Analysis of the Transmission Modes and Downlink Control Information in the LTE-Advanced / 5G Network

In release 15 of the LTE-Advanced the list of used DCI formats has been significantly expanded. A further 9 formats were added to the existing 27 formats to support new use cases for existing transmission modes and to plan radio resource allocation supported by the new 5G standard with reduced transmission time intervals. To adequately use the new capabilities in the existing communication system it is necessary to perform a complete analysis of the process of selecting the transmission mode and analyzing the main indicators, on the basis of which the base station evaluates the possibility of using a specific transmission mode for the corresponding conditions in the radio channel.
