Description

A wake-up signal monitoring method and communication device

[0001] This application claims priority to Chinese Patent Application No. 202310845224.1, filed on July 10, 2023, with the State Intellectual Property Office of China, entitled “A Wake-up Signal Monitoring Method and Communication Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and in particular to a wake-up signal monitoring method and communication device. Background Technology

[0003] The low-power wake-up signal (LP-WUS), also known as the wake-up signal (WUS), is used to trigger the main circuit to receive paging messages or initiate random access. Terminal devices typically monitor WUS using either continuous monitoring or discontinuous monitoring, with the latter also known as duty-cycle monitoring. In duty-cycle monitoring, the terminal device determines its corresponding WUS monitoring occasion (MO) based on the network device's configuration. Therefore, configuring the corresponding WUS MO for each terminal device is a crucial issue that needs to be addressed.

[0004] Summary of the Invention

[0005] This application provides a wake-up signal monitoring method and communication device, which helps to improve the flexibility of LP-WUS monitoring.

[0006] Firstly, this application provides a wake-up signal monitoring method. This method can be executed by a terminal device, by a device within the terminal device, or by a device compatible with the terminal device. For example, the method can be executed by a chip (system). Taking the execution of this method by a terminal device as an example, the method includes: the terminal device receiving first configuration information of a low-power wake-up signal LP-WUS, the first configuration information being used to configure a first listening time MO set and a second MO set; further, the terminal device monitoring LP-WUS according to the first MO set and the second MO set.

[0007] Based on the method described in the first aspect, the terminal device can monitor LP-WUS according to multiple sets of MOs, which is beneficial to improving the flexibility of the terminal device in monitoring LP-WUS compared to monitoring LP-WUS according to only one set of MOs.

[0008] In one possible implementation, the terminal device includes a second LP-WUS based on the LP-WUS monitored by the second MO set, the second LP-WUS indicating wake-up information used to wake up the terminal device.

[0009] In one possible implementation, the terminal device monitors the LP-WUS according to the first MO set, including a first LP-WUS indicating common information. This common information includes one or more of the following: System Information Change Indicator (SI change), Earthquake and Tsunami Warning System Information (ETWS) identifier, Commercial Mobile Warning System Information (CMAS) identifier, cell information, tracking area information, radio access network area, ETWS information, CMAS information, and second configuration information of the LP-WUS. Through this possible implementation, different terminal devices can receive common information based on the same first MO set, which helps reduce signaling overhead.

[0010] In one possible implementation, the terminal device, based on the LP-WUS monitored by the first MO set, also includes a third LP-WUS, which indicates wake-up information used to wake up the terminal device. Through this possible implementation, the terminal device can receive wake-up information in addition to public information on the first MO set, which helps avoid resource waste.

[0011] In one possible implementation, 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.

[0012] In one possible implementation, the first configuration information is used to configure the second monitoring period and / or the second monitoring duration. Further, the terminal device can determine the second monitoring offset value based on its identifier. By implementing this possible implementation, the first configuration information may not include the second monitoring offset value, which helps save transmission resources.

[0013] In one possible implementation, the first configuration information includes a first cycle configuration parameter used to configure a first monitoring cycle and a second monitoring cycle; alternatively, the first configuration information includes a second cycle configuration parameter and a third cycle configuration parameter, where the second cycle configuration parameter is used to configure the first monitoring cycle and the third cycle configuration parameter is used to configure the second monitoring cycle. By implementing this possible implementation, the first configuration information can configure the first and second monitoring cycles using the same configuration parameter, or it can configure the first and second monitoring cycles using different configuration parameters, which improves configuration flexibility.

[0014] In one possible implementation, the first monitoring period is the same as the second monitoring period, and the second MO set does not overlap with the first MO set.

[0015] In one possible implementation, the first configuration information includes a first duration configuration parameter, which is used to configure a first monitoring duration and a second monitoring duration; or, the first configuration information includes a second duration configuration parameter and a third duration configuration parameter, whereby 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. By implementing this possible implementation, the first configuration information can configure the first and second monitoring durations using the same configuration parameter, or it can configure the first and second monitoring durations using different configuration parameters, which helps to improve the flexibility of configuration.

