Mean-Field Transmission Power Control in Dense Networks

We consider uplink power control in wireless communication when a large number of users compete over the channel resources. The CDMA protocol, as supporting technology 3G networks accommodating signal from different sources code domain, represents orthogonal multiple access (OMA) techniques. With development 5G networks, non-orthogonal (NOMA) is introduced to improve efficiency allocation. Our goal investigate whether power-domain NOMA protocol can introduce performance improvement interact with each other non-cooperative manner. It compared where fierce competition among jeopardizes usage. In this work, we conduct analysis an aggregative game model, and show existence uniqueness equilibrium strategy. Next, adopt social welfare population metric, which average utility achieved by user population. shown that under corresponding strategies, outperforms higher for communications.
