Abstract
A dynamic and distributed multiuser radio resource allocation scheme for a FDMA-TDMA based multicellular system is proposed. User interference measurements and channel estimation at the mobiles are used in order to exploit the multiuser diversity of the system. Basic information bearers (i.e. the subcarrier/time-slot pairs) are efficiently allocated and power loaded to accommodate the users rate-demands and dynamically adapt to the interference produced by neighboring cells. Our solution leverages on the possibility to feed the RRM algorithm with parameters coming from different layers, following a cross-layer approach.
