Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a communication method, apparatus, and storage medium. Background Technology

[0002] Wake-up radio (WUR) technology can be understood as a technique to reduce the power consumption of terminal devices. For terminal devices, WUR refers to the introduction of a low-power (LP) interface on top of a traditional main radio (MR) module. This LP interface is implemented using simple circuits or chips, resulting in low power consumption. For example, an LP interface can be implemented using a wake-up receiver (WUR). The MR module can be used for data transmission. When there is no ongoing transmission on the MR module, it can enter a sleep state to minimize the power consumption of terminal devices supporting WUR. When there is a transmission requirement, the WUR module can receive a wake-up signal (WUS), which is used to wake up the MR module. Essentially, terminal devices supporting WUR have an MR module.

[0003] Terminal devices supporting WUR functionality can monitor wake-up signals on low-power wake-up signal occasions (LO). After acquiring the wake-up signal, the terminal device monitors paging messages on paging occasions (PO) to determine if it has been paged. If paged, it initiates a random access procedure. In one possible scenario, a terminal device supporting WUR functionality can obtain configuration information about the PO from system information block 1 (SIB 1), then determine the PO based on the terminal device's identifier, and further determine the LO based on the relative offset between the LO and the PO. Obviously, in this scenario, the wake-up signal and the paging message are on the same frequency band.

[0004] However, since wake-up signals and paging messages may be deployed on different frequency bands, and the subcarrier spacing configurations may differ across these bands, the corresponding orthogonal frequency division multiplexing (OFDM) symbol lengths and time slot lengths will also vary. This will affect the implementation of WUS functionality. For example, if the offset between LO and PO is too short, terminal devices supporting WUS functionality may miss the paging message monitoring opportunity; conversely, if the offset between LO and PO is too long, system latency will increase. Therefore, optimizing the implementation of WUS functionality and improving execution efficiency in scenarios with different subcarrier spacing configurations across different frequency bands is a pressing issue that needs to be addressed. Summary of the Invention

[0005] This application provides a communication method, apparatus, and storage medium to ensure optimized implementation of WUS function when wake-up signal and paging message are in different frequency bands.

[0006] Firstly, a communication method is provided, which can be applied to the terminal side, such as a terminal device or a module in the terminal device, or a circuit or chip in the terminal device. The following description uses the application of this method to a terminal device as an example.

[0007] The method includes: obtaining first configuration information corresponding to a first subcarrier interval, the first configuration information being used to indicate the correspondence between at least one LO and at least one PO, the first subcarrier interval including the subcarrier interval of WUR and / or the subcarrier interval of MR, the subcarrier interval of WUR and the subcarrier interval of MR being different; and determining the at least one LO and / or the at least one PO based on the first configuration information.

[0008] In this context, the subcarrier spacing of WUR can be understood as the subcarrier spacing of the frequency band to which LO belongs, and the subcarrier spacing of MR can be understood as the subcarrier spacing of the frequency band to which PO belongs.

[0009] The at least one LO includes one or more LOs, and the at least one PO includes one or more POs.

[0010] The correspondence between the at least one LO and the at least one PO may include: a one-to-one correspondence between the at least one LO and the at least one PO, or a correspondence between one LO and multiple POs, or a correspondence between one PO and multiple LOs.

[0011] The correspondence between the at least one LO and the at least one PO includes a correspondence in the time domain or a correspondence in the frequency domain.

[0012] The correspondence between the first subcarrier interval and the first configuration information can be predefined by the protocol or configured by the network device.

[0013] This application enables wake-up signals and paging messages in different frequency bands to function normally by configuring the correspondence between LO and PO under different subcarrier intervals, thereby improving the communication efficiency of the system.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the first configuration information includes an offset, which is an offset of the first LO relative to the first PO, or an offset of the first PO relative to the first LO, wherein the first LO is one of the at least one LO and the first PO is one of the at least one PO.

[0015] In this application, the at least one LO corresponds one-to-one with the at least one PO.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the first configuration information includes a plurality of offsets, the plurality of offsets including the offset of the at least one PO relative to the second LO, or the offset of the at least one LO relative to the second PO, wherein the second LO is one of the at least one LO and the second PO is one of the at least one PO.

[0017] In this application, since the cycles of LO and PO may be different, or the number of resources may be different, a mapping of one LO to multiple POs, or a mapping of one PO to multiple LOs, can be performed.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the offset is a time-domain offset. That is, one or more offsets in the aforementioned first configuration information are time-domain offsets.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the first configuration information includes a first offset set and / or a second offset set; the first offset set includes at least one first offset, one of which is the offset of a third LO relative to a first reference point, and the third LO is any one of the at least one LO; the second offset set includes at least one second offset, one of which is the offset of a third PO relative to a second reference point, and the third PO is any one of the at least one PO.

[0020] Wherein, when the first offset and the second offset are time-domain offsets, the first reference point and the second reference point are the same, and the first reference point or the second reference point can be uniformly referred to as the common reference point. That is, the first offset is the time-domain offset of the first LO relative to the common reference point, and the second offset is the time-domain offset of the first PO relative to the common reference point. Or, when the first offset and the second offset are frequency-domain offsets, the first reference point and the second reference point are different. That is, the first offset is the frequency-domain offset of the first LO relative to the first reference point, and the second offset is the frequency-domain offset of the first PO relative to the second reference point.

[0021] As an example, the reference point mentioned above can be a synchronization signal or a reference signal.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the at least one first offset corresponds one-to-one with the at least one second offset in sequence.

[0023] In conjunction with the first aspect, in some implementations of the first aspect, the first configuration information includes one or more of the following: the offset of the first monitoring time in at least one monitoring time relative to the third reference point; the offset between adjacent monitoring times in at least one monitoring time; or, the number of at least one monitoring time; the first monitoring time being one of the at least one monitoring times; the at least one monitoring time being the at least one LO, or the at least one monitoring time being the at least one PO.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the at least one LO is located within at least one discontinuous reception (DRX) cycle of the wake-up signal, and the at least one PO is located within at least one DRX cycle of the paging message.

[0025] The DRX cycle of the wake-up signal can be understood as the DRX cycle used to transmit the wake-up signal, or in other words, the wake-up signal can be transmitted within this DRX cycle. Similarly, the DRX cycle of the paging message can be understood as the DRX cycle used to transmit the paging message, or in other words, the paging message can be transmitted within this DRX cycle.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, before obtaining the first configuration information corresponding to the first subcarrier interval, the method further includes: receiving a first message, the first message including the first configuration information corresponding to the first subcarrier interval.

[0027] In conjunction with the first aspect, in some implementations of the first aspect, the first message is a radio resource control (RRC) message, a system message, or a medium access control element (MAC CE).

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the first message is a wake-up signal.

[0029] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: monitoring a wake-up signal on a fourth LO; monitoring a paging message on a PO corresponding to the fourth LO; wherein the wake-up signal and the paging message correspond to different frequency bands, and the fourth LO is any one of the at least one LO.

[0030] In conjunction with the first aspect, in some implementations of the first aspect, the wake-up signal and the paging message originate from different devices. For example, they may originate from different base stations, different TRPs, or different terminal devices.

[0031] Secondly, a communication method is provided that can be applied to the network side, such as a network device or a communication module in a network device, or a circuit or chip in a network device. The following description uses the application of this method to a network device as an example.

[0032] The method includes: determining first configuration information corresponding to a first subcarrier interval, the first configuration information being used to indicate the correspondence between at least one LO and at least one PO, the first subcarrier interval including the subcarrier interval of a wake-up radio (WUR) and / or the subcarrier interval of a master radio (MR), wherein the subcarrier interval of the WUR and the subcarrier interval of the MR are different; and sending a first message, the first message including the first configuration information corresponding to the first subcarrier interval.

[0033] In this context, the subcarrier spacing of WUR can be understood as the subcarrier spacing of the frequency band to which LO belongs, and the subcarrier spacing of MR can be understood as the subcarrier spacing of the frequency band to which PO belongs.

[0034] The at least one LO includes one or more LOs, and the at least one PO includes one or more POs.

[0035] The correspondence between the at least one LO and the at least one PO may include: a one-to-one correspondence between the at least one LO and the at least one PO, or a correspondence between one LO and multiple POs, or a correspondence between one PO and multiple LOs.

[0036] The correspondence between the at least one LO and the at least one PO includes a correspondence in the time domain or a correspondence in the frequency domain.

[0037] The correspondence between the first subcarrier interval and the first configuration information can be predefined by the protocol or configured by the network device.

[0038] This application enables wake-up signals and paging messages in different frequency bands to function normally by configuring the correspondence between LO and PO under different subcarrier intervals, thereby improving the communication efficiency of the system.

[0039] In conjunction with the second aspect, in some implementations of the second aspect, the first configuration information includes an offset, which is an offset of the first LO relative to the first PO, or an offset of the first PO relative to the first LO, wherein the first LO is one of the at least one LO and the first PO is one of the at least one PO.

[0040] In this application, the at least one LO corresponds one-to-one with the at least one PO.

[0041] In conjunction with the second aspect, in some implementations of the second aspect, the first configuration information includes a plurality of offsets, the plurality of offsets including the offset of the at least one PO relative to the second LO, or the offset of the at least one LO relative to the second PO, wherein the second LO is one of the at least one LO and the second PO is one of the at least one PO.

[0042] In this application, since the cycles of LO and PO may be different, or the number of resources may be different, a mapping of one LO to multiple POs, or a mapping of one PO to multiple LOs, can be performed.

