SYSTEMS AND METHODS FOR DOWNLINK CONTROL INFORMATION (DCI) SIZE ALIGNMENT

Abstract:

Embodiments of a method of operation of a wireless device for providing Downlink Control Information (DCI) format size alignment between a first DCI format a second DCI format and corresponding embodiments of a wireless device are disclosed herein. In some embodiments, the method of operation of the wireless device comprises determining one or more Resource Block Group (RBG) parameters for interpreting a frequency-domain resource allocation for the first DCI format. The RBG parameter(s) are either a RBG scaling factor(s) or a RBG size(s). The RBG parameter(s) adjust a granularity of the frequency-domain resource allocation for the first DCI format such that a size of the first DCI format is aligned with a size of the second DCI format. The method further comprises receiving DCI having the first DCI format and interpreting the frequency-domain resource allocation of the DCI in accordance with the one or more RBG parameters.
