1. A mobile communication device, comprising:
- a plurality of antennas including radiating elements;
phase shifters connected with the radiating elements;
a matching network including an adjustable reactive element, wherein the plurality of antennas is coupled with the matching network;
a memory storing computer instructions; and
a processor coupled to the memory and the phase shifters, wherein the processor, responsive to executing the computer instructions, performs operations comprising;
obtaining Received Signal Strength Indicator (RSSI) data;
performing beam forming based on the RSSI data utilizing the phase shifters;
determining whether a first throughput threshold can be satisfied;
adjusting the beam forming utilizing the phase shifters responsive to a determination that the first throughput threshold cannot be satisfied, wherein the adjusting of the beam forming is based on forming a desired antenna pattern that increases radiated throughput and reduces antenna coupling among the plurality of antennas;
responsive to the adjusting of the beam forming, determining radiated throughput for an uplink throughput;
responsive to a first determination that the radiated throughput satisfies a second throughput threshold, reducing transit power; and
responsive to a second determination that the radiated throughput does not satisfy the second throughput threshold, tuning the matching network.
