A method for controlling uplink transmission power, performed by a base station, the method comprising: determining an uplink resource ratio of a user equipment, UE, in a preset high-power mode; determining, in response to the uplink resource ratio being greater than or equal to a preset uplink proportion threshold corresponding to the preset high-power mode, power adjustment information; and sending the uplink resource ratio and the power adjustment information to the UE; wherein the power adjustment information is configured to instruct the UE in the preset high-power mode to reduce uplink transmission power in transmitting uplink information according to the uplink resource ratio; wherein determining the uplink resource ratio of the UE in the preset high-power mode comprises: determining whether the UE supports a preset power adjustment function, the preset power adjustment function being configured to avoid exceeding a standard specific absorption rate, SAR, by adjusting the uplink transmission power in response to the uplink resource ratio exceeding the preset uplink proportion threshold corresponding to the preset high-power mode; and determining, in response to the UE supporting the preset power adjustment function, the uplink resource ratio according to a first uplink proportion threshold corresponding to the preset high-power mode, wherein the first uplink proportion threshold is an uplink proportion threshold corresponding to an upper limit value of SAR; wherein determining the uplink resource ratio according to the first uplink proportion threshold corresponding to the preset high-power mode comprises: determining a power margin according to maximum transmission power of the UE in the preset high-power mode; determining a configurable maximum uplink proportion based on the power margin; and determining an uplink proportion higher than the first uplink proportion threshold as the uplink resource ratio, wherein the uplink resource ratio does not exceed the maximum uplink proportion. determining an uplink resource ratio of a user equipment, UE, in a preset high-power mode; determining, in response to the uplink resource ratio being greater than or equal to a preset uplink proportion threshold corresponding to the preset high-power mode, power adjustment information; and sending the uplink resource ratio and the power adjustment information to the UE; wherein the power adjustment information is configured to instruct the UE in the preset high-power mode to reduce uplink transmission power in transmitting uplink information according to the uplink resource ratio; determining whether the UE supports a preset power adjustment function, the preset power adjustment function being configured to avoid exceeding a standard specific absorption rate, SAR, by adjusting the uplink transmission power in response to the uplink resource ratio exceeding the preset uplink proportion threshold corresponding to the preset high-power mode; and determining, in response to the UE supporting the preset power adjustment function, the uplink resource ratio according to a first uplink proportion threshold corresponding to the preset high-power mode, wherein the first uplink proportion threshold is an uplink proportion threshold corresponding to an upper limit value of SAR; wherein determining the uplink resource ratio according to the first uplink proportion threshold corresponding to the preset high-power mode comprises: determining a power margin according to maximum transmission power of the UE in the preset high-power mode; determining a configurable maximum uplink proportion based on the power margin; and determining an uplink proportion higher than the first uplink proportion threshold as the uplink resource ratio, wherein the uplink resource ratio does not exceed the maximum uplink proportion. determining a power margin according to maximum transmission power of the UE in the preset high-power mode; determining a configurable maximum uplink proportion based on the power margin; and determining an uplink proportion higher than the first uplink proportion threshold as the uplink resource ratio, wherein the uplink resource ratio does not exceed the maximum uplink proportion.
