1. A method by a terminal, the method comprising:receiving system information including a first time division duplex (TDD) configuration, wherein the first TDD configuration is one of a predetermined set of TDD configurations;
receiving configuration information including information associated with a first subframe, via a higher layer signaling;
receiving, on a physical downlink control channel (PDCCH), control information in the first subframe identified based on the configuration information; and
identifying a second TDD configuration, wherein the second TDD configuration is one of a subset of the predetermined set of TDD configurations based on the control information,
wherein the first TDD configuration and the second TDD configuration are associated with a type of each subframe in a radio frame.
