Abstract

A method and an apparatus are provided for transmitting and receiving uplink data in a wireless communication system. A method includes transmitting first information on hopping, the first information on hopping indicating that one of inter-subframe hopping and intra-subframe hopping is configured; transmitting second information on hopping; determining whether mirroring is applied or not based on a packet transmission number, if the second 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.

First claim

What is claimed is:

1. A method for receiving uplink data by a base station in a wireless communication system, the method comprising:
transmitting first information on hopping, the first information on hopping indicating that one of inter-subframe hopping and intra-subframe hopping is configured;
transmitting second information on hopping;
determining whether mirroring is applied or not based on a packet transmission number, if the second 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 , wherein the second information on hopping is included in uplink grant information.

3. The method of claim 1 , wherein the first information on hopping is cell-specific information.

4. A method for transmitting uplink data by a terminal in a wireless communication system, the method comprising:
receiving first information on hopping,
the first information on hopping indicating that one of inter-subframe hopping and intra-subframe hopping is configured;
receiving second information on hopping;
determining whether mirroring is applied or not based on a packet transmission number, if the second 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.

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

6. The method of claim 4 , wherein the first information on hopping is cell-specific information.

7. 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 first information on hopping, the first information on hopping indicating that one of inter-subframe hopping and intra-subframe hopping is configured,
control the transceiver to transmit second information on hopping,
determine whether mirroring is applied or not based on a packet transmission number, if the second information on hopping indicates that a predefined hopping pattern is enabled,
identify a resource for receiving the uplink data based on the determination as to whether the mirroring is applied or not, and
control the transceiver to receive the uplink data using the identified resource.

8. The base station of claim 7 , wherein the second information on hopping is included in uplink grant information.

9. The base station of claim 7 , wherein the first information on hopping is cell-specific information.

10. 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 first information on hopping, the first information on hopping indicating that one of inter-subframe hopping and intra-subframe hopping is configured,
control the transceiver to receive second information on hopping,
determine whether mirroring is applied or not based on a packet transmission number, if the second information on hopping indicates that a predefined hopping pattern is enabled,
identify a resource for transmitting the uplink data based on the determination as to whether the mirroring is applied or not, and
control the transceiver to transmit the uplink data using the identified resource.

11. The terminal of claim 10 , wherein the second information on hopping is included in uplink grant information.

12. The terminal of claim 10 , wherein the first information on hopping is cell-specific information.
