• the ePDCCH candidate carrying the downlink control information with the aggregation level of 16 occupies four groups of 16 resources, and each group includes four resources, and each group of resources is determined according to the method for determining the antenna port corresponding to the ePDCCH candidate with the aggregation level of 4, respectively. Antenna port.
• FIG. 6 is a diagram showing a mapping relationship between resources of another ePDCCH candidate and an antenna port according to an application example of the present invention
• mapping relationship is The mapping relationship between the antenna port corresponding to the ePDCCH candidate and the antenna port corresponding to the ePDCCH candidate carrying the downlink control information, and the mapping relationship between the antenna port corresponding to one or more ePDCCH candidates and other ePDCCH candidates.
• the mapping relationship between the corresponding antenna ports are caused by the difference between the sending and receiving roles, which are essentially the same.
• the following example is described by taking an example in which resources are composed of eCCEs. When resources are composed of eREGs, they are referred to.
