1. A method in a communication system comprising the steps of, at a user agent:
- receiving a random access response message from an access device;
receiving a radio resource control (RRC) configuration message from the access device after receiving the random access response message, the RRC configuration message including a configuration of at least one uplink control channel resource;
where uplink time synchronization at the user agent has been lost when the RRC configuration message is received, using at least a portion of the RRC configuration message information to configure the user agent; and
after time synchronization has been restored, communicating with the access device.

Abstract
A method and apparatus for use in a communication system, the method comprising the steps of, at a user agent receiving a configuration message from an access device, where uplink time synchronization at the user agent has been lost when the configuration message is received, using at least a portion of the configuration message information to configure the user agent and after time synchronization has been restored, communicating with the access device.

1. A method in a communication system comprising the steps of, at a user agent:
-
receiving a random access response message from an access device; receiving a radio resource control (RRC) configuration message from the access device after receiving the random access response message, the RRC configuration message including a configuration of at least one uplink control channel resource; where uplink time synchronization at the user agent has been lost when the RRC configuration message is received, using at least a portion of the RRC configuration message information to configure the user agent; and after time synchronization has been restored, communicating with the access device. - View Dependent Claims (2, 3, 15)

4. A method in a communication system comprising the steps of, at a user agent:
-
receiving a random access response message from an access device; receiving a radio resource control (RRC) configuration message from the access device after receiving the random access response message, the RRC configuration message including a configuration of at least one uplink control channel resource; where uplink time synchronization at the user agent has been lost when the RRC configuration message is received and after time synchronization has been restored, using at least a portion of the RRC configuration message information to configure the user agent, and communicating with the access device using the configuration received in the message. - View Dependent Claims (16)

5. A method in a communication system where a radio resource control (RRC) configuration message is received at a user agent and includes information indicating how the user agent should be configured to communicate with an access device, the method comprising the steps of, at a user agent:
-
receiving a random access response message from an access device; receiving a RRC configuration message from the access device after receiving the random access response message, the RRC configuration message including a configuration of at least one uplink control channel resource; where uplink time synchronization at the user agent has been lost when the RRC configuration message is received, using the RRC configuration message information to configure the user agent; and suspending communication with the access device until time synchronization has been restored. - View Dependent Claims (6, 7, 17)

8. An apparatus for use in a communication system, the apparatus comprising:
-
a user agent including a processor programmed to perform the steps of; receiving a random access response message from an access device; receiving a radio resource communication (RRC) configuration message from the access device after receiving the random access response message, the RRC configuration message including a configuration of at least one uplink control channel resource; where uplink time synchronization at the user agent has been lost when the RRC configuration message is received, using at least a portion of the RRC configuration message information to configure the user agent; and after time synchronization has been restored, communicating with the access device. - View Dependent Claims (9, 10, 18)
