Abstract

A mobile device may generate reference bits. The mobile device may also produce a frame to send in an uplink transmission having two portions selectively with the reference bits or data bits.

First claim

What is claimed is:

1. A method performed by a mobile device, the method comprising:
generating, by a processor of the mobile device, first reference blocks and second reference blocks;
producing, by the mobile device, a frame that includes a first part and a second part;
wherein the first part includes the first reference blocks and data blocks;
wherein every other block of the second part includes the second reference blocks and the second part does not include data blocks; and
transmitting, by the mobile device, the frame.

2. The method of claim 1 , wherein the first reference blocks and the second reference blocks are pilot symbols.

3. The method of claim 1 , wherein a predetermined number of data blocks are between reference blocks of the first part.

4. The method of claim 1 , wherein the reference blocks and non-reference blocks of the second part are time multiplexed.

5. The method of claim 1 , wherein at least one of the first reference blocks is derived from an orthogonal code.

6. The method of claim 1 , wherein the first reference blocks are derived from a first sequence and the second reference blocks are derived from a second sequence.

7. The method of claim 1 , wherein the frame is a Code Division Multiple Access (CDMA) frame.

8. A method performed by a network device, the method comprising:
receiving, by the network device, a frame from a mobile device, wherein the frame includes a first part and a second part;
wherein the first part includes first reference blocks and data blocks; and
wherein every other block of the second part includes second reference blocks and the second part does not include data blocks of the mobile device.

9. The method of claim 8 , wherein the first reference blocks and the second reference blocks are pilot symbols.

10. The method of claim 8 , wherein a predetermined number of data blocks are between reference blocks of the first part.

11. The method of claim 8 , wherein the reference blocks and non-reference blocks of the second part are time multiplexed.

12. The method of claim 8 , wherein at least one of the first reference blocks is derived from an orthogonal code.

13. The method of claim 8 , wherein the first reference blocks are derived from a first sequence and the second reference blocks are derived from a second sequence.

14. The method of claim 8 , wherein the frame is a Code Division Multiple Access (CDMA) frame.

15. A mobile device comprising:
a processor configured to generate first reference blocks and second reference blocks;
the processor configured to produce a frame that includes a first part and a second part;
wherein the first part includes the first reference blocks and data blocks;
wherein every other block of the second part includes the second reference blocks and the second part does not include data blocks;
and
a transmitter configured to transmit the frame.

16. The mobile device of claim 15 , wherein the first reference blocks and the second reference blocks are pilot symbols.

17. The mobile device of claim 15 , wherein a predetermined number of data blocks are between reference blocks of the first part.

18. The mobile device of claim 15 , wherein the reference blocks and non-reference blocks of the part are time multiplexed.

19. The mobile device of claim 15 , wherein at least one of the first reference blocks is derived from an orthogonal code.

20. The mobile device of claim 15 , wherein the first reference blocks are derived from a first sequence and the second reference blocks are derived from a second sequence.

21. The mobile device of claim 15 , wherein the frame is a Code Division Multiple Access (CDMA) frame.

22. A network device comprising:
circuitry configured to receive a frame from a mobile device, wherein the frame includes a first part and a second part;
wherein the first part includes first reference blocks and data blocks; and
wherein every other block of the second part includes second reference blocks and the second part does not include data blocks of the mobile device.

23. The network device of claim 22 , wherein the first reference blocks and the second reference blocks are pilot symbols.

24. The network device of claim 22 , wherein a predetermined number of data blocks are between reference blocks of the first part.

25. The network device of claim 22 , wherein the second reference blocks and non-reference blocks of the second part are time multiplexed.

26. The network device of claim 22 , wherein at least one of the first reference blocks is derived from an orthogonal code.

27. The network device of claim 22 , wherein the first reference blocks are derived from a first sequence and the second reference blocks are derived from a second sequence.

28. The network device of claim 22 , wherein the frame is a Code Division Multiple Access (CDMA) frame.
