Abstract

The present disclosure relates to 5G or pre-5G communication systems capable of achieving much higher data rates than 4G communication systems like LTE systems. A method for a base station to provide different services may include determining overlap related information for a first terminal of a first system employing a first transmission time interval (TTI) and a second terminal of a second system employing a second TTI different from the first TTI. The method may also include transmitting scheduling information containing the overlap related information to the first terminal and the second terminal and transmitting data to the first terminal and the second terminal based on the overlap related information.
