Interference-Constrained Pricing for D2D Networks

, 2016
The concept of device-to-device (D2D) communications underlaying cellular networks opens up potential benefits for improving system performance but also brings new challenges, such as interference management. In this paper, we propose a pricing framework

Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...

Changed Minds and L2 Motivation: Reflections of Japanese EFL Students Living, Laboring and Learning in Vietnam

International Journal of Applied Linguistics, EarlyView.
ABSTRACT English as a lingua franca (ELF) is increasingly used for communication in many EFL contexts, including Vietnam. Although Japan and Vietnam have a long history of economic cooperation, for practical reasons, English typically functions as the medium of communication between the two groups. This study examines Japanese expats who had studied or

Modeling and Analysis of Clustered D2D Millimeter-Wave Communications

, 2018
This paper investigates the performance of millimeter wave communications in clustered device-to-device (D2D) networks. The locations of D2D transceivers are modeled as a Poisson Cluster Process. In each cluster, the active D2D receiver (D2D-Rx) utilizes

Entangled Discourses and Realities of English: Japanese Undergraduates’ Everyday Online and Offline Language Experiences

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Focusing on the narratives of two Japanese undergraduate students, this article examines their everyday experiences of using and learning English, situated within entangled relations of power. Drawing on the Foucauldian notion of discourse, the study reveals how multiple power/knowledge systems—such as native speakerism, prescriptivism ...

Generative Semantic Communication for Efficient Utilization of Satellite Resources in 6G

International Journal of Satellite Communications and Networking, Volume 44, Issue 4, Page 368-377, July/August 2026.
ABSTRACT In this paper, a two‐stage resource allocation framework is proposed for generative semantic communication (GSC)–enabled multibeam satellite systems. By integrating semantic compression and generative artificial intelligence, GSC enables efficient downlink transmission by allowing users to reconstruct content from compressed semantic prompts ...

Enhancing Content Caching in D2D Networks: A Stackelberg Game Approach With Wireless Energy Transfer and Social Awareness

IEEE Access
In a cache-enabled device-to-device (D2D) network, cooperative D2D caching holds promise for reducing data traffic and overall waiting time. However, the act of content caching and transmission can impose a drain on battery power, thereby diminishing ...
