Method for performing wireless communication between user equipment and base station in a wireless communication system supporting first user equipment using single frequency band and second user equipment using multiple frequency bands

A method for performing a wireless communication between a User Equipment (UE) and a Base Station (BS) in a wireless communication system supporting a first UE using a single frequency band and a second UE using a plurality of frequency bands, to each of which Orthogonal Frequency Division Multiplexing (OFDM) is applied, the method comprising:

• being allocated one or more downlink component carriers for the second UE from the BS;
• and
• receiving the one or more downlink component carriers from the BS by the second UE,
• wherein the one or more downlink component carriers are cyclically shifted by different cyclic shift values and the cyclic shifting is performed by multiplying each of the one or more downlink component carriers by a linear phase having a different inclination.
