Abstract

A method and apparatus of decrementing access terminal assignments in a wireless communication system is provided, comprising determining if a MACID other than the MACID of an access terminal with an assignment for a particular interlace is received and decrementing the access terminal assignments according to the MACID, if the MACID other than the MACID of the access terminal with the assignment for the particular interlace is determined.

Claims

1. A method of decrementing access terminal assignments in a wireless communication system, comprising:

receiving an assignment message with a MACID other than a MACID of an access terminal with an assignment for an interlace; and

decrementing the access terminal assignments according to the assignment message, wherein decrementing the access terminal assignments comprises removing overlapping time and frequency resources between the access terminal assignments and access terminal assignments in the assignment message, and wherein decrementing the access terminal assignments further comprises removing overlapping hop-ports for all access terminal assignments where a ChID and a corresponding interlace in the assignment message overlap with an access terminal assignment for only part of the interlace.

2. The method as claimed in claim 1, wherein decrementing the access terminal assignments further comprises removing all hop-ports in an access terminal assignment for the interlace that intersect with hop-ports specified by a ChID in the assignment message.

3. The method as claimed in claim 1, wherein decrementing the access terminal assignments further comprises removing hop-ports, for all access terminal assignments, that intersect with a ChID and a corresponding interlace in the assignment message.

13. The method of claim 1, wherein receiving the assignment message with the MACID other than the MACID of the access terminal with the assignment for the interlace comprises receiving on a forward link one or more data packets that comprise header information that indicates that the one or more data packets contain the assignment message.

4. A non-transitory computer-readable medium including instructions stored thereon, the instructions comprising:

code for causing an apparatus to receive an assignment message with a MACID other than a MACID of an access terminal with an assignment for an interlace; and

code for causing the apparatus to decrement access terminal assignments according to the assignment message, wherein decrementing the access terminal assignments comprises removing overlapping time and frequency resources between the access terminal assignments and access terminal assignments in the assignment message, and wherein decrementing the access terminal assignments further comprises removing overlapping hop-ports for all access terminal assignments where a ChID and a corresponding interlace in the assignment message overlap with an access terminal assignment for only part of the interlace.

5. The non-transitory computer-readable medium as claimed in claim 4, wherein decrementing the access terminal assignments further comprises removing all hop-ports in an access terminal assignment for the interlace that intersect with hop-ports specified by a ChID in the assignment message.

6. The non-transitory computer-readable medium as claimed in claim 4, wherein decrementing the access terminal assignments further comprises removing hop-ports, for all access terminal assignments, that intersect with a ChID and a corresponding interlace in the assignment message.

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

means for receiving an assignment message with a MACID other than a MACID of an access terminal with an assignment for an interlace; and

means for decrementing access terminal assignments according to the assignment message, wherein the means for decrementing the access terminal assignments comprises means for removing overlapping time and frequency resources between the access terminal assignments and access terminal assignments in the assignment message, and wherein the means for decrementinq the access terminal assignments further comprises means for removing overlapping hop-ports for all access terminal assignments where a ChID and a corresponding interlace overlap with an access terminal assignment for only part of the interlace.

8. The apparatus as claimed in claim 7, wherein the means for decrementing the access terminal assignments further comprises means for removing all hop-ports in an access terminal assignment for the interlace that intersect with hop-ports specified by a ChID in the assignment message.

9. The apparatus as claimed in claim 7, wherein the means for decrementing the access terminal assignments further comprises means for removing hop-ports, for all access terminal assignments, that intersect with a ChID and a corresponding interlace in the assignment message.

10. An apparatus operable in a wireless communication system comprising:

memory; and

a processor configured to;

receive an assignment message with a MACID other than a MACID of an access terminal with an assignment for an interlace; and

decrement access terminal assignments according to the assignment message, wherein decrementing the access terminal assignments comprises removing overlapping time and frequency resources between the access terminal assignments and access terminal assignments in the assignment message, and wherein decrementing the access terminal assignments further comprises removing overlapping hop-ports for all access terminal assignments where a ChID and a corresponding interlace overlap with an access terminal assignment for only part of the interlace.

11. The apparatus as claimed in claim 10, wherein decrementing the access terminal assignments further comprises removing all hop-ports in an access terminal assignment for the interlace that intersect with hop-ports specified by a ChID in the assignment message.

12. The apparatus as claimed in claim 10, wherein decrementing the access terminal assignments further comprises removing hop-ports, for all access terminal assignments, that intersect with a ChID and a corresponding interlace in the assignment message.
