摘要:
A method for transmitting information in a mobile communication system using HSDPA (High Speed Downlink Packet Access) service. When an RNC (Radio Network Controller) generates or changes HSDPA service-related information, it transmits the generated or changed information to a Node B and a UE along with an indicator indicating the change in the HSDPA service information. Therefore, the Node B and the UE simultaneously operate by receiving the generated or changed information, resulting in an increase in the HSDPA service efficiency.

A method for resetting a MAC-hs (Medium Access Control-high speed) layer entity in a communication system using HSDPA (High Speed Downlink Packet Access). When an RLC (Radio Link Control) layer entity is reset due to occurrence a protocol error, the system resets both a MAC-hs layer entity of the RLC layer entity and its counterpart RLC, thus preventing unnecessary data transmission.

Disclosed is an apparatus and method for retransmitting data in a mobile communication system. A MAC-h (Medium Access Control-high speed) layer transmits, to an RLC (Radio Link Control) layer, received data and information on whether a retransmission process on errored data is being performed, thereby to prevent the RLC layer from performing duplicated retransmission on the errored data.

An apparatus randomly assigns downlink sub-frame time slots for transmitting user data in an NB-TDD CDMA (Code Division Multiple Access) communication system. In the apparatus, a multiplexer creates a user data part by multiplexing user data for UEs (User Equipments), a TFCI (Transport Format Combination Indicator) symbol for the user data, and a TPC (Transmission Power Control command) symbol for controlling transmission power of a downlink channel, and a controller randomly assigns time slots for transmitting the user data part in the sub-frames, based on a time slot number initially assigned for the user data part, a sub-frame number at a transmission point of the user data part, and the number of assigned uplink time slots in the corresponding sub-frame.

A method and apparatus for transmitting a packet in a mobile communication system. A transmitting side allocates a short sequence number for an initial transmission packet using some bits among bits of a predetermined length for expressing a sequence number of the packet, and sets a first flag indicating use of the short sequence number. The transmitting side inserts the short sequence number and the first flag into the packet, and transmits the packet to a receiving side.

A method for reporting buffer status of a User Equipment (UE) in a mobile communication system is provided. The method for reporting buffer status of the UE in the mobile communication system includes being allocated a transmission resource from a node B; determining information to add to a certain region of a first Medium Access Control (MAC) subheader through an N-th MAC subheader using the transmission resource; generating a MAC Protocol Data Unit (PDU) by concatenating the first MAC subheader through the N-th MAC subheader with corresponding payload elements; and transmitting the generated MAC PDU.

A protrusion of dry-etched pattern of a thin film transistor substrate generated due to a difference between isotropy of wet etching and anisotropy of dry etching is removed by forming a plating part on a surface of the wet etched pattern through an electroless plating method. If the plating part is formed on a data pattern layer of the substrate, the width or the thickness of the data pattern layer may be increased without loss of aperture ratio, the channel length of the semiconductor layer may be reduced under the limit according to the stepper resolution and the protrusion part of the semiconductor layer may be removed. As a result, the aperture ratio may be increased, the resistance may be reduced, and the driving margin may be increased due to rising of the ion current. Furthermore, the so-called water-fall noise phenomenon may be eliminated.
