Abstract
A method for estimating Multiple Input Multiple Output, MIMO, channel state information for a radio link between a first radio node including a number N, N≥2, of receiving antenna ports and a second radio node including a number M, M≥2, of transmitting antenna ports. The method includes obtaining partial channel state information from a reference signal transmitted by a number X, 1≤X<M, of said transmitting antenna ports and received by all of said receiving antenna ports, said partial channel state information providing a measure for the N×X propagation channels between all of said receiving antenna ports and said transmitting antenna ports. Also disclosed are corresponding devices and computer programs. Also disclosed is a method for controlling transmission based on estimated channel state information.
