Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication, and in particular, to an information receiving method, an information sending method and a communication apparatus. BACKGROUND

[0002] In a wireless communication system, a network device (such as a core network or a base station) can notify a terminal device of arrival of a service through a paging message. Correspondingly, the terminal device determines whether the paging message is related to itself by receiving the paging message, so as to subsequently process the service. Specifically, the terminal device can first detect a downlink control information (DCI), which indicates a radio resource carrying the paging message, a modulation and coding scheme used, and the like. Then, the terminal device receives the paging message according to the detected DCI, and determines whether the paging message is related to itself according to the content of the paging message, such as whether there is an identifier of the terminal device, whether there is an identifier of a service of interest of the terminal device, and the like. If it is determined that the paging message is related to itself, the terminal device processes the subsequent service according to the paging message.

[0003] When the network device notifies the terminal device of arrival of a Multicast / Broadcast Service (MBS), a mechanism similar to the above paging mechanism can also be used. Specifically, for example, an MBS indication can be added to the above DCI, or an identifier related to the MBS, such as a temporary mobile group identity (TMGI), can be added to the above paging message.

[0004] However, even if the paging message only pages the MBS, the terminal device not interested in the MBS still needs to read the above DCI to determine that the paging is not related to itself through the MBS indication in the DCI, or even needs to read the DCI and the paging message, and then determine that the paging is not related to itself according to the identifier in the paging message.

[0005] Therefore, the above paging mechanism increases the power consumption of the terminal device not interested in the MBS, thereby affecting the endurance of the terminal device. SUMMARY

For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c".

[0086] Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be capable of explicit and implicit combinations, and each of the various embodiments appearing herein can be referenced or explained in connection with one another, without limitation.

[0087] The method and communication device provided by the embodiments of the present application can be applied to various communication systems, for example: a 4th generation (4G) communication system, a 4.5G communication system, a 5G communication system, a system integrating multiple communication systems, or a future evolved communication system (for example, a 6G communication system). For example, a long term evolution (LTE) system, a new radio (NR) system, a wireless-fidelity (WiFi) system, a wireless self-organizing system, a device-to-device direct communication system, a 3rd generation partnership project (3GPP) related communication system, and other communication systems.

[0088] Before introducing the method of the present application, first, introduce the terms related to the embodiments of the present application.

[0089] I. Service state

[0090] The service state in the embodiments of the present application can include the following types:

[0091] 1. Unicast service state, which can specifically refer to that the terminal device only supports unicast service, or the terminal device is only interested in unicast service, or only receives unicast service. In other words, the service state can refer to that the terminal device has no MBS capability, is not interested in MBS, or does not receive MBS.

[0092] 2. Multicast service state, which can specifically refer to that the terminal device supports multicast service, or the terminal device is interested in multicast service, or is receiving multicast service.

[0093] 3. Broadcast service state, which can specifically refer to that the terminal device supports broadcast service, or the terminal device is interested in broadcast service, or is receiving broadcast service.

[0094] II. Paging

[0095] The terminal device wakes up from the sleep state at a paging occasion (PO) in each paging cycle, detects whether there is a paging message, and performs service processing according to the received paging message. Specifically, the terminal device can first detect a downlink control information (DCI) indicating a radio resource carrying a paging message, and information such as a modulation and coding mechanism used, and then the terminal device receives the paging message according to the detected DCI, and according to the content in the paging message, confirms whether the paging message is related to itself, such as whether there is its own identifier information, whether there is identifier information of a service of interest, and the like. If it is determined that the paging message is related to itself, subsequent service processing is performed according to the paging message.

[0096] III. Wake up signal (WUS)

[0097] The wake up signal in the embodiments of the present application is designed for energy saving of the terminal device. The wake up signal can also be referred to as an energy saving signal, or WUS. In order to further save power of the terminal device, a wake up signal can be detected before the DCI is detected at the paging occasion. If the wake up signal is detected, the terminal device further detects the DCI and the paging message; if the wake up signal is not detected, the terminal device does not further detect the DCI, and continues to sleep in the paging cycle, and then detects the wake up signal before the DCI is detected at the PO in the next paging cycle, and performs corresponding actions according to whether the wake up signal is detected.

[0098] Compared with directly detecting the DCI or directly detecting the paging message, the UE detects the wake up signal first, which has lower energy consumption. The wake up signal in the embodiments of the present application can be applied to energy saving in the process of receiving a paging message, can be applied to energy saving in the process of receiving a system broadcast message, can be applied to energy saving in the process of receiving a Multicast Control Channel (MCCH), and the like.

[0106] Figure 2 is a schematic block diagram of the communication apparatus 1000 provided by the embodiments of the present application. As shown in Figure 2 the communication apparatus 1000 can include a transceiver unit 1100 and a processing unit 1200.

[0107] The communication apparatus 1000 can be a network device 110 or an apparatus applied in the network device 110. Alternatively, the communication apparatus 1000 can be a terminal device 111 or 112, or an apparatus applied in the terminal device 111 or 112.

[0108] The processing unit 1100 can process the received signal or information, or process the signal or information before transmitting the signal or information. For example, when the processing unit 1100 belongs to the network device 110, the processing unit 1100 can perform baseband processing on the signal or information received by the transceiver unit 1200. Alternatively, the baseband-processed information is further processed, for example, when the information received by the transceiver unit 1200 is a radio resource control (RRC) connection request message from the terminal device, the processing unit 1100 of the network device 110 can perform access control, for example, according to system load and / or priority information of the terminal device, to determine whether to allow the terminal device to access. For another example, when the processing unit 1100 belongs to the terminal device 111 or 112, the processing unit 1100 can perform baseband processing on the signal or information received by the transceiver unit 1200. For example, the processing unit 1100 determines to further detect the DCI corresponding to the wake-up signal after the transceiver unit 1200 receives the wake-up signal, and determines whether there is a paging message related to itself after the transceiver unit 1200 receives the paging message.

[0109] The transceiver unit 1200 can perform signal reception and / or transmission. For example, when the transceiver unit 1200 belongs to the network device 110, the transceiver unit 1200 can transmit signals or information to the terminal device 111 or 112, wherein the signals or information can include WUS, DCI, paging message, system broadcast message, MCCH, downlink data, etc. Correspondingly, when the transceiver unit 1200 belongs to the terminal device 111 or 112, the transceiver unit 1200 can receive the above-mentioned signals or information from the network device 110. For another example, when the transceiver unit 1200 belongs to the network device 110, the transceiver unit 1200 can receive signals or information from the terminal device 111 or 112, wherein the signals or information can include measurement report, uplink data, uplink reference signal, reception status information of downlink data, etc. Correspondingly, when the transceiver unit 1200 belongs to the terminal device 111 or 112, the transceiver unit 1200 can transmit the above-mentioned signals or information to the network device 110.

[0110] The communication device 1000 may further include a communication unit 1300. This communication unit 1300 can receive and / or transmit signals or information with other network devices. For example, when the communication unit 1300 belongs to network device 110, when the communication unit 1300 can communicate with other network devices (… Figure 1 (Not shown in the image). For example, if network device 110 is a base station and other network devices are also base stations, then communication unit 1300 can communicate with other base stations (receive and / or send signals or information). Or, if network device 110 is a base station and other network devices are the core network, then communication unit 1300 can communicate with the core network (receive and / or send signals or information).

