Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a wake-up signal transmission method, receiving method and apparatus, and storage medium. Background Technology

[0002] To extend the battery life of terminals, the 3rd Generation Partnership Project (3GPP) considered introducing a low-power wake-up signal (LP-WUS) mechanism in Release 18. This mechanism involves the terminal using a separate receiver to receive or detect a wake-up signal. Upon receiving or detecting the wake-up signal, the terminal wakes up the main receiver, which then receives data. When the terminal does not detect a wake-up signal, the main receiver remains in deep sleep or is turned off. This further reduces the terminal's power consumption. However, the specific structure of the wake-up signal in the LP-WUS mechanism has not yet been determined. Summary of the Invention

[0003] This application provides a wake-up signal sending method, receiving method and apparatus, and storage medium to determine a reasonable wake-up signal structure to meet the low power consumption requirements of the terminal.

[0004] On the one hand, a method for sending a wake-up signal is provided, including:

[0005] Generate a wake-up signal, which includes a wake-up preamble and wake-up data;

[0006] Send a wake-up signal.

[0007] On the other hand, a method for receiving a wake-up signal is provided, including:

[0008] The wake-up signal is received by the first receiver. The wake-up signal includes a wake-up preamble and wake-up data.

[0009] The operating mode of the second receiver is determined based on the wake-up signal.

[0010] On the other hand, a base station is provided, comprising:

[0011] The processing module is used to generate a wake-up signal, which includes a wake-up preamble and wake-up data.

[0012] The communication module is used to send wake-up signals.

[0013] On the other hand, a terminal is provided, including:

[0014] The communication module is used to receive a wake-up signal through the first receiver. The wake-up signal includes a wake-up preamble and wake-up data.

[0015] The processing module is used to determine the operating mode of the second receiver based on the wake-up signal.

[0016] In another aspect, a communication device is provided, including a processor, which, when executing a computer program, implements the method for sending a wake-up signal as described in the first aspect, or the method for receiving a wake-up signal as described in the second aspect.

[0017] In another aspect, a computer-readable storage medium is provided, which includes computer instructions; wherein, when the computer instructions are executed, the method for sending a wake-up signal as described in the first aspect is implemented, or the method for receiving a wake-up signal as described in the second aspect is implemented.

[0018] In this embodiment, the wake-up signal includes not only a wake-up preamble but also wake-up data. Therefore, the terminal can determine whether to turn on the second receiver based on the wake-up data in the wake-up signal, instead of keeping the second receiver constantly on. In this way, the terminal's second receiver remains in a closed state for extended periods, only turning on when needed, thus meeting the terminal's low-power consumption requirements.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0037] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0038] In the embodiments of this application, "instruction" can include direct instruction and indirect instruction. For example, taking the first control information as an example below, the first control information can directly carry information A itself or its index to achieve the purpose of directly instructing information A. Alternatively, the first control information can also carry information B that is related to information A, thereby achieving the purpose of indirectly instructing information A while instructing information B.

[0039] The technical solutions provided in this application can be applied to various communication systems, such as New Radio (NR) communication systems using 5G communication technology, future evolution systems, or multiple communication convergence systems.

[0040] For example, Figure 1 The figure shows a schematic diagram of a communication system provided in an embodiment of this application. The communication system may include a base station and multiple terminals (terminal 1 and terminal 2 in the figure), and the base station may communicate with one or more of the terminals.

[0041] Base stations can be used to implement functions such as terminal resource scheduling, wireless resource management, and wireless access control. Specifically, a base station can be any of the following: a small base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), or some other type of access node.

[0042] A terminal can be a terminal itself, or a device with terminal functionality. A terminal can also be called a user equipment (UE), mobile station, mobile terminal, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality terminal, augmented reality terminal, wireless terminal in industrial control, wireless terminal in autonomous driving, wireless terminal in remote surgery, wireless terminal in transportation safety, wireless terminal in smart cities, wireless terminal in smart homes, and so on. The embodiments of this application do not limit the specific device form used for the terminal.

