Abstract Distributed virtual group cell systems become a possible solution for future wireless communication systems, which has flexible structure and huge potential in terms of increasing spectrum efficiency and improving quality of communications. In this paper, a Markov model is adopted to analyze the performance of multi-antenna based virtual group cell systems. Numerical results, such as blocking probability, handoff failure probability etc., are given with interference-based admission control algorithm. The investigation shows that the uplink performance of this system can be improved greatly.
