Abstract
A method for processing multiple Component Carriers (CCs) to be aggregated for transmission is provided in the present invention, the method comprising the steps of: acquiring a time domain signal of each of the multiple CCs; applying multiple fixed phase rotations respectively to the acquired time domain signal by utilizing phase rotation values in a set of phase rotations, so as to obtain multiple phase rotation versions of each CC; randomly selecting one of the multiple phase rotation versions of each CC to respectively constitute multiple candidate transmission groups, and acquiring an amplitude sum of the phase rotation versions for each of the multiple candidate transmission groups; determining a candidate transmission group having the minimum amplitude sum; and transmitting multiple phase rotation versions in the determined candidate transmission group having the minimum amplitude sum. The present invention substantively provides a general solution capable of minimizing CM/PAPR of aggregated CCs for UL and DL.
