We consider the downlink of a cellular network with cooperative multiple antenna base stations and single antenna user terminals. Based on a limited number of measured interference channels and an interference prediction strategy, we address the implementation of interference temperatures in a large scale system. With interference temperatures, each base station has linear constraints on its transmit covariance matrix. These constraints limit the intercell interference at mobile devices in other cells to a certain level.
