Abstract
A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by allocating a non-interfering downlink signaling channel for downlink reception of interference avoidance instructions at the UE device. In operation, a user equipment device detects IDC interference and sends an IDC indication message to the radio network to get an appropriate solution, but instead of waiting at the current frequency to receive the IDC response from the radio network, the user equipment device moves to a non-interfering downlink signaling channel for downlink reception of interference avoidance instructions.
