In 3GPP TS 36.213, section 5.1.1.1 this parameter is called P
O_NOMINAL_PUSCH
.
Remote command:
Pathloss Compensation Alpha
Specifies the parameter "alpha", signaled to the UE as uplink power control parameter
(see 3GPP TS 36.331, section 6.3.2).
In 3GPP TS 36.213, section 5.1.1.1 this parameter is called
α
.
Remote command:
Toggle P0-UE-PUSCH at RRC Setup
With enabled toggling, the following P0-UE-PUSCH values are set during RRC con-
nection setup:
●
RRC Connection Setup message (SRB1): P0-UE-PUSCH = 1 dB
●
RRC Connection Reconfiguration message (SRB2+DRB): P0-UE-PUSCH = 0 dB
P0-UE-PUSCH toggling is required for some 3GPP conformance tests, for example
3GPP TS 36.521, section 6.3.5.1 "Power Control Absolute power tolerance", table
6.3.5.1.4.3-4.
The toggling initiates a "TPC accumulation reset" at the UE (f
c
(i) is set to 0, see 3GPP
TS 36.213, section 5.1.1.1).
Note:
Toggling deletes a PRACH ramp-up procedure. Disable toggling if a PRACH
ramp-up procedure is required for decoding of the UE signal. Otherwise the RRC con-
nection setup will fail.
Note:
Use toggling only if the external attenuation is compensated accurately. Do not
use toggling if this cannot be ensured, for example for over the air tests with fluctuating
external attenuation.
Remote command:
Pathloss
Displays the pathloss resulting from the
Remote command:
Expected PRACH Preamble Power
Displays the expected power of the first preamble.
The value depends on the "preambleInitialReceivedTargetPower" (
on page 139) and on the preamble format resulting from the
