Abstract
A method for managing radio resources in a multiple radio access technology (multi-RAT) wireless communication network, which includes one or more orthogonal frequency-division multiple access (OFDMA)-based base stations that implement different radio access technologies (RATs), includes the step of creating, for each of a plurality of mobile terminals, an incoming queue where data destined to the respective mobile terminal is buffered. Queue information of each mobile terminal is collected and provided to the multi-RAT wireless communication network. System constraints of the multi-RAT wireless communication network are defined and network constraint information is provided. Based on the queue information and the network constraint information, a resource scheduling algorithm is executed that jointly determines: an allocation of physical resource blocks (PRBs) to each link between a RAT and a mobile terminal, an assignment of modulation levels to each of the allocated PRBs, and an activation/deactivation of each of the RATs.
