A RRA collects information on radio resources and supervises the ... users share radio resources. This sharing can be enabled through a simple mechanism where cell-edge users use radio resources first and the cell-interior users use the residual radio resources. This ... of PF scheduling. 8. Conclusion We have proposed a new RRM framework for wide- area wireless data networks that manages radio resources of cell-interior and cell-edge users separately. We believe that...
