Channels of the Code Domain Channel Table and their usage
The channel assignment table contains the following (data) channels:
• CPICH
The common pilot channel is used to synchronize the signal in the case of CPICH synchronization.
It is expected at code class 8 and code number 0.
• PSCH
The primary synchronization channel is used to synchronize the signal in the case of SCH
synchronization. It is a non–orthogonal channel. Only the power of this channel is determined.
• SSCH
The secondary synchronization channel is a non–orthogonal channel. Only the power of this
channel is determined.
• PCCPCH
The primary common control physical channel is used to synchronize the signal in the case of SCH
synchronization. It is expected at code class 8 and code number 1.
• SCCPCH
The secondary common control physical channel is a QPSK–modulated channel without any pilot
symbols. In the 3GPP test models, this channel can be found in code class 8 and code number 3.
However, the code class and code number need not to be fixed and can vary. For this reason, the
following rules are used to indicate SCCPCH.
HSDPA/HSUPA On/Off softkey set to Off
– Only one QPSK–modulated channel without pilot symbols is detected and displayed as the
SCCPCH. Any further QPSK–modulated channels without pilot symbols are not detected as
active channels.
– If the signal contains more than one channel without pilot symbols, the channel that is received
in the highest code class and with the lowest code number is displayed as the SCCPCH. It is
expected that only one channel of this type is included in the received signal. According to this
assumption, this channel is probably the SCCPCH.
HSDPA/HSUPA On/Off softkey set to On
– All QPSK–modulated channels without pilot symbols are detected. If one of these channels is
received at code class 8 and code number 3, it is displayed as the SCCPCH. QPSK–modulated
channels without pilot symbols and a code class higher than or equal to 7 are marked with the
channel type CHAN. QPSK–modulated channels without pilot symbols and a code class lower
than 7 are marked with channel type HSPDSCH.
