Description
・ TRP内モビリティ
・ TRP間モビリティ
・ NR eNB間モビリティ
3GPP R2−162762では、カバレッジが時間及び空間の両方の変動に対してより敏感となる可能性があるため、ビームフォーミングに純粋に依存し、より高い周波数で動作するシステムの信頼性は挑戦的なものとなる可能性がある。その結果、その狭いリンクのSINRは、LTEの場合よりもはるかに急速に低下する可能性がある。
以上、種々の態様に関連して本発明を説明したが、本発明は、さらに改良可能であることが了解される。本願は、概して本発明の原理に従うと共に、本発明が関係する技術分野における既知で慣習的な実施となるような本開示からの逸脱を含む本発明の任意の変形、使用、又は適応を網羅することを意図している。
