Abstract
A transceiver and a method of controlling data transmission in a radio system, the method comprising transmitting packets from a first transceiver to a second transceiver, each packet having a given quality of service value. The first transceiver selects a stream of two or more available streams realized with a plurality of transmit antenna paths for the transmission of each packet on the basis of the quality of service value of each packet and the channel quality information of each available stream.