Figure 3 As shown, the communication device 2000 may include one or more processors 2100. Figure 3 (Only one processor is shown in the image), and it may also include a transceiver 2200.

[0112] The communication device 2000 can be used as a network device 110 or as a device applied in a network device 110. Alternatively, the communication device 2000 can be used as a terminal device 111 or a terminal device 112, or as a device applied in a terminal device 111 or a terminal device 112.

[0113] Specifically, the functions of the processing unit 1100 in the communication device 1000 can be implemented by one or more processors 2100. The functions of the transceiver unit 1200 in the communication device 1000 can be implemented by a transceiver 2200.

Figure 3 In the examples given, the processor 2100, the transceiver 2200, and the memory 2300 are connected through a bus 2400, which is represented by a thick line, and the connection between other components is only illustrative and is not limited. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 3 only one thick line is used in the embodiments of this application, but it does not mean that there is only one bus or only one type of bus.

[0117] It can be understood that, in the embodiments of this application, Figure 3 when the communication apparatus is a network device, the network device can also have more components and the like than Figure 3 when the communication apparatus is a terminal device, the terminal device can also have more components and the like than Figure 3 the terminal device shown in the embodiments of this application. The embodiments of this application are not limited in this regard. Figure 4

[0118] Figure 4 is a schematic block diagram of a circuit system 3000 provided by the embodiments of this application. As Figure 5 shown, the network device can include a processing circuit 3100 and an interface circuit 3200.

[0119] The circuit system 3000 can be a network device 110 or a device applied in the network device 110. Alternatively, the circuit system 3000 can be a terminal device 111 or a terminal device 112, or a device applied in the terminal device 111 or the terminal device 112. At this time, the processing unit 1100 can be implemented by the processing circuit 3100, and the transceiving unit 1200 can be implemented by the interface circuit 3200. The processing circuit 3100 can be a chip, a logic circuit, an integrated circuit, or a system on chip (SoC) chip, and the interface circuit 3200 can be a communication interface, an input / output interface, etc.

[0120] In the embodiments of this application, the processor 2100 or the processing circuit 3100 can be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, etc., which can implement or execute the methods, steps, and logic block diagrams provided by the embodiments of this application. The general-purpose processor can be a microprocessor or any conventional processor, etc. The steps of the methods provided in conjunction with the embodiments of this application can be directly embodied as hardware processor execution, or executed by a combination of hardware and software modules in the processor, etc.

[0121] ​The following describes a method provided by an embodiment of the application in combination with the above communication device and system.

[0122] It should be understood that only the network device and / or the terminal device are taken as examples of the execution subject in the method embodiments described below, and the network device can also be replaced by a chip configured in the network device, and the terminal device can also be replaced by a chip configured in the terminal device.

[0123] Generally, the network device notifies the terminal device of the arrival of a service through a paging mechanism. Correspondingly, the terminal device determines whether there is information related to itself in the paging message by receiving the paging message, so as to subsequently process the service. In order to save power, the terminal device periodically wakes up to listen to the paging message from the network device in an idle state or an inactive state, and is in a sleep state (such as turning off the receiver) at other times. Specifically, the terminal device can wake up at a paging occasion (PO) in each paging cycle to detect (or receive) the DCI sent by the network device, and then receive the paging message according to the detected (or received) DCI, and determine whether the paging message is related to itself according to the content in the paging message. The terminal device can also read system information according to the indication of the short message in the DCI (for example, the terminal device reads the system information according to the indication of the short message if the system information is changed). In order to further save power, the terminal device will first detect a wake-up signal before waking up to listen to the DCI at each PO, and only after detecting the wake-up signal, will the terminal device further receive the DCI and the paging message. If the wake-up signal is not detected, the terminal device will not receive the DCI and the paging message in the current paging cycle.

[0124] Since the paging message is sent to a group of terminal devices (for example, the paging message can carry the identification information of multiple terminal devices, or carry the service identification information for a group of terminal devices), the paged terminal device knows whether the paging message is related to itself only after detecting and receiving the paging message. For example, the service state of the terminal device 1 is a unicast service state, but the paging message is for MBS, and then the terminal device 1 must first receive the paging message to know that the paging is not related to itself. At this time, the terminal device detects the DCI (or the wake-up signal and the DCI), and receives the paging message not related to itself, which wastes the power of the terminal device and affects the battery life.

[0125] In view of this, the embodiments of the application provide an information receiving method and a sending method, which reduce the power consumption caused by the terminal device detecting the paging message not related to itself, and are beneficial to the battery life.

[0126] The information receiving method and the sending method provided by the embodiments of the application are described by taking the terminal device 111 and the network device 110 as examples of the execution subject.

[0127] In the information receiving method and sending method provided by the embodiments of the present application, the terminal device 111 determines whether to detect a wake-up signal according to a service state. For example, when the service state is a unicast service state, the wake-up signal is detected; when the service state includes a multicast service state and / or a broadcast service state, the wake-up signal is not detected. Alternatively, the wake-up signal is refined, and the terminal device detects different wake-up signals in different service states. In this way, the power consumption caused by the terminal device waking up to detect and receive service notification information irrelevant to itself can be reduced.

[0128] Figure 5 FIG. 1 is a flowchart of an information receiving method and sending method provided by the embodiments of the present application. As shown in FIG. 1, the method includes the following steps. Figure 6

[0129] S101a, the network device 110 determines a service type to be notified.

[0130] The service type to be notified refers to which service is to be notified, which service is to be received by the terminal device, or which service has data to be transmitted by the terminal device, etc.

[0131] For example, the service type to be notified can include at least one of a unicast service, a multicast service, and a broadcast service. Alternatively, the service type to be notified can include at least one of a unicast service and an MBS (i.e., without distinguishing between a multicast service and a broadcast service).

[0132] ​The manner in which the network device obtains the service type to be notified can include receiving a service notification information from the core network first, which can be a paging or other information of the core network, and the embodiments of the present application are not limited. For example, when the core network has a notification of a related MBS service, such as the start of the MBS, the transmission of MBS data, etc., the core network triggers the notification, and accordingly, the service notification information can indicate one or more of the information related to the multicast service and / or the broadcast service, such as the service identity (Service ID), TMGI, MBS Indicator, service type (such as multicast service, broadcast service), and the identification information of the terminal device receiving the service or interested in the service (such as UE ID). For another example, the network device can request the content of the service notification information from the core network, and then receive a service notification information from the core network. Optionally, the service notification information can also indicate the capability information of whether the terminal device supports the wake-up signal. The capability information is reported by the terminal device to the core network in advance, and specifically, the capability information can include whether the terminal device supports the wake-up signal, the time interval between the wake-up signal and the corresponding paging moment, etc. It can be understood that the time interval between the wake-up signal and the corresponding paging moment represents the minimum time interval between the wake-up signal and the PO, and the minimum time interval can be related to the processing capability of the terminal device.

