Abstract: A network node in a new radio access technology (RAT) configures a fixed resource on which transmission direction is fixed and a flexible resource on which transmission direction is changeable, and transmits a single channel which is mapped to the fixed resource and the flexible resource. The single channel may be divided into a first mini channel which is mapped to the fixed resource and a second mini channel which is mapped to the flexible resource.
