Abstract
Disclosed herein are systems and methods for choosing the size of the control region of a downlink subframe. For example, an apparatus for selecting the size of the control region based on a set of one or more physical downlink control channels (PDCCHs) is disclosed. The apparatus, in some embodiments, includes: a module configured to determine, for each of at least two or more control region sizes included in a set of two or more control region sizes, a subset of PDCCHs from said set of PDCCHs that can be assigned to a control region having a size equal to the control region size; and control region size selector for selecting a control region size for the subframe, wherein the control region size selector is configured to make the selection based, at least in part, on information pertaining to the subset of PDCCHs that can be assigned to a control region having a size equal to the selected control region size.
