Throughout the development of communication systems, the diversified combination of different technologies always makes the network more and more "heavy", e.g., heavy deployment, heavy investment, heavy operation and maintenance(O&M), which has brought great challenges to the network applications. Therefore, 5G system should be designed as an easy network, characterized by easy deployment, low investment, easy O&M and delightful experience. According to this discussion, this paper identifies several technical components which can make up an Easy Network for 5G air interface, and the details of the Easy Network features are analyzed. Our study aims to make efforts to promote a healthy and sustainable environment for 5G at the beginning of the system design.展开更多

To meet the 5G requirements on the numberof connections and spectral efficiency, uplink NMA is becoming an important candidate technology and has been extensively stud-ied in 3GPP. A number of uplink NMA schemes from different industrial companies have been proposed in recent 3GPP meet-ings. In terms of their basic technique principles, this paper classifies these NMA schemes into three categories, namely: scram-bling based NMA schemes, interleaving based NMA schemes, and spreading based NMA schemes. Moreover, the key characteris-tics of these schemes are summarized, and the detailed introduction of each scheme is provided according to the comprehensivesurvey of the latest progress in 3GPP 5G standardization work.展开更多
