By way of example and not limitation, in the present application, the terminal device may be a terminal device in an internet of things (internet of things, ioT) system. The internet of things is an important component of the development of future information technology, and is mainly technically characterized in that objects are connected with a network through a communication technology, so that man-machine interconnection and an intelligent network for the interconnection of the objects are realized. The terminal device in the embodiment of the application may be a wearable device, for example. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. A wearable device is a portable device that may be worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize powerful functions through software support and data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a terminal device in machine type communication (machine type communication, MTC). The terminal device may be a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, a vehicle-mounted unit, or the like, which are built in the vehicle, and the vehicle may implement the method provided in the present application through the built-in vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip, or vehicle-mounted unit, or the like.

The terminal device is provided with a low-power consumption receiver (Low Power Wake Up Receiver, LPWUR) and supports a low-power consumption wake-up signal (Low Power Wake Up Signal, LPWUS) working mode. LPWUR is a special receiver that can operate at very low power consumption to detect and receive specific wake-up signals. Such receivers are commonly used in internet of things (IoT) devices that are in a dormant state most of the time to conserve energy and only wake up when needed. The LPWUS is a specific wake-up signal designed to trigger the wake-up action of the LPWUR. Such a signal typically has a specific frequency, code or format so that the LPWUR can accurately detect it. Once the LPWUR receives the LPWUS, it triggers the wake-up process of the device, causing the device to transition from the sleep state to the active state.

The network device referred to in the present application may be a device that communicates with a terminal device, which may also be referred to as an access network device or a radio access network device, and may be a transmission receiving point (transmission reception point, TRP), an evolved NodeB (eNB or eNodeB) in an LTE system, a home base station (e.g. home evolved NodeB, or home Node B, HNB), a Base Band Unit (BBU), or a radio controller in a cloud radio access network (cloud radio access network, CRAN) scenario, or may be a relay station, an access point, a vehicle device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, or the like, or may be an Access Point (AP) in a WLAN, or may be a gNB in an NR system, or may be a city base station, a micro base station, a pico base station, a femto base station, or the like.

In one network architecture, the network devices may include Centralized Unit (CU) nodes, or Distributed Unit (DU) nodes, or RAN devices including CU nodes and DU nodes, or RAN devices including control plane CU nodes (CU-CP nodes) and user plane CU nodes (CU-UP nodes) and DU nodes.

The network device provides services for the cell, and the terminal device communicates with the cell through transmission resources (e.g., frequency domain resources, or spectrum resources) allocated by the network device, where the cell may belong to a macro base station (e.g., macro eNB or macro gNB, etc.), or may belong to a base station corresponding to a small cell (small cell), where the small cell may include: urban cells (metro cells), micro cells (micro cells), pico cells (pico cells), femto cells (femto cells) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission services.

Currently, the excessive power consumption of the terminal device under 5G is mainly caused by the following aspects:

higher data throughput: the 5G network has an extremely high data transmission speed, which means that the terminal device needs to process more data. To cope with such increased data volume, processors, memories and other components of the terminal device must continue to operate at high speeds, resulting in increased power consumption.

More complex signal processing: the 5G network employs millimeter wave frequency bands and high order modulation techniques that, while improving network performance, increase the complexity of signal processing. The terminal device requires more energy to perform these complex signal processing tasks.

Multiple antennas and multiple connections: terminal devices under 5G are typically equipped with Multiple antennas to support Multiple-Input Multiple-Output (MIMO) technology. Furthermore, in order to maintain a stable network connection, a device may need to establish connections with multiple base stations simultaneously. These additional antennas and connections increase the power consumption of the device.

Sustained energy consumption: the 5G terminal device needs to maintain a continuous connection with the network in order to receive and transmit data in time. This continuous active state can lead to a constant consumption of energy by the device, especially in battery powered devices, where power consumption problems are particularly acute.

In summary, the technical background that the power consumption of the terminal device under 5G is excessive is various. The current method for controlling the power consumption of the terminal equipment by aiming at 5G mainly adopts a low-power-consumption processor, a memory and other hardware components to reduce the basic power consumption of the terminal equipment, or can automatically reduce the working frequency of the hardware of the terminal equipment or enter a sleep mode when the terminal equipment is in an idle or low-load state, thereby reducing the power consumption.

However, the current effect of controlling the power consumption of the terminal device under 5G is not good, and there is still a problem that the power consumption of the terminal device under 5G is higher and the endurance is poor.

In view of this, the present application provides a data transmission method, in which a terminal device sends a target operation mode switching request to a network device to switch between at least two operation modes including an LPWUS mode, and controls network behaviors of the network device and the terminal device according to the operation mode to which the terminal device requests to switch, so as to further control power consumption of the terminal device under 5G, and improve cruising ability of the terminal device.

