US 11,540,143 B2 · Integrated relay distributed antenna system

Abstract

In one example, an integrated relay distributed antenna system includes a relay node communicatively coupled to a base station and a master unit communicatively coupled to the relay node. The relay node is configured to communicate with the base station via a backhaul interface. The master unit is configured to communicate with the relay via an access interface, and the master unit and the relay node are configured to communicate demodulated and decoded data and/or demodulated data with each other. The integrated relay distributed antenna system further includes one or more remote antenna units communicatively coupled to the master unit and located remote from the master unit, wherein the one or more remote antenna units are configured to provide radio frequency signals to a coverage zone via one or more antennas.

Dependent claims

An integrated relay distributed antenna system, comprising:

a relay node communicatively coupled to a base station, wherein the relay node is configured to communicate with the base station via a backhaul interface, wherein the relay node is configured to demodulate and decode downlink signals from the base station to recover control-plane and user-plane data;
a master unit communicatively coupled to the relay node, wherein the master unit is configured to communicate with the relay node via a first transport interface, wherein the master unit and the relay node are configured to communicate demodulated and decoded data and/or demodulated data with each other;
and
one or more remote antenna units communicatively coupled to the master unit and located remote from the master unit, wherein the one or more remote antenna units are configured to provide radio frequency signals to a coverage zone via one or more antennas;
wherein the master unit and/or the one or more remote antenna units are configured to demodulate and decode uplink signals from user equipment in the coverage zone to recover control-plane and user-plane data.

A master unit of an integrated relay distributed antenna system that includes a relay node, the master unit, and one or more remote antenna units, the master unit comprising:

a first transport interface configured to communicate demodulated and decoded data and/or demodulated data with the relay node;
an access interface configured to implement communication between the master unit and the one or more remote antenna units of the integrated relay distributed antenna system, wherein the one or more remote antenna units are configured to provide radio frequency signals to a coverage zone via one or more antennas;
a second transport interface configured to output demodulated and decoded downlink data and/or demodulated downlink data to the one or more remote antenna units, wherein the second transport interface is configured to receive demodulated and decoded uplink data and/or demodulated uplink data from the one or more remote antenna units;
and
a controller configured to modify demodulated and decoded data and/or demodulated data exchanged between the master unit and at least one of the relay node or the one or more remote antenna units.
