Abstract
A method of operating a re-configurable reflective device, RRD () is provided. One or more wireless communication devices () are served by an access node () via the RRD () using multiple spatial data streams. The RRD () comprises multiple reflective elements (), the multiple reflective elements () being grouped into a plurality of subsets (-), the multiple reflective elements () of each subset (-) being re-configurable to provide multiple spatial filters. The method comprises obtaining, from the access node () and for each subset (-) of the plurality of subsets (-), a respective first indicator indicative of a respective entry of a respective first codebook and a respective second indicator indicative of a respective entry of a respective second codebook, and reconfiguring, for each subset (-) of the plurality of subsets (-), the respective multiple reflective elements () to provide a respective one of the multiple spatial filters, based on the respective entry of the respective first codebook and the respective entry of the respective second codebook.
