20120120903 | METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL FOR REDUCING INTER-CELL INTERFERENCE IN MULTIPLE INPUT MULTIPLE OUTPUT COMMUNICATION SYSTEM - Disclosed is a method for transmitting a reference signal, in a method for transmitting a Channel State Information-Reference Reference Signal (CSI-RS) for measuring a transmission channel according to each antenna and a data signal in a broadband wireless communication system based on a MIMO scheme through a plurality of antennas. | 2012-05-17 |
20120120904 | Method and Apparatus of Scanning Channels in Wireless Local Area Network - A method and apparatus of scanning channels of a white space zone in a wireless local area network is provided. A beacon frame includes a white space map including information about whether each white space channel in the white space zone is occupied by an incumbent user. Channels of the white space zone are scanned based on the white space map. | 2012-05-17 |
20120120905 | METHOD AND DEVICE FOR TRANSMITTING A DOWNLINK REFERENCE SIGNAL IN A WIRELESS COMMUNICATION SYSTEM SUPPORTING MULTIPLE ANTENNAS - A method for a base station to transmit a channel-state-information reference signal for up to 8 antenna ports includes mapping, in accordance with a predetermined pattern, the channel-state-information reference signal for up to 8 antenna ports onto a data region of a downlink subframe having an extended cyclic prefix (CP) structure, and transmitting the downlink subframe onto which the channel-state-information reference signal for up to 8 antenna ports has been mapped; and, in the predetermined pattern, the channel-state-information reference signal for up to 8 antenna ports in mapped onto 2 OFDM symbols on the data region of the downlink subframe, with a definition for mapping onto at least one of 4 subcarrier wave positions in each of the 2 OFDM symbols, and the 4 subcarrier wave positions defined in the predetermined pattern can be disposed at 3 subcarrier wave intervals. | 2012-05-17 |