[0016] Secondly, this application provides a wake-up signal monitoring method. This method can be executed by a network device, by a device within the network device, or by a device compatible with the network device. For example, the method can be executed by a chip (system). Taking the execution of this method by a network device as an example, the method includes: the network device sending first configuration information of a low-power wake-up signal LP-WUS, the first configuration information being used to configure a first listening time MO set and a second MO set; further, the network device sending LP-WUS according to the first MO set and the second MO set.

[0017] Based on the method described in the second aspect, network devices can send LP-WUS according to multiple sets of MOs, which improves the flexibility of network devices in sending LP-WUS compared to sending LP-WUS according to only one set of MOs.

[0018] In one possible implementation, the LP-WUS sent by the network device according to the second MO set includes a second LP-WUS indicating wake-up information for waking up the terminal device.

[0019] In one possible implementation, the LP-WUS transmitted by the network device according to the first MO set includes a first LP-WUS indicating common information, which includes one or more of the following: System Information Change Indicator (SI change), Earthquake and Tsunami Warning System Information (ETWS) identifier, Commercial Mobile Warning System Information (CMAS) identifier, cell information, tracking area information, radio access network area, ETWS information, CMAS information, and second configuration information of the LP-WUS. Through this possible implementation, the network device can configure the same first MO set to transmit common information to different terminal devices, which helps reduce signaling overhead.

[0020] In one possible implementation, the LP-WUS sent by the network device according to the first MO set also includes a third LP-WUS, which indicates wake-up information used to wake up the terminal device. Through this possible implementation, the network device can send wake-up information in addition to public information on the first MO set, which helps avoid wasting resources.

[0021] In one possible implementation, 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.

[0022] In one possible implementation, the first configuration information is used to configure the second monitoring period and / or the second monitoring duration, and the network device determines the second monitoring offset value based on the identifier of the terminal device. By implementing this possible implementation, the first configuration information may not include the second monitoring offset value, which helps to save transmission resources.

[0023] In one possible implementation, the first configuration information includes a first cycle configuration parameter, which is used to configure a first monitoring cycle and a second monitoring cycle; alternatively, the first configuration information includes a second cycle configuration parameter and a third cycle configuration parameter, where the second cycle configuration parameter is used to configure the first monitoring cycle, and the third cycle configuration parameter is used to configure the second monitoring cycle. By implementing this possible implementation, the first configuration information can configure the first and second monitoring cycles using the same configuration parameter, or it can configure the first and second monitoring cycles using different configuration parameters, which improves the flexibility of configuration.

[0024] In one possible implementation, the first monitoring period is the same as the second monitoring period, and the second MO set does not overlap with the first MO set.

[0025] In one possible implementation, the first configuration information includes a first duration configuration parameter, which is used to configure a first monitoring duration and a second monitoring duration; alternatively, the first configuration information includes a second duration configuration parameter and a third duration configuration parameter, whereby 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. By implementing this possible implementation, the first configuration information can configure the first and second monitoring durations using the same configuration parameter, or it can configure the first and second monitoring durations using different configuration parameters, which improves the flexibility of configuration.

[0041] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes 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 apparatuses.

[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. It should be understood that the embodiments described herein can be combined with other embodiments.

[0043] To facilitate a detailed understanding of the embodiments of this application, the system architecture involved in the embodiments of this application will be described below.

[0044] Figure 1a is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of this application. As shown in Figure 1a, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 1a, collectively referred to as 110), and may also include at least one terminal (120a-120j in Figure 1a, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1a). The terminal 120 is wirelessly connected to the RAN node 110 (hereinafter also referred to as network device 110), and the RAN node 110 is connected to the core network 200 wirelessly or via a wired connection. The core network equipment in core network 200 and the RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN node. Terminals can be interconnected with each other, and RAN nodes can be interconnected with each other, via wired or wireless means.

[0045] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, or a future radio access system as defined in the 3rd generation partnership project (3GPP). RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0046] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminals access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. RAN nodes can be macro base stations (such as 110a in Figure 1a), micro base stations or indoor stations (such as 110b in Figure 1a), relay nodes, or donor nodes.

[0047] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). The RU can be included in radio frequency equipment, such as in 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.

[0048] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes. For ease of description, a base station is used as an example of a RAN node in the following description.

