Systems and methods for a subframe structure for wideband LTE

A communications controller comprising:

• a non-transitory memory storage comprising instructions;
• and
• a processor in communication with the non-transitory memory storage, wherein the processor executes the instructions to :
• signal a higher layer signal indicating a plurality of downlink frames and a plurality of uplink frames;
• signal a first downlink control information (DCI) message that includes a first indicator for a portion of a downlink frame, in the plurality of downlink frames, for transmitting a packet to a wireless device and a second indicator for a portion of an uplink frame, in the plurality of uplink frames, for receiving an acknowledgement associated with the packet from the wireless device;
• and
• receive the acknowledgement in the portion of the uplink frame.
