Title:
ノンサービングセルに対するセル固有参照シンボルローケーションでの物理的ダウンリンク共用チャネルミュート
Document Type and Number:
Japanese Patent JP2013524646
Kind Code:
A
Abstract:
The primary serving base station transmits PDSCH with zero energy on the inter-cell CRS resource element location. This is called mute PDSCH. Within the first Physical Resource Block (PRB 0), the RE positions in the frequency domain are indexed between 0 and 11. The muted PDSCH RE positions per antenna port are computed using the cell IDs of all CoMP cells other than the cell ID i. The invention defines the Orthogonal Frequency Division Multiplexing (OFDM) symbols in which muting occurs.
