The nominal power level is used if BS Power is not received at channel
activation. The "BS Power" received is stored in the RBS to be used
for the requested dedicated channel.
The RBS is able to reduce its BS power level (starting from the
nominal power level) in up to 15 steps of 2 dB (nominal value), as
defined by the BSC.
If the RBS receives a BS Power which would result in a setting below
the lowest level allowed, the BS power level is tuned into the lowest
level allowed. The maximum BS power level used for a specific
channel never exceeds the nominal BS power level.
The commanded BS Power level is applied on each transmitted burst,
except for bursts on a BCCH carrier, where the nominal BS Power level
is used on all timeslots. An attempt to change the BS Power level for a
channel on a BCCH carrier, is accepted but has no effect.
22.3.2 Base Station Power Control for an Active Channel
By means of the TRANSMISSION POWER CONTROL procedure /
GSM:08.58:4.9/ the BSC defines the TRX transmission power level.
The RBS support:
• Interpretation of BS_POWER_CONTROL message from BSC
• Storage of BS Power
• Adjustment of BS power level
Supported channel numbers, channel combinations and handling of the
received BS power level are as described in chapter Base Station Power
Control, see table of contents.
The BS power change starts at the first TDMA frame belonging to a
SACCH reporting period. When the RBS has received a new BS power
level, the BS power is changed within two SACCH reporting periods
22.3.3 Base Station Power Control at Channel Reactivation
SeeSection 22.3.1 on page 217.
22.4 Operational Conditions
The power level setting follows /GSM:05.05:4.1.2/, according to power
level step size, maximum output power and tolerances.
