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

摘要

A method for configuring a time division duplex (TDD) of a user equipment in a communication system, according to one embodiment of the present invention, comprises the steps of: receiving from a base station a first TDD configuration; receiving from the base station a message including information related to a dynamic TDD configuration; receiving a second TDD configuration according to the received information related to the dynamic TDD configuration; receiving from the base station an uplink grant; and determining whether to apply the first TDD configuration or the second TDD configuration based on a method by which the unlink grant is received. According to one embodiment of the present invention, the advantages of configuring a shorter cycle of the TDD to the user equipment supporting the TDD in a wireless communication system, and rapidly configuring the TDD to the user equipment variably according to a communication situation are provided.

1. A method of a terminal in a communication system, the method comprising:
receiving a first time division duplex (TDD) uplink/downlink (UL/DL) configuration from a base station; receiving configuration information related to a second TDD UL/DL configuration from the base station; receiving downlink control information indicating the second TDD configuration from the base station based on the received configuration information; transmitting, if uplink scheduling information is received in a random access response message, a message corresponding to the uplink scheduling information to the base station based on the first TDD UL/DL configuration; and transmitting, if uplink scheduling information is received on a physical downlink control channel (PDCCH), a message corresponding to the uplink scheduling information to the base station based on the second TDD UL/DL configuration.
