Samsung patents base station method to reduce signal interference
This patent describes a base station that listens to signals from nearby towers to detect when their data channels overlap. If it finds an overlap, the base station sends specific information to phones to help them avoid the interference.
In the filing’s own words
A base station device includes a communication circuit configured to receive a first signal from an external base station device and transmit a second signal to a user equipment, by using a plurality of antennas, and a processor configured to obtain resource allocation information of the external base station device based on the first signal, identify whether an interference cell occurs, and generate the second signal when the interference cell occurs, the second information including resource allocation information of the interference cell.
What exactly they claim (claim 1)
1. A base station device comprising: a communication circuit configured to: receive a first signal from an external base station device, and transmit a second signal to a user equipment, by using a plurality of antennas; and a processor configured to: obtain resource allocation information of the external base station device based on the first signal, identify, based on the resource allocation information of the external base station device, whether an interference cell is present, and generate the second signal based on identifying that the interference cell is present, the second signal comprising resource allocation information of the interference cell, wherein the processor is further configured to generate the second signal, based on at least one of: resource allocation information of a physical downlink shared channel (PDSCH) of the interference cell overlapping a signal of a serving cell, resource allocation information of a synchronization signal block (SSB) signal of the interference cell overlapping the signal of the serving cell, and resource allocation information of a channel state information-reference signal (CSI-RS) of the interference cell overlapping the signal of the serving cell.