[0133] In another implementation manner, the service type to be notified can be stored locally by the network device, such as one or more of the information related to the multicast service and / or the broadcast service, such as the service identity (Service ID), TMGI, MBS Indicator, service type (such as multicast service, broadcast service), etc. The embodiments of the present application do not limit the manner of obtaining the content of the service notification information.

[0134] The network device determines whether to perform the action performed by the network device in S102 according to the service type to be notified.

[0135] In one implementation, when the service type to be notified includes unicast service, the network device determines to perform the action performed by the network device in S102. For example, the service type to be notified is unicast service, or the service type to be notified includes unicast service and multicast service, or the service type to be notified includes unicast service, multicast service and broadcast service, at this time, the network device determines to perform the action performed by the network device in S102. Further, if the capability information of the terminal device supporting the wake-up signal is indicated in the service notification information from the core network, the network device needs to determine whether the terminal device supports receiving the wake-up signal before determining to perform the action performed by the network device in S102. If it is determined that the terminal device corresponding to the unicast service to be paged does not support receiving the wake-up signal, the network device does not perform S102.

[0136] In another implementation, when the service type to be notified does not include unicast service, the network device determines to perform the action performed by the network device in S103, without performing S102. Alternatively, the network device determines that the terminal device corresponding to the unicast service to be paged does not support receiving the wake-up signal, and also does not perform S102.

[0137] In this step S101a, the action of the network device 110 can be performed by the processing unit 1100, the processor 2100 or the processing circuit 3100 of the aforementioned communication apparatus (as a network device).

[0138] S101b, the terminal device 111 determines the service state.

[0139] Specifically, the service state of the terminal device 111 can be unicast service state, or the service state of the terminal device 111 can include multicast service state, or the service state of the terminal device 111 includes broadcast service state, or the service state of the terminal device 111 can include multicast service state and broadcast service state. The explanation of the service state can be referred to the above, which is not repeated here.

[0140] When the service state of the terminal device 111 is unicast service state, the terminal device performs the action of the terminal device in S102, such as detecting the first wake-up signal from the network device. When the service state of the terminal device 111 includes multicast service state and / or broadcast service state, the terminal device skips S102 and performs the action of the terminal device in S103.

[0141] Generally, the network device pings a group of terminal devices at the same time, which can include one or more terminal devices, such as the group of terminal devices can include the terminal device 111 and the terminal device 112. The network device can divide the terminal devices into different groups according to the identification information of the terminal devices, such as the temporary mobile subscriber identity (TMSI). The terminal devices in the same group wake up at the same paging occasion (PO) to detect or receive the paging message. The application does not describe in detail which terminal devices are divided into a group.

[0142] Among the group of terminal devices, the service states of different terminal devices can be different, such as the service state of the terminal device 111 is a unicast service state, and the service state of the terminal device 112 can include a multicast service state and / or a broadcast service state.

[0143] If the service state of the terminal device 111 includes a multicast service state and / or a broadcast service state, even if the network device 110 sends the first wake-up signal (such as the network device determines that the service notification information for the group of terminal devices includes unicast service), the terminal device 111 does not perform S102, i.e., does not detect the first wake-up signal, or ignores the first wake-up signal.

[0144] If the service state of the terminal device 111 is a unicast service state, the terminal device 111 detects the first wake-up signal, regardless of whether the network device sends the first wake-up signal.

[0145] The action of the terminal device 111 in this step S101b can be performed by the processing unit 1100, the processor 2100 or the processing circuit 3100 of the aforementioned communication apparatus (as a terminal device).

[0146] S102, the network device 110 sends the first wake-up signal to the terminal device 111.

[0147] As described above, when the network device determines that the type of service to be notified includes unicast service, the network device can send the first wake-up signal. This is not described here. Alternatively, the network device sends the first wake-up signal according to the type of service to be notified including unicast service, at this time, step S201a is optional, i.e., the network device can not have the action of explicitly determining the type of service to be notified.

[0148] Correspondingly, when the service state of the terminal device 111 is a unicast service state, it is determined to detect the first wake-up signal. Alternatively, the terminal device determines to detect the first wake-up signal according to the service state being a unicast service state, at this time, step 101b is optional, i.e., the terminal device wants to have the action of not electrically welding the service state to be a unicast service state.

[0149] The first wake-up signal is used to indicate the terminal device to detect the first information. When the terminal device detects the first wake-up signal, it means that the terminal device needs to further receive the first information. When the terminal device attempts to detect the first wake-up signal but does not detect (receive) the first wake-up signal, the terminal device no longer receives the first information, but waits for the paging occasion corresponding to the next paging cycle or the time corresponding to the first wake-up signal, and then detects the first wake-up signal according to the service state.

[0150] Figure 6 An example of the terminal device detecting the first wake-up signal and the service notification information is shown. In Figure 6 (A) takes the service state of the terminal device as the unicast service state, the service notification information as the paging, and the first information as the downlink control information as an example for illustration. As shown in Figure 6 (A), before each paging occasion in a paging cycle, the terminal device first detects the first wake-up signal corresponding to the paging occasion. Specifically, before the paging occasion 1, the terminal device wakes up to attempt to detect the first wake-up signal, but does not detect the first wake-up signal, so the terminal device no longer detects the downlink control information and the paging at the paging occasion 1, but remains in sleep until the next paging cycle (paging occasion 2). Before the paging occasion 2, the terminal device wakes up again to detect the first wake-up signal, and if the first wake-up signal is detected, the terminal device further receives the downlink control information and the paging at the paging occasion 2, and performs subsequent processing according to the content in the paging, such as receiving unicast service, receiving multicast service and / or broadcast service, etc. Before the paging occasion 3, the terminal device attempts to detect the first wake-up signal again, but does not detect the first wake-up signal, so the terminal device no longer detects the downlink control information and the paging at the paging occasion 3, but remains in sleep until the next paging cycle, and the rest is omitted.

[0151] In Figure 6 (B) takes the service state of the terminal device as including the multicast service state and / or the broadcast service state, the service notification information as the paging, and the first information as the downlink control information as an example for illustration. As shown in Figure 7 (B), the terminal device detects or receives the downlink control information and the paging at one paging occasion in each paging cycle. Specifically, at the paging occasion 1, the terminal device does not receive the downlink control information and the paging at the paging occasion 1, and remains in sleep until the next paging cycle (paging occasion 2). Before the paging occasion 2, the terminal device wakes up again to detect or receive the downlink control information and the paging, and if the paging is received, subsequent processing is performed according to the content in the paging, such as receiving unicast service, receiving multicast service and / or broadcast service, etc. Before the paging occasion 3, the terminal device attempts to detect the downlink control information and the paging again, and the rest is omitted.

[0152] In an embodiment, the network device first sends configuration information of the first wake-up signal to the terminal device. The corresponding terminal device receives the configuration information of the first wake-up signal. Specifically, the configuration information of the first wake-up signal can be carried in system information or information sent by other network devices in a broadcast manner, and can also be carried in unicast information, such as a radio resource control release (RRC Release) message or other dedicated messages, and the present application does not limit this. The configuration information of the first wake-up signal can include: frequency domain resource location of the WUS, time domain resource location of the WUS, configured maximum WUS duration, minimum time gap from the end of the configured maximum WUS duration to the first associated PO, and the like. In step S102, the action of the network device 110 can be performed by the transceiver unit 1200, the transceiver 2200 or the interface circuit 3200 of the aforementioned communication apparatus (as a network device), and the action of the terminal device 111 can be performed by the transceiver unit 1200, the transceiver 2200 or the interface circuit 3200 of the aforementioned communication apparatus (as a terminal device).

