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 in an access terminal in a wireless communication system, comprising:

a processor-implemented act of executing processor executable instructions stored on a machine readable storage medium to implement the following;

determining a value for CQIReportingMode; and

setting a reverse link CQI reporting mode of the access terminal based on CQIReportingMode value that indicates a reverse link CQI reporting mode to implement selected from a group consisting of a Single Code Word CQI Reporting Mode, a Multiple Code Word CQI Reporting Mode, and a Single Input and Single Output (SISO) CQI Reporting Mode, wherein;

the reverse link CQI reporting mode of the access terminal is set to be Single Code Word CQI Reporting Mode if the CQIReportingMode value indicates Single Code Word CQI Reporting Mode;

the reverse link CQI reporting mode of the access terminal is set to be Multiple Code Word CQI Reporting Mode if the CQIReportingMode value indicates Multiple Code Word CQI Reporting Mode; and

the reverse link CQI reporting mode of the access terminal is set to be Single Input and Single Output (SISO) CQI Reporting Mode if the CQIReportingMode value indicates Single Input and Single Output (SISO) Reporting Mode.

2. A non-transitory machine readable storage medium including instruction stored thereon, comprising:

a first set of instructions for determining a value for CQIReportingMode; and

a second set of instructions for setting a reverse link CQI reporting mode of the access terminal based on CQIReportingMode value that indicates a reverse link CQI reporting mode to implement selected from a group consisting of a Single Code Word CQI Reporting Mode, a Multiple Code Word CQI Reporting Mode, and a Single Input and Single Output (SISO) CQI Reporting Mode, wherein;

the reverse link CQI reporting mode of the access terminal is set to be Single Code Word CQI Reporting Mode if the CQIReportingMode value indicates Single Code Word CQI Reporting Mode;

the reverse link CQI reporting mode of the access terminal is set to be Multiple Code Word CQI Reporting Mode if the CQIReportingMode value indicates Multiple Code Word CQI Reporting Mode; and

the reverse link CQI reporting mode of the access terminal is set to be Single Input and Single Output (SISO) CQI Reporting Mode if the CQIReportingMode value indicates Single Input and Single Output (SISO) Reporting Mode.

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

means for determining a value for CQIReportingMode; and

means for setting a reverse link CQI reporting mode of the access terminal based on CQIReportingMode value that indicates a reverse link CQI reporting mode to implement selected from a group consisting of a Single Code Word CQI Reporting Mode, a Multiple Code Word CQI Reporting Mode, and a Single Input and Single Output (SISO) CQI Reporting Mode, wherein;

the reverse link CQI reporting mode of the access terminal is set to be Single Code Word CQI Reporting Mode if the CQIReportingMode value indicates Single Code Word CQI Reporting Mode;

the reverse link CQI reporting mode of the access terminal is set to be Multiple Code Word CQI Reporting Mode if the CQIReportingMode value indicates Multiple Code Word CQI Reporting Mode; and

the reverse link CQI reporting mode of the access terminal is set to be Single Input and Single Output (SISO) CQI Reporting Mode if the CQIReportingMode value indicates Single Input and Single Output (SISO) Reporting Mode.

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

one or more processors determining a value for CQIReportingMode, the one or more processors setting a reverse link CQI reporting mode of the access terminal based on CQIReportingMode value that indicates a reverse link CQI reporting mode to implement selected from a group consisting of a Single Code Word CQI Reporting Mode, a Multiple Code Word CQI Reporting Mode, and a Single Input and Single Output (SISO) CQI Reporting Mode, wherein;

the reverse link CQI reporting mode of the access terminal is set to be Single Code Word CQI Reporting Mode if the CQIReportingMode value indicates Single Code Word CQI Reporting Mode;

the reverse link CQI reporting mode of the access terminal is set to be Multiple Code Word CQI Reporting Mode if the CQIReportingMode value indicates Multiple Code Word CQI Reporting Mode; and

the reverse link CQI reporting mode of the access terminal is set to be Single Input and Single Output (SISO) CQI Reporting Mode if the CQIReportingMode value indicates Single Input and Single Output (SISO) Reporting Mode.
