Abstract: An SHF or an EHF band has a problem for providing a communication link in a shadow area according to strong linear features. The present invention provides a communication link to the shadow area of the SHF or the EHF band which is difficult to obtain a line of sight (LOS) communication signal (110). Therefore, the present invention provides a method for enabling a terminal to use a multiple input multiple output (MIMO) technology by artificially generating in a communication environment.

Abstract: PURPOSE: A communication method using a multi-radio interface is provided to increase data transmission performance by interoperating a plurality of wireless interfaces. CONSTITUTION: A wireless terminal configures TCP connection with a reception device through a second wireless communication network(310).
