Patent ID: 8406218

Claim:
A method of generating a forward link frame in a communication system, the method comprising: generating first synchronization channels including a first cell group information; generating second synchronization channels including a second cell group information; and generating the forward link frame including the first synchronization channels and the second synchronization channels, wherein the forward link frame further includes a plurality of sync blocks, and each of the first synchronization channels and each of the second synchronization channels are disposed on two adjacent symbols in each of the sync blocks, wherein a cell identity is specified by a combination of the first cell group information and the second cell group information, wherein each of first synchronization sequences that are respectively included in the first synchronization channels corresponds to the first cell group information, and a set of second synchronization sequences that are respectively included the second synchronization channels corresponds to the second cell group information, and wherein the sync block corresponds to a repetition cycle of the first synchronization channels.