[0043] In some embodiments, the terminal may be equipped with a first receiver and a second receiver. Optionally, the power consumption of the first receiver in the active state is much lower than that of the second receiver in the active state. The first receiver may have other names, such as wake-up circuit, low-power circuit, wake-up module, etc., and the second receiver may have other names, such as main receiving circuit, main receiving module, main receiving unit, etc., without limitation. In the embodiments of this application, the first receiver is mainly used to support the terminal in receiving signals related to wake-up. The second receiver is used to receive and / or transmit data.

[0044] In some embodiments, the terminal only activates the first receiver. After receiving a wake-up signal from the first receiver, it then activates the second receiver. If the terminal does not receive a wake-up signal, it does not activate the second receiver (at this time, the terminal's state can be called the wake-up state, LP-WUS state, LP-WUS detection state, or other names). This reduces the terminal's power consumption.

[0045] It should be noted that, Figure 1 This is just an example framework diagram. Figure 1 The number of devices included and the names of each device are unlimited, except for... Figure 1 In addition to the devices shown, the communication system may also include other devices, such as core network equipment.

[0046] The application scenarios of the embodiments in this application are not limited. The system architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0047] like Figure 2 As shown in the figure, this application embodiment provides a method for transmitting a wake-up signal, the method including the following steps:

[0048] S101, The base station generates a wake-up signal.

[0049] The wake-up signal is used to wake up terminals in a dormant state. For example, when system messages change, the base station can generate and send a wake-up signal to wake up each terminal to receive the changed system messages. Another example is that after data from a terminal (e.g., terminal A) arrives at the base station, the base station can generate and send a wake-up signal to wake terminal A into a connected state to receive data. Yet another example is that after a terminal finishes sending and receiving data and enters a dormant state, it shuts down its second receiver, leaving only the first receiver in low-power mode, or after a certain period of measurement, if the conditions for shutting down the second receiver are met, it shuts down the second receiver, leaving only the first receiver in low-power mode.

[0050] Optionally, the wake-up signal in the embodiments of this application may have other names, such as wake-up unit, wake-up frame, etc., and there is no limitation on this.

[0051] In some embodiments, the wake-up signal includes a wake-up preamble. The wake-up preamble can be used to assist the terminal's receiver in time and frequency synchronization. Optionally, the bit sequence used in the wake-up preamble can be defined in a standard; alternatively, the bit sequence used in the wake-up preamble can be determined by the base station; or alternatively, the bit sequence used in the wake-up preamble can be negotiated and determined between the base station and the terminal. Besides assisting the terminal in time and frequency synchronization, the wake-up preamble can also carry relevant indication information for wake-up data.

[0052] In some embodiments, the wake-up signal may include wake-up data in addition to a wake-up preamble. For example, such as... Figure 3 As shown, in the wake-up signal, the wake-up preamble is mapped before the wake-up data, so that the terminal can prepare to receive the wake-up data after receiving the wake-up preamble. It should be understood that in... Figure 3 In the structure of the wake-up signal shown, the wake-up preamble can be used to indicate the starting position of the wake-up data.

[0053] In some embodiments, wake-up data includes at least one of the following: SMS message, terminal index, group index, cell index, or data content indication.

[0054] The following describes the information carried by the wake-up data.

[0055] (1) SMS

[0056] The short message includes at least one of the following types: system message change indication, warning message indication, or stop detection indication. The system message change indication indicates a change in the system message. The warning message indication indicates receipt of a warning message. The stop detection indication indicates (on unlicensed spectrum) cessation of detection of wake-up signals.

[0057] For example, the warning information can be warning information about natural disasters or emergencies, such as information from the Earthquake and Tsunami Warning System (ETWS) or the Commercial Mobile Alert System (CMAS).

[0058] As one possible implementation, the wake-up data may include at least one of the following: an indicator bit corresponding to a system message change indicator, an indicator bit corresponding to a warning information indicator, and an indicator bit corresponding to a stop detection indicator.

[0059] The indicator bit corresponding to the system message change indicator can be implemented with one bit. The value of this bit is 0, which indicates that the wake-up data does not carry the system message change indicator; the value of this bit is 1, which indicates that the wake-up data carries the system message change indicator.

