Abstract

A method and an apparatus are provided for transmitting and receiving uplink data in a wireless communication system. The method includes transmitting an uplink grant including resource allocation information and frequency hopping information; determining a resource for the uplink data based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled; and receiving the uplink data mapped on the determined resource. Mirroring is alternatively applied for determining the resource based on the packet transmission number.

Claims

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

transmitting an uplink grant including resource allocation information and frequency hopping information;

determining a resource for the uplink data based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled; and

receiving the uplink data mapped on the determined resource,

wherein mirroring is alternatively applied for determining the resource based on the packet transmission number.

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

3. The method of claim 2, wherein the mirroring is enabled, if the inter-subframe frequency hopping is configured.

4. The method of claim 2, wherein the information includes cell-specific information.

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

receiving an uplink grant including resource allocation information and frequency hopping information;

mapping the uplink data on a resource determined based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled; and

transmitting the uplink data on the determined resource,

wherein mirroring is alternatively applied for determining the resource based on the packet transmission number.

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

7. The method of claim 6, wherein the mirroring is enabled, if the inter-subframe frequency hopping is configured.

8. The method of claim 6, wherein the information includes cell-specific information.

9. An apparatus for receiving uplink data in a wireless communication system, the apparatus comprising:

a transceiver configured to transmit an uplink grant including resource allocation information and frequency hopping information, and receive the uplink data mapped on a resource; and

a controller configured to determine the resource for the uplink data based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled,

wherein mirroring is alternatively applied for determining the resource based on the packet transmission number.

10. The apparatus of claim 9, wherein the transceiver is further configured to transmit information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured.

11. The apparatus of claim 10, wherein the mirroring is enabled, if the inter-subframe frequency hopping is configured.

12. The apparatus of claim 10, wherein the information includes cell-specific information.

13. An apparatus for transmitting uplink data in a wireless communication system, the apparatus comprising:

a transceiver configured to receive an uplink grant including resource allocation information and frequency hopping information, and transmitting the uplink data on a resource; and

a controller configured to map the uplink data on the resource determined based on the resource allocation information and a packet transmission number, if the frequency hopping information indicates that a predefined hopping pattern is enabled,

wherein mirroring is alternatively applied for determining the resource based on the packet transmission number.

14. The apparatus of claim 13, wherein the transceiver is further configured to receive information indicating whether intra-subframe frequency hopping or inter-subframe frequency hopping is configured.

15. The apparatus of claim 14, wherein the mirroring is enabled, if the inter-subframe frequency hopping is configured.

16. The apparatus of claim 14, wherein the information includes cell-specific information.
