Abstract
Systems and methods for port selection in a wireless communication system are disclosed. In embodiment, a method performed by a radio access network (RAN) node for mapping Sounding Reference Signal (SRS) ports to transmission layers comprises obtaining a channel matrix, H, for one subcarrier or a group of subcarriers for a particular User Equipment (UE) and transforming the channel matrix, H, using a Singular Value Decomposition (SVD) of the channel matrix to thereby provide a transformed channel matrix. The method further comprises computing beamforming weights using the transformed channel matrix. Embodiments of a RAN node are also disclosed.
