Title:

Document Type and Number:
WIPO Patent Application WO/2008/052406
Kind Code:
A1
Abstract:
This invention provides a method for sending synchronization channel (SCH) in
a time division duplex (TDD) system based on orthogonal frequency division multiplexing
(OFDM). It includes following steps: sending primary SCH (P-SCH) in DwPTS, sending
secondary SCH (S-SCH) utilizing the last OFDM symbol in TS0, sending the cyclic
suffix (CS) of the S-SCH symbol in the time interval between S-SCH and P-SCH. The
time span of CS is determined according to the length of the cyclic prefix (CP)
of OFDM symbols, so the time in TS0 which is not used to send CS is invariable when
different CP is used.
