The method is: in the embodiments of the present invention, a network side determines a mapping relationship between a PDSCH transmission point and a zero-power CSI-RS for UE, and the UE does not receive a PDSCH over a zero-power CSI-RS resource which corresponds to a cell currently transmitting the PDSCH and measures an interference and still receives the PDSCH over a zero-power CSI-RS resource which corresponds to a cell not currently transmitting the PDSCH and measures an interference, thereby ensuring that the UE can accurately measure the interference and further improving the accuracy of CQI estimation; furthermore, the signalling overhead required for realizing the technical solution of the present invention is very small, only some RRC signalings are required, and a dynamic signaling can reuse a current signaling to the greatest extent, in this way, the compatibility of the system is effectively improved and the complexity of implementation is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for determining PDSCH transmission resources","description":"The present invention relates to the field of communications, and disclosed are a method and device for determining a PDSCH transmission resource.
