Disclosed are a method for determining and indicating a transmission resource, and a terminal and a base station. The method comprises: a base station and a UE agreeing that at least one subframe of a set number of wireless frames is used as a reference subframe, and considering that all REs in the reference subframe which are probably occupied by a ZP/NZP CSI-RS are REs unable to be used for EPDCCH transmission; and the base station sending to a UE configuration information about REs in other subframes which are occupied by the ZP/NZP CSI-RS in the reference subframe, so that the UE can determine REs in other subframes, which are probably occupied by the ZP/NZP CSI-RS but are in fact not occupied by the ZP/NZP CSI-RS as REs used for the EPDCCH transmission, thereby increasing the number of REs used for EPDCCH transmission, and reducing the system overheads.
