Hereinafter, the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems will be described in detail through the embodiments and the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic flowchart of a transmission rate control method provided by an embodiment of the application. As shown in Fig. 2, the transmission rate control method includes the following steps:

S201. In the case of determining to start limiting the uplink transmission rate, the terminal adjusts the preset transmission power to obtain the first transmission power; the power value of the first transmission power is less than the power value of the preset transmission power; the terminal is in dual connection mode, and is in dual connection mode. In the mode, the terminal communicates with both the first base station and the second base station; the first base station is the secondary base station; the second base station is the main base station.

The transmission rate control method provided in the embodiment of the present application is applicable to a scenario where a terminal configured with an ENDC function performs uplink data transmission.

In the embodiment of the present application, the terminal is in a dual connection mode, and in the dual connection mode, the terminal communicates with both the first base station and the second base station. In an optional implementation manner, the first base station is a secondary base station, and the second base station is a primary base station. The secondary base station is responsible for transmitting data, and the primary base station is mainly responsible for transmitting signaling. The second base station forms a dual-connection architecture, refer to FIG. 1.

In the embodiment of the present application, the dual connection mode is, for example, the EN-DC mode, or the NGEN-DC mode, or the NE-DC mode. Taking the EN-DC mode as an example, the first base station is an NR base station (i.e. gNB), the second base station is an LTE base station (i.e. eNB), and the terminal communicates with the NR base station and the LTE base station at the same time. Compared with the terminal in the single connection mode that needs to communicate with a base station (such as an LTE base station or an NR base station), the terminal in the dual connection mode consumes more power. For this reason, the embodiment of the present application limits the transmission rate of the terminal to save the power consumption of the terminal in the dual connection mode.

Figure 3 is a structural diagram of the communication module of the terminal in the dual connection mode. As shown in Figure 3, in order for the terminal to communicate with two base stations at the same time, it needs to have two sets of communication modules, and the two sets of communication modules correspond to two base stations. Among them, the first modem module (modem) and the first radio frequency path (including the first radio frequency circuit and the first radio frequency antenna) form a first set of communication modules, and the first set of communication modules corresponds to the first base station. The second modem module (modem) and the second radio frequency path (including the second radio frequency circuit and the second radio frequency antenna) form a second set of communication modules, and the second set of communication modules corresponds to the second base station. In an example, the first modem is a 5G modem, the second modem is a 4G modem, the first radio frequency circuit is 5G RF, and the second radio frequency circuit is 4G RF. In the dual connection mode, the first communication module and the second communication module work at the same time.

In an example, the terminal first establishes a connection with the second base station, and then establishes a connection with the first base station. For example: when the terminal is connected to the second base station, a control instruction sent by the first base station is received, and the control instruction is used to trigger the activation of the communication function corresponding to the first base station; the terminal responds to the control instruction To establish a connection with the first base station.

In the embodiment of the present application, after the connection between the terminal and the first base station is established, the terminal can communicate with the first base station. It should be noted that the connection described in the embodiments of the present application refers to access. After the terminal turns on the communication function corresponding to the first base station, it needs to adjust various parameters of the terminal according to the actual situation, so as to achieve the best compromise between performance and power consumption, so that the user can get more experience. Further, the embodiment of the present application adjusts the uplink rate of the terminal to save power consumption of the terminal.

Taking the communication function corresponding to the first base station as the 5G function as an example, referring to Figure 4, Figure 4 is a schematic diagram of the terminal turning on the smart 5G. Here, turning on the smart 5G means optimizing the 5G function. Specifically, the terminal uses In the 5G function, various parameters of the terminal (such as uplink transmit power) can be adjusted according to the actual situation. As shown in Figure 4, the terminal turning on smart 5G includes the following processes:

1. The terminal judges whether it has received an operation to turn on the smart 5G.

Here, the terminal displays a user interface, and the user interface includes an option to turn on the smart 5G, and the user can trigger an operation to select the option corresponding to the smart 5G, thereby turning on the smart 5G. Here, the user's operation may be a touch operation, a key operation, a voice operation, a gesture operation, or the like.

2. If the operation of turning on the smart 5G is received, the 5G function is optimized.

Here, the optimization of the 5G function includes at least: limiting the 5G uplink transmission rate of the terminal to save the power consumption of the terminal.

3. If the control instruction to turn on the 5G function is not received, the 5G function will not be optimized.

In an application scenario, the terminal detects the signal quality of the first network where the first base station is located; when the signal quality of the first network is less than or equal to the target signal quality, the terminal turns on the function of limiting the uplink transmission rate; In this case, the terminal adjusts the transmit power of the Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel). It should be noted that the uplink transmission rate here refers to the uplink transmission rate corresponding to the first base station. Taking the first base station as a 5G base station as an example, the uplink transmission rate refers to the 5G uplink transmission rate.

In actual application, the signal quality of the first network may be at least one of the following:

Received signal strength indicator (RSSI);

Reference signal received power (RSRP);

Reference signal reception quality (RSRQ);

Signal to interference plus noise ratio (SINR).

Of course, in actual applications, the signal quality of the first network may also be other parameters that can characterize the signal quality of the network, which is not limited in the embodiment of the present application.

