20140169266 | APPARATUS AND METHOD FOR TRANSMITTING UPLINK INFORMATION IN A BROADCASTING SYSTEM - An apparatus and a method for transmitting uplink information in a broadcasting system are provided. A repeater of a mobile broadcasting system includes a plurality of transmitting stations each transmitting a broadcast signal for at least one broadcast service, a plurality of terminals receiving the broadcast signal for the at least one broadcast service through at least one transmitting station among the transmitting stations, and the repeater, the repeated being coupled between the plurality of transmitting stations and the plurality of terminals. The repeater includes a receiving unit configured to receive uplink information from the terminals, a control unit configured to classify the received uplink information by broadcast service and to create uplink information per broadcast service, and a transmitting unit configured to transmit the created uplink information to at least one corresponding transmitting station. | 06-19-2014 |
20140169293 | METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING RESPONSE SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for transmitting and receiving a response signal in a wireless communication system are provided. In a method for transmitting a response signal in a broadcasting system, Acknowledgement (ACK) information for uplink packet data for each user is generated. A symbol and a subcarrier which will transmit the ACK information for each user inside a transmission frame are determined. ACK transmission related information is transmitted via a control channel inside the transmission frame. The ACK information for each user is transmitted via the determined symbol and subcarrier inside the transmission frame. | 06-19-2014 |
20140286248 | METHOD AND APPARATUS FOR REDUCING PEAK-TO-AVERAGE POWER RATIO IN SINGLE CARRIER-FREQUENCY DIVISION MULTIPLE ACCESS BASED RADIO COMMUNICATION SYSTEM - A method for reducing Peak-to-Average Power Ratio (PAPR) in a Single Carrier Frequency Division Multiple Access (SC-FDMA) based radio communication system is provided. The method includes arranging symbols mapped to predetermined sub-carrier allocation types such that phases of the symbols do not overlap, and transmitting the arranged symbols. | 09-25-2014 |
20140355512 | RELAY APPARATUS, RECEIVING APPARATUS AND CONTROL METHOD THEREOF - A relay apparatus relays a signal received from a transmitting apparatus to a receiving apparatus, and includes a receiver configured to receive a signal from the transmitting apparatus, and a transmitter configured to repeatedly transmit a predetermined symbol interval of the received signal to the receiving apparatus. | 12-04-2014 |
20140375890 | TRANSMITTING APPARATUS AND RECEIVING APPARATUS AND CONTROL METHOD THEREOF - A transmitting apparatus is provided. The transmitting apparatus includes: a frame generator configured to generate a first frame provided for a fixed terminal and a second frame provided for a mobile terminal, the second frame including common service data commonly provided for the fixed terminal and the mobile terminal; an information inserting unit configured to insert access information on the common service data into a signaling area of the first frame; and a transmitter configured to transmit the first and second frames. | 12-25-2014 |
20150049773 | TRANSMITTING APPARATUS, RECEIVING APPARATUS, AND DATA PROCESSING METHOD THEREOF - A data processing method of a transmitting apparatus includes generating a frame including at least one data packet, inserting, using the transmitting apparatus, a header including information associated with a data field occupied by the at least one data packet into the frame, and transmitting, to a receiving apparatus, the frame into which the header is inserted, wherein the information associated with the data field includes first information indicating whether a start byte of a first data packet is included in the data field and second information indicating whether an end byte of a last data packet is included in the data field. | 02-19-2015 |
20150071373 | TRANSMITTING APPARATUS, RECEIVING APPARATUS AND CONTROL METHODS THEREOF - A transmitting apparatus, a receiving apparatus and a method of controlling these apparatus are provided. The transmitting apparatus includes: a frame generator configured to generate a plurality of frames which include one or more kinds of data; a preamble symbol inserter configured to insert at least one preamble symbol in each of the plurality of frames, and insert, in a preamble symbol of a frame, location information about at least one frame, among the plurality of frames, which includes a same kind of data as a kind of data included in the frame; and a transmitter configured to transmit the plurality of frames in each of which the preamble symbol is inserted. | 03-12-2015 |
20150092882 | TRANSMITTING APPARATUS, RECEIVING APPARATUS, AND CONTROL METHODS THEREOF - A transmitting apparatus, a receiving apparatus and methods of controlling these apparatuses are provided. The transmitting apparatus includes: an input processor configured to process a plurality of input streams to generate a plurality of base band frames; a bit interleaved and coded modulation (BICM) processor configured to perform forward error correction (FEC) coding, constellation mapping, and interleaving on the plurality of baseband frames; a symbol generator configured to add signaling data to the plurality of baseband frames output from the BICM processor to generate an orthogonal frequency division multiplexing (OFDM) symbol; and a transmitter configured to select at least one of a plurality of pilot patterns based on a fast Fourier transform (FFT) size and a guard interval fraction, insert a pilot in the OFDM symbol according to the selected pilot pattern, and transmit a stream including the pilot-inserted OFDM symbol. Thus, a data transmission rate is increased and accurate channel estimation is performed, through inserting different pilots according to different FFT sizes and guard interval fractions. | 04-02-2015 |
20150095943 | TRANSMITTER, RECEIVER, AND CONTROLLING METHOD THEREOF - A transmitter and a receiver of data frames and related methods are disclosed. The transmitter includes: a frame generator configured to generate a first frame comprising data to be transmitted; and a preamble inserter configured to insert a preamble into the first frame, wherein the preamble inserter is further configured to insert, in the preamble, emergency alert service (EAS) information related to a preset emergency alert event, and set an indicator in the frame to indicate whether the EAS information is inserted in the preamble. Accordingly, only important information related to the EAS is transmitted in the form of a preamble to achieve robust transmission, and L1 information of related data is directly transmitted to reduce power consumption. | 04-02-2015 |
