Abstract
According to one embodiment there is provided a method performed in a transmitter side of a multiuser minimum square error linear precoding MIMO system that comprises a transmitter with a plurality of transmit antennae and a plurality of receivers. Each receiver of the plurality of receivers comprises a plurality of receive antennae. The method is a method of scheduling receivers from among the plurality of receivers and comprises obtaining, for some or all of the receivers, receiver channel information that quantifies the properties of transmit channels between receiver antennae of the receiver and transmit antennae of the transmitter and establishing an order for determining the receiver combining vectors of the some or all of the receivers. The order is established by selecting as a next receiver in the order a so far unselected receiver from the some or all of the receivers that minimally increases the mean square data transmission error. The establishing of the order is based on the channel information of any receivers previously selected in the order and of unselected receivers.
