Abstract

Systems and methodologies are described that facilitate wireless network transmitters blanking or reducing power on portions of bandwidth reserved for control information transmission. This mitigates interference from disparate transmitters. Furthermore, the control information portion can be divided into a plurality of OFDM tiles that are reusable by transmitters for transmitting the control information. In this regard, interference between transmitters is additionally mitigated as the transmitters can multiplex the control information over a plurality of tiles increasing the chance that at least a portion of the tiles are not interfered. The control information can be decoded by the receivers from the portion of tiles with a low probability of interference.
