Abstract
This invention presents a Wireless Smart Antenna apparatus (WSA) comprising a Base Station Side Radio Unit (BSSRU) and a User Equipment Side Radio Unit (UESRU), wherein if a BSSRU is distributed in the coverage area of a Base Station (BS), the BSSRU communicates with one or more (BSs) using a first frequency band F1 and simultaneously communicates with one or more UESRUs using a second frequency band F2, or if a BSSRU is integrated into a BS, the BSSRU communicates with the BS baseband through circuits and communicates with one or more UESRUs using the second frequency band F2, wherein a UESRU communicates with one or more distributed or integrated BSSRUs using the second frequency band F2 and simultaneously communicates with one or more User Equipment (UEs) using the first frequency band F1, wherein one or more WSAs enable Multi-User Multiple Input Multiple Output spatial multiplexing in the F1 frequency band with UEs distributed over their coverage areas.
