Multi-Beam Opportunistic Rate-Splitting Multiple Access in MEC-Assisted Vehicular Networks

The evolution of sixth-generation (6G) communication technologies and intelligent transportation has driven vehicular networks toward low latency and high connectivity. Mobile edge computing (MEC) has been widely recognized as a promising paradigm for supporting the diverse service requirements of vehicular networks. H...

Joint Timing Offset Estimation, User Activity Detection, and Channel Estimation for Asynchronous OTFS-Based Grant-Free Random Access

Grant-free random access (GFRA) is a key enabler for massive machine-type communications (mMTC) in future wireless networks. However, supporting massive access under high mobility and asynchronous transmissions remains a fundamental challenge, especially for orthogonal time–frequency space (OTFS) modulation, where timi...
