Dynamic receive diversity switching

摘要

Dynamically control of receive diversity switching in a user equipment (UE) is disclosed. By dynamically controlling the switching between enabling and disabling the receive diversity, power consumption in UEs, such as smart phones and other mobile devices may be reduced. Control is based, at least in part, on measurements for data activity performed by the UE. When the UE finds measurements that would suggest data activity, the UE will switch to enable a receive diversity state when conditions are available for the switch. Similarly, when the UE finds measurements that would suggest data inactivity, the UE will switch to disable the receive diversity state when conditions are available for the switch.

1. A method of dynamically switching a receive diversity, comprising:
setting the receive diversity initially to an ON state; measuring data activity after expiration of a measurement interval; switching the receive diversity to an OFF state when the measured data activity indicates absence of data activity; maintaining the ON state when the measured data activity indicates presence of data activity; when in the OFF state, re-measuring the data activity after expiration of another measurement interval; switching the receive diversity to the ON state when the re-measured data activity indicates presence of data activity; and maintaining the OFF state when the re-measured data activity indicates absence of data activity.
