Abstract: front page image
(EN)This invention is directed to achievement of optimum CFI control and improvement of PDSCH transmission efficiency in an environment where a cross carrier scheduling is applied. Regarding macro-UE2 to which a cross carrier scheduling is applied, the PDSCH start position of CC1 on which PDCCH is transmitted is dynamically controlled, and the PDSCH start position of CC2 on which no PDCCH is transmitted is quasi-statically controlled. Regarding pico-UE2 to which a cross carrier scheduling is applied, the PDSCH start position of CC2 on which PDCCH is transmitted is dynamically controlled, and the PDSCH start position of CC1 on which no PDCCH is transmitted is dynamically controlled.
(FR)Cette invention permet d'obtenir une commande optimale du CFI et d'améliorer l'efficacité de l'émission du PDSCH dans un environnement où un ordonnancement croisé des porteuses est appliqué. En ce qui concerne le macro UE2 auquel est appliqué un ordonnancement croisé des porteuses, la position de début de PDSCH de la CC1 où le PDCCH est émis est commandée dynamiquement, et la position de début de PDSCH de la CC2 où aucun PDCCH n'est émis est commandée de façon presque statique. En ce qui concerne le pico UE2 auquel est appliqué un ordonnancement croisé des porteuses, la position de début de PDSCH de la CC2 où le PDCCH est émis est commandée dynamiquement, et la position de début de PDSCH de la CC1 où aucun PDCCH n'est émis est commandée dynamiquement.
(JA) クロスキャリアスケジューリングが適用される環境下において最適なCFI制御を実現し、PDSCHの送信効率を向上すること。クロスキャリアスケジューリングが適用されるマクロUE2に関して、PDCCHを送信するCC1のPDSCH開始位置をダイナミックに制御し、PDCCHを送信しないCC2のPDSCH開始位置を準静的に制御し、クロスキャリアスケジューリングが適用されるピコUE2に関して、PDCCHを送信するCC2のPDSCH開始位置をダイナミックに制御し、PDCCHを送信しないCC1のPDSCH開始位置をダイナミックに制御する。
