Signal processing method in wireless communication system and device therefor
A method is described for a device to re-establish a connection with a Donor evolved Node B (DeNB). The device communicates with the DeNB via a Un interface using a subframe for the device only. The device detects a problem associated with the Un interface, and performs a radio resource control (RRC) re-establishment procedure to re-establish a RRC connection between the device and the DeNB after detecting the problem associated with the Un interface. The device starts a timer upon detecting the problem associated with the Un interface, and releases a restriction of using the subframe for the device only, if the timer expires. An occurrence of the problem associated with the Un interface is determined in response to receiving consecutive out-of-sync indications.