[0049] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal.

[0050] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0051] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1a can be configured as a mobile base station. For terminals 120j that access the wireless access network 100 through 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1a can be called communication devices with base station functions, and 120a-120j in Figure 1a can be called communication devices with terminal functions.

[0052] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0053] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0054] To facilitate understanding of the relevant content of the embodiments of this application, some terms involved in the embodiments of this application will be explained below. This part is only for the purpose of understanding and should not be regarded as a disclosure or specific limitation of the technical solution of this application.

[0055] 1. Early warning information

[0056] The early 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 new radio (NR) systems, network devices can send early warning information to terminal devices via broadcast messages. Typically, early warning information consists of two parts: a primary notification message and a secondary notification message, with the primary notification message having a higher priority than the secondary notification message. Specifically:

[0057] The primary notification message is used to indicate urgent information in the warning information and has a relatively small data size. For example, the ETWS primary notification message includes the message category (indicating whether it is an earthquake warning or a tsunami warning) and the method by which the terminal device notifies the user. Typically, the network device needs to complete the process from receiving the primary notification message from the operator to transmitting it to the terminal device within 4 seconds (i.e., the transmission delay between the network device and the terminal device does not exceed 4 seconds), and the data size of this primary notification message is approximately a few bytes.

[0058] Supplementary notification messages are used to indicate less urgent information within the alert message and typically contain a larger amount of data. For example, ETWS supplementary notification messages include the purpose of the message (whether it is an alert message for testing or training purposes, etc.), safe location, how to get help, food distribution time, etc. For supplementary notification messages, there are usually no explicit requirements regarding transmission latency or data size.

[0059] 2. Paging

[0060] Paging is the process by which a network device periodically sends a paging message to a terminal device in an idle or inactive state, so that the terminal device can return from the idle or inactive state to the connected state. This process includes: the network device determining the paging occasion (PO) corresponding to the terminal device, and sending a physical downlink control channel (PDCCH) carrying paging downlink control information (DCI) to the terminal device on that PO. The paging DCI can schedule a physical downlink shared channel (PDSCH) carrying the paging message. If the paging DCI indicates that a PDSCH carrying the paging message has been scheduled, the network device sends the PDSCH carrying the 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 based on the received paging DCI. The terminal then determines whether it has been paged based on the PDSCH carrying the paging message. For example, if the paging message received by the terminal carries its own identification information (such as the user equipment identifier (UE ID)), it determines that it has been paged; otherwise, it determines that it has not been paged. If the terminal is paged, it initiates a random access procedure, switches to the connected state, establishes a communication connection with the network device, and then conducts data communication with the network device.

[0061] Depending on the initiator of the paging, paging can be divided into core network paging (CN paging) and access network paging (RAN paging). Among them:

[0062] Core network paging refers to a paging initiated by core network equipment and received by a terminal device in idle mode. The core network equipment sends the identifier of the paging terminal device (e.g., the System Architecture Evolution (SAE) Temporary Mobile Subscriber Identity (TMSI), also known as S-TMSI) to each base station within the terminal device's tracking area. This causes each base station within the tracking area to send a paging message to the terminal device. It should be noted that, for base stations, they broadcast their current tracking area in system messages, such as through the TrackingAreaCode in the system information. For the terminal device, when it moves to a new cell in idle mode, it receives the new cell's system information. The TrackingAreaCode in this system information determines whether it has moved to a new tracking area. If the terminal device determines it has entered a new tracking area, it initiates a tracking area update process, informing the network side of its current tracking area so that the core network equipment can initiate paging based on the terminal device's current tracking area.

[0063] Access network paging refers to a paging initiated by a base station and received by a terminal device when it is in an inactive state. Specifically, when a terminal device transitions from a connected state to an inactive state, the base station corresponding to the cell to which the terminal device is connected (called the last serving cell) (called the last serving gNB) sends the identifier of the paging terminal device (e.g., the inactive radio network temporary identifier (I-RNTI)) to all base stations within the radio access network area (RAN area) where the terminal device is located. This causes all base stations within the RAN area to send paging messages to the terminal device. The identifier of the terminal device is assigned by the last serving cell. It should be noted that, for the base station, the current RAN area it is located in is broadcast in the system information, for example, indicated by the RAN-AreaCode in the system information. For terminal devices, when a terminal device moves to a new cell in an 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 a new RAN area. If the terminal device determines that it has entered a new RAN area, it will initiate a 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 for the terminal device based on the RAN area where the terminal device is currently located.