[0043] In conjunction with the second aspect, in some implementations of the second aspect, this offset is a time-domain offset. That is, one or more offsets in the aforementioned first configuration information are time-domain offsets.

[0044] In conjunction with the second aspect, in some implementations of the second aspect, the first configuration information includes a first offset set and / or a second offset set; the first offset set includes at least one first offset, one of which is the offset of a third LO relative to a first reference point, and the third LO is any one of the at least one LO; the second offset set includes at least one second offset, one of which is the offset of a third PO relative to a second reference point, and the third PO is any one of the at least one PO.

[0045] Wherein, when the first offset and the second offset are time-domain offsets, the first reference point and the second reference point are the same, and the first reference point or the second reference point can be uniformly referred to as the common reference point. That is, one of the at least one first offsets is the time-domain offset of the first LO relative to the common reference point, and one of the at least one second offsets is the time-domain offset of the first PO relative to the common reference point. Alternatively, when the first offset and the second offset are frequency-domain offsets, the first reference point and the second reference point are different. That is, one of the at least one first offsets is the frequency-domain offset of the first LO relative to the first reference point, and one of the at least one second offsets is the frequency-domain offset of the first PO relative to the second reference point.

[0046] As an example, the reference point mentioned above can be a synchronization signal or a reference signal.

[0047] In conjunction with the second aspect, in some implementations of the second aspect, the at least one first offset corresponds one-to-one with the at least one second offset in sequence.

[0048] In conjunction with the second aspect, in some implementations of the second aspect, the first configuration information includes one or more of the following: the offset of the first monitoring time in at least one monitoring time relative to the third reference point; the offset between adjacent monitoring times in at least one monitoring time; or, the number of at least one monitoring time; the first monitoring time being one of the at least one monitoring times; the at least one monitoring time being the at least one LO, or the at least one monitoring time being the at least one PO.

[0049] In conjunction with the second aspect, in some implementations of the second aspect, the at least one LO is located within at least one DRX cycle of the wake-up signal, and the at least one PO is located within at least one DRX cycle of the paging message.

[0050] The DRX cycle of the wake-up signal can be understood as the DRX cycle used to transmit the wake-up signal, or in other words, the wake-up signal can be transmitted within this DRX cycle. Similarly, the DRX cycle of the paging message can be understood as the DRX cycle used to transmit the paging message, or in other words, the paging message can be transmitted within this DRX cycle.

[0051] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending a first message, the first message including the first configuration information corresponding to the first subcarrier interval.

[0052] In conjunction with the second aspect, in some implementations of the second aspect, the first message is an RRC message, a system message, or a MAC CE.

[0053] In conjunction with the second aspect, in some implementations of the second aspect, the first message is a wake-up signal.

[0054] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending a wake-up signal on the fourth LO; sending a paging message on the PO corresponding to the fourth LO; wherein the wake-up signal and the paging message correspond to different frequency bands, and the first LO is any one of the at least one LO.

[0055] It should be understood that the second aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0080] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0081] Before introducing the communication method and related apparatus provided in the embodiments of this application, the following points should be made first.

[0082] First, in the embodiments shown below, the terms and English abbreviations, such as Wake-up Signal (WUS), Wake-up Radio (WUR), Low-Power Wake-up Timing (LP), Paging Timing (PO), Subcarrier Spacing, etc., are merely exemplary examples given for ease of description and should not constitute any limitation on this application. This application does not preclude the possibility of defining other terms that can achieve the same or similar functions in existing or future protocols.

[0083] Second, in the embodiments shown below, the terms "first," "second," and various numerical designations are merely for descriptive convenience to distinguish identical or similar items with substantially the same function and purpose. For example, "first LO" and "second LO" are only used to distinguish different LOs and do not limit their order, nor are they used to limit the scope of the embodiments of this application. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., are not necessarily different.

[0084] Third, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0085] Fourth, in this application, "instruction" can include direct and indirect instructions, explicit and implicit instructions, and instructions used for determination. When describing certain instruction information to indicate A, it can be understood that the instruction information carries A, directly indicates A, or indirectly indicates A. In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementation, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information to be sent separately, and the sending period and / or timing of these sub-information can be the same or different. This application does not limit the specific method of instruction. It is understood that, for the sender of the instruction information, the instruction information can be used to indicate the information to be indicated, and for the receiver of the instruction information, the instruction information can be used to determine the information to be indicated.

[0086] The information in this application is used to indicate one or more contents, or it may be replaced with the information indicating one or more contents, or the information including one or more contents.

[0087] Fifth, in this application, "when," "if," and "if" all refer to the device taking corresponding actions under certain objective circumstances, not to a time limit, nor do they require the device to perform a judgment action, nor do they imply any other limitations. Unless otherwise specified, "if" and "if" are interchangeable, and "when" and "under the circumstances" are interchangeable. "When" is interchangeable with "if" / "if."

[0088] Sixth, in this application, "time domain unit" refers to a time unit in general. A time domain unit can be granular, including radio frames, subframes, slots, mini-slots, OFDM symbols, etc. Specifically, a radio frame may include multiple subframes (e.g., 10 subframes), a subframe may include one or more slots (e.g., 1, 2, 4, 6, or 18), and a slot may include at least one symbol (e.g., 12 or 14). The term "time domain unit" can also be used interchangeably with "time unit."

[0089] Seventh, in this application, frequency domain unit refers to frequency domain unit in general. Frequency domain unit can be at the granularity of resource element (RE), physical resource block (PRB), subcarrier, or resource block group (RBG).

[0090] Eighth, in this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0091] Ninth, "Sending information / data" only indicates the direction of information / data transmission, including direct transmission via the device's communication interface (such as an air interface). "Sending" can also be understood as the "output" of the module interface. "Sending" can include indirect transmission by the processing unit through the communication interface, that is, after the processing unit outputs information / data through the module interface, it is transmitted to the device's communication interface and then sent out. "Receiving information / data" only indicates the direction of information / data transmission, including direct reception via the communication interface. "Receiving" can also be understood as the "input" of the module interface. "Receiving information / data" can include indirect reception by the processing unit through the communication interface, that is, after the communication interface receives information / data, it is transmitted to the module interface of the processing unit and then input to the processing unit. "Sending information / data to… (such as a terminal device)" can be understood as the destination of the information being the terminal device. It can include sending information / data directly or indirectly to the terminal device. "Receiving information / data from… (such as a terminal device)" can be understood as the source of the information being the terminal device, and can include receiving information / data directly or indirectly from the terminal device. Information / data may undergo necessary processing, such as format changes, between the source and destination, but the destination can understand the valid information / data from the source. Similar statements in this application can be understood in a similar way, and will not be repeated here.

[0092] In other words, sending and receiving can occur between devices, such as between terminal devices and network devices; or they can occur within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0093] Tenth, in this application, the solutions in each embodiment can be used in a reasonable combination, and the explanations or descriptions of various terms, similar operations, or steps appearing in the embodiments can be referenced or explained to each other in the various embodiments, without limitation.

[0094] Figure 1 This is a schematic diagram of the architecture of the communication system used in the embodiments of this application. Figure 1 A schematic diagram of a possible, non-limiting system architecture is shown. (e.g.) Figure 1 As shown, the communication system 100 includes a radio access network (RAN) 10 and a core network 20. Optionally, the communication system 100 also includes an Internet 30. The radio access network 10 may include at least one access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal (such as Figure 1(Referring to devices 120a-120j). Terminals connect wirelessly to access network equipment, which in turn connects wirelessly or via wired connection to the core network 20. Core network equipment and access network equipment can be independent physical devices, or they can integrate the functions of core network equipment and access network equipment onto the same physical device. Alternatively, a single physical device can integrate some core network equipment functions and some access network equipment functions. Terminals and access network equipment can connect to each other via wired or wireless means. Figure 1 This is just an illustration; the communication system may also include other access network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 Not shown in the image.

[0095] The radio access network 10 can be a cellular system related to the 3rd generation partnership project (3GPP), such as a 4th generation mobile communication technology (4G) system (also known as a long term evolution (LTE) system), a 5th generation mobile communication technology (5G) system (also known as a new radio (NR) system), or it can be applied to future mobile communication systems or other similar communication systems, without specific limitations. The radio access network 10 can also be an open radio access network (open RAN, O-RAN, or ORAN), a cloud radio access network (CRAN), a non-terrestrial network (NTN), a satellite communication network, a high altitude platform station (HAPS) communication network, an integrated access and backhaul (IAB) communication network, a reconfigurable intelligent surface (RIS) communication network, etc. The wireless access network 10 can also be a communication system that integrates two or more of the above systems.

[0096] Access network devices are nodes in a radio access network, also known as RAN nodes or RAN equipment. Access network devices assist terminals in achieving wireless access. Multiple access network devices in communication system 100 can be nodes of the same type or different types.

[0097] In one possible scenario, access network equipment can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, an access point (AP) in a satellite, an integrated access and backhaul (IAB) node, or access network equipment in a mobile switching center non-terrestrial network (NTN) communication system. This means it can be deployed on high-altitude platforms or satellites. Access network equipment can also be a macro base station (such as...). Figure 1 110a), micro base stations or indoor stations (such as Figure 1 Access network equipment can be 110b), relay nodes or donor nodes, or wireless controllers in CRAN scenarios. It can also function as a base station in device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, drone communication, or machine-to-machine (M2M) communication. Optionally, access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU).

