Abstract:
1. A method for providing a synchronization channel (SCH), the method comprising: allocating the SCH in a downlink (DL) frame by a base station, wherein the SCH comprises a Primary SCH (P-SCH) and a Secondary SCH (S-SCH), wherein the total time length occupied by the P-SCH and the S-SCH is equal to one OFDM symbol time length of a data channel, and wherein the S-SCH is located in front of the P-SCH in the DL frame, wherein the P-SCH is applied with frequency reuse one to maintain a multi-period time-domain structure in cell edge, and wherein the S-SCH is applied with frequency reuse N to mitigate interference among different cells, and wherein N is an integer larger than one; and transmitting SCH preambles via the synchronization channel (SCH) in a wireless OFDM/OFDMA system.
