Abstract:
1. A method for detecting an enhanced physical downlink control channel (EPDCCH) in a user equipment (UE), the method comprising the steps of: determining a location of a first enhanced control channel element (ECCE) occupied by at least one of a first candidate EPDCCH in a common search space using predetermined first parameters; detecting the first candidate EPDCCH occupied in the common search space based on the determined location of the first ECCE; determining a location of a second ECCE occupied by at least one of a second candidate EPDCCH in a specific search space using predetermined second parameters; and detecting the second candidate EPDCCH occupied in the specific search space based on the determined location of the second ECCE, wherein the common search space and the specific search space comprise a plurality of ECCEs, and the plurality of ECCEs comprised in the common search space and the specific search space is defined by a time resource and a frequency resource in a sub-frame for transmission of the EPDCCH.
