    摘要: Embodiments of a multiple-input multiple-output (MIMO) communication system and methods for beamforming using polar-cap codebooks are generally described herein. Other embodiments may be described and claimed. In some embodiments, beamforming is based on codewords of a polar-cap codebook which represents deviations in the channel with respect to codewords of a full-manifold codebook.

    摘要: This disclosure describes systems, and methods related to parallel channel training in communication networks. A first computing device comprising one or more processors and one or more transceiver component may receive a first connection request from a second computing device, and a second connection request from a third computing device. The first computing device may determine a first training field associated with the first connection request and a second training field associated with the second request. The first computing device may send the first training field to the second computing device based at least in part on the first connection request and sending in parallel, the second training field to the third computing device based at least in part on the second connection request. The first computing device may establish a first spatial channel stream with the second computing device based at least in part on the first training field and a second spatial channel stream with the third computing device based at least in part on the second training field.
