Functions

The LRFU processes uplink and downlink services and controls and monitors internal boards
or modules.

Figure 4-41

shows the logical structure of the LRFU.

Figure 4-41

Logical structure of the LRFU

The uplink RX channels implement the following functions:

l

Filters and amplifies two uplink signals and performs digital down-conversion, analog-to-
digital (A/D) conversion, digital Inphase Quadrature (IQ) signal demodulation, and
matched filtering.

l

Performs uplink Automatic Gain Control (AGC) and stabilizes the level in the IQ digital
domain of the BBU-RFU interface.

l

Frames the IQ signals of the BBU-RFU interface.

l

Reports the Received Signal Strength Indicator (RSSI).

The downlink TX channels implement the following functions:

l

Deframes the IQ signals of the BBU-RFU interface.

l

Shapes and filters downlink IQ signals, performs digital up-conversion, digital-to-analog
(D/A) conversion, and amplifies the power.

l

Reports the transmit power.

l

Provides overload protection of the power amplifier.

l

Enables or disables TX channels.

l

Provides closed-loop power control.

l

Simulates the downlink load.

The control module implements the following functions:

l

Provides the interface for reporting backup power alarms.

l

Provides the functions of the Remote Electrical antenna Tilt (RET) antenna.
