Auxiliary beam pairs are proposed in millimeter-wave cellular systems for closed-loop hybrid precoding. Pairs of custom designed analog beams are formed to help acquire channel information. It is shown via simulations that auxiliary beam pairs have lower complexity and better achievable rates with a moderate amount of feedback, compared to conventional beam training methods.
