AI Technical Summary

Technical Problem

Existing repeaters have limited beam capabilities when transferring relay signals in certain directions, making it difficult to expand the coverage area for terminal communication, especially when obstacles like shields are present.

Method used

A relay system comprising a relay donor that performs wireless communication using a first frequency band with a base station and multiple relay nodes that use both the first frequency band for communication with terminals and a second frequency band for communication with the relay donor, thereby expanding coverage.

Benefits of technology

The proposed system effectively expands the coverage area for radio communications by allowing multiple relay nodes to relay signals from a base station to terminals, even beyond obstacles, using different frequency bands.

Abstract

This relay system comprises: a relay donor that performs wireless communication with a base station, using a first frequency band; and a plurality of relay nodes that perform wireless communication with at least one terminal, using the first frequency band. The relay donor performs wireless communication with the plurality of relay nodes, using a second frequency band which is different from the first frequency band.
