Optimization of uplink resource grant procedure and apparatus

1. A method, comprising:

receiving a radio resource control message for which a response message is required to be transmitted to a network access node;

performing at least one procedure specified by the radio resource control message;

initiating operation of a timer;

receiving a specification of the network radio resources from the network access node;

terminating operation of the timer; and

transmitting the response message using the specified network radio resources, wherein the response message includes a value of the timer when operation of the timer is terminated.

2. A method, comprising:

receiving a radio resource control message for which a response message is required to be transmitted to a network access node;

performing at least one procedure specified by the radio resource control message, wherein performing the at least one procedure comprises delaying for a predetermined period of time after performing the at least one procedure;

beginning to monitor a downlink control channel for a specification of the network radio resources from the network access node; and

transmitting the response message using the specified network radio resources.

3. The method of claim 2 , wherein the predetermined period of time is configured to be a radio resource control procedure delay period.

4. The method of claim 2 , wherein the predetermined period of time is configured to be equal to a user equipment capability to respond to the radio resource control message.

5. An apparatus, comprising a controller configured to operate with a radio frequency receiver and a radio frequency transmitter, said controller further configured to receive a radio resource control message for which a response message is required to be transmitted to a network access node, said controller further configured to perform at least one procedure specified by the radio resource control message and to transmit the response message using network radio resources that are received in a non-solicited manner from the network access node, the apparatus further comprising a timer, said controller being further configured to initiate operation of the timer when performing the at least one procedure, to receive a specification of the network radio resources from the network access node and in response to terminate operation of the timer and to transmit the response message using the specified network radio resources, wherein the response message comprises a value of the timer when operation of the timer is terminated.

6. An apparatus, comprising a controller configured to operate with a radio frequency receiver and a radio frequency transmitter, said controller further configured to receive a radio resource control message for which a response message is required to be transmitted to a network access node, said controller further configured to perform at least one procedure specified by the radio resource control message and to transmit the response message using network radio resources that are received in a non-solicited manner from the network access node, wherein said controller, when performing the at least one procedure, is further configured to delay for a predetermined period of time after performing the at least one procedure, to begin to monitor a downlink control channel for a specification of the network radio resources from the network access node and to transmit the response message using the specified network radio resources.

7. The apparatus of claim 6 , where the predetermined period of time is configured to be a radio resource control procedure delay period, or is configured to be equal to a user equipment capability to respond to the radio resource control message.

8. An apparatus, comprising a controller configured to operate with a radio frequency receiver and a radio frequency transmitter, said controller further configured to transmit a radio resource control message for which a response message is required to be received from a user equipment, said controller further configured to specify to the user equipment in an un-solicited manner those network radio resources to be used by the user equipment for transmitting the response message, wherein said controller transmits a specification of the radio resources subsequent to a delay period after transmitting the radio resource control message, wherein the delay period is one of predetermined or based at least in part on information received from the user equipment.

9. A method, comprising:

transmitting a radio resource control message for which a response message is required to be received from a user equipment; and

specifying to the user equipment in an un-solicited manner those network radio resources to be used by the user equipment for transmitting the response message, wherein specifying comprises transmitting a specification of the radio resources subsequent to a delay period after transmitting the radio resource control message, wherein the delay period is one of predetermined or based at least in part on information received from the user equipment.

10. A non-transitory computer-readable medium configured with program instructions, the program instructions together with at least one memory and at least one processor, configured to cause an apparatus to:

receive a radio resource control message for which a response message is required to be transmitted to a network access node;

perform at least one procedure specified by the radio resource control message;

initiate operation of a timer;

receive a specification of the network radio resources from the network access node;

terminate operation of the timer; and

transmit the response message using the specified network radio resources, wherein the response message includes a value of the timer when operation of the timer is terminated.

11. A non-transitory computer-readable medium configured with program instructions, the program instructions together with at least one memory and at least one processor, configured to cause an apparatus to:

receive a radio resource control message for which a response message is required to be transmitted to a network access node;

perform at least one procedure specified by the radio resource control message;

delay for a predetermined period of time after performing the at least one procedure;

monitor a downlink control channel for a specification of the network radio resources from the network access node; and

transmit the response message using the specified network radio resources.
