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, characterized in that:

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

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

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

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

2. The method as claimed in claim 1, characterized in that processing comprises ignoring the MCW-FLAB1, if a MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is not received and the supplemental field value is set to ‘

0’

.

3. The method as claimed in claim 1, characterized in that processing comprises using the MCW-FLAB1 and the MCW-FLAB2, if the MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is received and the supplemental field value is set to ‘

0’

.

4. The method as claimed in claim 1, characterized in that processing comprises updating packet formats for layer 2 and above according to MCW-FLAB2, if supplemental field value is set to ‘

1’

.

5. The method as claimed in 1, characterized in that processing comprises using the current packet format for layer 2 and above, provided there is an existing assignment of type MCWFLAB if the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame is not received and the supplemental field value is set to ‘

1’

.

6. A computer-readable medium including instructions stored thereon, characterized in that:

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

a third set of instructions for determining whether a Multi Code Word Forward Link Assignment Block 2 (MCW-FLAB2) is received with 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 computer-readable medium as claimed in claim 6, characterized in that a fifth set of instructions for ignoring the MCW-FLAB1 if a MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is not received and the supplemental field value is set to ‘

0’

.

8. The computer-readable medium as claimed in claim 6, characterized in that a sixth set of instructions for using the MCW-FLAB1 and the MCW-FLAB2, if the MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is received and the supplemental field value is set to ‘

0’

.

9. The computer-readable medium as claimed in claim 6, characterized in that a seventh set of instructions for updating packet formats for layer 2 and above according to MCW-FLAB2, if supplemental field value is set to ‘

1’

.

10. The computer-readable medium as claimed in claim 6, characterized in that an eighth set of instructions for using the current packet format for layer 2 and above, provided there is an existing assignment of type MCWFLAB if the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame is not received and the supplemental field value is set to ‘

1’

.

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

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

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

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

means for processing 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, characterized in that having means for ignoring the MCW-FLAB1, if a MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is not received and the supplemental field value is set to ‘

0’

.

13. The apparatus as claimed in claim 11, characterized in that having means for using the MCW-FLAB1 and the MCW-FLAB2, if the MCW-FLAB2 with the MACID for the access terminal in the same PHY channel is received and the supplemental field value is set to ‘

0’

.

14. The apparatus as claimed in claim 11, characterized in that having means for updating packet formats for layer 2 and above according to MCW-FLAB2, if supplemental field value is set to ‘

1’

.

15. The apparatus as claimed in claim 11, characterized in that having means for using the current packet format for layer 2 and above, provided there is an existing assignment of type MCWFLAB if the MCW-FLAB2 with the MACID for the access terminal in the same PHY frame is not received and the supplemental field value is set to ‘

1’