[0153] S103, the network device 110 sends first information to the terminal device.

[0154] Correspondingly, the terminal device 111 detects or receives the first information.

[0155] The first information can be downlink control information (DCI). When the service notification information is paging, the first information can be scrambled using P-RNTI. When the service notification information is system information, the first information can be scrambled using system information-radio network temporary identity (SI-RNTI) or paging-radio network temporary identity (P-RNTI). When the service notification information is MCCH, the first information can be scrambled using multimedia broadcast multicast service-radio network temporary identity (M-RNTI) or P-RNTI.

[0156] Generally, the first information includes at least one of the following: a radio resource (e.g., a physical resource block) used for transmitting the service notification information, a modulation and coding scheme, and the like.

[0157] When the service state of the terminal device 111 is the unicast service state, the terminal device receives the first information according to the detected first wake-up signal. That is, the terminal device receives the first information in response to the detected first wake-up signal. Further, the terminal device receives the service notification information according to the received first information (the action of the terminal device in S104).

[0158] When the service state of the terminal device 111 includes the multicast service state and / or the broadcast service state, the terminal device detects or receives the first information. That is, the terminal device directly detects whether there is the first information at the paging moment, and if the first information is detected (or received), further receives the service notification information according to the first information (the action of the terminal device in S104).

[0159] The action of the network device 110 in the step S103 can be performed by the transceiver unit 1200, the transceiver 2200, or the interface circuit 3200 of the aforementioned communication apparatus (as a network device), and the action of the terminal device 111 can be performed by the transceiver unit 1200, the transceiver 2200, or the interface circuit 3200 of the aforementioned communication apparatus (as a terminal device).

[0160] S104, the network device 110 sends the service notification information to the terminal device.

[0161] Correspondingly, the terminal device 111 receives the service notification information.

[0162] The service notification information can include at least one of the following: a paging, system information, and information carried in MCCH.

[0163] The content in the service notification information can include at least one of the following: identification information of the terminal device to be notified, and identification information of the service to be notified. When the service notification information is a paging, the identification information of the terminal device can be a TMSI, and the identification information of the service to be notified can be a TMGI. The service notification information can also be system information and / or MCCH, and in this case, the identification information of the service to be notified can be a TMGI.

[0164] The content of the service notification information can include a type of the service to be notified.

[0165] The service notification information can be transmitted in a physical downlink shared channel (PDSCH), for example, when the service notification information is a paging or system information.

[0166] Further, the terminal device performs subsequent operation according to the content in the service notification information. Taking paging as an example, when the content in the paging includes the identification information of the terminal device, it is determined that the paging is related to the terminal device, and then the paging is responded to. If the terminal device is in an idle state or an inactive state, the terminal device initiates an RRC connection request process. Alternatively, when the content in the paging includes the identification information of the to-be-notified service, the terminal device determines that the paging is related to the terminal device according to the identification information of the to-be-notified service, that is, whether the identification information of the to-be-notified service is a service of interest to the terminal device, and then the paging is responded to. For example, if the terminal device is in an idle state or an inactive state, the terminal device initiates an RRC connection request process. The service notification information can also instruct the terminal device to read system information and / or MCCH information, and the system information and / or MCCH information can include the identification information of the to-be-notified service. Similarly to the above scheme, the terminal device determines that the paging is related to the terminal device according to the identification information of the to-be-notified service, and then responds to the notification information. For example, if the terminal device is in an idle state or an inactive state, the terminal device initiates an RRC connection request process, or acquires service configuration through broadcast information, and the like.

[0167] In the step S104, the action of the network device 110 can be performed by the transceiver unit 1200, the transceiver 2200 or the interface circuit 3200 of the aforementioned communication apparatus (as a network device), and the action of the terminal device 111 can be performed by the transceiver unit 1200, the transceiver 2200 or the interface circuit 3200 of the aforementioned communication apparatus (as a terminal device).

[0168] The step is optional.

[0169] In the embodiments of the present application, the wake-up signal is introduced, and the wake-up signal is only related to unicast service, so as to reduce unnecessary power consumption of the terminal device. For example, when the service state of the terminal device is a unicast service state, the first wake-up signal is detected, and when the terminal device includes a multicast service state and / or a broadcast service state, the first wake-up signal is not detected. Therefore, when the to-be-notified service type in the service notification information only includes the multicast service state and / or the broadcast service state, on the one hand, the network device does not need to send the first wake-up signal, and on the other hand, the terminal device in the unicast service state does not need to further receive the first information and the service notification information because the first wake-up signal cannot be detected. Therefore, it is beneficial to power saving of the network device and the terminal device. When the proportion of the terminal device in the unicast service state is larger in the system, or when the frequency of the to-be-notified service type in the service notification information only including the multicast service state and / or the broadcast service state is high, better power saving effect can be achieved.

[0170] In another embodiment of the present application, different wake-up signals are designed for different service states. For example, when the service state of the terminal device is a unicast service state, the first wake-up signal is detected; when the service state of the terminal device includes a multicast service state and / or a broadcast service state, the second wake-up signal is detected; and further, the first wake-up signal can also be detected. In addition to the advantages of the foregoing embodiments, the power consumption of the terminal device in the multicast service state and / or the broadcast service state can be reduced.

[0171] As shown in FIG. 1, Figure 8 The method provided by the embodiment of the present application includes the following steps:

[0172] S201a, the network device 110 determines the service type to be notified. Specifically, this step can refer to S101a.

[0173] In addition, in the step S201a, when the service type to be notified includes a unicast service, the network device determines to perform the action of the network device in S202a. For example, when the service type to be notified includes a unicast service, or when the service type to be notified includes a unicast service and a multicast service, the network device determines to perform the action of the network device in S202a.

[0174] When the service type to be notified includes a multicast service and / or a broadcast service, the network device determines to perform the action of the network device in S202b. For example, when the service type to be notified includes a multicast service and / or a broadcast service, or when the service type to be notified includes a multicast service and / or a broadcast service and a unicast service, the network device determines to perform the action of the network device in S202b.

[0175] It can be understood that when the service type to be notified includes a unicast service, a multicast service and / or a broadcast service, the network device determines to perform the action of the network device in S202a and the action of the network device in S202b.

[0176] S201b, the terminal device 111 determines the service state.

[0177] Specifically, this step can refer to S101b.

[0178] The difference between this step S201b and S101b is that when the service state of the terminal device 111 is a unicast service state, the terminal device performs the action of the terminal device in S202a to detect the first wake-up signal from the network device. When the service state of the terminal device 111 includes a multicast service state and / or a broadcast service state, the terminal device performs the action of the terminal device in S202b. Further, when the service state of the terminal device 111 includes a multicast service state and / or a broadcast service state, the terminal device can also perform the action of the terminal device in S202a.

[0179] S202a, the network device 110 sends the first wake-up signal to the terminal device 111.

