Priority Random Access and Power Control for NOMA-ALOHA in Heterogeneous mMTC
Wenbo Fan, Pingzhi Fan, Zilong Liu
This paper presents a novel priority random access (PRA) non-orthogonal multiple access assisted ALOHA, called PRA-NA, to provide access priority for machine-type devices (MTDs) wi…
Enabling Flexible AFDM-ISAC Design: When Ambiguity Shaping Meets PAPR Control
Lingsheng Meng, Yong Liang Guan, Zilong Liu +2
Affine frequency division multiplexing (AFDM) has emerged as an enabling waveform for integrated sensing and communication (ISAC) due to its intrinsic chirp signaling nature. Never…
A Unified Multicarrier Waveform Framework for Next-generation Wireless Networks: Principles, Performance, and Challenges
Xingyao Zhang, Haoran Yin, Yanqun Tang +7
Next-generation wireless networks require enhanced flexibility, efficiency, and reliability in physical layer waveform design to address the challenges posed by heterogeneous chann…
Multi-Functional Chirp Signalling for Next-Generation Multi-Carrier Wireless Networks: Communications, Sensing and ISAC Perspectives
Zeping Sui, Qu Luo, Zilong Liu +6
To meet the increasingly demanding quality-of-service requirements of the next-generation multi-carrier mobile networks, it is essential to design multi-functional signalling schem…
