU (open RU, O-RU). The RAN node in the embodiment of the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node may be a server loaded with a corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form adopted by the RAN node. For the convenience of description, the following description takes a base station as an example of a RAN node.

[0047] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be called a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0048] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0049] The roles of the base station and the terminal can be relative, for example, Figure 1a The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1a 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1a 120a-120j in the figure can be called communication devices with terminal functions.

[0050] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0051] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem including the base station function. The control subsystem including the base station function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or a modem) in the terminal, or by a device including the terminal function.

[0052] In order to facilitate understanding of the relevant contents of the embodiments of the present application, some of the terms involved in the embodiments of the present application are explained below. This part is only for ease of understanding and cannot be regarded as a disclosure or specific limitation of the technical solution of the present application.

[0053] 1. Warning information

[0054] The warning information mentioned in this application includes but is not limited to earthquake and tsunami warning system (ETWS) information and / or commercial mobile alert system (CMAS) information. In the new radio (NR) system, the network device can send warning information to the terminal device through a broadcast message. Usually, the warning information includes two parts: a primary notification message and a secondary notification message, and the priority of the primary notification message is higher than the priority of the secondary notification message. Among them:

[0055] The main notification message is used to indicate the urgent information in the warning information, and the data volume is relatively small. For example, the main notification message of ETWS includes the category of the message (used to indicate whether it is an earthquake warning or a tsunami warning) and the way the terminal device prompts the user. Usually, the network device needs to complete the main notification message from the operator to the terminal device within 4 seconds (that is, the transmission delay between the network device and the terminal device does not exceed 4 seconds), and the data volume of the main notification message is about a few bytes.

[0056] Auxiliary notification messages are used to indicate less urgent information in the warning information, and the data volume is large. For example, the auxiliary notification message of ETWS includes the purpose of the message (whether it is a warning information for testing or training, etc.), a safe place, how to get help, the time of food distribution, etc. For auxiliary notification messages, there are usually no clear requirements for transmission delay and data volume.

[0057] 2. Paging

[0058] Paging is a process in which a network device periodically sends a paging message to a terminal device in an idle state or an inactive state to return the terminal device from an idle state or an inactive state to a connected state. The process includes: the network device determines the paging occasion (PO) corresponding to the terminal device, and sends a physical downlink control channel (PDCCH) carrying paging downlink control information (DCI) to the terminal device on the PO. The paging DCI can schedule a physical downlink shared channel (PDSCH) carrying a paging message. If the paging DCI indicates that a PDSCH carrying a paging message is scheduled, the network device sends a PDSCH carrying a paging message at the resource location indicated by the paging DCI. Correspondingly, the terminal monitors the paging DCI on its corresponding PO. If the terminal receives the paging DCI, it receives the PDSCH carrying the paging message according to the received paging DCI, and determines whether it is paged according to the PDSCH carrying the paging message. For example, if the paging message received by the terminal carries its own identification information (such as user equipment identifier (UE ID)), it determines that it is paged; otherwise, it determines that it is not paged. If the terminal is paged, the terminal initiates a random access process, switches to the connected state, establishes a communication connection with the network device, and then communicates data with the network device.

[0059] Depending on the initiator of paging, paging can be divided into core network paging (CN paging) and access network paging (RAN paging).

[0060] Core network paging refers to paging initiated by the core network device and received by the terminal device when it is in an idle state. The core network device sends the identifier of the terminal device to be paged (e.g., system architecture evolution (SAE) temporary mobile subscriber identity (TMSI), also known as S-TMSI) to each base station in the tracking area where the terminal device is located, so that each base station in the tracking area where the terminal device is located sends a paging message to the terminal device. It should be noted that for the base station, the base station will broadcast the tracking area where the current base station is located in the system message, for example, through the TrackingAreaCode in the system information. For the terminal device, when the terminal device moves to a new cell in the idle state, it will receive the system information of the new cell, and the TrackingAreaCode in the system information can be used to determine whether it has moved to the new tracking area; if the terminal device determines that it has entered the new tracking area, the terminal device will initiate the tracking area update process to inform the network side of the tracking area where the terminal device is currently located, so that the core network device can initiate paging for the terminal device according to the tracking area where the terminal device is currently located.

