APPARATUS AND METHOD FOR TRANSMITTING CONTROL INFORMATION ON IN-DEVICE COEXISTENCE INTERFERENCE

摘要

The present invention relates to an apparatus and a method for transmitting control information about in-device coexistence interference. The present invention provides a method that a UE generates assistant information indicating occurrence or a probability of occurrence of the interference, and transmits the assistant information to an eNodeB. The eNodeB transmits responding information allowing to enter an avoiding state or release request information indicating releasing the avoiding state corresponding to the assistant information to the UE. The UE releases the avoiding state. According to the present invention, while a UE avoiding an interference delicate frequency band due to in-device coexistence interference, a procedure for re-allocation of an interference delicate frequency band or hand-over to the interference delicate frequency band for the UE is made clear; and a eNodeB can separately release an avoiding state against the interference delicate frequency band without assistance of the UE.
