Group cell

generalized distributed cellular architecture for china beyond 3G mobile communication systems

was proposed to increase coverage area

adopt new techniques and solve the frequent handover problem with increase of carrier frequency.In order to analyze the optimal size selection for group cell

namely the number of cell antennas in a cell group

the power cost model is firstly set up to give the criterion of selection.Then average received power and average received signal to interference ratio are respectively taken as the criteria

including outage probability.Finally

the optimal size selection for group cell is given due to the three pieces of criteria.Based on the simulation and analysis

the optimal size selection criteria are applicable to certain generalized distributed cellular architecture with different performance demands.
