Claim Text:
1. A method of transmitting a synchronization signal in a carrier aggregation system, the method comprising: transmitting synchronization signal configuration information for a secondary component carrier (SCC), wherein the SCC is an extended component carrier used by a user equipment (UE) in addition to a primary component carrier (PCC), which is a component carrier used by the UE to establish an initial connection with a base station, wherein the synchronization signal configuration information of the SCC is transmitted through the PCC, and wherein the synchronization signal configuration information includes at least one of synchronization signal bandwidth, a synchronization signal transmission time and a synchronization signal transmission frequency hopping pattern; and transmitting the synchronization signal of the SCC through the SCC, wherein the synchronization signal of the SCC is determined according to the synchronization signal configuration information transmitted through the PCC, and wherein a first synchronization signal transmitted in the PCC includes a primary synchronization signal (PSS) having a sequence length of 63 and a secondary synchronization signal (SSS) having a sequence length of 31, and wherein a second synchronization signal transmitted in the SCC consists of only any one of the PSS and the SSS.
