In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

For the convenience of understanding the embodiments of the present application, a communication system applied to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1A as an example. Fig. 1A shows a schematic diagram of a communication system suitable for the communication method of the embodiment of the present application. As shown in fig. 1A, the communication system 100 includes a network device 102 and a communication device 106, where the network device 102 may be configured with multiple antennas, and the terminal device may also be configured with multiple antennas. Optionally, the communication system may further include the network device 104, and the network device 104 may also be configured with multiple antennas.

It should be understood that network device 102 or network device 104 may also include a number of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, etc.).

The network device is a device with a wireless transceiving function or a chip that can be set in the device, and the device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), Access Point (AP) in wireless fidelity (WIFI) system, wireless relay Node, wireless backhaul Node, transmission point (TRP or TP), etc., and may also be 5G, such as NR, gbb in system, or, a transmission point (TRP or TP), one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, alternatively, it may also be a network node forming a gNB or a transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU).

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may also include a Radio Unit (RU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU implements the function of a Radio Resource Control (RRC) layer, a packet data convergence layer protocol (PDCP) layer, and the DU implements the function of a Radio Link Control (RLC), a Medium Access Control (MAC), and a Physical (PHY) layer. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PHCP layer signaling, may also be considered to be transmitted by the DU or by the DU + RU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

The communication device may also be referred to as a User Equipment (UE), an access terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal device, a mobile device, a user terminal device, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned driving (self), a wireless terminal device in remote medical (remote medical), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in city (city), a wireless terminal device in smart home (smart), and the like. The embodiments of the present application do not limit the application scenarios. For convenience of description, the communication terminal device and the chip that can be disposed on the communication terminal device are collectively referred to as a terminal device hereinafter.

In the communication system 100, the network device 102 and the network device 104 may each communicate with a plurality of terminal devices (e.g., the terminal device 106 shown in the figure). Network device 102 and network device 104 may communicate with any number of terminal devices similar to terminal device 106. It should be understood that the terminal device communicating with network device 102 and the terminal device communicating with network device 104 may be the same or different. The terminal device 106 shown in fig. 1A may communicate with both the network device 102 and the network device 104, but this only illustrates one possible scenario, and in some scenarios, the terminal device may communicate with only the network device 102 or the network device 104, which is not limited in this application.

It should be understood that fig. 1A is a simplified schematic diagram of an example for ease of understanding only, and that other network devices or other terminal devices may also be included in the communication system, which is not shown in fig. 1A.

The embodiment of the application provides a method for transmitting service data, and link adaptation, power control and the like are often important management functions in a communication system in order to improve system performance. In a communication network, at least one node sends signals to other nodes, and the purpose of power control is to enable the power of the signals sent by at least one node in the network to meet the requirements of the system when the signals reach other nodes.

Here, the node may refer to a base station, a user equipment, and the like. For example, power control may be such that the power of a signal transmitted by one user meets certain power requirements when it reaches another user. Alternatively, for example, the power control may be such that the power of the signal transmitted by the user, when arriving at the base station, meets the power requirements of the base station. Or, for example, the power control may be performed, so that the power requirement of the ue is met when the signal transmitted by the base station reaches the ue.

The power requirement in power control may refer to a power requirement for reaching a node, for example, if a signal is a useful signal for the node, the node has a requirement for the power of a received signal to meet a demodulation threshold, where the requirement is that the power of the received signal should not be too low, otherwise, the received signal cannot be correctly received and demodulated. Or, if the signal is a non-useful signal for the node, such as an interfering signal, the node has a requirement for the power of the received signal to meet an interference threshold, where the requirement is that the power of the received signal should not be too high, otherwise the signal causes strong interference to the useful signal of the node.

Power control may occur between one node and another, such as D2D scenario for a user equipment to another user equipment power to satisfy a certain signal to interference plus noise ratio (SINR); or between multiple nodes and one node, such as uplink in LTE, where power control is to let at least one ue in the network reach the power of the base station to meet the SINR requirement of the base station; it may also occur between multiple nodes, for example, in a Time Division Duplex (TDD) network system, there may exist uplink and downlink scheduling in the system (e.g., dynamic TDD technology in 5G network), and at this time, the power control may be used to relate the power requirements of multiple ues and multiple base stations in the network.

The power control is designed to control the signal transmission power of the nodes in the network so that the reception power of the signal meets the reception requirements. Here, the reception requirement may be the power requirement, SINR requirement, or the like described above, or a single-noise ratio (SNR) requirement. SNR, SINR, IoT (interference over thermal), RSRP (reference signal received power), received power of a signal, etc. may all be regarded as target parameters in the power control element, and these parameters are not completely equivalent but are interrelated. For example, the SINR and RSRP are not exactly equal, but with the same interference level, a higher RSRP means a better SINR for the signal. The power control in this context does not limit the target control parameters of the algorithm in practice.

