Abstract

Provided is a method and apparatus for scheduling in a wireless communication system. In the method, if frame configuration information is transmitted, the frame configuration information sets each sub-frame within a frame to either a default sub-frame or a variable sub-frame and transmits scheduling information which schedules the configured variable sub-frame; and if a signal based on the scheduling information from the configured variable sub-frame is transceived, the default sub-frame becomes a sub-frame for which the transmission direction is fixed, and the configured sub-frame is used as an uplink sub-frame or a downlink sub-frame according to the scheduling information.

Claims

1. A method of configuring subframes in a wireless communication system, the method performed by a user equipment (UE) and comprising:

receiving frame configuration information from a base station;

configuring each of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the frame configuration information, wherein the special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS); and

communicating with the base station using the configured subframes,

wherein a subframe configured to the downlink subframe or the special subframe cannot be used as an uplink subframe, and

wherein a subframe configured to the uplink subframe can be used as a downlink subframe.

2. The method of claim 1, wherein the frame configuration information is received through a radio resource control (RRC) message.

3. The method of claim 1, wherein the frame configuration information indicates any one of uplink-downlink configurations included in the below table

4. The method of claim 1, wherein the subframe configured to the downlink subframe is used for transmitting a synchronous signal or a broadcast signal.

5. The method of claim 4, wherein if the frame consists of 10 subframes and is indexed from 0 to 9 in sequence, subframes configured to a special subframe in the frame comprise a subframe #1.

6. The method of claim 1, wherein if the frame consists of 10 subframes and is indexed from 0 to 9 in sequence, subframes configured to a downlink subframe in the frame comprise a subframe #0 and a subframe #5.

7. A user equipment (UE) comprising:

a radio frequency (RF) unit configured to transmit and receive a radio signal; and

a processor coupled to the RF unit,

wherein the processor is configured to;

receive frame configuration information from a base station,

configure each of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the frame configuration information, wherein the special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS), and

communicate with the base station using the configured subframes,

wherein a subframe configured to the downlink subframe or the special subframe cannot be used as an uplink subframe, and

wherein a subframe configured to the uplink subframe can be used as a downlink subframe.

8. The UE of claim 7, wherein the frame configuration information is received through a radio resource control (RRC) message.

9. The UE of claim 7, wherein the frame configuration information indicates any one of uplink-downlink configurations included in the below table:

10. The UE of claim 7, wherein the subframe configured to the downlink subframe is used for transmitting a synchronous signal or a broadcast signal.

11. The UE of claim 7, wherein if the frame consists of 10 subframes and is indexed from 0 to 9 in sequence, subframes configured to a downlink subframe in the frame comprise a subframe #0 and a subframe #5.

12. The UE of claim 11, wherein if the frame consists of 10 subframes and is indexed from 0 to 9 in sequence, subframes configured to a special subframe in the frame comprise a subframe #1.
