PHYSICAL DOWNLINK SHARED CHANNEL MUTING ON CELL-SPECIFIC REFERENCE SYMBOLS LOCATIONS FOR NON-SERVING CELLS

摘要

In a wireless telecommunications system having plural base station (401, 402, 403) and plural mobile user equipment units (411, 412, 413), a primary serving base station transmits Physical Downlink Shared Channel (PDSCH) with zero energy (i.e., muted PDSCH) on the inter-cell CRS Resource Element (RE) location. 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 identifications (IDs) of all Coordinated Multipoint Reception (CoMP) cells other than the cell ID i. The invention defines the Orthogonal Frequency Division Multiplexing (OFDM) symbols in which muting occurs.
