Table 3-3: Limits for BPSK modulated channels (no 4PAM channels present)
ECDP
RCDE Limit
ECDP > -21 dB
≤ -15.5 dB
-21 dB ≥ ECDP ≥ -30 dB
≤ -36.5 dB - ECDP
These limits are configured as default values in the configuration dialog.
4PAM Modulated Channels Configured
This section applies if the uplink signal contains at least one 4PAM modulated channel.
BPSK modulated channels may also be configured. The requirements are described in
the following 3GPP TS 34.121 section:
●
5.13.2C Relative Code Domain Error for HS-DPCCH and E-DCH with 16QAM
According to 3GPP limit checks are required if the following conditions are met for all
channels:
●
nominal CDP ≥ -30 dB
●
ECDP ≥ -30 dB
These conditions are not checked automatically. Please enable/disable the limit checks
of the individual channels manually, according to the displayed nominal CDP and
ECDP values.
The applicable limits differ for BPSK and 4PAM modulated channels and are listed in
the following tables.
Table 3-4: Limits for BPSK modulated channels (4PAM channels present)
ECDP
RCDE Limit
ECDP > -22 dB
≤ -17.5 dB
-22 dB ≥ ECDP ≥ -30 dB
≤ -39.5 dB - ECDP
Table 3-5: Limits for 4PAM modulated channels
ECDP
RCDE Limit
ECDP > -25.5 dB
≤ -17.5 dB
-25.5 dB ≥ ECDP ≥ -30 dB
≤ -43 dB - ECDP
The 4PAM limits are configured as default values in the configuration dialog. The
BPSK limits have to be adjusted if 4PAM channels are present.
3.2.5.3
Power Control Limits
The transmission of ACK/NACK or CQI over the HS-DPCCH causes UE power steps.
The allowed limits for these power steps are defined in 3GPP TS 34.121, section 5.7A
"HS-DPCCH power control". Two test cases are distinguished in the specification:
●
Measurement at maximum UE power with TPC command = 1 ("TPC 1dB")
●
Measurement below maximum UE power with TPC command = 0 ("TPC 0dB")
