The present invention relates to the field of communications, and provides a method and a device for enhanced-physical downlink control channel (E-PDCCH) transmission and blind detection. The method is: a network side carrying out corresponding E-PDCCH transmission resource configuration for allocation of each sub-frame; and a terminal respectively adopting different modes to perform E-PDCCH blind detection in each frame, so that better link adaptation of the E-PDCCH transmission can be implemented. Therefore, the balance of E-PDCCH transmission in the sub-frames is ensured, the effect of E-PDCCH blind detection of the terminal is further improved, and the E-PDCCH demodulation performance is further promoted.