[0060] The indicator bit corresponding to the warning information indication can be implemented with a single bit. The value of this bit is 0, indicating that the wake-up data does not carry a warning information indication; the value of this bit is 1, indicating that the wake-up data carries a warning information indication.

[0061] The indicator bit corresponding to the stop detection indication can be implemented with a single bit. A value of 0 indicates that the wake-up data does not carry a stop detection indication; a value of 1 indicates that the wake-up data carries a stop detection indication.

[0062] As another possible implementation, the wake-up data may include an indicator bit corresponding to the SMS message. This indicator bit can be implemented using multiple bits. For example, if the indicator bit is implemented with 2 bits, its value could be 00 (reserved), 01 (indicating the wake-up data carries a system message change indication), 10 (indicating the wake-up data carries a warning information indication), or 11 (indicating the wake-up data carries a stop detection indication).

[0063] (2) Terminal Index

[0064] The terminal index is used to identify the terminal. Optionally, the terminal index may include any of the following: all or part of the bits of the 5G short temporary mobile subscriber identity (5G-S-TMSI), all or part of the bits of the 5G temporary mobile subscriber identity (5G-TMSI), all or part of the bits of the radio network temporary identity (RNTI), or the wake-up identifier.

[0065] The RNTI includes any one of the following: a wake-up-specific RNTI, a UE-specific RNTI, a UE-specific RNTI for wake-up, a UE-specific RNTI for idle state, a UE-specific RNTI for use in the idle state of the most recently connected cell, a UE-specific RNTI for use in the wake-up of the most recently connected cell, or an inactive RNTI.

[0066] Optionally, 5G-S-TMSI and 5G-TMSI can be configured for the terminal by the mobility management network element. RNTI can be configured for the terminal by the base station. The wake-up identifier can be configured for the terminal device by the core network. It should be understood that the configuration methods of the various types of terminal indexes described above are merely exemplary, and the embodiments of this application are not limited thereto.

[0067] In some embodiments, when the wake-up data includes N terminal indices, the N terminal indices can be arranged according to a preset rule, such as arranged in descending order of index values ​​or arranged in ascending order of index values.

[0068] (3) Group Index

[0069] A group index is used to identify a group, which may include one or more terminal devices. In some embodiments, the grouping type may include one or more of the following: a group based on the core network (CN), a group based on a preset terminal index, or a group based on both the CN and the preset terminal index. The preset terminal index may be configured by the base station, negotiated between the base station and the terminal devices, or calculated based on the terminal index.

[0070] (4) Cell Index

[0071] The cell index is used to identify a cell. In this application embodiment, a cell can be a macro cell, micro cell, indoor cell, etc., and is not limited thereto. In some embodiments, the cell index includes all or part of the base station identifier bits, or all or part of the physical layer cell identifier (PCI) bits.

[0072] (5) Data content indication

[0073] In some embodiments, the data content indication includes at least one of the following types: data transmission format indication, data type indication, data length indication, terminal index number indication, group type indication corresponding to group index, data repetition count indication, data bit rate indication, data modulation method indication, or data transmission rate indication.

[0074] The data transmission format indicator is used to indicate the transmission format of the wake-up data.

[0075] The data type indicator is used to indicate the data type in the wake data.

[0076] The data length indicator is used to indicate the length of the wake-up data.

[0077] The Terminal Index Count indicator is used to indicate the number of terminal indexes carried in the wake-up data.

[0078] The grouping type indicator corresponding to the group index is used to indicate the grouping type to which the group index in the wake-up data belongs.

[0079] The data repetition count indicator is used to indicate how many times the information in the wake-up data is repeated.

[0080] The data rate indicator is used to indicate the transmission rate of wake-up data.

[0081] The data modulation mode indicator is used to indicate the modulation mode used for the wake-up data.

[0082] The data transfer rate indicator is used to indicate the rate at which wake-up data is transferred.

[0083] The above is an introduction to the information carried by wake-up data. It should be understood that wake-up data can carry other types of information in addition to SMS messages, terminal indexes, group indexes and cell indexes. This application embodiment does not limit this.

[0084] In some embodiments, the information in the wake-up data can be mapped according to priority.

[0085] For example, the order of priority from highest to lowest can be: SMS, cell index, group index, terminal index.

