A Novel Perspective on Multiple Access in 5G Network: Framework and Solutions

5G, which puts forward great demands for capacity, rate, latency, connectivity and energy consumption, guides humans to the era of Internet of everything. It aims to construct a reliable wireless network to connect all applications and services. Nevertheless, due to the differentiated wireless environments and diverse requirements, the massive radio resources present great challenges for efficient and flexible multiple access. To tackle this problem, in this article, we provide a novel perspective on multiple access and propose a framework together with both off-line and on-line solutions.
