Non-Cooperative Game Based Power Allocation for Energy and Spectrum Efficient Downlink NOMA HetNets

چکیده
In this paper, the tradeoff between spectrum efficiency (SE) and energy (EE) is investigated in terms of interference management power allocation for heterogeneous networks (HetNets) with non-orthogonal multiple access (NOMA). The EE SE modeled as a multi-objective problem (MOP) under maximum quality service (QoS) constraints, which non-convex. MOP relaxed into convex single objective (SOP) by adopting weighted sum strategy hypograph transformation. SOP solved two steps. first step, we propose technique based on non-cooperative (NC) game NOMA HetNets. proposed NC game, macro base station (MBS) small BSs (SBSs) compete an equal priority order to optimize their transmit powers towards maximizing EE. second closed-form formula control allocated users taking account both QoS constraint successive cancellation (SIC) condition. From simulations, can, some dedicated settings, considerably improve over conventional techniques.

Backhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets
Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

Non-orthogonal multiple access (NOMA) has attracted much recent attention owing to its capability for improving the system spectral efficiency in wireless communications. Deploying NOMA in heterogeneous network can satisfy users’ explosive data traffic requirements, and NOMA will likely play an important role in the fifth-generation (5G) mobile communication networks. However, NOMA brings new t...
متن کاملOn the Power Allocation Limits for Downlink Multi-user NOMA with QoS
The fundamental power allocation requirements for NOMA systems with minimum quality of service (QoS) requirements are investigated. For any minimum QoS rate R0, the limits on the power allocation coefficients for each user are derived, such that any power allocation coefficient outside of these limits creates an outage with probability equal to 1. The power allocation coefficients that facilita...