[0086] For example, the priority order from high to low is: the short message, the group index.

[0087] For example, the priority order from high to low is: the short message, the terminal index.

[0088] For example, the priority order from high to low is: the short message, the group index, and the terminal index.

[0089] For example, the priority order from high to low is: the data content indication, the short message, the group index, and the terminal index.

[0090] For example, the priority order from high to low is: the data content indication, the short message, and the terminal index.

[0091] For example, the priority order from high to low is: the data content indication, the terminal index.

[0092] For example, the priority order from high to low is the data content indication, the SMS message, the cell index, the group index, and the terminal index.

[0093] In some embodiments, the wake-up data further includes at least one of the following: an interval identifier, an end identifier, a sub-preamble, or a checksum. The sub-preamble is used to assist the terminal in synchronizing the wake-up data. The interval identifier is used to separate different parts of the wake-up data. The end identifier is used to indicate the end position of the wake-up data, or the end position of a specific content within the wake-up data. The checksum is used to verify the wake-up data.

[0094] In some embodiments, such as Figure 4 As shown, when the wake-up data includes N terminal indices, at least one of the following is present every K terminal indices: an interval identifier, an end identifier, and a checksum. N is greater than or equal to K, and both N and K are positive integers. The value of K can be predetermined or determined based on the value of N. Optionally, the length of the identifier can be fixed at Y bits. In this way, by segmenting multiple terminal indices using identifiers, even if the K terminal indices before the identifier experience bit shortages due to interference or other factors, it will not affect the terminal device's parsing of the terminal indices after the identifier. Thus, when the wake-up data carries multiple terminal indices, the success rate of the terminal device's parsing of the terminal indices in the wake-up data can be guaranteed, thereby reducing the increased power consumption caused by false wake-ups.

[0095] In some embodiments, where the length of wake-up data is limited, the base station can determine the information carried in the wake-up data based on the priority of various types of information and the length of various types of information.

[0096] For example, if the wake-up data is M bits long and the terminal index is X bits long, then when the wake-up data needs to carry terminal indices, the wake-up data can carry at most floor(M / X) terminal indices. floor() represents rounding down.

[0097] For example, if the wake-up data is M bits long, the terminal index is X bits long, the preset identifier is Y bits long, and the number of preset identifiers is y, then when the wake-up data needs to carry the terminal index and the preset identifier, the wake-up data carries floor(M / (X+Y*y)) terminal indices. The preset identifier is the interval identifier.

[0098] For example, the wake-up data is M bits long, the terminal index is X bits long, the identifier is Y bits long, the number of identifiers is y, and the SMS message is 3 bits long. When both SMS messages and terminal indexes need to be sent, since the SMS message has a higher priority than the terminal index, the wake-up data will carry at most floor((M-3) / (X+Y*y)) terminal indices in addition to the SMS message.

[0099] For example, the wake-up data is M bits long, the terminal index is X bits long, the SMS message is 3 bits long, and the cell index is 6 bits long. Assuming the information to be sent includes an SMS message, a cell index, and K terminal indices, since the priority of the SMS message and cell index is higher than that of the terminal index, the wake-up data can carry at most K1 = floor((M-9) / (X)). Thus, when K1 is greater than or equal to K, the wake-up data includes an SMS message, a cell index, and K terminal indices. Alternatively, when K1 is less than K, the wake-up data includes an SMS message, a cell index, and K1 terminal indices, which are selected from the aforementioned K terminal indices. For example, the K1 terminal indices could be the top K1 terminal indices with the largest index value among the K terminal indices; or, the K1 terminal indices could be the top K1 terminal indices with the smallest index value among the K terminal indices; or, the K1 terminal indices could be randomly selected from the K terminal indices.

[0100] Optionally, the information carried in the wake-up data can be indicated explicitly or implicitly. This allows the terminal device to know the type and quantity of information carried in the wake-up data before receiving it, thus preparing for correct parsing and ensuring a high success rate. Furthermore, the number of bits used to carry information in the wake-up data can be increased or decreased according to actual needs, thereby saving on transmission overhead.

