Apparatus and method for acquisition of a common enhanced dedicated channel resource

1. An apparatus, comprising:

a processor; and

memory including computer program code,

said memory and said computer program code configured to, with said processor, cause said apparatus to perform at least the following:

generate a first message indicating that data is ready for transmission on an uplink;

initiate a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

receive a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

generate a third message for a radio link control subsystem to proceed as if said radio link control subsystem transmits an uplink radio link control protocol data unit in response to said second message.

2. The apparatus as recited in claim 1 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to start a timer and generate another message indicating that data is ready for transmission on said uplink when said timer runs out.

3. The apparatus as recited in claim 1 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to manipulate protocol variables and timers as if said radio link control subsystem transmits said uplink radio link control protocol data unit in response to said second message.

4. The apparatus as recited in claim 1 wherein said third message informs said radio link control subsystem of a failure to acquire said uplink communication resource.

5. The apparatus as recited in claim 1 wherein said uplink communication resource is a common enhanced dedicated channel communication resource.

6. The apparatus as recited in claim 1 wherein said third message is a new or existing message type.

7. A computer program product including a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, comprising:

code for generating a first message indicating that data is ready for transmission on an uplink;

code for initiating a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

code for receiving a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

code for generating a third message for a radio link control subsystem to proceed as if said radio link control subsystem transmits an uplink radio link control protocol data unit in response to said second message.

8. A method, comprising:

generating a first message indicating that data is ready for transmission on an uplink; initiating a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

receiving a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

generating a third message for a radio link control subsystem to proceed as if said radio link control subsystem transmits an uplink radio link control protocol data unit in response to said second message.

9. The method as recited in claim 8 further comprising starting a timer and generating another message indicating that data is ready for transmission on said uplink when said timer runs out.

10. The method as recited in claim 8 further comprising manipulating protocol variables and timers as if said radio link control subsystem transmits said uplink radio link control protocol data unit in response to said second message.

11. An apparatus, comprising:

a processor; and

memory including computer program code,

said memory and said computer program code configured to, with said processor, cause said apparatus to perform at least the following:

generate a first message indicating that data is ready for transmission on an uplink;

initiate a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

receive a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

generate a third message for a radio link control subsystem indicating a successful acquisition of said uplink communication resource.

12. The apparatus as recited in claim 11 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to start a timer and generate another message indicating that data is ready for transmission on said uplink when said timer runs out.

13. The apparatus as recited in claim 11 wherein said memory and said computer program code are further configured to, with said processor, cause said apparatus to generate a data request message including an uplink radio link control protocol data unit and manipulate protocol variables and timers.

14. The apparatus as recited in claim 11 wherein said uplink communication resource is a common enhanced dedicated channel communication resource.

15. The apparatus as recited in claim 11 wherein said third message is a status message.

16. The apparatus as recited in claim 11 wherein said third message is a new or existing message type.

17. A computer program product including a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, comprising:

code for generating a first message indicating that data is ready for transmission on an uplink;

code for initiating a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

code for receiving a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

code for generating a third message for a radio link control subsystem indicating a successful acquisition of said uplink communication resource.

18. A method, comprising:

generating a first message indicating that data is ready for transmission on an uplink;

initiating a procedure in a layer 1 subsystem to acquire an uplink communication resource in response to said first message;

receiving a second message from said layer 1 subsystem indicating failure to acquire said uplink communication resource; and

generating a third message for a radio link control subsystem indicating a successful acquisition of said uplink communication resource.

19. The method as recited in claim 18 further comprising starting a timer and generating another message indicating that data is ready for transmission on said uplink when said timer runs out.

20. The method as recited in claim 18 further comprising generating a data request message including an uplink radio link control protocol data unit and manipulating protocol variables and timers.
