Abstract
A method for transmitting and receiving a signal by a terminal in a wireless communication system is disclosed in the present invention. More particularly, the method comprises the steps of: receiving an indicator for changing the usage of a specific subframe corresponding to a sub-component carrier from a network; determining whether near-end crosstalk between the sub-component carrier and another component carrier occurs if the usage of the subframe is changed according to the indicator; and transmitting and receiving a signal to and from the network through the sub-component carrier according to the changed usage if it is determined that the near-end crosstalk does not occur.

2. A method for communicating with a base station at a user equipment (UE) in a Time Division Duplex (TDD) communication system, the method comprising:
configuring subframe configuration according to a first subframe configuration defining subframe usages for each of subframes included in one radio frame, wherein a first subframe included in one radio frame is set as an uplink subframe based on the first subframe configuration, and wherein a sounding reference signal (SRS) is allocated in the first subframe based on the first subframe configuration; and re-configuring the subframe configuration from the first subframe configuration to a second subframe configuration, wherein the first subframe included in one radio frame is changed to a downlink subframe from the uplink subframe based on the re-configured second subframe configuration, and wherein the allocated SRS in the first subframe is dropped and a position corresponding to the dropped SRS in the first subframe is used for downlink when the first subframe is changed to the downlink subframe from the uplink subframe.
3. The method of claim 2, wherein information on the first subframe configuration is received via a system information message from the base station.
4. The method of claim 2, wherein the number of downlink subframes indicated by the second subframe configuration are greater than a number of downlink subframes indicated by the first subframe configuration.
5. The method of claim 2, wherein the subframe usages comprise the downlink subframe, the uplink subframe and a special subframe.
6. The method of claim 2,
wherein the uplink subframe and the changed downlink subframe are included in a secondary serving cell.
7. The method of claim 6,
wherein a physical downlink shared channel in the downlink subframe of the secondary serving cell is scheduled in a primary serving cell.
8. A user equipment (UE) in a Time Division Duplex (TDD) communication system, the user equipment comprising:
a radio frequency module for transmitting and receiving signals with a base station; and a processor for processing the signals, wherein the processor is configured to: set subframe configuration according to a first subframe configuration defining subframe usages for each of subframes included in one radio frame, wherein a first subframe included in one radio frame is set as an uplink subframe based on the first subframe configuration, and wherein a sounding reference signal (SRS) is allocated in the first subframe based on the first subframe configuration, and re-set the subframe configuration from the first subframe configuration to a second subframe configuration, wherein the first subframe included in one radio frame is changed to a downlink subframe from the uplink subframe based on the re-set second subframe configuration, and wherein the allocated SRS in the first subframe is dropped and a position corresponding to the dropped SRS in the first subframe is used for downlink when the first subframe is changed to the downlink subframe from the uplink subframe.
9. The UE of claim 8, wherein information on the first subframe configuration is received via a system information message from the base station.
10. The UE of claim 8, wherein the number of downlink subframes indicated by the second subframe configuration are greater than a number of downlink subframes indicated by the first subframe configuration.
11. The UE of claim 8, wherein the subframe usages comprise the downlink subframe, the uplink subframe and a special subframe.
12. The UE of claim 8,
wherein the uplink subframe and the changed downlink subframe are included in a secondary serving cell.
13. The UE of claim 12,
wherein a physical downlink shared channel in the downlink subframe of the secondary serving cell is scheduled in a primary serving cell.
