Abstract:
Methods and apparatuses are provided for transmitting and receiving a Packet Data Unit (PDU) in a mobile communication system. The PDU, including a header and at least one data field, is generated. The PDU is transmitted. The header includes a length indicator (LI) field and an extension bit field. The LI field indicates a length of a corresponding data field. The extension bit field indicates whether a data field follows or a set of an extension bit field and an LI field follows. The extension bit field is placed prior to the LI field in the set of the extension bit field and the LI field. An LI field is present for every data field except a last data field.
Abstract:
A device for vacuum evaporating includes a thermal evaporation module that generates vapor in a vacuum chamber through a circular opening by heating a vapor evaporation material accommodated therein. A moving stage is positioned in an atmospheric area separated from the vacuum chamber and adjusts a position of the thermal evaporation module under the thermal evaporation module. A sealing part is combined with the thermal evaporation module to isolate the vacuum chamber and the atmospheric area from each other and maintain a vacuum state of the vacuum chamber while surrounding the thermal evaporation module and permitting movement of the thermal evaporation module.

Abstract:
A method and apparatus are provided for supporting a large Service Data Unit (SDU) in a receiver of a mobile communication system. The method includes receiving a Radio Link Control (RLC) Protocol Data Unit (PDU) from an upper layer; checking a Length Indicator (LI) included in an RLC header of the RLC PDU; if the LI is configured as “0”, determining that the received RLC PDU includes an RLC SDU of 2047 bytes, and if the LI is configured as a value other than “0”, determining that the received RLC PDU includes an RLC SDU of a size corresponding to the value of the LI; and reforming the RLC SDU, based on the LI.
Abstract:
A method for operating a terminal in a wireless communication system is provided. The method includes decoding data which is received data or combined data, in case that the data is successfully decoded, determining whether the decoding of the data is a first successful decoding, and, in case that the decoding of the data is the first successful decoding, delivering the decoded data to a disassembly and demultiplexing entity.
Abstract:
An operating method and an apparatus according to data duplicate retransmission in a mobile communication system are provided. A method of a User Equipment (UE) according to data duplicate retransmission in a mobile communication system includes storing a Media Access Control Protocol Data Unit (MAC PDU) received from an Evolved Node B (ENB) in a soft buffer, decoding the MAC PDU, determining whether the decoding is a first successful decoding of data of the corresponding soft buffer, and determining whether to forward the decoded MAC PDU to an upper layer according to the determination result.
Abstract:
An adaptable antenna apparatus for a base station is provided. The adaptable antenna apparatus includes a first antenna having a first antenna array, a second antenna rotatably coupled to the first antenna and having a second antenna array, and a main controller provided in one of the first antenna and the second antenna, wherein the main controller is configured to apply a control signal to the first antenna and the second antenna.

Abstract:
A method and apparatus for configuring a routing path in a wireless communication system are provided. The method includes measuring a first distance between the terminal and a target terminal, transmitting information of the measured first distance to at least one neighboring terminal, receiving a second distance measured for the target terminal with respect to the terminal from the at least one neighboring terminal, and determining a neighboring terminal of which the second distance is the longest as a next terminal of the routing path.
