Abstract: Disclosed herein is a new type of fully-connected, hybrid beamforming transceiver architecture. The transceiver described herein is bi-directional and can be configured as a transmit beamformer or a receive beamformer. A method and apparatus are described that allows the beamformer to operate in “carrier aggregated” mode, where communication channels in multiple disparate frequency bands can be simultaneously accessed.

Abstract: Designs and techniques to enhance power-efficiency and incorporate new features in millimeter-wave MIMO transceivers are described. A new mechanism for built-in dual-band, per-element self-interference cancellation (SIC) is introduced to enable multi-antenna frequency-division duplex (FDD) and full-duplex (FD) operation. Additionally, several innovative circuit concepts are introduced, including low-loss wideband antenna interface design, dual-band power combining PA, dual-band RF-SIC design, and bi-directional MIMO signal path design.

Abstract: A reconfigurable, multi-band hybrid beamforming architecture is introduced. The present invention is related to a Cartesian-Combining architecture to efficiently implement RF beamforming for a single downconversion chain employing direct downconversion in which the Cartesian-Combining architecture is extended to hybrid beamforming and to heterodyne downconversion.

Abstract: Disclosed herein is an innovative multi-layer hybrid/digital MIMO architecture that comprises single-stream or fully-connected (FC) multi-stream beamforming tiles (with RF complex-weights) in the first layer, followed by a fully connected (analog/digital) baseband layer. This architecture overcomes the complexity versus spectral-efficiency tradeoffs of existing hybrid MIMO architectures and enables MIMO stream/user scalability, superior energy-efficiency, and spatial-processing flexibility.