[0180] In an implementation, the actions of the network device in S201a and S202a can be replaced by the network device sending the first wake-up signal according to the to-be-notified service type including unicast service, at this time, it can be understood that step S201a is optional, i.e., the network device can not have the action of explicitly determining the to-be-notified service type.

[0181] Correspondingly, when the service state of the terminal device 111 is the unicast service state, it is determined to detect the first wake-up signal.

[0182] In an implementation, the actions of the terminal device in S201b and S202a can be replaced by the terminal device 111 detecting the first wake-up signal according to the service state being the unicast service state. At this time, it can be understood that step S201b is optional.

[0183] Specifically, this step can refer to S102.

[0184] S202b, the network device 110 sends the second wake-up signal to the terminal device 111.

[0185] In an implementation, the actions of the network device in S201a and S202b can be replaced by the network device sending the second wake-up signal according to the to-be-notified service type including multicast service and / or broadcast service, at this time, it can be understood that step S201a is optional, i.e., the network device can not have the action of explicitly determining the to-be-notified service type.

[0186] Correspondingly, when the service state of the terminal device 111 includes the multicast service state and / or the broadcast service state, it is determined to detect the second wake-up signal.

[0187] In an implementation, the actions of the terminal device in S201b and S202b can be replaced by the terminal device 111 detecting the second wake-up signal according to the service state including the multicast service state and / or the broadcast service state. At this time, it can be understood that step S201b is optional.

[0188] Specifically, this step can refer to S102.

[0189] Specifically, this step can refer to S102.

[0190] The second wake-up signal is used to indicate the terminal device to detect the first information. When the terminal device detects the second wake-up signal, it means that the terminal device needs to further receive the first information. When the terminal device attempts to detect the second wake-up signal but does not detect (receive) the second wake-up signal, the terminal device no longer receives the first information, but waits for the paging occasion corresponding to the next paging cycle, and then detects the second wake-up signal according to the service state.

[0191] In the embodiments of the present application, the sequences used by the first wake-up signal and the second wake-up signal can be different, and / or the wireless resources (time domain resources and / or frequency domain resources) used can be different. Further, the periods of the first wake-up signal and the second wake-up signal can also be different, for example, the period of the first wake-up signal is the same as the paging period, the period of the second wake-up signal is N times the paging period, N is greater than 1, etc.

[0192] Figure 8 An example of the terminal device detecting the first wake-up signal, the second wake-up signal and the service notification information is shown. Taking the service notification information as paging and the first information as downlink control information as an example for description.

[0193] In Figure 6 (A), it is assumed that the service state of the terminal device is a unicast service state, which can be referred to Figure 8 (A), which is not described here.

[0194] In an implementation manner, it is assumed that the service state of the terminal device includes a multicast service state and / or a broadcast service state, and the terminal device detects the second wake-up signal. At this time, similar to the process of the terminal device detecting the first wake-up signal, it is not described here.

[0195] In another implementation manner, it is assumed that the service state of the terminal device includes a multicast service state and / or a broadcast service state, and the terminal device detects the first wake-up signal and the second wake-up signal, as shown in Figure 8 (B). At this time, whether the first wake-up signal is detected or the second wake-up signal is detected, the terminal device needs to receive the first information. Further, when the terminal device detects one of the first wake-up signal and the second wake-up signal, it can no longer detect the other wake-up signal, so as to further reduce the power consumption of the terminal. As shown in Figure 7 (B), before the paging occasion 1, the terminal device detects the second wake-up signal, and receives the downlink control information and the paging at the paging occasion 1. Before the paging occasion 2, the terminal device detects the first wake-up signal, and receives the downlink control information and the paging at the paging occasion 2. Before the paging occasion 3, the terminal device does not detect the first wake-up signal and does not detect the second wake-up signal, and does not receive the downlink control information and the paging at the paging occasion 3, and remains in sleep until the next paging cycle (not shown in the figure).

[0196] In an embodiment, the network device sends configuration information of the first wake-up signal and the second wake-up signal to the terminal device. The corresponding terminal device receives the configuration information of the first wake-up signal and the second wake-up signal. Specifically, the configuration information of the first wake-up signal and the second wake-up signal can be carried in system information or information sent by the network device in a broadcast manner, and can also be carried in unicast information, such as a radio resource control release (RRC Release) message or other dedicated messages, and the embodiments of the present application are not limited in this regard. The configuration information of the first wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource, and space domain resource) of the first wake-up signal, and the configuration information can also indicate that the first wake-up signal is associated with a unicast service state. Similarly, the configuration information of the second wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource, and space domain resource) of the second wake-up signal, and the configuration information can also indicate that the second wake-up signal is associated with a broadcast service state and / or a multicast service state. Correspondingly, the terminal device determines the wake-up signal to be detected according to the service state and the configuration information of the first wake-up signal and / or the configuration information of the second wake-up signal.

[0197] S203, the network device 110 sends the first information to the terminal device.

[0198] Correspondingly, the terminal device 111 detects or receives the first information.

[0199] Specifically, this step can refer to S103.

[0200] S204, the network device 110 sends service notification information to the terminal device.

[0201] Correspondingly, the terminal device 111 receives the service notification information.

[0202] Specifically, this step can refer to S104.

[0203] This step is optional.

[0204] In the embodiments of the present application, the first wake-up signal corresponding to the unicast service and the second wake-up signal corresponding to the broadcast service and / or the multicast service are introduced to reduce the power consumption of the terminal device in the unicast service state, and the power consumption of the terminal device in the broadcast service state and / or the multicast service state can also be reduced. For example, when the service state of the terminal device is the unicast service state, the first wake-up signal is detected, and only after the first wake-up signal is detected, the first information and the service notification information are further received. If the first wake-up signal is not detected, the terminal device does not need to receive the corresponding first information and service notification information, thereby achieving the power saving effect. Similarly, when the terminal device includes the multicast service state and / or the broadcast service state, the second wake-up signal (or the first wake-up signal and the second wake-up signal) is detected, and only after the second wake-up signal (or the first wake-up signal and the second wake-up signal) is detected, the first information and the service notification information are further received. If the second wake-up signal is not detected (or neither the first wake-up signal nor the second wake-up signal is detected), the terminal device does not need to receive the corresponding first information and service notification information, thereby achieving the power saving effect.

[0205] In another embodiment of the present application, in Figure 9 The embodiments shown include the first wake-up signal and the second wake-up signal, and further introduce a third wake-up signal, which is respectively for the unicast service, the multicast service and the broadcast service. For example, when the service state of the terminal device is the unicast service state, the first wake-up signal is detected, when the service state of the terminal device includes the multicast service state, the second wake-up signal is detected, and further, the first wake-up signal can also be detected. When the service state of the terminal device includes the broadcast service state, the third wake-up signal is detected, and further, the first wake-up signal and / or the second wake-up signal can also be detected. The embodiments of the present application can reduce the power consumption of the terminal device in different service states.

[0206] As Figure 8 The method provided by the embodiments of the present application includes the following steps:

[0207] S301a, the network device 110 determines the service type to be notified. Specifically, this step can refer to S101a or S201a.