[0101] In some embodiments, the implicit indication can be implemented as follows: the length and / or bit sequence of the wake-up preamble is used to indicate the information carried by the wake-up data. For example, it can be predefined that: corresponding to a first length of the wake-up preamble, the wake-up data carries a short message; corresponding to a second length of the wake-up preamble, the wake-up data carries a terminal index; corresponding to a third length of the wake-up preamble, the wake-up data carries a group index; and corresponding to a fourth length of the wake-up preamble, the wake-up data carries a cell index. As another example, it can be predefined that: corresponding to a first bit sequence of the wake-up preamble, the wake-up data carries a short message; corresponding to a second bit sequence of the wake-up preamble, the wake-up data carries a terminal index; corresponding to a third bit sequence of the wake-up preamble, the wake-up data carries a group index; and corresponding to a fourth bit sequence of the wake-up preamble, the wake-up data carries a cell index. It should be understood that the above examples do not constitute a limitation on the correspondence between the information carried by the wake-up data and the length and / or bit sequence of the wake-up preamble.

[0102] In some embodiments, the explicit indication can be implemented such that the wake-up signal further includes first wake-up indication information, which is used to indicate the information carried by the wake-up data. For example... Figure 5 As shown, in the wake-up signal, the first wake-up indication information can be mapped after the wake-up preamble and before the wake-up data. It should be understood that in... Figure 5 In the structure of the wake-up signal shown, the wake-up preamble can be used to indicate the starting position of the first wake-up indication information. Optionally, the number of bits in the first wake-up indication information is fixed. Thus, after parsing the wake-up preamble from the wake-up signal, the terminal device can naturally determine the starting position of the first wake-up indication information and the wake-up data. It should be understood that the number of bits in the first wake-up indication information can be configured by the base station or specified in the standard.

[0103] As one possible implementation, the first wake-up indication information includes at least one of the following: first indication information, second indication information, third indication information, fourth indication information, fifth indication information, sixth indication information, or seventh indication information.

[0104] The first indication information is used to indicate whether the wake-up data carries a short message. The first indication information can also be called a short message indicator bit. For example, the first indication information can be implemented using a single bit. For instance, a value of 0 indicates that the wake-up data does not carry a short message; a value of 1 indicates that the wake-up data carries a short message.

[0105] The second indication information is used to indicate whether the wake-up data carries a terminal index. The second indication information can also be called a terminal index indication bit. For example, the second indication information can be implemented using a single bit. For instance, a value of 0 indicates that the wake-up data does not carry a terminal index; a value of 1 indicates that the wake-up data carries a terminal index.

[0106] The third indication information is used to indicate whether the wake-up data carries a group index. This third indication information can also be called a group index indicator bit. For example, the third indication information can be implemented using a single bit. For instance, a value of 0 indicates that the wake-up data does not carry a group index; a value of 1 indicates that the wake-up data carries a group index.

[0107] The fourth indication information is used to indicate whether the wake-up data carries the cell index. This fourth indication information can also be called the cell index indication bit. For example, the fourth indication information can be implemented using a single bit. For instance, a value of 0 indicates that the wake-up data does not carry the cell index; a value of 1 indicates that the wake-up data carries the cell index.

[0108] The fifth indication information is used to indicate the type of SMS message carried in the wake-up data. The fifth indication information can also be called the SMS message type indicator bit. The length of the fifth indication information is related to the maximum number of SMS message types.

[0109] The sixth indication information is used to indicate the number of terminal indices carried in the wake-up data. The sixth indication information can also be called the terminal index count indicator bit. The length of the sixth indication information is related to the maximum number of terminal indices carried in the wake-up data. Optionally, the maximum number of terminal indices carried in the wake-up data can be preset. For example, if the maximum number of terminal indices carried in the wake-up data is 7, the length of the sixth indication information is 3 bits.

[0110] The seventh indication information is used to indicate the group type corresponding to the group index carried in the wake-up data. The length of the seventh indication information is related to the number of group types; for example, if the number of group types is 3, the length of the seventh indication information is 2 bits. Table 1, for example, shows the correspondence between the values ​​of the seventh indication information and the group types.

