摘要： A CSI measurement method, a CSI acquisition method, a terminal and a network device are provided, to measure CSI. The terminal performs interference measurement to acquire initial interference measurement result, determine the CSI based on the initial interference measurement result and an interference measurement parameter configured by the network device, and then report the determined CSI to the network device. The interference measurement parameter is configured by the network device, so the interference measurement parameter configured by the network device is capable of reflecting an actual situation of interference information, and interference information acquired by the terminal based on the interference measurement parameter matches interference information for actual transmission in a better manner. As a result, it is able to improve a matching degree between the interference information acquired by the terminal and the interference information for the actual transmission, thereby to enable a network to select a more appropriate parameter for link adaptation.

摘要： The present invention relates to the field of communications, and disclosed are a method and device for determining a PDSCH transmission resource. 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.
