System and method embodiments are provided for a subframe structure for wideband LTE. In an embodiment, a method in a communications controller for transmitting a packet to a wireless device includes signaling a UL/DL configuration to the wireless device, wherein the UL/DL configuration indicates a quantity of uplink microframes in a group of microframes, wherein each subframe includes a plurality of microframes, and wherein the group of microframes includes a consecutive sequence downlink microframes and a consecutive sequence of uplink microframes. The packet is transmitted to the wireless device in one downlink microframe. The method further includes receiving an acknowledgement of the packet in an uplink microframe, wherein the uplink microframe is determined in accordance with the one downlink microframe and the uplink-downlink configuration, and wherein the acknowledgement is received in a same subframe as a subframe utilized for transmitting the packet to the wireless device.
