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 signal by a user equipment in a Time Division Duplex (TDD)-based wireless communication system, the method comprising:
receiving a downlink control signal via a downlink period in a specific subframe comprising the downlink period, a guard period, and an uplink period, wherein each length of the downlink period, the guard period, and the uplink period is given according to configuration information for the specific subframe, wherein when the configuration information corresponds to a first value, a detection process for a first-type physical downlink control channel (PDCCH) is performed in the specific subframe, wherein when the configuration information corresponds to a second value other than the first value, the detection process for the first-type PDCCH is skipped in the specific subframe, wherein the first-type PDCCH indicates a PDCCH configured within a resource region from a specific orthogonal frequency division multiplexing (OFDM) symbol other than a starting OFDM symbol in a subframe.
