Background

With the development of indoor positioning, various positioning terminals are widely used in industrial factories, indoor markets, logistics centers and the like. In indoor positioning, the endurance time of the terminal equipment is mostly shorter, so that low-power-consumption positioning becomes a hot topic of current research, the power consumption expense of the terminal equipment is reduced, and the endurance time of the terminal equipment is improved.

In order to achieve low-power-consumption positioning of the terminal equipment and improve the endurance time of a battery of the terminal equipment, an ultra-deep sleep mode scheme is provided. The terminal device may enter an ultra-deep sleep mode to extend the duration of the battery of the terminal device. However, when the terminal device wakes up from the ultra-deep sleep mode, a longer time is required, and the wake-up process consumes more state transition energy, which affects the endurance time of the terminal device. Therefore, how to realize that the terminal device can quickly wake up from the ultra-deep sleep mode to execute the corresponding function is a considerable problem.

The method and the device have the advantages that the terminal device can enter the first sleep mode flexibly in cooperation with the terminal device, the energy consumption of the terminal device is reduced, and the duration of the battery of the terminal device is prolonged.

A first aspect of the present application provides a communication method, including:

The terminal device determines capability information. The terminal device then sends the capability information to the network device. The capability information includes first function information supported by the terminal device after waking up from the first sleep mode. Thereby facilitating the network device to configure the terminal device to perform the corresponding function in combination with the capability information. The terminal equipment can be quickly awakened to execute the function executed by the network equipment configuration terminal equipment after entering the first sleep mode. The method and the device have the advantages that the terminal device can enter the first sleep mode flexibly in cooperation with the terminal device, the energy consumption of the terminal device is reduced, and the duration of the battery of the terminal device is prolonged.

A second aspect of the present application provides a communication method, including:

the network equipment acquires capability information of the terminal equipment, wherein the capability information comprises first function information supported by the terminal equipment after the terminal equipment wakes up from a first sleep mode; the network device determines configuration information for the terminal device according to the capability information, wherein the configuration information comprises second function information configured by the network device for the terminal device. It follows that the network device may configure the terminal device to perform the corresponding function in combination with the capability information. The terminal equipment can be quickly awakened to execute the function executed by the network equipment configuration terminal equipment after entering the first sleep mode. The method and the device have the advantages that the terminal device can enter the first sleep mode flexibly in cooperation with the terminal device, the energy consumption of the terminal device is reduced, and the duration of the battery of the terminal device is prolonged.

Based on the first aspect or the second aspect, in a possible implementation manner, the first function information includes one or more functions of the terminal device; alternatively, the first function information includes one or more function combinations of the terminal device, wherein each function combination includes one or more functions.

In this implementation, two possible implementations of the content comprised by the first functional information are shown. For example, the first function information includes one or more functions of the terminal device. The network equipment is convenient to determine one or more functions supported by the terminal equipment after the terminal equipment wakes up from the first sleep mode based on the first function information, and the network equipment is convenient to configure the terminal equipment to execute corresponding functions. In this way, the terminal device may enter the first sleep mode and may wake up quickly to perform the functions performed by the network device configuration terminal device. For example, the first function information includes one or more function combinations of the terminal device. Thereby facilitating the network device to determine one or more combinations of functions supported by the terminal device after waking from the first sleep mode based on the first function information. The network equipment is convenient to configure the terminal equipment to execute corresponding function combination. In this way the terminal device can enter a first sleep mode and can wake up quickly to perform the combination of functions the network device configures the terminal device to perform.

Based on the first aspect or the second aspect, in one possible implementation manner, when the first function information includes one or more functions of the terminal device, the capability information further includes a wake-up value corresponding to each of the one or more functions; alternatively, when the first function information includes one or more function combinations of the terminal device, the capability information further includes a wake-up value corresponding to each of the one or more function combinations.

In this implementation, some of the content that the capability information also includes is shown. For example, the capability information also includes a wake-up value corresponding to each of the one or more functions. The wake-up value corresponding to each function may reflect, to some extent, information such as time or power required for the terminal device to wake up from the first sleep mode in preparation for executing the function. The network equipment is favorable for combining the wake-up value corresponding to each function to configure the terminal equipment to execute the corresponding function. So that the terminal device can quickly wake up from the first sleep mode to perform the functions of the network device configuration. Alternatively, the capability information may also include, for example, a wake-up value corresponding to each of the one or more combinations of functions. The wake-up value corresponding to each functional combination may reflect to some extent the time or power, etc., required for the terminal device to wake up from the first sleep mode in preparation for executing the functional combination. The network equipment is favorable for combining the wake-up value corresponding to each functional combination to configure the terminal equipment to execute the corresponding functional combination. So that the terminal device can quickly wake up from the first sleep mode to perform the functional combination of the network device configuration. Therefore, the power consumption of the terminal equipment is reduced, and the endurance time of the terminal equipment is prolonged.

Based on the first aspect or the second aspect, in one possible implementation manner, when the first function information includes one or more function combinations of the terminal device, a wake-up value corresponding to each function combination in the one or more function combinations is a sum of wake-up values corresponding to one or more functions included in the function combination, and the wake-up values corresponding to the one or more functions are predefined wake-up values.

