Abstract: 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.

Abstract: A method of monitoring a control channel in a wireless communication system includes monitoring a physical down-link control channel (PDCCH) during a monitored duration, wherein the monitored duration is a part of a discontinuous reception (DRX) period, the DRX period specifying the periodic repetition of the monitored duration followed by a non-monitored duration. By monitoring a control channel during a DRX period, battery consumption of a user equipment can be reduced and an operation time of the user equipment can be increased.

Abstract: A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.

Abstract: A method and apparatus for applying autonomous denial in a wireless communication system is provided. A user equipment (UE) counts the number of aggregated denials of uplink (UL) subframes in all serving cells or each serving cell over a validity period including previous subframes and a current subframe. If the number of aggregated denials of UL subframes in all serving cells or each serving cell is less than a threshold, the UE is allowed to deny scheduled UL transmission at the current subframe.

Abstract: A method for transmitting and receiving signals in consideration of a time alignment timer and user equipment (UE) for the same are provided. In this method, a UE performs initial transmission or retransmission of an uplink signal using wireless resources corresponding to an uplink grant signal received from a base station only when a time alignment timer of the UE is running. The UE does not transmit a HARQ feedback signal for a downlink signal received from the base station to the base station when the time alignment timer of the UE is not running.

Abstract: A method of efficiently processing a random access response message, when a terminal (or user equipment) performs random access, is disclosed. After the terminal transmits a random access preamble to a base station, the terminal may receive a random access response message having a format of medium access control protocol data unit (MAC PDU) including only a backoff indicator subheader in a MAC header of the MAC PDU, from the base station in response to the random access preamble. As described above, the terminal, which has received the random access response message including only a backoff indicator subheader in the MAC header of the MAC PDU, may consider a random access response reception procedure not successful and may perform a subsequent procedure for a random access responses reception failure.
