Retransmission method for dynamic subframe setting in wireless communication system and apparatus for same

摘要

Disclosed is a method for allowing a terminal to transmit and receive signals to and/from a base station in a wireless communication system using a time division multiplexing method. Specifically, the method comprises the steps of: receiving a request signal for resetting into a second uplink/downlink setting while transmitting and receiving a signal according to a first uplink/downlink setting; terminating an uplink retransmission process associated with a specific uplink subframe when the use of the specific uplink subframe is changed into a downlink subframe according to the second uplink/downlink setting; and applying the second uplink/downlink setting at a specific time point to transmit and receive signals.

1. A method for determining an Uplink-Downlink configuration by a user equipment in a wireless communication system, the method comprising:
receiving a TDD (Time Division Duplex) configuration related to a reconfiguration command transmission, wherein the TDD configuration includes a periodicity configuration and a subframe set configuration for reconfiguring TDD; setting uplink-downlink configuration based on the reconfiguration command, if the reconfiguration command is detected in a subframe indicated by the subframe set configuration, wherein the uplink-downlink configuration is configured to be applied from a first subframe of a radio frame, and if the reconfiguration command is received in subframe 0 of the radio frame, the uplink-downlink configuration being reconfigured from subframe 0 of the radio frame, and if the reconfiguration command is received in a subframe other than subframe 0 of the radio frame, the uplink-downlink configuration being reconfigured from subframe 0 of a next radio frame after the radio frame.
