Abstract

Embodiments include methods for receiving, by a user equipment (UE) in a wireless network, assignment of frequency-domain resources of a communication channel. Such embodiments include receiving an indication of an active carrier bandwidth part (BWP) of a size NBWP,1size frequency-domain resource blocks (RBs). Such embodiments include receiving, via a downlink control channel, an indication of assigned frequency-domain RB(s) within the active BWP, with the indication being encoded with a plurality of bits related to a size NBWP,2size of a BWP than the active BWP, where NBWP,2size<NBWP,1size. Such embodiments include decoding the indication to obtain the assigned RB(s) represented by a starting virtual RB and a length of contiguously allocated RBs. The starting virtual RB is encoded with a resolution of K RBs, with K based on a ratio of NBWP,1size and NBWP,2size. Embodiments also include complementary methods performed by network nodes, and apparatus configured to perform these methods.
