Abstract:
(EN) This user terminal has: a control unit that determines a blank resource area set associated to a prescribed bandwidth part (BWP); and a transmission/reception unit that sends and/or receives taking into consideration said blank resource area. The control unit is characterized by assuming one out of (1) to (3) and determining the blank resource area. (1) The entire BWP bandwidth is the blank resource area during a prescribed time period. (2) Part of the prescribed BWP bandwidth is the blank resource area during a prescribed time period. (3) The blank resource area is not included in the prescribed BWP during a prescribed time period. As a result of the present invention, reduction in communication throughput can be suppressed even when performing control on the basis of BWP.
(FR) L'invention concerne un terminal utilisateur qui comprend : une unité de commande qui détermine un ensemble de zones de ressource vierge associé à une partie de bande passante prescrite (BWP) ; et une unité d'émission/réception qui envoie et/ou reçoit en tenant compte de ladite zone de ressource vierge. L'unité de commande est caractérisée en supposant que l'un parmi (1) à (3) et en déterminant la zone de ressource vierge. (1) La totalité de la bande passante BWP est la zone de ressource vierge pendant une période de temps prescrite. (2) Une partie de la bande passante BWP prescrite est la zone de ressource vierge pendant une période de temps prescrite. (3) La zone de ressource vierge n'est pas incluse dans la BWP prescrite pendant une période de temps prescrite. Grâce à la présente invention, la réduction du débit de communication peut être supprimée même en effectuant une commande sur la base de la BWP.
(JA) 本発明の一態様に係るユーザ端末は、所定の帯域幅部分(BWP:Bandwidth part)に関連して設定されるブランクリソース領域を判断する制御部と、当該ブランクリソース領域を考慮して送信及び/又は受信処理を行う送受信部と、を有し、前記制御部は、以下の(1)から(3)のいずれかを想定して前記ブランクリソース領域を判断することを特徴とする:(1)所定の期間において、前記BWPの帯域幅全体が前記ブランクリソース領域である、(2)所定の期間において、前記所定のBWPの帯域幅の一部が前記ブランクリソース領域である、(3)所定の期間において、前記所定のBWPには含まれない。本発明の一態様によれば、BWPに基づく制御を行う場合であっても、通信スループットの低下などを抑制できる。
