1. A device comprising:
- a matching network; and
a controller coupled with the matching network, wherein the device is coupled to a communication network including a plurality of cells, the plurality of cells including a serving cell used by the device and a neighboring cell, and wherein the controller facilitates performance of operations comprising;
adjusting a tuning state of the matching network;
determining a group of power offsets, each of the group of power offsets associated with a frequency in a sub-band of a group of sub-bands of the neighboring cell;
selecting a power offset from among the group of power offsets;
measuring a received power of a signal at a neighboring cell frequency received by the device from the neighboring cell to determine a measured receive power value; and
determining an offset power value associated with the neighboring cell frequency by adjusting the measured receive power value according to the selected power offset,wherein, by a procedure in which a tuning frequency is swept through the group of sub-bands of the neighboring cell, a distinct offset power value is determined for each of the group of sub-bands of the neighboring cell, resulting in a relative power function of frequency applicable to all of the sub-bands of the neighboring cell.
