Abstract
We consider cooperative opportunistic
beamforming that can mitigate the other cell
interference (OCI) in correlated multi-user
multiple-input single-output (MISO) cellular
environments. By only exploiting the spatial channel
information of adjacent cells, the proposed scheme
generates the cooperative random beam that
statistically avoids the OCI from adjacent cells. Each
cell selects a user in an opportunistic manner. Thus,
the proposed scheme can simultaneously achieve the
multi-user diversity (MUD) gain and the OCI
avoidance gain.
