Next-generation multi-user communication systems are expected to provide considerable gains in the performance space with respect to current telecommunication infrastructure. To cite but a few aspects, they shall have the capacity in fixed and high-mobility scenarios to efficiently handle a large number of users (human or machine) with disparate data rates, different activity patterns, or varying latency and quality of service, as well as the capability to operate under internetwork interference, in user overloaded regimes or to control signal formats to fulfil diverse performance criteria. The coordinated project MAYTE will contribute to the picture above through two complementary objectives. Firstly, to develop suitable signal designs for next-generation networks oriented toward the optimization of key performance indicators. Three research sublines will be considered under this scope: (i) efficient optimization of the spectral properties of precoded MIMO communication waveforms for advanced signals such as orthogonal time-frequency-space (OTFS) to improve system co-existence in terms of out-of band radiation; (ii) design and optimization of next-generation multiple-access (NGMA) based on multiple-antenna signaling schemes for interference-resistant dense networks with a large number of users ; and (iii) optimization of ultra-reliable low-latency communication (URLLC) schemes based on short packet design. Secondly, to design and optimize signal and information processing schemes and tools for interference management and data analysis in next-generation networks. Three research sublines will be considered under this scope: (i) efficient design of multiple-antenna interference cancellation and interference-resistant schemes at the receiver side and development of asymptotic analyses; (ii) development and implementation of signal processing techniques to manage self-interference under simultaneous transmission and reception to improve spectral efficiency and reduce transmission latency; and (iii) to develop tools for informative learning from data beyond second order statistics toward improved signal processing algorithms and performance evaluation in communication networks.