[0098] In another possible scenario, multiple access network devices collaborate to assist terminals in achieving wireless access, with each access network device implementing a portion of the base station's functions. For example, access network devices can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that access network devices can be CU nodes, DU nodes, or devices including both CU and DU nodes. Furthermore, CUs can be classified as access network devices within the RAN (RAN) or as access network devices within the core network; no restrictions are placed here.

[0099] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an O-RAN system, CU can also be called O-CU (Open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0100] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from access network equipment. Terminals can also be referred to as terminal devices, terminal equipment, user equipment (UE), mobile stations, mobile terminals, etc.

[0101] For example, terminal devices include handheld devices and in-vehicle devices with wireless connectivity. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices (such as smartwatches, smart bracelets, pedometers, smart glasses, etc.), in-vehicle devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, point-of-sale (POS) machines, customer-premises equipment (CPE), light user equipment (UE), reduced capability user equipment (REDCAP UE), wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, and flying equipment (such as intelligent robots, hot air balloons, drones, airplanes), etc. Terminal devices can also be vehicle devices, such as vehicle devices, vehicle modules, vehicle chips, on-board units (OBUs) or telematics boxes (T-BOXs). Terminal devices can also be other devices with terminal functions. For example, a terminal device can also be a device that performs terminal functions in D2D communication.

[0102] The embodiments of this application do not limit the form of the terminal device. The device used to implement the functions of the terminal device can be the terminal device itself, or it can be a device that supports the terminal device in implementing the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of chips, or it can include chips and other discrete devices. All or part of the functions of the terminal device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

[0103] Terminal devices can be widely used in various scenarios, such as D2D, V2X communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart cities, etc.

[0104] Access network devices and terminals can be fixed in location 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 access network devices and terminals.

[0105] The roles of access network devices and terminals can be relative. For example, Figure 1 The helicopter or drone 120i can be configured as a mobile access network device. For terminals 120j accessing the wireless access network 10 via 120i, terminal 120i is an access network device; however, for access network device 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Alternatively, 110a and 120i can also communicate via an interface protocol between access network devices; in this case, 120i is also an access network device relative to 110a. Therefore, both access network devices and terminals can be collectively referred to as communication devices. Figure 1 110a and 110b can be referred to as communication devices with access network equipment functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0106] Communication between access network devices and terminals, between access network devices, 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.

[0107] In the embodiments of this application, the functions of the access network device can be executed by modules (such as chips) within the access network device, or by a control subsystem that includes access network device functions. This control subsystem, including access network device 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.

[0108] In this application, the access network device sends downlink (DL) signals or downlink information to the terminal, which are carried on the downlink channel; the terminal sends uplink (UL) signals or uplink information to the access network device, which are carried on the uplink channel. To communicate with the access network device, the terminal can establish a radio connection on a cell controlled by the access network device. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with the serving cell, it may also be subject to interference from signals from neighboring cells.

[0109] In this application, the time-domain symbol can be an OFDM symbol or a Discrete Fourier Transform-Spread-OFDM (DFT-s-OFDM) symbol. Unless otherwise specified, the symbols used in the embodiments of this application refer to time-domain symbols.

[0110] It is understood that in the embodiments of this application, the physical downlink shared channel (PDSCH) and the physical downlink control channel (PDCCH) are only examples of downlink data channels and downlink control channels, respectively. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of this application do not limit this.

[0111] For ease of understanding, the relevant technologies and concepts involved in this application are introduced below.

[0112] 1. Wake-up Radio (WUR)

[0113] Wake-up radio technology can be understood as a technique to reduce the power consumption of terminal devices. For terminal devices, wake-up radio refers to introducing an LP interface on top of the MR module. This LP interface is implemented through a simple circuit or chip with low power consumption. This application does not limit the specific form of the LP interface; for example, the LP interface can be implemented through a low-power wake-up receiver (LP-WUR), a wake-up receiver, a low-power radio (LR), a wake-up module, or a wake-up circuit.

[0114] In this document, WUR can refer to a wake-up radio or a wake-up receiver. WUR can be replaced with LP-WUR, LR, wake-up module, wake-up circuit, or other devices that perform similar functions.

[0115] The MR module can be used for data transmission. When there is no ongoing transmission service on the MR module, or no transmission service requirement, the MR module can enter a shutdown, sleep, or hibernation state to minimize the power consumption of terminal devices supporting the WUR function. When there is a transmission service requirement, the WUR module can be used to wake up the MR module in the shutdown, sleep, or hibernation state.

[0116] In this application, the MR module can also be described as an MR circuit or an MR device, and the WUR module can also be described as a WUR circuit or a WUR device.

[0117] See Figure 2 The diagram shows the wake-up mechanism of the MR module. The signal received by the WUR module by the terminal device supporting the WUR function can be called the wake-up signal. When the WUR module detects / receives the wake-up signal, it can wake up the MR module that is in a closed, sleep, or hibernation state.

[0118] A wake-up signal can be understood as a signal sent by the network side using a specific frequency, transmitter, and receiver to wake up the terminal device and enable it to receive paging messages. A paging message is a message sent by the network side to the terminal device when it needs to establish an RRC connection.

[0119] It should be noted that the terminal device in this application is a terminal device that supports / has WUR functionality.

[0120] It is understood that this application does not limit the type of wake-up signal. For example, the wake-up signal can be a low-power wake-up signal (LP-WUS), a low-power PDCCH signal, a low-power PDSCH signal, a low-power physical uplink shared channel (PUSCH) signal, a low-power physical uplink control channel (PUCCH) signal, a low-power synchronization signal / physical broadcast channel block (SSB) signal, a low-power synchronization signal (LP-SS), a low-power tracking reference signal (TRS), a low-power channel status information reference signal (CSI-RS), a low-power positioning signal, a low-power sensing communication signal, a low-power sounding reference signal (SRS) signal, a low-power random access channel (RACH) signal, a low-power preamble signal, a low-power contention resolution message, a low-power downlink control information (DCI) signal, or a low-power uplink control information (UCI) signal, etc.

[0121] WUS bit information can be mapped to time units in various ways, or in other words, WUS bit information can be modulated in various ways. For example, the modulation method is on-off keying (OOK), and correspondingly, the WUR module in a terminal device with WUS functionality receives WUS using envelope detection. As another example, the modulation method is OFDM, and correspondingly, the WUR module in a terminal device with WUS functionality receives WUS using phase detection.

[0122] OOK modulation uses the presence or absence of a signal to represent digital information. The bit information corresponding to a signal is mapped to at least one time unit through OOK modulation. One time unit corresponds to one bit of information, and the bit information is determined by detecting whether there is a signal in the time unit. A time unit with a signal means that the signal amplitude is not zero; this time unit is also called an ON time unit, or the time unit is in ON mode. Conversely, a time unit without a signal means that the signal amplitude is zero; this time unit is also called an OFF time unit, or the time unit is in OFF mode. Generally, if a sequence is transmitted in a time unit, then that time unit has a signal; if no sequence is transmitted in a time unit, then that time unit has no signal. For a given time unit, being ON or in ON mode can be decoded as 1; conversely, being OFF or in OFF mode can be decoded as 0.

[0123] The modulation method of WUS can be a combination of the above modulation methods. For example, it can be a modulation method that combines OOK and OFDM. It can be simply understood as fusing / superimposing OFDM sequences on the time unit where there is a signal.

[0124] 2. DRX Mechanism

[0125] In wireless communication systems, without a DRX mechanism, terminal devices continuously monitor the PDCCH and / or PDSCH to detect information from the serving cell. However, in reality, terminal devices often do not continuously exchange information with network devices, do not continuously perform data upload or download operations, and do not continuously transmit voice data during calls. If the terminal device continues to monitor the PDCCH and / or PDSCH when there is no data exchange with the network device, it will increase the power consumption of the terminal device. Therefore, to save power consumption of the terminal device while ensuring effective data transmission, a DRX mechanism can be introduced to control the terminal device's monitoring behavior of the PDCCH and / or PDSCH. It should be noted that the following... Figure 4 The following explanation uses the monitoring of PDCCH by Chinese and Israeli terminal equipment as an example.

[0126] When DRX is configured, the terminal device can periodically enter a sleep state for a period of time. During this period, the terminal device does not need to monitor PDCCH and / or PDSCH. When it is necessary to monitor PDCCH and / or PDSCH, the terminal device wakes up from the sleep state, which can save the power consumption of the terminal device.

[0127] 3. Paging process

[0128] In one possible paging implementation, the terminal device blindly checks DCI 1_0 using the paging radio network temporary identifier (P-RNTI) on a pre-configured time-frequency resource (i.e., paging opportunity) on the PDCCH to determine the time-frequency resource of the PDSCH, thereby obtaining the paging message. If the paging message includes the terminal device's own identifier, the terminal device can initiate a random access procedure. Before this, the terminal device can receive SSB to obtain synchronization information and system messages.

[0129] Figure 3 This diagram illustrates a paging process based on a wake-up signal. The wake-up signal can be viewed as a new DCI format, namely DCI 2_6, where it triggers the monitoring of the PDCCH or paging messages. In this wake-up signal-based paging process, the terminal device can use a power-saving radio network temporary identifier (PS-RNTI) to blindly detect the wake-up signal on the PDCCH. The wake-up signal includes 1 bit of information to indicate whether PDCCH monitoring is required during the DRX period, and up to 5 bits of information to indicate the activation of the secondary cell (SCell) function. If the wake-up signal indicates that PDCCH monitoring is required during the DRX period, the terminal device monitors the PDCCH during the active period of the DRX period and can then initiate a random access procedure. If the wake-up signal indicates that PDCCH monitoring is not required, the terminal device will not monitor the PDCCH during the DRX period and will not receive paging messages, thus achieving energy saving.

