DESCRIPTION OF THE INVENTION

The following clearly describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are only some rather than all of the embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application shall fall within the protection scope of this application.

The following describes terms used in the embodiments of this application.

1. Low-Power Wakeup Signal (LP-WUS)

In a new radio (NR) system, a terminal may include a main communication module and a low-power receiving module, where the main communication module is configured to send and receive mobile communication data, and the low-power receiving module is configured to receive an LP-WUS.

In a case that the terminal is in an energy-saving state, the terminal may control the main communication module to be in a sleep state and control the low-power receiving module to be in a working state. Therefore, in a case that an LP-WUS is received by using the low-power receiving module, the terminal can control the main communication module to be in the working state, and monitor, on a PO in a paging frame (PF) by using the main communication module, whether a physical downlink control channel (PDCCH) carries a paging-radio network temporary identity (P-RNTI), to determine whether a physical downlink shared channel (PDSCH) corresponding to the PDCCH carries a paging message. If the terminal detects that the PDCCH carries the P-RNTI, the terminal may receive the paging message on the corresponding PDSCH based on the P-RNTI, and determine, based on whether a terminal identity of the terminal is included in a terminal identity list in the paging message, whether a network device is paging the terminal.

The LP-WUS may include a preamble and payload data. The preamble may be used for any one of the following: detecting and synchronizing the LP-WUS, determining the payload data, carrying other information, and the like. The payload data is used to carry data.

2. Terminal Group

In the NR system, the network device may classify terminals with a same PO within coverage of the network device into a plurality of terminal groups, so that when the network device pages a terminal, the network device can send a WUS to a terminal group to which the terminal belongs.

However, when the network device pages a target terminal, the network device sends a WUS to a plurality of terminals. Therefore, a case that the network device does not page the target terminal, but the target terminal controls a main communication module to be in a working state to receive a paging message may occur. Consequently, power consumption of the terminal is high.

3. Other Terms

The terms “first”, “second”, and the like in this specification and claims of this application are used to distinguish between similar objects instead of describing a specified order or sequence. It should be understood that the terms used in this way are interchangeable in appropriate circumstances, so that the embodiments of this application can be implemented in other orders than the order illustrated or described herein. In addition, objects distinguished by “first” and “second” usually fall within one class, and a quantity of objects is not limited. For example, there may be one or more first objects. In addition, the term “and/or” in the specification and claims indicates at least one of connected objects, and the character “/” generally represents an “or” relationship between associated objects.

It should be noted that technologies described in the embodiments of this application are not limited to a long term evolution (LTE)/LTE-Advanced (LTE-A) system, and can also be used in other wireless communication systems, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are usually used interchangeably. The described technologies may be used for the foregoing systems and radio technologies, and may also be used for other systems and radio technologies. However, in the following descriptions, the new radio (NR) system is described for an illustrative purpose, and NR terms are used in most of the following descriptions.

The resource location of the first wakeup signal may include at least one of the following: a time domain resource location of the first wakeup signal or a frequency domain resource location of the first wakeup signal.

It may be understood that when the first terminal detects the first wakeup signal, the first terminal may determine that the target wakeup signal is detected.

Therefore, it can be learned that because the first terminal can first determine the first information based on the configuration parameter, and then determine the first wakeup signal whose information matches the first information as the target wakeup signal, accuracy of determining the target wakeup signal can be improved. A case that the network device does not page the first terminal but the first terminal controls the main communication module to be in the working state to receive a paging message is avoided.

Optionally, in another possible implementation of this embodiment of this application, the foregoing step 103 may be implemented by the following step 103c and step 103d.

Step 103c: The first terminal decodes a second wakeup signal based on the configuration parameter to obtain a target identity.

Optionally, in a case that the configuration parameter includes at least one of the configuration parameter of the payload data, the parameter of the terminal information carried by the preamble, or the parameter of the terminal information carried by the payload data, the first terminal decodes the second wakeup signal based on the configuration parameter to obtain the target identity.

In a case that the configuration parameter includes the parameter of the terminal information carried by the preamble, the first terminal may decode a preamble of the second wakeup signal based on the parameter of the terminal information carried by the preamble to obtain the target identity.

