Implementing multi user multiple input multiple output (MU MIMO) base station using single-user (SU) MIMO co-located base stations

摘要

A system that implements multi user multiple inputs multiple outputs (MU MIMO) base station using a plurality of co-located single-user (SU) MIMO base stations is provided herein. The system may include a number N co-located single-user multiple input multiple output (SU-MIMO) bases stations each having a number K MIMO rank, wherein said N co-located SU-MIMO base stations are configured to share a common antennas array, operating over a common frequency band; a front-end MIMO processor connected to said N co-located SU-MIMO base stations and further coupleable to said common antennas array; and a back-end coordinator configured to collaboratively assist in optimizing operation of said N co-located SU-MIMO base stations, such that said N co-located SU-MIMO base stations and said front-end MIMO processor collaboratively implement a multi-user multiple input multiple output (MU-MIMO) base station capable of dynamically separating a coverage area into N*K spatial channels.
