Patent ID: 11528667

Abstract:
A method is disclosed for determining an appropriate transmit power of a cell based on a desired coverage distance, comprising: initializing, at a cell, a cell reference signal transmit power at a high power level; broadcasting a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell; progressively lowering the cell signal power measure at the cell; broadcasting the lowered cell signal power measure; deriving a plurality of user equipment (UE) attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell; comparing the plurality of UE attach request distances against a maximum distance to obtain a number of UE attach requests received from UEs physically located beyond the maximum distance; and setting the cell reference signal transmit power based on the number of UE attach requests received from beyond the maximum distance, thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on UE attach requests received at the cell.
