| 摘要 |
The present invention relates to a signal processing method in a spectrum sharing wireless communication system wherein, in an environment where, among UEs included in a licensed band (e.g., LTE) network, licensed band (e.g., LTE) data is transmitted/received by using an unlicensed band (e.g., WiFi), a zero powered resource element (ZPRE) pattern and an allocation method are proposed, and the existence or not of an unlicensed band (e.g., WiFi) interference signal is identified by using the ZPRE, and the interference strength, the number of licensed band (e.g., LTE) symbols affected by the interference are confirmed and processed, and thus a high interference signal impact by means of a short unlicensed band (e.g., WiFi) signal transmitted by an unlicensed band (e.g., WiFi) device adjacent to a UE is minimized, and decoding is made possible in order to enhance reception performance in an interference environment. |