In this implementation, another way of determining the corresponding wake-up value for each functional combination is shown. The wake-up value corresponding to each function combination is the sum of the wake-up values corresponding to one or more functions included in the function combination. And the network equipment configures the terminal equipment to execute the corresponding function by combining the wake-up value corresponding to each function. So that the terminal device can quickly wake up from the first sleep mode to perform the functional combination of the network device configuration. Therefore, the power consumption of the terminal equipment is reduced, and the endurance time of the terminal equipment is prolonged.

Based on the first aspect or the second aspect, in one possible implementation manner, an order of a plurality of functions included in each of the one or more function combinations is an order of functions supported to be executed by the terminal device after waking up from the first sleep mode.

In this implementation, the terminal device supports execution of a plurality of functions included in the function combination in order of the plurality of functions after waking up from the first sleep mode. Thus, the wake-up value corresponding to each of the one or more functional combinations refers to: after the terminal equipment wakes up from the first sleep mode, executing wake-up values corresponding to a plurality of functions according to the sequence of the functions included in the function combination. Thereby facilitating the network device to configure the appropriate combination of functions for the terminal device in connection with the order in at least one function included in each of the one or more combinations of functions.

Based on the first aspect or the second aspect, in one possible implementation manner, the capability information further includes one or more correspondence relationships, each of the one or more correspondence relationships includes a correspondence relationship between a wake-up threshold and a wake-up time, and the different correspondence relationships are correspondence relationships between different wake-up thresholds and wake-up times.

In this implementation manner, the capability information further includes one or more corresponding relationships, and when the wake-up value corresponding to the one function or the one function combination is less than or equal to the wake-up threshold in one of the one or more corresponding relationships, the wake-up time required by the terminal device to wake up from the first sleep mode to execute the function or the function combination is indicated as the wake-up time corresponding to the wake-up threshold.

Based on the first aspect or the second aspect, in one possible implementation manner, the one or more functional combinations include at least one of: a functional combination for realizing positioning, a functional combination for realizing downlink positioning, a functional combination for realizing uplink positioning, a functional combination for realizing round trip time positioning, a functional combination for realizing auxiliary positioning of a downlink terminal device, a functional combination for realizing downlink positioning based on the terminal device, or a functional combination for realizing communication and positioning.

In this implementation, some forms of functional combinations are shown, in particular some functional combinations for positioning and functional combinations for enabling communication and positioning. I.e. a full functional combination of terminal devices, i.e. communication and positioning functions possessed by conventional terminal devices. The network device can configure appropriate function combinations for the terminal device in combination with the capability information, so that the terminal device can wake up quickly in the first sleep mode to execute the function combinations configured by the network device.

Based on the first aspect or the second aspect, in one possible implementation manner, the capability information further includes a wake-up time required for the terminal device to wake up from the first sleep mode to implement a function or a combination of functions supported by the terminal device, where the combination of functions includes one or more functions.

In this implementation, the capability information also includes a wake-up time required for the terminal device to wake up from the first sleep mode to achieve the function or combination of functions supported by the terminal device.

Thereby facilitating the network device to configure the terminal device to perform the corresponding function. The terminal device can be quickly awakened in the first sleep mode to execute the function of network device configuration. For example, if the ratio of the energy or power required by the terminal device to prepare to perform a certain function after the terminal device wakes up from the first sleep mode to the energy or power required by the terminal device to perform the function is small, the network device in combination with the service of the terminal device may configure the terminal device to perform the function. If the ratio of the energy or power required by the terminal device to prepare to perform a certain function after waking up from the first sleep mode to the energy or power required by the terminal device to perform the function is large, the network device considers that the energy or power required by the terminal device to prepare to perform a certain function after waking up from the first sleep mode is large. Causing the terminal device to wake up from the first sleep mode requires more energy or power to be consumed. Thus, the network device may not configure the terminal device to perform this function without specific traffic demands.

Thereby facilitating the network device to configure the terminal device to perform the corresponding function combination. The terminal device can be quickly awakened in the first sleep mode to execute the function combination of the network device configuration. For example, if the ratio of the energy or power required by the terminal device to prepare to perform a certain combination of functions after the terminal device wakes up from the first sleep mode to the energy or power required by the terminal device to perform the combination of functions is small, the network device in combination with the service of the terminal device may configure the terminal device to perform the combination of functions. If the ratio of the energy or power required by the terminal device to prepare to perform a certain combination of functions after waking up from the first sleep mode is larger than the energy or power required by the terminal device to perform the certain combination of functions, the network device considers that the energy or power required by the terminal device to prepare to perform the certain combination of functions after waking up from the first sleep mode is larger. Causing the terminal device to wake up from the first sleep mode requires more energy or power to be consumed. Thus, the network device may not configure the terminal device to perform the combination of functions without specific traffic demands.

