  The modern mobile communication systems, the task of analyzing the parameters
of quality of service and network information load remains one of the most
popular. There are several ways getting this information in LTE networks. For
example, by evaluation of test signals or estimation special reference signals
in LTE frame. In this paper, it is proposed to obtain information about the
cell load by decoding service messages of the DCI control information block.
The main idea of this method is that the information load of LTE cell is
estimated by decoding DCI messages in the LTE physical control channel and
establishing the number of unique identifiers. For decoding the LTE signal, was
used MATLAB LTE Toolbox and software-defined radio platform USRP 2920. In the
work, the UE detection algorithm was tested on the signal generated using
MATLAB software, and evaluated the information load of the network of a real
LTE base station.
