Abstract: Provided are a method and a base station for controlling mobility of UE. The method may include receiving, by a CU, a measurement report from a UE through a DU; sending, by the CU, a UE context setup request message to a target DU to create a UE context and set a bearer up; sending, by the target DU, a UE context setup response message to the CU to inform the CU of completion of creating the UE context and setting up a bearer; sending, by the CU, a UE context modification request message including a RRC connection reconfiguration message to the source DU; performing, by the target DU, a random access procedure with the UE; and forwarding, by the target DU, an RRC to connection reconfiguration complete message received from the UE to the CU.

Abstract: Provided are a method of a central unit (CU) included in a gNB for managing radio resources and an apparatus thereof. The method may include generating a UE context setup message to be transmitted to one or more distributed units (DUs) associated with the central unit, transmitting the UE context setup message to the one or more DUs through a fronthaul interface, and receiving a response message for the UE context setup message from the one or more DUs through the fronthaul interface.

Abstract: Provided is a method for transmitting and receiving message through a message transfer technology that uses a fronthaul interface between a central unit (CU) and a distributed unit (DU) configuring a 5G base station. The method includes generating a downlink message to be transmitted to one or more DUs associated with the CU, transmitting the downlink message to the one or more DUs through a fronthaul interface, and receiving an uplink message from the one or more DUs through the fronthaul interface.

Abstract: Provided is a method for managing a packet data unit (PDU) session between a base station and a core network in a next generation/5G radio access network (hereinafter, also referred to as NR (New Radio)). The method may include determining whether a requirement of a quality of service (QoS) flow for a terminal is satisfied, transmitting, to a core network entity, a PDU session resource notification message indicating that the requirement is not satisfied when the requirement is not satisfied, receiving one of a PDU session resource modification message and a PDU session resource release message from the core network entity, and transmitting a processing result on one of the PDU session resource modification message and the PDU session resource release message to the core network entity.

Abstract: Provided are a method and an apparatus for processing handover between 5G base stations, which support beamforming and interwork with a 5G core network system in a next-generation/radio access network. The method of processing handover in a base station includes: receiving radio quality measurement information on a plurality of cells and on beams of the respective cells from a user equipment; determining whether handover is required based on the radio quality measurement information and transmitting a handover required message to a core network entity when it is determined that handover is required; and receiving a handover command message from the core network entity.

Abstract: A mobile terminal is provided that includes a first display module to receive a touch signal and a second display module configured to be extensible. An image and a pointer may be displayed on the second display module if the second display is ejected from the mobile terminal. The pointer may move according to a drag direction and a drag distance corresponding to the touch signal if a touch signal with directivity is detected from the first display module. A character-input operation and/or a search operation may be performed on the image displayed on the second display module using the first display module.

Abstract: A mobile communications terminal for supporting a space-time Hybrid Automatic Repeat reQuest (HARQ) schemes and a method thereof, are discussed. According to an embodiment, the mobile communications terminal includes an encoder for encoding data inputted based upon at least one preset puncturing table, and a mapper/modulator for mapping the encoded data to a physical channel and modulating the mapped data.