[0061] Access network paging refers to paging initiated by a base station and received by a terminal device when it is in an inactive state. Specifically, when a terminal device changes from a connected state to an inactive state, the base station (called the last serving gNB) corresponding to the cell to which the terminal device is connected (called the last serving cell) sends the identifier of the terminal device to be paged (for example, an inactive radio network temporary identifier (I-RNTI)) to each base station in the radio access network area (RAN area) where the terminal device is located, so that each base station in the RAN area where the terminal device is located sends a paging message to the terminal device. The identifier of the terminal device is allocated by the last serving cell. It should be noted that, for base stations, the base station will broadcast the RAN area where the current base station is located in the system information, for example, by indicating it through the RAN-AreaCode in the system information. For terminal devices, when the terminal device moves to a new cell in the inactive state, it will receive the system information of the new cell. The RAN-AreaCode in the system information can be used to determine whether it has moved to the new RAN area. If the terminal device determines that it has entered the new RAN area, the terminal device will initiate the RAN area update process to inform the network side of the RAN area where the terminal device is currently located, so that the base station can initiate paging to the terminal device based on the RAN area where the terminal device is currently located.

[0062] 3. System information update

[0063] In NR, the system information of the cell is not updated frequently. After the terminal device reads the system information of the cell, the terminal device will not read the system information frequently. When the system information of the cell is updated, the terminal device needs to read the updated system information, otherwise errors may occur. For example, if the cell updates the configuration related to paging, if the terminal device does not read the updated system information, the terminal device cannot correctly receive the paging message. For another example, if the cell updates the configuration related to random access, if the terminal device does not read the updated system information, the terminal device cannot successfully initiate random access.

[0064] In order to ensure that the terminal device can read the system information in time after it is updated, the paging DCI usually includes 1 bit of system information change indication information (SI change) for indicating whether the terminal device needs to re-read the system information.

[0065] In one possible implementation, the SI change includes ETWS&CMAS indication information (or ETWS&CMAS flag). When the system information includes ETWS message and / or CMAS message, the terminal device can also be instructed to re-read the system information by including 1-bit ETWS&CMAS indication information in the paging DCI.

[0066] 4. Wake up receiver (WUR) link

[0067] In general, whether the terminal device is in an idle / inactive state to perform a paging receiving process, or the terminal device is in a connected state to receive data, the terminal device uses the same receiving module (or receiver, or receiving circuit). In the present application, the module that completes these functions (or performs related steps) may be referred to as the first module. It is understood that the first module is only named for distinction, and its specific naming does not limit the scope of protection of the present application. For example, the first module may also be a first circuit or a main circuit. For ease of description, the following description is uniformly referred to as the first module.

[0068] The process of receiving a signal using the first module of the terminal device can be referred to as the process of transmitting the signal on a link (which can be referred to as the first link for distinction). The first link represents a connection relationship between the terminal device and the network device, which is a logical concept rather than a physical entity. The first link can also be referred to as the main link. For the sake of convenience, it is uniformly described as the first link below.

[0069] It can be understood that the power consumption of the terminal device in executing the process of receiving paging through the first module is relatively high. For example, the terminal device first uses the receiving module of the first module to receive the downlink signal, then blindly detects the physical downlink control channel (PDCCH), and finally decodes the received physical downlink shared channel (PDSCH), etc., which will bring about greater power consumption. In addition, since the circuit structure of the first module is relatively complex, its baseline power consumption during operation will also be relatively high.

[0070] In order to reduce the high power consumption caused by the terminal device executing the process of receiving paging through the first module, the terminal device can use a separate low-power small circuit to receive a wake-up signal (wake up signal / radio, WUS / WUR). The wake-up signal is used to indicate paging-related information, and the paging-related information may include: the terminal device or terminal device group being paged. The above-mentioned low-power small circuit can be implemented using a separate small circuit or chip with a simple structure, so that the power consumption of the low-power small circuit can be lower.

