Description
非グループ化ベース(non−grouping based)のビームレポートでは、次のレポートパラメータがサポートされている:
・ビーム測定のために設定された送信(Tx)ビームの最大数:K=64
・1つのインスタンス(instance)でレポートされる設定されたTxビームの最大数:N_max=2、4、ここで、N(N≦N_max、N=1、2、3、4)ビームのサブセットは、gNBによって選択され、かつUEに示す(シグナリングメカニズムは今後の検討課題である)ことができる。
・1つのレポートインスタンスで複数のビームがレポートされる場合、差分L1−参照信号受信電力(L1−RSRP:Reference Signal Received Power)がレポートされる。参照されるのは、当該レポートインスタンスで最大のL1−RSRPである。
・ビット幅:1dBのステップサイズで−140dBm〜−44dBm範囲のL1−RSRPでは7ビット(Long タームエボリューション(LTE:Long Term Evolved)と類似)、差分L1−RSRPでは4ビットである。
ビーム管理のためにレポートするL1−RSRPおよび/またはビームリソースインジケータ(たとえば、チャネル状態情報参照信号(CSI−RS:Channel State Information Reference Signal)または同期信号ブロック(SSB:Synchronization Signal Block)のインジケータ)では、次のアップリンク(UL:uplink)チャネルがサポートされている:Short 物理アップリンク制御チャネル(Short PUCCH(Short Physical Uplink Control Channel)、またはS−PUCCH)、Long PUCCH(L−PUCCH:long−PUCCH)、および物理アップリンク共有チャネル(PUSCH:Physical Uplink Shared Channel)。上記のチャネルのビーム管理では、次のレポートタイプがサポートされている:
・周期的−Long PUCCHとShort PUCCHをサポート
・半永続的−Long PUCCH、Short PUCCH及びPUSCHをサポート
・非周期的−PUSCHとShort PUCCHをサポート
