Abstract:
One embodiment of the present specification relates to a method for reducing transmission power. The method for reducing transmission power can comprise the steps of: determining whether set carrier aggregation (CA) corresponds to intra-band non-contiguous CA when the CA is set; determining transmission power by applying maximum power reduction (MPR) when the set CA corresponds to intra-band non-contiguous CA; and reducing power by applying additional MPR to the determined transmission power in order to protect adjacent bands when non-contiguous carriers belong to a specific band.
