Outdoor-Indoor MIMO Communication System Using Multiple Repeaters and Leaky Cables

摘要

A MIMO communications system for communicating with a UE located inside a physical structure. The communication system includes a node comprising two node antennas. The node is configured for LOS wireless communication with at least first and second repeaters. The first and second repeaters each have a) an antenna provided outside the physical structure for outdoor MIMO communication with the node and b) a leaky cable provided inside the physical structure for indoor MIMO communication with the UE.

1. A wireless outdoor-indoor multiple-input multiple-output (MIMO) communications system for communicating with a user equipment located in an interior space of a physical structure, comprising:
a first repeater; a second repeater; and a node having at least two node antennas and being configured for wireless communication with the first repeater and the second repeater, wherein said first repeater has a first repeater antenna provided outside said physical structure for communication with said node, said second repeater has a second repeater antenna provided outside said physical structure for communication with said node, said first repeater is connected to a first leaky cable provided inside said physical structure for indoor communication with said user equipment located in the interior space of said physical structure, said second repeater is connected to one or more of: said first leaky cable and a second leaky cable provided inside said physical structure for indoor communication with said user equipment, and said first and second repeater antennas are spaced apart such that a first radio channel between the node and the first and second repeater antennas supports a rank that is greater than or equal to two.
