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)…
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…
Rate Splitting Multiple Access for Semi-Grant-Free Transmissions
Hongwu Liu, Theodoros A. Tsiftsis, Bruno Clerckx +3
Enabled by hybrid grant-based (GB) and grant-free (GF) transmission techniques, GF users of internet of things (IoT) devices and massive machine-type communications (mMTC) meet opp…
A 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…
Metasurface-Coated Devices: A New Paradigm for Energy-Efficient and Secure 6G Communications
Theodoros A. Tsiftsis, Constantinos Valagiannopoulos, Hongwu Liu +2
The sixth-generation (6G) era comes with the challenge of offering highly energy-efficient and autonomous communications securely. In this direction, we report energy efficiency (E…
Amplify-and-Forward Full-Duplex Relay with Power Splitting-Based SWIPT
Hongwu Liu, Kyung Sup Kwak
This paper proposes a virtual harvest-transmit model and a harvest-transmit-store model for amplify-and-forward full-duplex relay (FDR) networks with power splitting-based simultan…
Power Splitting for Full-Duplex Relay with Wireless Information and Power Transfer
Hongwu Liu, Kyeong Jin Kim, Kyung Sup Kwak
This paper investigates power splitting for full-duplex relay networks with wireless information and energy transfer. By applying power splitting as a relay transceiver architectur…
Relay Control for Full-Duplex Relaying with Wireless Information and Energy Transfer
Hongwu Liu, Kyeong Jin Kim, H. Vincent Poor +1
This study investigates wireless information and energy transfer for dual-hop amplify-and-forward full-duplex relaying systems. By forming energy efficiency (EE) maximization probl…
