Signalling of Frequency-Domain Resource Assignment

Abstract:

Embodiments include methods in a communication system including host computer, base station, and UE. The base station can send the UE an indication of an active bandwidth part (BWP) of a size NZ.sub.BW P,1.sup.size frequency-domain resource blocks (RBs), and select frequency-domain RBs, within the active BWP, to be assigned for carrying the user data to the UE. The base station can encode an indication of the selected frequency-domain RB(s) represented by a starting virtual RB, RB.sub.start, and a length of contiguously allocated RBs, L.sub.RBs, using a number of bits. The number is a plurality and related to a size N.sub.BW P,2.sup.size of another BWP than the active BWP. N.sub.BW P,2.sup.size is smaller than N.sub.BW P,1.sup.size. The starting virtual RB is encoded with a resolution of K RBs, with K determined based on a ratio of N.sub.BW P,1.sup.size and N.sub.BW P,2.sup.size. The base station can send the encoded indication to the UE via a downlink control channel.
