Abstract： 5G communication technology has the characteristics of large bandwidth， high reliability and low delay， and supports the business integration with vertical industries. It has become an effective way to solve the rail transit communication business. This paper analyzes the application and verification of 5G technology in Maqun test line of Nanjing Metro and ningju intercity line， and puts forward the thinking of 5G technology carrying signal train ground business， which provides a reference for the further research of 5G technology in the field of urban rail transit.

Key words： 5G communication technology; urban rail transit; signalling system; train ground wireless communication; moving edge calculation
