Abstract
This paper proposes a joint radio resource allocation algorithm for uplink parallel multi-radio access (MRA)in heterogeneous networks, first introducing an economic link utility function, which quantifies Quality of Experience (QoE) satisfaction level of user, as a combination of link reward and resource cost function. Then, a QoE-based joint resource allocation algorithm is proposed for the efficient sharing of radio resources by multi-mode terminals, so that uplink system utility is maximized. In particular, this work studies two cases of parallel MRA systems that are distinguished by the existence of free wireless access points. We provide a sensitivity analysis on how cost in the joint resource allocation algorithm affects the performances of various parallel MRA systems.
