Abstract
The present disclosure provides a method () in a network device. The method () includes: determining () a number, N, of sets of beam vectors by: creating a first set of beam vectors orthogonal to each other; and determining an n-th set of beam vectors each obtained by linear combination of two or more beam vectors from the (n−1)-th set of beam vectors, where N and n are integers and N≥n>1. The method () further includes: selecting (), from one or more of the N sets, a plurality of beam vectors for beamforming of a radio signal.
