This page describes SCCPCH or Secondary Common Control Physical Channel with respect to WCDMA/UMTS system.
The Secondary CCPCH is used to carry the FACH and PCH.
Channel coding- CRC, convolutional code
Symbol rate- 15/30/60/120/240/480/960 ksps
Modulation- QPSK
Spreading- predefined code broadcast on the BCH
Scrambling Gold sequence- 3.84Mcps, 10 ms periodic
Power control- not supported
Pilot symbol- include
TFCI bits- included/not include