The data transmission method of the present application will be described in detail with reference to the accompanying drawings. The implementation body of the embodiment shown in the present application is a terminal device or a network device, where the specific form and number of each device shown are only examples, and should not constitute any limitation on the implementation of the method provided in the present application.

The terminal device in the embodiment of the present application may be the terminal device itself, or a chip, a chip system or a processor that supports the terminal device to implement a data transmission method, or may be a logic module or software that can implement all or part of the functions of the terminal device. The network device in the embodiment of the present application may be the network device itself, or a chip, a chip system or a processor that supports the network device to implement a data transmission method, or may be a logic module or software that can implement all or part of the functions of the network device, which is not specifically limited in this application.

Fig. 2 is a flow chart of a data transmission method according to an embodiment of the present application. As shown in fig. 2, the method may include:

s201, the terminal equipment sends first indication information to the network equipment.

Correspondingly, the network equipment receives the first indication information sent by the terminal equipment.

The first indication information is used for indicating the terminal equipment to request to switch to the target working mode. The terminal device supports at least two working modes, wherein the at least two working modes comprise an LPWUS mode, and the power consumption of the terminal device is different in different working modes.

For example, the at least two operation modes supported by the terminal device may include at least two of an LPWUS mode, a first mode, and a second mode, or may further include other operation modes, which are not limited in this application. Taking the example that the two operation modes supported by the terminal device include an LPWUS mode, a first mode, which may be referred to as a low power consumption mode, and a second mode, which may be referred to as a normal mode or a high power consumption mode, the power consumption of the second mode is higher than that of the first mode, and the power consumption of the first mode is higher than that of the LPWUS mode.

The LPWUS mode, the first mode, and the second mode may implement functions of different power consumption in different working modes by changing network behaviors (e.g., information interaction mode, measurement behavior) between the terminal device and the network device, and the like. Therefore, after receiving the first indication information sent by the terminal device, the network device also needs to adjust the network behavior of the terminal device so as to realize the function of switching the terminal device to the target working mode.

In one possible implementation, the first indication information may be sent by the terminal device through a dedicated message or signaling requesting to switch the operation mode. For example, the terminal device may send a switch operation mode message to the network device to transmit the first indication information to the network device.

In another possible implementation, the first indication information may be sent to the network device by the terminal device by adding the content requesting to switch the operation mode in an existing message or signaling. For example, the first indication information may be included in a user equipment assistance information (User Equipment Assistance Information, UAI) message that the terminal device reports to the network device. For example, a Mode Change (UAI) cell may be added to the UAI message, and information of the target working Mode or an identifier of the target working Mode may be stored in the Mode Change cell, so that the network device may obtain, according to the UAI message reported by the terminal device, the target working Mode to which the terminal device requests to switch.

In the foregoing two implementation manners, optionally, the first indication information may be actively reported by the terminal device, for example, after the terminal device triggers a certain condition, the terminal device triggers reporting of the first indication information to the network device. For example, when the terminal device detects that the power consumption reaches a preset threshold value or the electric quantity reaches the preset threshold value, the terminal device triggers the reporting of the first indication information for requesting to switch to the corresponding target working mode. Or the first indication information can be periodically reported by the terminal equipment, and the terminal equipment periodically reports the first indication information according to a preset period, so that the terminal equipment can be periodically switched to a target working mode with lower power consumption, the comprehensive power consumption of the terminal equipment is reduced, and the endurance of the terminal equipment is prolonged.

S202, the network equipment sends second indication information to the terminal equipment.

Correspondingly, the terminal equipment receives the second indication information sent by the network equipment.

Wherein the second indication information is used for indicating the terminal equipment to switch to the target working mode

After the network device receives the first indication information sent by the terminal device, the network behavior between the network device and the terminal device needs to be adjusted according to the target working mode to which the terminal device needs to be switched, so as to change the power consumption of the terminal device. Therefore, the network device also needs to send the second indication information to the terminal device in response to the first indication information, so as to inform the terminal device that the terminal device itself has received the first indication information and knows the target operation mode, and inform the terminal device that the terminal device itself has completed corresponding network behavior adjustment according to the target operation mode.

After receiving the second indication information, the terminal equipment switches the working mode to the target working mode so as to realize the function of changing the power consumption of the terminal equipment.

According to the method provided by the embodiment of the application, the terminal equipment sends the target working mode switching request to the network equipment so as to switch in at least two working modes including the LPWUS mode, and controls the network behavior of the network equipment and the terminal equipment according to the working modes to which the terminal equipment is requested to switch, so that the power consumption of the terminal equipment under 5G is further controlled, and the cruising ability of the terminal equipment is improved.