[0130] Figure 4 This is a schematic diagram of a wake-up signal function within a DRX cycle. For example... Figure 4 As shown, DRX is implemented periodically. A DRX cycle includes an active time and a non-active time. During the active time, the terminal device can monitor the PDCCH, and during the non-active time, it enters a sleep state and monitors for wake-up signals on a lower frequency band. During the non-active time, the terminal device monitors for wake-up signals on a certain time-frequency resource (i.e., LO). If the wake-up signal indicates that the PDCCH should be monitored, the terminal device uses P-RNTI to blindly check the PDCCH on the corresponding PO to receive paging messages and determine whether it has been paged. If it has been paged, it initiates a random access procedure. If the wake-up signal does not indicate that the PDCCH should be monitored, the terminal device also enters a sleep state during the originally scheduled active time, thereby saving power.

[0131] In one possible implementation, the terminal device can obtain configuration information about the PO from SIB 1, then determine the PO based on the identifier of the terminal device, and then determine the LO based on the relative offset between the LO and the PO.

[0132] Current technology focuses on configuring the relative offsets of LO and PO in the time or frequency domain, thereby directly determining PO or LO. (See also...) Figure 5 The diagram shows the relative positions of LO and PO in the time domain. The wake-up signal and paging message DCI share the same bandwidth. The protocol configures the time domain resources of LO and the time offset of PO relative to LO. The terminal device monitors the wake-up signal on the time-frequency resources of LO. If the wake-up signal indicates monitoring PDCCH, the terminal device monitors the paging message after the configured offset.

[0133] However, the above method of configuring the relative positions of LO and PO does not take into account the multi-band cross-band technology that will be widely adopted in the future. That is, wake-up signals and paging messages may be deployed on different frequency bands, and the subcarrier spacing configuration of different frequency bands is different. The corresponding orthogonal frequency division multiplexing (OFDM) symbol length and time slot length will also change.

[0134] If a uniform offset configuration is used regardless of the subcarrier spacing configuration, meaning the offset is the same for different subcarrier spacing configurations, the following problems may occur:

[0135] 1) When the subcarrier spacing of the WUR and / or MR is large, the larger the subcarrier spacing, the shorter the corresponding OFDM symbol length and time slot length. Therefore, if the LO and PO are too close in time, the terminal equipment may miss the PO due to signal processing delays and other reasons, and thus fail to receive the paging message. Here, the subcarrier spacing of the WUR refers to the subcarrier spacing of the frequency band to which the wake-up signal / LO belongs, and the subcarrier spacing of the MR refers to the subcarrier spacing of the frequency band to which the paging message / PO belongs.

[0136] 2) If a large offset is uniformly configured, there will be a large redundancy in time when the subcarrier spacing of WUR or MR is small, which will increase the system latency.

[0137] 3) The length of LO will change for different subcarrier spacings of WUR. Similarly, the length of PO will change for different subcarrier spacings of MR. Therefore, in the case of beam scanning, using a uniform configuration may cause the terminal equipment to be unable to accurately determine PO.

[0138] Therefore, for scenarios where wake-up signals and paging messages use different frequency bands, how to configure the mapping relationship between LO and PO to improve communication efficiency is an urgent problem to be solved.

[0139] In view of this, embodiments of this application provide a communication method in which different correspondences between LO and PO are configured for different subcarrier intervals, so as to adapt to the impact of different subcarrier intervals on the system under different frequency bands and improve communication performance.

[0140] Figure 6 This is a schematic flowchart of a communication method 600 provided in an embodiment of this application. The steps of method 600 can be interactively executed by a terminal device (or modules within the terminal device, such as processors, chips, chip systems, circuits, etc.) and a network device (or modules within the network device, such as processors, chips, chip systems, circuits, etc.). The following description uses a terminal device and a network device as examples. Furthermore, the processing performed by a single execution entity 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 execution by at least one of CU, DU, RU, etc.

[0141] Method 600 includes, but is not limited to, S601 and S604, and each step will be described in detail below.

[0142] S601, obtain the first configuration information corresponding to the first subcarrier interval. The first configuration information is used to indicate the correspondence between at least one LO and at least one PO. The first subcarrier interval includes the subcarrier interval of WUR and / or the subcarrier interval of MR. The subcarrier interval of WUR and the subcarrier interval of MR are different.

[0143] It is understood that the above S601 can be executed by the terminal device. Here, LO is the timing for transmitting a wake-up signal; that is, the terminal device can monitor for a wake-up signal on LO, and the network device can send a wake-up signal on LO. PO is the timing for transmitting a paging message; that is, the terminal device can monitor for a paging message on PO, and the network device can send a paging message on PO.

[0144] In one possible implementation, the LO belongs to the first frequency band, and the PO belongs to the second frequency band. The first frequency band and the second frequency band are different.

[0145] In one possible implementation, the first frequency band is a low frequency band, that is, the terminal device monitors the wake-up signal on the LO of the low frequency band, such as 700-900MHz or frequency range 1 (FR1); the second frequency band is a high frequency band, that is, the terminal device monitors the paging message on the PO of the high frequency band, such as 6GHz or frequency range 2 (FR2).

[0146] The low-frequency band can also be described as the long-wave band, and the high-frequency band can also be described as the short-wave band.

[0147] The subcarrier spacing of WUR refers to the subcarrier spacing of the frequency band to which LO belongs, while the subcarrier spacing of MR refers to the subcarrier spacing of the frequency band to which PO belongs. It can be understood that since the terminal device monitors the wake-up signal on LO through the WUR module, and when the wake-up signal indicates the need to monitor PDCCH, the terminal device monitors the paging message on PO through the MR module. Therefore, the subcarrier spacing of the frequency band to which LO belongs can be described as the subcarrier spacing of WUR, and the subcarrier spacing of the frequency band to which PO belongs can be described as the subcarrier spacing of MR.

[0148] The formula for calculating the subcarrier spacing is, for example: Δf = 2 μ ×15kHz, where Δf is the subcarrier spacing, and μ is a parameter set. For low-frequency bands, μ takes values ​​of 0 or 1, for example, and for high-frequency bands, μ takes values ​​of 2 or 3, for example. This formula is applicable to frequency bands below terahertz.

[0149] The at least one LO includes one or more LOs, and the at least one PO includes one or more POs.

[0150] The correspondence between the at least one LO and the at least one PO may include: a one-to-one correspondence between the at least one LO and the at least one PO, or a correspondence between one LO and multiple POs, or a correspondence between one PO and multiple LOs.

[0151] The correspondence between the at least one LO and the at least one PO includes a correspondence in the time domain and / or a correspondence in the frequency domain.

[0152] The following describes in detail how the first configuration information indicates the correspondence between the at least one LO and the at least one PO.

[0153] In one implementation method, the first configuration information includes an offset, which is either the offset of the first LO relative to the first PO, or the offset of the first PO relative to the first LO, where the first LO is one of the at least one LOs and the first PO is one of the at least one POs. In other words, the offset indicates a one-to-one correspondence between the at least one LO and the at least one PO.

[0154] The offset of the first LO relative to the first PO can be the offset of the start time of the first LO relative to the start time of the first PO, or the offset of the end time of the first LO relative to the end time of the first PO, or the offset of the start time of the first LO relative to the end time of the first PO, or the relative offset of the end time of the first LO relative to the start time of the first PO.

[0155] Similarly, the offset of the first PO relative to the first LO can be the offset of the start time of the first PO relative to the start time of the first LO, or the offset of the end time of the first PO relative to the end time of the first LO, or the offset of the start time of the first PO relative to the end time of the first LO, or the relative offset of the end time of the first PO relative to the start time of the first LO.

[0156] If the offset is determined based on the start time of the first LO and / or the first PO, the time positioning is more accurate, and the delay of receiving the wake-up signal and / or paging message can be ignored. If the offset is determined based on the end time of the first LO and / or the first PO, the length of the first LO and / or the first PO can be ignored, and the offset can more accurately correspond to the system delay. This is because the system delay is relatively stable, while the duration of the first LO and the first PO will change with the subcarrier interval.

[0157] It should be noted that in this implementation, the offset in the first configuration information is a time-domain offset.

[0158] For example Figure 7 As shown, the at least one LO includes LO 1, LO 2, and LO 3, and the at least one PO includes PO 1, PO 2, and PO 3. Taking the offset between LO 1 and PO 1 as an example, the offset between LO 1 and PO 1 can be the offset between the start time of LO 1 and the start time of PO 1, including N1 time domain units; or, the offset between LO 1 and PO 1 can be the offset between the end time of LO 1 and the end time of PO 1, including N2 time domain units; or, the offset between LO 1 and PO 1 can be the offset between the start time of LO 1 and the end time of PO 1, including N3; or, the offset between LO 1 and PO 1 can be the offset between the end time of LO 1 and the start time of PO 1, including N4 time domain units.

[0159] Similarly, LO 2 corresponds to PO 2. The offset between LO 2 and PO 2 can be the offset between the start time of LO 2 and the start time of PO 2, or the offset between the end time of LO 2 and the end time of PO 2, or the offset between the start time of LO 2 and the end time of PO 2, or the offset between the end time of LO 2 and the start time of PO 2. Figure 7 The offset between LO 2 and PO 2 shown is the offset between the start time of LO 2 and the start time of PO 2; other cases are not shown.