[0208] In addition, in the step S301a, when the service type to be notified includes the unicast service, the network device determines to perform the action of the network device in S302a. For example, when the service type to be notified includes the unicast service, or when the service type to be notified includes the unicast service and the multicast service, the network device determines to perform the action of the network device in S302a.

[0209] When the service type to be notified includes multicast service, the network device determines to perform the action of the network device in S302b, such as when the service type to be notified includes multicast service, or when the service type to be notified includes multicast service and broadcast service, and unicast service, the network device determines to perform the action of the network device in S302b.

[0210] When the service type to be notified includes broadcast service, the network device determines to perform the action of the network device in S302c, such as when the service type to be notified includes broadcast service, or when the service type to be notified includes broadcast service and multicast service, and unicast service, the network device determines to perform the action of the network device in S302c.

[0211] It can be understood that when the service type to be notified includes unicast service, multicast service and broadcast service, the network device determines to perform the action of the network device in S302a, the action of the network device in S302b and the action of the network device in S302c.

[0212] S301b, the terminal device 111 determines the service state.

[0213] Specifically, this step can refer to S101b or S201b.

[0214] The difference between this step S301b and S201b is that when the service state of the terminal device 111 is unicast service state, the terminal device performs the action of the terminal device in S302a to detect the first wake-up signal from the network device. When the service state of the terminal device 111 includes multicast service state, the terminal device performs the action of the terminal device in S302b. Further, when the service state of the terminal device 111 includes multicast service state and / or broadcast service state, the terminal device can also perform the action of the terminal device in S302a. When the service state of the terminal device 111 includes broadcast service state, the terminal device performs the action of the terminal device in S302c. Further, when the service state of the terminal device 111 includes broadcast service state, the terminal device can also perform the action of the terminal device in S302a and / or the action of the terminal device in S302b.

[0215] S302a, the network device 110 sends a first wake-up signal to the terminal device 111.

[0216] Correspondingly, when the service state of the terminal device 111 is unicast service state, it is determined to detect the first wake-up signal.

[0217] Specifically, this step can refer to S102 or S202a.

[0218] S302b, the network device 110 sends a second wake-up signal to the terminal device 111.

[0219] Correspondingly, when the service state of the terminal device 111 comprises the multicast service state, it is determined to detect the second wake-up signal.

[0220] Specifically, the step can refer to S102 or S202b.

[0221] The second wake-up signal is used to instruct the terminal device to detect the first information. When the terminal device detects the second wake-up signal, it means that the terminal device needs to further receive the first information. When the terminal device attempts to detect the second wake-up signal but does not detect (receive) the second wake-up signal, the terminal device no longer receives the first information, but waits for the paging moment corresponding to the next paging cycle, and then detects the second wake-up signal according to the service state.

[0222] S302c, the network device 110 sends a third wake-up signal to the terminal device 111.

[0223] Correspondingly, when the service state of the terminal device 111 comprises the broadcast service state, it is determined to detect the third wake-up signal.

[0224] Specifically, the step can refer to S202b.

[0225] In the embodiments of the present application, the sequences used by the first wake-up signal, the second wake-up signal and the third wake-up signal can be different, and / or the wireless resources (time domain resources and / or frequency domain resources) used can be different. Further, the periods of the first wake-up signal and the second wake-up signal can also be different, for example, the period of the first wake-up signal is the same as the paging period, the period of the second wake-up signal is M times of the paging period, M is greater than 1, etc., the period of the third wake-up signal is N times of the paging period, N is greater than 1, etc.

[0226] In combination with Figure 10 and Figure 8 , the embodiments of the present application provide an example of a terminal device detecting the first wake-up signal, the second wake-up signal, the third wake-up signal and the service notification information. Taking the service notification information as the paging and the first information as the downlink control information as an example for description.

[0227] In an implementation manner, when the service state of the terminal device is the unicast service state, the terminal device detects the first wake-up signal, as shown in Figure 8 (A). Details are not described herein.

[0228] In an implementation manner, when the service state of the terminal device is the multicast service state, the terminal device detects the second wake-up signal, at this time, similar to the process of the terminal device detecting the first wake-up signal, details are not described herein.

[0229] In one implementation, when the service state of the terminal device is the multicast service state, the terminal device detects the first wake-up signal and the second wake-up signal, as shown in Figure 10 (B). Details are not repeated here.

[0230] In one implementation, when the service state of the terminal device is the broadcast service state, the terminal device detects the third wake-up signal. At this time, the process of detecting the first wake-up signal or the second wake-up signal by the terminal device is similar and details are not repeated here.

[0231] In one implementation, when the service state of the terminal device is the broadcast service state, the terminal device detects the first wake-up signal and the third wake-up signal. At this time, the process of detecting the first wake-up signal or the second wake-up signal by the terminal device is similar and details are not repeated here.

[0232] In one implementation, when the service state of the terminal device is the broadcast service state, the terminal device detects the second wake-up signal and the third wake-up signal. At this time, the process of detecting the first wake-up signal or the second wake-up signal by the terminal device is similar and details are not repeated here.

[0233] In one implementation, when the service state of the terminal device is the broadcast service state, the terminal device detects the first wake-up signal, the second wake-up signal, and the third wake-up signal, as shown in Figure 10 At this time, when the terminal device detects any one of the first wake-up signal, the second wake-up signal, and the third wake-up signal, the terminal device needs to receive the first information. Further, when the terminal device detects any one of the first wake-up signal, the second wake-up signal, and the third wake-up signal, it can no longer detect the other two wake-up signals, thereby further reducing the power consumption of the terminal. As shown in Figure 5 Before the paging time 1, the terminal device detects the third wake-up signal, and receives the downlink control information and the paging at the paging time 1. Before the paging time 2, the terminal device detects the first wake-up signal, and receives the downlink control information and the paging at the paging time 2. Before the paging time 3, the terminal device does not detect the first wake-up signal, does not detect the second wake-up signal, and does not detect the third wake-up signal, and therefore does not receive the downlink control information and the paging at the paging time 3, and remains in sleep until the next paging cycle (not shown in the figure).

[0234] In an embodiment, the network device sends configuration information of the first wake-up signal, the second wake-up signal and the third wake-up signal to the terminal device. The corresponding terminal device receives the configuration information of the first wake-up signal, the second wake-up signal and the third wake-up signal. Specifically, the configuration information of the first wake-up signal, the second wake-up signal and the third wake-up signal can be carried in system information or information sent by the network device in a broadcast manner, and can also be carried in unicast information such as a radio resource control release (RRC Release) message or other dedicated messages, and the present application does not limit this. The configuration information of the first wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource and space domain resource) of the first wake-up signal, and can also indicate that the first wake-up signal is associated with unicast service state. Similarly, the configuration information of the second wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource and space domain resource) of the second wake-up signal, and can also indicate that the second wake-up signal is associated with multicast service state. Similarly, the configuration information of the third wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource and space domain resource) of the third wake-up signal, and can also indicate that the third wake-up signal is associated with multicast service state. Correspondingly, the terminal device determines the detected wake-up signal according to the service state and at least one of the configuration information of the first wake-up signal, the configuration information of the second wake-up signal or the configuration information of the third wake-up signal.