In the following, the at least two operation modes provided in the embodiments of the present application will be described in detail by taking an example in which the operation modes include an LPWUS mode, a first mode, and a second mode.

Case 1: in different working modes, the information interaction modes of the network equipment and the terminal equipment are different.

LPWUS mode: the network device interacts with the terminal device by just through LPWUS messages.

If the target operation mode is the LPWUS mode, the network device and the terminal device communicate only through the LPWUS message. In this mode, the terminal device may be in a low power consumption state or a sleep state. In this state, the power consumption of the terminal device is extremely low, and almost no electric power is consumed, so that the battery life is prolonged.

At the same time, the LPWUR on the terminal device will continually monitor for the presence of a particular LPWUS message in the environment. If the LPWUR detects a valid LPWUS message (e.g., an LPWUS message sent by the network device to the terminal device), a wake-up mechanism of the terminal device is triggered. After the terminal equipment is awakened, the terminal equipment enters a short active state and performs necessary data receiving, processing or transmitting operation. At this stage, the device will perform the communication tasks associated with the LPWUS message.

After the communication task is completed, the terminal device can return to the low power consumption state or the dormant state as soon as possible, and wait for the arrival of the next LPWUS message.

First mode: the network device interacts with the terminal device through a limited communication mode.

If the target working mode is the first mode, the network equipment and the terminal equipment communicate through a limited communication mode, and the limited communication mode does not comprise the communication by using the LPWUS message. For example, the limited communication mode is to interact only through paging messages.

Taking paging messages as an example, paging messages are messages sent by a network device to inform a terminal device that there is data or instructions to be received. In this communication mode, the terminal device does not need to monitor the channel continuously to receive data, but responds after receiving the paging message. Paging messages typically contain detailed information about the next communication, such as time, frequency, data size, etc. After receiving the paging message, the terminal device performs corresponding operations, such as switching to a specific communication frequency band, preparing to receive data, and the like, according to the indication therein.

Communication using paging messages may effectively reduce power consumption of the terminal device. The terminal device does not need to keep the wake-up state continuously, but responds only when receiving the paging message, thereby reducing the consumption thereof significantly.

Second mode: the network and the terminal device interact through an unlimited communication means.

If the target working mode is the second mode, the network equipment and the terminal equipment communicate through an unlimited communication mode. The unrestricted communication means characterizes the communication between the terminal device and the network device without being limited by a specific time, frequency or signal type. The terminal device may communicate with the network device continuously or on demand without waiting for a specific wake-up signal or paging message.

For example, the terminal device may continuously maintain a connection with the network device so that data may be transmitted in real-time and quickly. This continuous connection ensures low latency and high reliability. Alternatively, the terminal device may interact with the network device through a higher data transmission rate to enhance user experience, etc.

Case 2: in different working modes, the cell measurement behaviors of the control terminal equipment are different.

LPWUS mode and first mode: and controlling the terminal equipment not to conduct cell measurement.

If the target working mode is the LPWUS mode or the first mode, the second indication information is used for indicating the terminal equipment to stop cell measurement.

In a wireless communication system, cell measurement is a critical procedure for a terminal device to evaluate the signal quality and other relevant parameters of the wireless cell in which it is currently located. These measurements help the terminal device decide whether a handover to another cell is required to ensure a continuous, stable communication connection.

Since the LPWUS mode and the first mode need to achieve lower power consumption of the terminal device, performing cell measurement may consume unnecessary energy, and thus the terminal device may stop performing cell measurement after receiving the second indication information indicating that the terminal device may switch to the LPWUS mode and the first mode, so as to reduce power consumption of the terminal device.

Second mode: and controlling the terminal equipment to conduct cell measurement.

And if the target working mode is the second mode, the second indication information is used for indicating the terminal equipment to carry out cell measurement. In the second mode, the terminal device may not control power consumption, so that cell measurement may be started to help the terminal device determine whether to switch to another cell, so as to ensure continuous and stable communication connection, improve mobility of the terminal device, and improve user experience.

Case 3: in different working modes, the information interaction modes of the network equipment and the terminal equipment are different, and the measurement behaviors of the terminal equipment are different.

LPWUS mode: the network device interacts with the terminal device by just LPWUS messages and the terminal device does not make cell measurements.

First mode: the network device interacts with the terminal device in a limited communication manner, and the terminal device does not perform cell measurement.

Second mode: the network and the terminal device interact in an unlimited manner, and the terminal device performs cell measurements.

