New Optimal and Suboptimal Resource Allocation Techniques for Downlink Non-orthogonal Multiple Access
This paper investigates several new strategies for the allocation of radio resources (bandwidth and transmission power) using a non-orthogonal multiple access (NOMA) scheme with successive interference cancellation (SIC) in a cellular downlink system. In non-orthogonal access with SIC, the same subband is allocated to multiple users, which requires elaborate multiuser scheduling and subband ass...
متن کاملOn Non-Orthogonal Multiple Access in Downlink
Non orthogonal multiple access (NOMA) in the downlink is discussed in this letter. When combined with soft frequency reuse, NOMA is detrimental to user fairness by increasing the data rate of a near user at the cost of data rate of a far user.
متن کاملA Fair Power Allocation for Non-Orthogonal Multiple Access in the Power Domain
This paper presents an investigation on the performance of the Non-Orthogonal Multiple Access (NOMA) in the power domain scheme. A Power Allocation (PA) method is proposed from NOMA throughput expression analysis. This method aims to provide fair opportunities for users to improve their performance. Thus, NOMA users can achieve rates higher than, or equal to, the rates obtained with the convent...
متن کاملFrom Orthogonal to Non-orthogonal Multiple Access : Energy- and Spectrum-Efficient Resource Allocation
The rapid pace of innovations in information and communication technology (ICT) industry over the past decade has greatly improved people’s mobile communication experience. This, in turn, has escalated exponential growth in the number of connected mobile devices and data traffic volume in wireless networks. Researchers and network service providers have faced many challenges in providing seamle...
متن کاملDownlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks
A network model is considered where Poisson distributed base stations transmit to N power-domain non-orthogonal multiple access (NOMA) users (UEs) each that employ successive interference cancellation (SIC) for decoding. We propose three models for the clustering of NOMA UEs and consider two different ordering techniques for the NOMA UEs: mean signal power-based and instantaneous signalto-inter...
