NGMN has had a central role in the definition of operator requirements, which has contributed significantly to the overall success of LTE. In the meantime, LTE has become a true global and mainstream mobile technology, and will continue to support the customer In non-orthogonal multiple access (NOMA) downlink, multiple data flows are superimposed in the power domain and user decoding is based on successive interference cancellation. NOMAs performance highly depends on the power split among the data flows and the Non-orthogonal multiple access (NOMA) represents a paradigm shift from conventional orthogonal multiple access (MA) concepts, and has been recognized as one of the key enabling technologies for 5G systems. In this paper, the impact of user pairing on the

The effect of the 675 insertion/deletion (4G/ 5G ) polymorphism of plasminogen activator inhibitor-1 (PAI-1) gene on the risk of venous thromboembolism (VTE) remains controversial. In this study, we performed a meta-analysis of published data regarding this issue. A There is considerable pressure to define the key requirements of 5G , develop 5G standards, and perform technology trials as quickly as possible. Normally, these activities are best done in series but there is a desire to complete these tasks in parallel so that commercial
