Patent number: 9531467Abstract: A communication system configured to send data using an interference alignment scheme is disclosed herein. The disclosed communication system includes an MS and a BS. The disclosed BS sends data using a transmission beamforming matrix that minimizes intra-cell interference. The disclosed MS receives the data using a reception beamforming matrix that minimizes inter-cell interference. The BS sends information about a reference beamforming matrix to the MS, and sends a pilot signal to the MS using the reference beamforming matrix. The MS estimates an effective channel using the reference beamforming matrix, and calculates the intensity of an interference signal from an interference BS.Type: GrantFiled: December 23, 2014Date of Patent: December 27, 2016Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION GYEONGSANG NATIONAL UNIVERSITY GAJWA-DONGInventors: Bang Chul Jung, Won Yong Shin, Hyun Jong Yang, Jae Joon Park, Kwang Jae Lim, Jae Sun Cha, Eun Kyung Kim, Hyun Lee, Sung Cheol Chang

Publication number: 20160095114Abstract: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band: The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.Type: ApplicationFiled: September 25, 2015Publication date: March 31, 2016Inventors: Eunkyung KIM, Jae Sun CHA, Chanho YOON, Seung-Kwon BAEK, Jae Joon PARK, Kwang Jae LIM, Sung Cheol CHANG

Publication number: 20140334356Abstract: An exemplary embodiment of the present invention provides a resource management method performed by a coordinator for controlling interference between cells. The coordinator receives a channel state of a second base station neighboring a first base station from the first base station. The coordinator partitions a resource based on the channel state. The coordinator allocates the partitioned resource to the first base station. In addition, the coordinator transmits a first message requesting resource management to be set to the first base station. Here, the first message includes information on the allocated resource.Type: ApplicationFiled: May 10, 2014Publication date: November 13, 2014Applicant: Electronics and Telecommunications Research InstituteInventors: Eunkyung KIM, Jae Sun CHA, Jae Joon PARK, Hyun LEE, Kwang Jae LIM, Sung Cheol CHANG
