Spectral Efficiency of Dynamic Coordinated Beamforming: A Stochastic Geometry Approach

Base station (BS) coordination is regarded as an effective approach to mitigate intercell interference. The idea is to allow multiple BSs to coordinate their transmit and receive strategies (e.g., beamforming, power control, and scheduling) by utilizing channel state information (CSI). A central concept in the implementation of BS coordination with low overheads is to form a cluster, defined as the set of BSs that a given user coordinates with. From the vantage of a user, only those BSs outside the cluster are sources of interference.
