Parameters for each base station (BS)

State

OFF/ON

2nd search code group

0 to 63 (depending on scrambling code)

Scrambling code

0 to 5FFFF hex or off

TFCI state

OFF/ON

TFCI

0 to 1023

TPC pattern readout mode

use of TPC pattern:
continuous, single + all 0, single + all 1, single + alternating 01,
single + alternating 10

Use TPC for dynamic output power control

OFF/ON
if this function is active, the TPC pattern is used to vary the transmit
power of the code channels versus time

Output power control step

–10 dB to +10 dB

Transmit diversity

OFF/antenna 1/antenna 2
if this function is active, the output signal for antenna 1 or
antenna 2 can be generated as defined in the standard

Parameter for each mobile station (MS)

State

OFF/ON

Mode

PRACH only, PCPCH only, DPCCH + DPDCHs

Scrambling code

Scrambling code mode

long, short, off

TPC pattern

all 0, all 1 and bit pattern (max. 24 bit long)

TPC pattern readout mode

use of TPC pattern:
