Claim of US Patent No. 9,402,263

1. A radio resource control method, comprising:
detecting, by a User Equipment (UE), a Reference Signal Receiving Power (RSRP) of each component carrier;
determining whether a preset requirement for image interference due to power imbalance is met according to a result of the
detection; and

performing a preset image interference avoidance strategy if the preset requirement for image interference due to power imbalance
is met,

wherein performing the preset image interference avoidance strategy comprises:
selecting one of the component carriers whose RSRP is most different from RSRPs of other component carriers as a target component
carrier; and

determining whether the selected target component carrier is a primary component carrier, if yes, switching the primary component
carrier to one of remaining active component carriers having a maximum RSRP, releasing the selected target component carrier
and performing normal communication; otherwise, releasing the target component carrier and performing normal communication.
