Submission doc.: IEEE /0316r0 Low Complexity Beamtraining for Hybrid MIMO Date: Slide 1 March 2016 Authors: Dana Ciochina (SONY), Felix Fellhauer (Stuttgart University)

Submission doc.: IEEE /0316r0 Abstract Beam training for Hybrid MIMO in 11ay can be expensive as number of possible beam combinations grows exponentially with number of antenna arrays. This contribution proposes a low complexity beam training method for 11ay. The proposed method can be supported with minimal changes in protocols and frame structures of sector level sweep (SLS) and beam refinement phase (BRP) of 11ad. Results show significant reduction in complexity and negligible losses in resulting MIMO capacity compared to exhaustive search.
