Abstract:
Methods and network devices estimate power of signals received from a user equipment in a sector of a cellular network cell using a data signal, which is not a predetermined reference signal. An exemplary method includes (1) saving a data signal received from the user equipment in a first sector of the cellular network cell, (2) acquiring a reference signal that corresponds to the data signal as received in a second sector of the cell and demodulated, and (3) comparing the saved data signal and the reference signal to estimate power of the data signal as received in the first sector.
