METHOD AND SYSTEM TO IMPROVE ANTENNA TUNER RELIABILITY

摘要

A method and system performs antenna tuning which enhances radio frequency (RF) tuner reliability within a wireless communication device (WCD). The WCD, in response to receiving a request to change an active RF tuning state, retrieves component usage data corresponding to components of a tuning circuit that is tunable to an RF operating channel. The WCD selectively determines, using device environment state data and/or RF state data and the component usage data, an RF tuning state tuned to the RF operating channel. The selected RF tuning state (a) satisfies tuning performance specifications and (b) enhances component reliability performance by minimizing an operational wear on tuning circuit components. The WCD configures the tuning circuit using the selected RF tuning state and tracks session parameter values for tuning circuit components during a corresponding communication session. Following completion of the communication session, the WCD uses the tracked session parameter values to update component usage data.

1. A method for performing antenna tuning within a wireless communication device, the method comprising:
receiving a request to change a first radio frequency (RF) tuning state; retrieving component usage data corresponding to one or more tuning circuit components of a tuning circuit that is tunable to the first RF operating channel; retrieving information about at least one of (i) a device environment state and (ii) an RF state, where the at least one respective state is associated with a reliability performance of tuning circuit components when the tuning state is activated; selectively determining, using the retrieved component usage data and information about the at least one of the device environment state and the RF state, an antenna tuning state for the tuning circuit to tune to the first RF operating channel and which antenna tuning state (a) satisfies tuning performance specifications and (b) enhances component reliability performance by minimizing an operational wear on the one or more tuning circuit components; and performing antenna tuning to tune to the first RF operating channel using the antenna tuning state which satisfies tuning performance specifications and enhances component reliability performance.