The method for transmitting the service data is suitable for a communication system introducing a dual connection technology. The dual connectivity technique is carrier aggregation under the premise of non-ideal backhaul, which means that one terminal device can be simultaneously connected to two base stations connected through the non-ideal backhaul for data communication. A typical scenario is that one base station is a macro cell, and the other base station is a small cell. The macro cell and the small cell are connected via a standard X2 interface. Scheduling of multiple carriers in the carrier aggregation of R10 is completed by a scheduler; in the dual connectivity, since the schedulers of the macro cell and the small cell manage radio resources at the respective base stations, they need to coordinate with each other. This is to illustrate the essential difference between dual connectivity and carrier aggregation from a system architecture perspective. One advantage of dual connectivity techniques over carrier aggregation techniques is to allow macro and small cells to be out of synchronization in system time.

Fig. 1B is a dual-connected control plane architecture topology. Wherein 201 is MeNB, MeNB denotes macro cell, 202 is SeNB, SeNB denotes small cell, 203 is MME, and MME is a mobility control entity of the core network. The signalling connection between the terminal equipment, MeNB and MME203 is unchanged from the existing system at the time, i.e. one terminal equipment has only one radio resource control signalling (RRC) link and one S1 signalling link. The SeNB and MeNB are still connected via the X2 interface.

Carrier aggregation may be configured separately on the MeNB and SeNB in fig. 1B. To make a progressive differentiation, all configured serving carriers on the MeNB are called a Master Cell Group (MCG), and all configured serving carriers on the SeNB are called a Secondary Cell Group (SCG). The dual connection technology allows the terminal device to simultaneously and respectively establish connection with an mcg (master cell group) and an scg (sensory cell group), so that the throughput rate of a single user can be improved. In a dual connectivity scenario, the primary cell group may also be configured by more than one base station, and the secondary cell group may also be configured by more than one base station.

For the dual connectivity mode of LTE and LTE, Uplink Control Information (UCI) may be jointly transmitted through a PUCCH in the MCG and a PUCCH in the SCG. DC is because MCG and SCG are allowed to be asynchronous in system time, then, there is resource overlapping problem in the sub-frame of different cells under the scheduling of MeNB and SeNB, the resource overlapping refers to the time domain resource overlapping of MCG and SCG, the current protocol stipulates that MCG and SCG are respectively configured with maximum power P MeNB and P SeNB, the total power of each carrier in MCG can not exceed P MeNB, likewise, the total power of each carrier in SCG can not exceed P SeNB, and the sum of P MeNB and P SeNB can not exceed the maximum power P cmax of all carriers. The configuration power of each terminal device on the MeNB and SeNB on the network side is distributed through γ MCG and γ SCG, where γ MCG and γ SCG are percentage values, i.e. the power configuration value of each terminal device on each cell by the base station in the dual connectivity mode can be obtained by multiplying P cmax by γ MCG and P cmax by γ sCG.

Because the UE in the dual connectivity mode of LTE and LTE calculates P cmax _ MeNB and P cmax _ SeNB by using the maximum allowed transmit power P emax configured on the network side and the maximum allowed transmit power P powerclass of itself, then calculates P cmax _ MeNB and P cmax _ SeNB, and finally calculates P cmax _ dc by using the parameters γ MCG and γ SCG, multiplying γ MCG by P cmax and P cmax by γ sCG to obtain the power configuration value of the base station for each terminal device on each cell group in the dual connectivity mode.

For the dual connectivity mode of E-UTRAN and LTE (abbreviated as EN-DC mode), considering the evolution procedure of the network, currently, the default is that E-UTRAN is the main cell group, NR is the auxiliary cell group, and currently, the standard defines dynamic power sharing as a capability, where the terminal device type with the dynamic power sharing capability is the first type terminal device, and the terminal device type without corresponding capability is the second type terminal device, which can be understood here as that the second type terminal device can support semi-static power sharing. In the EN-DC mode, the primary cell group may also be NR and the secondary cell group may also be LTE.

In the following method embodiments, for convenience of description, only the main body of execution of each step is described as the terminal device.

The following describes in detail a transmission method of service data provided in an embodiment of the present application with reference to fig. 2 to 4.

Please refer to fig. 2, which is a flowchart illustrating a method for transmitting service data according to an embodiment of the present application. The present embodiment is exemplified by applying a service data transmission method to a terminal device. The service data transmission method may include the steps of:

s201, measuring the data throughput rate of the current data connection.

