+ The radio part is located in the RUS unit

+Multi Carrier Power Amplifier (MCPA) will be capable of amplifying signals from many TXs at the same

time.

1.' MCPA Power Overbooking and Temporary Power Override

3Overbooking ( one TS)

+ The sum of BSC configured TX power for all TRXs using the same MCPA may exceed the maximu

MCPA Power

Normally not all users that want to transmit via the MCPA at a certain time need the full configu

power.

Some channels might not be allocated at all, other users may be configured these power.

+This is allowed only if:

Feature GSM MCPA Intelligent Power Management is available

Configuring HW activation codes for at least 3 GSM TRXs

Configuring HW activation codes for MCPA power corresponding to the maximum MCPA power

3Temporary power override (one MCPA)

+When the MCPA power isoverbooked

there is though a theoretical risk that the MCPA power is not enough to cover the need for all usersthat want to transmit via the MCPA at a certain time

+Temporary power overridemakes it possible to overuse the MCPA power for short periods of tim

as long as the long time average is kept below the maximum MCPA power

The temporary power override functionality is not available for all RUS configurations (For insta

configuring a RUS 02 for 6 TRXs or more)

1.+ MCPA !ac%ed,o&&

+ If the sum of ordered power on all TRXs exceeds the MCPA maximum power during a specified time the channe

used for the most robust connections (the lowest priority channels) will be backed-off

+ If the maximum allowed amount of back-off for the channels with lowest priorityis not enough to reach the goal,

then also channels with the second lowest priority will be backed-off and so on.

+ If temporary power override is activated the mean power averaged during a longer time (several TDMA frames)

monitored. If not, the mean power for each TS is monitored
