Abstract
The invention varies the distribution of protective chips in DwPCH and UpPCH in TD-SCDMA system, and increases the protective chip numbers between SYNC_D and SYNC_UL so as to ensure the time interval between SYNC_UP and TS1. The architecture thereof increases the coverage area of TD-CDMA system, doesn't change the numbers of TD-SCDMA subframe, doesn't influence the receiving demodulation algorithm of UE and Node B and doesn't increase the process delay of UE and Node B.