In an optional implementation manner, when the signal quality of the first network is greater than the target signal quality, the terminal turns off to limit the uplink transmission rate. In this case, the uplink transmission rate of the terminal is restored to the normal situation (that is, the transmission power of the PUSCH is not adjusted).

In an application scenario, the terminal detects the temperature of the terminal; when the temperature of the terminal is greater than or equal to the target threshold, the terminal opens the function of limiting the uplink transmission rate. When the uplink transmission rate starts to be limited, the terminal performs the PUSCH transmission power Adjustment. It should be noted that the uplink transmission rate here refers to the uplink transmission rate corresponding to the first base station. Taking the first base station as a 5G base station as an example, the uplink transmission rate refers to the 5G uplink transmission rate.

Exemplarily, the temperature of the terminal may be reflected by the temperature of a certain piece of hardware of the terminal or the average temperature of certain pieces of hardware, such as the temperature of the processor and the temperature of the memory.

In an optional implementation manner, when the temperature of the terminal is less than the target threshold, the terminal turns off the function of limiting the uplink transmission rate. In this case, the uplink transmission rate of the terminal is restored to the normal situation (that is, the transmission power of the PUSCH is not adjusted).

In an application scenario, the terminal detects the status information of the terminal; when the status information of the terminal is in the off-screen state, the terminal turns on the function of limiting the uplink transmission rate; or, when the state information of the terminal is in the sleep state, the terminal turns on to display the uplink In the transmission rate function, the terminal adjusts the transmission power of the PUSCH when the uplink transmission rate starts to be limited. It should be noted that the uplink transmission rate here refers to the uplink transmission rate corresponding to the first base station. Taking the first base station as a 5G base station as an example, the uplink transmission rate refers to the 5G uplink transmission rate.

In an alternative embodiment, when the status information of the terminal is changed to the bright screen state, the terminal turns off the function of limiting the uplink transmission rate, or when the state information of the terminal is changed to the working state, the terminal turns off the function of limiting the uplink transmission rate . In this case, the uplink transmission rate of the terminal is restored to the normal situation (that is, the transmission power of the PUSCH is not adjusted).

In an application scenario, the terminal detects the network congestion state between the terminal and the second base station; in the case that the network congestion state between the terminal and the second base station is less than the congestion threshold, the terminal turns on the function of limiting the uplink transmission rate, and starts to limit the uplink transmission rate. In the case of the transmission rate, the terminal adjusts the transmission power of the PUSCH. It should be noted that the uplink transmission rate here refers to the uplink transmission rate corresponding to the first base station. Taking the first base station as a 5G base station as an example, the uplink transmission rate refers to the 5G uplink transmission rate.

In an optional implementation manner, when the network congestion state between the terminal and the second base station is greater than or equal to the congestion threshold, the terminal turns off the function of limiting the uplink transmission rate. In this case, the uplink transmission rate of the terminal is restored to the normal situation (that is, the transmission power of the PUSCH is not adjusted).

Specifically, the terminal obtains the preset transmission power; then, the value of the preset transmission power is reduced to obtain the first transmission power.

In the embodiment of the present application, the terminal sets an uplink transmission power adjustment interface, and the terminal sets the maximum uplink transmission power or sets the uplink transmission power offset value by calling the interface, thereby realizing the function of adjusting the preset transmission power.

S202. Use the first transmit power to send uplink data to the first base station.

After the terminal adjusts the preset transmission power to obtain the first transmission power, the terminal uses the first transmission power to send uplink data to the first base station.

In the embodiment of the present application, the terminal carries the uplink data in the physical uplink shared channel PUSCH, and transmits the PUSCH with the first transmission power.

In the embodiment of the present application, the terminal adjusts the preset transmission power of the PUSCH to the first transmission power. At this time, the terminal uses the first transmission power to transmit uplink data to the first base station in the PUSCH.

Specifically, PUSCH uses one or more antennas for uplink transmission. The process of sending uplink data and uplink control signaling on PUSCH is: uplink data is transmitted in the form of transport block (TB), and TB undergoes cyclic redundancy calibration. CRC attachment, code block segmentation and sub-block CRC attachment, coding, rate matching, code block concatenation and coding After CQI/PMI multiplexes uplink data and uplink control signaling, and finally multiplexes the encoded ACK/NACK information, RI information and data together through channel interleaving to form a codeword stream. Scrambling, modulation, and mapping of codeword streams to layers map the above-mentioned data and control information to each transport layer for transmission.

In an optional implementation manner, the terminal may also reduce the uplink transmission rate by reducing the transmission rate of uplink data sent by the application layer to the first modem. Here, the application layer may refer to a system application layer or a third-party application layer, such as an application layer corresponding to a video application, an application layer corresponding to a chat software application, and so on. The uplink data is sent by the application layer to the first modem, and the first modem sends the uplink data to the first base station through the first radio frequency path. By reducing the transmission rate of the uplink data sent by the application layer to the first modem, the uplink transmission rate of the terminal can be reduced.

Exemplarily, as shown in Figure 5, for a terminal configured with an ENDC function, the terminal transmits PUSCH at normal transmission power according to network instructions. When the terminal determines that 5G needs to be suppressed, the terminal reduces the transmission power to the first transmission. Power, and send the PUSCH with the first transmit power.
