    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 for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

    Abstract translation: 公开了一种使用移动通信系统中的用户设备（UE）对基站进行随机接入的方法，所述移动通信系统使用在多个分量载波上进行通信的载波聚合，以及用于该方法的终端。 当UE在应用CA技术的移动通信系统中执行基于竞争的随机接入过程时，UE仅当上行链路许可信号（eNB）接收到来自eNB的上行链路许可信号时，将上行链路授权信号视为竞争解决消息 通过与用于发送随机接入前导码或第三消息的上行链路CC相对应的下行链路CC接收，从而防止争用解决错误结束。

    Abstract: A method and apparatus of managing a radio bearer is disclosed. A relay node (RN) sets up at least one UuRB for a Uu interface between a user equipment (UE) and the RN and a UnRB for a Un interface between the RN and a base station (BS). The at least one UuRB is mapped to the UnRB according to quality of service (QoS) guaranteed by the at least one UuRB to setup a RB between the UE and the BS.

    Abstract: A method and apparatus for supporting a closed subscriber group (CSG) service is provided. The apparatus includes a memory to store CSG subscription information and a processor operatively coupled to the RF unit and memory to implement a radio interface protocol. The processor accesses a base station (BS), transmits the CSG subscription information to the BS, receives an access mode from the BS where the access mode is determined based on the CSG subscription information, and negotiates with the BS with regard to a CSG service if the access mode supports a CSG to which the apparatus belongs.
