Intercell interference is viewed as the main impairment in modern wireless systems, and its mitigation is a top research priority. Chief among the techniques being considered for this purpose are cooperative transmission and/or reception, and it is widely believed that that these strategies hold the potential to turn today?s interference-limited networks into noise-limited ones. This talk addresses this issue from fundamental perspectives, establishing some limits to what cooperation can actually achieve in mobile channels. The validity of the standard notions of ?high SNR? and ?spatial degrees of freedom? are delineated within the context of large wireless networks, with multipath fading re-emerging as a stubborn foe.
