20080224187 | Image Sensor Pixel and Method of Fabricating the Same - A new structure of a photodiode of a pixel in CMOS image sensor and a method of fabricating the same are provided. The photodiode is fabricated by using one photo mask, so that the number of masks decreases and the fabrication processes are simplified. In addition, two conducting layers constituting a photodiode are self-aligned, so that a fabrication process for connecting the photodiode and a transfer transistor is not required. Accordingly, a problem of channeling generated in a lower portion of a gate of the transfer transistor can be solved, so that an improved pixel can be fabricated. | 09-18-2008 |

The 3T-4S step & repeat unit cell includes first to fourth photodiodes. A first shared image sensor unit cell is obtained by combining the first and second photodiodes with four transistors. A second shared image sensor unit cell is obtained by combining the third and fourth photodiodes with four transistors. Signals corresponding to images incident onto the first and second photodiodes are output through a first common detection line. Signals corresponding to images incident onto the third and fourth photodiodes are output through a second common detection line. A terminal of each of the four photodiodes is connected to a first voltage source. Conversion voltages corresponding to image signals incident onto two photodiodes via green filters are output through a common detection line. Conversion voltages corresponding to image signals incident onto the other two photodiodes via red and blue filters are output through another common detection line. | 08-12-2010 |

20100111016 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING PACKET DATA UNIT IN MOBILE COMMUNICATION SYSTEM - The present invention relates to a mobile communication system, and in particular, to a method and apparatus for transmitting and receiving a PDU including an Extension Bit field and a Length Indicator field in a UE or a Node B. A method for transmitting a PDU generated with more than two SDUs and a header having information on each SDU in a transmitter of a mobile communication system is provided. The method includes generating, in the header, a Length Indicator (LI) indicating an end point of each of remaining SDUs except for the last SDU and an Extension Bit indicating the presence/absence of another LI after each LI, and generating the header so that the LI succeeds the Extension Bit associated therewith; generating the PDU with the generated header and the SDUs; and transmitting the PDU. | 05-06-2010 |
20150049675 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING PACKET DATA UNIT IN MOBILE COMMUNICATION SYSTEM - 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. | 02-19-2015 |

20080219204 | APPARATUS AND METHOD FOR REQUESTING PACKET RETRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM - A method for requesting packet retransmission in a wireless communication system is provided. The method includes checking, by a receiving-side Automatic Retransmission reQuest (ARQ) layer, sequence numbers of received packets to determine whether there is any missing packet, and starting a first timer in association with the missing packet; stopping the first timer upon receiving an Hybrid ARQ (HARQ) reception failure indicator corresponding to the missing packet, provided from a receiving-side HARQ layer; and stopping generation of a status report message corresponding to the missing packet, and waiting for an ARQ packet corresponding to the missing packet, retransmitted from a transmitting-side ARQ layer. | 09-11-2008 |
20090046648 | Apparatus and method for generating MAC PDU in mobile communication system - An apparatus and method for avoiding waste of resources by dynamically allocating a length of a Logical Channel IDentification (LCID) of a header included in a Media Access Control (MAC) Protocol Data Unit (PDU) are provided. The apparatus includes a header generator for evaluating a MAC Service Data Unit (SDU) to be multiplexed and for dynamically allocating LCID information according to the evaluated MAC SDU, when radio bearer information is modified. Accordingly, the conventional problem can be solved in which a large number of bits are unnecessarily wasted since the length of the LCID is fixedly allocated or in which logical channels cannot be sufficiently used. | 02-19-2009 |
