| 20100115380 | METHOD OF GENERATING CODEWORD IN WIRELESS COMMUNICATION SYSTEM - A method of generating a codeword for a control signal in a wireless communication system is provided. The method includes preparing a control signal and generating a codeword by applying a Reed-Muller (RM) extension matrix to the control signal. The RM extension matrix is generated by extending a RM basic matrix. A control signal can reliably be transmitted by the codeword with low complexity. | 05-06-2010 |

| 20110200132 | MULTI-CELL BASED METHOD FOR APPLYING MULTI-CELL MIMO - The present invention relates a method for transmitting and receiving data in a mobile communication system. More specifically, the invention relates to a method through which a terminal in a cell boundary receives data in a mobile communication system that supports MIMO (Multi Input Multi Output). The method comprises: a step for receiving a first data stream transmitted through multiple transmission antennas from a serving base station, a step for pre-coding a second data stream to make the time delay of the second data stream be different from that of the first data stream and receiving the second data stream from a collaborating base station, and a step for restoring the data based on the first and second data streams. | 08-18-2011 |

| 20090238298 | Method for transmitting and receiving precoded signal in MIMO communication system - A method for transmitting and receiving a precoded signal in a Multi-Input Multi-Output (MIMO) communication system is provided. In the method, a preceding matrix is selected from a codebook including one or more preceding matrices of each rank, each of the preceding matrices including a unitary matrix modified by an antenna selection element. A signal for transmission is then precoded by applying the selected preceding matrix to the signal for transmission and the precoded signal is transmitted through a selected antenna. | 09-24-2009 |
| 20090262845 | Method for transmitting and receiving data using pilot structure - A method for efficiently transmitting and receiving data in a wireless access system and a pilot allocation structure for the same are provided. In the method, data is transmitted using a resource block constructed taking into consideration channel estimation capabilities and data transfer rate and data is received using the resource block. The resource block includes a predetermined number of pilot symbols constructed in a predetermined pattern and the pilot symbols are allocated to the resource block at a predetermined allocation rate taking into consideration the number of transmit antennas. | 10-22-2009 |
| 20090279632 | Method for achieving transmission diversity in a multiple antenna system - A method for achieving transmission diversity in a multiple antenna system is disclosed. The transmission diversity method includes selecting a column vector from a matrix DETERMINED according to a resource index and a current rank, and multiplying the selected column vector by a transmission symbol. | 11-12-2009 |

| 20110032878 | METHOD FOR TRANSMITTING BAND BITMAP IN WIRELESS COMMUNICATION SYSTEM - A method for transmitting a band bitmap in a wireless communication system is provided. The method includes selecting at least one selection band from a plurality of bands, the plurality of bands being distributed throughout a whole frequency band, grouping the plurality of bands into a plurality of band groups, setting a primary bitmap for each band group according to whether the selection band is included in each band group and setting a secondary bitmap for bands in each band group, and transmitting the primary bitmap and the secondary bitmap. Radio resources used to transmit a band bitmap can be reduced by decreasing the number of bits of the band bitmap. | 02-10-2011 |
