A method for allocating communication resources in a wireless network by collecting data related to network conditions and terminal device requirements; selecting predetermined resource block allocations for terminal devices and wherein a sub-carrier spacing is selected based on a numerology for the bandwidth part (BWP) which influences RBG configuration and allocation of RBs to terminal devices; encoding the resource block allocations into a resource indication information with a most significant bit (MSB) indicating whether a resource block set belongs to the frequency domain resources of the data channel; and transmitting the resource indication information to the terminal devices.
