以下、SL-SSBを送信するためのSL-SSBリソースを指定する情報を通知する方法の例2を図8を参照して説明する。例2では、例1と同様に、上述の項目1~項目8のうちのいずれか1つ、又は上述の項目1~項目8のうちの複数がユーザ装置20に通知(又は規定)されてもよい。ユーザ装置20は、通知されたTDD configuration、又はDL-SSBの位置に基づいて、一部のSL-SSBリソースを除外する。この除外する例が図8に示されている。例えば、UL以外の領域と重なったSL送信用のリソースが除外されてもよく、送信されるSSBのシンボルと重なったSL送信用のリソースが除外されてもよく、又は送信されるSSBのシンボル以外の領域と重なったSL送信用のリソースが除外されてもよい。
次に、これまでに説明した処理及び動作を実行する基地局装置10及びユーザ装置20の機能構成例を説明する。基地局装置10及びユーザ装置20は上述した実施例を実施する機能を含む。ただし、基地局装置10及びユーザ装置20はそれぞれ、実施例の中の一部の機能のみを備えることとしてもよい。
図10は、基地局装置10の機能構成の一例を示す図である。図10に示されるように、基地局装置10は、送信部110と、受信部120と、設定部130と、制御部140とを有する。図10に示される機能構成は一例に過ぎない。本発明の実施の形態に係る動作を実行できるのであれば、機能区分及び機能部の名称はどのようなものでもよい。
図11は、ユーザ装置20の機能構成の一例を示す図である。図11に示されるように、ユーザ装置20は、送信部210と、受信部220と、設定部230と、制御部240とを有する。図11に示される機能構成は一例に過ぎない。本発明の実施の形態に係る動作を実行できるのであれば、機能区分及び機能部の名称はどのようなものでもよい。
上記実施形態の説明に用いたブロック図(図10及び図11)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。
以上、説明したように、本発明の実施の形態によれば、サイドリンクにおける同期信号及びブロードキャスト情報を含む複数のブロックであって、該複数のブロックのうちの各ブロックには、複数のビームの1セットのうちの対応するビームが適用される、複数のブロック、を送信するリソース群を指定する情報を受信する受信部と、前記リソース群を指定する情報に従って、前記複数のブロックを送信するための複数のリソースを選択する制御部と、前記選択された複数のリソースを使用して他のユーザ装置に前記サイドリンクにおける同期信号及びブロードキャスト情報を含む複数のブロックを送信する送信部とを有するユーザ装置が提供される。
以上、本発明の実施の形態を説明してきたが、開示される発明はそのような実施形態に限定されず、当業者は様々な変形例、修正例、代替例、置換例等を理解するであろう。発明の理解を促すため具体的な数値例を用いて説明がなされたが、特に断りのない限り、それらの数値は単なる一例に過ぎず適切な如何なる値が使用されてもよい。上記の説明における項目の区分けは本発明に本質的ではなく、2以上の項目に記載された事項が必要に応じて組み合わせて使用されてよいし、ある項目に記載された事項が、別の項目に記載された事項に(矛盾しない限り)適用されてよい。機能ブロック図における機能部又は処理部の境界は必ずしも物理的な部品の境界に対応するとは限らない。複数の機能部の動作が物理的には1つの部品で行われてもよいし、あるいは1つの機能部の動作が物理的には複数の部品により行われてもよい。実施の形態で述べた処理手順については、矛盾の無い限り処理の順序を入れ替えてもよい。処理説明の便宜上、基地局装置10及びユーザ装置20は機能的なブロック図を用いて説明されたが、そのような装置はハードウェアで、ソフトウェアで又はそれらの組み合わせで実現されてもよい。本発明の実施の形態に従って基地局装置10が有するプロセッサにより動作するソフトウェア及び本発明の実施の形態に従ってユーザ装置20が有するプロセッサにより動作するソフトウェアはそれぞれ、ランダムアクセスメモリ(RAM)、フラッシュメモリ、読み取り専用メモリ(ROM)、EPROM、EEPROM、レジスタ、ハードディスク(HDD)、リムーバブルディスク、CD-ROM、データベース、サーバその他の適切な如何なる記憶媒体に保存されてもよい。