The access network device is a base station, and the base station is a macro base station, a micro base station (also referred to as a small station), a relay station, an Access Point (AP), a wearable device, an in-vehicle device, or the like in various forms. The base station may also be a transmission receiving node (Transmission and Reception Point, TRP), a transmission measurement function (Transmission measurement function, TMF), etc. Illustratively, the base station to which embodiments of the present application relate may be a base station in a New Radio (NR). Among them, the base station in 5G NR may also be called a transmission reception point (transmission reception point, TRP) or a transmission point (transmission point, TP) or a next generation node B (next generation Node B, ngNB), or an evolved node B (evolutional Node B, eNB or eNodeB) in a long term evolution (long term evolution, LTE) system.

The terminal device may be a wireless terminal device capable of receiving access network device scheduling and indication information. The wireless terminal device may be a device that provides voice and/or data connectivity to a user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

A terminal device, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device including a wireless communication function (providing voice/data connectivity to a user), such as a handheld device having a wireless connection function, an in-vehicle device, etc. Currently, examples of some terminal devices are: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a positioning terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (e.g., an unmanned aerial vehicle, a vehicle), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), or a wireless terminal in smart home (smart home). For example, the positioning terminal device may be a high precision low power consumption positioning (low power high accuracy positioning, LPHAP) terminal device. The LPHAP terminal device has a need for low power location or a need for long endurance.

The communication system applied by the embodiment of the application comprises the terminal equipment and the network equipment, wherein the terminal equipment and the network equipment can execute the communication method provided by the application, and the network equipment can acquire the capability information of the terminal equipment. The capability information includes first function information supported by the terminal device after waking up from the first sleep mode. Thereby facilitating the network device to configure the terminal device to perform the corresponding function in combination with the capability information. The terminal equipment can be quickly awakened to execute the function executed by the network equipment configuration terminal equipment after entering the first sleep mode.

Currently, there is a continued search for ultra-deep sleep modes in the RAN1 conference.

However, when the terminal device wakes up from the ultra-deep sleep mode, a longer time is required, and the wake-up process consumes more state transition energy, which affects the endurance time of the terminal device. Therefore, how to realize that the terminal device can quickly wake up from the ultra-deep sleep mode to execute the corresponding function is a considerable problem. The application provides a corresponding technical scheme, and particularly please refer to the related description of the following embodiments.

Technical terms related to the present application are described below.

Ultra-deep sleep mode): in ultra-deep sleep mode, the terminal device maintains an extremely low current level. For example, the terminal device maintains a current level below a few 10 microamps, with typical values varying between 1 microamps and 10 microamps. In the ultra-deep sleep mode, the terminal device stores only a small amount of codes of functions in the dynamic memory, and the ultra-low power consumption is used for keeping the dynamic memory from power down and maintaining a basic timing clock, and the codes of other functions are stored in the static memory. In this way, the terminal device can keep extremely low current level in the ultra-deep sleep mode, thereby reducing the power consumption of the terminal device. Note that the name of the ultra-deep sleep mode is not limited in this application. For example, the present invention may also be referred to as super deep sleep mode, extreme deep sleep mode, or the like, and is not limited in this application.

Deep sleep mode): in deep sleep mode, the terminal device maintains a low current level. For example, the current level maintained by the terminal device is on the order of milliamps. In the deep sleep mode, the codes of the terminal equipment for realizing most or all functions are stored in the dynamic memory, and the main radio frequency channel and the baseband processing unit of the terminal can be turned off. In this deep sleep mode, the terminal device may maintain a low current level, thereby reducing the power consumption of the terminal device. Note that the name of the deep sleep mode is not limited in this application.

First sleep mode: including ultra-deep sleep mode or deep sleep mode. Of course, the first sleep mode may also be other sleep modes of the terminal device, for example, micro sleep mode (micro sleep mode), which is not limited in the present application.

The monitoring function includes monitoring of a control channel or a shared channel.

One or more functional combinations supported by the terminal device: each functional combination comprises at least one function, and the terminal equipment executes the at least one function, so that execution of a certain service or a plurality of services can be realized. For example, the functional combination includes SSB monitoring and SRS transmission. The functional combination can realize the uplink positioning of the terminal equipment, namely realize the positioning service.

Wake-up load unit (WLU): refers to quantized units of time, energy or power and the like required by hardware and/or loaded software codes to be waken up when the terminal equipment supports a certain function. The name of the wake-up load unit is not limited in this application. For example, the wake-up load unit may also be referred to as a wake-up load unit, a wake-up overhead unit, etc. The specific application is not limited.

Wake-up value: refers to the number of wake-up load units required by the terminal device to perform a certain function or a certain combination of functions after waking up from the first sleep mode. The wake-up value may also be referred to as a wake-up load value, a wake-up overhead value, or a wake-up load unit value, which is not limited by the present application.

Wake-up time: refers to the wake-up time required by the terminal device to perform a certain function or a certain combination of functions after waking up from the first sleep mode. More precisely, it refers to the time required for the terminal device to wake up the hardware and/or load the software code when supporting a certain function or a certain combination of functions.

The following describes the technical scheme of the present application in connection with specific embodiments.

Fig. 4 is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application. Referring to fig. 4, the method includes:

401. the terminal device determines capability information of the terminal device. The capability information of the terminal device includes first function information supported by the terminal device after waking up from the first sleep mode.