[0235] S303, the network device 110 sends the first information to the terminal device.

[0236] Correspondingly, the terminal device 111 detects or receives the first information.

[0237] Specifically, this step can refer to S103 or S203.

[0238] S304, the network device 110 sends service notification information to the terminal device.

[0239] Correspondingly, the terminal device 111 receives the service notification information.

[0240] Specifically, this step can refer to S104 or S204.

[0241] This step is optional.

[0242] In the embodiments of the present application, the first wake-up signal corresponding to the unicast service, the second wake-up signal corresponding to the multicast service, and the third wake-up signal corresponding to the broadcast service are introduced to reduce the power consumption of the terminal device in the unicast service state, and also to reduce the power consumption of the terminal device in the broadcast service state and the multicast service state. For example, when the service state of the terminal device is the unicast service state, the first wake-up signal is detected, and only after the first wake-up signal is detected, the first information and the service notification information are further received. If the first wake-up signal is not detected, the terminal device does not need to receive the corresponding first information and service notification information, thereby achieving the power saving effect. Similarly, when the terminal device includes the multicast service state, the second wake-up signal (or the first wake-up signal and the second wake-up signal) is detected, and only after the second wake-up signal (or the first wake-up signal and the second wake-up signal) is detected, the first information and the service notification information are further received. If the second wake-up signal is not detected (or neither the first wake-up signal nor the second wake-up signal is detected), the terminal device does not need to receive the corresponding first information and service notification information, thereby achieving the power saving effect. Similarly, when the terminal device includes the broadcast service state, the third wake-up signal (or the third wake-up signal, and the first wake-up signal and / or the second wake-up signal) is detected, and only after the third wake-up signal (or the third wake-up signal, and the first wake-up signal and / or the second wake-up signal) is detected, the first information and the service notification information are further received. If the third wake-up signal is not detected (or the first wake-up signal, the second wake-up signal, and the third wake-up signal are not detected), the terminal device does not need to receive the corresponding first information and service notification information, thereby achieving the power saving effect.

[0243] In another embodiment of the present application, the above wake-up signal is further refined. For example, the second wake-up signal in the above embodiment belongs to a second wake-up signal set, the second wake-up signal set includes at least two second wake-up signals, wherein each second wake-up signal in the second wake-up signal set is associated with one service attribute in the service attribute information set, and the second wake-up signal in the second wake-up signal set is used to indicate the first information.

[0244] In one implementation, the network device first sends the configuration information of the second wake-up signal set to the terminal device, the configuration information of the second wake-up signal set includes the configuration information of at least two second wake-up signals, wherein the configuration information of each second wake-up signal can indicate the radio resource (one or more of time domain resource, frequency domain resource, code domain resource, and space domain resource) of the corresponding second wake-up signal, and can also indicate that the service state associated with the second wake-up signal is the service state corresponding to one service attribute information in the service attribute information set. Correspondingly, the terminal device determines the detected second wake-up signal according to the service state and the configuration information of the second wake-up signal set.

[0245] In an embodiment, the network device obtains the set of service attribute information from the core network before sending the configuration information of the second set of wake-up signals to the terminal device.

[0246] The process of the embodiments of the present application is similar to the process of the above-described embodiments, and will not be described here. Only the mentioned content not described in the above-described embodiments will be described below. Figure 7 Figure 9 ​ The process of the embodiments of the present application is similar to the process of the above-described embodiments, and will not be described here. Only the mentioned content not described in the above-described embodiments will be described below.

[0247] In the embodiments of the present application, the set of service attribute information includes at least one of a set of service identification information, a set of service type information, a set of quality of service (QoS) requirement information, or a set of service notification frequency information. The set of service attribute information includes at least two service attribute information. Further, the terminal device determines to detect a second wake-up signal associated with the service attribute information in the second set of wake-up signals according to the service state (or the service attribute information).

[0248] It can be understood that when the service state of the terminal device includes a service state corresponding to one or more service attribute information, the terminal device detects one or more second wake-up signals associated with the one or more service attribute information.

[0249] For example, the set of service identification information can include the identification of at least two multicast services, such as TMGI. Specifically, different TMGIs are divided into groups, and each group of TMGIs represents a service attribute information. Each group of TMGIs includes at least one TMGI. For example, each TMGI can form a group. Alternatively, according to the size of TMGI, a plurality of TMGIs are divided into a group, for example, TMGIs 0-5 form a group, TMGIs 6-10 form a group, and so on. Alternatively, according to the value of TMGI Mod X, different TMGIs are divided into a group, where Mod represents modulo and X is a positive integer. Each group of multicast service identification corresponds to a second wake-up signal. At this time, the service state of the terminal device includes the multicast service state, specifically, the service state of the terminal device includes a service state corresponding to one or more service attribute information, for example, the current service state of the terminal device is a service state corresponding to the service attribute information TMGI 0-5, and the terminal device detects a second wake-up signal associated with the service attribute information TMGI 0-5. Alternatively, the current service state of the terminal device is a service state corresponding to the TMGI with TMGI Mod 10=0, and the terminal device detects a second wake-up signal associated with the TMGI with TMGI Mod 10=0.

[0250] ​​For example, the set of service type information can include at least one of public safety, vehicle-to-everything (V2X), software delivery over wireless, group communications, and Internet of Things (IoT) applications, each of which is associated with a second wake-up signal. The service state of the terminal device includes a multicast service state, which includes a service state corresponding to one or more pieces of service attribute information. For example, the service state of the terminal device is a service state corresponding to a public safety service type, and the terminal device detects a second wake-up signal associated with the public safety service type. Alternatively, the service state of the terminal device is a service state corresponding to V2X, and the terminal device detects a second wake-up signal associated with the V2X service type.

[0251] For example, the set of quality of service (QoS) requirement information can include at least two pieces of multicast service QoS requirement information. In one implementation, the set of multicast service QoS requirement information includes low QoS requirement information and high QoS requirement information, wherein the low QoS requirement information is associated with a second wake-up signal, and the high QoS requirement information is associated with another second wake-up signal. The service state of the terminal device includes a multicast service state, which includes a service state corresponding to one or more pieces of service attribute information. For example, the service state of the terminal device is a service state corresponding to low QoS requirement information, and the terminal device detects a second wake-up signal associated with the low QoS requirement information. Alternatively, the service state of the terminal device is a service state corresponding to high QoS requirement information, and the terminal device detects a second wake-up signal associated with the high QoS requirement information.

[0252] In another implementation, each piece of QoS requirement information in the set of multicast service QoS requirement information includes a different 5QI. The service state of the terminal device includes a multicast service state, which includes a service state corresponding to one or more pieces of service attribute information. For example, the service state of the terminal device is a service state corresponding to 5QI=1, and the terminal device detects a second wake-up signal associated with 5QI=1.

[0253] For example, the information set of the frequency of service notification can include information that the frequency of service notification is equal to or lower than a first domain value, or information that the frequency of service notification is higher than or equal to the first domain value, which is respectively associated with a second wake-up signal. It can be understood that the frequency of service notification can be divided into more detailed groups as needed without limitation. It can be understood that the frequency of service notification of different services can be different. At this time, the service state of the terminal device includes the multicast service state, and specifically, the service state of the terminal device includes the service state corresponding to one or more service attribute information, for example, the service state of the terminal device is the service state corresponding to the information that the frequency of service notification is equal to or lower than the first domain value, and the terminal device detects the second wake-up signal associated with the information that the frequency of service notification is equal to or lower than the first domain value.

