  • Patent number: 10341076
    Abstract: In Down Link MU-MIMO, an AP transmits to several STAs concurrently. In the mmWave band, directional transmissions are used so it is necessary for both the AP and the STAs to set their antenna arrays (by setting their antenna weight vectors—AWVs) in the best way to receive the transmissions directed to them by the AP and to avoid interference from transmissions directed to other devices. An exemplary embodiment discloses a beamforming training protocol that is capable of generating a set of antenna weight vectors for MU-MIMO operation that at least improves performance of subsequent communications.

  • Publication number: 20190173557
    Abstract: Various embodiments may be generally directed to antenna array weight vector selection techniques for 60 GHz multiple-input multiple-output (MIMO) communications. In some embodiments, using one or more such techniques, a 60 GHz-capable transmitting device may select respective antenna array weight vectors for two or more transmit antenna arrays, and a 60 GHz-capable receiving device may select respective antenna array weight vectors for two or more receive antenna arrays. In various embodiments, in order to obtain information for use in selecting such antenna array weight vectors, the transmitter and receiver may utilize one or more existing beamforming training algorithms defined for 60 GHz single-input single-output (SISO) communications. In some embodiments, for example, the transmitter and receiver may utilize one or more beamforming training algorithms defined in IEEE 802.11ad-2012. The embodiments are not limited in this context.
