Figure 2-3 Logical Structure of an AAU
An AAU performs the following functions:
lReceives downlink baseband data from the BBU and sends uplink baseband data to the
BBU.
lOn the RX channel, it receives RF signals through feeders, down-converts the RF signals
into IF signals, amplifies them, and performs analog to digital conversion (ADC). On the
TX channel, it filters signals, performs digital to analog conversion (DAC), and up-converts
the RF signals to the TX band.
lMultiplexes RX signals and TX signals to enable these signals to share the same antenna
path, and filters RX and TX signals.
lTransmits or receives radio waves and forms beams.
The following table describes functional modules of an AAU.

Function Logical Structure
AU lProvides AU arrays, feed power, phase shift
network, and drive system.
lProvides built-in remote control units (RCUs) that
can control circuits.
lReports information about the AU capability and
RU in-position status.
lProvides the power supplying channel and
communication ports between the RU and the MU.
lProvides ports for AAU mounting kits.
See illustration AU in
Figure 2-3.
MU lProvides a -48 V DC port.
lProvides CPRI ports for CPRI convergence and
distribution.
lProvides protection and filtering.
lProvides OM of the AAU and management of the
RUs.
See illustration MU in
Figure 2-3.
RU lOn the RX channel, down-converts RF signals into
IF signals, amplifies them, and performs ADC.
lOn the TX channel, filters signals, performs DAC,
and up-converts the RF signals to the TX band.
lMultiplexes RX signals and TX signals on the RF
channel.
lProvides active antenna calibration and
compensation and parameter configuration.
lExchanges data between the AU and MU.
See illustration RU in
Figure 2-3.
