RANDOM REUSE BASED CONTROL CHANNELS

摘要

PROBLEM TO BE SOLVED: To receive control information while mitigating interference from other transmitters.SOLUTION: The interference is mitigated by wireless network transmitters blanking or reducing power on a portion of bandwidth reserved for control information transmission. The control information portion is divided into a plurality of OFDM tiles that are reusable by the transmitters for transmitting the control information. The transmitters multiplex the control information over the plurality of tiles to increase the probability that at least a portion of the tiles are not interfered, thereby further mitigating the interference between the transmitters. Receivers decode the control information from the portion of tiles with a low probability of the interference.
