Abstract: This disclosure provides methods, components, devices, and systems for beam search procedures for multiple spatial streams. Some aspects more specifically relate to beamforming training procedures for multiple spatial streams. The beamforming training procedures may provide beam separation between beams during the training procedure to prevent selecting beams which lead to inter-stream interference. In some examples, a multi-stream beamforming training procedure described herein may use antenna polarization to provide beam separation. For example, different radio frequency (RF) chains may use different antenna polarizations. Additionally, or alternatively, a multi-stream beamforming training procedure may provide beam separation through antenna orientation, where different RF chains use mutually exclusive beam search regions. Additionally, or alternatively, the responder wireless communication device may iteratively select beamforming directions for spatial streams, or one-by-one, and the initiator wireless communication device may perform additional beam searches excluding directions within beam widths of previously- selected beams.