[0160] Similarly, LO 3 corresponds to PO 3. The offset between LO 3 and PO 3 can be the offset between the start time of LO 3 and the start time of PO 3, or the offset between the end time of LO 3 and the end time of PO 3, or the offset between the start time of LO 3 and the end time of PO 3, or the offset between the end time of LO 3 and the start time of PO 3. Figure 7 The offset between LO 3 and PO 3 shown is the offset between the start time of LO 3 and the start time of PO 3; other cases are not shown.

[0161] It is understandable that the offsets between LO 1 and PO 1, between LO 2 and PO 2, and between LO 3 and PO 3 can be the same or different.

[0162] The correspondence between the first subcarrier interval and the first configuration information can be predefined by the protocol. For example, it can be indicated in the form of a configuration table, showing the correspondence between the first subcarrier interval (e.g., the subcarrier interval of WUR and / or the subcarrier interval of MR) and the first configuration information. For example, Table 1 indicates the correspondence between multiple sets of subcarrier intervals and time-domain offsets, where the first subcarrier interval is one set of subcarrier intervals, and the first configuration information includes a time-domain offset N in Table 1. It can be understood that the time-domain offset N in Table 1 can be the offset of PO relative to LO, or the offset of LO relative to PO.

[0163] Referring to Table 1, if the first subcarrier spacing includes the subcarrier spacing of WUR and the subcarrier spacing of MR, where the subcarrier spacing of WUR is 30kHz and the subcarrier spacing of MR is 15kHz, then the time-domain offset corresponding to the first subcarrier spacing includes 8 time-domain units. That is to say, the relative offset between the first LO and the first PO is 8 time-domain units.

[0164] It is understandable that time-domain units can be granular, such as radio frames, subframes, time slots, mini-time slots, OFDM symbols, etc.

[0165] Table 1

[0166] WUR subcarrier spacing Subcarrier spacing of MR Time domain offset N 15kHz 15kHz 6 30kHz 15kHz 8 15kHz 30kHz 10 … … …

[0167] The correspondence between the first subcarrier interval and the first configuration information can also be indicated by the network device. For example, the network device may indicate the first configuration information through SIB 1, OSI, RRC messages, MAC CE, etc. The configuration content can be a configuration table as shown in Table 1, or it can be the corresponding signaling, with the signaling format as follows:

[0168] LO-PO-config:=

[0169] {WUR-SCS15,30,…

[0170] MR-SCS15,30,…

[0171] offset 6,8,10,…};

[0172] In addition, network devices can also dynamically indicate the first configuration information based on the actual subcarrier spacing. As an example, the first configuration information can be carried in the wake-up signal, and its signaling format is, for example, LO-PO-config:={LO-PO-offset Integer}, where “offset” represents the time-domain offset and “Integer” represents the value of the time-domain offset.

[0173] It should be noted that in the correspondence between subcarrier spacing and time-domain offset shown in Table 1, the subcarrier spacing includes the subcarrier spacing of WUR and the subcarrier spacing of MR. In other implementations, the correspondence between the subcarrier spacing of WUR and the time-domain offset can be configured only, or the correspondence between the subcarrier spacing of MR and the time-domain offset can be configured only.

[0174] In a subcarrier spacing scheme that includes both WUR and MR subcarrier spacing, the subcarrier spacing of WUR and MR differs, and the corresponding time slot lengths also differ. For example, a subcarrier spacing of 15kHz corresponds to a time slot length of 1ms, a subcarrier spacing of 30kHz corresponds to a time slot length of 0.5ms, a subcarrier spacing of 60kHz corresponds to a time slot length of 0.25ms, and a subcarrier spacing of 120kHz corresponds to a time slot length of 0.125ms. Therefore, assuming the time domain offset includes N time slots, the time slot length can be either the time slot length corresponding to the WUR subcarrier spacing or the time slot length corresponding to the MR subcarrier spacing. It is understood that the time slot length refers to the length of one time slot.

[0175] In one possible implementation, if the terminal device completes synchronization based on the synchronization signal of the frequency band to which the LO belongs, then the time slot length is the time slot length corresponding to the subcarrier interval of the WUR. Similarly, if the terminal device completes synchronization based on the synchronization signal of the frequency band to which the PO belongs, then the time slot length is the time slot length corresponding to the subcarrier interval of the MR.

[0176] In another possible implementation, when configuring the relative offsets of LO and PO, if the offset of PO relative to LO is configured based on LO, then the time slot length is the time slot length corresponding to the subcarrier interval of WUR; if the offset of LO relative to PO is configured based on PO, then the time slot length is the time slot length corresponding to the subcarrier interval of MR.

[0177] The value of the time domain offset can be determined based on the length of LO and / or PO, system latency, and the latency of transceiver adjustment, so as to avoid missing the monitoring opportunities of LO and / or PO.

[0178] In this application, monitoring can also be described as receiving or detecting.

[0179] In the above configuration, the time-domain offset is 8 for the case where the subcarrier spacing of WUR is 30kHz and the subcarrier spacing of MR is 15kHz, and the time-domain offset is 10 for the case where the subcarrier spacing of WUR is 15kHz and the subcarrier spacing of MR is 30kHz. This is because if the offset is defined as the offset between the start time of LO and the start time of PO, then the offset includes the length of LO. When the subcarrier spacing of WUR is 30kHz, the length of LO is smaller, and when the subcarrier spacing of WUR is 15kHz, the length of LO is larger. Therefore, the offset when the subcarrier spacing of WUR is 30kHz and the subcarrier spacing of MR is 15kHz is smaller than the offset when the subcarrier spacing of WUR is 15kHz and the subcarrier spacing of MR is 30kHz.

[0180] Furthermore, if the offset is considered as the offset between the end time of LO and the start time of PO, the lengths of LO and PO can be ignored. The same offset can be configured for both cases where the subcarrier spacing of WUR is 30kHz and the subcarrier spacing of MR is 15kHz, and for WUR with a subcarrier spacing of 15kHz and MR with a subcarrier spacing of 30kHz.

[0181] In the second implementation method, the first configuration information includes a first offset set and a second offset set. The first offset set includes at least one first offset, one of which is the offset of the third LO relative to the first reference point, and the third LO is any one of the at least one LO. The second offset set includes at least one second offset, one of which is the offset of the third PO relative to the second reference point, and the third PO is any one of the at least one PO.

[0182] In this set, at least one first offset in the first offset set corresponds one-to-one with the at least one LO, and the at least one first offset is different from each other; at least one second offset in the second offset set corresponds one-to-one with the at least one PO, and the at least one second offset is different from each other.

[0183] It should be noted that in this implementation, the first offset and the second offset are time-domain offsets, or the first offset and the second offset are frequency-domain offsets.

[0184] When the first offset and the second offset are time-domain offsets, the first reference point and the second reference point are the same. The first reference point or the second reference point can be collectively referred to as the common reference point. That is, one of the at least one first offsets is the offset of the first LO relative to the common reference point, and one of the at least one second offsets is the offset of the first PO relative to the common reference point. More specifically, one of the at least one first offsets can be the offset of the start time of the first LO relative to the common reference point, and one of the at least one second offsets can be the offset of the start time of the first PO relative to the common reference point; or, one of the at least one second offsets can be the offset of the end time of the first LO relative to the common reference point, and one of the at least one second offsets can be the offset of the end time of the first PO relative to the common reference point.

[0185] The common reference point can be a synchronization signal or a reference signal, such as SSB, LP-SS, low-power TRS, low-power CSI-RS, or low-power DMRS.

[0186] Taking LP-SS as the common reference point as an example, Figure 8 A schematic diagram of the time-domain offset of LO and PO relative to LP-SS is shown. For example... Figure 8 As shown, the at least one LO includes LO 1, LO 2, and LO 3, and the at least one PO includes PO 1, PO 2, and PO 3. The time-domain offset of the start time of LO 1 relative to the end time of LP-SS includes N1 time-domain units, the time-domain offset of the start time of PO 1 relative to the end time of LP-SS includes N1' time-domain units, the time-domain offset of the start time of LO 2 relative to the end time of LP-SS includes N2 time-domain units, the time-domain offset of the start time of PO 2 relative to the end time of LP-SS includes N2' time-domain units, the time-domain offset of the start time of LO 3 relative to the end time of LP-SS includes N3' time-domain units.

[0187] exist Figure 8 In the example, the at least one first offset includes N1, N2, and N3, and the at least one second offset includes N1', N2', and N3'.

[0188] It should be noted that, Figure 8 The example described uses the end time of LP-SS as a common reference point. However, the common reference point can also be the start time of LP-SS, and this application does not limit this.

[0189] When the first offset and the second offset are frequency domain offsets, the first reference point and the second reference point are different. The first reference point is the reference point for the Loop Receiver (LO), and the second reference point is the reference point for the Point of Receiver (PO). For example, the first reference point is the center frequency of the SSB (Segment Sub-Band) in the frequency band to which the LO belongs, and the second reference point is the center frequency of the SSB in the frequency band to which the PO belongs. It should be noted that since the wake-up signal and paging message are deployed in different frequency bands, and synchronization cannot be performed simultaneously on different frequency bands, each frequency band has its own SSB.

