Abstract	Multihop communication has attracted a lot of attention as an effective transmission strategy for future cellular networks. It can be an effective technique to increase data rate and enhance coverage. However, multihop relaying with a single Radio Access Technology (RAT) may not be able to provide the flexibility required for wireless cellular network which has moved towards heterogeneity. Therefore, multihop cellular network needs to be integrated with multi-RAT to provide the required flexibility in the cellular architecture. When multihop cellular network is provided with multi-RAT capability, RAT selection for a certain transmission session becomes part of its resource management. RAT selection decision depends on the characteristics of the radio links and the availability of resources in the different RATs. A careful control of power between user and relay is required to exploit multi-RAT and multihop capabilities to their maximum potential. In this paper, we formulated a RAT selection and a transmission power control for a mobile user and relay using an indifference curve. We selected the RAT and allocated the power for a single users transmission such that the interference created by the mobile user and the relay is minimized and the achievable data rate is satisfied.
