International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

Radio Link Enabler for Context-aware D2D Communication in Reuse Mode
, 2017 Device-to-Device (D2D) communication is considered as one of the key technologies for the fifth generation wireless communication system (5G) due to certain benefits provided, e.g. traffic offload and low end-to-end latency. A D2D link can reuse resource

Energy Efficiency and Sum Rate when Massive MIMO meets Device-to-Device Communication
, 2015 This paper considers a scenario of short-range communication, known as device-to-device (D2D) communication, where D2D users reuse the downlink resources of a cellular network to transmit directly to their corresponding receivers.

Japanese Women's Attitudes Toward Learning Languages Other Than English in the Era of Global English
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study on female Japanese learners of the Korean language is situated in the centuries‐long anti‐Korean sentiments in Japan, the global popularity of the Korean Wave, particularly among women, and the essentialized image of socially marginalized young Japanese women who study English with romantic desires for Western men.