For the first sleep mode, please refer to the related description of the foregoing technical terms, and the description thereof will not be repeated here.

Several possible implementations of the first functional information are described below.

The implementation mode is as follows: the first function information includes one or more functions supported by the terminal device after waking up from the first sleep mode.

As described in relation to the preceding technical terms, the one or more functions refer to a communication function, a measurement function, a monitoring function, or the like supported by the terminal device. For example, the one or more functions are shown below in connection with table 1.

TABLE 1

As shown in table 1 above, one or more functions supported by the terminal device after waking from a first sleep mode are shown. For example, the communication functions include PDSCH reception, sounding reference signal transmission, PUSCH transmission, PRACH transmission, and the like. The measurement functions include positioning reference signal reception, etc. The monitoring function includes physical downlink control channel monitoring, synchronization signal/physical layer broadcast channel block synchronization, channel state information reference signal synchronization, tracking reference signal synchronization, etc.

Alternatively, based on implementation one, several possible implementations of the content that the capability information also includes are described below.

Implementation a: the capability information also includes a wake-up value corresponding to each of the one or more functions. For wake-up values, refer to the relevant description of the technical terms mentioned above.

For example, the wake up values for each of the one or more functions are described below in connection with Table 2.

TABLE 2

Function (Activity)	WLU
		PDCCH monitoring	2
PDSCH reception (QPSK modulation only)	3
		PDSCH reception (normal)	5
PRS reception	3
		SRS transmission	1
SSB synchronization	1
		CSI-RS synchronization, or TRS synchronization	1
PUSCH transmission (QPSK modulation only)	3
		PUSCH transmission (normal)	5
PRACH transmission	1
		Radio resource management	3
Signaling resource bearer transport	1
		Data resource bearer transport	1

As can be seen from table 2 above, each function corresponds to a wake-up value, specifically denoted as the number of WLUs. Through the above table 2, the number of WLUs required for the terminal device to support one function after waking up in the first sleep mode can be embodied. The number of WLUs to which the function corresponds may reflect, to some extent, the time required for the terminal device to wake up in the first sleep mode to perform the function. I.e. the time required for the terminal device to accurately perform the function after waking up from the first sleep mode. For the relationship between WLU and wake-up time, refer to the following description of table 8.

It should be noted that, in the foregoing implementation a, the capability information includes a scheme of wake-up values corresponding to each of the one or more functions. In practical applications, the wake-up value corresponding to each of the one or more functions may be predefined or preconfigured by the communication protocol, which is not limited in this application.

Implementation mode B: the capability information also includes a wake-up time corresponding to each of the one or more functions. The wake-up time corresponding to each function refers to a wake-up time required for the terminal device to wake up from the first sleep mode to execute the function. I.e. the wake-up time required for the terminal device to wake-up from the first sleep mode in preparation for performing the function.

For example, the wake-up time for each of the one or more functions is described below in connection with Table 3.

TABLE 3 Table 3

/>

In table 3, each function corresponds to a wake-up time, which is represented by a wake-up time required for the terminal device to prepare to execute the function after the terminal device wakes up in the first sleep mode.

It should be noted that the wake-up time of each function in table 3 is only an example. The wake-up time shown in table 3 is three gears of 2ms, 5ms and 10ms, and in practical application, the wake-up time may be divided into finer gears. For example, four gears of 2ms, 4ms, 6ms, and 10ms, and the present application is not limited thereto. The wake-up time corresponding to each function should be determined in practice in connection with the implementation of the terminal device.

It should be noted that, the foregoing implementation B shows a scheme in which the capability information includes a wake-up time corresponding to each of the one or more functions. In practical applications, the wake-up time corresponding to each of the one or more functions may be predefined or preconfigured by the communication protocol, which is not limited in this application.

Implementation C: the capability information also includes a ratio between an energy or power required by the terminal device to wake up from the first sleep mode to achieve the functionality supported by the terminal device and an energy or power required by the terminal device to perform the functionality supported by the terminal device.

In this implementation, the capability information also includes a ratio between the energy or power required by the terminal device to wake up from the first sleep mode in preparation for performing a function of the terminal device and the energy or power required by the terminal device to perform the function. Thereby facilitating the network device to configure the terminal device to perform the corresponding function based on the capability information.

The implementation mode II is as follows: the first function information includes one or more function combinations supported by the terminal device after waking from the first sleep mode.

As will be appreciated from the relevant description in the foregoing technical terms, each of the one or more combinations of functions includes at least one function. Each functional combination may implement a corresponding service. For example, as shown in table 4 below, the functional combination of PRS reception and PUSCH transmission is applied to downlink terminal equipment assisted positioning services. The functional combination of SSB synchronization and SRS transmission is applied to uplink positioning services. The functional combination of SSB synchronization, PDCCH reception, PDSCH reception (only with QPSK modulation), and SRS transmission is applicable to receiving communication paging and uplink positioning traffic. The full function combination applies to all communication services (e.g., mobility measurements, cell selection, cell reselection, system information reading, paging reception, packet data transmission) and positioning services supported by the terminal in an idle state or an inactive state.

