Abstract

A method and an apparatus are provided for transmitting and receiving uplink data in a wireless communication system. A method includes transmitting information on hopping; determining whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled; identifying a resource for receiving the uplink data based on the determination as to whether the mirroring is applied or not; and receiving the uplink data using the identified resource.

Claims

1. A method for receiving uplink data by a base station in a wireless communication system, the method comprising:

transmitting information on hopping;

determining whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled;

identifying a resource for receiving the uplink data based on the determination as to whether the mirroring is applied or not; and

receiving the uplink data using the identified resource.

2. The method of claim 1, further comprising transmitting hopping information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured via a higher layer signaling.

3. The method of claim 2, wherein the hopping information is cell-specific information.

4. The method of claim 1, wherein the information on hopping is included in uplink grant information.

5. A method for transmitting uplink data by a terminal in a wireless communication system, the method comprising:

receiving information on hopping;

determining whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled;

identifying a resource for transmitting the uplink data based on the determination as to whether the mirroring is applied or not; and

transmitting the uplink data using the identified resource.

6. The method of claim 5, further comprising receiving hopping information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured via a higher layer signaling.

7. The method of claim 6, wherein the hopping information is cell-specific information.

8. The method of claim 5, wherein the information on hopping is included in uplink grant information.

9. A base station for receiving uplink data in a wireless communication system, the base station comprising:

a transceiver configured to transmit and receive signals to and from a terminal; and

a controller configured to control the transceiver to transmit information on hopping, to determine whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled, to identify a resource for receiving the uplink data based on the determination as to whether the mirroring is applied or not, and to control the transceiver to receive the uplink data using the identified resource.

10. The base station of claim 9, wherein the controller is further configured to transmit hopping information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured via a higher layer signaling.

11. The base station of claim 10, wherein the hopping information is cell-specific information.

12. The base station of claim 9, wherein the information on hopping is included in uplink grant information.

13. A terminal for transmitting uplink data in a wireless communication system, the terminal comprising:

a transceiver configured to transmit and receive signals to and from a base station; and

a controller configured to control the transceiver to receive information on hopping, to determine whether mirroring is applied or not based on a packet transmission number, if the information on hopping indicates that a predefined hopping pattern is enabled, to identify a resource for transmitting the uplink data based on the determination as to whether the mirroring is applied or not, and to control the transceiver to transmit the uplink data using the identified resource.

14. The terminal of claim 13, wherein the controller is further configured to receive hopping information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured via a higher layer signaling.

15. The terminal of claim 14, wherein the hopping information is cell-specific information.

16. The terminal of claim 13, wherein the information on hopping is included in uplink grant information.
