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 of managing an assignment of one or more resources in a scheduled data transmission system, the method comprising:

selecting an erasure signature packet;

transmitting a sticky assignment of an assigned channel resource for undetermined duration;

transmitting a first data transmission on the assigned channel resource during the sticky assignment;

transmitting a second data transmission on the assigned channel resource during the sticky assignment;

actively determining presence of a gap between the first data transmission and the second data transmission; and

filling the gap between the first data transmission and the second data transmission by continuously transmitting the erasure signature packet on the assigned channel resource when no other packet of data is available to transmit, the assigned channel resource staying available during transmission of the first data transmission, the second data transmission and/or transmission of the erasure signature packet;

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.

2. The method as claimed in claim 1, further comprising re-assigning said assigned channel resource if it is determined that a packet error occurred while processing data transmitted on said assigned channel resource.

3. The method as claimed in claim 1, further comprising expiring said assigned channel resource by not transmitting any data packet or the erasure signature packet.

4. A method of managing assignment of resources in a communication system, the method comprising:

receiving a first data transmission on an assigned channel resource during a sticky assignment of the assigned channel resource;

receiving a second data transmission on the assigned channel resource during the sticky assignment of the assigned channel resource;

receiving at least one erasure signature packet on the assigned resource, the at least one erasure signature packet filling a gap between the first data transmission and the second data transmission;

determining presence of the gap between the first data transmission and the second data transmission in response to receiving the at least one erasure signature packet; and

maintaining assignment of the assigned channel resource upon receiving the at least one erasure signature packet

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.

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

selecting an erasure signature packet;

means for transmitting a sticky assignment of an assigned channel resource for undetermined duration;

means for transmitting a first data transmission on the assigned channel resource during the sticky assignment;

means for transmitting a second data transmission on the assigned channel resource during the sticky assignment;

means for actively determining presence of a gap between the first data transmission and the second data transmission; and

means for filling the gap between the first data transmission and the second data transmission by continuously transmitting the erasure signature packet on the assigned channel resource when no other packet of data is available to transmit, the assigned channel resource staying available during transmission of the first data transmission, the second data transmission and/or transmission of the erasure signature packet;

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.

6. The apparatus as claimed in claim 5, further comprising means for re-assigning said assigned channel resource if determined that a packet error occurred while processing data transmitted on said assigned channel resource.

7. The apparatus as claimed in claim 5, further comprising means for expiring said assigned channel resource by not transmitting any data packet or the erasure signature packet.

8. An apparatus configured to manage assignment of resources in a communication system, the apparatus comprising:

means for receiving a first data transmission on an assigned channel resource during a sticky assignment of the assigned channel resource;

means for receiving a second data transmission on the assigned channel resource during the sticky assignment of the assigned channel resource;

means for receiving at least one erasure signature packet on the assigned resource, the at least one erasure signature packet filling a gap between the first data transmission and the second data transmission;

means for determining presence of the gap between the first data transmission and the second data transmission in response to receiving the at least one erasure signature packet; and

means for maintaining assignment of the assigned channel resource upon receiving the at least one erasure signature packet

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.

9. In a scheduled data transmission system, an apparatus comprising:

an electronic device configured to manage assignment of one or more resources, configured to select an erasure signature packet,

configured to transmit a sticky assignment of an assigned channel resource for undetermined duration;

configured to transmit a first data transmission on the assigned channel resource during the sticky assignment;

configured to transmit a second data assignment on the assigned channel resource during the sticky assignment;

configured to actively determine the presence of a gap between the first data transmission and the second data transmission; and

configured to fill the gap between the first data transmission and the second data transmission by continuously transmitting the erasure signature packet on the assigned channel resource when no other packet of data is available to transmit, the assigned channel resource staying available during transmission of the first data transmission, the second data transmission and/or transmission of the erasure signature packet;

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.

10. The apparatus as claimed in claim 9, wherein said electronic device is further configured to re-assign said assigned channel resource if it is determined that a packet error occurred while processing data transmitted on said assigned channel resource.

11. The apparatus as claimed in claim 9, wherein said electronic device is further configured to expire said assigned channel resource by not transmitting any data packet or the erasure signature packet.

12. In a scheduled data transmission system, an apparatus comprising:

an electronic device configured to manage assignment of one or more resources;

configured to receive a first data transmission on an assigned channel resource during a sticky assignment of the assigned channel resource;

configured to receive a second data transmission on the assigned channel resource during the sticky assignment of the assigned channel resource;

configured to receive at least one erasure signature packet on the assigned resource, the at least one erasure signature packet filling a gap between the first data transmission and the second data transmission;

configured to determine presence of the gap between the first data transmission and the second data transmission in response to receiving the at least one erasure signature packet; and

configured to maintain assignment of the assigned channel resource upon receiving the at least one erasure signature packet;

wherein the at least one erasure signature packet comprises one or more information bits that cause assignment of the assigned channel resource to be maintained.
