METHOD AND APPARATUS FOR ANTENNA TUNING AND POWER CONSUMPTION MANAGEMENT IN A COMMUNICATION DEVICE

摘要

A system that incorporates teachings of the subject disclosure may include, for example, a controller that determines a radiated throughput for at least one of an uplink throughput or a downlink throughput of the communication device, reduces transmit power for the communication device responsive to the radiated throughput satisfying a predetermined throughput range, and tunes a matching network of the communication device responsive to the radiated throughput not satisfying the predetermined throughput range. Other embodiments are disclosed.

1. A mobile communication device, comprising:
a matching network in communication with an antenna and including an adjustable reactive element; a memory storing computer instructions; and a processor coupled to the memory and the matching network, wherein the processor, responsive to executing the computer instructions, performs operations comprising:
retrieving a tuning value from a look-up table of the memory, wherein the tuning value is empirical data based on at least one of a total radiated power or a total isotropic sensitivity;adjusting a reactance of the adjustable reactive element to perform first impedance tuning by the matching network based on the tuning value;determining a radiated throughput for at least one of an uplink or a downlink comprising the adjustable reactive element;responsive to the radiated throughput satisfying a predetermined throughput range, reducing transmit power; andresponsive to the radiated throughput not satisfying the predetermined throughput range, adjusting the reactance of the adjustable reactive element to perform second impedance tuning by the matching network, wherein the second impedance tuning includes selecting the reactance of the adjustable reactive element to increase the radiated throughput to satisfy the predetermined throughput range.
