Non-Linear Age of Information: An Energy Efficient Receiver-Centric Approach
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang
The age of information (AoI) performance metric for point-to-point wireless communication systems is analytically studied under Rician-faded channels and when the receiver is equip…
Joint Task Offloading and Resource Allocation for IoT Edge Computing with Sequential Task Dependency
Xuming An, Rongfei Fan, Han Hu +3
Incorporating mobile edge computing (MEC) in the Internet of Things (IoT) enables resource-limited IoT devices to offload their computation tasks to a nearby edge server. In this p…
Semi-Blind Multiuser Detection Under the Presence of Reconfigurable Intelligent Surfaces
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang +2
A multiuser multiple-input multiple-output wireless communication system is analytically studied, which operates with the aid of a reconfigurable intelligent surface (RIS). The int…
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…
Backscatter Sensors Communication for 6G Low-powered NOMA-enabled IoT Networks under Imperfect SIC
Manzoor Ahmed, Wali Ullah Khan, Asim Ihsan +3
The combination of non-orthogonal multiple access (NOMA) using power-domain with backscatter sensor communication (BSC) is expected to connect a large-scale Internet of things (IoT…
