Abstract

An approach is provided for efficient retransmissions by allocating a transmission resource for transmitting data and allocating a retransmission resource for retransmitting the data according to a transmission scheme that specifies relationship between the transmitted data and the retransmitted data for providing communication over a radio network.

Claims

1. A method comprising:

allocating a first transmission resource for transmitting data according to a transmission scheme; and

allocating a second transmission resource for retransmitting the data according to the transmission scheme, wherein the transmission scheme specifies a relationship between the transmitted data and the retransmitted data for error detection of the transmitted data.

2. A method according to claim 1, wherein the error detection is performed according to a hybrid automatic repeat request (HARQ) protocol.

3. A method according to claim 1, wherein the transmission scheme provides transmission of the data using an allocation fixed in frequency, and the retransmission of the data uses allocation in time to specify the relationship.

4. A method according to claim 1, wherein the transmission scheme provides transmission of the data using an allocation fixed in time, and the retransmission of the data uses allocation in frequency to specify the relationship.

5. A method according to claim 1, wherein the transmitted data is combined with the retransmitted data based on the specified relationship.

6. A method according to claim 1, wherein the channel quality information is transmitted to a base station of a Third Generation Partnership Project (3GPP) system.

7. An apparatus comprising:

a processor configured to allocate a first transmission resource for transmitting data according to a transmission scheme, and to allocate a second transmission resource for retransmitting the data according to the transmission scheme,

wherein the transmission scheme specifies a relationship between the transmitted data and the retransmitted data for error detection of the transmitted data.

8. An apparatus according to claim 7, wherein the error detection is performed according to a hybrid automatic repeat request (HARQ) protocol.

9. An apparatus according to claim 7, wherein the transmission scheme provides transmission of the data using an allocation fixed in frequency, and the retransmission of the data uses allocation in time to specify the relationship.

10. An apparatus according to claim 7, wherein the transmission scheme provides transmission of the data using an allocation fixed in time, and the retransmission of the data uses allocation in frequency to specify the relationship.

11. An apparatus according to claim 7, wherein the transmitted data is combined with the retransmitted data based on the specified relationship.

12. An apparatus according to claim 7, wherein the channel quality information is transmitted to a base station of a Third Generation Partnership Project (3GPP) system.

22. An apparatus according to claim 10, wherein the apparatus is a handset.

13. A system comprises:

a base station configured to allocate a first transmission resource for transmitting data according to a transmission scheme and to allocate a second transmission resource for retransmitting the data according to the transmission scheme,

wherein the transmission scheme specifies a relationship between the transmitted data and the retransmitted data for error detection of the transmitted data.

14. An apparatus comprises:

means for allocating a first transmission resource for transmitting data according to a transmission scheme; and

means for allocating a second transmission resource for retransmitting the data according to the transmission scheme,

wherein the transmission scheme specifies a relationship between the transmitted data and the retransmitted data for error detection of the transmitted data.

15. A method comprises:

receiving data according to a first allocation;

receiving retransmission of the data according to a second allocation that specifies a relationship with the received data; and

combining the received data and the retransmitted data based on the relationship.

16. A method according to claim 15, further comprising:

determining whether the received data has an error, and sending an acknowledgement message based on the determination.

17. A method according to claim 16, wherein the determining step is performed according to a hybrid automatic repeat request (HARQ) protocol.

18. A method according to claim 15, wherein the first allocation is fixed in frequency, and the second allocation is based on time to specify the relationship.

19. A method according to claim 15, wherein the first allocation is fixed in time, and the second allocation is based on frequency to specify the relationship.

20. A method according to claim 15, wherein the channel quality information is transmitted to a base station of a Third Generation Partnership Project (3GPP) system.

21. An apparatus comprising:

a transceiver configured to receive data according to a first allocation, and to receive retransmission of the data according to a second allocation that specifies a relationship with the received data; and

error detection logic configured to combine the received data and the retransmitted data based on the relationship.
