Abstract :
Recent simulation studies of heterogeneous wireless networks have shown promising system performance improvements by using multi standard radio resource management (MxRRM) with a centralised MxRRM architecture. In the present paper, the distributed MxRRM architecture is studied, including the modelling of signalling, where intersystem cell load information can only be exchanged at certain events. Consequently, the distributed MxRRM entities have to base their decisions on potentially inaccurate load information. The system performance is investigated by simulation studies, where the results of distributed MxRRM scenarios are compared to two reference cases, 1) assuming ideal system information for MxRRM and 2) separated systems without any MxRRM functionality. Furthermore, an additional dedicated mechanism to exchange the load information aiming to improve the load information accuracy is investigated