In a case that the configuration parameter includes at least one of the configuration parameter of the payload data or the parameter of the terminal information carried by the payload data, the first terminal may decode payload data of the second wakeup signal based on at least one of the configuration parameter of the payload data or the parameter of the terminal information carried by the payload data to obtain the target identity.

In this embodiment of this application, the first terminal determines the second wakeup signal as the target wakeup signal in a case that the target identity matches the terminal identity of the first terminal.

It may be understood that when the first terminal detects the second wakeup signal, the first terminal may determine that the target wakeup signal is detected.

Therefore, it can be learned that because the first terminal can decode the second wakeup signal based on the configuration parameter to obtain the target identity, and determine the second wakeup signal as the target wakeup signal in the case that the target identity matches the terminal identity of the first terminal, accuracy of determining the target wakeup signal can be improved. A case that the network device does not page the first terminal but the first terminal controls the main communication module to be in the working state to receive a paging message is avoided.

The following uses different examples to illustrate how the network device sends the configuration parameter to the first terminal, so that the first terminal can monitor the target wakeup signal.

EXAMPLE 1

In this example, the first message is a system information broadcast message.

The network device may send the system information broadcast message, so that the first terminal can receive the system information broadcast message. The system information broadcast message includes the configuration parameter. The configuration parameter includes at least one of the following: the configuration parameter corresponding to the preamble, the configuration parameter of the payload data, the time domain resource of the wakeup signal, or the frequency domain resource of the wakeup signal. The configuration parameter corresponding to the preamble includes at least one of the following: the quantity of preambles or the quantity of wakeup signals. Therefore, the first terminal can determine the target wakeup signal index (or target preamble index) based on the configuration parameter by using the first algorithm, to monitor the target wakeup signal based on the target wakeup signal index (or target preamble index), where the first algorithm may be:

$\mathrm{LP}-\mathrm{WUS\_index}=\mathrm{UE\_ID}\mathrm{mod}Q,$

• • where Q is an integer greater than 0, Q is the quantity of wakeup signals, UE_ID is at least some bits of the temporary mobile subscriber identity of the first terminal, and LP-WUS_index is the target wakeup signal index (which may also be understood as the target preamble index).

EXAMPLE 2

In this example, the first message includes a system information broadcast message and a NAS message (or RRC message).

The network device may send the system information broadcast message and the NAS message (or RRC message), where the system information broadcast message includes one part of configuration parameters, and the NAS message (or RRC message) includes another part of configuration parameters, so that the first terminal can receive the system information broadcast message and the NAS message (or RRC message) to obtain the configuration parameters. Therefore, the first terminal can determine the target wakeup signal index (or target preamble index) based on the configuration parameters, to monitor the target wakeup signal based on the target wakeup signal index (or target preamble index).

The time of sending the system information broadcast message and the time of sending the NAS message (or RRC message) by the network device are not limited in this example. For example, the network device may send the system information broadcast message before sending the NAS message (or RRC message).

EXAMPLE 3

In this example, the first message includes a system information broadcast message and a NAS message (or RRC message).

The network device may send the system information broadcast message and the NAS message (or RRC message). The system information broadcast message includes one part of configuration parameters. The NAS message (or RRC message) includes another part of configuration parameters. The one part of configuration parameters include at least one of the following: the quantity of terminal groups, the quantity of preambles, the quantity of wakeup signals, time domain resources of the wakeup signals, or frequency domain resources of the wakeup signals. The other part of configuration parameters include: the identity of the target terminal group to which the first terminal belongs. Therefore, the first terminal can receive the system information broadcast message and the NAS message (or RRC message) to obtain the configuration parameters. Therefore, the first terminal can determine the target wakeup signal index (or target preamble index) based on the configuration parameters, to monitor the target wakeup signal based on the target wakeup signal index (or target preamble index).

