Abstract
The herein disclosed apparatus, systems, and methods use Almost Blank Subframes (ABS) to manage interference between D2D and WAN transmissions. In particular, an eNodeB is disclosed comprising a controller module operable to obtain an indicator of a need for a quiescent subframe, and to select responsively thereto a subframe of a communication frame, and allocate the selected subframe as an Almost Blank Subframe (ABS). The base station includes a transceiver module operable to communicate the ABS over an air interface, and to send a misinformation signal to another eNodeB device indicating the ABS is not almost blank.
