Abstract

A method and apparatus are provided for transmitting a Reference Signal (RS) by a User Equipment (UE) in a wireless communication system. The method includes transmitting a DeModulation Reference Signal (DM RS) and information data in a sub-frame; and transmitting a Sounding Reference Signal (SRS) in a last symbol in another sub-frame. The DM RS is transmitted in a middle symbol in each slot of the sub-frame, and the information data is transmitted in other symbols in each slot of the sub-frame.

Claims (66)

1. A method for transmitting a reference signal (RS) by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting a demodulation reference signal (DM RS) and information data in a sub-frame; and

transmitting a sounding reference signal (SRS) in a last symbol in a second slot from among two slots included in another sub-frame,

wherein the DM RS is transmitted in only a middle symbol in each slot of the sub-frame, and

wherein the information data is transmitted in other symbols in each slot of the sub-frame.

2. The method of claim 1 , wherein a cyclic shift value used for transmitting the DM RS is different from a cyclic shift value used for transmitting the SRS.

3. The method of claim 1 , wherein the DM RS and the information data are transmitted over a same bandwidth.

4. The method of claim 1 , wherein a bandwidth used for transmitting the DM RS is different from a bandwidth used for transmitting the SRS.

5. A method for receiving a reference signal (RS) by a node B in a wireless communication system, the method comprising:

receiving a demodulation reference signal (DM RS) and information data in a sub-frame; and

receiving a sounding reference signal (SRS) in a last symbol in a second slot from among two slots included in another sub-frame,

wherein the DM RS is received in only a middle symbol in each slot of the sub-frame, and

wherein the information data is received in other symbols in each slot of the sub-frame.

6. The method of claim 5 , wherein a cyclic shift value used for receiving the DM RS is different from a cyclic shift value used for receiving the SRS.

7. The method of claim 5 , wherein the DM RS and the information data are received over a same bandwidth.

8. The method of claim 5 , wherein a bandwidth used for receiving the DM RS is different from a bandwidth used for receiving the SRS.

9. A user equipment (UE) for transmitting a reference signal (RS) in a wireless communication system, the UE comprising:

a controller; and

a transmitter configured to transmit a demodulation reference signal (DM RS) and information data in a sub-frame, and to transmit a sounding reference signal (SRS) in a last symbol in a second slot from among two slots included in another sub-frame,

wherein the DM RS is transmitted in only a middle symbol in each slot of the sub-frame, and

wherein the information data is transmitted in other symbols in each slot of the sub-frame.

10. The UE of claim 9 , wherein a cyclic shift value used for transmitting the DM RS is different from a cyclic shift value used for transmitting the SRS.

11. The UE of claim 9 , wherein the DM RS and the information data are transmitted over a same bandwidth.

12. The UE of claim 9 , wherein a bandwidth used for transmitting the DM RS is different from a bandwidth used for transmitting the SRS.

13. A node B for receiving a reference signal (RS) in a wireless communication system, the node B comprising:

a controller; and

a receiver configured to receive a demodulation reference signal (DM RS) and information data in a sub-frame, and to receive a sounding reference signal (SRS) in a last symbol in a second slot from among two slots included in another sub-frame,

wherein the DM RS is received in only a middle symbol in each slot of the sub-frame, and

wherein the information data is received in other symbols in each slot of the sub-frame.

14. The node B of claim 13 , wherein a cyclic shift value used for receiving the DM RS is different from a cyclic shift value used for receiving the SRS.

15. The node B of claim 13 , wherein the DM RS and the information data are received over a same bandwidth.

16. The node B of claim 13 , wherein a bandwidth used for receiving the DM RS is different from a bandwidth used for receiving the SRS.

17. A method for transmitting a reference signal (RS) by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting a demodulation reference signal (DM RS), information data, and a sounding reference signal (SRS) in a sub-frame including two slots, each of the two slot including seven symbols,

wherein the DM RS is transmitted in a middle symbol in each of the two slots,

wherein the SRS is transmitted in a last symbol in a second slot from among the two slots, and

wherein the information data is transmitted in first, second, third, fifth, sixth, and seventh symbols in a first slot from among the two slots, and in first, second, third, fifth, and sixth symbols in the second slot.

18. The method of claim 17 , wherein a cyclic shift value used for transmitting the DM RS is different from a cyclic shift value used for transmitting the SRS.

19. The method of claim 17 , wherein the DM RS and the information data are transmitted over a same bandwidth.

20. The method of claim 17 , wherein a bandwidth used for transmitting the DM RS is different from a bandwidth used for transmitting the SRS.

21. A method for receiving a reference signal (RS) by a node B in a wireless communication system, the method comprising:

receiving a demodulation reference signal (DM RS), information data, and a sounding reference signal (SRS) in a sub-frame including two slots, each of the two slots including seven symbols,

22. The method of claim 21 , wherein a cyclic shift value used for receiving the DM RS is different from a cyclic shift values used for receiving the SRS.

23. The method of claim 21 , wherein the DM RS and the information data are received over a same bandwidth.

24. The method of claim 21 , wherein a bandwidth used for receiving the DM RS is different from a bandwidth used for receiving the SRS.

25. A user equipment (UE) for transmitting a reference signal (RS) in a wireless communication system, the UE comprising:

a controller; and
