Abstract:

With the widespread deployment and use of MTC（machine-type communication）devices,MTC has been closely integrated with the mobile communication network.Significant increase in the number of MTC devices causes more strict requirements for communication system.According to the characteristics of MTC communication and the development trend,three key areas of MTC in current LTE-Advanced network were discussed:RAN overload contro1,efficient radio resource allocation and energy savings.Several research challenges that need to be addressed for scalable support of MTC devices for R12 and beyond were summarized,typical optimization methods and solutions were introduced,and corresponding improvement directions according to the current application status were put forward.

Key words: machine-type communication, LTE-Advanced, air interface, overload contro1, resource allocation, energy saving
