USER EQUIPMENTS, BASE STATIONS AND METHODS

摘要

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.
