Method and device for transmitting/obtaining control information in wireless communication system

摘要

An embodiment of the present invention relates to a method of obtaining control information through an enhanced physical downlink control channel (E-PDCCH) by a terminal in a wireless communication system. The method includes performing blind decoding on a common searching space in a set of first resource blocks on a subframe; and performing blind decoding on a terminal-specific searching space in a set of second resource blocks on the subframe, wherein a first start orthogonal frequency division multiplexing (OFDM) symbol of an E-PDCCH resource region including the common searching space in the set of first resource blocks and a second start OFDM symbol of an E-PDCCH resource region including the terminal-specific searching space in the set of second resource blocks are set individually.

1. A method for acquiring control information via an Enhanced Physical Downlink Control Channel (EPDCCH) at a User Equipment (UE) in a wireless communication system, the method comprising:
determining an index of a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of an EPDCCH in a subframe; and attempting to perform decoding on a UE-specific search space of the EPDCCH, wherein if the subframe is a subframe 1 or a subframe 6 for Time Division Duplexing (TDD), the index of the starting OFDM symbol is a smaller value between 2 and a higher-layer parameter which indicates the index of the starting OFDM symbol of the EPDCCH.