[0071] In one possible implementation, the low-power small circuit can also be a wake-up receiver (WUR), or a wake-up circuit, or a low-power circuit, etc. Among them, this application does not limit the specific naming of the low-power small circuit. In this application, the low-power small circuit can be referred to as the second module. It can be understood that the second module is only named for distinction, and its specific naming does not limit the scope of protection of this application. For example, the second module can also be a second circuit or a wake-up circuit. For ease of explanation, the low-power small circuit is uniformly described as the second module below.

[0072] Similarly, the process of the terminal device using the second module to receive the signal can be called the process of the signal being transmitted on the link (for distinction, recorded as the second link). Among them, the second link represents a connection relationship between the terminal device and the network device, which is a logical concept rather than a physical entity. It should be understood that the wake-up signal is only an example name, and this application does not limit its naming. In addition, the description of the terminal device using the second module to receive the wake-up signal can be found in Figure 2 .

[0073] Figure 1b This is a schematic diagram of the operation of the second module in the terminal device provided in an embodiment of the present application.

[0074] like Figure 1b As shown, the terminal device includes a first module and a second module, wherein the second module can receive a wake-up signal, such as LP-WUS.

[0075] Exemplarily, the wake-up signal can carry paging information. When the terminal device is in an idle / inactive state, if the second module detects the wake-up signal, it can trigger the first module to put the first module into an on state. If the second module does not detect the wake-up signal, it can put the first module into an off state or an ultra-deepsleep state.

[0076] If the paging information carried by the wake-up signal can indicate the terminal device #1 being paged, the second module of the terminal device #1 can trigger the first module after detecting the paging information, so that the terminal device #1 initiates a random access process after the first module is in the turned-on state. If the paging information carried by the wake-up signal indicates the terminal device group to which the paged terminal device #1 belongs, the second module of the terminal device #1 can trigger the first module after detecting the paging information, so that the terminal device #1 receives paging on the PO after the first module is in the turned-on state, and determines whether it is paged according to the result of the paging. The terminal device can receive paging periodically. As an example, the terminal device can calculate a paging frame (PF) and the position of a PO in a PF according to its own identifier (ID) (or UE ID), and receive paging in the PO.

[0077] Exemplarily, the wake-up signal can carry PDCCH monitoring indication information. When the terminal device is in the connected state, if the second module detects the wake-up signal, it can trigger the first module to put the first module into the on state to monitor PDCCH. If the second module does not detect the wake-up signal, the first module can be put into a certain sleep state (for example, micro sleep, light sleep, or deep sleep).

[0078] It can be understood that the first module in the on state can detect or receive other signals except the wake-up signal, and the first module in the off state does not detect or receive any signal.

[0079] 5. Modulation method of LP-WUS

[0080] It should be noted that the modulation methods mentioned in the present application include but are not limited to on-off keying (OOK) modulation and frequency-shift keying (FSK) modulation.

[0081] 5.1OOK Modulation

[0082] When LP-WUS adopts OOK modulation, the WUR of the terminal device can receive LP-WUS by envelope detection. When LP-WUS adopts OOK modulation, each (encoded) bit corresponds to a symbol, which can also be called a chip. After receiving a signal in a symbol, the value of the bit corresponding to the symbol can be determined based on whether there is a signal in the symbol.

[0083] In one example, when a signal is sent within a certain symbol length (i.e., the signal power within the symbol length is not 0, or the signal within the symbol length is an ON signal), the bit corresponding to the symbol is "1". When no signal is sent within a certain symbol length (i.e., the signal power within the symbol length is 0, or the signal within the symbol length is an OFF signal), the bit corresponding to the symbol is "0". For example, the received signal waveform is as follows Figure 2 As shown, the waveform represents four bits "1010". In another example, the bit corresponding to the symbol in which a signal is sent within the symbol length (that is, the signal power within the symbol length is not 0) can also be determined as "0", and the bit corresponding to the symbol in which no signal is sent within the symbol length (that is, the signal power within the symbol length is 0) can be determined as "1". This application does not make specific limitations on this.

