Abstract
Official abstract text for this publication.
A method and apparatus can cut back power in a simultaneous dual frequency band call. The method may operate a dual frequency band transmit device. The method may include determining if a transmit frequency in a first frequency band from the device combined with a transmit frequency in a second frequency band from the device causes receiver desensitization at the device. The method may include determining if the transmit power in the first frequency band is above a threshold power. The method may include reducing maximum transmit power in the second frequency band by an amount proportional to transmit power in the first frequency band and transmit signal bandwidth in the second frequency band in only the portion of the second frequency band where a resultant frequency component can cause desensitization.
First claim
Opening claim text (preview).
We claim: 1. A method of operating a dual frequency band transmit device, the method comprising: determining if a transmit frequency in a first frequency band from the device combined with a transmit frequency in a second frequency band from the device causes receiver desensitization at the device; determining if transmit power in the first frequency band is above a threshold power; and reducing maximum transmit power in the second frequency band by an amount inversely proport…
