Abstract: A method and terminal device for executing a radio application is disclosed. The method for executing a radio application is a method for executing a radio application independent of a modem in a terminal device, comprising the steps of: communicating with each other using a reconfigurable radio frequency interface (RRFI) by a unified radio application (URA), which operates on a radio computer of the terminal device, and a radio frequency (RF) transceiver, which operates in a radio platform on the radio computer; and supporting, by the RRFI, at least one service among a spectrum control service, a power control service, an antenna management service, a transmission/reception chain control service, and a radio virtual machine protection service.

Abstract: Disclosed is a method for distributing, installing, and operating a software-defined radio-based radio application independent of hardware and a user application. A radio application distribution method for installing a radio application in a user terminal using a radio application package comprises the steps of: generating a radio application package including a radio controller code, compiled by an application processor compiler, and a user-defined function block; and uploading the radio application package to a server, wherein the radio controller code is in the form of an execution code executed by an application processor or radio computer of the user terminal, and provides a user application of the user terminal with context information of a radio application to be installed in the user terminal or defines a radio controller for transmitting and receiving data with a networking stack of a communication service layer located in the application processor.
