Uplink Contention Based SCMA for 5G Radio Access
Kelvin Kar Kin Au,Liqing Zhang,Hosein Nikopour,Eric Yi,Alireza Bayesteh,Usa Vilaipornsawai,Jianglei Ma,Peiying Zhu +7 more
TL;DR: In this paper, an uplink contention-based sparse code multiple access (SCMA) design is proposed as a solution for 5G networks, which can provide low signaling overhead, low delay, and support of massive connectivity.
Proceedings ArticleDOI
SCMA for downlink multiple access of 5G wireless networks
Hosein Nikopour,Eric Yi,Alireza Bayesteh,Kelvin Kar Kin Au,Mark Andrew Hawryluck,Hadi Baligh,Jianglei Ma +6 more
TL;DR: A technique is developed to enable multi-user SCMA (MU-SCMA) for downlink wireless access designed to improve the downlink throughput of a heavily loaded network and the advantage of SCMA spreading for lightly loaded networks is evaluated.
Proceedings ArticleDOI
Blind detection of SCMA for uplink grant-free multiple-access
TL;DR: The analysis and performance evaluation confirm the proposed SCMA-based blind reception solution is a promising technology to enable massive connectivity for grant-free multiple-access transmission mode in future wireless networks.
