Description
Technical Field
The present disclosure relates to, but not limited to, wireless communication technologies, and more particularly, to a method and apparatus for adjusting a data transmission scheme.
Background
With the continuous evolution and development of mobile communication technology, how to ensure the link transmission quality is a main factor to be considered when data transmission is carried out while the wireless data transmission speed is improved; in the related art, the transmission quality can be guaranteed by controlling the transmission power and the transmission rate; the transmission power control compensates the fluctuation and difference of instantaneous channel conditions by dynamically adjusting the transmission power of a wireless link, and maintains an approximately fixed signal-to-noise ratio at a receiving end to ensure data transmission, so that the error rate of data transmission can be controlled; the transmission power control method improves the transmission power of the transmitter when the wireless link is poor; when the wireless link is good, the transmission power is reduced. The transmission rate control method controls the data rate of a wireless link by adjusting a modulation mode and/or a channel coding rate; when a wireless link is good, the receiver has high signal-to-noise ratio and is suitable for adopting a high-order modulation mode (16-system quadrature amplitude modulation (256QAM), 8-system quadrature amplitude modulation (64QAM) and the like) and a higher coding rate mode; when the wireless link is poor, a low-order modulation mode and a lower coding rate mode are selected.
Compared with the fourth generation mobile communication technology (4G), the throughput of the 5G network is greatly improved; for example, the throughput can be improved to 1 gigabit (G) in a downlink realized by using technologies such as 3 carrier aggregation (3CA), 4-antenna multiple input and output (4X4MIMO) for uplink and downlink, 256QAM, and the like; with the increase of the processing complexity and the overhead of the system, the problems of power consumption and heating of the terminal are more serious, and data transmission cannot be guaranteed.
Currently, Long Term Evolution (LTE) adopts Adaptive Modulation and Coding (AMC) technology to adjust the Modulation scheme and coding rate of wireless link transmission, so as to ensure the transmission quality of the link. Table 1, table 2, and table 3 show examples of correspondence between a Channel Quality Indicator (CQI) index and a modulation scheme (modulation), a code rate (code rate), and an efficiency (efficiency) in the related art; because the interference and fading in the wireless channel are time-varying, the transmission quality of the link can be ensured by dynamically adjusting the forward and reverse transmitting power and maintaining a certain signal-to-noise ratio of the receiving end; when the channel quality is poor, the transmitting power is increased; when the channel quality is better, the transmit power is reduced. However, when the wireless link status is complex and the link status changes greatly and quickly, the adjustment frequency of the terminal increases, the system overhead increases, the power consumption and heating problems of the terminal will be further aggravated, and the normal use of the terminal is affected.

9. The apparatus according to claim 6, wherein the determining unit is specifically configured to:
calculating a fourth difference value obtained by subtracting the fourth preset value from the obtained temperature when the obtained temperature is less than a fourth preset value and the duration is longer than a fourth preset time;
and increasing and adjusting the CQI index from the current value according to the corresponding relation between the preset fourth difference value and the adjustment of the CQI index value.
10. The apparatus according to any one of claims 6 to 9, further comprising a report adjustment unit configured to:
obtaining a report of the CQI index;
when the probability of falling in a first preset interval in the obtained reports of the CQI indexes for the first preset value is greater than a first preset percentage, the setting terminal determines a CQI index corresponding to the temperature information in the first preset interval;
when the setting terminal adjusts the CQI index in the first preset interval, and when the probability of falling in the second preset interval in the report of the CQI index for the second preset numerical time is greater than a second preset percentage, the setting terminal determines the CQI index according to the index adjustment strategy.
11. A computer storage medium having computer-executable instructions stored therein for performing the method of adjusting a data transmission manner of any one of claims 1 to 5.
12. A terminal, comprising: a memory and a processor; wherein,
the processor is configured to execute program instructions in the memory;
the program instructions read on the processor to perform the following operations:
acquiring the temperature of a terminal;
obtaining a Channel Quality Indication (CQI) index corresponding to the obtained temperature according to a preset index adjustment strategy;
and setting the data transmission mode of the terminal according to the obtained CQI index.
