Some embodiments may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some embodiments may utilize an enhanced physical downlink control channel (ePDCCH) that uses PDSCH resources for control information transmission. The ePDCCH may be transmitted using one or more enhanced control channel elements (ECCEs). Similar to the above, each ECCE may correspond to nine sets of four physical resource elements known as enhanced resource element groups (EREGs). An ECCE may have other numbers of EREGs in some situations.
