Abstract
Description
NRでは、ライセンスキャリア(ライセンスバンド内のキャリア)だけでなく、アンライセンスキャリア(アンライセンスバンド内のキャリア)を通信に用いることが検討されている。ライセンスキャリアは、一事業者に専用に割り当てられた周波数のキャリアである。アンライセンスキャリアは、複数の事業者、RAT間などで共用する周波数のキャリアである。
また、NRでは、単一のDCIにより、複数のデータに対応する複数のPUSCHを複数の時間ユニットに渡ってスケジュールすること(マルチデータスケジューリング等ともいう)が検討されている。
第1の態様では、マルチデータスケジューリング用のDCIについて説明する。
図2は、第1の態様に係る第1のDCIに基づくマルチデータスケジューリングの一例を示す図である。なお、図2では、一つのDCIによりスケジューリングされる複数のTBの数nは、2であるものとするが、2以上であってもよい。
図3は、第1の態様に係る第2のDCIに基づくマルチデータスケジューリングの一例を示す図である。なお、図3では、一つのDCIによりスケジューリングされる複数のTBの数nは、2であるものとするが、2以上であってもよい。3以上のTBをスケジューリングする場合、TB#3以降の各TB#iについては、以下のTB#2をTB#iに読み替えればよい。図3では、図2との相違点を中心に説明する。
第2の態様では、マルチデータスケジューリング用の再送制御について説明する。
第1及び第2の態様では、PUSCHで送信される複数のTBのマルチデータスケジューリングについて説明したが、本実施形態は、PDSCHで送信される複数のTBのマルチデータスケジューリングにも適宜適用可能である。
以下、本開示の一実施形態に係る無線通信システムの構成について説明する。この無線通信システムでは、本開示の上記各実施形態に係る無線通信方法のいずれか又はこれらの組み合わせを用いて通信が行われる。
図6は、一実施形態に係る基地局の構成の一例を示す図である。基地局10は、制御部110、送受信部120、送受信アンテナ130及び伝送路インターフェース(transmission line interface)140を備えている。なお、制御部110、送受信部120及び送受信アンテナ130及び伝送路インターフェース140は、それぞれ1つ以上が備えられてもよい。
図7は、一実施形態に係るユーザ端末の構成の一例を示す図である。ユーザ端末20は、制御部210、送受信部220及び送受信アンテナ230を備えている。なお、制御部210、送受信部220及び送受信アンテナ230は、それぞれ1つ以上が備えられてもよい。
なお、上記実施形態の説明に用いたブロック図は、機能単位のブロックを示している。これらの機能ブロック(構成部)は、ハードウェア及びソフトウェアの少なくとも一方の任意の組み合わせによって実現される。また、各機能ブロックの実現方法は特に限定されない。すなわち、各機能ブロックは、物理的又は論理的に結合した1つの装置を用いて実現されてもよいし、物理的又は論理的に分離した2つ以上の装置を直接的又は間接的に(例えば、有線、無線などを用いて)接続し、これら複数の装置を用いて実現されてもよい。機能ブロックは、上記1つの装置又は上記複数の装置にソフトウェアを組み合わせて実現されてもよい。
なお、本開示において説明した用語及び本開示の理解に必要な用語については、同一の又は類似する意味を有する用語と置き換えてもよい。例えば、チャネル、シンボル及び信号(シグナル又はシグナリング)は、互いに読み替えられてもよい。また、信号はメッセージであってもよい。参照信号(reference signal)は、RSと略称することもでき、適用される標準によってパイロット(Pilot)、パイロット信号などと呼ばれてもよい。また、コンポーネントキャリア(Component Carrier(CC))は、セル、周波数キャリア、キャリア周波数などと呼ばれてもよい。
