Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.
