Repeater system and method for indoor distribution of cellular mmwave signals

Abstract

A repeater device having a donor radio antenna that captures publicly broadcast synchronization signals from an outdoor 5G Radio Access Network (RAN) node, and a controller that decodes the captured publicly broadcast synchronization signals. The controller synchronizes with the decoded publicly broadcast synchronization signals to align a frame structure of the donor radio antenna to a frame structure of the outdoor 5G RAN node, independent of additional signaling and explicit coordination from the outdoor 5G RAN node. The repeater device includes a relay radio antenna that communicates the synchronized publicly broadcast synchronization signals to a first set of indoor relay devices, and the controller executes frequency or spatial isolation to reduce interference between user equipment of one or more indoor UEs.
