<p>The present invention provides a method and a device for delivering service data, so as to implement a calculation method with a simplified precoding matrix. The method comprises: executing, by a network side, the following steps: calculating a matrix of a value space according to a signal channel matrix of a serving cell of a terminal; calculating a matrix of a zero space according to a matrix of an interference channel of a collaborative cell of the terminal; projecting a vector of the value space to a plane on which a vector of the zero space is to acquire a precoding matrix of the terminal; delivering service data at the serving cell of the terminal according to the precoding matrix.</p> |