[0064] 3. System information update

[0065] In NR (Non-Normalized Radio) systems, cell system information is not updated frequently. Even after a terminal device reads the cell's system information, it doesn't frequently reread it. However, when the cell's system information is updated, the terminal device needs to read the updated information; otherwise, errors may occur. For example, if the cell updates its paging-related configuration, the terminal device will not be able to correctly receive paging messages if it doesn't read the updated system information. Similarly, if the cell updates its random access-related configuration, the terminal device will not be able to successfully initiate random access if it doesn't read the updated system information.

[0066] To ensure that terminal devices can read system information in a timely manner after it is updated, the paging DCI usually includes a 1-bit system information change (SI change) indication, which indicates whether the terminal device needs to reread the system information.

[0067] In one possible implementation, the SI change includes ETWS&CMAS indication information (or ETWS&CMAS flag). When the system information contains ETWS messages and / or CMAS messages, the terminal device can also be instructed to reread the system information by including 1 bit of ETWS&CMAS indication information in the paging DCI.

[0068] 4. Wake-up receiver (WUR) link

[0069] Generally, regardless of whether the terminal device is in an idle / inactive state performing the paging process or in a connected state receiving data, the terminal device uses the same receiving module (or receiver, or receiving circuit). In this application, the module that performs these functions (or executes related steps) can be referred to as the first module. It is understood that the name "first module" is only for distinction, and its specific name does not limit the scope of protection of this application. For example, the first module can also be the first circuit or the main circuit. For ease of description, it will be uniformly referred to as the first module below.

[0070] The process by which the terminal device receives signals using the first module can be referred to as the process of signal transmission on the link (referred to as the first link for distinction). The first link represents a connection between the terminal device and the network device; it is a logical concept, not a physical entity. The first link can also be called the main link; for ease of explanation, it will be consistently referred to as the first link below.

[0071] It is understandable that the power consumption of the terminal device performing the paging reception process through the first module is relatively high. For example, the terminal device first uses the receiving module of the first module to receive downlink signals, then performs blind detection on the physical downlink control channel (PDCCH), and finally decodes the received physical downlink shared channel (PDSCH), all of which contribute to significant power consumption. Furthermore, due to the relatively complex circuit structure of the first module, its baseline power consumption during operation is also relatively high.

[0072] To reduce the high power consumption of the terminal device during the paging process in the first module, the terminal device can use a separate low-power circuit to receive the wake-up signal (WUS / WUR). The wake-up signal indicates paging-related information, which may include the paged terminal device or a group of terminal devices. This low-power circuit can be implemented using a simple, separate circuit or chip, thus resulting in low power consumption.

[0073] One possible implementation is that the low-power small circuit can also be a wake-up receiver (WUR), a wake-up circuit, or a low-power circuit, etc. This application does not limit the specific name of the low-power small circuit. In this application, the low-power small circuit can be referred to as a second module. It is understood that the name "second module" is only for distinction, and its specific name 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 will be uniformly described as a second module below.

[0074] Similarly, the process of the terminal device receiving signals using the second module can be referred to as the process of signal transmission on the link (referred to as the second link for distinction). Here, the second link represents a connection relationship between the terminal device and the network device; it is a logical concept, not a physical entity. It should be understood that "wake-up signal" is merely an example name, and this application does not limit its naming. Furthermore, a description of the terminal device receiving the wake-up signal using the second module can be found in Figure 2.

[0075] Figure 1b is a schematic diagram of the operation of the second module in the terminal device provided in the embodiment of this application.

[0076] As shown in Figure 1b, 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.

[0077] For example, 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 turn on. If the second module does not detect the wake-up signal, it can turn the first module off or into an ultra-deep sleep state.

