The mean co‐channel interference in a distributed antenna system with virtual cells is studied, where a few surrounding remote antenna ports of each user form a virtual cell and serve the user. By assuming that time‐division‐multiple‐access is adopted among the users with overlapping virtual cells, the positions of active users at each time slot are modelled as a Matérn point process of type II, and an upper bound of the mean interference is derived and verified by simulation. The analysis shows that the monotonicity of mean interference depends on the path‐loss factor α , which highlights the importance of a carefully selection of virtual cell size according to the propagation environment.