[0190] Taking the first reference point as the center frequency of the SSB in the frequency band to which the LO belongs, and the second reference point as the center frequency of the SSB in the frequency band to which the PO belongs, as an example... Figure 9 A schematic diagram of the frequency domain offset of LO and PO relative to SSB is shown.

[0191] like Figure 9 As shown, the at least one LO includes LO 1, LO 2 and LO 3, the at least one PO includes PO 1, PO 2 and PO 3, the SSB of the frequency band to which the LO belongs is the first SBB, the SSB of the frequency band to which the PO belongs is the second SBB, the at least one first offset includes the offset N1 of LO 1 relative to the center frequency of the first SBB, the offset N2 of LO 2 relative to the center frequency of the first SBB, and the offset N3 of LO 3 relative to the center frequency of the first SBB, the at least one second offset includes the offset N1' of PO 1 relative to the center frequency of the second SBB, the offset N2' of PO 2 relative to the center frequency of the second SBB, and the offset N3' of PO 3 relative to the center frequency of the second SBB.

[0192] It should be noted that since the period of a reference point (e.g., SSB) is usually long, the first configuration information may include at least one time-domain offset of a LO relative to a common reference point, and at least one time-domain offset of a PO relative to a common reference point.

[0193] The at least one LO can be located within at least one DRX cycle of the wake-up signal, and the at least one PO can be located within at least one DRX cycle of the paging message. The DRX cycle of the wake-up signal can be understood as the DRX cycle used to transmit the wake-up signal, or in other words, the wake-up signal can be transmitted within this DRX cycle. Similarly, the DRX cycle of the paging message can be understood as the DRX cycle used to transmit the paging message, or in other words, the paging message can be transmitted within this DRX cycle.

[0194] In one possible scenario, the at least one LO is located within one DRX cycle of a wake-up signal, and the at least one PO is located within one DRX cycle of a paging message. This allows for the configuration of the correspondence between at least one LO within one DRX cycle of a wake-up signal and at least one PO within one DRX cycle of a paging message, which helps to save signaling overhead.

[0195] In another possible scenario, the at least one LO is located within multiple DRX cycles of the wake-up signal, and the at least one PO is located within multiple DRX cycles of the paging message. This considers the case where the at least one LO spans multiple DRX cycles, and the at least one PO also spans multiple DRX cycles; that is, the at least one LO is located within different DRX cycles of the wake-up signal, and the at least one PO is located within different DRX cycles. Similarly, the at least one PO is located within different DRX cycles. This allows for configuring the correspondence between at least one LO and at least one PO within more DRX cycles at once, which helps save overhead.

[0196] For example, the at least one LO includes LO 1, LO 2, LO 3 and LO 4, and the at least one PO includes PO 1, PO 2, PO 3 and PO 4, wherein LO 1 and LO 2 are located within DRX period 1 of the wake-up signal, LO 3 and LO 4 are located within DRX period 2 of the wake-up signal, PO 1 is located within DRX period 1 of the wake-up signal, PO 2 is located within DRX period 2 of the wake-up signal, PO 3 is located within DRX period 3 of the wake-up signal, and PO 4 is located within DRX period 5 of the wake-up signal.

[0197] Furthermore, the DRX period of the wake-up signal may differ from that of the paging message. Therefore, the number of Locators (LOs) within a single wake-up signal's DRX period may differ from the number of Points of Interest (POs) within a single paging message's DRX period. Consequently, it's possible for one LO to correspond to multiple POs, or vice versa. For example, if the wake-up signal's DRX period is longer and the paging message's DRX period is shorter, the at least one LO may be located within one wake-up signal's DRX period, while the at least one PO may be located within multiple paging message DRX periods. Conversely, if the wake-up signal's DRX period is shorter and the paging message's DRX period is longer, the at least one LO may be located within multiple wake-up signal DRX periods, while the at least one PO may be located within one paging message's DRX period.

[0198] Similar to Implementation Method 1 described above, the correspondence between the first subcarrier interval and the first configuration information in Implementation Method 2 can be shown in the form of a configuration table, such as Table 2. Table 2 shows the (time domain / frequency domain) offset of each LO in at least one LO relative to the first reference point under different subcarrier intervals. Similarly, Table 3 shows the (time domain / frequency domain) offset of each PO in at least one PO relative to the second reference point under different subcarrier intervals.

[0199] Taking the combination of WUR subcarrier spacing of 30kHz and MR subcarrier spacing of 15kHz in Table 2 as an example, the corresponding first offset set is {2,4,6,8,10}. The first offset set includes five first offsets, which correspond one-to-one with the five LOs. That is, the first offset is the offset of the first LO relative to the first reference point in the (time domain / frequency domain).

[0200] Taking the combination of WUR with a subcarrier spacing of 30kHz and MR with a subcarrier spacing of 15kHz in Table 3 as an example, the corresponding second offset set is {12,14,16,18,20}. The second offset set includes five second offsets, which correspond one-to-one with the five POs. That is, the second offset is the (time domain / frequency domain) offset of the first PO relative to the second reference point.

[0201] It is understandable that the time domain offset includes N time domain units, which can be granularized as radio frames, subframes, time slots, mini-time slots, OFDM symbols, etc. Or, the frequency domain offset includes N frequency domain units, which can be granularized as RE, PRB, subcarrier, or RBG.

[0202] In one possible implementation, the network device may send a first indication information to the terminal device, which indicates the offset of the LO corresponding to Table 2 relative to the first reference point and the offset of the PO corresponding to Table 3 relative to the second reference point.

[0203] In another possible implementation, Table 2 corresponds to the first field, and Table 3 corresponds to the second field. That is, the first field is used to indicate that Table 2 shows the offset of LO relative to the first reference point, and the second field is used to indicate that Table 3 shows the offset of PO relative to the second reference point.

[0204] Table 2

[0205]

[0206] Table 3

[0207]

[0208] In one possible implementation, the at least one first offset corresponds to the at least one second offset in sequence.

[0209] In one scenario, the correspondence between the at least one first offset and the at least one second offset can be one-to-one, wherein the at least one first offset is arranged in ascending order, and the at least one second offset is arranged in ascending order. Based on the correspondence between the at least one first offset and the at least one second offset, the correspondence between the at least one LO and the at least one PO can be determined.

[0210] Referring to Tables 2 and 3, taking the combination of a 30kHz subcarrier spacing for WUR and a 15kHz subcarrier spacing for MR as an example, if at least one first offset corresponds sequentially to at least one second offset, then the LO with a first offset of 2 corresponds to the PO with a second offset of 12; the LO with a time-domain offset of 4 time-domain units relative to the common reference point corresponds to the PO with a time-domain offset of 14 time-domain units relative to the common reference point, and so on. This allows us to determine the correspondence between at least one LO and at least one PO. The unit of offset is either a time-domain unit or a frequency-domain unit.

[0211] In another scenario, the first offset corresponds to multiple second offsets, meaning one LO can correspond to multiple POs; or, the second offset corresponds to multiple first offsets, meaning one PO can correspond to multiple LOs.

[0212] As shown in Table 4, taking the combination of a WUR subcarrier spacing of 30kHz and an MR subcarrier spacing of 15kHz as an example, the corresponding first offset set is {2}. The first offset set includes a first offset with a value of 2, which is the (time domain / frequency domain) offset of LO 1 relative to the first reference point. The unit of the offset is a time domain cell or a frequency domain cell.

[0213] Table 4

[0214]

[0215] As shown in Table 5, for the combination of WUR subcarrier spacing of 30kHz and MR subcarrier spacing of 15kHz, the corresponding second offset set is {8,10,12}. The second offset set includes three second offsets, where the second offset with a value of 8 is the (time domain / frequency domain) offset of PO1 relative to the second reference point, the second offset with a value of 10 is the (time domain / frequency domain) offset of PO2 relative to the second reference point, and the second offset with a value of 12 is the (time domain / frequency domain) offset of PO3 relative to the second reference point. In this context, the first offset in the first offset set corresponds to three second offsets in the second offset set. Since this first offset corresponds to LO 1, and these three second offsets correspond to PO 1, PO 2, and PO 3, LO 1 corresponds to PO 1, PO 2, and PO 3. That is, the terminal device monitors the wake-up signal on LO 1. If the wake-up signal indicates that PDCCH monitoring is required, the terminal device monitors the PDCCH on PO 1, PO 2, and PO 3 corresponding to LO 1 to obtain the paging message. The unit of the offset is a time-domain unit or a frequency-domain unit.

[0216] It is understandable that time-domain units can be granular, such as radio frames, subframes, time slots, mini-time slots, OFDM symbols, etc., while frequency-domain units can be granular, such as REs, subcarriers, PRBs, RBGs, etc.

[0217] Table 5

[0218]

[0219] Understandably, Tables 4 and 5 show the case where one LO corresponds to multiple POs, and the case where one PO corresponds to multiple LOs is similar to the indication method in Tables 5 and 6, so it will not be repeated here.

[0220] In one possible implementation, the network device may send a second indication information to the terminal device, which indicates the offset of the LO corresponding to Table 4 relative to the first reference point and the offset of the PO corresponding to Table 5 relative to the second reference point.

[0221] In another possible implementation, Table 4 corresponds to the third field, and Table 5 corresponds to the fourth field. The third field is used to indicate that Table 4 shows the offset of LO relative to the first reference point, and the fourth field is used to indicate that Table 5 shows the offset of PO relative to the second reference point.