The data throughput rate indicates the data volume transmitted by the terminal device in unit time, the current data connection indicates the connection currently established by the terminal device for transmitting the service data, the terminal device establishes the current data connection through a serving cell, and the serving cell may be a 4G cell or a 5G cell. The terminal device may be registered to both the 4G cell and the 5G cell, or may be registered only to the 4G cell or the 5G cell. When the terminal equipment is registered in the 4G cell and the 5G cell at the same time, the terminal equipment is in a dual-connection mode, and at the moment, the terminal equipment can transmit service data through 4G data connection and 5G data connection at the same time; when the terminal equipment registers to the 4G cell or the 5G cell, the terminal equipment can only transmit service data through 4G data connection or 5G data connection, that is, the terminal equipment is in a single connection mode. The terminal equipment is in a dual-connection mode, and the current data connection comprises 4G data connection and 5G data connection; and the terminal equipment is in a single connection mode, and the current data connection is 4G data connection or 5G data connection. The terminal device may measure the data throughput rate of the current data connection before transmitting the traffic data. The 4G Data connection may also be referred to as a PDN (Public Data Network) connection, and the 5G Data connection may also be referred to as a PDU (Packet Data unit) session.

S202, determining that the data throughput rate is smaller than or equal to a throughput rate threshold value, and the current data connection is a 5G data connection.

The terminal device prestores or is configured with a throughput rate threshold, and the size of the throughput rate threshold may be determined according to actual needs, which is not limited in the embodiments of the present application. The terminal device determines whether the data throughput is less than or equal to a throughput threshold, and when the data throughput is less than the throughput threshold, it continues to determine whether the current data connection is a 5G data connection, and if so, executes S203.

S203, establishing a 4G data connection, and closing a 5G data connection.

The terminal equipment searches for a 4G service cell when the terminal equipment is in a single connection mode, establishes 4G data connection through the 4G service cell, and closes 5G data connection after the 4G data connection is successfully established. And when the terminal equipment is in the single connection mode, the terminal equipment keeps the 4G data connection unchanged, and closes the 5G data connection.

And S204, transmitting the service data through the 4G data connection.

The terminal device transmits the service data only through the 4G data connection, the transmission rate of the 4G system is smaller than that of the 5G system, but the power consumption of the 4G system is smaller than that of the 5G system, so that when the data throughput is smaller than or equal to the throughput threshold, the terminal device is only suitable for the 4G data connection to transmit the service data, the power consumption of the terminal device for transmitting the service data can be reduced, and meanwhile, the time delay of service data transmission cannot be increased.

According to the content, the terminal device measures the data throughput rate of the current data connection, when the data throughput rate is smaller than or equal to the throughput rate threshold value and the current data connection is 5G data connection, the terminal device establishes 4G connection, closes the 5G data connection, and transmits service data only through the 4G data connection, so that the problem of high power consumption caused by the fact that the terminal device transmits the service data through a 5G network in the related technology is solved; when the data throughput rate is low, the service data is transmitted through the 4G data network by using the special low-power-consumption 4G network, and meanwhile, the transmission delay of the service data is not increased.

Referring to fig. 3, another flow chart of a method for transmitting service data is provided in the present embodiment, where the method includes the following steps:

s301, receiving a measurement configuration message from the network equipment.

The measurement configuration message may be a message sent by the network device to the terminal device through a measConfig cell carried in the RRC connection configuration message, where the measurement configuration message includes: measurement objects, cell lists, reporting modes, measurement identities, time parameters, etc. The measured object represents the parameters that the terminal device needs to measure, such as: for intra-frequency and inter-frequency measurements, the measurement object is a single 4G carrier frequency or 5G carrier frequency. For the measurement between different RATs, the measurement object is a single UTRA measurement. For GERAN (GSM EDGE radio access Network, GSM/EDGE wireless communication Network) measurement between different RATs (radio access technologies ), a measurement object is a GERAN bearer frequency set. The cell list represents one or more cells which the terminal equipment needs to measure; the reporting mode represents a mode of reporting a measurement report to a network device, for example: and reporting periodically or reporting by condition triggering. The measurement identifier indicates an identifier of the current measurement. The time parameter represents a parameter related to the measured time.

S302, cell measurement is carried out based on the measurement configuration message to obtain a measurement report.

The terminal device performs cell measurement according to the measurement configuration message, where the cell may be a serving cell or an adjacent cell, and generates a measurement report according to a cell measurement result, where the measurement report includes a data throughput rate of a current data connection established in the serving cell.

And S303, determining the data throughput rate of the current data connection according to the measurement report.

