無線ネットワークにおいて、物理ダウンリンク・チャネルにおけるリソース要素をパンクチャすることによってダウンリンク信号におけるタイミング・オフセットのインパクトを低減すること

Title:

Document Type and Number:

Japanese Patent JP2013530571

Kind Code:

A

Abstract:

When performing interference cancellation on selected information (e.g., synchronization signals, certain broadcast signals, etc.) through cross correlation, symbol periods of signals being combined will generally match up. Slight mismatches will generally produce negligible impact on interference cancellation. However, where the mismatch is severe due to significant timing offsets, serious performance degradation may occur, particularly when timing offsets are sufficiently large as to overlap data portions of a transmission. By selectively puncturing resource elements prior to the selected information and/or after the selected information, the selected information may be protected and allow for interference cancellation even in cases of large timing offsets.
