Compressed data is transmitted via the low-rate transmission channel, and loss data that is lost by compression is transmitted via the high-rate transmission channel. An apparatus on a reception side combines, with the loss data, data that is obtained by decompressing the compressed data, and output the combined data. When the loss data cannot be received, the apparatus outputs the data that is obtained by decompressing the compressed data. | 2011-12-29 |

20110317780 | METHOD AND APPARATUS FOR TRANSMITTING SYNCHRONIZATION SIGNAL IN MULTI-NODE SYSTEM - A method of transmitting a synchronization signal in a multi-node system having a plurality of nodes and a base station for controlling the plurality of node is provided. The method includes: generating a synchronization signal sequence; and mapping the generated synchronization signal sequence to a resource element, and thereafter transmitting the mapped synchronization signal sequence to a user equipment via at least one node among the plurality of nodes, wherein the synchronization signal sequence is generated based on an identifier (ID) of a transmission node for transmitting the synchronization signal sequence. | 2011-12-29 |
20110317781 | TRANSMITTER, RECEIVER, DATA TRANSMISSION METHOD AND DATA RECEPTION METHOD - A method is provided which improves reliability of channel estimation in a digital communication system by reducing the ambiguity in the recognition of received symbols evaluated for the channel estimation. A data word transmitted according to a first mapping of data word values to modulation states is re-transmitted at least once with a second, re-arranged mapping of data word values to modulation states. The second mapping and possible further mappings are generated from the first mapping in a way that the number of different results which can be obtained from combining the transmitted original data symbol and the re-transmitted counterpart data symbol(s) is lower than the number of original modulation states in the first mapping. | 2011-12-29 |