Optionally, the one or more functional combinations include at least one of: the method comprises the steps of a functional combination for realizing positioning, a functional combination for realizing downlink positioning, a functional combination for realizing uplink positioning, a functional combination for realizing round trip time positioning, a functional combination for realizing auxiliary positioning of a downlink terminal device, a functional combination for realizing downlink positioning based on the terminal device, a functional combination for realizing partial communication service (such as paging) and positioning functions, and a functional combination for realizing communication and positioning.

Some of the functional combinations supported by the terminal device are described below in connection with table 4.

TABLE 4 Table 4

Functional combination
	PRS reception+PUSCH transmission
SSB synchronization+SRS transmission
	TRS synchronization+SRS transmission
SSB synchronization+pdcch reception+pdsch reception (only QPSK modulation) +srs transmission
	SSB synchronization+SRS transmission+PDCCH reception+PDSCH reception (normal)
PRS reception+PUSCH transmission+PDCCH reception+PDSCH reception (normal)
	Normal (also known as full function (full functionality))
Downlink positioning
	Uplink positioning
Round trip time positioning
	Auxiliary positioning of downlink terminal equipment
Downlink positioning based on terminal equipment
	Partial communication service (paging) and positioning
Communication and positioning

Table 4 above shows some combinations of functions supported by the terminal device after waking from the first sleep mode. In table 3 above, the normal (normal) functional combination may also be referred to as a full-function combination. The normal function combination refers to a combination having functions of communication, positioning and the like after the conventional terminal equipment wakes up. If the terminal equipment can execute the normal function combination after being awakened from the first sleep mode for a certain time, the terminal equipment is indicated to have communication capability and positioning capability which are possessed by conventional terminal equipment after being awakened from the first sleep mode. For the other functional combinations of table 3 above, the terminal device has limited capabilities after waking up from the first sleep mode, i.e. the terminal device has at least one function of the corresponding functional combination. In this case, the terminal device has the property of being reduced in capability.

Alternatively, based on implementation two, several possible implementations of the content that the capability information also includes are described below.

Implementation 1: the capability information also includes a wake-up value corresponding to each of the one or more combinations of functions. For wake-up values, refer to the relevant description of the technical terms mentioned above.

For example, the corresponding wake-up values for each of the one or more combinations of functions are described below in connection with Table 5.

TABLE 5

/>

As can be seen from table 5 above, each function combination corresponds to a wake-up value, specifically denoted as the number of WLUs.

Optionally, for a combination of functions supported by the terminal device after the terminal device wakes up in the first sleep mode, the order in which the functions in the combination of functions are executed after the terminal device wakes up from the first sleep mode is not limited. For example, for PRS reception+pusch transmission, the terminal device may perform PRS reception first and then PUSCH transmission after waking up from the first sleep mode; or, after the terminal device is updated from the first sleep mode, PUSCH transmission may be performed first, and PRS reception may be performed.

Optionally, the order of the plurality of functions included in each of the one or more combinations of functions is an order of functions that the terminal device supports to execute after waking up from the first sleep mode. In this implementation, for one function combination supported by the terminal device after waking up in the first sleep mode, the terminal device executes a plurality of functions included in the function combination in order of the plurality of functions after waking up from the first sleep mode.

For example, as shown in table 6, the one or more combinations of functions correspond to the number of WLUs.

TABLE 6

In table 6 above, for the functional combinations: SSB synchronization+pdcch reception+pdsch reception (only QPSK modulation) +srs transmission, which corresponds to a number of WLUs of 10. For the functional combination: SSB synchronization+srs transmission+pdcch reception+pdsch reception (normal) its corresponding number of WLUs is 9. The number of WLUs corresponding to each function combination is known to be the number of WLUs required for orderly executing the plurality of functions in the function combination after the terminal device wakes up from the first sleep mode. If the types of functions included in two combinations of functions are the same, but the order of the functions is different, the number of WLUs to which the two combinations of functions correspond may be different. In this implementation, therefore, the number of WLUs corresponding to the functional combinations shown in table 6 above may also be referred to as the number of WLUs corresponding to the ordered functional combinations.

It should be noted that, alternatively, the sequence of the plurality of functions included in the function combination may refer to a reporting sequence in which the terminal device reports the plurality of functions included in the function combination to the network device.

It should be noted that, after the terminal device wakes up from the first sleep mode, the plurality of functions are executed in the order of the plurality of functions included in one function combination. I.e. the terminal device does not perform a function in the combination of functions earlier than the previous one in the combination of functions. If the terminal device executes the function a plurality of times, the execution sequence of the function is determined by the sequence of the first execution of the function by the terminal device. For example, the function combination corresponding to the function a+function b+function c+function B is expressed as the function a+function b+function C.

It should be noted that, the foregoing implementation 1 shows a scheme in which the capability information includes a wake-up value corresponding to each of the one or more function combinations. In practical applications, in one possible implementation, the communication protocol may predefine or pre-configure a wake-up value corresponding to each of the one or more functional combinations. In another possible implementation, the communication protocol may predefine or pre-configure the wake-up value corresponding to the one or more functions. The terminal device sends the capability information to the network device in a later step 402. The network device may determine the wake-up values corresponding to the respective function combinations according to one or more functions supported by the terminal device and the wake-up values corresponding to the one or more functions, which is not limited in this application.

