Abstract  Abstract

The invention relates to a wireless communication system. More particularly the present invention relates to a wireless communication system based on TDD receiving method for downlink control signal and to a device used in the method. said method comprises that in the special sub-frame comprises a downlink interval a guard interval and an uplink interval via the downlink interval step of receiving the downlink signal. a downlink interval guard combination of interval and an uplink interval usage related to the specific subframe configuration information is given. when the downlink interval such that the length is greater than a specific value mode gives configuration information in the special sub-frame to perform PDCCH detection step of the first type. when the downlink interval so that the length is equal to or less than a certain value given configuration information in the special sub-frame skipping detecting PDCCH of the first type. the PDCCH of the first type represents the subframe in the resource region of N OFDM symbols after set in the PDCCH wherein N is an integer of 2 or more.

The present invention relates to a wireless communication system. More particularly the present invention relates to a method for receiving a downlink control signal in a TDD-based wireless communication system and to an apparatus for the method. The method comprises a step of 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 a step for 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 a step for detecting the first type of PDCCH is skipped in the specific subframe. The first type of PDCCH represents the PDCCH which is set in a resource region following the Nth OFDM symbol in the subframe wherein N is an integer of 2 or more.
