Abstract: A frame structure for a new radio access technology (RAT) is configured by a network node. The network node configures a first frame which has one legacy transmission time interval (TTI) and a second frame which has multiple short TTIs, and communicates with a user equipment (UE) by using at least one of the first frame and the second frame. The UE may be a one of a massive machine-type communication (mMTC) UE, an ultra-reliable and low latency communication (URLLC) UE or an enhanced vehicle-to-everything (eV2X)
