Operating method according to changed tdd uplink-downlink configuration in wireless communication system, and apparatus therefor

A terminal operating method according to a time division duplex (TDD) uplink-downlink configuration in a wireless communication system comprises: a step for receiving, from a base station operating in a full duplex mode, information for indicating a changed TDD uplink-downlink configuration corresponding to a specific TDD uplink-downlink configuration to be used; a step for receiving, from the base station, information for indicate a channel state for a downlink subframe of the changed TDD uplink-downlink configuration to be measured; and a step for generating channel state information by measuring the channel state, and transmitting the generated channel state information from an uplink subframe of the changed TDD uplink-downlink configuration to the base station.
