1.3.2 Logical Structure of the RRU3606

This describes the logical structure of the RRU3606, which is used for up-conversion and

down-conversion of signals and for power amplification.

The RRU3606 performs the following functions:

This section describes the software structure of the BTS. The BTS software consists of the

platform software, signaling protocol software, operation and maintenance software, and data

center.

The signaling protocol software, operation and maintenance software, and data center are

applications, whereas the platform software is supporting software.

shows the logical structure of the RRU3606.

On the forward link, implementing up-conversion and power amplification for

modulated transmitted signals and filtering the transmitted signals to make them meet the

requirements of the air interface protocol

On the reverse link, filtering the signals received by the antenna to suppress out-band

interference and then performing low noise amplification, down-conversion, and

channel-selective filtering.
