Admission control in MIMO-based virtual group cell systems

The multiple input multiple output (MIMO) system is a huge reform to future wireless communication systems. The proposed MIMO-based virtual group cell structure is a novel cellular construction method, which is suitable for new advanced physical techniques. However, existing radio resource management algorithms are not suitable for multiple antenna environments. The paper improves the traditional admission control algorithm and makes it suitable for MIMO systems. According to the characteristics of the new network architecture, a different interference distribution model is provided to help evaluate the system performance.
