Abstract

A method for reconfiguring a parameter of a medium access control layer for a mobile device of a wireless communication system includes, when a radio resource control dedicated signaling for reconfiguration of the parameter is received during activation of the parameter, starting to apply the reconfiguration of the parameter at next opportunity corresponding to the parameter.

Claims

1. A method for reconfiguring a parameter of a medium access control layer for a mobile device of a wireless communication system, the method comprising:

when a radio resource control dedicated signaling comprises a change value for reconfiguration of the parameter is received during activation of the parameter, determining a corresponding operation for the parameter according to the change value;

wherein the parameter is a timer, and determining the corresponding operation for the parameter according to the change value comprises determining whether to continue running of the timer or restart the timer according to the change value, a current value of the timer, and an expiry value of the timer related to the running of the timer;

wherein determining whether to continue the running of the timer or restart the timer according to the change value, the current value of the timer, and the expiry value of the timer related to the running of the timer comprises;

continuing the running of the timer when the change value is larger than or equal to the expiry value;

restarting the timer with a value of (the change value−

(the expiry value−

the current value)) when the change value is smaller than the expiry value and larger than difference of the current value and the expiry value; and

restarting the timer with the change value when the change value is smaller than or equal to the difference of the current value and the expiry value.

2. The method of claim 1, wherein the corresponding operation for the parameter is stopping the activation of the parameter when the change value is “

infinity”

.

3. The method of claim 1 further comprising starting or restarting the timer with the change value when the continued timer or the restarted timer expires.
