Method and apparatus for transmitting control information in wireless communication system

摘要

The present invention relates to a method for receiving a downlink control signal in a TDD-based wireless communication system, and to an apparatus therefor. The method comprises receiving a downlink signal via a downlink interval in a specific frame including the downlink interval, a guard interval and an uplink interval. A combination of the downlink interval, the guard interval and the uplink interval is given using configuration information on the specific subframe. When the configuration information is given such that the length of the downlink interval is larger than a specific value, detecting a first type of PDCCH is performed in the specific subframe. When the configuration information is given such that the length of the downlink interval is equal to or smaller than the specific value, detecting the first type of PDCCH is skipped in the specific subframe.

1. A method for receiving a downlink control signal by a user equipment in a time division duplex (TDD)-based wireless communication system, the method comprising:
receiving the downlink control signal in a special subframe including a downlink period, a guard period, and an uplink period, wherein lengths of the downlink period, the guard period, and the uplink period are defined according to configuration information for the special subframe; performing a detection process in the special subframe for a physical downlink control channel (PDCCH) of a 1st type when the configuration information is such that the length of the downlink period is greater than a specific value; and skipping the detection process for the PDCCH of the 1st type when the configuration information is such that the length of the downlink period is equal to or less than the specific value, wherein the PDCCH of the 1st type indicates a PDCCH configured within a resource region starting from an Nth orthogonal frequency-division multiplexing (OFDM) symbol in a subframe, and wherein N is an integer of 2 or more.
