Abstract

A method for transmission continuation control includes establishing a physical transmission link between a first entity and a second entity, and transmitting a first user message from one of the first and second entities to the other of the first and second entities. The method also includes executing a continuation protocol between the first entity and the second entity while maintaining the physical transmission link. The method further includes transmitting a second user message from one of the first and second entities to the other of the first and second entities, and terminating the physical transmission link between the first entity and the second entity after the transmission of the second user message.

Claims

1. A method for transmission continuation control, comprising:

establishing a physical transmission link between a first entity and a second entity;

transmitting a first user message from one of said first and second entities to the other of said first and second entities;

executing a continuation protocol between said first entity and said second entity while maintaining said physical transmission link;

transmitting a second user message from one of said first and second entities to the other of said first and second entities; and

terminating said physical transmission link between said first entity and said second entity after the transmission of said second user message.

2. The method for transmission continuation control of claim 1, wherein said first user message and said second user message comprise packet data.

3. The method for transmission continuation control of claim 1, wherein said execution of said continuation protocol comprises transmitting a control message between said first entity and said second entity, said control message comprising an uplink channel and a downlink channel for use in the transmission of said second message.

4. The method for transmission continuation control of claim 1, wherein said first entity is a base transceiver station and said second entity is a mobile end station and said physical transmission link comprises an uplink channel and a downlink channel between said base transceiver station and said mobile end station.

5. The method for transmission continuation control of claim 4, wherein said physical transmission link for said second user message transmission is comprised of a downlink channel that is different from said downlink channel of the physical transmission link for said first user message transmission.

6. The method for transmission continuation control of claim 4, wherein said second user message is transmitted from said first entity to said second entity, said method further comprising the step of making a determination to transmit said second user message from said first entity to said second entity, wherein said determination is based on the result of resource allocation algorithms processed by said first entity.

7. The method for transmission continuation control of claim 1, wherein said first entity is a base transceiver station and said second entity is a mobile end station.

8. The method for transmission continuation control of claim 7, wherein said first user message is transmitted from said base transceiver station to said mobile end station and said second user message is transmitted from said mobile end station to said base transceiver station.

9. The method for transmission continuation control of claim 7, wherein said first user message is transmitted from said mobile end station to said base transceiver station and said second user message is transmitted from said base transceiver station to said mobile end station.

10. The method for transmission continuation control of claim 1, wherein said first user message and said second user message are transmitted from said first entity to said second entity.

11. A method for transmission continuation control comprising:

establishing a physical transmission link between a first entity and a second entity;

transmitting a first user message from said first entity to said second entity;

executing a continuation protocol between said first entity and said second entity while maintaining said physical transmission link;

transmitting a second user message from said first entity to said second entity; and

terminating said physical transmission link between said first entity and said second entity subsequent to the transmission of said second user message from said first entity to said second entity.

12. The method for transmission continuation control of claim 11, wherein said first entity is a mobile end station and said second entity is a base transceiver station and said physical transmission link comprises an uplink channel and a downlink channel between said mobile end station and said base transceiver station.

13. The method for transmission continuation control of claim 12, wherein said execution of a continuation protocol comprises:

transmitting a continuation request from said first entity to said second entity; and

transmitting a continuation result from said second entity to said first entity.

14. The method for transmission continuation control of claim 13, wherein said uplink channel comprises a first uplink channel and said downlink channel comprises a first downlink channel, and wherein said continuation result comprises a second uplink channel and a second downlink channel for the transmission of said second user message and said second uplink channel and said second downlink channel thereafter comprise the physical transmission link between said first entity and said second entity.

15. The method for transmission continuation control of claim 13, wherein said establishment of said physical transmission link between said first entity and said second entity comprises the transmission of a poll message from said second entity to said first entity, and wherein said poll message comprises a bit, said bit indicative of whether said first entity may transmit said continuation request to said second entity.

16. The method for transmission continuation control of claim 11, wherein said first entity is a base transceiver station and said second entity is a mobile end station;

said physical transmission link comprises an uplink channel and a downlink channel between said base transceiver station and said mobile end station; and

said execution of a continuation protocol comprises transmitting a continuation notification from said first entity to said second entity, and transmitting a continuation confirmation from said second entity to said first entity.

17. A transmission continuation control protocol for allowing continued data transmission between a first entity and a second entity communicating over a physical transmission link, comprising:

a poll message operable to initiate said transmission continuation control protocol between said first and second entities;

a continuation request operable to request continued data transmission between said first and second entities; and

a continuation result operable to indicate whether said physical transmission link will be maintained to allow for continued data transmission between said first and second entities.

18. The transmission continuation control protocol of claim 17, wherein said poll message comprises a continuation flag field, and said continuation flag field comprises a value indicative of whether said continuation request is transmitted.

19. The transmission continuation control protocol of claim 17, wherein said continuation result comprises an uplink channel and a downlink channel.
