Method for transmitting and receiving signals using multi-band radio frequencies

摘要

A method for transmitting and receiving signals using multi-band Radio Frequencies (RFs) is provided. The method includes transmitting/receiving control information identifying a subsidiary carrier frequency band for a user equipment via a primary carrier frequency band of the user equipment, wherein the control information includes information of a second ID assigned to a first ID of the subsidiary carrier frequency band among a plurality of first IDs, the first ID identifying the subsidiary carrier frequency band in the physical layer and the second ID identifying the subsidiary carrier frequency band in the specific layer.
