Multi-user and single user MIMO for communication systems using hybrid beam forming

摘要

A station in a wireless communication system includes a processor circuitry configured to form at least a first plurality of data streams and a second plurality of data streams, and a digital precoder configured to receive the first plurality of data streams and the second plurality of data streams. The wireless station can further include a plurality of radio frequency (RF) beamforming chains connected to the digital precoder and configured to form at least one RF envelope, wherein the digital precoder is configured to steer a plurality of digital beams within the at least one RF beam envelope, the digital beams forming a plurality of spatially distinct paths for the first plurality of data streams and a plurality of spatially distinct paths for the second plurality of data streams, and a plurality of antennas operably connected to the RF beamforming chains.