[0222] In the third implementation method, the first configuration information includes multiple offsets. These multiple offsets include the offset of the at least one PO relative to the second LO, or the offset of the at least one LO relative to the second PO, where the second LO is one of the at least one LO and the second PO is one of the at least one PO. In other words, these multiple offsets can indicate multiple POs corresponding to one LO, or multiple LOs corresponding to one PO.

[0223] It should be noted that in this implementation, the offset in the first configuration information is a time-domain offset.

[0224] It should be noted that since the cycles of LO and PO may be different, or the number of resources may be different, it is possible to map one LO to multiple PO, or one PO to multiple LO.

[0225] Similar to the first implementation method described above, the correspondence between the first subcarrier interval and the first configuration information can be predefined by the protocol, indicated by the network device, or dynamically configured by the network device.

[0226] For example Figure 10A As shown, the at least one LO includes LO 1, the at least one PO includes PO 1, PO 2 and PO 3, and the multiple offsets in the first configuration information may include the offset N1 of PO 1 relative to LO 1, the offset N2 of PO 2 relative to LO 1, and the offset N3 of PO 3 relative to LO 1.

[0227] Understandable Figure 10A Taking at least one LO as an example, the number of at least one LO can also be multiple, and each of the multiple LOs can correspond to one or more POs.

[0228] Understandable Figure 10A The following example illustrates the offsets between the start times of PO1, PO2, and PO3 and the start time of LO1. Furthermore, the offsets of PO1, PO2, and PO3 relative to LO1 can also be the offsets between the start times of PO1, PO2, and PO3 and the end times of LO1, or the offsets between the end times of PO1, PO2, and PO3 and the start times of LO1, or the offsets between the end times of PO1, PO2, and PO3 and the end times of LO1.

[0229] For example Figure 10BAs shown, the at least one LO includes LO 1, LO 2 and LO 3, the at least one PO includes PO 1, and the multiple offsets in the first configuration information may include the offset N1 of LO 1 relative to PO 1, the offset N2 of LO 2 relative to PO 1, and the offset N3 of LO 3 relative to PO 1.

[0230] Understandable Figure 10B Taking at least one PO as an example, the number of at least one PO can also be multiple, and each of the multiple POs can correspond to one or more LOs.

[0231] Understandable Figure 10B The following example illustrates the offsets between the start times of LO1, LO2, and LO3 and the start time of PO1. Furthermore, the offsets of LO1, LO2, and LO3 relative to PO1 can also be the offsets between the start times of LO1, LO2, and LO3 and the end times of PO1, or the offsets between the end times of LO1, LO2, and LO3 and the start times of PO1, or the offsets between the end times of LO1, LO2, and LO3 and the end times of PO1.

[0232] Similar to implementation method one described above, the correspondence between the first subcarrier interval and the first configuration information in implementation method three can be shown in the form of a configuration table, such as Table 6. The time-domain offset can be the offset of at least one PO relative to one LO, or the offset of at least one LO relative to one PO. The unit of the offset is a time-domain unit.

[0233] It is understandable that time-domain units can be granular, such as radio frames, subframes, time slots, mini-time slots, OFDM symbols, etc.

[0234] Table 6

[0235] WUR subcarrier spacing Subcarrier spacing of MR Time domain offset N 15kHz 15kHz 6,8,10 30kHz 15kHz 8,10,12 15kHz 30kHz 10,12,14 … … …

[0236] Taking the combination of a WUR subcarrier spacing of 30kHz and an MR subcarrier spacing of 15kHz as an example, the corresponding time-domain offset set is {8,10,12}, which includes three time-domain offsets that can indicate three POs (e.g., PO1, PO2, and PO3) corresponding to one LO (e.g., LO1). Among them, the time-domain offset of PO1 relative to LO1 includes 8 time-domain units, the time-domain offset of PO2 relative to LO1 includes 10 time-domain units, and the time-domain offset of PO3 relative to LO1 includes 12 time-domain units. Alternatively, the time-domain offset set {8, 10, 12} corresponding to the combination of a WUR subcarrier spacing of 30 kHz and an MR subcarrier spacing of 15 kHz can indicate three LOs (e.g., LO 1, LO 2, and LO 3) corresponding to a PO (e.g., PO 1), wherein the time-domain offset of LO 1 relative to PO 1 includes 8 time-domain units, the time-domain offset of LO 2 relative to PO 1 includes 10 time-domain units, and the time-domain offset of LO 3 relative to PO 1 includes 12 time-domain units.

[0237] In one possible implementation, the network device may send a third indication information to the terminal device, which indicates that Table 6 corresponds to the offset of LO relative to PO, or the offset of PO relative to LO.

[0238] In another possible implementation, Table 6 corresponds to the fifth field, which indicates whether Table 6 shows the offset of LO relative to the first reference point or the offset of PO relative to the second reference point.

[0239] Implementation Method Four: The first configuration information includes one or more of the following: the offset of the first monitoring time relative to the third reference point in at least one monitoring time; the offset between adjacent monitoring times in at least one monitoring time; or, the number of at least one monitoring time. Wherein, the first monitoring time is one of the at least one monitoring time. The at least one monitoring time is the at least one LO, and the third reference point is the same as the first reference point mentioned above; or, the at least one monitoring time is the at least one PO, and the third reference point is the same as the second reference point mentioned above.

[0240] The first monitoring time point is, for example, the monitoring time point with the earliest start time among the at least one monitoring time point, or the first monitoring time point is, for example, the monitoring time point with the latest start time among the at least one monitoring time point.

[0241] For a description of the first and second reference points, please refer to the above text; they will not be repeated here.

[0242] Taking the monitoring timing as LO as an example, please refer to... Figure 8The at least one LO (i.e., the at least one monitoring moment) includes LO1, LO2, and LO3. Assuming that the first LO (i.e., the first monitoring moment) is the LO with the earliest start time among LO1, LO2, and LO3, i.e., LO1, the terminal device can determine the position of each LO among the at least one LO if it knows the offset of LO1 relative to LP-SS, the offset between adjacent LOs (including the offset between LO1 and LO2, and the offset between LO2 and LO3), and the number of the at least one LO.

[0243] It is understandable that the offsets between adjacent LOs in at least one LO can be the same or different. For example... Figure 8 In the diagram, let the offset between LO 1 and LO 2 be offset #1, and the offset between LO 2 and LO 3 be offset #2. Offset #1 and offset #2 can be the same or different.

[0244] Similarly, taking the monitoring timing as PO as an example, see [link / reference]. Figure 8 The at least one PO (i.e., the at least one monitoring moment) includes PO 1, PO 2 and PO 3. Assuming that the first PO (i.e. the first monitoring moment) is the PO with the earliest start time among PO 1, PO 2 and PO 3, i.e. PO 1, the terminal device can determine the position of each of the at least one PO if it knows the offset of PO 1 relative to LP-SS, the offset between adjacent POs (including the offset between PO 1 and PO 2, and the offset between PO 2 and PO 3), and the number of the at least one PO.

[0245] It is understandable that the offsets between adjacent POs in at least one PO can be the same or different. For example... Figure 8 In the diagram, let the offset between PO1 and PO2 be offset #3, and the offset between PO2 and PO3 be offset #4. Offset #3 and offset #4 can be the same or different.

[0246] In this implementation, the terminal device can determine the at least one LO or the at least one PO based on the first configuration information. The specific determination process can be found in the description of S602 below, and will not be detailed here.

[0247] As can be seen from the tables in the examples above, as the subcarrier spacing of the WUR or MR increases, the configuration offset also increases. This allows for more processing time between the LO and PO, preventing missed paging messages. Conversely, as the subcarrier spacing of the WUR or MR decreases, the configuration offset also decreases, avoiding time redundancy and reducing system latency.

[0248] S602, based on the first configuration information, determine the at least one LO and / or the at least one PO.

[0249] It is understandable that the above S602 can be executed by the terminal device.

[0250] For implementation method one or three described above, the network device can pre-configure the at least one LO, for example, through RRC messages, system messages, or dynamic configuration. In this way, the terminal device can determine the at least one PO based on the first configuration information corresponding to the first subcarrier interval. For example, the first configuration information includes a time-domain offset, which is the time-domain offset of the first PO relative to the first LO. Then, the terminal device can determine the first PO based on the pre-configured first LO and the time-domain offset of the first PO relative to the first LO.

[0251] Similarly, network devices can pre-configure the at least one PO, for example, through RRC messages, system messages, or dynamic configuration. In this way, the terminal device can determine the at least one LO based on the first configuration information corresponding to the first subcarrier interval. For example, if the first configuration information includes a time-domain offset, which is the time-domain offset of the first LO relative to the first PO, then the terminal device can determine the first LO based on the pre-configured first PO and the time-domain offset of the first LO relative to the first PO.

[0252] In the second implementation described above, the terminal device can determine the at least one LO and the at least one PO based on the first configuration information. Alternatively, the network device can pre-configure the at least one LO, and the terminal device can determine each of the at least one POs based on the offset of each PO relative to the second reference point indicated in the first configuration information. Alternatively, the network device can pre-configure the at least one PO, and the terminal device can determine each of the at least one LOs based on the offset of each LO relative to the first reference point indicated in the first configuration information.

