Abstract: An information exchange apparatus of each node for sharing information between a plurality of nodes receives request information from an adjacent node and determines an information transmitting node based on information that each node holds and request information from the adjacent node. The information exchange apparatus of a node that is determined to be an information transmitting node generates candidate transmitting information by performing network coding of at least one information set of held information, determines one of the candidate transmitting information sets as transmitting information, and transmits the candidate transmitting information set to the adjacent node.

Abstract: The deformation correlation matrix or a correlation matrix of each channel coefficient matrix from multiple reception nodes which shares a wireless resource, or correlation matrix of an interference channel coefficient matrix feeds back to a transmission node. And the transmission node decides a pre-coder based on a value which minimizes a value decided by the set of the correlation matrix of the interference channel matrix or a value which maximizes a value decided by the correlation matrix or the deformation correlation matrix of the channel coefficient matrix, respectively, and pre-codes a transmission signal by using the decided pre-coder.

Abstract: Provided is a method that a first terminal communicating with a base station directly communicates with a second terminal. In accordance with an embodiment of the present invention, the first terminal determines a first time point at which the first terminal transmits a first signal to the base station or receives the first signal from the base station. The first terminal determines a second time point at which the first terminal transmits a second signal for searching a terminal to the second terminal. The first terminal changes one among the first time point and the second time point when the first time point and the second time point are overlapped.

Abstract: In a method of estimating a channel in a multicarrier system, a channel path is estimated if a signal is received through a multi-path channel. A channel is estimated based on the signal received from the estimated channel path. A compressive sensing-based channel estimate for repeatedly performing such path estimate and channel estimate is carried out.

Abstract: 기지국으로 피드백 정보를 전송하는 장치가 개시된다. 피드백 정보 전송 장치는 채널 할당 정보를 수신하여, 피드백 정보에 해당하는 복수의 페이로드를 생성하고, 복수의 페이로드를 복수의 클래스 별로 다중화하여 복수의 다중화 페이로드를 생성한다. 이후 복수의 다중화 페이로드를 코드 다중화하여 코드분할 다중화 심볼을 생성하고, 코드분할 다중화 심볼에 채널 코드를 적용하여 무선 자원을 통해 기지국으로 전송한다. 이를 통해 채널 조건에 따라 적응적인 피드백 채널을 구성하여 피드백 채널을 위한 무선 자원을 효율적으로 이용한다.
