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;

selecting, based on the determined CQI Reporting Mode value, a reverse link CQI reporting mode from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode; and

setting the reverse link CQI reporting mode of an access terminal to the selected reverse link 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 comprise 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.

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;

a second set of instructions for selecting, based on the determined CQI Reporting Mode value, a reverse link CQI reporting mode from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode; and

a third set of instructions for setting the reverse link CQI reporting mode of an access terminal to the selected reverse link 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 machine readable storage medium of claim 5, wherein:

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

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

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

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

means for determining a CQI Reporting Mode value;

means for selecting, based on the determined CQI Reporting Mode value, a reverse link CQI reporting mode from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode; and

means for setting the reverse link CQI reporting mode of an access terminal to the selected reverse link 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 apparatus of claim 9, wherein:

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

12. The apparatus 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, selecting a reverse link CQI reporting mode from a group comprising at least a Single Code Word CQI Reporting Mode and a Multiple Code Word CQI Reporting Mode, and setting the reverse link CQI reporting mode of an access terminal to the selected reverse link 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 apparatus of claim 13, wherein:

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

16. The apparatus of claim 13, wherein:

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