[0253] For the above implementation method four, the terminal device can determine the at least one LO and the at least one PO based on the first configuration information. Referring to the description of implementation method four above, assuming that the first monitoring time is the earliest starting time among the at least one monitoring time, the offset of the first monitoring time relative to the third reference point is a, the offset between adjacent monitoring times is d, and the number of the at least one monitoring time is M, then the position P of the i-th monitoring time among the at least one monitoring time is... i Satisfies the following formula: P i = a + (i-1) × d, i = 1, 2, ..., M. Wherein, the at least one monitoring time is the at least one LO, and the first monitoring time is, for example, the LO with the earliest start time among the at least one LO; or, the at least one monitoring time is the at least one PO, and the first monitoring time is, for example, the PO with the earliest start time among the at least one PO.

[0254] In the case where the first configuration information is network device configuration, one possible implementation is that in S601, the terminal device obtains the first configuration information corresponding to the first subcarrier interval by receiving a first message, which includes the first configuration information corresponding to the first subcarrier interval. The first message can be an RRC message, a system message, or a MACCE. Alternatively, the first message can be a wake-up signal.

[0255] In one possible implementation, after S602, method 600 further includes S603: the network device sends a wake-up signal on the fourth LO, and correspondingly, the terminal device monitors the wake-up signal on the fourth LO. If the wake-up signal indicates that PDCCH monitoring is required, then method 600 further includes S604: the network device sends a paging message on the PO corresponding to the fourth LO, and correspondingly, the terminal device monitors the paging message on the PO corresponding to the fourth LO. The wake-up signal and the paging message correspond to different frequency bands, and the wake-up signal is, for example, the first message mentioned above. The fourth LO can be any one of the at least one LO. The fourth LO can correspond to one or more POs.

[0256] In one possible implementation, prior to S601, the terminal device can determine whether the subcarrier spacing of the WUR is the same as that of the MR. If the subcarrier spacing of the WUR is different from that of the MR, the terminal device can obtain first configuration information corresponding to the first subcarrier spacing, determine the correspondence between the at least one LO and the at least one PO, and thus determine the at least one LO and / or the at least one PO. If the subcarrier spacing of the WUR is the same as that of the MR, the terminal device can receive configuration information of the PO from the network device according to the configuration method in the existing scheme, and then receive first information from the network device, the first information being used to indicate the offset of the LO relative to the PO in the time domain and / or frequency domain. In the existing scheme, the offset between the LO and the PO is independent of the subcarrier spacing.

[0257] For network devices, before sending the first message, the network device can determine whether the subcarrier spacing of the WUR is the same as the subcarrier spacing of the MR. If the subcarrier spacing of the WUR is different from that of the MR, the network device can determine the first configuration information corresponding to the first subcarrier spacing and send the first message to the terminal device. If the subcarrier spacing of the WUR is the same as that of the MR, the network device can send the configuration information of the PO to the terminal device, and then send the first message to the terminal device.

[0258] In the above description, the offset in the time domain and the offset in the frequency domain can be configured independently or jointly to determine the LO and / or PO. For example, for the combination of a WUR subcarrier spacing of 30kHz and an MR subcarrier spacing of 15kHz, the corresponding offset includes a time-frequency resource group (F, T), where F is the offset in the frequency domain and T is the offset in the time domain. The specific method for determining the offset can be found in the above description and will not be repeated here.

[0259] Figure 11 A schematic diagram of a paging process 1100 based on a wake-up signal is shown, wherein the wake-up signal and the paging message come from the same network device, for example, from the same base station or from the same TRP.

[0260] Paging procedure 1100 includes steps S1101 to S1106, and the specific steps are as follows:

[0261] S1101, when the terminal device is in RRC connection state, the network device sends an RRC message to the terminal device. Optionally, the RRC message carries first configuration information, which is used to indicate the correspondence between at least one LO and at least one PO.

[0262] S1102, the network device sends an RRC release signaling message to the terminal device. Correspondingly, the terminal device receives the RRC release signaling message, releases the RRC connection with the network device, and enters the RRC inactive state or RRC idle state.

[0263] In one possible scenario, if the network device determines that there is no service transmission at present, the network device can send an RRC release signaling to the terminal device in order to reduce the power consumption of the terminal device.

[0264] S1103, the network device sends a synchronization signal.

[0265] S1104, the network device sends system messages, such as SIB 1 or OSI.

[0266] Optionally, the system message carries first configuration information.

[0267] S1105, the network device sends a wake-up signal to the terminal device, and the terminal device monitors the wake-up signal based on the first configuration information.

[0268] Optionally, the wake-up signal carries first configuration information. In one possible scenario, if there is subsequent service transmission, the network device indicates the need to monitor the PDCCH through the wake-up signal, or in other words, the network device triggers the monitoring of paging messages through the wake-up signal.

[0269] S1106, the network device sends a paging message to the terminal device, and correspondingly, the terminal device monitors the paging message based on the first configuration information.

[0270] The above method 600 can be implemented in conjunction with paging procedure 1100, or as a part of the paging procedure 1100. For example, in paging procedure 1100, the terminal device receives the first configuration information through network-side signaling, which corresponds to the first configuration information obtained by the terminal device in method 600 for the first subcarrier interval. As another example, in paging procedure 1105, the terminal device monitors the wake-up signal based on the first configuration information, which may include the above-described S602, i.e., the terminal device determines at least one LO and / or at least one PO based on the first configuration information, and then the terminal device monitors the paging signal on the determined LO. Similarly, in paging procedure 1106, the terminal device monitors the paging message based on the first configuration information, which may include the above-described S602, i.e., the terminal device determines at least one LO and / or at least one PO based on the first configuration information, and then the terminal device monitors the paging message on the determined PO.

[0271] Figure 12A schematic diagram of another paging process 1200 based on a wake-up signal is shown, in which the wake-up signal and the paging message originate from different devices, such as different base stations, different TRPs, or different terminal devices. Taking the wake-up signal and paging message originating from different TRPs as an example, the TRP used to send the wake-up signal is called TRP 1, also known as WUR-TRP, and the TRP used to send the paging message is called TRP 2, also known as MR-TRP. TRP 1 and TRP 2 can be different TRPs of the same base station or different TRPs of different base stations. When the terminal device has established an RRC connection with TRP 2, TRP 1 and TRP 2 can configure the correspondence between at least one LO and at least one PO.

[0272] Paging procedure 1200 includes steps S1201 to S1208, and the specific steps are as follows:

[0273] S1201, when the terminal device is in an RRC connection, TRP 1 sends an RRC message to the terminal device. Optionally, the RRC message carries first configuration information, which is used to indicate the correspondence between the at least one LO and the at least one PO.

[0274] S1202, when the terminal device is in an RRC connection, TRP 2 sends an RRC message to the terminal device. Optionally, the RRC message carries first configuration information, which is used to indicate the correspondence between the at least one LO and the at least one PO.

[0275] In this configuration, the correspondence between the at least one LO and the at least one PO sent to the terminal device by TRP 1 and TRP 2 is identical. The terminal device may choose to receive the first configuration information from TRP 1 or from TRP 2.

[0276] S1203, the network device sends an RRC release signaling message to the terminal device. Accordingly, the terminal device receives the RRC release signaling message, releases the RRC connection with the network device, and enters the RRC inactive state or RRC idle state.

[0277] In one possible scenario, if the network device determines that there is no service transmission at present, the network device can send an RRC release signaling to the terminal device in order to reduce the power consumption of the terminal device.

[0278] Among them, the RRC non-connected state refers to the non-connected state of MR, in which case WUR may remain in the RRC connected state.

[0279] S1204, TRP 1 sends a synchronization signal.

[0280] S1205, TRP 2 sends a synchronization signal.

[0281] In one possible scenario, during the DRX cycle, TRP 1 and TRP 2 may broadcast synchronization signals, and the terminal device may receive these synchronization signals for synchronization. Since TRP 1 operates in a low-frequency band while TRP 2 operates in a high-frequency band, the synchronization signals transmitted by TRP 1 and TRP 2 are different, allowing the terminal device to synchronize based on each signal separately.

[0282] S1206, TRP 1 sends system messages, such as SIB 1 or OSI.

[0283] Optionally, the system message carries first configuration information. The terminal device can receive system messages on demand.

[0284] S1207, TRP 1 sends a wake-up signal to the terminal device, and correspondingly, the terminal device monitors the wake-up signal based on the first configuration information.

[0285] Optionally, the wake-up signal carries first configuration information. In one possible scenario, if there is subsequent service transmission, the network device indicates the need to monitor the PDCCH through the wake-up signal, or in other words, the network device triggers the monitoring of paging messages through the wake-up signal.

[0286] S1208, TRP 2 sends a paging message to the terminal device, and correspondingly, the terminal device monitors the paging message based on the first configuration information.

[0287] TRP 1 and TRP 2 can negotiate, with TRP 1 sending a wake-up signal and TRP 2 sending a paging message.

[0288] The above method 600 can be implemented in conjunction with paging procedure 1200, or as a part of the paging procedure 1200. For example, in paging procedure 1200, the terminal device receives the first configuration information through network-side signaling, which corresponds to the first configuration information obtained by the terminal device in method 600 for the first subcarrier interval. As another example, in paging procedure 1207, the terminal device monitors the wake-up signal based on the first configuration information, which may include the above-mentioned S602, that is, the terminal device determines at least one LO and / or at least one PO based on the first configuration information, and then the terminal device monitors the paging signal on the determined LO. Similarly, in paging procedure 1208, the terminal device monitors the paging message based on the first configuration information, which may include the above-mentioned S602, that is, the terminal device determines at least one LO and / or at least one PO based on the first configuration information, and then the terminal device monitors the paging message on the determined PO.
