A New QoS-Guarantee Strategy for NOMA Assisted Semi-Grant-Free Transmission
Z. Ding, R. Schober, H. V. Poor
Semi-grant-free (SGF) transmission has recently received significant attention due to its capability to accommodate massive connectivity and reduce access delay by admitting grant-…
Physics-based Modeling and Scalable Optimization of Large Intelligent Reflecting Surfaces
Marzieh Najafi, Vahid Jamali, Robert Schober +1
Intelligent reflecting surfaces (IRSs) have the potential to transform wireless communication channels into smart reconfigurable propagation environments. To realize this new parad…
A Simple Design of IRS-NOMA Transmission
Z. Ding, H. V. Poor
This letter proposes a simple design of intelligent reflecting surface (IRS) assisted non-orthogonal multiple access (NOMA) transmission, which can ensure that more users are serve…
OTFS-NOMA: An Efficient Approach for Exploiting Heterogenous User Mobility Profiles
Zhiguo Ding, Robert Schober, Pingzhi Fan +1
This paper considers 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.…