[0254] It can be understood that the second wake-up signal mentioned in the embodiments of the present application can be replaced by a third wake-up signal, and the second wake-up signal set can be replaced by a third wake-up signal set. It can also be understood that the second wake-up signal and the third wake-up signal can be further refined in the embodiments of the present application, for example, the second wake-up signal belongs to the second wake-up signal set, each second wake-up signal in the second wake-up signal set is associated with one service attribute in the service attribute information set, the third wake-up signal belongs to the third wake-up signal set, and each third wake-up signal in the third wake-up signal set is associated with one service attribute in the service attribute information set. For specific description, reference can be made to the above description of the embodiments of the present application, which will not be repeated here.

[0255] In the embodiments of the present application, by further refining and grouping the wake-up signal, the power consumption of the terminal device in different service states can be reduced.

[0256] In one implementation scheme, after receiving the first information (such as DCI for scheduling paging) used to indicate service notification information (such as paging), the terminal device will receive the service notification information according to the first information, and then determine whether the service notification information is related to itself according to the content in the service notification information. For example, the terminal device in the unicast service state determines that the service notification information is not related to itself if the content in the service notification information only includes multicast service and / or broadcast service after receiving the service notification information. However, at this time, the terminal device has already received the first information and the service notification information, thereby increasing power consumption. Similarly, the terminal device in the multicast service state determines that the service notification information is not related to itself if the content in the service notification information only includes broadcast service after receiving the service notification information. However, at this time, the terminal device has already received the first information and the service notification information, thereby increasing power consumption.

[0257] In view of this, another embodiment of the present application provides an information sending method and receiving method. In the embodiments of the present application, the first information is used to indicate the service type to be notified, so that the terminal device can quickly determine whether the service notification information is related to itself, thereby reducing the power consumption caused by receiving the service notification information irrelevant to itself.

[0258] Specifically, in the embodiments of the present application, the first information is used to indicate the service type to be notified.

[0259] In an implementation, the service type to be notified can include only broadcast service and / or multicast service, or include broadcast service and / or multicast service and unicast service. For example, 1 bit is used in the first information to indicate that when the 1 bit value is 1, the service notification information is only related to broadcast service and / or multicast service, at this time, the terminal device in unicast service state determines not to receive the service notification information indicated by the first information according to the value of the 1 bit, and when the 1 bit value is 0, the service notification information is not only related to broadcast service and / or multicast service, and the terminal device in any service state receives the service notification information indicated by the first information. It can be understood that the correspondence between the value of the 1 bit and the service type to be notified can be changed, which is not limited in the present application. The same applies below.

[0260] In another implementation, the service type to be notified can include broadcast service and / or multicast service and / or unicast service. For example, 2 bits are used in the first information to indicate that 1 bit value is used to indicate whether to notify broadcast service and / or multicast service, for example, the value "1" indicates to notify broadcast service and / or multicast service, and the value "0" indicates not to notify broadcast service and / or multicast service. Another 1 bit value indicates whether to notify unicast service, for example, the value "1" indicates to notify unicast service, and the value "0" indicates not to notify unicast. Correspondingly, the 2 bit value "01" indicates that the service type to be notified is not to notify broadcast service and / or multicast service, but to notify unicast service. The value "10" indicates that the service type to be notified is to notify broadcast service and / or multicast service, but not to notify unicast service. The value "11" indicates that the service type to be notified is to notify broadcast service and / or multicast service, and also to notify unicast service. Correspondingly, the terminal device determines whether to receive the service notification information according to the service state and the 2 bit value in the first information. For example, when the service state of the terminal device is unicast service state, if the above-mentioned 2 bit value is "10", it is determined not to receive the service notification information indicated by the first information. If the above-mentioned 2 bit value is "01" or "11", it is determined to receive the service notification information indicated by the first information.

[0261] In another implementation, the service type to be notified can include at least one of a broadcast service, a multicast service, and a unicast service. For example, 3 bits are used in the first information to indicate the service type to be notified. One bit is used to indicate whether the broadcast service is notified, such as a value of "1" indicating that the broadcast service is notified, and a value of "0" indicating that the broadcast service is not notified. The second bit is used to indicate whether the multicast service is notified, such as a value of "1" indicating that the multicast service is notified, and a value of "0" indicating that the multicast service is not notified. The third bit is used to indicate whether the unicast service is notified, such as a value of "1" indicating that the unicast service is notified, and a value of "0" indicating that the unicast service is not notified. Correspondingly, the 3-bit value of "001" indicates that the service type to be notified is that the broadcast service and the multicast service are not notified, and the unicast service is notified. The 3-bit value of "110" indicates that the service type to be notified is that the broadcast service and the multicast service are notified, and the unicast service is not notified. The 3-bit value of "111" indicates that the service type to be notified is that the broadcast service, the multicast service, and the unicast service are notified. Correspondingly, the terminal device determines whether to receive the service notification information according to the service state and the 3-bit value in the first information. For example, when the service state of the terminal device is the unicast service state, if the 3-bit value is "110", it is determined that the service notification information indicated by the first information is not received. If the 3-bit value is "001" or "011" or "111", it is determined that the service notification information indicated by the first information is received.

[0262] In another implementation, the service type to be notified includes at least one of a broadcast service, at least one multicast service in a multicast service set, and a unicast service, where each service in the multicast service set is associated with one service attribute in the service attribute information set in the above embodiment. For example, a plurality of bits are used in the first information to indicate the service type to be notified. One bit is used to indicate whether the broadcast service is notified, such as a value of "1" indicating that the broadcast service is notified, and a value of "0" indicating that the broadcast service is not notified. The second bit is used to indicate whether the unicast service is notified, such as a value of "1" indicating that the unicast service is notified, and a value of "0" indicating that the unicast service is not notified. The other bits are used to indicate whether at least one multicast service in the multicast service set is notified. For example, assuming that there are 2 service attributes in the service attribute set, the plurality of bits are 2 bits, where each bit indicates one service in the multicast service set, such as "10" indicating that the first multicast service in the multicast service set is notified, and the second multicast service in the multicast service set is not notified, "11" indicating that the first multicast service and the second multicast service in the multicast service set are notified, and so on. Correspondingly, the terminal device determines whether to receive the service notification information according to the service state and the plurality of bit values in the first information. The implementation method is similar to the above description, and will not be described again.

[0263] In another implementation, the service type to be notified includes at least one of the following: at least one broadcast service in the broadcast service set, at least one multicast service in the multicast service set, and a unicast service. Each service in the broadcast service set is associated with one service attribute in the service attribute information set in the above embodiment, and each service in the multicast service set is associated with one service attribute in the service attribute information set in the above embodiment. Accordingly, the terminal device determines whether to receive the service notification information according to the service state and the values of the multiple bits in the first information. The implementation method is similar to the above description and will not be repeated here.
