Method and apparatus for effectively providing TDD configuration information to user equipment and determining uplink transmission timing in mobile communication system supporting TDD

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• control the transceiver to receive, from a base station, a system information block message including information on a first time division duplex(TDD) uplink/downlink(UL/DL) configuration, receive, from the base station, a physical downlink control channel(PDCCH) including downlink control information, the downlink control information including information related to a second TDD UL/DL configuration, receive, from the base station, uplink scheduling information for the terminal and transmit, to the base station, data in a subframe based on the uplink scheduling information,
• wherein the data is not transmitted in a subframe which is changed from an uplink subframe determined based on the information on the first TDD UL/DL configuration to a downlink subframe determined based on the information related to the second TDD UL/DL configuration.

A method by a base station in a communication system, the method comprising:

• transmitting, to a terminal, a system information block message including information on a first time division duplex(TDD) uplink/downlink(UL/DL) configuration;
• transmitting, to the terminal, a physical downlink control channel(PDCCH) including downlink control information, the downlink control information including information related to a second TDD UL/DL configuration;
• transmitting, to the terminal, uplink scheduling information for the terminal;
• and
• receiving, from the terminal, data in a subframe based on the uplink scheduling information,
• wherein the data is not received in a subframe which is changed from an uplink subframe determined based on the information on the first TDD UL/DL configuration to a downlink subframe determined based on the information related to the second TDD UL/DL configuration.
