On Age of Information and Energy‐Transfer in a STAR‐RIS‐Assisted System

IET Communications, Volume 19, Issue 1, January/December 2025.
This paper explores a wireless sensor network that simultaneously charges energy harvesting devices and minimizes the Age of Information (AoI) for time‐sensitive users. A multi‐antenna base station and simultaneously‐transmitting‐and‐reflecting reconfigurable intelligent surface (STAR‐RIS) are used to optimize power transmission and status updates ...

Resource allocation for coexistence of eMBB and bursty URLLC based on queueing with preemption

Journal of Information and Intelligence
Enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC) are two critical services in 5G mobile networks. While there has been extensive research on their coexistence, few studies have considered the impact of bursty URLLC on

UAVs‐Assisted Low‐Bit Quantized CF‐mMIMO Systems With MmWave Communications Under MRC Detection

IET Communications, Volume 19, Issue 1, January/December 2025.
ABSTRACT The cell‐free massive multiple input multiple output (CF‐mMIMO) approach, due to its high coverage and the ability to attenuate the large‐scale fading impacts in wireless communications, has drawn a lot of attention. Additionally, because of their movement ability, low power, and low‐cost employed infrastructures, unmanned aerial vehicles ...

Simulation and Analysis of Mobile Access (SAMA): Cellular Radio Access Network Simulator and Performance Evaluator Applied to 5G

IET Communications, Volume 19, Issue 1, January/December 2025.
This paper presents SAMA, a simulator for 5G Radio Access Networks (RAN), designed to evaluate the performance of different network configurations. The diagram illustrates the simulator's workflow: from inputs such as base station (BS) and user equipment (UE) arrangements, SAMA simulates resource allocation and scheduling, considering interference.

IRS‐Assisted Communication in 3D Stochastic Geometry Utilizing Large Antenna Transmitters With Hardware Impairments

IET Communications, Volume 19, Issue 1, January/December 2025.
This study proposes a 3D stochastic geometry model for intelligent reflecting surface (IRS)‐assisted communication systems utilizing large antenna transmitters with cylindrical array configurations. The model incorporates hardware impairments and evaluates spectral efficiency under both ideal and non‐ideal conditions.

Multi-Objective Optimisation of URLLC-Based Metaverse Services

, 2023
Metaverse aims for building a fully immersive virtual shared space, where the users are able to engage in various activities. To successfully deploy the service for each user, the Metaverse service provider and network service provider generally localise the user first and then support the communication between the base station (BS) and the user.

Reducing the Peak to Average Power Ratio of UFMC Waveform for Beyond 5G System Using Hybrid SLM+PTS+RNN Algorithms

IET Communications, Volume 19, Issue 1, January/December 2025.
This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.
