Patent ID: 8831119

Claim:
A method of transmitting a synchronization signal in a multi-node system including a plurality of nodes and a base station for controlling the plurality of node, the method comprising: generating a synchronization signal sequence; mapping the generated synchronization signal sequence to a resource element; and transmitting the mapped synchronization signal sequence to a user equipment via at least one node among the plurality of nodes, wherein the synchronization signal sequence is generated based on an identifier (ID) of a transmission node for transmitting the synchronization signal sequence, and wherein the synchronization signal sequence is generated by scrambling a sequence generated using a cell ID group N ID (1) or an ID N ID (2) included in the cell ID group, which are seed numbers constituting an ID of a cell controlled by the base station, by the use of a sequence generated using a seed number N ID (3) for determining the ID of the transmission node.
