Abstract:
1. A method for managing interference from user equipment (UE) transmissions in a mobile telephony network comprising: gathering data at a base station of the mobile telephony network from a set of UE in range of the base station, wherein the mobile telephony network comprises at least one low-power cell having a cell range that overlaps a station range of the base station, wherein a subset of the UE transmits data to the low-power cell when within the cell range at a cell transmission power, wherein the subset of UE transmits data directly to the base station at a default station transmission power when within the station range and when outside an interference region, wherein the cell range is included within a periphery of the interference region, wherein the cell transmission power is less than the default station transmission power; detecting at the base station using the data that one of the user equipment (UE), referred to herein as an interfering UE is within the interference region, is outside the cell range, and that the transmissions of the interfering UE to the base station at the default station transmission power is producing high interference affecting uplink performance between a different UE and the low-power cell; in response to detecting, generating at the base station a power adjustment message; and conveying the power adjustment message from the base station to the interfering UE, wherein the power adjustment message causes the interfering UE to lower its transmission power from the default station transmission power to a lower power level.