[0084] In a possible implementation, after the WUR receives the OOK modulated LP-WUS, the LP-WUS can be demodulated according to a threshold value. If the signal power (or signal amplitude) received by the WUR is higher than the threshold value within a symbol length, the value of the bit received by the WUR is considered to be 1; if the signal power (or signal amplitude) received by the WUR is lower than the threshold value, the value of the bit received by the WUR is considered to be 0.

[0085] In another possible implementation, LP-WUS can be a signal based on OOK modulation after Manchester encoding, that is, when the transmitter sends a signal, it uses 2 OOK symbols to send 1 bit of original information. For example, Manchester encoding will encode the original information bit "0" as "10" and the original information bit "1" as "01", so that the original information bit "0" corresponds to an ON signal followed by an OFF signal, and the original information bit "1" corresponds to an OFF signal followed by an ON signal. Furthermore, after the WUR receives the LP-WUS modulated by OOK after Manchester encoding, it can compare the relative size of the signal power (or signal amplitude) in two adjacent symbols; if the signal power (or signal amplitude) in the previous symbol is greater than the signal power (or signal amplitude) in the subsequent symbol, the received bit is considered to be "0", otherwise the received bit is considered to be "1".

[0086] 5.2FSK modulation

[0087] When FSK modulation is adopted in LP-WUS, different information can use different frequency resources. For example, 2FSK carries 1 bit of information through 2 frequency resources (i.e., frequency resource f0 and frequency resource f1); when the value of the bit of the original information is 0, the information can be sent on frequency resource f0, and no information is sent on frequency resource f1; when the value of the bit of the original information is 1, the information can be sent on frequency resource f1, and no information is sent on frequency resource f0. Assuming f0 < f1, the FSK signal waveform of the information 0101 is as Figure 3 shown. The frequency of the signal is lower within the first and third symbols, and the frequency of the signal is higher within the second and fourth symbols.

[0088] In a possible implementation, FSK can also support higher modulation orders to carry more information. For example, 4FSK can carry 2 bits of information through 4 candidate frequency domain resources (i.e., frequency resources f0 to f3); when the original information bits are 00, the information can be sent on frequency resource f0, and no information is sent on frequency resources f1, f2, and f3; when the original information bits are 01, the information can be sent on frequency resource f1, and no information is sent on frequency resources f0, f2, and f3; when the original information bits are 10, the information can be sent on frequency resource f2, and no information is sent on frequency resources f0, f1, and f3; when the original information bits are 11, the information can be sent on frequency resource f3, and no information is sent on frequency resources f0, f1, and f2. Thus, the receiving end can compare the power levels on multiple frequency resources to determine the transmitted information.

[0089] The above "frequency resource" can also be equivalently referred to as "frequency position".

[0090] 6. Monitoring methods for LP-WUS

[0091] The monitoring methods by which the terminal device monitors LP-WUS include but are not limited to the following two monitoring methods: continuous monitoring and duty-cycle monitoring. Among them, continuous monitoring means that the WUR for the terminal device to receive LP-WUS is always on, and LP-WUS is monitored at all possible transmission opportunities (or understood as positions) of LP-WUS. Duty-cycle monitoring can also be referred to as discontinuous monitoring or periodic monitoring, which means that the WUR for the terminal device to receive LP-WUS is intermittently turned on (i.e., turned on for some time or turned off for some time), and LP-WUS is monitored only at some possible transmission opportunities of LP-WUS.

[0092] Exemplarily, the monitoring opportunities configured by the network device for terminal devices 1 to 4 are as Figure 4As shown in 4a in FIG. 4 , for the terminal device 1, if the terminal device 1 monitors the LP-WUS in a continuous monitoring manner, the terminal device is as follows Figure 4 As shown in 4b in FIG. 4 , LP-WUS will be monitored at all possible monitoring opportunities; if the terminal device 1 monitors LP-WUS by monitoring the duty cycle, the terminal device Figure 4 As shown in 4c in FIG, LP-WUS is monitored at some possible monitoring opportunities.

