Abstract
A base station includes a channel estimator, a scheduler, and a controller. The channel estimator estimates a channel matrix with respect to each of a plurality of terminals. The scheduler determines a transmission weight corresponding to each of the plurality of terminals on the basis of the channel matrix that is estimated by the channel estimator such that the transmission weight is orthogonal to a current channel matrix and a past channel matrix of a terminal that is a subject of interference. The controller controls, when the transmission weight is determined by the scheduler, the number of samples of the current channel matrix and the past channel matrix to which the transmission weight is to be orthogonal with respect to each of the terminals.
