Google patents using smart surfaces to share 5G signals
This patent describes a way for cell towers to share a special smart surface to send data to each other. The system assigns specific parts of the surface to different towers so they can exchange signals without blocking one another.
In the filing’s own words
Techniques and apparatuses are described for integrated access backhaul with an adaptive phase-changing device (APD) are described. In aspects, a donor base station determines to include an APD in a communication path for the wireless backhaul link with a node base station and apportions APD access to the APD for the node base station. The donor base station then communicates with the node base station using the surface of the APD and based on the apportioned APD-access by using the surface to exchange wireless signals with the donor base station.
What exactly they claim (claim 1)
1. A method performed by a first base station for communicating over a wireless backhaul link with a node base station, the method comprising: determining to include an adaptive phase-changing device (APD) in a communication path for the wireless backhaul link; apportioning APD reflection-access to the node base station for communicating over the wireless backhaul link using a surface of the APD, the apportioning comprising indicating, to the APD, a node index from a codebook associated with the node base station; and communicating with the node base station over the wireless backhaul link using the surface of the APD and based on the apportioned APD reflection-access.
