The discussion in this talk includes the potential new challenges, requirements, and opportunities for the next generation of multiple access in these new scenarios.

The next generation of wireless communication networks requires continuous evolutions of multiple access (MA) techniques due to the demand for ubiquitous connections of everything besides humans. In the 5G system, many potential MA techniques have been considered.

For example, non-orthogonal multiple access (NOMA) has been discussed deeply as a sophisticated method of sharing access resources to accommodate more users compared with the traditional orthogonal way. And grant free mechanisms, including configured grant and 2-Step RACH, have been successfully promoted to NR standard as an efficient way to reduce the access latency and the signaling overhead.

All of these techniques still need to be evolved with combination of new frequency bands, more advanced MIMO techniques, as well as novel AI technologies, to fulfill the requirements of multiple access for 6G scenarios, such as critical MTC connections for industrial applications, super-massive connections with low cost devices, ubiquitous connectivity with integrated non-terrestrial networks (NTN), as well as high-efficient multiple access for mixed services.

Moreover, as Network Sensing and Network AI are becoming the typical beyond communication new usage scenarios of the future mobile networks, new multiple access paradigm might be needed for such task oriented communications. 

The discussion in this talk includes the potential new challenges, new requirements, and new opportunities for the next generation of multiple access in these new scenarios.
