Abstract: A method for wireless communication between user equipments (UEs) and a base station in a wireless communication system that supports a first UE using a single band and a second UE using multiple bands is provided. In the method, UE receives, from the base station, resource allocation information including information regarding a downlink component carrier (CC) and an uplink CC allocated to the UE, receives the allocated downlink CC, and transmits the allocated uplink CC by applying a cell ID thereto. The allocated downlink CC is one of downlink CCs to which different cell IDs are applied, pairs of CCs are predefined by associating uplink CCs respectively with downlink CCs in order to support the first UE. When the allocated downlink and uplink CCs do not belong to the pairs of CCs, the applied cell ID is a cell ID of a downlink CC that is paired with the allocated uplink CC in the predefined pairs of CCs.

Abstract: A method for transmitting signals for interference randomization is disclosed. The method for transmitting signals includes spreading the transmission signals using a plurality of orthogonal codes and transmitting the transmission signals spread by the plurality of orthogonal codes by a spatial frequency block coding (SFBC) or spatial time block coding (STBC) scheme. Among the plurality of orthogonal codes, codes of which mutual interferences are equal to or greater than a predetermined threshold are grouped to the same group, and orthogonal codes belonging to different groups are used for the spreading of the signals which are transmitted at the same timing. Accordingly, it is possible to realize interference randomization.
