We consider downlink multi-input single-output transmission in multi-cell mobile wireless networks. We consider a finite-scatterer directional channel model with imperfect channel state information at the transmitter. Specifically, we assume imperfect knowledge of the signal angles of departure of the scattering components, as well as uncertainty about the relative phase-shifts between the signals arriving over these scattering multipath components. For this situation we determine the outage probability of linear beamforming at the transmitters and utilize the results for multi-user scheduling and admission control. The considered channel model relates to Rician fading and to two wave with diffuse power fading for the special cases of a single specular component and two specular components, respectively.