The data throughput rate represents the data volume transmitted by the terminal in unit time, the current data connection represents the connection for transmitting service data, which is currently connected by the terminal device, the terminal device establishes the current data connection through a serving cell, the serving cell may be a 4G cell or a 5G cell, the data connection established by the terminal device through the 4G cell is the 4G data connection, and the data connection established by the terminal device through the 5G cell is the 5G data connection. The terminal device may be registered to both the 4G cell and the 5G cell, or may be registered only to the 4G cell or the 5G cell. When the terminal equipment is registered in the 4G cell and the 5G cell at the same time, the terminal equipment is in a dual-connection mode, and at the moment, the terminal equipment can transmit service data through 4G data connection and 5G data connection at the same time; when the terminal device registers to the 4G cell or the 5G cell, the terminal device is in the single connection mode, and at this time, the terminal device transmits service data only through the 4G data connection or the 5G data connection. The terminal device may measure the data throughput rate of the current data connection before transmitting the traffic data. In the embodiment of the present application, the 4G data connection may also be referred to as PDN connection, and the 5G data connection may also be referred to as PDU session.

The terminal equipment can search at least one 4G cell and at least one 5G cell simultaneously after being started, select the 4G cell with the best signal quality in the at least one cell as a 4G service cell, select the 5G cell with the best signal quality in the at least one 5G cell as a 5G service cell, establish the 5G service cell through the 5G service cell, the terminal equipment does not initiate the establishment process of 4G data connection in the 4G cell, and the terminal equipment only resides in the 4G service cell, so that the time for searching and selecting the 4G service cell when establishing the 4G data connection can be reduced.

S304, judging whether the data throughput rate is less than or equal to the throughput rate threshold value.

The terminal device prestores or is configured with a throughput rate threshold, and the terminal device determines whether the data throughput rate of the current data connection is less than or equal to the throughput rate threshold, if so, executes S305, and if not, executes S313.

For example: the throughput threshold is 100 mbytes/sec, the terminal device measures the throughput of the current data connection to be 80 mbytes/sec, and the terminal device determines that the data throughput of the current data connection is less than the throughput threshold, and S305 is executed.

Another example is: the throughput threshold is 100 mbytes/sec, the terminal device measures the data throughput rate of the current data connection to be 150 mbytes/sec, the terminal device determines that the data throughput of the current data connection is greater than the throughput rate threshold, and S313 is executed.

S305, judging whether the current data connection is 5G data connection.

Wherein, when the terminal device is in the single connection mode, the terminal device judges whether the current data connection is 5G data connection, if yes, S306 is executed; if not, go to S312.

S306, searching at least one 4G cell.

The terminal equipment searches for the 4G cell and searches for at least one 4G cell of the 4G on the 4G frequency band.

Referring to fig. 5, a schematic structural diagram of a terminal device according to an embodiment of the present invention is shown, where the terminal device may be used to implement the transmission method of service data in the foregoing embodiment. Specifically, the method comprises the following steps:

the memory 503 may be used to store software programs and modules, and the processor 500 executes various functional applications and data processing by operating the software programs and modules stored in the memory 503. The memory 503 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device, and the like. Further, the memory 503 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. Accordingly, the memory 503 may also include a memory controller to provide the processor 500 and the input unit 505 access to the memory 503.

The input unit 505 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 505 may comprise a touch sensitive surface 506 (e.g., a touch screen, a touch pad, or a touch frame). The touch-sensitive surface 506, also referred to as a touch screen or a touch pad, may collect touch operations by a user on or near the touch-sensitive surface 506 (e.g., operations by a user on or near the touch-sensitive surface 506 using a finger, a stylus, or any other suitable object or attachment), and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 506 may comprise both touch sensing devices and touch controllers. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 500, and can receive and execute commands sent by the processor 500. Additionally, touch sensitive surface 506 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves.

The Display unit 513 may include a Display panel 514, and optionally, the Display panel 514 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 506 may overlay the display panel 514, and when a touch operation is detected on or near the touch-sensitive surface 506, the touch operation is transmitted to the processor 500 to determine the type of touch event, and then the processor 500 provides a corresponding visual output on the display panel 514 according to the type of touch event. Although in FIG. 5, touch-sensitive surface 506 and display panel 514 are shown as two separate components to implement input and output functions, in some embodiments, touch-sensitive surface 506 may be integrated with display panel 514 to implement input and output functions.

The processor 500 is a control center of the terminal device, connects various parts of the entire terminal device by using various interfaces and lines, and performs various functions of the terminal device and processes data by running or executing software programs and/or modules stored in the memory 503 and calling data stored in the memory 503, thereby performing overall monitoring of the terminal device. Optionally, processor 500 may include one or more processing cores; the processor 500 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 500.
