Abstract

A frequency allocation method and apparatus using a mirroring-assisted frequency hopping pattern is provided for retransmission in a wireless communication system operating in a frequency hopping mode. A frequency mapping method for a wireless communication system operating in a frequency hopping mode includes determining whether or not mirroring is used in accordance with a number of packet transmissions; mapping a frequency resource for a packet transmission based on a result of the determination; and receiving a packet using the mapped frequency resource.

Claims

1. A method of transmitting data, the method comprising:

receiving first frequency hopping information from a base station;

receiving an uplink grant including second frequency hopping information from the base station;

determining whether or not to apply mirroring based on a number of packet transmissions, if the second frequency hopping information indicates that predefined hopping is enabled; and

transmitting the data via an identified resource, in response to the uplink grant.

2. The method of claim 1, wherein the mirroring is applied alternatively in accordance with the number of packet transmissions.

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

4. The method of claim 1, wherein the first frequency hopping information indicates intra-subframe frequency hopping or inter-subframe frequency hopping.

5. The method of claim 1, wherein the first frequency hopping information is broadcasted by the base station.

6. An apparatus for transmitting data, the apparatus comprising:

a transceiver configured to receive first frequency hopping information from a base station, to receive an uplink grant including second frequency hopping information from the base station, and to transmit the data via an identified resource, in response to the uplink grant; and

a controller configured to determine whether or not to apply mirroring based on a number of packet transmissions, if the second frequency hopping information indicates that predefined hopping is enabled.

7. The apparatus of claim 6, wherein the mirroring is applied alternatively in accordance with the number of packet transmissions.

8. The apparatus of claim 6, wherein the first frequency hopping information includes cell-specific information.

9. The apparatus of claim 6, wherein the first frequency hopping information indicates intra-subframe frequency hopping or inter-subframe frequency hopping.

10. The apparatus of claim 6, wherein the first frequency hopping information is broadcasted by the base station.