[0113] As another possible implementation, the first wake-up indication information includes an eighth indication information. The value of the eighth indication information corresponds to the information combination of the wake-up data. The information combination includes at least one of SMS, terminal index, group index, or cell index. For example, Table 2 shows possible implementations of the information combination.

[0117] As an example, Table 3 shows an exemplary correspondence between the values ​​of the eighth indication information and the information combination of the wake-up data.

[0120] As another example, Table 4 shows another exemplary correspondence between the values ​​of the eighth indication information and the information combination of the wake-up data.

[0122] The value of the eighth instruction information Information Combination 00 reserve 01 SMS 10 Cell index and terminal index of a terminal 11 Short message, cell index and a terminal index

[0123] In some embodiments, the data content indication and the short message can be jointly indicated in the wake-up data. Based on this, as another example, Table 5 shows another exemplary correspondence between the values ​​of the eighth indication information and the information combination of the wake-up data.

[0124] Table 5

[0125] Information Combination 00 reserve 01 Data content indication 10 SMS 11 Data content instructions and SMS

[0126] As another possible implementation, the first wake-up indication information includes a ninth indication information. The value of the ninth indication information corresponds to the transmission format of the wake-up data, which includes at least one of the following: transmission rate, bit rate, length, repetition count, modulation scheme, or content. For example, Table 6 shows the correspondence between the values ​​of the ninth indication information and the transmission format of the wake-up data. Here, G and H are both positive integers.

[0129] In some embodiments, the wake-up signal may further include second wake-up indication information. This second wake-up indication information indicates the end position of the wake-up data. For example, as shown in FIG6(a) or FIG6(b), the second wake-up indication information is mapped after the wake-up data in the wake-up signal. It should be understood that the second wake-up indication information can be implemented using a preset bit sequence. After the terminal device parses this preset bit sequence from the wake-up signal, it can know that it has received all the wake-up data in the wake-up signal. Thus, based on the start and end positions of the wake-up data in the wake-up signal, the terminal device can determine the length of the wake-up data; based on the length of the wake-up data and the lengths of various types of information within the wake-up data, it can correctly parse the wake-up data.

[0130] In some embodiments, the wake-up signal may further include third wake-up indication information. This third wake-up indication information is used to verify the wake-up data. The third wake-up indication information is generated based on a preset verification algorithm and the wake-up data. For example, as shown in FIG7(a) or FIG7(b), the third wake-up indication information is mapped after the wake-up data in the wake-up signal. It should be understood that if the wake-up data is determined to be incorrect based on the verification using the third wake-up indication information, the terminal device may ignore the wake-up signal; that is, the terminal device will not activate the second receiver based on the relevant information in the wake-up data.

[0131] S102, The base station sends a wake-up signal.

[0132] As one possible implementation, the base station transmits the wake-up signal using binary On-Off Keying (OOK) modulation. It should be understood that using OOK modulation can reduce the implementation complexity of the receiver, thus reducing its cost. Other low-power, low-cost modulation methods are not excluded.

[0133] S103, The terminal device receives the wake-up signal through the first receiver.

[0134] In some embodiments, the terminal device can determine the information on the wake-up data based on the priority of the information. The relevant explanation of priority can be found above and will not be repeated here.

[0135] In some embodiments, when the wake-up signal includes first wake-up indication information, the terminal device can determine the information carried by the wake-up data through the first wake-up indication information.

[0136] Optionally, if the first wake-up indication information includes a first indication information, the terminal device determines whether the wake-up data carries the short message through the first indication information.

[0137] Optionally, if the first wake-up indication information includes the second indication information, the terminal device determines whether the wake-up data carries the terminal index through the second indication information.

[0138] Optionally, if the first wake-up indication information includes the third indication information, the terminal device determines whether the wake-up data carries the group index through the third indication information.

[0139] Optionally, if the first wake-up indication information includes the fourth indication information, the terminal device determines whether the wake-up data carries the cell index through the fourth indication information.

[0140] Optionally, if the first wake-up indication information includes the fifth indication information, the terminal device determines the type of SMS message carried by the wake-up data through the fifth indication information.