Implementation 2: the capability information also includes a wake-up time corresponding to each of the one or more combinations of functions. The wake-up time corresponding to each function combination refers to a wake-up time required for the terminal device to wake up from the first sleep mode to execute a plurality of functions included in the function combination. I.e. the wake-up time required for the terminal device to prepare to perform the combination of functions after waking up from the first wake-up mode.

For example, the wake-up time for each of the one or more combinations of functions is described below in connection with Table 7.

TABLE 7

It should be noted that, the wake-up time corresponding to each function combination in the above table 7 is only an example. The wake-up time shown in table 7 above is three gears of 25ms, 100ms or 500 ms. In practice, it is possible to divide into finer gears. For example, four gears of 25ms, 50ms, 100ms, and 500ms, the specific application is not limited. The wake-up time corresponding to each functional combination should be determined in practice in connection with the implementation of the terminal device.

It should be noted that, implementation 2 above shows a scheme in which the capability information includes a wake-up time corresponding to each of the one or more function combinations. In practical applications, in one possible implementation, the communication protocol may predefine or pre-configure a wake-up time corresponding to each of the one or more functional combinations. In another possible implementation, the communication protocol may predefine or pre-configure the wake-up time corresponding to the one or more functions. The terminal device sends the capability information to the network device in a later step 402. The network device may determine the wake-up time corresponding to each function combination according to one or more functions supported by the terminal device and the wake-up time corresponding to the one or more functions, which is not limited in this application.

Implementation 3: the capability information further includes a ratio between an energy or power required by the terminal device to wake up from the first sleep mode to achieve a combination of functions supported by the terminal device and an energy or power required by the terminal device to perform the combination of functions supported by the terminal device.

In this implementation, the capability information further includes a ratio between the energy or power required by the terminal device to wake up from the first sleep mode in preparation for performing a combination of functions of the terminal device and the energy or power required by the terminal device to perform the combination of functions. Thereby facilitating the network device to configure the terminal device to perform the corresponding function combination based on the capability information.

Optionally, the capability information further includes one or more correspondence relationships. Each of the one or more correspondences includes a correspondence between a wake-up threshold and a wake-up time, and the different correspondences are correspondences between different wake-up thresholds and wake-up times.

In this implementation, the capability information is shown to further include one or more correspondences. When the wake-up value corresponding to the function is smaller than or equal to the wake-up threshold value in the corresponding relation, the wake-up time required by the terminal equipment to wake up from the first sleep mode to execute the function is the wake-up time corresponding to the wake-up threshold value. Or when the wake-up value corresponding to the function combination is smaller than or equal to the wake-up threshold value in the corresponding relation, the wake-up time required by the terminal equipment to wake up from the first sleep mode to execute the function combination is the wake-up time corresponding to the wake-up threshold value.

For example, one possible example of the one or more correspondences is described below. Please refer to table 8:

TABLE 8

Threshold of WLU (WLU threshold)	Wake-up time (ramp-up time)
		2	20ms
10	100ms
		50	500ms

In table 8 above, the wake-up threshold is represented by the threshold of the WLU. When the number of WLUs corresponding to executing one function or one function combination after the terminal device wakes up from the first sleep mode is less than or equal to 2, it indicates that a wake-up time required for the terminal device to wake up from the first sleep mode to execute one function or one function combination is 20ms. When the number of WLUs corresponding to executing one function or one function combination after the terminal device wakes up from the first sleep mode is greater than 2 and less than or equal to 10, it means that a wake-up time required for the terminal device to wake up from the first sleep mode to execute one function or one function combination is 100ms. When the number of WLUs corresponding to executing one function or one function combination after the terminal device wakes up from the first sleep mode is greater than 10 and less than or equal to 50, it means that a wake-up time required for the terminal device to wake up from the first sleep mode to execute one function or one function combination is 500ms.

For example, as shown in table 6 above, the number of WLUs corresponding to SSB synchronization and SRS transmission performed after the terminal device wakes up from the first sleep mode is 2. Accordingly, the wake-up time required for the terminal device to wake up from the first sleep mode to perform SSB synchronization and SRS transmission is 20ms. For example, as shown in table 6 above, after waking up from the first sleep mode, the terminal device performs PRS reception+pusch transmission+pdcch reception+pdsch reception (normal), and the number of corresponding WLUs is 12. Accordingly, the wake-up time required for the terminal device to wake up from the first sleep mode to perform PRS reception, PUSCH transmission, PDCCH reception, and PDSCH reception (normal) is 500ms.

It should be noted that the one or more corresponding relationships in table 8 are merely an example. The wake-up time shown in table 8 above is three gears of 20ms, 100ms or 500 ms. In practice, it is possible to divide into finer gears. For example, the threshold for WLU is 2 and the corresponding wake-up time is 20ms or 25ms. The threshold for WLU is 5 and the corresponding wake-up time is 50ms. The threshold for WLU is 10 and the corresponding wake-up time is 100ms. The threshold value of WLU is 50, and the corresponding wake-up time is 500ms, which is not limited in this application. The one or more correspondences should be determined in connection with the implementation of the terminal device.

