To improve link reliability and data throughput in wireless communications, it is well known that we can exploit both the spatial and the temporal domain by precoding and scheduling, respectively. For cellular networks, however, most of these gains can only be obtained when frequency resources are carefully allocated to the different base stations as otherwise, they are compromised by the presence of intercell interference. To achieve universal frequency reuse among base stations, the idea of base station cooperation has recently attracted much attention. Unfortunately, the costs of this cooperation in terms of channel state information diminish most of the benefits. This paper proposes scheduling and precoding techniques under universal frequency reuse that address these costs to recover the gains of temporal scheduling and spatial precoding in the downlink of cellular multiple input single output (MISO) systems with multiple non-cooperative users per cell.
