Biological tissue detection using differential beamforming in mobile communication systems

Abstract

A method comprising transmitting, via a first antenna array of a mobile communication device, a plurality of transmit beams, and receiving, via a second antenna array of the mobile communication device, a plurality of receive beams. Each beam pair of a plurality of beam pairs includes a respective transmit beam of the plurality of transmit beams and a respective receive beam of the plurality of receive beams. Then determining, based on a comparison between beam pairs of the plurality of beam pairs, whether an object is proximate to the mobile communication device. Then responsive to determining that the object is proximate to the mobile communication device, determining one or more transmission parameters. Then transmitting, with the one or more transmission parameters, a signal.
