Abstract: A method performed by a network node for creating a precoder for forming a Downlink, DL, beam between the network node and a User Equipment, UE, which DL beam is for reciprocity-based Multiple Input Multiple Output, MIMO, communication in a wireless communications network is provided. The network node obtains matched filter channel estimates for an Uplink, UL, signal, based on a reference signal from the UE known by the network node. The network node obtains a hypothesis testing space within a first precoder codebook, of one polarization, based on the matched filter channel estimates. The network node selects a set of precoder candidates out of the first precoder codebook in accordance with the hypotheses testing space. The network node creates the precoder for forming the DL beam between the network node and the UE, based on calculating a linear combination of the precoder candidates in the set of precoder candidates.

Abstract: A network node signals to a wireless communication device which precoders in a codebook are restricted from being used. The network node in this regard generates codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group by restricting a certain component (e.g., a certain beam precoder) that the precoders in the group have in common. This signaling may be for instance rank-agnostic signaling that jointly restricts the precoders in a group without regard to the precoders' transmission rank. Regardless, the network node sends the generated signaling to the wireless communication device.
