Description

Communication method, terminal, storage medium and program product Technical Field The present application relates to the field of mobile communications technologies, and in particular, to a communication method, a terminal, a storage medium, and a program product. Background Currently, with the rapid development of mobile communication networks, mobile communication services are increasing continuously, and in order to improve uplink coverage rate and uplink rate of the mobile communication networks, operators set a plurality of frequency bands to perform uplink transmission by high-power terminals. The high power terminal can perform uplink transmission with higher power in the frequency band. The terminal emits electromagnetic waves when transmitting uplink, and the influence of the electromagnetic waves on the human body can be represented by an electromagnetic wave absorption ratio (Specific Absorption Rate, SAR) value. The stronger the electromagnetic wave, the higher the SAR value, which means that the electromagnetic wave has a greater influence on the human body. When the transmission power of the terminal is high, the electromagnetic wave emitted by the terminal is also strong, that is, the SAR value of the electromagnetic wave emitted by the terminal is high, which may have adverse effects on the human body. Disclosure of Invention In view of this, the present application provides a communication method, a terminal, a storage medium, and a program product to reduce SAR values of electromagnetic waves transmitted by the terminal during uplink transmission. In a first aspect, an embodiment of the present application provides a communication method, applied to a terminal, where the method includes: And if the uplink scheduling rate of the terminal in the first detection time interval is greater than a threshold value and the transmission power is greater than the maximum transmission power, the terminal adjusts the transmission power of the terminal according to the information about the center frequency point of the adopted communication frequency band, wherein the first detection time interval is a continuous time interval taking the current moment as an interval end point. From the above, when the scheme provided by the embodiment of the present application is applied to communication, the terminal may adjust the transmission power, for example, reduce the transmission power, based on the information about the center frequency point of the adopted communication frequency band under the condition that the uplink scheduling rate is determined to be greater than the threshold value and the transmission power is determined to be greater than the maximum transmission power. After the terminal reduces the transmission power, the intensity of the transmitted electromagnetic wave is reduced, so that the SAR value of the electromagnetic wave is reduced, and the influence of the electromagnetic wave on a human body is reduced. In other words, in the scheme provided by the embodiment of the application, the condition that the terminal reduces the transmission power can be that the uplink scheduling rate is greater than the threshold value and the transmission power is greater than the maximum transmission power, and when the condition is met, the condition indicates that the frequency of uplink scheduling of the terminal in the first detection interval is higher and the transmission power is higher. In this case, the SAR value of the electromagnetic wave emitted by the terminal may be high. In this way, the terminal decreases the transmission power when it is determined that the above condition is satisfied, that is, when it is detected that the SAR value may be excessively high. In other words, when the terminal detects that the SAR is possibly too high, the terminal actively reduces the transmission power, so that the probability of exceeding the SAR value due to higher transmission power can be obviously reduced. In one embodiment of the present application, the total time length of the first detection time interval is longer than a set time length. In this embodiment, the total time length of the first detection time interval is longer than the set time length, which indicates that the uplink scheduling rate and the transmission power of the terminal in a longer continuous time period are both higher, and at this time, the probability that the SAR value of the electromagnetic wave transmitted by the terminal exceeds the standard is higher. Therefore, the terminal reduces the transmission power under the condition that the SAR value of the electromagnetic wave exceeds the standard, namely reduces the transmission power again under the condition that the SAR value exceeds the standard, reduces the probability that the transmission efficiency is low due to the fact that the transmission power is reduced when the SAR value does not exceed the standard, and simultaneously considers the transmission efficienc
