Abstract

A method and apparatus are provided to manage the assignment transmission resource of forward and reserve link that is assigned to transmitting entity for a period of time. An indication of a gap is provided whenever the transmitting entity is not transmitting actual data packets (e.g. whole or part of intended data or content), yet the transmitting entity is to maintain the assignment of the allocated resource. For example, an erasure signature packet comprising a first data pattern is transmitted on the assigned resource when there is no actual data to transmit on the assigned resource.

Claims

1. A method for managing an assignment of one or more resources in a scheduled data transmission, the method comprising:

receiving an assignment of a reverse link channel to transmit a data packet, the assignment being valid until a de-assignment of the reverse link channel is received, wherein said reverse link channel continues to be available after transmission of said data packet based upon transmission of one or more packets that cause assignment of the reverse link channel to be maintained prior to said de-assignment, and

transmitting said data packet using said reverse link channel;

wherein the assignment further includes an assignment of a forward link channel, wherein said forward link channel continues to be available after transmission of said data packet based upon transmission of the one or more packets.

2. The method as claimed in claim 1, further comprising expiring said assignment of the reverse link channel by not transmitting said data packet or said one or more packets.

3. The method as claimed in claim 1, wherein the assignment includes the assignment of the forward link channel for an undetermined duration to transmit a second data packet on said forward link channel, wherein said forward link channel continues to be available after transmission of said second data packet based upon transmission of one or more second packets on said forward link channel that cause assignment of the forward link channel to be maintained.

4. The method as claimed in claim 1, further comprising re-assigning said reverse link channel after determining that a packet error occurred while processing data on said reverse link channel.

5. The method as claimed in claim 1, wherein said one or more packets that cause assignment of the reverse link channel to be maintained are transmitted when there is no other packet of data available to transmit.

6. An apparatus configured to manage an assignment of one or more resources in a scheduled data transmission system, the apparatus comprising:

a receiver for receiving an assignment of a reverse link channel to transmit a data packet, the assignment being valid until a de-assignment of the reverse link channel is received, wherein said reverse link channel continues to be available after transmission of said data packet based upon transmission of one or more packets that cause assignment of the reverse link channel to be maintained prior to said de-assignment, and

a transmitter for transmitting said data packet using said reverse link channel;

wherein the assignment includes an assignment of a forward link channel, wherein said forward link channel continues to be available after transmission of said data packet based upon transmission of the one or more packets.

7. The apparatus as claimed in claim 6, further comprising a scheduler configured to expire said assignment of the reverse link channel by not transmitting said data packet or said one or more packets.

8. The apparatus as claimed in claim 6, wherein the assignment includes the assignment of the forward link channel for an undetermined duration to transmit a second data packet, wherein said forward link channel continues to be available after transmission of said second data packet based upon transmission of one or more second packets that cause assignment of the forward link channel to be maintained.

9. The apparatus as claimed in claim 6, further comprising a scheduler configured to re-assign said reverse link channel after determining that a packet error occurred while processing data on said reverse link channel.

10. The apparatus as claimed in claim 6, further comprising a scheduler configured to schedule said one or more packets that cause assignment of the reverse link channel to be maintained when there is no other packet of data is available to transmit.

11. An apparatus configured to manage an assignment of one or more resources in a scheduled data transmission system, the apparatus comprising:

means for receiving an assignment of a reverse link channel to transmit a data packet, the assignment being valid until a de-assignment of the reverse link channel is received, wherein said reverse link channel continues to be available after transmission of said data packet based upon transmission of one or more packets that cause assignment of the reverse link channel to be maintained prior to said de-assignment, and

means for transmitting said data packet using said reverse link channel;

wherein the assignment further includes an assignment of a forward link channel, wherein said forward link channel continues to be available after transmission of said data packet based upon transmission of the one or more packets.

12. The apparatus as claimed in claim 11, further comprising means for expiring said assignment of the reverse link channel by not transmitting said data packet or said one or more packets.

13. The apparatus as claimed in claim 11, wherein the assignment includes the assignment of the forward link channel for an undetermined duration to transmit a second data packet on said forward link channel, wherein said forward link channel continues to be available after transmission of said second data packet based upon transmission of one or more second packets on said forward link channel that cause assignment of the forward link channel to be maintained.

14. A computer program product for wireless communication in a wireless network, comprising:

a non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising;

program code to receive an assignment of a reverse link channel to transmit a data packet, the assignment being valid until a de-assignment of the reverse link channel is received, wherein said reverse link channel continues to be available after transmission of said data packet based upon transmission of one or more packets that cause assignment of the reverse link channel to be maintained prior to said de-assignment; and

program code to transmit said data packet using said reverse link channel;

wherein the resource is a reverse link channel and the assignment further includes an assignment of forward link channel, wherein said forward link channel continues to be available after transmission of said data packet based upon transmission of the one or more packets.

15. The computer program product as claimed in claim 14, code for expiring said assignment of the reverse link channel by not transmitting said data packet or said one or more packets.

16. The computer program product as claimed in claim 14, wherein the assignment includes the assignment of the forward link channel for an undetermined duration to transmit a second data packet on said forward link channel, wherein said forward link channel continues to be available after transmission of said second data packet based upon transmission of one or more second packets on said forward link channel that cause assignment of the forward link channel to be maintained.