The first terminal may determine the target wakeup signal index (or target preamble index) based on the configuration parameters by using the second algorithm, where the second algorithm may be:

$\mathrm{LP}-\mathrm{WUS\_index}=\mathrm{index}\mathrm{of}\mathrm{the}\mathrm{target}\mathrm{terminal}\mathrm{group}\mathrm{mod}R,$

• • where R is an integer greater than 0, R is the quantity of wakeup signals, and LP-WUS_index is the target wakeup signal index (which may also be understood as the target preamble index).

It may be understood that each terminal group corresponds to one wakeup signal. Therefore, the identity of the target terminal group may be understood as the target wakeup signal index (or target preamble index). Therefore, the second algorithm can be used to determine the target wakeup signal index (or target preamble index).

The time of sending the system information broadcast message and the time of sending the NAS message (or RRC message) by the network device are not limited in this example.

EXAMPLE 4

In this example, the first message includes a system information broadcast message and a NAS message (or RRC message).

The network device may send the system information broadcast message and the NAS message (or RRC message). The system information broadcast message includes one part of configuration parameters. The NAS message (or RRC message) includes another part of configuration parameters. The one part of configuration parameters include at least one of the following: the quantity of terminal groups, the quantity of preambles, the quantity of wakeup signals, time domain resources of the wakeup signals, or frequency domain resources of the wakeup signals. The other part of configuration parameters include at least one of the following: the identity of the target terminal group to which the first terminal belongs, or indexes of the wakeup signals. Therefore, the first terminal can receive the system information broadcast message and the NAS message (or RRC message) to obtain the configuration parameters. Therefore, the first terminal can determine the target wakeup signal index (or target preamble index) based on the configuration parameters, to monitor the target wakeup signal based on the target wakeup signal index (or target preamble index).

The time of sending the system information broadcast message and the time of sending the NAS message (or RRC message) by the network device are not limited in this example.

EXAMPLE 5

In this example, the first message is a system information broadcast message.

The network device may send the system information broadcast message, so that the first terminal can receive the system information broadcast message. The system information broadcast message includes the configuration parameter. The configuration parameter includes at least one of the following: the configuration parameter corresponding to the preamble, the configuration parameter of the payload data, the time domain resource of the wakeup signal, or the frequency domain resource of the wakeup signal. The configuration parameter corresponding to the preamble includes at least one of the following: the first indication, the second indication, or the N preamble types. The configuration parameter of the payload data includes the third indication, the fourth indication, and the M payload data types. Therefore, the first terminal can monitor the target wakeup signal based on the configuration parameter.

For example, it is assumed that the configuration parameter corresponding to the preamble includes the N preamble types, such as preamble type 1 and preamble type 2. Preamble type 1 includes 2^x preambles, including an x-bit terminal identity, and preamble type 2 includes 2^y preambles, including a y-bit terminal identity. Therefore, the first terminal can determine whether the terminal identity of the first terminal matches the x-bit terminal identity, to determine whether the target wakeup signal is detected, or can determine whether the terminal identity of the first terminal matches the y-bit terminal identity, to determine whether the target wakeup signal is detected.

EXAMPLE 6

In this example, the first message includes a system information broadcast message and a NAS message (or RRC message).

The network device may send the system information broadcast message and the NAS message (or RRC message). The system information broadcast message includes one part of configuration parameters.

The other part of configuration parameters include at least one of the following: the configuration parameter corresponding to the preamble or the configuration parameter of the payload data. The configuration parameter corresponding to the preamble may include at least one of the following: the index of the wakeup signal, the second indication, or the N preamble types. The configuration parameter of the payload data may include at least one of the following: the third indication or the M payload data types. Therefore, the first terminal can receive the system information broadcast message and the NAS messages (or RRC message) to obtain the configuration parameters. Therefore, the first terminal can monitor the target wakeup signal based on the configuration parameters.

The time of sending the system information broadcast message and the time of sending the NAS message (or RRC message) by the network device are not limited in this example.

EXAMPLE 7

In this example, the first message includes a system information broadcast message and a NAS message (or RRC message).

