DFT-p-FDMA Based Chirp Transmission in CP-OFDM for Unified ISAC Waveform Design
Fabrizio Carpi, Joonyoung Cho, Kyeong Jin Kim +1
We propose an integrated sensing and communications (ISAC) framework that supports chirp signal transmission in CP-OFDM-based multiple access communication systems, enabling effici…
Cognitive Radio-Inspired Rate-Splitting Multiple Access for Semi-Grant-Free Transmissions
Hongwu Liu, Kyeong Jin Kim, Theodoros A. Tsiftsis +3
In this paper, we propose a cognitive radio-inspired rate-splitting multiple access (CR-RSMA) scheme to assist semi-grant-free (SGF) transmissions in which a grant-based user (GBU)…
Outage Analysis of Aerial Semi-Grant-Free NOMA Systems
Hongjiang Lei, Chen Zhu, Ki-Hong Park +4
In this paper, we analyze the outage performance of unmanned aerial vehicles (UAVs)-enabled downlink non-orthogonal multiple access (NOMA) communication systems with the semi-grant…
Rate Splitting Multiple Access Aided Mobile Edge Computing in Cognitive Radio Networks
Hongwu Liu, Yinghui Ye, Zhiquan Bai +2
In this paper, we investigate rate splitting multiple access (RSMA) aided mobile edge computing (MEC) in a cognitive radio network. We propose a RSMA scheme that enables the second…
A New Rate Splitting Strategy for Uplink CR-NOMA Systems
Hongwu Liu, Zhiquan Bai, Hongjiang Lei +3
In uplink non-orthogonal multiple access (NOMA) channels, the existing cooperative successive interference cancellation (SIC) and power control (PC) schemes lack the capability of…
On Secure NOMA-Aided Semi-Grant-Free Systems
Hongjiang Lei, Fangtao Yang, Hongwu Liu +3
Semi-grant-free (SGF) transmission scheme enables grant-free (GF) users to utilize resource blocks allocated for grant-based (GB) users while maintaining the quality of service of…
