Abstract

A method and apparatus for setting Reverse Link CQI Reporting Modes in an access terminal is provided, comprising determining a value for CQIReportingMode received as a parameter in a transmitted message and setting the reverse link CQI reporting mode of the access terminal based on CQIReportingMode value. The CQIReportingMode value is indicative of a reporting mode selected from a plurality of reporting modes.

Claims

1. A method of setting Reverse Link Channel Quality Indicator (CQI) Reporting Modes, comprising:

determining a CQI Reporting Mode value; and

setting a reverse link CQI reporting mode of an access terminal based on the CQI Reporting Mode value that indicates a reverse link CQI reporting mode to implement selected from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode.

2. The method of claim 1, wherein:

determining the CQI Reporting Mode value comprises receiving, by the access terminal, the CQI Reporting Mode value from an access point.

3. The method of claim 1, wherein:

setting the reverse link CQI reporting mode comprises sending the CQI Reporting Mode value to the access terminal.

4. The method of claim 1, wherein:

the group further comprises at least a Single Input and Single Output (SISO) CQI Reporting Mode.

8. The method of claim 1, wherein:

the group further comprises at least a Single Input and Single Output (SISO) CQI Reporting Mode.

5. A non-transitory machine readable storage medium including instructions stored thereon, comprising:

a first set of instructions for determining a CQI Reporting Mode value; and

a second set of instructions for setting a reverse link CQI reporting mode of an access terminal based on the CQI Reporting Mode value that indicates a reverse link CQI reporting mode to implement selected from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode.

6. The machine readable storage medium of claim 5, wherein:

determining the CQI Reporting Mode value comprises receiving, by the access terminal, the CQI Reporting Mode value from an access point.

7. The method of claim 5, wherein:

setting the reverse link CQI reporting mode comprises sending the CQI Reporting Mode value to the access terminal.

9. An apparatus operable in a wireless communication system, comprising:

means for determining a CQI Reporting Mode value; and

means for setting a reverse link CQI reporting mode of an access terminal based on the CQI Reporting Mode value that indicates a reverse link CQI reporting mode to implement selected from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode.

10. The apparatus of claim 9, wherein:

determining the CQI Reporting Mode value comprises receiving, by the access terminal, the CQI Reporting Mode value from an access point.

11. The method of claim 9, wherein:

setting the reverse link CQI reporting mode comprises sending the CQI Reporting Mode value to the access terminal.

12. The method of claim 9, wherein:

the group further comprises at least a Single Input and Single Output (SISO) CQI Reporting Mode.

13. An apparatus operable in a wireless communication system, comprising:

one or more processors for determining a CQI Reporting Mode value, and setting a reverse link CQI reporting mode of an access terminal based on the CQI Reporting Mode value that indicates a reverse link CQI reporting mode to implement selected from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode.

14. The apparatus of claim 13, wherein:

determining the CQI Reporting Mode value comprises receiving the CQI Reporting Mode value from an access point.

15. The method of claim 13, wherein:

setting the reverse link CQI reporting mode comprises sending the CQI Reporting Mode value to the access terminal.

16. The method of claim 13, wherein:

the group further comprises at least a Single Input and Single Output (SISO) CQI Reporting Mode.
