Transmission of user equipment (UE) specific control information within a resource allocation including resource blocks allocated for downlink transmissions to the UE is disclosed. Common control information may be provided in a first transmission time interval (TTI)-level control region, and UE-specific control information, specific to a particular UE, may be provided along with data in allocated downlink resources to the UE. A base station may identify a resource block (RB) for transmission of data to a UE along with UE-specific control information to be included in the RB. The control information may include, for example, parameters for use by the receiver in demodulating the RB. The base station may multiplex the control information with the data within the RB and transmit the RB and control information.
