Parameter Value Restrictions and Couplings by Channel Type
This section contains information on parameter value restrictions, changes requiring data
precomputation and regeneration, and parameter couplings.
CPICH
DPCH
General restriction: in order for the ESG to precompute data for baseband generation, you
must press the
Apply Channel Setup after any one of following actions:
Changing any DPCH parameter value (except for power)
Changing from any other channel type to DPCH
Changing from DPCH to any other channel type
Parameter Restrictions Notes
Power None
Channel Code
Not
user-selectable.
0 only, by 3GPP specification.
Parameter Restrictions Notes
Power None No Apply Channel Setup key press necessary.
Channel Code
None
Coupled to Slot Format, Spread Factor, and Symbol Rate. For
valid values, see
Table 4-8.
SecScr Code
OS
None
Coupled to BS primary scramble code.
TPC Pat Steps
Must be same for
all DPCH.
Entering a value in one DPCH will enter the same value in all
other DPCHs.
Data
Must be same for
all DPCH.
Entering a value in one DPCH will enter the same value in all
other DPCHs.
Symbol Rate Not user selectable. Assigned based on Slot Format. Also coupled to Channel Code
and Spread Factor. For valid values, see
Table 4-8.
TFCI Pattern
Must be same for
all DPCH.
Entering a value in one DPCH will enter the same value in all
other DPCHs.
TPC Pattern
Must be same for
all DPCH.
Entering a value in one DPCH will enter the same value in all
other DPCHs.
Slot Format
Must be same for
all DPCH.
Coupled to Channel Code, Symbol Rate and Spread Factor. For
valid values, see
Table 4-8.
Time Offset
Must be same for
all DPCH.
Entering a value in one DPCH will enter the same value in all
other DPCHs.
