Apparatus for transmitting and receiving downlink control information in a wireless access system and method thereof

摘要

Disclosed are an apparatus for transmitting and receiving downlink control information in a TDD (time division duplex) wireless access system and method thereof. The present invention includes performing a blind decoding on a transmitting region of e-PDCCH (enhanced physical downlink control channel) transmitted by being multiplexed with PDSCH (physical downlink shared channel) and receiving the DCI through the blind decoding of the e-PDCCH. In particular, a last symbol of the transmitting region of the e-PDCCH in a special subframe is configured in accordance with a configuration of the special subframe.

1. A method of receiving DCI (downlink control information) in a TDD (time division duplex) wireless access system, comprising the steps of:
performing a blind decoding on a transmitting region of an e-PDCCH (enhanced physical downlink control channel) transmitted by being multiplexed with a PDSCH (physical downlink shared channel); and receiving the DCI through the blind decoding of the e-PDCCH, wherein a last symbol of the transmitting region of the e-PDCCH in a special subframe is configured in accordance with a configuration of the special subframe, and when the configuration of the special subframe is 1 to 4 and 6 to 8, the last symbol of the transmitting region of the e-PDCCH in the special subframe is configured as a last symbol in a first slot of the special subframe.
