Abstract
A mobile device comprises a receiver unit that has at least two receivers to implement multi-antenna receive diversity. A control unit estimates, at the mobile, an amount of utilization by a traffic channel of the mobile of total transmission power capacity at a base station. The mobile applies multi-antenna receive diversity in the mobile device based on the power capacity utilization. The mobile estimates an amount of power a network is transmitting to the mobile relative to a pilot reference. Other indicators are based on quality of the traffic channel between the mobile and the network, capacity limiting resources, a number of sectors in a soft hand-off in a wireless system, etc. The indicators are used to control application of multi-antenna receive diversity in a mobile device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
