Abstract

The present invention relates to a method in a receiver unit for selection of MIMO transmission mode in a radio telecommunication network. The method comprises a first stage comprising the steps of - estimating a channel quality parameter (10); - comparing said channel quality parameter with a first threshold value (20); - depending on if the estimated channel quality parameter is above or below said threshold, selecting if multiplexing gain will be utilized or not; and a second stage comprising - determining the optimal subset of transmitted streams if multiplexing gain is selected in said first stage (401-403). The invention furthermore relates to a user equipment and a radio base station for carrying out said method.
