1. A user equipment (UE), comprising:
a transceiver configured to connect to a base station of a network; and
a processor communicatively coupled to the transceiver and configured to perform operations comprising:
monitoring a first physical resource to receive a common downlink control information (DCI) portion of scheduling information for the UE, wherein the first physical resource is a Physical Downlink Control Channel (PDCCH) and wherein the common DCI portion includes a Frequency Domain Resource Assignment (FDRA) field comprising a first bitmap, wherein the first bitmap identifies a resource block (RB) starting index for the UE-specific DCI portion based on at least one of an uplink or downlink bandwidth or a bandwidth allocated for the UE, and further wherein the common DCI portion varies a UE-specific DCI portion payload size based on a number of scheduled UEs;
decoding the common DCI portion to determine information for a UE-specific DCI portion that is transmitted by the base station on a second physical resource, wherein the second physical resource is a Physical Downlink Shared Channel (PDSCH);
monitoring the second physical resource for the UE-specific DCI portion based on at least the information from the common DCI; and
decoding the UE-specific DCI portion based on at least the information from the common DCI.
