非正交多址（NOMA）是下一代无线多媒体业务解决方案中很有前途的解决方案之一，可以缓解通信拥塞和降低时延。另一方面，正交多址（OMA）多年来一直用于无线传输内容。OMA提供的优点将使其在未来几年与NOMA共存。本文的核心思想是利用Uber/Lyft拼车理念，设计以“正交性为中心”的无线接入定价模型；了解无线网络中共享的NOMA和独家的OMA接入价格差异。然后，在同时支持NOMA和OMA资源区块的混合网络上研究了所开发的定价模型的有效性。对基站和移动用户的效用定义进行了数学建模，并利用博弈论方法分析了双方利润最大化的相互作用。提出了一种求解纳什均衡的算法。仿真结果显示了本文开发的正交性驱动定价框架的有效性。此外，研究结果表明，非均匀正交中心定价对基站和最终用户都有更好的效用。
Non-Orthogonal Multiple Access (NOMA) is one of the promising solutions for next-generation wireless multimedia services to mitigate traffic congestion and reduce latency. Orthogonal Multiple Access (OMA) on the other hand has been used over the years to transmit content wirelessly. The merits offered by OMA would make it co-exist along with NOMA in the upcoming years. The key idea of this paper is to leverage Uber/Lyft ride-share philosophy to design the wireless access pricing model to be "orthogonality-centric"; being aware of the shared NOMA and exclusive OMA access price differences in wireless networks. The efficacy of the developed pricing model is then studied on a hybrid network which supports both NOMA and OMA resource blocks. The utility definitions for both the base station and the mobile user are mathematically modeled and the profit maximization interplay between the two parties is analyzed using game theoretic methods. An algorithm to derive Nash Equilibrium solution is presented. The simulations showcase the efficacy of the developed orthogonality driven pricing framework developed in this paper. Furthermore, the results indicate that the non-uniform orthogonality-centric pricing yields better utilities for both the base station and the end user.
