Description

Method and device for adjusting data transmission mode

Technical field

This document relates to, but is not limited to, wireless communication technology, and more particularly to a method and apparatus for adjusting data transmission methods.

Background technique

With the continuous evolution and development of mobile communication technology, while improving the wireless data transmission speed, how to ensure the link transmission quality is the main factor to be considered when transmitting data. In related technologies, transmission power control and transmission rate control can be adopted. A transmission quality guarantee is achieved; wherein the transmit power control compensates for fluctuations and differences in instantaneous channel conditions by dynamically adjusting the transmit power of the wireless link, and maintains an approximately fixed signal-to-noise ratio at the receiving end to ensure data transmission, thus The error rate of data transmission can be controlled; the transmission power control method increases the transmission power of the transmitter when the wireless link is poor; and reduces the transmission power when the wireless link is good. The transmission rate control method controls the radio link data rate by adjusting the modulation mode and/or the channel coding rate; when the radio link is good, the receiver has a high signal-to-noise ratio and is suitable for high-order modulation (hexadecimal orthogonal) Amplitude modulation (256QAM), octal quadrature amplitude modulation (64QAM), etc., and a higher coding rate mode; when the radio link is poor, the low-order modulation mode and the lower coding rate mode are selected.

Compared with the fourth-generation mobile communication technology (4G), the throughput of 5G networks has been greatly improved; for example, 3 carrier aggregation (3CA), 4 antennas with multiple input and output (4X4 MIMO), 256QAM, etc. The throughput of the downlink can be increased to 1 GHz (G); as the processing complexity and overhead of the system increase, the terminal consumes more power and heat, and data transmission is not guaranteed.

At present, Long Term Evolution (LTE) adopts Adaptive Modulation and Coding (AMC) technology to adjust the modulation mode and coding rate of wireless link transmission to ensure the transmission quality of the link. Table 1, Table 2, and Table 3 are examples of correspondence between channel quality indication (CQI) index (index), modulation rate, code rate, and efficiency in the related art; Both interference and fading are time-varying. By dynamically adjusting the forward and reverse transmit power and maintaining a certain signal-to-noise ratio at the receiving end, the transmission quality of the link can be guaranteed. When the channel quality is poor, the transmit power is increased. When the channel quality is good, the transmission power is reduced. However, when the status of the wireless link is complicated and the link status changes greatly and rapidly, the frequency of the terminal adjustment increases, the system overhead increases, and the power consumption and heat generation of the terminal are further aggravated, which affects the normal use of the terminal.

The method of the embodiments of the present disclosure is described in detail below by way of application examples, and the application examples are only used to illustrate the disclosure, and are not intended to limit the scope of the disclosure.

Application example

This application example is illustrated by using a 5G network for data downloading by a terminal. FIG. 3 is a flowchart of a method for applying the example of the present disclosure. As shown in FIG. 3, the method includes:

Step 300: The terminal enables the 5G network and performs data downloading.

Step 301: Detecting a temperature of the terminal battery;

In this application example, the terminal main chip collects the temperature from the battery end, loads the control information into the uplink control information (UCI), and notifies the system through the PUCCH.

Step 302: Obtain a CQI index corresponding to the detected temperature of the terminal battery according to a preset index adjustment policy.

Optionally, in this application example, the index adjustment policy includes:

When the detected temperature of the terminal battery is greater than the first preset value, and the duration is greater than the first preset duration, the first difference obtained by subtracting the detected temperature of the terminal battery from the first preset value is calculated; The corresponding relationship between the first difference and the CQI index value adjustment is performed, and the CQI index is reduced and adjusted by the current value;

When the detected temperature of the terminal battery is greater than the second preset value, the CQI index is directly adjusted from the current value to be less than or equal to the second preset index value;

If the detected temperature of the terminal battery is less than the third preset value, and the duration is greater than the third preset duration, the CQI index is directly adjusted from the current value to be greater than or equal to the third preset index value;

When the detected temperature of the terminal battery is less than the fourth preset value, and the duration is greater than the fourth preset duration, calculating a fourth difference obtained by subtracting the fourth preset value from the acquired temperature; according to the preset fourth The correspondence between the difference and the CQI index value adjustment increases the CQI index by the current value.

The following is an example of the contents of the index adjustment strategy by specific values, including:

When the battery temperature of the terminal reaches 50 degrees and remains at 50 degrees or more for more than one minute, the CQI index is reduced by the current value; for example, the battery temperature of the terminal starts from 50 degrees, and each time it rises, the CQI index Make a minus one adjustment;

When the temperature of the terminal battery is greater than 53 degrees, the value of the CQI index is directly adjusted: the debugging mode corresponding to the CQI index is the value of the modulation mode of the 4G network, so that the battery temperature drops. Here, when the modulation mode corresponding to the CQI index is the modulation mode of the 4G network, the CQI index of the 4G network can be used to control the modulation mode, and the CQI index of the 4G network has a certain correspondence with the CQI index of the 5G network, and the terminal works at 4G.

Obtaining a report of the CQI index; when the obtained first preset numerical sub-CQI index report, the probability that the first preset interval is greater than the first preset percentage, the setting terminal determines a corresponding in the first preset interval The CQI index of the temperature information; when the terminal performs the adjustment of the CQI index in the first preset interval, when the acquired second predetermined value is reported in the CQI index, the probability of falling in the second preset interval is greater than When the second preset percentage is set, the setting terminal determines the CQI index according to the index adjustment policy.

The following is an example of obtaining the post-reporting processing of the CQI index by an example: if the CQI index has 10 reports 10 times, the CQI index falls within the interval of 1 to 11. The terminal receives the control information, and the determined value of the CQI index is 1 to 11; when the 10 times of the CQI index value falls to 12 to 15 times, the value of the CQI index is obtained according to the index adjustment policy.
