Abstract

A technique for selecting a transport format for a multiple-input multiple-output, MIMO, channel between a first station and a second station is described. The first station comprises M first antenna ports, wherein M≥2. The second station comprises N second antenna ports, wherein N≥2. As to a method aspect of the technique, a channel estimation is performed based on reference signals received at the M first antenna ports from a subset comprising Xsecond antenna ports among the N second antenna ports, wherein 1≤X<N≤M. The channel estimation results in a partial channel state relating to the Xsecond antenna ports to the M first antenna ports. At least one extended channel state is constructed based on the partial channel state.