[0141] Optionally, if the first wake-up indication information includes the sixth indication information, the terminal device determines the number of terminal indexes carried in the wake-up data through the sixth indication information.

[0142] Optionally, if the first wake-up indication information includes the seventh indication information, the terminal device determines the grouping type corresponding to the group index carried in the wake-up data through the seventh indication information.

[0143] Optionally, if the first wake-up indication information includes the eighth indication information, the terminal device determines the information combination of the wake-up data by the value of the eighth indication information and the correspondence between the eighth indication information and the information combination of the wake-up data.

[0144] Optionally, if the first wake-up indication information includes the ninth indication information, the terminal device determines the transmission format of the wake-up data by the value of the ninth indication information and the correspondence between the ninth indication information and the transmission format of the wake-up data.

[0145] In some embodiments, when the wake-up signal includes second wake-up indication information, the terminal device can determine the end position of the wake-up data through the second wake-up indication information.

[0146] In some embodiments, when the wake-up signal includes third wake-up indication information, the terminal device verifies the wake-up data using the third wake-up indication information.

[0147] In some embodiments, when the wake-up data includes a data content indication, the terminal device can determine information related to the wake-up data through the data content indication.

[0148] S104. The terminal device determines the operating mode of the second receiver based on the wake-up signal.

[0149] As one possible implementation, if the wake-up data carries at least one of the following: the terminal device's own terminal index, the cell index of the cell the terminal device is connected to, the group index of the group to which the terminal device belongs, a system message change indication, or a warning information indication, the terminal device controls the second receiver to start working.

[0150] For example, the terminal device receives Figure 8 The wake-up signal shown, by parsing the first wake-up indication information, reveals that the short message indication bit in the first wake-up indication information is 1, and the other indication bits are 0, thus determining that the wake-up data only carries short messages. When the wake-up data only carries short messages, the terminal device can, based on pre-configuration (e.g., as specified in the standard), determine that the first bit in the wake-up data corresponds to the system message change indication, and the second bit corresponds to the warning information indication. Since the first bit in the wake-up data is 0 and the second bit is 1, the terminal device can determine that the wake-up data carries a warning information indication, and thus the terminal device activates the second receiver to receive the warning information.

[0151] For example, the terminal device receives Figure 9 The wake-up signal shown, by parsing the first wake-up indication information, reveals that the terminal index indicator bit in the first wake-up indication information is 1, while the other indicator bits are 0. This confirms that the wake-up data only carries the terminal index. Furthermore, by parsing the wake-up data, the terminal device can determine that the terminal index carried in the wake-up data is 000000000000001. If the terminal device's own terminal index is 000000000000001, the terminal device will turn on the second receiver to receive the corresponding data. If the terminal device's own index is not 000000000000001, the terminal device will keep the second receiver in the off state.

[0152] For example, the terminal device receives Figure 10 The wake-up signal shown, by parsing the first wake-up indication information, reveals that the terminal index indicator bit is 1 and the terminal index count indicator bit is 011, thus determining that the wake-up data carries three terminal indices. Assuming each terminal index is 4 bits long, the terminal device can determine the three terminal indices as 0111, 0001, and 0101 by parsing the wake-up data. Furthermore, the terminal device can determine whether to activate the second receiver based on whether its own terminal index matches one of these three terminal indices.

[0153] For example, the terminal device receives Figure 11The wake-up signal shown can be analyzed by parsing the first wake-up indication information. This reveals that the group index indicator bit is 1 and the packet type indicator bit is 01, thus determining the group index of the CN-based packet carried in the wake-up data. Assuming the total number of CN-based packets is 4, a corresponding indicator bit can be set for each group index in the wake-up data. Therefore, by parsing the wake-up data, the terminal device can determine that the indicator bit of the 4th group index is 1, confirming that the base station is waking up the terminal device in the 4th group.

[0154] In this embodiment, the wake-up signal includes not only a wake-up preamble but also wake-up data. Therefore, the terminal device can determine whether to turn on the second receiver based on the wake-up data in the wake-up signal, instead of keeping the second receiver constantly on. This way, the second receiver of the terminal device remains in a closed state for extended periods, only turning on when needed, thus meeting the low-power requirements of the terminal device.