[0078] If the paging information carried by the wake-up signal indicates the paged terminal device #1, then the second module of terminal device #1 can trigger the first module after detecting the paging information, enabling the first module and allowing terminal device #1 to initiate a random access procedure. If the paging information carried by the wake-up signal indicates the terminal device group to which the paged terminal device #1 belongs, then the second module of terminal device #1 can trigger the first module after detecting the paging information, enabling the first module and allowing terminal device #1 to receive paging on the PO, and determine whether it has been paged based on the paging result. Terminal devices can receive paging periodically. As an example, a terminal device can calculate a paging frame (PF) and the location of the PO within the PF based on its own identifier (ID) (or UE ID), and receive paging within the PO.

[0079] For example, 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 the PDCCH. If the second module does not detect the wake-up signal, it can put the first module into a certain sleep state (e.g., micro sleep, light sleep, or deep sleep).

[0080] It is understandable that the first module in the on state can detect or receive signals other than the wake-up signal, while the first module in the off state does not detect or receive signals.

[0081] 5. Modulation method for LP-WUS

[0082] It should be noted that the modulation methods mentioned in this application include, but are not limited to, on-off keying (OOK) modulation and frequency-shift keying (FSK) modulation.

[0083] 5.100K modulation

[0084] When LP-WUS uses OOK modulation, the WUR of the terminal device can receive LP-WUS using envelope detection. In LP-WUS using OOK modulation, each (encoded) bit corresponds to a symbol, also known as a chip. After receiving the signal within a symbol, the value of the bit corresponding to that symbol can be determined based on whether a signal has been emitted within that symbol.

[0085] In one example, when a signal is emitted within a certain symbol length (i.e., the signal power within that symbol length is not 0, or the signal within that symbol length is an ON signal), the bit corresponding to that symbol is "1". Conversely, when no signal is emitted within a certain symbol length (i.e., the signal power within that symbol length is 0, or the signal within that symbol length is an OFF signal), the bit corresponding to that symbol is "0". For example, when the received signal waveform is as shown in Figure 2, this waveform represents four bits "1010". In another example, the bit corresponding to a symbol with a signal emitted within its symbol length (i.e., the signal power within that symbol length is not 0) can also be determined as "0", and the bit corresponding to a symbol with no signal emitted within its symbol length (i.e., the signal power within that symbol length is 0) can be determined as "1". This application does not impose specific limitations on this.

[0086] In one possible implementation, after the WUR receives the OOK-modulated LP-WUS, it can demodulate the LP-WUS according to a threshold value. If the signal power (or signal amplitude) received by the WUR is higher than the threshold value within one 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.

[0087] In another possible implementation, LP-WUS can be a signal modulated by OOK using Manchester encoding. That is, the transmitter uses two OOK symbols to send one bit of original information. For example, Manchester encoding encodes 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 receiving the Manchester-encoded OOK-modulated LP-WUS, the WUR can compare the relative magnitudes of the signal power (or signal amplitude) within two adjacent symbols; if the signal power (or signal amplitude) in the preceding symbol is greater than the signal power (or signal amplitude) in the following symbol, the received bit is considered "0", otherwise it is considered "1".

[0088] 5.2FSK modulation

[0089] When FSK modulation is adopted in LP-WUS, different information can use different frequency resources. For example, 2FSK uses 2 frequency resources (i.e., frequency resource f0 and frequency resource f1) to carry 1 bit of information; when the bit value of the original information is 0, the information can be sent on frequency resource f0 and not sent on frequency resource f1; when the bit value of the original information is 1, the information can be sent on frequency resource f1 and not sent on frequency resource f0. Assuming f0 < f1, the FSK signal waveform of information 0101 is shown in Figure 3. The frequency of the signal is lower within the first symbol and the third symbol, and the frequency of the signal is higher within the second symbol and the fourth symbol.

[0090] In a possible implementation, FSK can also support higher modulation orders to carry more information. For example, 4FSK uses 4 candidate frequency domain resources (i.e., frequency resources f0 to f3) to carry 2 bits of information; when the original information bits are 00, the information can be sent on frequency resource f0 and not 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 not 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 not 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 not 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.

[0091] The above "frequency resource" can also be equivalently referred to as "frequency position".

[0092] 6. Monitoring methods for LP-WUS

[0093] The monitoring methods for the terminal device to monitor 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 times (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 on (i.e., on for some time or off for some time), and LP-WUS is only monitored at some possible transmission times of LP-WUS.

