TD-HSPA mode (active cell)
Call connection types
RB test mode:
–– BS origination and release
–– HSPA RB test mode is operated on the downlink, simultaneously supporting as symmetrical
RMC of 12.2 kbps
TD-HSPA RF generator
Downlink channel power level: All downlink timeslot power levels are fixed to the cell
power. The physical channels in one timeslot have separate relative powers and the
relative power of the channels in one timeslot must sum to 100% of the timeslot power
HS-SCCH relative level: –6.02 dB if only one HS-SCCH channel is configured; –6.97
dB if four HS-SCCH channels are configured; –6.02 dB, –7.78 dB,
–8.45 dB, and –6.02 dB for FRC1a, FRC1b, FRC2, and FRC3 respectively if TD-HSUPA
is configured
HS-DSCH relative level: 0 dB, –0.79 dB, –1.46 dB for FRC1b, FRC2 respectively if
TD-HSUPA is configured
E-PUCH relative level: 0 dB
E-AGCH relative level: –6.02 dB, –3.01 dB, –8.45 dB, and –6.02 dB for FRC1a, FRC1b,
FRC2, and FRC3 respectively
E-HICH0 relative level: –9.03 dB, –6.02dB, –11.46 dB and –9.03 dB for FRC1a,
FRC1b, FRC2 and FRC3 respectively
E-HICH1 relative level: –9.03 dB, –6.02dB, –11.46 dB and –9.03 dB for FRC1a,
FRC1b, FRC2 and FRC3 respectively
Downlink CDMA modulation
Modulation type: QPSK and 16QAM per 3GPP standard
QPSK residual EVM: < 10%, typically < 3%
QPSK carrier feed through: < –25 dBc, typically < –35 dBc
TD-HSPA RF analyzer
Real-time demodulation of: DPCH, HS-SICH and E-DCH
Downlink CDMA modulation
Modulation type: QPSK per 3GPP standard
QPSK residual EVM: < 10%, typically < 3%
QPSK carrier feed through: < –25 dBc, typically < –35 dBc