In the above three cases, optionally, the method further includes the network device adjusting the communication parameter of the network device to the communication parameter corresponding to the target working mode according to the first indication information. Specifically, the network device may determine, according to the target working mode to which the terminal device indicated by the first indication information wishes to switch, an interaction mode between the terminal device and the network device, and/or whether the terminal device needs to start or stop cell measurement behaviors. And if the interaction mode of the terminal equipment and the network equipment needs to be changed, adjusting the communication parameters of the network equipment to the communication parameters corresponding to the target working mode. For example, the communication parameters of the network device are adjusted such that the network device interacts with the terminal device only through LPWUS messages, or the network device interacts with the terminal device through limited communication means (e.g. only through paging messages), or the network device interacts with the terminal device through unlimited means (e.g. the network device and the terminal device remain connected for a long time), etc.

Next, taking the example of determining the target operation mode of the terminal device according to the power information of the terminal device, how to send the first indication information to the network device in the foregoing step S201 will be described in detail. Fig. 3 is a flowchart of another data transmission method according to an embodiment of the present application. As shown in fig. 3, the foregoing step S201 may include:

s301, the terminal equipment determines a target working mode of the terminal equipment according to the electric quantity information of the terminal equipment.

The terminal equipment can acquire the electric quantity information of the terminal equipment according to the attribute parameters of the terminal equipment. For example, the terminal device may monitor its own power status to obtain power information of the terminal device. The power information may be, for example, a remaining power of the terminal device (e.g., state of Charge (SOC)) or a used power of the terminal device. The following description will take the power information as an example of the remaining power of the terminal device.

The electric quantity information and at least two working modes supported by the terminal equipment can have a corresponding relation. For example, when the electric quantity information indicates that the electric quantity of the terminal equipment is smaller than or equal to a first electric quantity threshold value, determining that the target working mode is an LPWUS mode; when the electric quantity information indicates that the electric quantity of the terminal equipment is smaller than or equal to the second electric quantity threshold value and larger than the first electric quantity threshold value, determining that the target working mode is a first mode; and when the electric quantity information indicates that the electric quantity of the terminal equipment is larger than a second electric quantity threshold value, determining that the target working mode is a second mode.

For example, when the power information characterizes that the power of the terminal device is less than or equal to 10% (10% is the first power threshold value), the target working mode to which the terminal device needs to be switched is the LPWUS mode; when the electric quantity information represents that the electric quantity of the terminal equipment is more than 10 percent (10 percent is a first electric quantity threshold value) and less than or equal to 30 percent (30 percent is a second electric quantity threshold value), the target working mode to which the terminal equipment needs to be switched is a first mode; when the electric quantity information represents that the electric quantity of the terminal equipment is more than 30%, the target working mode to which the terminal equipment needs to be switched is a second mode.

In the embodiment of the present application, only the above three operation modes are taken as examples, and the correspondence between the electric quantity information of the terminal device and the operation modes is described. It should be appreciated that the correspondence between the power information and the working mode may be determined according to actual requirements, which is not limited in the present application. For example, the terminal device may also support other operation modes, and correspond to different power intervals, etc.

S302, if the current working mode of the terminal equipment is different from the target working mode, the terminal equipment sends first indication information to the network equipment.

For example, when the terminal device detects that the current working mode is the first mode and the target working mode determined according to the electric quantity information is the LPWUS mode, the terminal device is characterized in that the terminal device needs to send first indication information to the network device to switch to the LPWUS mode, so that power consumption of the terminal device is saved and subsequent endurance time of the terminal device is prolonged. For another example, if the terminal device is currently in the LPWUS mode and the terminal device is being charged, when the charge is performed until the charge amount information is between the first charge amount threshold and the second charge amount threshold, the terminal device needs to switch to the first mode, and the terminal device needs to send first indication information to the network device to switch to the first mode, so as to enhance the network function of the terminal device and improve the user experience. Or if the terminal equipment is currently in the LPWUS mode and the terminal equipment is being charged, the terminal equipment is characterized in that the problem of low electric quantity does not need to be considered, and the first indication information can be directly sent to the network equipment to be switched to the second mode, so that the network function of the terminal equipment is enhanced, and the user experience is improved.

According to the method provided by the embodiment of the invention, through considering the electric quantity information of the terminal equipment and according to the corresponding relation between the electric quantity information and the target working mode, when the current working mode of the terminal equipment is different from the target working mode, the first indication information is actively sent to the network equipment to request to switch to the target working mode, so that the terminal equipment works with the power consumption more matched with the electric quantity information, the power consumption of the terminal equipment can be further reduced, the cruising ability of the terminal equipment is improved, or the power consumption of the terminal equipment is improved to enhance the functions of the terminal equipment, and the user experience is improved.

Optionally, the terminal device may also select whether to turn on the LPWUS mode according to actual requirements. For example, the LPWUS mode may be turned off in response to an operation with the user, and the target operation mode to which the first indication information request is switched does not include the LPWUS mode. Alternatively, the LPWUS mode may be turned on in response to an operation with the user, and the target operation mode to which the first indication information request is switched includes the LPWUS mode, and the like.