[0094] For example, the monitoring timing configured by the network device for terminal devices 1 to 4 is shown in 4a of Figure 4. For terminal device 1, if terminal device 1 monitors LP-WUS in a continuous monitoring manner, then as shown in 4b of Figure 4, the terminal device will monitor LP-WUS at all possible monitoring times; if terminal device 1 monitors LP-WUS in a duty cycle monitoring manner, then as shown in 4c of Figure 4, the terminal device will monitor LP-WUS at some possible monitoring times.

[0095] To improve the flexibility of LP-WUS monitoring in terminal devices using duty cycle monitoring, this application provides a wake-up signal monitoring method. The wake-up signal monitoring method and communication device provided in this application are described in detail below with reference to the accompanying drawings. Figure 5 is a flowchart illustrating a wake-up signal monitoring method provided in this application. As shown in Figure 5, the wake-up signal monitoring method includes the following steps S501 to S502. The method execution entities shown in Figure 5 are illustrated using a terminal device and a network device as examples. It can be understood that the method execution entities shown in Figure 5 can also be devices in the terminal device and devices in the network device, or devices used in conjunction with the terminal device and devices used in conjunction with the network device, such as a chip (system) in the terminal device and a chip (system) in the network device. The processing performed by a single execution entity shown in the embodiments of this application can also be divided into multiple execution entities, which can be logically and / or physically separated. For example, the processing performed by the network device can be divided into one or more execution entities among CU, DU, and RU.

[0096] in:

[0097] S501, the terminal device receives the first configuration information of LP-WUS, which is used to configure the first MO set and the second MO set. Correspondingly, the network device sends the first configuration information of LP-WUS.

[0098] The first configuration information is used to configure one or more of the following: a first monitoring period, a first monitoring offset value, and a first monitoring duration corresponding to the first MO set; the first configuration information is also used to configure one or more of the following: a second monitoring period, a second monitoring offset value, and a 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 and is a set of periodically occurring 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, where the first MO is a type of MO, and a single occurrence of the first MO can be considered an instance of the first MO, with the interval between the start times of two adjacent instances of the first MO being the first monitoring period of the first MO. Similarly, the second MO set can also be equivalently understood as the second MO, where the second MO is also a type of MO, and a single occurrence of the second MO can be considered an instance of the second MO, with the interval between the start times of two adjacent instances of the second MO being the second monitoring period of the second MO.

[0099] The network device sends first configuration information for LP-WUS to multiple terminal devices. Each terminal device determines a common first MO set and a second MO set corresponding to itself based on this first configuration information. It can be understood that different terminal devices (or terminal devices in different groups) can determine a common MO set (i.e., the first MO set) and a different MO set (i.e., the second MO set) based on this first configuration information. The first MO set is the common MO set shared by all terminal devices, meaning that all terminal devices can monitor LP-WUS based on this first MO set. The second MO set is a unique MO set corresponding to different terminal devices (or terminal devices in different groups), and each (or each group of) terminal device monitors LP-WUS based on its corresponding second MO set.

[0100] 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. As shown in Figure 6, terminal device 1 determines MO set 1 (i.e., the first MO set, composed of multiple MO 1s) and MO set 2 (i.e., the second MO set corresponding to terminal device 1, composed of multiple MO 2s) based on the first configuration information. Terminal device 2 determines MO set 1 (i.e., the first MO set, composed of multiple MO 1s) and MO set 3 (i.e., the second MO set corresponding to terminal device 2, composed of multiple MO 3s) based on the first configuration information.

[0101] In one possible implementation, the aforementioned first configuration information is used to configure the second monitoring period and / or the second monitoring duration. That is, if 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 identifier of the terminal device.

[0102] For example, the network device configures a common first MO set and N second MO sets for N terminal devices (or groups of N terminal devices) using first configuration information. This first configuration information does not include the second monitoring offset value corresponding to each of the second MO sets. In this case, the network device and the terminal devices can determine the second monitoring offset value corresponding to each terminal device according to Formula 1.

