Communication method, base station, user equipment and storage medium

A method performed by a base station supporting a carrier aggregation (CA), the method comprising:

• identifying transport block sizes (TBSs) based on candidate power allocation ratios for a plurality of carriers of the CA;
• identifying a power allocation ratio corresponding to a maximum TBS of the TBSs, from at least one candidate ratio information based on a total carrier transmission capacity of the plurality of carriers
• determining transmit powers for the plurality of carriers based on the power allocation ratio;
• transmitting, to a user equipment (UE), control information indicating the transmit powers for the plurality of carers;
• and
• receiving, from the UE, uplink signals according to the transmit powers for each the plurality of carriers.

A non-transitory computer-readable storage medium having stored thereon program instructions, the instructions, when executed by a processor, perform operations including:

• identifying transport block sizes (TBSs) based on candidate power allocation ratios for a plurality of carriers of a carrier aggregation (CA);
• identifying a power allocation ratio corresponding to a maximum TBS of the TBSs, from among the candidate power allocation ratios;
• determining transmit powers for the plurality of carriers based on the power allocation ratio;
• transmitting, to a user equipment (UE), control information indicating the transmit powers for the plurality of carriers;
• and
• receiving, from the UE, uplink signals according to the transmit powers for the plurality of carriers.
