1. A user equipment (UE) comprising:
- a higher layer processor configured to receive an RRC message for enhanced resource element group (EREG) configuration; and
a physical downlink control channel receiver configured to monitor an enhanced physical downlink control channel (EPDCCH) on the basis of a first EREG structure if the EREG configuration is not established, and to monitor the EPDCCH on the basis of a second EREG structure if the EREG configuration is established;
wherein all resource elements (REs) with number i in a physical resource block (PRB) pair comprise EREG number i, wherein i is an integer number, and whereinin the first EREG structure, the EREG number i is based on numbering all resource elements, except for resource elements carrying demodulation reference signal (DM-RS), in the PRB pair cyclically from an index set in an increasing order of first frequency and then time, andin the second EREG structure, the EREG number i is based on numbering all resource elements, except for resource elements carrying demodulation reference signal (DM-RS), on a set of consecutive OFDM symbols within the PRB pair cyclically from a subset of the index set in an increasing order of first frequency and then time.

Abstract
A user equipment (UE) is described. The UE includes a higher layer processor configured to receive an RRC message for enhanced resource element group (EREG) configuration. The UE also includes a physical downlink control channel receiver configured to monitor an enhanced physical downlink control channel (EPDCCH) on the basis of a first EREG structure if the EREG configuration is not established, and to monitor the EPDCCH on the basis of a second EREG structure if the EREG configuration is established. All resource elements (REs) with number i in a physical resource block (PRB) pair comprise EREG number i.

5. An evolved NodeB (eNB), comprising:
-
a higher layer processor configured to send an RRC message for enhanced resource element group (EREG) configuration; and a physical downlink control channel transmitter configured to transmit an enhanced physical downlink control channel (EPDCCH) on the basis of a first EREG structure if the EREG configuration is not established, and to transmit the EPDCCH on the basis of a second EREG structure if the EREG configuration is established; wherein all resource elements (REs) with number i in a physical resource block pair (PRB pair) comprise EREG number i, wherein i is an integer number, and wherein in the first EREG structure, the EREG number i is based on numbering all resource elements, except for resource elements carrying demodulation reference signal (DM-RS), in the PRB pair cyclically from an index set in an increasing order of first frequency and then time, and in the second EREG structure, the EREG number i is based on numbering all resource elements, except for resource elements carrying demodulation reference signal (DM-RS), on a set of consecutive OFDM symbols within the PRB pair cyclically from a subset of the index set in an increasing order of first frequency, then time. - View Dependent Claims (6, 7, 8)
