Abstract: The disclosure provides a communication method, a base station, a user equipment, and a storage medium in a communication system supporting a carrier aggregation (CA). The method comprises identifying ratio information for a plurality of carriers for a user equipment (UE) from at least one candidate ratio information based on a total carrier transmission capacity of the plurality of carriers. The method comprises determining a transmit power for each carrier based on the target power allocation ratio information. The method comprises receiving, from the UE, uplink signals according to the transmit power for each carrier. The ratio information for the plurality of carriers includes a power allocation ratio for each carrier. The total carrier transmission capacity of the plurality of carriers comprises a sum of transport block sizes of individual carriers in the plurality of carriers. The above method performed by the base station or UE can be performed using an artificial intelligence model.