[0093] When the terminal device adopts the duty cycle monitoring mode, in order to improve the flexibility of the terminal device to monitor LP-WUS, the present application provides a wake-up signal monitoring method. The wake-up signal monitoring method and the communication device provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. Figure 5 FIG. 1 is a flow chart of a wake-up signal monitoring method provided in an embodiment of the present application. Figure 5 As shown, the wake-up signal monitoring method includes the following steps S501 to S502: Figure 5 The method execution subject shown is described by taking a terminal device and a network device as an example. It can be understood that Figure 5 The execution subject of the method shown may also be a device in a terminal device and a device in a network device, or a device used in conjunction with a terminal device and a device used in conjunction with a network device, for example, a chip (system) in a terminal device and a chip (system) in a network device. The processing performed by a single execution subject shown in the embodiments of the present application may also be divided into executions by multiple execution subjects, which may be logically and / or physically separated, for example, the processing performed by a network device may be divided into executions by one or more of a CU, a DU, and a RU.

[0094] in:

[0095] S501, a terminal device receives first configuration information of LP-WUS, where the first configuration information is used to configure a first MO set and a second MO set. Correspondingly, a network device sends the first configuration information of LP-WUS.

[0096] Among them, the first configuration information is used to configure one or more of the first monitoring period, the first monitoring offset value and the first monitoring duration corresponding to the first MO set; the first configuration information is also used to configure one or more of the second monitoring period, the second monitoring offset value and the second monitoring duration corresponding to the second MO set. It should be noted that the MO set mentioned in this application (including the first MO set and the second MO set) includes multiple MOs, which is a set of periodically appearing MOs. It can also be understood that the first MO set includes multiple first MOs, and the interval between the start times of two adjacent first MOs is the first monitoring period of the first MO set; the second MO set includes multiple second MOs, and the interval between the start times of two adjacent second MOs is the second monitoring period of the second MO set. In this application, the first MO set can also be equivalently understood as the first MO, at which time the first MO is a class of MO, and the first MO appears once and can be called an instance of the first MO, and the interval between the start times of two adjacent instances of the first MO is the first monitoring period of the first MO, and the second MO set can also be equivalently understood as the second MO, at which time the second MO is also a class of MO, and the second MO appears once and can be called an instance of the second MO, and the interval between the start times of two adjacent instances of the second MO is the second monitoring period of the second MO.

[0097] The network device sends the first configuration information of LP-WUS to multiple terminal devices, and each terminal device determines a common first MO set and a second MO set corresponding to the terminal device according to the first configuration information. It can be understood that different terminal devices (or terminal devices of different terminal device groups) can determine a same MO set (i.e., the first MO set) and different MO sets (i.e., the second MO set) according to the first configuration information. The first MO set is a common MO set corresponding to all terminal devices, that is, all terminal devices can monitor LP-WUS according to the first MO set; and the second MO set is a unique MO set corresponding to different terminal devices (or terminal devices of different terminal device groups), and each (or each group) of terminal devices monitors LP-WUS according to its corresponding second MO set.

[0098] For example, terminal device 1 is a terminal device in device group 1, and terminal device 2 is a terminal device in device group 2. Figure 6 As shown, terminal device 1 determines MO set 1 (i.e., the first MO set, consisting of multiple MO 1s) and MO set 2 (i.e., the second MO set corresponding to terminal device 1, consisting of multiple MO 2s) based on the first configuration information. Terminal device 2 determines MO set 1 (i.e., the first MO set, consisting of multiple MO 1s) and MO set 3 (i.e., the second MO set corresponding to terminal device 2, consisting of multiple MO 3s) based on the first configuration information.

