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