402. The terminal device sends capability information of the terminal device to the network device. Accordingly, the network device receives capability information from the terminal device.

For capability information, refer to the description of the foregoing step 401.

Optionally, the network device is an access network device or a positioning device, which is not limited in this application.

Optionally, the embodiment shown in fig. 4 further includes step 403 and step 404. Steps 403 and 404 may be performed after step 402.

403. And the network equipment determines configuration information for the terminal equipment according to the capability information of the terminal equipment.

The configuration information includes second function information configured by the network device for the terminal device.

Two possible implementations of the second functional information are presented below.

Implementation 1: the second function information includes one or more functions performed by the network device to configure the terminal device.

Specifically, the network device may determine, according to the capability information, a wake-up time required for the terminal device to perform each function supported by the terminal device after the terminal device wakes up from the first sleep mode. The terminal device then determines configuration information for the terminal device based on the wake-up time required for the respective function. The second function information includes one or more functions performed by the network device to configure the terminal device.

Implementation 2: the second function information includes a combination of functions performed by the network device to configure the terminal device.

The network device may determine, based on the capability information, a wake-up time required for the terminal device to wake-up from the first sleep mode to perform the respective combination of functions supported by the terminal device. The terminal device then determines configuration information for the terminal device based on the wake-up time required for the respective functional combination. The second function information includes a combination of functions performed by the network device to configure the terminal device.

For example, the network device is an access network device, the terminal device is a high-precision low-power-consumption positioning (low power high accuracy positioning, LPHAP) terminal device, and the LPHAP terminal device performs uplink positioning in an inactive state. The network equipment combines the capability information of the LPHAP terminal equipment and the service of the LPHAP terminal equipment to determine that the LPHAP terminal equipment needs to perform uplink positioning. And the uplink positioning can be realized by the LPHAP terminal equipment executing SSB synchronization and SRS transmission.

In a possible implementation manner, as can be seen from the foregoing tables 6 and 8, if the network device only configures the lpap terminal device to perform SSB synchronization and SRS transmission, the wake-up time required for the lpap terminal device to wake up from the first sleep mode to perform SSB synchronization and SRS transmission is 20ms. The network device configures the lpap terminal device to perform other functions in addition to SSB synchronization and SRS transmission performed by the lpap terminal device. The wake-up time required for the LPHAP terminal device to wake-up from the first sleep mode to perform the function performed by the network device configuration terminal device is greater than 20ms. For example 100ms, or 500ms. If the LPHAP terminal device has no other service, the network device may configure the terminal device to perform SSB synchronization and SRS transmission, and enable the power saving mode of the LPHAP terminal device, so that the LPHAP terminal device does not receive the paging message. Therefore, the LPHAP terminal equipment can enter a first sleep mode and can be quickly awakened to execute the function executed by the network equipment configuration terminal equipment.

In another possible implementation, the network device configures the LPHAP terminal device to perform SSB synchronization and SRS transmission. The wake-up time required for the LPHAP terminal device to wake-up from the first sleep mode to perform SSB synchronization and SRS transmission is 20ms. The network device also configures the LPHAP terminal device to perform PDCCH monitoring. The wake-up time required for the lpap terminal device to wake up from the first sleep mode to perform the functions the network device configures the lpap terminal device to perform is 25ms. For the network device, the network device considers that the required wake-up time is only 5ms more, and the network device can configure the LPHAP terminal device to monitor the PDCCH, so that the subsequent network device can conveniently page the LPHAP terminal device.

The following describes, in connection with capability information of the terminal device, a wake-up time required by the network device to determine the respective functions supported by the terminal device after the terminal device wakes up from the first sleep mode.

As described above in connection with the implementation of step 401, the capability information of the terminal device includes one or more functions supported by the terminal device after waking up from the first sleep mode.

In one possible implementation, the wake up value for each of the one or more functions is predefined or preconfigured in the communication protocol.

In another possible implementation, the capability information further includes a wake up value corresponding to each of the one or more functions.

Based on the two implementations shown above, the network device may determine a wake-up value for each of the one or more functions. The network device may wake up the terminal device from the first sleep mode to execute the wake-up values corresponding to the functions by taking the sum of the wake-up values corresponding to the functions as the sum of the wake-up values corresponding to the functions.

Optionally, the capability information further includes one or more corresponding relationships, and reference is made to the foregoing related description regarding the one or more corresponding relationships. Alternatively, the one or more correspondence relationships are predefined or preconfigured by the communication protocol, and the application is not limited in this application. And the network equipment determines the wake-up time required by the terminal equipment to wake up from the first sleep mode to execute the functions according to the wake-up quantity corresponding to the functions and the one or more corresponding relations.

