摘要： An embodiment of the present invention relates to a method for performing spectrum sensing to detect a signal for a terminal of a primary user in each sensing node. The method for performing sensing may comprise the steps of: performing, by the sensing node, spectrum sensing to detect a signal for a terminal of a primary user; computing, by the sensing node, a local test statistic on the basis of the result of the spectrum sensing; calculating, by the sensing node, the transmission probability on the basis of the computed local test statistic; and transmitting, by the sensing node, sensing information to a convergence center on the basis of the calculated transmission probability. In this case, the convergence center can determine whether the signal for a primary user exists on the basis of the transmitted sensing information.

摘要： According to one embodiment of the present invention, a method for efficient channel use is disclosed. The channel use method may comprise the steps of: selecting a specific channel from channels configured to be shared along with a homogeneous or heterogeneous communication scheme; and performing an interference avoidance procedure if the selected channel interferes with a neighboring access point. The avoidance procedure may comprise one or more of a process of making a request to switch a channel of the neighboring access point, a process of notifying to the neighboring access point, and a process of changing the selected channel into another channel.
