Abstract
(EN) This user terminal has: a receiver for measuring received power at a frequency where channel sensing is applied; and a controller for performing transmission at the frequency on the basis of sensing performed in a random time within a contention window size (CWS) based on the measurement. According to one aspect of the present disclosure, appropriate communication can be performed in an unlicensed band.
(FR) Le terminal utilisateur de l'invention possède : une unité réception qui calcule une puissance de réception à une fréquence à laquelle une détection de canaux est appliquée ; et une unité commande qui effectue une émission à ladite fréquence, sur la base d'une détection dans une durée aléatoire à l'intérieur d'une taille de fenêtre de contention (CWS) selon ledit calcul. En outre, selon un mode de réalisation de l'invention, il est possible d'effectuer une communication adéquate dans une bande sans licence.
(JA) ユーザ端末は、チャネルのセンシングが適用される周波数において受信電力を測定する受信部と、前記測定に基づくコンテンションウィンドウサイズ(CWS)内のランダム時間内のセンシングに基づいて、前記周波数における送信を行う制御部と、を有する。本開示の一態様によれば、アンライセンスバンドにおいて適切な通信を行うことができる。
