Abstract

A method and apparatus for processing a Multi-code word assignment is provided, comprising receiving a MCW-FLAB1, determining value of supplemental field in the MCW-FLAB1 received with a MACID of an access terminal from the SS MAC protocol with a supplemental field, determining whether a MCW-FLAB2 is received with MACID in a same PHY frame and processing the MCW-FLAB1 based upon whether the MCW-FLAB2 is received and the value of the supplemental field.

Claims

1. A method for processing a Multi-code word assignment in a wireless communication system, comprising:

receiving a Multi Code Word Forward Link Assignment Block 1 (MCW-FLAB1);

determining a value of a supplemental field in the MCW-FLAB 1 received with a Medium Access Control Identifier (MACID) of an access terminal from a Shared Signaling Medium Access Control (SS MAC) protocol supporting the supplemental field;

determining that a Multi Code Word Forward Link Assignment Block 2 (MCW-FLAB2) is received with the MACID in a same Physical layer (PHY) frame; and

processing the MCW-FLAB1 based upon the determining that the MCW-FLAB2 is received and the value of the supplemental field.

2. The method as claimed in claim 1, wherein, in response to not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

0’

, the processing comprises ignoring the MCW-FLAB1.

3. The method as claimed in claim 1, wherein, in response to receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

0’

, the processing comprises using the MCW-FLAB1 and the MCW-FLAB2.

4. The method as claimed in claim 1, wherein, in response to setting the supplemental field value to ‘

1’

, the processing comprises updating packet formats for layer 2 and above according to the MCW-FLAB2.

5. The method as claimed in claim 1, wherein, in response to an existing assignment of type MCWFLAB, not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame, and the supplemental field value being set to ‘

1’

, the processing comprises using the current packet format for layer 2 and above.

6. A non-transitory computer-readable medium including instructions stored thereon, wherein the instructions are executed by a processor, comprising:

a first set of instructions for receiving a Multi Code Word Forward Link Assignment Block 1 (MCW-FLAB1);

a second set of instructions for determining a value of a supplemental field in the MCW-FLAB1 received with a Medium Access Control Identifier (MACID) of an access terminal from a Shared Signaling Medium Access Control (SS MAC) protocol with the supplemental field;

a third set of instructions for determining whether a Multi Code Word Forward Link Assignment Block 2 (MCW-FLAB2) is received with the MACID in a same Physical layer (PHY) frame; and

a fourth set of instructions for processing the MCW-FLAB1 based upon whether the MCW-FLAB2 is received and the value of the supplemental field.

7. The non-transitory computer-readable medium as claimed in claim 6, further comprising a fifth set of instructions for ignoring the MCW-FLAB1 as a function of not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

0’

.

8. The non-transitory computer-readable medium as claimed in claim 6, further comprising a sixth set of instructions for using the MCW-FLAB1 and the MCW-FLAB2 as a function of receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

0’

.

9. The non-transitory computer-readable medium as claimed in claim 6, further comprising a sixth set of instructions for updating packet formats for layer 2 and above according to the MCW-FLAB2 as a function of the supplemental field value being set to ‘

1’

.

10. The non-transitory computer-readable medium as claimed in claim 6, further comprising a sixth set of instructions for using the current packet format for layer 2 and above, in response to there being an existing assignment of type MCWFLAB as a function of not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

1’

.

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

a processor configured to;

receive a Multi Code Word Forward Link Assignment Block 1 (MCW-FLAB1);

determine a value of a supplemental field in the MCW-FLAB1 received with a Machine Access Control Identifier (MACID) of an access terminal from a Shared Signaling Medium Access Control (SS MAC) protocol with the supplemental field;

determine whether a Multi Code Word Forward Link Assignment Block 2 (MCW-FLAB2) is received with the MACID in a same Physical layer (PHY) frame; and

process the MCW-FLAB1 based upon whether the MCW-FLAB2 is received and the value of the supplemental field.

12. The apparatus as claimed in claim 11, the processor further configured to ignore the MCW-FLAB1 in response to not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

1’

.

15. The apparatus as claimed in claim 11, the processor further configured to use the current packet format for layer 2 and above, when there is an existing assignment of type MCWFLAB in response to not receiving the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame and the supplemental field value being set to ‘

1’

.

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

a receiver configured to receive a multi code word forward link assignment block 1 (MCW-FLAB1) with a Machine Access Control Identifier (MACID) of an access terminal from a Shared Signaling Medium Access Control (SS MAC) protocol supporting a supplemental field;
