Dynamic TDD data channel transmission method and apparatus for wireless communication system

A method by a base station, the method comprising:

• transmitting system information including a first time division duplex (TDD) configuration, wherein the first TDD configuration is one of a predetermined set of TDD configurations;
• transmitting configuration information including information associated with a first subframe, via a higher layer signaling;
• transmitting, on a physical downlink control channel (PDCCH), control information in the first subframe identified based on the configuration information,
• wherein the control information is used to identify a second TDD configuration, wherein the second TDD configuration is one of a subset of the predetermined set of TDD configurations, and
• wherein the first TDD configuration and the second TDD configuration are associated with a type of each subframe in a radio frame.

A terminal, comprising:

• a transceiver;
• and
• a controller configured to:
• receive system information including a first time division duplex (TDD) configuration, wherein the first TDD configuration is one of a predetermined set of TDD configurations,
• receive configuration information including information associated with a first subframe, via a higher layer signaling,
• receive, on a physical downlink control channel (PDCCH), control information in the first subframe identified based on the configuration information, and
• identify 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.
