主要内容：

Future fifth generation (5G) wireless networks are expected to support very diverse traffics with much tighter requirements, such as massive connectivity, better quality of service, higher throughput, lower latency, or lower control signaling overhead, which should be met with new waveform and access designs. In general, multiple access technique allows a number of users to share the same transmission medium without interference or with tolerable interference. Different from conventional orthogonal multiple access (MA) techniques, non-orthogonal MA techniques can accommodate much more users via non-orthogonal resource allocation. In this talk, basic principles of orthogonal and non-orthogonal MA techniques shall be firstly discussed, then two promising non-orthogonal MA techniques, i.e. power-domain non-orthogonal MA and sparse code MA (SCMA) shall be investigated. Finally, other known non-orthogonal MA techniques shall be briefly reviewed and compared.
