内容提要Outline of the Talk:

OTFS-NOMA: An Efficient Approach for Exploiting Heterogenous User Mobility Profiles  

In this talk, we will focus on a challenging communication scenario, in which   users have  heterogenous mobility profiles, e.g., some users are moving at high speeds and some users  are static.  A new non-orthogonal multiple-access (NOMA) transmission protocol that incorporates orthogonal time frequency space (OTFS) modulation is described, where users with different mobility profiles are grouped together for the implementation of NOMA.  We will show that both the high-mobility and the low-mobility users benefit from the application of OTFS-NOMA. In particular, the use of NOMA allows  the spreading of  the high-mobility users' signals over a large amount of time-frequency resources, which enhances the OTFS resolution and improves the detection reliability. In addition, OTFS-NOMA ensures that   low-mobility users have access to   bandwidth resources which  in conventional OTFS-orthogonal multiple access (OTFS-OMA) would be solely occupied by the high-mobility users. Thus, OTFS-NOMA improves the spectral efficiency and reduces latency. Some important future directions about OTFS-NOMA will be also discussed at the end of this talk.
