A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback. Where overhead is not the only problem, usage of two symbols is proposed due to the limitations of radio frequency beamforming.

The method of claim 28, wherein an allocation unit comprises a predetermined amount of OFDMA symbols in time and subcarriers in frequency.
The method of claim 28, wherein an allocation unit has a different size in the first part and the second part.
The method of claim 28, wherein the downlink control information comprises information about the allocation for the data transmission in the first part and/or the second part.
The method of claim 28, wherein the configuring information is semi-static and is provided via higher layer control signaling.
The method of claim 28, wherein a data allocation into the first part is based on an indication of allocation units not used for the control information.
The method of claim 28, wherein a separate DCI format supports the data transmission in the first part.
The method of claim 28, wherein a beam switching gap is included between consecutive OFDMA symbol carrying the downlink control information.
The method of claim 28, wherein the data transmission with a higher latency requirement over a threshold is configured in the first part.
