Abstract
A mobile communication device includes a first wireless transceiver that receives a first inbound RF signal and that transmits a first outbound RF signal based on a first power supply signal. A second wireless transceiver receives a second inbound RF signal and that transmits a second outbound RF signal based on a second power supply signal. A processing module generates at least one power mode signal based on first transmit power control data received via the first inbound RF signal. A power management circuit adjusts a first power consumption parameter of the first power supply signal and a second power consumption parameter of the second power supply signal based on the at least one power mode signal.

A communication device comprising:
- a multi-input, multi-output (MIMO) transceiver for voice and data communication via a telecommunications network, the MIMO transceiver including:
- a first wireless transceiver configurable to receive a first inbound RF signal and configurable to transmit a first outbound RF signal at a first power level based on a first power supply signal;
- a second wireless transceiver configurable to receive a second inbound RF signal and configurable to transmit a second outbound RF signal at a second power level based on a second power supply signal;
- a processing module, coupled to the MIMO transceiver, configurable to generate at least one power mode signal based on first transmit power control data received via the first inbound RF signal from an external device;
- and
- a power management circuit, coupled to the processing module, configurable to adjust, based on the at least one power mode signal, at least one of:
- a first power consumption parameter of the first power supply signal;
- and a second power consumption parameter of the second power supply signal.
