NOMA Resource Block As A Commodity Box: Content-Centric QoE-Price Interplay In Wireless Multimedia Communications

Wireless multimedia communications is one of the most rapidly growing technologies of the decade. With explosive growth in network traffic, the service providers struggle to provide satisfactory Quality of Experience (QoE) to the users and increase revenue. Non-Orthogonal Multiple Access (NOMA) has been proposed to cater multiple users simultaneously in each resource block by exponentially increasing the network capacity. However, the strategic allocation and trading of NOMA resource blocks are still open issues. In this work, we treat a NOMA resource block as a commodity representing its channel quality and the importance of data it carries. We then chalkup the innovative and appealing QoE-price interplay to promote NOMA resource block trading as a suitable candidate for future-generation wireless mobile networks. The proposed framework benefits both the utilities of users and service providers. The proposed approach is solved by deriving the Nash Equilibrium of the network interactions using a best-response game. Simulations suggests further exploration of the potentials to the adaptation of proposed framework for NOMA wireless multimedia communications.
