Abstract
An embodiment of the present invention provides an apparatus, comprising a transceiver, an antenna tuner connecting said transceiver to an antenna, a power sensor adapted to acquire measurements about transmit power, a receive signal strength indicator (RSSI) adapted to acquire measurements about receive power and wherein said tuner tunes said antenna based upon said transmit and receive measurements to optimize said antenna in both the receive and transmit bands.
Claims20
A wireless communication device, comprising:
- a transceiver;
- an antenna;
- a tunable network including one or more adjustable reactance elements;
- a power sensor;
- and
- a receive signal strength indicator (RSSI),
- wherein the power sensor acquires measurements associated with transmit power during a first burst transmission,
- wherein the RSSI acquires measurements associated with receive power, and
- wherein the tunable network is adjusted once per frame prior to a second burst transmission based upon the measurements associated with the transmit and receive power to improve performance of the antenna in both receive and transmit bands, wherein both of the measurements associated with the transmit and receive power are utilized in determining the adjustment to the tunable network, and wherein the second burst transmission is subsequent to the first burst transmission.

A method, comprising:
- acquiring, by a power sensor of a communication device, measurements associated with transmit power during a first burst transmission;
- acquiring, by a receive signal strength indicator of the communication device, measurements associated with receive power;
- and
- adjusting, by a control circuit of the communication device, a tunable network of the communication device for each frame prior to a second burst transmission based upon the measurements associated with the transmit and receive power to improve performance of an antenna of the communication device in both receive and transmit bands, wherein the second burst transmission is subsequent to the first burst transmission.