[0103] Second monitoring offset value = ID of terminal device % (N+1) (1)

[0104] In one possible implementation, the first configuration information can configure both the first and second monitoring periods using the same period configuration parameter. For example, the first configuration information includes a first period configuration parameter used to configure both the first and second monitoring periods; in this case, the first and second monitoring periods are the same. Alternatively, the first configuration information can also configure both the first and second monitoring periods using different period configuration parameters. For example, the first configuration information includes a second period configuration parameter and a third period configuration parameter, where 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 and second monitoring periods can be the same or different.

[0105] When the first monitoring period and the second monitoring period are the same, the second MO set does not overlap with the first MO set.

[0106] It is understood that when a network device configures N second MO sets and 1 first MO set for N terminal devices (or N groups of terminal devices), the MO sets do not overlap. That is, the first MO set does not overlap with any of the N second MO sets, and no two of the N second MO sets overlap. It should be noted that the non-overlapping mentioned in this application includes cases of complete non-overlap or partial non-overlap.

[0107] In one possible implementation, the first configuration information can configure both the first and second monitoring durations using the same duration configuration parameter. For example, the first configuration information includes a first duration configuration parameter used to configure both the first and second monitoring durations; in this case, the first and second monitoring durations are the same. Alternatively, the first configuration information can also configure both the first and second monitoring durations using different duration configuration parameters. For example, the first configuration information includes a second duration configuration parameter and a third duration configuration parameter, where 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 and second monitoring durations can be the same or different.

[0108] S502, the terminal device monitors LP-WUS according to the first MO set and the second MO set. Correspondingly, the network device sends LP-WUS according to the first MO set and the second MO set.

[0109] It is understandable that the network device configures N second MO sets and one first MO set for N terminal devices. For any given terminal device, the network device sends LP-WUS to that terminal device according to the second MO set and the first MO set corresponding to that terminal device, and the terminal device also monitors LP-WUS in its corresponding second MO set and first MO set.

[0110] For example, 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 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.

[0111] In one possible implementation, the terminal device includes a second LP-WUS based on the LP-WUS monitored by the second MO set. This second LP-WUS indicates wake-up information used to wake up the terminal device. Correspondingly, the network device includes this second LP-WUS in the LP-WUS sent based on the second MO set. This can be understood as the network device sending a second LP-WUS on the second MO corresponding to the terminal device to wake it up when it needs to do so (e.g., when a service arrives at the terminal device). The second LP-WUS may contain identification information related to the terminal device.

[0112] In one possible implementation, the LP-WUS monitored by the terminal device according to the first MO set includes a first LP-WUS, which indicates common information, including but not limited to one or more of the following: SI change, ETWS identifier, CMAS identifier, cell information, tracking area information, radio access network area information, ETWS information, CMAS information, and second configuration information of the LP-WUS. The second configuration information of the LP-WUS is the configuration information for the terminal device to subsequently monitor the LP-WUS. For example, if the terminal device receives the second configuration information of the LP-WUS in time slot n, the second configuration information of the LP-WUS can be made 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; before time slot n+X, the terminal device still monitors the LP-WUS according to the first configuration information.

[0113] In one possible implementation, in addition to monitoring the first LP-WUS according to the first MO set, the terminal device can also monitor a third LP-WUS according to the first MO set. This third LP-WUS indicates wake-up information, which is used to wake up the terminal device. It is understood that this third LP-WUS and the aforementioned second LP-WUS are of the same type, namely, LP-WUS indicating wake-up information. That is, for a given terminal device, the network device can send an LP-WUS indicating wake-up information to the terminal device according to the second MO set corresponding to that terminal device, or it can send an LP-WUS indicating wake-up information to the terminal device according to the common first MO set. Through this possible implementation, when there is no LP-WUS indicating common information being sent on the first MO set, the terminal device can be woken up according to the first MO set, which is beneficial for improving resource utilization.

[0114] It should be noted that the formats of the first LP-WUS, second LP-WUS, and third LP-WUS mentioned in this application may be the same or different, and this application does not impose specific limitations on this. Specifically, if two LP-WUS have different formats, it can be understood that the two LP-WUS carry completely different information or not entirely the same information.

[0115] In summary, the method shown in Figure 5 allows the terminal device to monitor LP-WUS based on multiple MO sets, which improves the flexibility of LP-WUS monitoring compared to monitoring LP-WUS based on only one MO set.
