A user equipment (UE) may receive, from a base station on a first subband, a downlink control information (DCI) having a first predetermined DCI format or a second predetermined DCI format, in which the second predetermined DCI format has a length smaller than the first predetermined DCI format. The UE also may determine that the DCI indicates a downlink feedback information (DFI) based on one or more of an indication in the DCI or a first predetermined scrambling code associated with the DCI, when the DCI is received with the second predetermined DCI format.
