Resumo: |
The popularization of mobile communications leads to the continuous increase of Quality of Service (QoS) demands. Modern networks offer many service types that need to be considered to a fair distribution of the available radio resources. One of the main strategies of the next generation of mobile communications in order to deal with that traffic increase is the densification of Acess Points (PA). This approach consists in reducing the distances between transmitters and receivers in order to maximize the available channels per area. However, the PA densification also comes with a drawback: the increase in the interference that should be appropriately managed. This work proposes an optimal solution to the Physical Resource Block (RB) distribution in order to maximize the sum rate in a multicell and multiservice system constrained to a percentage of users that should be satisfied per service. The nature of this kind of problem usually gives priority for terminals in better channel qualities that leads to an unfair solution to terminals in the edge of hexagonal cells. The proposed formulation allows that the same criteria of quality can be applied in the edge of cell. A variation of this problem considering stochastic geometry is also proposed with small performace loss. |
