Abstract:
1. A method of receiving a downlink control channel located in a data region, in user equipment (UE), the method comprising: receiving an enhanced physical downlink control channel (EPDCCH) from a transmission/reception point, wherein the EPDCCH includes a data region of an N number of physical resource-block (PRB) pairs forming each of a K number of EPDCCH sets in a subframe, and wherein (i) the K and N are natural numbers which are greater than or equal to “1”, (ii) each of the N number of PRB pairs includes decoding the EPDCCH in a corresponding EPDCCH set according to a downlink control information (DCI) format in an EPDCCH UE-specific search space, wherein ECCEs associated with the decoding of the EPDCCH are defined by a function of a radio network temporary identifier (RNTI) of the user equipment, an index of the subframe, an aggregation level, and a total number of ECCEs of the corresponding EPDCCH set.
