20130343468 | BROADCASTING SIGNAL TRANSMITTER/RECEIVER AND BROADCASTING SIGNAL TRANSMISSION/RECEPTION METHOD - A broadcasting signal reception method according to the present invention comprises the following steps: OFDM-demodulating by receiving a plurality of broadcasting signals, which contain a transmission frame for transmitting a broadcasting service; outputting the transmission frame by decoding a plurality of OFDM-demodulated broadcasting signals with at least one method among MIMO, MISO, and SISO; and selectively decoding a plurality of PLP's, which are included in the transmission frame, using signaling information included in the transmission frame. In particular, PSI/SI such as PAT/PMT can be transmitted through an arbitrary PLP among the plurality of PLP's; and in the transmitter, an arbitrary PLP, which transmits the PAT/PMP, can be decoded first to enable a search of all PLP's that transmit components included in a single broadcasting service, and a plurality of PLP's can be decoded selectively. | 12-26-2013 |
20130315135 | METHOD AND DEVICE FOR SETTING BACKHAUL LINK SUBFRAME IN WIRELESS COMMUNICATION SYSTEM HAVING CARRIER AGGREGATION TECHNIQUE APPLIED THERETO - Disclosed in the present invention is a method for a base station to set a backhaul link subframe for a relay node in a wireless communication system, to which a carrier aggregation technique is applied. More particularly, the present invention comprises the steps of: determining one of the plurality of subframe settings as a first subframe setting for a main component carrier allocated to the relay node; composing subframe setting candidates for one or more subcomponent carriers allocated to the relay node, one the basis of the determined first subframe setting; and determining a second subframe setting for each of the one or more subcomponent carriers, using the composed subframe setting candidates, wherein a subframe aggregation according to the first subframe setting and subframe aggregations according to each of the subframe setting candidates do not overlap when downlink subframes and uplink subframes of the different component carriers are identical, and a downlink subframe aggregation according to the second subframe setting is included in a downlink subframe aggregation according to the first subframe setting. | 11-28-2013 |
20130260779 | METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR - The present application relates to a method for enabling a terminal to transmit channel status information in a wireless communication system. Specifically, the method for enabling the terminal to transmit the channel status information in the wireless communication system includes the steps of: receiving a reference signal from a serving cell or an adjacent cell; determining the priority of the predetermined precoding matrix index (PMI) based on the reference signal; and transmitting the PMI together with a stacking flag to the serving cell according to the priority, wherein the number of PMI to be transmitted to the serving cell is determined based on a size of a buffer commonly set in the serving cell and the terminal, and the stacking flag indicates storing the PMI into the buffer or initializing the buffer. | 10-03-2013 |
20130022017 | METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM - The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control information through a PUCCH in a wireless communication system and an apparatus for same comprising the steps of: obtaining a plurality of second modulation symbol streams corresponding to a plurality of SC-FDMA (Single Carrier Frequency Division Multiplexing) symbols by diffusing a plurality of first modulation symbol streams to form the first modulation symbol streams corresponding to the SC-FDMA symbols within a first slot; obtaining a plurality of complex symbol streams by performing a DFT (Discrete Fourier Transform) pre-coding process for the plurality of second modulation symbol streams; and transmitting the plurality of complex symbol streams through the PUCCH wherein the plurality of second modulation symbol streams are scrambled in a SC-FDMA symbol level. | 01-24-2013 |
