Samsung patents method to find 5G interference sources

Samsung describes a way for a base station to detect when a phone is suffering from interference caused by nearby cells. The system asks the affected phone to measure signals from neighboring areas and report back which sources are too strong.

Why it mattersThis helps network operators identify and fix signal problems that slow down data speeds in dense 5G environments.

In the filing’s own words

The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). Particularly, a method for operating a UE in a wireless communication system according to various embodiments of the present disclosure may include a step of receiving, from a base station, information indicating that CLI measurement is triggered by identifying the UE as a victim UE, a step of receiving one or more cell-level reference signals from one or more UEs in a second cell adjacent to a first cell in which the UE is positioned, after the CLI measurement is triggered, and a step of transmitting, to the base station, a cell-level measurement report including a result of measuring RSRP of the one or more received cell-level RSs.

What exactly they claim (claim 1)

1. A method performed by a base station in a wireless communication system, the method comprising: in case that channel quality information included in a channel status information (CSI) report received from a user equipment (UE) is less than a first threshold, identifying the UE as a victim UE; transmitting, to the victim UE, information indicating that CLI measurement is triggered; after the CLI measurement is triggered, receiving, from the UE, a cell-level measurement report comprising a result of measuring reference signal received power (RSRP) of multiple cell-level reference signals (RSs) of multiple cells adjacent to a first cell in which the UE is positioned; and identifying, based on the cell-level measurement report, a cell corresponding to RSRP greater than or equal to a second threshold as an aggressor cell, wherein the multiple cell-level RSs are transmitted with an identical sequence on an identical radio resource, and the first threshold and the second threshold are different from each other.
