- This paper focuses on a distributed multiple spectrumpricing scheme to maximize system capacity in next generationmultiaccess systems, where multimode user equipments (MUEs)can connect simultaneously to multiple base stations (BSs) withmultiple radio access technologies (RATs). The multi-price basedscheme provides a distributed decision making for an optimal solutionwhere radio resource allocations are determined by each MUE,unlike most centralized mechanisms where BS controls the wholeradio resource. By the proposed optimal solution, MUEs can decidetheir share of spectrum bands and power allocation accordingto the spectrum price of each RAT, and at the same time the multiaccesssystem can achieve maximized total throughput. Numericalanalysis shows that the proposed scheme achieves the maximalcapacity by distributed resource allocation for the multiaccess system.
