摘要： Even when communication is performed independently in each CC (Component Carrier), the occurrence of an error in communication is prevented. Provided is a wireless communication system in which a wireless transmission apparatus and a wireless reception apparatus communicate with each other using a plurality of system frequency bands, wherein the wireless transmission apparatus performs transmission power control on transmission data in each of the system frequency bands, and furthermore, a maximum transmission power which can be transmitted in each of the system frequency bands can be controlled so as to be different from each other. Priorities are set on each of the system frequency bands, and transmission powers of the system frequency bands are determined in descending order of the priorities.
