Abstract

Methods and apparatuses are provided for transmitting data. An index of a first resource block is obtained from a scheduling grant. A user equipment determines a value related to hopping based on a sequence generated by cell specific information. The user equipment determines a value related to mirroring based on the sequence generated by the cell specific information. The user equipment determines a second resource block for uplink transmission by the index of the first resource block, the value related to hopping, and the value related to mirroring.

First claim

What is claimed is:

1. A method for transmitting data, the method comprising the steps of:
obtaining, by a user equipment, an index of a first resource block from a scheduling grant;
determining, by the user equipment, a value related to hopping based on a sequence generated by cell information;
determining, by the user equipment, a value related to mirroring based on the sequence generated by the cell information; and
determining, by the user equipment, a second resource block for uplink transmission by the index of the first resource block, the value related to hopping, and the value related to mirroring.

2. The method of claim 1 , wherein the value related to hopping and the value related to mirroring are determined in a subframe, if inter-subframe hopping is set.

3. The method of claim 2 , wherein the subframe is for one hybrid automatic repeat request (HARQ) process.

4. The method of claim 1 , wherein the value related to hopping and the value related to mirroring are determined in a slot, if intra-subframe and inter-subframe hopping are set.

5. The method of claim 1 , wherein a number of resource blocks in one subband is determined by a number of subbands.

6. The method of claim 1 , wherein the second resource block for uplink transmission is determined based on a summation of the index of the first resource block and a value derived by multiplying the value related to hopping and a number of resource blocks in one subband.

7. An apparatus for transmitting data, the apparatus comprising:
a receiver configured to receive a scheduling grant; and
a controller configured to obtain the index of the first resource block from the scheduling grant, determine a value related to hopping based on a sequence generated by cell information, determine a value related to mirroring based on the sequence generated by the cell information, and determine a second resource block for uplink transmission by the index of the first resource block, the value related to hopping, and the value related to mirroring.

8. The apparatus of claim 7 , wherein the value related to hopping and the value related to mirroring are determined in a subframe, if inter-subframe hopping is set.

9. The apparatus of claim 8 , wherein the subframe is for one hybrid automatic repeat request (HARQ) process.

10. The apparatus of claim 7 , wherein the value related to hopping and the value related to mirroring are determined in a slot, if intra-subframe and inter-subframe hopping are set.

11. The apparatus of claim 7 , wherein a number of resource blocks in one subband is determined by a number of subbands.

12. The apparatus of claim 7 , wherein the second resource block for uplink transmission is determined based on a summation of the index of the first resource block and a value derived by multiplying the value related to hopping and a number of resource blocks in one subband.

13. A method for receiving data, the method comprising the steps of:
transmitting a scheduling grant;
determining a value related to hopping based on a sequence generated by cell information;
determining a value related to mirroring based on the sequence generated by the cell information; and
determining a second resource block for uplink transmission by an index of a first resource block obtained from the scheduling grant, the value related to hopping, and the value related to mirroring.

14. The method of claim 13 , wherein the value related to hopping and the value related to mirroring are determined in a subframe, if inter-subframe hopping is set.

15. The method of claim 14 , wherein the subframe is for one hybrid automatic repeat request (HARQ) process.

16. The method of claim 13 , wherein the value related to hopping and the value related to mirroring are determined in a slot, if intra-subframe and inter-subframe hopping are set.

17. The method of claim 13 , wherein a number of resource blocks in one subband is determined by a number of subbands.

18. The method of claim 13 , wherein the second resource block for uplink transmission is determined based on a summation of the index of the first resource block and a value derived by multiplying the value related to hopping and a number of resource blocks in one subband.

19. An apparatus for transmitting data, the apparatus comprising:
a transmitter configured to transmit a scheduling grant; and
a controller configured to determine a value related to hopping based on a sequence generated by cell information, determine a value related to mirroring based on the sequence generated by the cell information, and determine a second resource block for uplink transmission by an index of a first resource block obtained from the scheduling grant, the value related to hopping, and the value related to mirroring.

20. The apparatus of claim 19 , wherein the value related to hopping and the value related to mirroring are determined in a subframe, if inter-subframe hopping is set.

21. The apparatus of claim 20 , wherein the subframe is for one hybrid automatic repeat request (HARQ) process.

22. The apparatus of claim 19 , wherein the value related to hopping and the value related to mirroring are determined in a slot, if intra-subframe and inter-subframe hopping are set.

23. The apparatus of claim 19 , wherein a number of resource blocks in one subband is determined by a number of subbands.

24. The apparatus of claim 19 , wherein the second resource block for uplink transmission is determined based on a summation of the index of the first resource block and a value derived by multiplying the value related to hopping and a number of resource blocks in one subband.
