Proceedings ArticleDOI
Non-Orthogonal Multiple Access (NOMA) for Cellular Future Radio Access
TL;DR: It is shown that the downlink NOMA with SIC improves both the capacity and cell-edge user throughput performance irrespective of the availability of the frequency-selective channel quality indicator (CQI) on the base station side.
Proceedings ArticleDOI
System-level performance evaluation of downlink non-orthogonal multiple access (NOMA)
TL;DR: It is shown under multiple configurations that the system-level performance achieved by NOMA is superior to that for OMA, and key link adaptation functionalities of the LTE radio interface such as adaptive modulation and coding, time/frequency-domain scheduling, and outer loop link adaptation are shown.
Proceedings ArticleDOI
Concept and practical considerations of non-orthogonal multiple access (NOMA) for future radio access
TL;DR: System-level performance of NOMA is provided taking into account practical aspects of the cellular system and some of the key parameters and functionalities of the LTE radio interface such as adaptive modulation and coding (AMC) and frequency-domain scheduling.
Proceedings ArticleDOI
System-level performance of downlink NOMA for future LTE enhancements
TL;DR: It is shown that for both wideband and subband scheduling and both low and high mobility scenarios, NOMA can still provide a hefty portion of its expected gains even with error propagation, and also when the proposed simplified user grouping and power allocation are used.
