Method for transmitting and receiving downlink control channels in wireless communication systems, and apparatus for same
First Claim
1. A method for receiving, by a user equipment (UE), a downlink signal from an evolved Node B (eNB) in a wireless communication system, the method comprising:
- receiving an enhanced physical downlink control channel (EPDCCH) for the UE from the eNB;
determining at least one physical resource block (PRB) pair for reception of a physical downlink shared channel (PDSCH), among a plurality of PRB pairs in a resource block group (RBG) allocated to the UE,wherein the at least one PRB pair is determined according to a size of the RBG; and
receiving the PDSCH based on the EPDCCH through the determined at least one PRB pair.

Abstract
The present invention relates to a method for receiving a downlink signal by a terminal from a base station in a wireless communication system. In particular, the method includes the steps of: receiving an enhanced physical downlink control channel (EPDCCH) for the terminal from the base station; selecting a first EPDCCH physical resource block (PRB) pair or a second EPDCCH PRB pair on the basis of the effective size of a resource block group (RBG) allocated to the terminal and/or the system bandwidth; and receiving a physical downlink shared channel (PDSCH) on the basis of the EPDCCH form among the remaining PRB pairs excluding the selected EPDCCH PRB from among PRB pairs included in the RBG.

8. A user equipment (UE) in a wireless communication system, the UE comprising:
-
a radio communication module configured to transmit signals in an evolved Node B (eNB) and receive signals from the eNB; and a processor configured to; process the signals, when an enhanced physical downlink control channel (EPDDCH) for the UE is received from the eNB, the processor is configured to select one of a first EPDCCH determine at least one physical resource block (PRB) pair for reception of a physical downlink shared channel (PDSCH), among a plurality of PRB pairs in a resource block group (RBG) allocated to the UE, wherein the at least one PRB pair is determined according to a size of the RBG, and control the radio communication module to receive the PDSCH based on the EPDCCH through the determined at least one PRB pair. - View Dependent Claims (9, 10, 11, 12, 13, 14)
