Abstract
The present invention relates to a method by which a terminal receives a downlink signal through an enhanced physical downlink control channel (EPDCCH) in a wireless communication system. The method includes the steps of: receiving one or more EPDCCH physical resource block (PRB) sets; and blind decoding EPDCCH candidates for each set level from among the one or more EPDCCH PRB sets, wherein one or more of EPDCCH candidate indexes and EPDCCH PRB indexes are used for determining an antenna port related to the EPDCCH candidates.
Claims14
A method for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE), the method comprising:
- receiving one or more EPDCCH PRB (Physical Resource Block) sets;
- and
- performing blind decoding of an EPDCCH candidate for each aggregation level in the one or more EPDCCH PRB sets,
- wherein at least one of an EPDCCH candidate index and an EPDCCH PRB set index is used to determine an antenna port related to the EPDCCH candidate.
A user equipment (UE) device for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system, the UE device comprising:
- a receiver configured to receive signals;
- and
- a processor configured to process the signals,
- wherein the processor configures to control the receiver to receive one or more EPDCCH PRB (Physical Resource Block) sets, and configures to perform blind decoding of an EPDCCH candidate for each aggregation level in the one or more EPDCCH PRB sets, and
- wherein at least one of an EPDCCH candidate index and an EPDCCH PRB set index is used to determine an antenna port related to the EPDCCH candidate.
A method for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE), the method comprising:
- receiving one or more EPDCCH PRB (Physical Resource Block) sets;
- and
- performing blind decoding of an EPDCCH candidate for each aggregation level in the one or more EPDCCH PRB sets,
- wherein a lowest enhanced control channel element (ECCE) index of the EPDCCH candidate, a user equipment identifier (UE ID), and a number of ECCEs for each resource block are used to determine the antenna port related to the EPDCCH candidate.
