wcdma umts channel physical communication

This page describes the PCCPCH or Primary Common Control Physical Channel with respect to a WCDMA/UMTS system. The Primary CCPCH is a fixed-rate (30 kbps, SF=256) downlink physical channel used to carry the BCH transport channel.

Key characteristics of the PCCPCH:

Channel coding: CRC, convolutional code
Symbol rate: 30 ksps
Spreading factor: 256
Modulation: QPSK
Spreading: predefined code (Cch,256,1)
Scrambling: Gold sequence - 3.84 Mcps, 10 ms periodic, primary scrambling code of the sector
Power control: Not supported
Pilot symbol: Included
TFCI bits: Not included
