Description
移動体電気通信技術により、世界はますます接続されてネットワーク化された社会に向かっている。既存の無線ネットワークと比較すると、次世代のシステム及び無線通信技法は、はるかに広い範囲のユースケース特徴に対応し、より複雑かつ高度な範囲のアクセス要件及び柔軟性を提供する必要がある。
本開示は、マルチ入力マルチ出力(MIMO)技術のための干渉測定において受信ビームの衝突を緩和する方法、システム、及びデバイスに関する。ロングタームエボリューション(LTE)のためのMIMO技術の進化に伴い、無線通信システムにおける送信端及び受信端は、概して、情報をより高レートで送信及び受信するために複数のアンテナを含む。MIMO技術の一つの利益は、送信端及び受信端がビームフォーミング能力を有することが可能になり、情報を受信するためにビームを特定の方向に位置合わせすることができることである。ビームフォーミング技術を用いることで、正確な干渉測定により、送信端及び受信端がシステム性能を十分に実現することが可能になる。既存の干渉測定技術では、IMRが位置する直交周波数分割多重(OFDM)シンボルに他のチャネル又は信号が存在する可能性があり、受信ビームの衝突が生じるおそれがある。
(1)基地局は、空間多重化によりRIデータを伝送するために、推奨されるRIを複数の層として使用し、同時にプロトコルに指定された層マッピング方法を使用する。
(2)信号は、推奨されるPMIで事前にコード化される。
(3)ユーザ機器(UE)又は端末によって、干渉及び雑音が測定される。

- 不整合条件に基づいて、送信端を第1のモードまたは第2のモードのうちの一方で選択的に動作させることを含む無線通信方法であって、
前記不整合条件の不在を検出した場合には、前記送信端が前記第1のモードで伝送し、前記第1のモードにおいて、前記送信端が、データ又は制御伝送と同じ時間単位で干渉評価のための伝送リソースをスケジュールし、
前記不整合条件を検出した場合には、前記送信端が前記第2のモードで伝送し、前記第2のモードにおいて、干渉を決定するための前記伝送リソースが、データ又は制御伝送とは異なる時間単位を占有するようにスケジュールされ、
前記不整合条件は、前記送信端が、受信端によって提供されるチャネル品質インディケータ(CQI)に基づき、変調及び符号化方式(MCS)を正確に決定できないということを示し、
信号対干渉雑音比(SINR)が閾値未満である場合、又は、干渉測定を実行するための1つの受信ビームと、データ又は制御伝送を受信するための別の受信ビームとを、同じ時間単位で受信端が有することができない場合には、前記送信端は前記MCSを正確に決定できない、