For example, the network device determines through table 1 above that the terminal device supports SRS transmission and SSB synchronization after waking up from the first sleep mode. The network device determines by table 2 above: the number of WLUs corresponding to the terminal device waking up from the first sleep mode to perform SSB synchronization is 1, and the number of WLUs corresponding to the terminal device waking up from the first sleep mode to perform SRS transmission is 1. Thus, the network device determines that the number of WLUs corresponding to the terminal device waking up from the first sleep mode to perform SSB synchronization and SRS transmission is summed to 2. The network device can determine that the wake-up time required for the terminal device to wake up from the first sleep mode to perform SSB synchronization and SRS transmission is 20ms, since the sum of the number of WLUs is equal to 2 as shown in table 8.

In yet another possible implementation, the capability information further includes a wake-up time corresponding to each of the one or more functions. In this implementation, the network device may determine a wake time corresponding to each of the one or more functions. The network device wakes up the terminal device from the first sleep mode to execute the wake-up time required by the wake-up time respectively corresponding to the plurality of functions.

The following describes, in connection with capability information of the terminal device, a wake-up time required by the network device to determine the respective function combinations supported by the terminal device after the terminal device wakes up from the first sleep mode.

As in implementation two of step 401 above, the capability information includes one or more combinations of functions supported by the terminal device after waking from the first sleep mode.

In a first possible implementation, the capability information includes a wake-up value corresponding to each of the one or more functional combinations.

In a second possible implementation, the wake-up value corresponding to each of the one or more functional combinations is predefined or preconfigured in the communication protocol.

Based on the two implementations shown above, the network device may determine a corresponding wake-up value for each of the one or more combinations of functions. Optionally, the capability information further includes one or more corresponding relationships, and reference is made to the foregoing related description regarding the one or more corresponding relationships. Alternatively, the one or more correspondence relationships are predefined or preconfigured by the communication protocol, and the application is not limited in this application. And the network equipment determines the wake-up time required by the terminal equipment to wake up from the first sleep mode to execute the function combination according to the wake-up value corresponding to the function combination and the one or more corresponding relations.

In a third possible implementation manner, a wake-up value corresponding to each of one or more functions performed after the terminal device wakes up from the first sleep mode is predefined or preconfigured in the communication protocol.

In a fourth possible implementation manner, the capability information further includes a wake-up value corresponding to each of one or more functions executed by the terminal device after waking up from the first sleep mode.

Based on the third possible implementation manner or the fourth possible implementation manner shown in the foregoing, the network device may determine the wake-up value corresponding to each function combination based on the wake-up value corresponding to each function of the one or more functions. For example, the network device uses the sum of wake values corresponding to each of at least one function included in one function combination as the wake value corresponding to the function combination. Optionally, the capability information further includes one or more corresponding relationships, and reference is made to the foregoing related description regarding the one or more corresponding relationships. Alternatively, the one or more correspondence relationships are predefined or preconfigured by the communication protocol, and the application is not limited in this application. The network device determines a wake-up time required by the terminal device to wake up from the first sleep mode to execute the function combination according to the wake-up value corresponding to each function combination and the one or more corresponding relations.

In a fifth possible implementation, the capability information includes a wake-up time corresponding to each of the one or more functional combinations. In this implementation, the network device may determine a corresponding wake time for each of the one or more combinations of functions.

In a sixth possible implementation manner, the capability information further includes a wake-up time corresponding to each of the one or more functions. In this implementation, the network device may determine a wake time corresponding to each of the one or more functions. The network device wakes up the terminal device from the first sleep mode to execute the wake-up time required by the function combination by taking the sum of the wake-up time respectively corresponding to at least one function included in each function combination as the wake-up time required by the terminal device.

404. The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives configuration information from the network device.

Optionally, the configuration information is carried in an RRC reconfiguration (RRC reconfiguration) message or an RRC release (RRC release) message.

For example, the network device is an access network device, and the terminal device is in a connected state. The access network device may send the configuration information to the terminal device through an RRC reconfiguration message. The configuration information includes that the network device configures the terminal device to perform SSB synchronization and SRS transmission. After the terminal equipment enters the inactive state from the connected state, the terminal equipment can enter a first sleep mode and perform SSB synchronization and SRS transmission after periodically awakening from the first sleep mode.

For example, the network device is an access network device, and the terminal device is in an inactive state or an idle state. The access network device may send the configuration information to the terminal device through an RRC release message. The configuration information includes that the network device configures the terminal device to perform SSB synchronization and SRS transmission. The terminal device may enter a first sleep mode and perform SSB synchronization and SRS transmission after periodically waking up from the first sleep mode.

From this, the network device obtains the capability information of the terminal device. Thereby facilitating the network device to better provide configuration to the terminal device. Therefore, under the condition of ensuring the service requirement of the terminal equipment, the terminal equipment can conveniently enter the first sleep mode, and the energy consumption of the terminal equipment is reduced.

In the embodiment of the application, the terminal equipment determines the capability information. The terminal device then sends the capability information to the network device. The capability information includes first function information supported by the terminal device after waking up from the first sleep mode. Thereby facilitating the network device to acquire the functions or combinations of functions supported by the terminal device after waking from the first sleep mode, and the wake-up time required for the terminal device to perform certain functions or combinations of functions after waking from the first sleep mode.
