N2 - Conventionally, it was thought that outage probability error floors are unavoidable in uplink non-orthogonal multiple access (NOMA) regardless which type of successive interference cancellation (SIC) is adopted. However, a recent work breaks such myths by introducing the concept of hybrid SIC, which dynamically chooses the decoding order according to the users' channel conditions and quality of service requirements. However, there is still a limitation in this existing work that the error floors can only be avoidable under a stringent condition on users' target rates. To this end, this letter proposes a new hybrid SIC scheme by exploiting the benefit of power control, which guarantees no error floor without any conditions on users' target rates.