[0099] In a possible implementation, the aforementioned first configuration information is used to configure the second monitoring period and / or the second monitoring duration, that is, when the first configuration information does not configure the second monitoring offset value of the second MO set, the terminal device and the network device can determine the second monitoring offset value corresponding to the terminal device based on the identification of the terminal device.

[0100] Exemplarily, the network device configures a common first MO set and N second MO sets for N terminal devices (or N terminal device groups) respectively through first configuration information, and the first configuration information does not include the second monitoring offset values ​​corresponding to each second MO set. In this case, the network device and the terminal device can determine the second monitoring offset value corresponding to each terminal device according to Formula 1.

[0101] Second monitoring offset value = ID%(N+1)(1) of terminal device

[0102] In a possible implementation, the first configuration information may configure the first monitoring period and the second monitoring period through the same period configuration parameter, for example, the first configuration information includes a first period configuration parameter, and the first period configuration parameter is used to configure the first monitoring period and the second monitoring period; in this case, the first monitoring period is the same as the second monitoring period. Alternatively, the first configuration information may also configure the first monitoring period and the second monitoring period through different period configuration parameters, for example, the first configuration information includes a second period configuration parameter and a third period configuration parameter, the second period configuration parameter is used to configure the first monitoring period, and the third period configuration parameter is used to configure the second monitoring period; in this case, the first monitoring period and the second monitoring period may be the same or different.

[0103] When the first monitoring period is the same as the second monitoring period, the second MO set does not overlap with the first MO set.

[0104] It is understandable that, when the network device configures N second MO sets and 1 first MO set for N terminal devices (or N terminal device groups), the MO sets do not overlap. That is, the first MO set does not overlap with any of the N second MO sets, and any two of the N second MO sets do not overlap. It should be noted that the non-overlap mentioned in this application includes completely non-overlapping or partially non-overlapping situations.

[0105] In a possible implementation, the first configuration information may configure the first monitoring duration and the second monitoring duration through the same duration configuration parameter, for example, the first configuration information includes a first duration configuration parameter, and the first duration configuration parameter is used to configure the first monitoring duration and the second monitoring duration; in this case, the first monitoring duration and the second monitoring duration are the same. Alternatively, the first configuration information may also configure the first monitoring duration and the second monitoring duration through different duration configuration parameters, for example, the first configuration information includes a second duration configuration parameter and a third duration configuration parameter, the second duration configuration parameter is used to configure the first monitoring duration, and the third duration configuration parameter is used to configure the second monitoring duration; in this case, the first monitoring duration and the second monitoring duration may be the same or different.

[0106] S502: The terminal device monitors the LP-WUS according to the first MO set and the second MO set. Correspondingly, the network device sends the LP-WUS according to the first MO set and the second MO set.

[0107] It can be understood that the network device configures N second MO sets and one first MO set for N terminal devices. For any terminal device, the network device sends LP-WUS to the terminal device according to the second MO set and the first MO set corresponding to the terminal device, and the terminal device also monitors LP-WUS in its corresponding second MO set and the first MO set.

[0108] Exemplarily, the network device configures MO set 1 (i.e., the first MO set) and MO set 2 (i.e., the second MO set corresponding to terminal device 1) for terminal device 1, and the network device configures MO set 1 (i.e., the first MO set) and MO set 3 (i.e., the second MO set corresponding to terminal device 2) for terminal device 2. In this case, the network device can send LP-WUS to terminal device 1 according to MO set 1 and MO set 2, and can send LP-WUS to terminal device 2 through MO set 1 and MO set 3.

[0109] In a possible implementation, the LP-WUS monitored by the terminal device according to the second MO set includes a second LP-WUS, and the second LP-WUS indicates wake-up information, and the wake-up information is used to wake up the terminal device. Correspondingly, the LP-WUS sent by the network device according to the second MO set includes the second LP-WUS. It can be understood that the network device can send a second LP-WUS on the second MO corresponding to the terminal device to wake up a terminal device when it is necessary to wake up the terminal device (for example, when a service arrives at the terminal device), wherein the second LP-WUS can include identification information related to the terminal device.