The network device may send the system information broadcast message and the NAS message (or RRC message). The system information broadcast message includes one part of configuration parameters. The NAS message (or RRC message) includes another part of configuration parameters. The one part of configuration parameters include at least one of the following: the quantity of terminal groups, the configuration parameter corresponding to the preamble, the time domain resource of the wakeup signal, or the frequency domain resource of the wakeup signal. The configuration parameter corresponding to the preamble includes at least one of the following: the quantity of preambles or the quantity of wakeup signals. The other part of configuration parameters include at least one of the following: the identity of the target terminal group to which the first terminal belongs, the configuration parameter corresponding to the preamble, or the configuration parameter of the payload data. The configuration parameter corresponding to the preamble includes at least one of the following: the index of the wakeup signal, the second indication, or the N preamble types. The configuration parameter of the payload data includes at least one of the following: the third indication, the fourth indication, or the M payload data types. Therefore, the first terminal can receive the system information broadcast message and the NAS messages (or RRC message) to obtain the configuration parameters. Therefore, the first terminal can monitor the target wakeup signal based on the configuration parameters.

The time of sending the system information broadcast message and the time of sending the NAS message (or RRC message) by the network device are not limited in this example.

In the wakeup signal monitoring method provided in this embodiment of this application, the network device may send the configuration parameter to the first terminal, where the configuration parameter is used to configure the parameter for monitoring the wakeup signal, so that the first terminal can monitor the target wakeup signal based on the configuration parameter, where the target wakeup signal is used to wake up or page the first terminal, where the configuration parameter includes at least one of the following: the configuration parameter corresponding to the preamble; the configuration parameter of the payload data; the time domain resource of the wakeup signal; the frequency domain resource of the wakeup signal; the transmission period parameter of the wakeup signal; the identity of the target terminal group to which the first terminal belongs; the quantity of terminal groups; the parameter of the terminal information carried by the preamble; or the parameter of the terminal information carried by the payload data. Because the network device may send the configuration parameter used to configure the parameter for monitoring the wakeup signal to the first terminal, the first terminal can monitor the target wakeup signal based on the configuration parameter. In other words, the first terminal can accurately monitor the target wakeup signal based on at least one of the following: the configuration parameter corresponding to the preamble, the configuration parameter of the payload data, the time domain resource of the wakeup signal, the frequency domain resource of the wakeup signal, the transmission period parameter of the wakeup signal, the identity of the target terminal group, the quantity of terminal groups, the parameter of the terminal information carried by the preamble, or the parameter of the terminal information carried by the payload data. Therefore, a case that the network device does not page the first terminal but the first terminal controls a main communication module to be in a working state to receive a paging message can be avoided, and power consumption of the first terminal can be reduced.

Certainly, the first terminal may also report preference information to the network device, so that the network device can send the configuration parameter to the first terminal based on the reported preference information, or send an updated configuration parameter to the first terminal again. Assuming that the network device sends the configuration parameter to the first terminal based on the reported preference information, the following uses a example for description.

Optionally, in this embodiment of this application, with reference to FIG. 2, as shown in FIG. 3, before the foregoing step 101, the wakeup signal monitoring method provided in this embodiment of this application may further include the following step 201 to step 203.

For example, the device information of the first terminal may be information about the first terminal being in a stationary state, information about the first terminal moving at a low speed (that is, moving at a speed lower than or equal to a preset speed), information of a high power consumption sensitivity type, information about a battery limitation, and the like.

Optionally, in this embodiment of this application, the preamble preference information includes at least one of the following:

Step 203: The network device determines the configuration parameter based on the configuration preference information.

It may be understood that the network device may provide the configuration parameter for the first terminal based on the configuration preference information reported by the first terminal.

As can be learned, the first terminal may send the configuration preference information used to indicate the preference of the first terminal for the target wakeup signal to the network device, so that the network device can determine the configuration parameter based on the configuration preference information. Therefore, the configuration parameter can properly match the preference of the first terminal for the target wakeup signal, to achieve good communication performance.

Optionally, in this embodiment of this application, with reference to FIG. 3, as shown in FIG. 4, before the foregoing step 201, the wakeup signal monitoring method provided in this embodiment of this application may further include the following step 301 and step 302, and the foregoing step 201 may be implemented by the following step 201b.

Step 301: The network device sends switch configuration information to the first terminal.

