Abstract
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.
Claims6
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.
A user equipment, which receives DCI (downlink control information) in a TDD (time division duplex) wireless access system, comprising:
- an RF (radio frequency) unit configured to transmit and receive a radio signal;
- and
- a processor configured to control the RF unit, the processor further configured to perform 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 receive 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.