[0110] In a possible implementation, the LP-WUS monitored by the terminal device according to the first MO set includes a first LP-WUS, and the first LP-WUS indicates public information, which includes but is not limited to one or more of the following: SI change, ETWS identifier, CMAS identifier, cell information, tracking area information, wireless access network area information, ETWS information, CMAS information and second configuration information of the LP-WUS. Among them, the second configuration information of the LP-WUS is the configuration information for the terminal device to subsequently monitor the LP-WUS. For example, the terminal device receives the second configuration information of the LP-WUS in time slot n, and the second configuration information of the LP-WUS can be effective in time slot n+X, that is, starting from time slot n+X, the terminal device can monitor the LP-WUS according to the second configuration information, and before time slot n+X, the terminal device still monitors the LP-WUS according to the first configuration information.

[0111] In one possible implementation, in addition to monitoring the first LP-WUS according to the first MO set, the terminal device may also monitor a third LP-WUS according to the first MO set, and the third LP-WUS indicates wake-up information, and the wake-up information is used to wake up the terminal device. It can be understood that the third LP-WUS and the aforementioned second LP-WUS are of the same type of LP-WUS, which is an LP-WUS indicating wake-up information. In other words, for a certain terminal device, the network device may send an LP-WUS indicating wake-up information to the terminal device according to the second MO set corresponding to the terminal device, and may also send an LP-WUS indicating wake-up information to the terminal device according to the public first MO set. Through this possible implementation, when there is no LP-WUS indicating public information sent on the first MO set, the terminal device can be woken up according to the first MO set, which is beneficial to improving resource utilization.

[0112] It should be noted that the formats of the first LP-WUS, the second LP-WUS, and the third LP-WUS mentioned in this application may be the same or different, and this application does not specifically limit this. Among them, the formats of the two LP-WUS are different, which can be understood as the two LP-WUS carrying completely different information or not completely the same information.

[0113] In summary, through Figure 5 With the method shown, the terminal device can monitor LP-WUS according to multiple groups of MO sets, which is beneficial to improving the flexibility of the terminal device in monitoring LP-WUS compared to the method of monitoring LP-WUS according to only one group of MO sets.

[0114] It is understandable that in order to implement the functions in the above embodiments, the terminal device includes hardware structures and / or software modules corresponding to the execution of each function.

Whether a function is executed in the form of hardware or a computer software transceiver unit driving the hardware depends on the specific application scenario and design constraints of the technical solution.

[0127] like Figure 7 As shown, the communication device 700 includes a processing unit 710 and a transceiver unit 720. The communication device 700 is used to implement the above Figure 5 The functions of the network device in the method embodiment shown in FIG.

[0128] When the communication device 700 is used to implement Figure 5The functions of the network device in the method embodiment shown are: a transceiver unit 720, which is used to send first configuration information of a low power wake-up signal LP-WUS, and the first configuration information is used to configure a first listening opportunity MO set and a second MO set; the transceiver unit 720 is also used to send LP-WUS according to the first MO set and the second MO set.

[0137] For more detailed description of the transceiver unit 720 and the processing unit 710, please refer to Figure 5 The relevant description of the network device in the method embodiment is shown.

[0138] like Figure 8 As shown, the communication device 800 includes a processor 810 and an interface circuit 820. The processor 810 and the interface circuit 820 are coupled to each other. It is understood that the interface circuit 820 can be a transceiver or an input-output interface. Optionally, the communication device 800 may also include a memory 830 for storing instructions executed by the processor 810 or storing input data required by the processor 810 to execute instructions or storing data generated after the processor 810 executes instructions.

[0140] When the above-mentioned communication device is a chip applied to a terminal, the terminal chip implements the functions of the terminal in the above-mentioned method embodiment. The terminal chip receives information from the base station, which can be understood as the information is first received by other modules in the terminal (such as a radio frequency module or an antenna), and then sent to the terminal chip by these modules.
