Downlink 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...
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 کاملNon-Orthogonal Multiple Access (NOMA) in Cellular Uplink and Downlink: Challenges and Enabling Techniques
By combining the concepts of superposition coding at the transmitter(s) and successive interference cancellation (SIC) at the receiver(s), non-orthogonal multiple access (NOMA) has recently emerged as a promising multiple access technique for 5G wireless technology. In this article, we first discuss the fundamentals of uplink and downlink NOMA transmissions and outline their key distinctions (i...
متن کاملNon-Orthogonal Multiple Access (NOMA) for Future Radio Access
This paper presents a non-orthogonal multiple access (NOMA) concept for future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), NOMA superposes multiple users in the power domain although its basic signal waveform could be based on the orthogonal frequency division multiple access (OFDMA) or the discrete Fourier tra...
متن کاملResource Optimization and Power Allocation in Full Duplex Non-Orthogonal Multiple Access (FD-NOMA) Networks
In this paper, we study the problem of uplink (UL) and downlink (DL) resource optimization, mode selection and power allocation in wireless cellular networks under the assumption of full duplex (FD) operation, non-orthogonal multiple access (NOMA) capability, and queue stability constraints. We formulate the problem as a network utility maximization in which Lyapunov framework is used to decomp...