In this embodiment of this application, the switch configuration information is used to indicate whether the first terminal is capable of sending the configuration preference information; and the configuration preference information is sent in a case that the switch configuration information indicates that the first terminal is capable of sending the configuration preference information.

The switch configuration information includes a tenth indication, and the tenth indication is used to indicate whether the first terminal is capable of sending the configuration preference information.

For example, the tenth indication may be a configuration of setting up (Setup) the configuration preference information, that is, the tenth indication is used to indicate that the first terminal is capable of sending the configuration preference information, or may be a configuration of releasing (Release) the configuration preference information, that is, the tenth indication is used to indicate that the first terminal is incapable of sending the configuration preference information.

In this embodiment of this application, in the case that the switch configuration information indicates the first terminal to send the configuration preference information, the switch configuration information includes at least one of the following:

• • target indication information;
  • a preferred preamble range; or

  • the target indication information is used to indicate whether the first terminal is capable of sending the device information of the first terminal to the network device.

Optionally, in this embodiment of this application, the preferred preamble range includes at least one of the following:

• • a preferred preamble type;
  • a preferred preamble length; or
  • an eighth indication, where
  • the eighth indication is used to indicate whether the preamble of the target wakeup signal is allowed to be a dynamic preamble; and a preamble type or length of the dynamic preamble is variable.

Optionally, in this embodiment of this application, the preferred payload data range includes at least one of the following:

• • a preferred payload data type;
  • a preferred data length of the payload data; or
  • a ninth indication, where
  • the ninth indication is used to indicate whether the payload data of the target wakeup signal is allowed to be dynamic payload data; and a payload data type, a data length, or a duration of the dynamic payload data is variable.

Optionally, in this embodiment of this application, the foregoing step 301 may be implemented by the following step 301a.

Step 301a: The network device sends a third message to the first terminal.

In this embodiment of this application, the third message includes the switch configuration information, and the third message includes at least one of the following: a NAS message or an RRC message; the NAS message includes any one of the following: a registration accept message, a service accept message, and a tracking area update accept message; and the RRC message includes an RRC reconfiguration message.

Optionally, in this embodiment of this application, the third message may include a plurality of third sub-messages. Each of the plurality of third sub-messages includes a part of switch configuration information.

Step 302: The first terminal receives the switch configuration information from the network device.

Optionally, in this embodiment of this application, the foregoing step 302 may be implemented by the following step 302a.

Step 302a: The first terminal receives the third message from the network device.

In this embodiment of this application, the third message includes the switch configuration information, and the third message includes at least one of the following: a NAS message or an RRC message; the NAS message includes any one of the following: a registration accept message, a service accept message, and a tracking area update accept message; and the RRC message includes an RRC reconfiguration message.

Step 201b: In a case that the switch configuration information indicates the first terminal to send the configuration preference information, the first terminal sends the configuration preference information to the network device based on the switch configuration information.

Therefore, it can be learned that, because the first terminal can send the configuration preference information to the network device only in the case that the switch configuration information indicates the first terminal to send the configuration preference information, instead of directly sending the configuration preference information to the network device, air interface resources can be saved.

Optionally, in this embodiment of this application, before the foregoing step 301, the wakeup signal monitoring method provided in this embodiment of this application may further include the following step 401 to step 403.

Step 401: The first terminal sends second information to the network device.

Step 402: The network device receives the second information from the first terminal.

In this embodiment of this application, the second information is used to indicate the type of wakeup signal supported by the first terminal.

Step 403: The network device determines third information based on the second information.

The third information includes at least one of the following: the configuration parameter or the switch configuration information.

Optionally, in this embodiment of this application, the network device may determine, based on the second information, a parameter that conforms to the type of wakeup signal supported by the first terminal as indicated by the second information, to determine the configuration parameter.

As can be learned, the first terminal may send the second information used to indicate the type of wakeup signal supported by the first terminal to the network device, so that the network device can determine at least one of the configuration parameter or the switch configuration information based on the second information. Therefore, a case that the switch configuration of the configuration preference information does not match due to mismatch of the type of wakeup signal supported by the first terminal can be avoided.
